To increase torque capacity, power transmission friction mechanism can be more friction disk type friction mechanisms, be at least in its quantity
One and two groups of friction plates of axially staggered arrangement, are non-rotatably respectively connecting to friction member and guide.
It should be strongly noted that the implication of related notion used in present specification or term is as follows：
Set indirectly：It is arranged on the non-rotatable other components being connected of destination component with setting.
Rotate guiding mechanism：Circumference is converted to the guiding including at least axially opposing movement or mobile trend
Mechanism.For example, the slides/rolls formula spiral or part helix mechanism of lead angle strict conformance and not strict conformance, radial peg
Groove mechanism, end face wedge mechanism, end face embeding mechanism, end ratchet mechanism, and, cylinder/end cam mechanism.
Space wedge mechanism：The composite structure being made up of rotation guiding mechanism and traction friction mechanism.
Enter wedge：Also referred to as wedging, with solution wedge/remove wedge on the contrary, being exactly that intermediate piece 90 is directed to part 50 and friction member 70 and can driven
Ground connects/is combined into the course of work and state of a friction piece.
ζ and ξ：The Important Limit angle of space wedge mechanism, intermediate piece 90 as shown in Figure 1, 2, 3, on the one hand, rubbed by it
Wiping face such as 104 and the traction rubbing surface 72 of friction member 70 at least axially contradict, to form the conjunction for the normal pressure for contradicting position
Power W is not orthogonal to axis of rotation X rotary type traction friction mechanism F1 one group of traction friction pair for comprising at least one；It is another
Aspect, the spigot surface such as 94a by it towards a certain circumferencial direction, spigot surface such as 54a corresponding to guide 50 is at least
Axial direction is contradicted, and axis of rotation X rotation guiding mechanism G is not orthogonal to extremely to form the N that makes a concerted effort for the normal pressure for contradicting position
Include one group of guiding friction pair of one less；The common tangent at the conflict position and the angle of the plane perpendicular to axis of rotation X
Average value, it is referred to as the lift angle λ at the conflict position；Another further aspect, it can also be acted on such as elastic pretension by other surfaces
Or other active forces of spacing purpose, such as Fig. 1,2,4A~4D, shown in 5~7；Work is oriented in the rotation for rotating guiding mechanism G
In condition, that is, guide 50 starts constantly have the driving arrow P direction Relative frictions along such as Fig. 3 of intermediate piece 90
In the trend that part 70 rotates, it can be ensured that the minimum lift angle for being oriented to the both sides surface conflict position of friction pair self-locking is defined as ζ,
And maximum lift angle is then defined as ξ.Two limiting angles define the counter-guide 50 of intermediate piece 90 and rotate forward, be static completely
Every forms of motion that is motionless and rotating backward.Concrete meaning is as follows：
1st, as 90 degree of ξ ＜ λ ＜, it is oriented to friction pair and traction friction pair is unable to friction self-locking, by being oriented to friction pair
Normal pressure N, or its component Q and T, guide 50 and friction member 70 can cause intermediate piece 90 it is relative the two forward that is, arrow
Head P directions are trackslipped and extruded.Therefore, guide 50 and friction member 70 can not be by the wedgings of intermediate piece 90 into a friction piece.
Only because pressure N is derived from non-resilient power, or limited from elastic force but by element structure, just cause intermediate piece 90 only to be led
Promote the friction of Relative friction part 70 to trackslip to part 50 and do not extruded actually.
2nd, as ζ ＜ λ≤ξ and λ ＞ 0, traction friction pair has breaks through itself static friction state/resistance prior to being oriented to friction pair
The characteristic of power and entrance sliding friction state.Therefore, intermediate piece 90 can be directed to part 50 and be rubbed with the wedging of friction member 70 into one
Rub body, but when the counter-guide 50 of friction member 70 overloads, traction friction pair will break through its static friction state/maximum static friction
Resistance and be normally transferred to sliding friction state, and be oriented to friction pair then because not breaking through its static friction state/resistance also and all the time
In constant self-locking state.Accordingly, space wedge mechanism is in half wedging state, and freewheel clutch is in and non-fully engaged
State.
3rd, when 0 ＜ λ≤ζ (situation for being directed to ζ ＞ 0), it is quiet with itself is broken through prior to traction friction pair to be oriented to friction pair
The characteristic of Frotteurism/resistance and entrance sliding friction state.Therefore, intermediate piece 90 can be directed to part 50 and the wedge of friction member 70
Synthesize a friction piece, but when the counter-guide 50 of friction member 70 overload, guiding friction pair will break through its static friction state/
Maximum static friction resistance and cause intermediate piece 90 that there is counter-guide 50 to trackslip the trend climbed, and draw friction pair then because and also
Its static friction state/resistance is not broken through and is in constant self-locking state all the time.However, because above-mentioned trend of climbing is by space wedge
The axial force enclosed construction of shape mechanism is rigidly prevented (except non-pressure N is derived from elastic force), therefore, is oriented to friction pair by actually strong
Maintain to property processed the general static friction state for being equal to self-locking.That is, intermediate piece 90, guide 50 and the three of friction member 70 are strong
Wedging processed/be combined into a rotation entirety, is not in the situation mutually trackslipped and climbed, except non-overloaded to structure damage.Space
Absolute self-locking/wedging state of the wedge mechanism thus in similar diagonal-bracing type freewheel clutch, its transmission capacity are only dependent upon knot
Structure intensity.
