Embodiment
Below in conjunction with drawings and Examples, the present invention is further elaborated.
Embodiment one: as shown in Figure 1, a kind of castellated free wheel device, it is characterized in that: comprise the torque wheel 1 being connected with interior axle 8 and be placed in the expanding wheel 2 on interior axle 8, the keyway 7 of described torque wheel 1 matches with the spline 9 of Inner axle 8, the counterface of described torque wheel 1 and expanding wheel 2 is provided with mutual chimeric right-angled trapezium tooth 6(but is not limited to this, it can also be the tooth of other types, for example isosceles trapezoid tooth, triangle tooth or irregular quadrilateral tooth etc.), between described torque wheel 1 and expanding wheel 2, be provided with the preloading spring 4 that makes expanding wheel 2 have relative rotation trend with respect to torque wheel 1, but be not limited to this.Described torque wheel 1 and expanding wheel 2 are arranged in shell 5, between described torque wheel 1 and shell 5 and between expanding wheel 2 and shell 5, are equipped with a slice outside friction disc 3, and described outside friction disc 3 is placed on interior axle 8 and with shell 5 and is connected.Described shell 5 is made up of lid and housing, and described lid is locked on housing through screw 51, but is not limited to this.If the Inner axle 8 being connected with torque wheel 1 is power intakes, the shell 5 being connected with two outside friction discs 3 is clutch ends, and power intake and clutch end can exchange certainly.
Embodiment one working principle is as follows: see along the direction of arrow in Fig. 1, first torque wheel 1 imposes on the pressure of expanding wheel 2 by preloading spring 4, make expanding wheel 2 have the trend rotating counterclockwise with respect to torque wheel 1, and under the effect of torque wheel 1 and expanding wheel 2 chimeric surfaces torque wheel 1 and expanding wheel 2 have in the axial direction mutually away from trend, make torque wheel 1 have an axial pressure and initial frictional, expanding wheel 2 to have an axial pressure and initial frictional to its contiguous outside friction disc 3 to its contiguous outside friction disc 3.In the time that the Inner axle 8 being connected with torque wheel 1 is rotated counterclockwise with respect to the shell 5 being connected with two outside friction discs 3, torque wheel 1 overcomes initial frictional and is rotated counterclockwise with respect to two outside friction discs 3, expanding wheel 2 overcomes initial frictional and is also rotated counterclockwise under the effect of preloading spring 4, and now Inner axle 8 and shell 5 keep rotating freely or state of rest separately.In the time that above-mentioned torque wheel 1 overcomes initial frictional and turns clockwise with respect to two outside friction discs 3, under the effect of initial frictional, expanding wheel 2 outside friction disc 3 adjacent thereto keeps relatively static, now torque wheel 1 also turns clockwise with respect to expanding wheel 2, mutual slip between torque wheel 1 and expanding wheel 2 chimeric surfaces impel torque wheel 1 and expanding wheel 2 in the axial direction mutually away from but the chimeric surface of the two still keep in touch, and then the surface of contact of torque wheel 1 outside friction disc 3 adjacent thereto, the surface of contact of expanding wheel 2 outside friction disc 3 adjacent thereto torque wheel 1 and expanding wheel 2 mutually away from axial pressure under mutually compress, now Inner axle 8 is integrated with shell 5 lockings.When above-mentioned torque wheel 1 is transformed into while being rotated counterclockwise from dextrorotation with respect to two outside friction discs 3, the surface of contact of the chimeric surface of torque wheel 1 and expanding wheel 2, the surface of contact of expanding wheel 2 outside friction disc 3 adjacent thereto, torque wheel 1 outside friction disc 3 adjacent thereto is because of the release that reduces of pressure, and Inner axle 8 and shell 5 return to rotating freely or state of rest separately again.
