Described problem is by a kind of feature with claim 1 for activating the parking of the parking lock in motor vehicles Lock module solves.Dependent claims are related to advantageous embodiment of the invention.

It is a kind of for activating the parking lock module of the parking lock in motor vehicles in the case where, which has Shell accommodates actuating mechanism in the housing, which is hingedly attached to actuating component, at the end far from actuating mechanism Portion, the actuating component have the actuating element with conical surface portion, which can be with tapered guide element Contact, the tapered guide element are fixed relative to shell and in the form of metal profiles, so that producing by actuating mechanism During the movement of raw actuating component, conical surface portion is supported on along the longitudinal direction on the support section of support plate, and Here, by the deflection of actuating component, the movement of actuating element in a lateral direction is realized, to activate parking lock；According to this hair Bright, the shell is molded of plastic material and support plate is integrated in the housing so that the support section of support plate in order to cause Dynamic element contacts and protrudes past the plastic material of shell.

In order to be mass produced, plastics are provided as the material of shell and advantageously allow for coming using injection molding process first Manufacture shell.Here it is possible to the attachment area for being used to support plate easily be collectively formed, without finishing to shell. It may be thus possible, for example, to form the bag for receiving support plate with positive lock mode, the shape of this bag by the core in injection mold Shape and position allow support plate relative to shell and relative to the essence that be contained in function element therein (actuating mechanism etc.) Determine position.In order to which support plate to be fixed on shell or in shell, positive locking measure equally can easily be collectively formed, such as Clamp type or buckle-type connection, are configured to engagement and are connected to behind the support plate of bag, and the support plate is maintained in bag. However, support plate can also be simply bonded in such shell recess portion or bag.

In the especially preferred embodiments, support plate is integrated in the housing and the plastic overmold with shell.Cause This, support plate is directly kept in the housing or on shell with positive lock mode.After the injection molding of shell, therefore this In the case of, support plate is connected to shell, does not need further assembling steps；On the contrary, in this case, shell and support The component of plate may have been formed into a component of injection mold.If support plate accordingly acts as the insertion section of injection mold Part, then this extra high precision that positioning of the support plate in the housing or on shell is realized in a manner of being very easy to reproduce, special It is not without further alignment or positioning step.

Since support plate in the housing integrated is realized in any case, so that the support section of support plate is prominent super The plastic material for crossing shell allows actuating element directly against support plate, although shell is formed by plastics, at these Do not have to increase the risk worn on component, at these components, during the operation of parking lock module, under force directly It contacts and there is relative motion in the contact areas.If support plate preferably injection molding is the insertion in the plastics of shell Component, then the support section of support plate can also be used for advantageously in injection mold relative to shell positioning support plate, because Support section will not be covered by the plastics of shell.Therefore, the support section of support plate herein for the manufacture of parking lock module and Operation all plays an important role.

As a result, by means of the design according to the present invention of parking lock module, compared with the common prior art, and by shell Manufacture and the relevant expense of assembling with the unit of support plate composition significantly reduce.It can save for generating the convex of precise match Any machining or assembling steps of edge connection, press-fitting connection and/or threaded connection.Similarly, since parking lock module is opposite There is rather low weight in previously known parking lock module, without the significant damage in any function in terms of mechanical strength Lose, therefore it is also seen that the shell formed by plastics major advantage.Finally, this is also to the consumption of motor vehicle and carbon dioxide Balance generates positive influence.

The support section of support plate, which can substantially be made, has plane or more side surface portions, such as observes in cross-section When in stop element shape surface portion, contacted for the conical surface portion with actuating element.Especially with regard to activating The self-centering support clearly limited between element and support plate, in those cases it may however be preferred to, if the support section of support plate has Partial cylindrical surface part, the conical surface portion of actuating element can be placed in adjacent with the partial cylindrical surface part.

Here, the radius of the partial cylindrical surface part of the support section of support plate, which preferably forms, is slightly over actuating The maximum radius of the conical surface portion of element.Therefore firstly, advantageously avoiding the contact between actuating element and support plate Point load in region.Secondly, advantageous situation is in parking lock engagement, linear between actuating element and support plate or Region contact is extended, so that there is also Maximum Contact faces on the support section of support plate in the case where maximum, force load Product.