Obviously, above-mentioned lift angle λ is exactly the angle of wedge of space wedge mechanism, also referred to as wedging angle/choke angle, and only 0 ＜ λ≤
During ξ, space wedge mechanism can wedging, frictional connectors can engage.
Compared with the prior art, the automatic control type spatial-wedging friction connector according to flexible engagement of the invention, because its is complete
The design feature of comprehensive engagement friction pair, and with the transmission capacity and service life at least to double, and make freewheel clutch sheet
Body is provided with the ability of flexible engagement first.By the explanation and accompanying drawing of following embodiments, objects and advantages of the present invention will be aobvious

Part.Preferably, benchmark projection 122 and the circumferential free degree of baseline trough 124 are equal to zero.
The arm of force 95 of pedestal is set as guide protrusions 132, and it has the similar arm of force 55 but appropriate inside in circumference
Inclined circumferential flank surface 116, it can make most preferably to be formed between the arm of force 95 and two circumferential wall 85a and 85b of entrance 82
Running clearance ε '.The gap/circumferential free degree ε ' should arrive such degree greatly, i.e. realize that it will without prejudice to guiding mechanism G is rotated
Guide 50 and friction member 70 are rigidly contradicted to two inner faces of circumferential recess 78, that is, are contradicted to support end face 189
With power transmission rubbing surface 58, so as to set up rigid axial force it is closed contradict connection purpose, regardless of whether its both ends sets
It is equipped with spring 100.
In setting, attitude reference device C has the effect that.That is, benchmark projection 122 is always positioned in baseline trough 124, is oriented to
Projection 132 can be located in baseline trough 124 and guide groove 134 respectively, that is, guide groove 134 has shared one of baseline trough 124
Point.When guide protrusions 132 are located axially in baseline trough 124, benchmark projection 122, the circumference of guide protrusions 132 are freely
Degree, only allow guiding tooth 92 and 52 mutually to be contradicted on a circumferencial direction, and cause intermediate piece 90 to enter wedge.It is for example, corresponding
The spigot surface 54a and 94a of arrow P directions in Fig. 3, and in arrow R directions, spigot surface 54b and 94b can not
On mutually contradicting.When guide protrusions 132 are located axially in guide groove 134, benchmark projection 122, the week of guide protrusions 132
To the free degree, it will allow to be oriented to tooth 92 and 52 and can mutually be contradicted on two different circumferencial directions, that is, can cause
Jie's part 90 enters wedge.
Then, as long as by for example unshowned known shift fork being arranged in slip ring groove 126, verge ring 120 is driven
Moved axially with respect to limiter element 180, cause guide protrusions 132 respectively in baseline trough 124 or guide groove 134, can incited somebody to action
Frictional connectors S1 is respectively set as mono-directional overrun clutch and shaft coupling mode of operation, it is had when may be used as reversing
The automobile-use for having wheel function can control type glider.Position shown in Fig. 3, i.e., it is set to list corresponding to frictional connectors S1
To the situation of freewheel clutch/glider.
Obviously, if it is desired, as long as the profile that guide groove 134 is altered as desired is set, make the counter-guide 50 of intermediate piece 90
With three different relative position/sections, frictional connectors S1 will be easy to have two-way wheel function, and can be distinguished
It is set as double rolling key clutch and shaft coupling mode of operation.
In addition, to make sliding corner, close in zero, frictional connectors S1 also most preferably sets flexible pretightening machine
Structure.The mechanism mainly include it is at least one be specially helical compression spring spring 150, it, which is arranged on, is oriented to tooth 52,92 both sides
Between crest top land and bottom of the tooth face.For example, being arranged in the axial hole for being oriented to the bottom of the tooth face of tooth 92, outer end is contradicted to guiding tooth 52
Crest top land, referring to Fig. 1,2.In fact, spring 150 can have arbitrary form and any setting made of elastomeric material
At least one flexible member of position, as long as it can most preferably cause to turn round rubbing surface 104 and flexibly contradict all the time to leading
Draw rubbing surface 72.
Entirety above with reference to two basic patent applications as described in, elastic pre-tightening mechanism also non-invention it is required.