But, all there is frictional force and resiliently deformable in any material, when the torque wheel 1 in above-mentioned castellated free wheel device is transformed into while being rotated counterclockwise from dextrorotation with respect to two outside friction discs 3, on the face that the elastically-deformable stored energy that this castellated free wheel device produces during by transmitting torque contacts between two at torque wheel 1, expanding wheel 2, outside friction disc 3, so need the very large torque of expense just can make this castellated free wheel device release.In order to allow the release of this castellated free wheel device become simple and to reduce wear, there is following optimal design.
Embodiment two: as shown in Fig. 2 ~ 4, this castellated free wheel device is set up some members on embodiment one basis, specific as follows: on each facing of described torque wheel 1, be respectively equipped with tapered roller assembly 11, described tapered roller assembly 11 is by multiple tapered rollers camber in parallel; In order to make tapered roller assembly 11 be difficult for skew, between right-angled trapezium tooth 6 end side surface of described tapered roller assembly 11 and torque wheel 1, be provided with balance spring 111, but be not limited to this.Certainly, described tapered roller assembly 11 also can be arranged on each facing of expanding wheel 2, and described balance spring 111 also can be connected in right-angled trapezium tooth 6 end side surface of expanding wheel 2.Between described torque wheel 1 outside friction disc 3 adjacent thereto, be provided with tapered roller circle 12 and buffering inner attrition piece 13, described tapered roller circle 12 is by multiple tapered rollers and is unified into ring, described buffering inner attrition piece 13 can rotate freely several angle around Inner axle 8, be conducive to the release of castellated free wheel device, but be not limited to this.In order to reduce further surface friction drag and energy consumption, the inner side of described torque wheel 1 is provided with centrifugal-block 16, and described expanding wheel 2 is provided with centrifugal-block locking slot 161, but is not limited to this.
Embodiment two working principle is as follows: see along the direction of arrow in Fig. 2, this castellated free wheel device Inner axle 8 and shell 5 keep separately rotate freely or principle and embodiment one that state of rest and locking are integrated basic identical: under torque wheel 1 and the interaction of expanding wheel 2 chimeric surfaces and the combination of preloading spring 4, producing axial pressure and initial frictional, is that main rubbing surface becomes the surface of contact of expanding wheel 2 outside friction disc 3 adjacent thereto and cushions the surface of contact of inner attrition piece 13 outside friction disc 3 adjacent thereto.Lock in solution: when the Inner axle 8 being connected with torque wheel 1 is transformed into while being rotated counterclockwise from dextrorotation with respect to the shell 5 being connected with two outside friction discs 3, torque wheel 1 overcomes initial frictional and is transformed into and is rotated counterclockwise from dextrorotation with respect to two outside friction discs 3, because buffering inner attrition piece 13 can rotate freely several angle around Inner axle 8, first the torque that Inner axle 8 rotates counterclockwise with respect to shell 5 only acts on torque wheel 1, and two end faces of torque wheel 1 have the pure rolling effect of tapered roller to make torque wheel 1 be easy to be rotated counterclockwise and release with respect to outside friction disc 3, rotate together with torque wheel 1 by interior axle 8 again when cushioning inner attrition piece 13 after release.Certainly, can omit buffering inner attrition piece 13, allow the direct outside friction disc 3 adjacent thereto of tapered roller circle 12 contact, combination can reduce the axial dimension of this castellated free wheel device like this, but it can carry torque meeting and diminishes.When shell 5 is static or low speed rotation, and Inner axle 8 is while being rotated counterclockwise at a high speed, the axial thrust load of centrifugal-block 16 centrifugal actions on torque wheel 1 impels expanding wheel 2 and torque wheel 1 overcome the elastic force of preloading spring 4 and are mutually pressed together, now expanding wheel 2 outside friction disc 3 adjacent thereto, between buffering inner attrition piece 13 outside friction disc 3 adjacent thereto, all there is no the initial frictional producing because of axial pressure, reduce the relative rotational resistance of Inner axle 8 with shell 5, certainly under the effect of centrifugal-block 16, the rotating speed of torque wheel 1 and buffering inner attrition piece 13 is not limited to this with turning to.