In principle, the shell of only parking lock module can have for parking lock module to be mounted in motor vehicles Fastener hole.On the contrary, however, it is preferred that embodiment be wherein support plate equipped with for parking lock module to be fastened on motor vehicles In fastener hole.Therefore, the power in support plate is introduced by actuating element and does not need plastic casing by parking lock module It accommodates and is supported relative to motor vehicles, so that the shell of parking lock module is needed not be for this purpose and designed.In the improvement side In case, there is the direct force flow of the installation site of the parking lock module in from support plate to motor vehicles.

Alternatively or additionally, in order to which parking lock module to be fastened in motor vehicles, the shell of parking lock module Can be at the position being spaced apart with support plate equipped at least one fastener hole, which is lined with stop sleeve, the support Sleeve is fastened in the housing and the plastic overmold with shell.This advantageously contributes to for good and all prevent shell and support Relative motion between plate.Situation is especially true, because of sedimentation of the metal stop sleeve to the threaded connection at fastener hole (settling) behavior has positive influence, this is because the screw prestressing force of screw connection sleeve part can in an assembling process It is kept by ground.Moreover, during the injection molding of shell, the shell realized in the region of fastener hole by stop sleeve plus It can inexpensively be collectively formed by force, wherein stop sleeve is as the insertion part in injection mold.

In addition, if in the preferred embodiment of parking lock module, other than the measure of fastening parking lock module, setting two A centring pin, the two centring pins are fixedly connected on shell, and by means of the centring pin, and parking lock module can be relative to Parking lock positioning additionally aids most accurate possible positioning and parking lock module of the parking lock module relative to parking lock in machine Simple installation in motor-car.However, the positioning as the substitution to this, for parking lock module relative to parking locking device It is positioned with angle, shell can also be equipped with the receiver hole for centring pin on the rolling stock to be arranged.

In an advantageous embodiment, one in two centring pins can be fixed on the hole being formed in support plate here In, and another in two centring pins forms one with shell.About being equally conceivable and in the housing or on shell Tool has the modification there are two centring pin or hole there are two centring pin or hole or in support plate or in support plate, the former is preferred real It applies example to be advantageous, because the additional positioning of shell and support plate relative to each other is realized simultaneously at its.

In order on parking lock module or it is middle offer or generation parking lock engagement and be detached from needed for actuating power, substantially There are various possibilities.For example, engagement and/or disengaging can come by means of the electric actuator in the actuating mechanism of parking lock module It executes.It is also contemplated that with the combination that activates manually, such as by means of Bowden cable, for the actuating as parking lock module The parking lock of the component part of mechanism engages or disengages.However, it is particularly preferred to the embodiment of parking lock module, wherein causing Motivation structure has piston, which is pre-loaded to latched position by piston spring on locking direction with spring force, wherein institute Stating piston can selectively be fixed by stop device relative to shell, and wherein piston can be by means of pressure chamber edge and locking side Bear pressure load to opposite unlocking direction, with when stop device is released in opposite with the spring force of piston spring Unlocked position.On the one hand, during pressure medium such as hydraulic fluid usually can be used as motor vehicles operation under any circumstance Effective actuated media, and therefore can also be used for the disengaging of parking lock.On the other hand, the piston spring along locking direction effect mentions For the advantages of be that it can store power, therefore allow to engage parking in the absence of external forces in case of emergency Lock.By means of stop device, ensure reliably to keep the corresponding actuating state of parking lock module herein.

In order to form piston, however, it would be possible to use metal material, especially iron-bearing materials and non-ferrous metal, such as aluminium base Alloy.Especially for the production of low weight and cheap and simple as mass produced components, in those cases it may however be preferred to, piston also shape As plastic injection piece.

Here, in the especially preferred embodiments, in order to engage stop device, piston can be reinforced metallic sheath ring set Cylinder, the metal collar sleeve are embedded in piston plastic material.In addition to there is relatively low work in the position of mechanical especially high load Fill in weight and (however) low-level abrasion the advantages of except, the fillet for stop device that is formed by lantern ring sleeve because This can be positioned relative to piston with accurate and reproducible exact way, without mounting cost.