When being not provided with the mechanism, although reliability decreases, frictional connectors S1 still can be by the special of lift angle λ 0 ＜ λ≤ζ
Set, and cause intermediate piece 90 to enter wedge by inertia when for example circumferentially rotating.
It is seen that during mode of operation in mono-directional overrun clutch, the frictional connection mechanism in frictional connectors S1
The course of work will be very simple, there is no essential difference with prior art.For example, when guide 50 starts constantly to have along figure
1st, arrow P direction Relative frictions part 70 makees the initial instant for the trend that driving rotates in 3, and friction member 70 will rub by traction
Mechanism F1 zero load/traction friction torque is wiped, draws the intermediate piece 90 for rotating guiding mechanism G, counter-guide 50 is along arrow R
Direction rotates guiding movement.Axial movement/tension force caused by the rotation guiding movement, it is being directed to the moment of tooth 92
Wedging is in the end face wedge shape space that spigot surface 54a and traction rubbing surface 72 are surrounded, that is, intermediate piece 90 is directed to part 50
While with the wedging of friction member 70 into a friction piece, traction friction mechanism F1 thus axial engagement, the tension force will also friction
The swelling at once of part 70 is closed to form axial force on the corresponding inner face i.e. power transmission rubbing surface 58 of limiter element 180
The mode of connection is contradicted, causes power transmission friction mechanism F2 also synchronously to engage, and by (combined type pouch-shaped) guide 50 and friction member
A friction piece is directly connected into 70 circumferences.Referring to Fig. 2 the latter half.
Then, frictional connectors S1 engages with the wedging of space wedge mechanism.By the first axle on inner peripheral surface 84a
200 incoming driving torque M0, the guide 50 and limiter element 180 of circumferential one are delivered separately to, is separated into via rotation
The wedging friction torque M that guiding mechanism G and traction friction mechanism F1 are transmitted1, and directly transmit via power transmission friction mechanism F2
Power transmission friction torque M2, friction member 70 is delivered separately to, and through the spline pair of the latter's inner peripheral surface, it is defeated to pass to the second axle 210
Go out.Wherein, M0=M1+M2.Obviously, the size of above-mentioned axial tension force, wedging power/engaging force and each frictional force, it is completely adaptive
It is proportional to M with answering1, that is, driving torque M0。
And when guide 50 starts constantly to have the arrow R direction Relative frictions part 70 along Fig. 1,3 to make solution wedge turn
The initial instant of dynamic trend, guide 50 will start to make to release the guide effect for rotating guiding mechanism G relative to intermediate piece 90
Rotate.Therefore, the normal pressure between spigot surface 54a and 94a and rotation guiding mechanism G rotation guide effect, will be with two
Spigot surface produces and is mutually disengaged disappearing in a flash and simultaneously for contact trend.Naturally, axial movement/swelling based on mechanism G
Power and the two friction mechanism F1 and F2 and whole space wedge mechanism to work, will separate or solve immediately wedge.Then, friction connects
Meet device S1 to terminate to engage and start to surmount rotation, intermediate piece 90 follows the Relative friction part 70 of guide 50 to trackslip along the friction of R directions.
Referring to Fig. 2 top halfs.
Far and away, due to the symmetry in circumference, the arrow R direction Relative frictions part 70 along Fig. 1,3 of guide 50
Rotation, that is, when frictional connectors S1 is in the mode of operation of the mono-directional overrun clutch of opposite direction, it has complete naturally
Similar to the upper course of work, herein without the necessity repeated.Certainly, torque can also be transmitted by path contrary to the above, and
The course of work does not have any essential difference.
Equally without doubt, when frictional connectors S1 is in shaft coupling mode of operation, it is in two different circumference
Work on direction rotates, and will all be engaged because of the wedging as described above of frictional connection mechanism therein, so as to be not present
Solve the course of work of wedge.So necessity without explanation.
Above-mentioned technical proposal has been fully recorded in the two basic patent applications integrally combined above, and not
It is the feature technology of the application.What present application illustrated focuses on, and how to realize the setting of flexible engagement and operating mode.For this mesh
, at least one damping mechanism D is specially provided with frictional connectors S1, and, most preferably corresponding flexible member.
Referring to Fig. 2,3,4A, to realize flexible engagement, that is, the purpose of most preferably elastic wedging, in frictional connectors S1
Lift angle λ be arranged to 0 ＜ λ≤ζ (as ζ ＞ 0), also, also in guide 50 and the support end face 51 of the both sides of limiter element 180
And between 189, it is spaced with least one flexible member, such as dish or diaphragm spring 100.The spring 100 is with formation elasticity
The form of axial closing power, the elasticity that the rotation guide effect between guide 50 and intermediate piece 90 provides gradual change is axially swollen
Clamp force.At least one spacer pin 176 being arranged in the respective radial holes of inner surface 80 of limiter element 180, with the side that can be trackslipped
Formula is axially contradicted to the respective flanges on the outer peripheral face of guide 50, causes guide 50 to keep its precompressed to spring 100
Contracting, so that it is guaranteed that axial freedom/gap of friction member 70 can most preferably be more than or equal to zero.