Embodiment three: as shown in Fig. 5 ~ 6, embodiment two tapered roller assembly 11 and tapered roller circle 12 are replaced to oil storage tank 17 by this castellated free wheel device, and oil storage tank 17 has the effect that reduces surface friction drag equally.Simultaneously, this castellated free wheel device offers respectively afterburning lever slot 18 on torque wheel 1 and expanding wheel 2, and between torque wheel 1 and expanding wheel 2, be provided with the afterburning lever 19 being inserted in afterburning lever slot 18, this castellated free wheel device has additional keep-spring 20 in torque wheel 1 keyway 7, but is not limited to this.Certainly, tapered roller assembly 11, afterburning lever 19, oil storage tank 17 these threes can independently exist, also tapered roller assembly 11 and afterburning lever 19 can be used in combination or afterburning lever 19 is used in combination with oil storage tank 17, but generally tapered roller assembly 11 and oil storage tank 17 are not used in combination, using effect is bad like this.
Embodiment three working principle is as follows: see along the direction of arrow in Fig. 5.Its most of principle with implement one, implement two similar, under torque wheel 1 and the interaction of expanding wheel 2 chimeric surfaces and the combination of preloading spring 4, produce axial pressure and initial frictional, main rubbing surface is the surface of contact of expanding wheel 2 outside friction disc 3 adjacent thereto and the surface of contact of buffering inner attrition piece 13 outside friction disc 3 adjacent thereto.In the time that the Inner axle 8 being connected with torque wheel 1 is rotated counterclockwise with respect to the shell 5 being connected with two outside friction discs 3, torque wheel 1 overcomes initial frictional and is rotated counterclockwise with respect to two outside friction discs 3, expanding wheel 2 overcomes initial frictional and is also rotated counterclockwise under the effect of preloading spring 4, and now Inner axle 8 and shell 5 keep rotating freely or state of rest separately.In the time that above-mentioned torque wheel 1 turns clockwise with respect to outside friction disc 3, under the effect of making a concerted effort of right-angled trapezium tooth 6 axial pressures of preloading spring 4 and tabling, torque wheel 1 all compresses with buffering inner attrition piece 13, buffering inner attrition piece 13 outside friction disc 3 adjacent thereto, expanding wheel 2 outside friction disc 3 adjacent thereto mutually with chimeric surface, the torque wheel 1 of expanding wheel 2, and Inner axle 8 and shell 5 lockings are integrated.Now torque wheel 1 is very large with the pressure of the surface of contact of buffering inner attrition piece 13 with chimeric surface, the torque wheel 1 of expanding wheel 2, and the elastic strain of material is pressed into its lip-deep parts of lubricating oil in oil storage tank 17 and is pressurised into extreme pressure lubricant.When above-mentioned torque wheel 1 is transformed into while being rotated counterclockwise (because buffering inner attrition piece 13 can rotate freely several angle around Inner axle 8 from dextrorotation with respect to outside friction disc 3, first the torque that Inner axle 8 is rotated counterclockwise with respect to shell 5 acts on torque wheel 1), the chimeric surface of torque wheel 1 and expanding wheel 2, torque wheel 1 makes this surface of extreme pressure lubricant part re-lubrication in oil storage tank 17 with the reduction of the surface of contact pressure of buffering inner attrition piece 13, reduce this lip-deep frictional force, reduce the resistance that torque wheel 1 is rotated counterclockwise, allow the release of castellated free wheel device become light.Certainly, also can omit buffering inner attrition piece 13, allow torque wheel 1 directly contact with outside friction disc 3, and be provided with oil storage tank 17 on the surface of contact of outside friction disc 3 and torque wheel 1, but be not limited to this.Although this structure can reduce the axial dimension of castellated free wheel device, it can carry torque meeting and diminish.