In another embodiment of the advantageous parking lock module of use aspect about plastics, it can be stated that stop device Actuator flange be mounted on the shell of parking lock module and be held in place by screw, wherein shell is equipped with for connecing The screw-thread bush of screw is received, which is embedded in shell and the plastic overmold with shell.In order to fasten actuating The reinforcement of device, the shell realized by means of screw-thread bush can also be inexpensively collectively formed during the injection molding of shell, then Secondary (similarly) and screw-thread bush are together as the insertion part in injection mold.

It is particularly preferred that piston spring is bonded on piston by thrust piece, thrust piece is preferably (especially with regard to honest and clean Valence manufacture) it is made of plastics and can be relative to piston in the unlock opposite with the spring force of piston spring by means of actuating component It is moved on direction.With the piston spring being equally conceivable in directly engaging on piston or consolidating between thrust piece and piston Fixed connection is compared, and major advantage here is, the misuse power acted in actuating component on unlocking direction cannot be transmitted to Piston, but by being passed forward to from the thrust piece lifted on piston in piston spring and " being siphoned away " there.Therefore, living Plug spring is not only used as the energy accumulator of the emergency operation for parking lock module, but also is causing simultaneously together with thrust piece Dynamic component be not caused by piston along unlocking direction move in the case where separate actuating component with piston.As a result, solving Lock side, which is acting upwardly on impact in actuating component etc., to cause any damage to piston and adjacent component.

In addition, thrust piece preferably has guidance extension on the side far from actuating component, served as a contrast by means of guidance Set is guided, and guide bushing is preferably equally made of plastics and is fastened on shell again.This advantageously produces thrust piece Long length of lead, and avoid thrust piece relative to the inclination of shell and may relevant machine during thrust piece displacement Tool moving mass.In a preferred embodiment, guide bushing is attached to shell in this case through bayonet connection.It is served as a contrast with guidance It covers and is compared the threaded connection between shell, welded connecting or bonding connection (such as it is also contemplated that), this shape cooperation connects Connect very easy assembling.In addition, about the quick connection between equally possible in principle guide bushing and shell, the card Mouth connection this have the advantage that, it is not necessary to provide additional axial assembling stroke so that connecting element is engaged with each other, this has in turn Conducive to short structure length.

Finally, for the ventilation and degasification of the inner space of shell during piston moves in the interior space, shell Side wall can be equipped with one or more degasification plates.Rather, it is preferred to which guide bushing is equipped with since the end far from piston There is the opening that ventilation and/or degasification are carried out for the inner space to shell, this is not only easy to be formed, such as by serving as a contrast with guidance Set injection molding is " being removed from the molds " plastic components, without reprocessing, and further minimizes opening and is not expected The risk of ground covering.

In Fig. 9, the right hand end in secondary piston part 96 is similarly formed as plastic injection to engage stop device 46 The piston 40 of part is reinforced by metal collar sleeve 116 on excircle, and metal collar sleeve 116 is embedded in the plastics material of piston 40 In material.Covering ring sleeve 116 has outer profile, which allows piston 40 to lock relative to shell 30 by means of stop device 46 In the latched position or unlocked position of piston 40.For this purpose, stop device 46 has made of metal lever 118, which can It is movably contained in the brake bar notch 120 of shell 30, which is laterally extended relative to central axis M.More Specifically, brake bar 118 can pivot (referring to the double-head arrow in Fig. 6) around metal brake lever pin 122, the metal brake lever pin 122, which are parallel to central axis M, extends and in the plastic material of heat insertion shell 30 to the two sides of brake bar notch 120.