In fact, spring 100 is arranged on what is be not required between two axial resistance surfaces of geo-stationary.It can be set
Positioned at rotate guiding mechanism G axial either end and/or both ends other any two components between, as long as bullet can be formed
The axial closing power of property.
Accordingly, frictional connectors S1 is additionally provided with to delay the relative rotation speed between guide 50 and intermediate piece 90
The damping mechanism Da and Db of degree.Two damping mechanism D are most preferably cylinder-piston mechanisms, are most preferably symmetricly set in power respectively
The circumferential both sides of arm 95.It includes, and is most preferably persistently suppressed to the piston 20 of circumferential wall 85, is disposed radially within by spring 22
On the corresponding outer peripheral face of intermediate piece 90, or it is arranged in circumferential flank surface 116, for slidably receivable piston 20 and spring 22
Piston hole 24, be accommodated in the fluid of piston hole 24, such as air, brake fluid or coolant, and by intermediate piece 90 and tubulose
The damping hole or damping gap that gap between the inner and outer circumferential surfaces of matrix 76 is served as.
In setting, spring 100, two damping mechanisms Da and Db etc. have the effect that.That is, guiding mechanism G is rotated not
When producing guide effect, axial freedom of the intermediate piece 90 between guide 50 and friction member 70 should most preferably be more than zero.And
Spring 100 is compressed axially to the limit by the rotation guide effect for rotating guiding mechanism G, causes guide 50 firm by spring 100
Property contradict to support end face 189 before, piston 20 is not compressed into the limit most preferably yet, or circumferential flank surface 116 does not contradict yet
To circumferential wall 85.
Therefore, in frictional connectors S1 engaging processes as described above, as the rotation for rotating guiding mechanism G is oriented to fortune
Dynamic beginning, that is, with the beginning that the counter-guide 50 of intermediate piece 90 and limiter element 180 rotate, intermediate piece 90 will be as preceding
Literary described ground counter-guide 50, which trackslips, to climb.The relative rotation by guide 50 while spring 100 are compressed axially, also
Contradicted by circumferential wall 85a or 85b slip-style, overcome the resistance of spring 22 and the pressure of the fluid in piston hole 24,
Start to cause corresponding damping mechanism Da or Db piston 20a or 20b radially to bounce back.Now, frictional connectors S1 friction connects
Connection mechanism will contradict connection because of flexible and nonrigid axial force is closed, and elastic wedging type corresponding to entering connects
Conjunction state.
Then, the wedging friction torque M transmitted completely via guiding mechanism G is rotated originally1, torque M will be reduced to1', point
The part torque M of stream11, intermediate piece 90 will be directly passed to by guide 50, led so as to destroy temporarily through damping mechanism D
Draw the friction self-locking that friction mechanism F1 should have, in other words, ζ is temporarily reduced to ζ ', the lift angle λ of design has been more than this
ζ′.Therefore traction friction mechanism F1 will be in slip-style Frotteurism, and power transmission friction mechanism F2 also rubs naturally in identical
Wipe slip state.The torque that the friction is trackslipped, by corresponding to the elastic force of spring 100, and it is dynamic when being no longer correspond to rigid wedging
Power torque M0.Obviously, set by simple, it is easy to ensure to shunt torque M11It is enough compression piston 20, and given
In damping time, for example, in 0.5~2 second, the planar disc that spring 100 to the limit, is also compressed to the limit simultaneously is compressed it.
Finally, frictional connectors S1 frictional connection mechanism will be because of contradicting connection with rigid axial force is closed, and is transferred to pair
The rigid wedging type engagement state answered.It is completely corresponding to friction torque M1Rigid axial tension force, will force traction rub
Mechanism F1 utterly friction self-lockings, so as to terminate the frictional connectors S1 flexible engagement process for trackslipping frictional.
It can be seen that traction friction torque Ms of the frictional connectors S1 because of the elastic wedging stage1' be no longer relevant to by guide 50
The power torque M of input0, and the Fluid pressure of the elastic force and damping mechanism D only only in relation to spring 100, draw rubbing machine
Structure F1 thus be provided with the ability that can overload skidding, when frictional connectors S1 rigidity wedgings untill.Therefore, coasting mode
In, either because giving it the gun, or because utilizing the Reduced Speed Now of engine braking, frictional connectors S1 is in two circumference
It wedging/engaging process again on direction, all will be the process of flexible engagement, the impact of machinery will not be produced, or, significantly
Torque shock ends.As long as setting damping mechanism D relevant parameter, frictional connectors S1 damping process, it is possible to be and operation
Person is unrelated and only presses the process that the prior wish of designer is carried out.