With reference to figure 5 ~ 6, torque wheel 1 can rotate a certain angle with respect to Inner axle 8, but due to the effect of keep-spring 20, torque wheel 1 is pressed in the counter clockwise direction of Inner axle 8.When Inner axle 8(drives torque wheel 1) become while turning clockwise from counterclockwise (free state) rotation with respect to the shell 5 being connected with outside friction disc 3, torque wheel 1 almost synchronously turns clockwise Inner axle 8 and shell 5 lockings is integrated with Inner axle 8 immediately under the effect of keep-spring 20, has improved speed of response.When above-mentioned Inner axle 8 becomes while being rotated counterclockwise from clockwise direction rotation with respect to shell 5, because torque wheel 1 is integrated with outside friction disc 3 lockings by expanding wheel 2 and buffering inner attrition piece 13, Inner axle 8 is applied to torque on afterburning lever 19 in the process of elastic force that overcomes keep-spring 20, the torques that amplify by afterburning lever 19 handles are on torque wheel 1 and expanding wheel 2, for separating of the resistance producing on the chimeric surface of torque wheel 1 and expanding wheel 2 because of material deformation, add the effect of oil storage tank 17 interior lubricant oil, make the release of this castellated free wheel device more easy.Centrifugal-block 16 principles of this castellated free wheel device are identical with centrifugal-block 16 principles in embodiment two.
Especially, it should be noted that, the shell 5 that what discuss in the various embodiments described above is the Inner axle 8 that is connected with torque wheel 1, be connected with outside friction disc 3 is respectively input end, the output terminal of power, and both can freely exchange; Certainly in actual applications, also can allow torque wheel 1 be connected with shell 5, the shell 5 being connected with outside friction disc 3 with torque wheel 1, the Inner axle 8 being connected with inner attrition piece 14 and buffering inner attrition piece 13 are respectively input end, the output terminal of power, and both can freely exchange.
Embodiment four: as shown in Figure 7, from left to right be disposed with torque wheel 1, tapered roller assembly 11, expanding wheel 2, inner attrition piece 14, tapered roller circle 12, buffering inner attrition piece 13, outside friction disc 3, wherein between torque wheel 1 and expanding wheel 2, be provided with preloading spring 4, inner attrition piece 14 is connected with Inner axle 8, and buffering inner attrition piece 13 can freely turn an angle around Inner axle 8.For tapered roller assembly 11 is difficult for skew, between right-angled trapezium tooth 6 end side surface of tapered roller assembly 11 and torque wheel 1, be provided with balance spring 111, but be not limited to this.In order to reduce further surface friction drag and energy consumption, the inner side of described torque wheel 1 is provided with centrifugal-block 16, and described expanding wheel 2 is provided with centrifugal-block locking slot 161, but is not limited to this.
Embodiment four working principle is as follows: see along the direction of arrow in Fig. 7, embodiment four and embodiment's two principle is substantially the same, be all to allow the release of this castellated free wheel device become easily by the pure rolling effect of tapered roller assembly 11 and tapered roller circle 12, main rubbing surface is expanding wheel 2 and the surface of contact of inner attrition piece 14 and the surface of contact of buffering inner attrition piece 13 and outside friction disc 3.Under torque wheel 1 and the chimeric surface of expanding wheel 2 and the effect of preloading spring 4, on the surface of contact of this castellated free wheel device any two parts that contact in the axial direction, all produce axial pressure and initial frictional.In the time that the shell 5 being connected with outside friction disc 3 with torque wheel 1 is rotated counterclockwise with respect to the Inner axle 8 being connected with buffering inner attrition piece 13 with inner attrition piece 14, torque wheel 1 is rotated counterclockwise with respect to inner attrition piece 14, expanding wheel 2 is also rotated counterclockwise with respect to inner attrition piece 14, and now Inner axle 8 and shell 5 keep rotating freely or state of rest separately.In the time that above-mentioned torque wheel 1 turns clockwise with respect