Best seen in from Fig. 6, brake bar 118 surrounds brake bar by means of brake-rod spring 124 in Fig. 6 122 counter clockwise direction of pin is pre-loaded to the application position on the set ring sleeve 116 of piston 40.Be formed as the system of spiral compression spring Lever spring 124 is guided in the cylindrical receiver protrusion 126 being integrally formed with shell 30, and is bonded on brake bar 118 Activation projection 128 on.In order to selectively moved brake bar 118 against brake-rod spring 124 spring force from its retarder location It sets into the non-braking position (this allows piston 40 to move along central axis M) far from the set ring sleeve 116 on piston 40, stop The tool of device 46 is there are two the unlocking mechanism that can activate independently of one another, the unlocking mechanism that can specifically electrically activate and can be hydraulic The unlocking mechanism of activation.

Stop device 46 has by the unlocking mechanism that connection terminal 130 can electrically activate shown in Fig. 2,4 to 6 and 9 Electromagnetic actuators 132 (stroke magnet), flange is mounted on the shell 30 of parking lock module 10 and passes through screw from below 134 are held in place.For this purpose, if the shell 30 of Fig. 2 and 4 is equipped with the screw-thread bush 136 for receiving screw 134, screw thread lining Set with the plastic overmold of shell 30 by being embedded in shell 30.Electromagnetic actuators 132 have pin-shaped actuating end 138, the cause It moved end 138 can be according to the electrical activation of actuator 132 and corresponding to the double-head arrow axial movement in Fig. 6 and 9 and itself and brake bar 118 promotion end 140 engages, which is arc in Fig. 6.

It will be clear to someone skilled in the art that by the appropriate electric excitations of electromagnetic actuators 132, brake bar 118 can be by In the actuating end 138 promoted on end 140 for being bonded on brake bar 118 of actuator 132 against the brake-rod spring 124 in Fig. 6 Spring force around brake rod pin 122 clockwise promoted and pivot so that brake bar 118 is released from the set ring sleeve 116 of piston 40 It puts.

By means of can hydraulic activation unlocking mechanism, brake bar 118 can correspondingly pivot around brake rod pin 122, for this purpose, As shown in fig. 6, this can hydraulic activation unlocking mechanism have round metal pin 142, on excircle have slip ring 144, can It is movably contained in the cylinder-bore 146 of shell 30.For the hydraulic load of cylinder-bore 146 and cylinder pin 142, such as Fig. 4 and 8 Shown in shell 30 downside have another pressure port 148, be formed on shell 30, to be parallel to pressure end Mouth 110 is arranged.Another pressure port is connected to by another interface channel 150 and cylinder-bore 146 (referring to fig. 4 with 6 to 8), The interface channel 150 is formed in shell 30 and obliquely extends relative to central axis M.The inner end of interface channel 150 with Cylinder-bore 146 intersects, as shown in Figure 6.In its another outer end, as illustrated in figures 1 and 7, interface channel 150 passes through 152 phase of plastic plug Ambient enviroment is sealed shut, plastic plug 152 is ultrasonically welded on shell 30.

To those skilled in the art, again it is clear that right by pressure port 148 and interface channel 150 In the case that cylinder pin 142 carries out hydraulic loaded, the cylinder pin 142 in Fig. 6 is mentioned in cylinder-bore 146 corresponding to double-head arrow It rises, wherein straight pin 142 is resisted against the promotion protrusion 154 of the lug-shaped of brake bar 118 with its end for protruding past shell 30 On.Here, brake bar 118 is lifted, and suitable around brake rod pin 122 against the spring force of brake-rod spring 124 in Fig. 6 Hour hands pivot, so that brake bar 118 is discharged from the set ring sleeve 116 of piston 40.(it has passed through electromagnetism or hydraulic dress to piston 40 Set and discharged from stop device 46) now can according to the actuating state of parking lock 12 and by the spring force of piston spring 44 from Its unlocked position is moved to its latched position or is moved to its unlock from its latched position by the hydraulic loaded of pressure chamber 48 Position.

In addition, especially as shown in figure 9, piston 40 is formed as the hollow part of rotational symmetry, in Fig. 9 from right to left With funnel-shaped opening region 156, for piston rod 42 piston side end receiving area 158 and for thrust piece 62 The hollow cylindrical receiving area 160 of piston side end.Piston rod 42 prolongs to the right in Fig. 9 from the open area of piston 40 156 It stretches, wherein the support lantern ring 162 for piston rod spring 50 being formed on piston rod 42 is axially located at the opening of piston 40 In region 156.According to the outer diameter of support lantern ring 162, piston rod 42 can be pivoted in open area 156 relative to piston 40.