And during frictional connectors S1 terminates engagement/wedging as described above and starts to surmount rotation, drawn
The intermediate piece 90 that friction mechanism F1 drives, its circumferentially opposed position before climbing of trackslipping is turned back to by counter-guide 50 first
Put.Accordingly, damping mechanism D spring 22, while the elasticity of piston 20 is extrapolated and is contradicted again to circumferential wall 85, also
By above-mentioned fluid via the gap between the inner and outer circumferential surfaces of intermediate piece 90 and tubular matrix 76, sucker hole 24.So as to cause to hinder
Buddhist nun mechanism D returns to SBR, waits the beginning of damping process next time.
So far it is seen that, torque all contacts friction pair transmission, its bang path in frictional connectors S1 via face
It is upper that any discrete elements are not present, in the absence of any frictional force related to centrifugal force, any time that can not be balanced less be present
Turn component and any uneven radial load or its component, all active forces only have axial thrust load and/or circumferential component, and are somebody's turn to do
The effective object of two component is respectively provided with high axial direction and/or circumferential rigidity again.Therefore, flexible can tie compared with the prior art
Auto-controlled clutch/connector of conjunction, frictional connectors S1 remove with entirety above with reference to two basic patent applications described in
The advantages of outside, it is clear that also there is the transmission capacity that at least doubles and service life, and, simpler structure, smaller axle
To/radial dimension, smaller quality, it is easier to adjustment control, and be easier to hugeization and miniaturization the advantages of.
It should be noted that to seek bigger design freedom and space wedge mechanism is easier wedging or solution wedge,
The present invention also has the technological means of various lifting limiting angle ζ and ξ numerical value.Including the guiding mechanism G He of spigot surface 54 will be rotated
94 are arranged to the tilted spiral type flank of tooth, the rubbing surface 72 and 104 for drawing friction mechanism F1 are arranged into frusto-conical surface, to cause axle
The cone-apex angle of the angle of spigot surface 54 and 94 or rubbing surface 72 and 104 and axis X in section/half is no longer equal to 90 degree, and is equal to 0
Other values between~180 degree；Traction friction mechanism F1 is arranged to more friction disk type friction mechanisms；And it will be provided with bigger
The material or element of coefficient of friction are attached at least one in rubbing surface 72 and 104.Here should incidentally, this theory
Bright book has been presented for the clearly literal definition and explanation on limiting angle ζ and ξ, without paying any performing creative labour,
One of ordinary skill in the art can derive its functional relation/calculation formula accordingly.
From general knowledge, for increase equivalent diameter when frictional connectors S1 torque capacity/transmission capacity and reduce axial direction
Tension force, traction friction mechanism F1 and power transmission friction mechanism F2 also can separately or concurrently be set as described above according to known technology
More friction disk type friction mechanisms are set to, and therefore and with one group of traction friction pair more than one in quantity or power transmission friction
It is secondary.
In addition, as described in definition, the present invention does not make specific limit to rotating guiding mechanism G and its being oriented to tooth 52,92
System, it is not necessarily to have optimal spiral toothing, is also not necessarily to the complementary guiding flank of tooth.Therefore, guiding mechanism G and
It, which is oriented to tooth and is oriented to the flank of tooth, can have the form and shape for arbitrarily possessing and rotating guide function.Being oriented to tooth can be set by discrete form
Put on end face/side face, also can be circumferential to be arranged on corresponding inner/outer circumference with continuing by such as single head or multiple-threaded mode
On face.And in latter arrangement form, it can most preferably be arranged to have rectangle, trapezoidal, zigzag or triangle etc.
The helical tooth of cross sectional shape.As a same reason, as long as axial complementary fitting/conflict can be best accomplished, rubbing machine is drawn
The tapering shape rotary type rubbing surface of structure F1 and power transmission friction mechanism F2 respective two groups of revolution friction pairs, any song can be based on
Line/bus forms around axis X revolution, and can be provided with radiating or excluding the discontinuous table of the groove of liquid/gas
Face.
The diagram and explanation of more multiple changing type about axial force enclosed construction and ring-type pocket member, reference can be made to institute is whole above
Two basic patent applications that body combines, and the applicant is in the Chinese patent literature CN102537126A being hereby incorporated by full
Middle announced technical scheme, the application will not be discussed further herein.
It should be noted that when frictional connectors S1 is used as into the glider of motor vehicles, should be most preferably by shaft coupling mould
The trigger switch of formula and reversing shifter linkage.In addition, also settable switching for example mechanically or electrically switchs, by its work
Pattern is set as mono-directional overrun clutch or shaft coupling.Moreover, can also further set manual including electrical actuator or
Automatic mode.In automatic mode, the action of brake pedal is trampled each time, will all cause frictional connectors S1 synchronous in linkage
Ground is transferred to or is maintained in the mode of operation of shaft coupling, so as to utilize the auxiliary brake function of engine, and steps on each time
Step on the action of accelerator pedal, the work that all frictional connectors S1 will be caused to enter or be maintained at freewheel clutch/glider in linkage
In operation mode.