to inner attrition piece 14, expanding wheel 2 keeps relative static with inner attrition piece 14 under the effect of initial frictional, under the force action of preloading spring 4 elastic force and chimeric surface axial pressure, the chimeric surface of torque wheel 1 and expanding wheel 2, buffering inner attrition piece 13 and outside friction disc 3, expanding wheel 2 and inner attrition piece 14 all compress mutually, and whole castellated free wheel device locking is integrated.When above-mentioned torque wheel 1 is transformed into while being rotated counterclockwise from dextrorotation with respect to inner attrition piece 14, because buffering inner attrition piece 13 can rotate freely several angle around interior axle 8, the now torque of Inner axle 8 only acts on inner attrition piece 14, and then under the effect of tapered roller assembly 11 and tapered roller circle 12, inner attrition piece 14 can drive expanding wheel 2 with respect to torque wheel 1 dextrorotation then release than being easier to by frictional force.Certainly, also can omit buffering inner attrition piece 13, allow tapered roller circle 12 directly contact with outside friction disc 3, although can reduce like this axial dimension of castellated free wheel device, it can carry torque meeting and diminish.When inner attrition piece 14 with buffering inner attrition piece 13 is static or low speed rotation, and torque wheel 1 is while being rotated counterclockwise at a high speed, on torque wheel 1, centrifugal-block 16(is with reference to Fig. 4) the axial thrust load of centrifugal action impel expanding wheel 2 and torque wheel 1 overcome preloading spring 4 elastic force and are mutually pressed together, now expanding wheel 2 and inner attrition piece 14, between buffering inner attrition piece 13 and outside friction disc 3, all there is no the initial frictional being produced by axial pressure, reduce the relative rotational resistance of input end with output terminal, certainly under the effect of centrifugal-block 16, the rotating speed of torque wheel 1 and inner attrition piece 14 is not limited to this with turning to.
Embodiment five: as shown in Figure 8, embodiment five just changes the tapered roller assembly 11 in embodiment four and tapered roller circle 12 into oil storage tank 17, and its working principle can be with reference to embodiment three and embodiment four.Certainly, the buffering inner attrition piece 13 in embodiment five also can omit.
Embodiment six: as shown in Figure 9, embodiment six structure and embodiment four are basic identical, just the right-angled trapezium tooth 6 of tabling on torque wheel 1 and expanding wheel 2 is become to isosceles trapezoid tooth 21, then preloading spring 4 use controlling rods 22, torsion spring 23 and gear train 24 are replaced, also can be with controls such as solenoid valves, but be not limited to this.Wherein one end of torsion spring 23 is connected with controlling rod 22, the other end is connected with gear train 24, and its effect is the direction that can control this castellated free wheel device and will carry torque.
Embodiment six working principle is as follows: in the time seeing above Fig. 9, controlling rod 22 is fixing rotating counterclockwise, now the elastic force of torsion spring 23 acts on expanding wheel 2 by gear train 24 and makes expanding wheel 2 have the trend being rotated counterclockwise with respect to torque wheel 1 when the direction of arrow is seen, is locking state, is free state while turning clockwise while being now rotated counterclockwise with respect to the shell 5 being connected with outside friction disc 3 with torque wheel 1 with reference to embodiment four the known Inner axle 8 being connected with buffering inner attrition piece 13 with inner attrition piece 14 of working principle.In the time seeing above Fig. 9, controlling rod 22 is fixing clockwise rotating, now the elastic force of torsion spring 23 acts on expanding wheel 2 by gear train 24 and makes expanding wheel 2 have the trend turning clockwise with respect to torque wheel 1 when the direction of arrow is seen, is locking state, is free state while being rotated counterclockwise while now turning clockwise with respect to the shell 5 being connected with outside friction disc 3 with torque wheel 1 with reference to embodiment four the known Inner axle 8 being connected with buffering inner attrition piece 13 with inner attrition piece 14 of working principle.