In its piston side end, metallic piston bar 42 has bulb 164, and bulb 164 is maintained at the central acceptance of piston 40 In region 158.Here, bulb 164 is supported on bearing seat 166, and bearing seat 166 has the complementary shape relative to ballhead 164 It shape and is formed on piston 40, so that piston rod 42 is hingedly mounted on piston 40.Thrust piece 62 is towards piston rod 42 Side there is carrying protrusion 168, which extends in the receiving area 158 of piston 40 and has for piston rod 42 The spherical cap abutment surface 170 of bulb 164.The bearing seat 166 and thrust piece 62 of the bulb 164 of piston rod 42 in piston 40 It is kept substantially very close to each otherly between spherical cap abutment surface 170.

Finally, receiving the head 172 of thrust piece 62, the head in the left hand receiving area 160 of the piston 40 in Fig. 9 It is similarly formed as plastic injection piece.Carrying protrusion 168 is formed on the head 172 of thrust piece 62.In addition, thrust piece 62 Head 172 equipped with lantern ring 174, form the support of the piston side end of piston spring 44, around head 172 and extend Into the receiving area of piston 40 160.Helically the piston spring 44 of spring form abuts against piston 40 with its lantern ring 174 Annular shoulder 176 preload thrust piece 62, the annular shoulder be located at receiving area 158 and piston 40 receiving area 160 it Between.

In addition, especially can as seen from Figure 9, thrust piece 62 has in the side far from actuating component 34 or piston rod 42 Guide extension 178.It such as will be discussed in further detail below, the pin-shaped guidance integrally abutted with the head 172 of thrust piece 62 Extension 178 is guided by means of guide bushing 180 relative to shell 30, on guide bushing 180 itself tight to shell 30. In the illustrated exemplary embodiment, the guide bushing 180 for being similarly formed as plastic injection piece is fastened to shell by bayonet connection Body 30, bayonet connection are indicated in Fig. 2 to 5 and 9 with reference label 182.Use for the clutch master cylinder as hydraulic cylinder The bayonet connection 182 of situation, the type is retouched in detail in the German patent application DE102016006053A1 of same applicant It states, about the structure and function of the connection, at this crucial hour explicitly with reference to the document.

As shown in figure 9, piston spring 44 is supported on guide bushing 180 with its end far from piston 40.More specifically, Guide bushing 180 on the side of its inner space 88 towards shell 30 equipped with annular incision 184, piston spring 44 it is remote The end from piston 40 extends in annular incision 184.Therefore, guide bushing 180 also serves as the shell for piston spring 44 Side latch plate.

It will therefore be apparent that any impact of the piston rod 42 on unlocking direction E, such as can be in actuating element 26 Quickly return and piston rod spring 50 are introduced into piston rod 42 in the case where settling via support lantern ring 162, cannot be transmitted to Piston 40, but be transmitted to guide bushing 180 via thrust piece 62 in a manner of being damped by piston spring 44 and be therefore transmitted to Shell 30.In other words, between piston 40 and piston rod 42, although the bulb 164 due to piston rod 42 abuts against piston 40 Bearing seat 166 and have anti-traction shape be cooperatively connected, but without anti-thrust connection, because if being applied to piston rod 42 Thrust be more than piston spring 44 preloaded force, then by the bulb 164 of piston rod 42 via the thrust that pushes of carrying protrusion 168 Part 62 can be lifted from piston 40 at the annular shoulder 176 of piston 40.

Guide bushing 180 also executes ventilation function.If Fig. 2 and Fig. 5 are specifically shown, guide bushing 180 is from far from piston 40 End start, equipped with for shell 30 inner space 88 carry out degasification opening 186.The exemplary implementation shown in In example, the opening 186 for being parallel to central axis M extension is located on common pitch circle, and surrounds central axis M each other equably It is angularly spaced (referring to Fig. 5).