In the present invention, damping mechanism D is clearly not limited to a kind of pattern and set location shown in the present embodiment.On the contrary,
It can have the pattern and set location required for any one, referring to follow-up explanation, as long as it is directly or indirectly set
Rotate two of guiding mechanism G or SG be oriented to teeth 52 and 92 either on 62 and 232 rotation path or axial movement road
On footpath, so as to delay the inconsistent relative rotation speed being oriented between tooth or axial movement.It can be direct or indirect
Ground be arranged between the component of two circumferentially opposed rotations or outside, including be separately or concurrently arranged on both axial, circumferential
Or between radial direction.Moreover, in the application for only needing unidirectional wedging and one-way flexible engagement, a damping machine more can be only set
Structure D.
For example, the piston hole 24 of the damping mechanism Da and Db in Fig. 4 B, substantially tangentially are symmetricly set on the arm of force 95
In two circumferential flank surfaces 116, piston 20 therein is flexibly contradicted to force-bearing pin 30.The force-bearing pin 30 is slidably disposed through position
Through hole is avoided in the axial direction on the arm of force 55, be fixedly attached to the corresponding axial hole positioned at 82 axial both ends of the surface of entrance with axially penetrating through
In.Damping hole 26 is extended to the surface of the arm of force 95 by the bottom of piston hole 24.Correspondingly, circumferential flank surface 116 is become by tangential type
For the radial mode shown in Fig. 4 B.
With contrast shown in Fig. 4 A~4B, the piston hole 24 of the damping mechanism D in Fig. 4 C is arranged on and limiter member
On the damping device 40 that part 180 is fixedly linked.The damping device 40 is that have substantially complementary construction with entrance 82 in a cross section
Arc block, it is integrally fixed by the force-bearing pin 30 axially penetrated through in its circumferential both sides with limiter element 180.Damping device 40
Circumferential center, is provided with the radial mode square hole of a circumferentially extending, and two piston holes 24 are symmetrically separately positioned on the square hole
Two circumferential walls on.The arm of force 95 in the square hole, it is modified to the radial protrusion that a peripheral side is arc-shaped curved surface.
In the circumferential compression process to piston 20, the arc-shaped curved surface can ensure that conflict point between the two, be always positioned at the head of piston 20
On end surface, the edge without reaching the end face.The damping hole 26 of the bottom of piston hole 24 is arranged on, can be extended directly to
Outer peripheral face, circumferential end faces can be also extended to as shown in Figure 4 C, and by the gap between damping device 40 and circumferential wall 85, be communicated to
Sunset circle.
Fig. 4 D show damping mechanism D another modification.Wherein, damping device 40 has H font knots as shown in Figure 4 E
Structure, have respectively to four lugs 42 and 46 of two circumferentially extendings, and therebetween two circumferentially extending type grooves 48.Four
The individual force-bearing pin 30 for being arranged on 82 axial both ends of the surface of entrance, extended respectively to by axial both ends in corresponding four pin-and-holes 44, will
Damping device 40 is fixedly linked with limiter element 180.Accordingly, the arm of force 95 is because being modified to two arm of force 95a with central gap
And 95b, respectively correspondingly in groove 48a and 48b, its radial mode medial surface contradicts to piston 20a and 20b respectively.Piston
Hole 24a and 24b are arranged on groove 48a and 48b circumferential wall substantially tangentially respectively in a manner of being axially staggered.
In addition, piston 20 obviously may also be arranged on circumferential wall 85 in such as Fig. 4 A, the damping hole in Fig. 4 B~4D
26, it is clear that the screw with conical nose can also be arranged to, to facilitate the valid circulation area of regulation damping hole, so as to change
Time corresponding to damping process.
As a same reason, attitude reference device C can also have it is any required for pattern and set location, as long as its directly or
It is respectively connecting to rotate guiding mechanism G two guiding teeth 52 and 92 indirectly, the counter-guide 50 of intermediate piece 90 can be limited
Circumferential position.Including only having an eccentric shaft type projection, and a cylinder being arranged on for example on guide 50
The axialmode cotter way formula embeding mechanism of cellular type groove.Even cotter way formula embeding mechanism, its is at least one raised and at least one
Groove, also can be at least indirectly being separately positioned on intermediate piece 90 and guide 50.More orientation schemes, reference can be made to the application
The Chinese patent application 201010624777.7 and 201210242218.9 that people is hereby incorporated by full, does not illustrate excessively herein.