Especially, it should be noted that, above-mentioned all embodiments all can also adopt following mode of structure: as shown in figure 10, in order to increase carried of the torque of this castellated free wheel device, on the basis of the various embodiments described above, on it is axial, be alternately placed with buffering inner attrition piece 13 and outside friction disc 3 again, wherein, in order to make to cushion keeping strokes of inner attrition piece 13, on buffering inner attrition piece 13, be provided with synchronous hole 25, synchronously sell in the 26 synchronous holes 25 of insertion.Working principle is as follows: with reference to embodiment three working principle, see along the direction of arrow in Figure 10, in the time that the torque wheel 1 being connected with Inner axle 8 turns clockwise with respect to the multi-disc outside friction disc 3 being connected with shell 5, being free state, is lockup state while being rotated counterclockwise.When above-mentioned torque wheel 1 becomes the characteristic that can rotate freely around interior axle 8 several angle while turning clockwise due to buffering inner attrition piece 13 with respect to multi-disc outside friction disc 3 from being rotated counterclockwise, make Inner axle 8 first torque independent role on torque wheel 1, the lubrication of adding oil storage tank 17 becomes than being easier to its release.And owing to being arranged alternately in the axial direction multilayer buffering inner attrition piece 13 and outside friction disc 3, its torque that can carry is improved a lot.
Especially, it should be noted that, in the various embodiments described above, the Main Function of Inner axle 8 is to transmit or receive to have the torque wheel 1 being connected with Inner axle 8, the torque that cushions inner attrition piece 13, inner attrition piece 14, in this castellated free wheel device, Inner axle 8 is not necessary parts, and this castellated free wheel device can carry Inner axle 8 or provide Inner axle 8 by user; Certainly, Inner axle 8 can replace with other parts, as long as can transmit or receive the torque that has parts are connected therewith torque wheel 1, cushions inner attrition piece 13, inner attrition piece 14.The Main Function of the various embodiments described above housing 5 has 3 points: (1) provides a working environment that is relatively conducive to this castellated free wheel device operation, to improve its working life etc.; (2) torque wheel 1 being connected with shell 5, the spinning movement of one or more outside friction disc 3 are consistent, transmit or receive simultaneously the torque of torque wheel 1 and one or more outside friction disc 3; (3) axial length that limits this castellated free wheel device is in OK range, to guarantee that this castellated free wheel device normally works.Due to this castellated free wheel device as long as contact by torque wheel 1, with expanding wheel 2 and have the friction plate of initial frictional (what wherein contact with expanding wheel 2 in the time that torque wheel 1 is connected with Inner axle 8 is outside friction disc 3, and now torque wheel 1 and outside friction disc 3 are respectively input end and the output terminal that can exchange; What in the time that torque wheel 1 is connected with shell 5, contact with expanding wheel 2 is inner attrition piece 14, now torque wheel 1 and inner attrition piece 14 are respectively input end and the output terminal that can exchange) be limited in the axial direction in a suitable length and just can work, therefore shell 5 can be replaced by other parts, as long as can meet the operating conditions of this castellated free wheel device.
Especially, it should be noted that, being connected of axle 8 and torque wheel 1, shell 5 being not limited to spline with being connected of outside friction disc 3 etc. and linking in this castellated free wheel device, as long as can meet foregoing job requirement.In the castellated free wheel device with tapered roller assembly 11, the tapered roller assembly 11 on tapered roller assembly 11 or each tooth on part tooth can be linked to be to an entirety, but be not limited to this, as shown in figure 11.Preloading spring 4 once also will be discussed here, under the effect of preloading spring 4, expanding wheel 2 not only has counterrotating trend with respect to torque wheel 1, on the face that also makes to contact between two between torque wheel 1, expanding wheel 2, friction plate (can be outside friction disc 3, inner attrition piece 14 or buffering inner attrition piece 13), produce axial pressure and initial frictional (pre-locking effect) under the effect of torque wheel 1 and expanding wheel 2 chimeric surfaces, in the time that input end meets locking condition with the relative rotation of output terminal, can lock rapidly.Analysis by is above known also can make this castellated free wheel device produce the object of locking when preloading spring 4 use torsion springs 23 and controlling rod 22, gear train 24 are replaced.Therefore, preloading spring 4 can replace with other parts, has an initial frictional as long as can allow on surface of contact between expanding wheel 2 and friction plate adjacent thereto.