It is important to point out that it can use simply circumferential press without the flexible member of such as spring 100 in the present invention
Contracting spring substitutes damping mechanism D, and elasticity resistance can be equally played before frictional connection mechanism enters rigid wedging/engagement state
Buddhist nun acts on.Although the effect of flexible engagement is weaker, can at least have the function that circumferentially to damp, mitigation friction can be played
The effect of mechanical shock when connector such as S1 is engaged.
Embodiment two：The automatic control type spatial-wedging friction connector S2 of flexible engagement
Different from the frictional connectors S1 of circumferential damp type, the frictional connectors S2 of modification has the damping mode of axial direction.
Accordingly, it, which rotates guiding mechanism G lift angle λ, should most preferably meet ζ ＜ λ≤ξ requirement.
Referring to Fig. 5, damping mechanism D is a ring-type cylinder-piston mechanism with limiter element 180 for cylinder body.It includes, if
The stepped cylinder groove in the support radially inner ring side of end face 189 is put, to form the two of closed cavity inner cylindrical wall faces,
And the air-ground annular piston 140 for being enclosed on the outer peripheral face of the second axle 210 and being provided with facing flange ring 142 that can trackslip., ring
Two corresponding outer peripheral faces on shape piston 140, are connected to above-mentioned two inner cylindrical wall face, and form cylinder-piston in which can trackslip
The ring-type damping cavity 144 of mechanism.Spring 100 is arranged in the damping cavity 144, and damping hole 26 is disposed radially within flanged ring 142
Inner peripheral surface on.
Further, since being not necessarily to set circumferential damping mechanism, naturally also just it is not necessarily to set the arm of force 95, therefore, is oriented to
Projection 132 is most preferably modified to an elastic straight steel wire.
Be readily apparent that by preceding description, in frictional connectors S2 engaging process, due to spring 100 elastic force by
It is cumulative big, and tension force caused by Fluid pressure relative rotation guiding mechanism G is relatively small in damping cavity 144, necessarily causes
Its frictional connection mechanism is in resilient wedge conjunction state, and traction friction mechanism F1 will connect because of overload in the flexibility that friction is trackslipped
During conjunction.And as above-mentioned tension force causes fluid in damping cavity 144 little by little to flow out, respective pistons ring 140 will be gradual
Ground compresses, and spring 150 will little by little push away intermediate piece 90 simultaneously, and caused axial gap will cause guide 50 relative naturally
Intermediate piece 90 rotates, so as to remain the friction contradiction between spigot surface 54 and 94, until spring 100 is compressed into pole
Limit.Hereafter, frictional connection mechanism will be transferred to closed contradict of rigid axial force as described above and connect, frictional connectors S2 knots
Beam flexible engagement process, into rigid wedging type clutching operation.
Should be in passing, it is noted that in assembling process, it is necessary to good spring 100 and piston ring 140 in place first, could incite somebody to action afterwards
Guide 50, intermediate piece 90 and friction member 70 for being pre-installed etc. are inserted in groove 78 by the radial direction of entrance 82.
Embodiment three：The automatic control type spatial-wedging friction connector S3 of flexible engagement
Referring to Fig. 6, frictional connectors S3 is the simple variant to frictional connectors S1, that is, exchanged intermediate piece 90 with
The position relationship of guide 50, so as to cause limiter element 180 and intermediate piece 90 non-rotatably to connect into a combined type bag
Shape intermediate piece.Therefore, spring 100 is arranged between intermediate piece 90 and the support end face 91 and 189 of limiter element both sides, guide
50 inner ring sides are provided with the tubular matrix 60 extended in the endoporus of intermediate piece 90 with can trackslipping, and tubular matrix 76 is then towards opposite
Direction extends in inner peripheral surface 84b in which can trackslip.Correspondingly, damping mechanism D is arranged on the circumferential both sides of the arm of force 55, to delay
Rotation of the guide 50 relative to the limiter element 180 circumferentially fixed with intermediate piece 90.Related set-up mode is quite analogous to Fig. 4 A
Shown in~4D.
Undoubtedly, the lift angle λ for rotating guiding mechanism G is still arranged to, 0 ＜ λ≤ζ.
The frictional connectors S3 course of work and frictional connectors S1 all fours, are repeated no more in this.
Example IV：The automatic control type spatial-wedging friction connector S4 of flexible engagement
Referring to Fig. 7, frictional connectors S4 is still the simple variant to frictional connectors S1.
First, between the axial direction of spring 100 and guide 50, restricted rotational movement can be made and can contradict to guide by being provided with
50 substantially a ring-shaped support member 220.The inner ring side of the support member 220, which is provided with, extends to guide 50 and intermediate piece with can trackslipping
Tubular matrix 226 in 90 endoporus, and tubular matrix 76 extends in inner peripheral surface 84b in which can then trackslip in the opposite direction.Its
In, support member 220 forms steerable stepless supporting mechanism SS with guide 50, spring 100 and limiter element 180.The branch
Support mechanism SS is that one is intermediate piece with support member 220 and has limiting angle ζ ' and ξ ' another space wedge mechanism, and it is most
The rotation guiding mechanism SG of two-way type is provided with goodly.Two groups of mechanism SG have all fours of complementary structure or are equal to
The tooth-like guiding tooth 62 and 232 of spiral of tooth 52 and 92 is oriented to, is separately positioned on support member 220 and as by the guide of support member
On 50 opposed facing annular end face, it is connected so that both rotate to guide to contradict.Wherein, it is oriented to the guiding of tooth 62 and 232
It is as defined above that the lift angle λ ' in face is less than ξ ', ζ ' and ξ '.
Most preferably it is provided with to drive and allowing guide 50 to move axially, on the outer peripheral face of support member 220 along entrance 82
Extend radially to the arm of force 222 of its outer rim.The arm of force 222 has circumferential appropriate intilted circumferential flank surface, can make this
Running clearance is most preferably formed between the arm of force 222 and two circumferential walls 85 of entrance 82, and ensures support member 220 with respect to limiter member
Part 180 has enough circumferential free degree ε ".Obviously, the circumferential free degree ε " is above-mentioned to the circumferential free degree with being quite analogous to
ε ' setting requirements, that is, should ensure that the work for rotating guiding mechanism SG rotates and do not hindered by circumferential wall 85.So,
, can be within circumferential free degree ε ", by supporting end face 224 and being oriented to tooth with respect to the rotatable support 220 of limiter element 180
232, while be compressed axially spring 100, on one side infinitely adjustable guiding part 50 by bearing height/pushed away from distance.The regulation
Can promote guide 50 by intermediate piece 90 and friction member 70 seamlessly first after elasticity rigidly compression/conflict in power transmission rubbing surface
The compression/conflict state is flexibly cancelled on 58, or after first rigidity, so as to forcibly establish or cancel frictional connection mechanism
Axial force it is closed contradict connection, and finally force space wedge mechanism reliably enter immediately in both circumferential directions wedge or
Solve wedge.Wherein, the crest top land of the guiding tooth 232 of support member 220, is limited by the axial direction of spacer pin 176, can be real to spring 100
The precommpression in similar embodiment one is applied, to ensure the axial direction of guide 50, intermediate piece 90, friction member 70 in circumferential recess 78
The free degree/gap is more than zero.
Secondly, damping mechanism D is arranged on the circumferential both sides of the arm of force 222, to delay support member 220 relative and guide 50
The rotation of circumferentially fixed limiter element 180.Set-up mode is similar to Fig. 4 A~4D.
Again, to realize flexible engagement, the lift angle λ and λ ' of two rotation guiding mechanisms G and SG in the present embodiment should be most
There is such parameter setting goodly, i.e. ζ ＜ λ≤ξ, and, 0 ＜ λ '≤ζ '.
Then, when frictional connectors S4 is as frictional connectors S1, during controllable slide device as such as motor vehicles,
For first axle 200 be coupled to engine setting, the frictional connectors S4 resilient engagement stage, traction friction mechanism F1 by because
Overload and skid naturally.And the friction torque of the skidding, it is relative that the rotation for causing to rotate in guiding mechanism SG is oriented to friction pair
Trackslip and climb.On the one hand, this is trackslipped infinitely compression spring 100 and climbed gradually to increase axial tension force, so that by
The slip-style friction torque that cumulative big frictional connectors S4 is transmitted, on the other hand, this, which trackslips and climbed, will also be damped mechanism D
Restriction, so that it is guaranteed that frictional connectors S4 engagement/wedging process has sufficient soft property.Other processes be similar to it is upper,
It is not repeated.
It is readily appreciated that, the present invention can be previously set and adjust dynamics and the time of the flexible engagement of frictional connectors, also
It is the changing rule that can be previously set and adjust its slip-style friction torque.Therefore, the characteristic be particularly advantageous to must have compared with
High engagement torque and the transmission for not allowing the automatic control type for joint impact occur to be frictionally engaged.For example, it is directed to traction elevator sedan-chair
The service braking of the jacking equipments such as railway carriage or compartment, escalator and/or the frictional connection application of automatic control type brake hard, and it is large-scale or
Heavy duty surmounts transmission application, the heavily loaded check application in mine field.
It is only the description and diagram that the present invention gives for its limited embodiments above, it is a certain degree of special to have
Property, it is understood that, mentioned embodiment and accompanying drawing are all merely illustrative, rather than the limitation present invention and its guarantor
Scope is protected, various change, equivalent, exchange and the change of member position or structure for carrying out them, will all be considered as not taking off
Leave the spirit and scope of present inventive concept.