The further details of sensor device 54 particularly occur on Fig. 2,4,5 and 9 to 12.Sensor device 54 is preferably It is Hall sensor systems, with Hall element (not shown in detail) as the position detector 56 (figure fixed relative to shell 9) component part, and there is the magnet as position coder 58, piston 40 is connected to by retainer 60.It compiles position Code device 58 can for example be adhered to retainer 60, but injection molding is plastic bonding magnet preferably in retainer 60, at this In the case of kind, it is similarly formed as plastic injection piece.

Retainer 60 for position coder 58 usually has angled arm 188, and position coder 58 is maintained at shell On the excircle of body 30.In addition, the movement for piston 40 couples, retainer 60 has coupling part 190, relative to center Axis M is disposed concentrically upon and is connected to angled arm 188, more specifically, in the illustrated exemplary embodiment, by keeping The plastic material and arm 188 of device 60 are integrally molded molding.

Movement connection for piston 40, the coupling part 190 of retainer 60 as shown in Figure 9 extends to the interior of shell 30 In portion space 88.Here, the sleeve-shaped coupling part 190 of retainer 60 is by means of the guide bushing 180 that is fastened on shell 30 It is guided and is maintained on the guidance extension 178 of thrust piece 62, axially there is no playback (playback), without It is rotationally coupled to thrust piece 62.In other words, the guidance extension 178 of thrust piece 62 extends to the coupling part of retainer 60 In 190 and by the latter, so that the guidance extension 178 of thrust piece 62 passes through more specifically its coupling part of retainer 60 190 are guided in guide bushing 180 indirectly, for this purpose, it has hollow cylindrical guiding surface 192 in central area.

It can also be seen that the movement for the retainer 60 for position coder 58 to piston 40 couples in Fig. 9, mention Snap-action has been supplied to connect 194.By snap-action connection 194, the retainer 60 for position coder 58 is maintained at drawing for thrust piece 62 It leads on extension 178, wherein snap-action connection 194 is arranged on the end of coupling part 190 of retainer 60, and the end is close to living Plug.In this case, the coupling part 190 of retainer 60 is formed with multiple slits, to form spring arm 196, spring arm 196 have lug-shaped protrusion 198 in its free end on inner periphery.Lug-shaped protrusion 198 is under the assembled state of retainer 60 It is bonded on behind the circumferential collar 200 on the guidance extension 178 of thrust piece 62.Since the coupling part 190 of retainer 60 is gone back The head 172 of thrust piece 62 can be abutted against in surface side, the coupling part 190 of retainer 60 is axial solid in form-fit fashion Surely thrust piece 62 is arrived, but still allows thrust piece 62 relative to 60 relative rotation of retainer.

About drawing for the retainer 60 for being used for position coder 58 on the outside for the shell 30 in parking lock module 10 The guide sections led and (acted with rail-like) point 64, also with particular reference to Fig. 2 and 12.According to the figure, in the outer circle of shell 30 Leader 64 on week has rib 202,204, and rib 202,204 is integrally molded and along lock by the plastic material of shell 30 Direction S and unlocking direction E are determined with rail-like motion guiding retainer 60, and the fixed retainer is to prevent relative to shell 30 rotations.Rib 202,204 longitudinally extends relative to central axis M and the rib 206 by being laterally extended relative to central axis M Reinforce.

Here, leader 64 has the first guiding surface 208 on external fin 202, during the first guiding surface 208 is parallel to Mandrel line M extension and facing each other and the arm 188 with the retainer 60 for position coder 58 (referring also to Figure 10) First be laterally abutted surface 210 interaction, with Support Position encoder 58 prevent around central axis M rotate.In addition, drawing Part 64 is led at least one (being in the illustrated exemplary embodiment two) another guiding surface 212, is formed in interior On rib 204, internal-rib 204 is between central axis M and position coder 58, and as shown in figure 11, and for position encoded At least one another abutment surface 214 on the arm 188 of the retainer 60 of device 58 interacts, to exist relative to central axis M Support Position encoder 58 in the radial direction.Since retainer 60 is formed by plastics and due to plastics after injection molding process Shrinkage behavior, the arm 188 of retainer 60 abut against the guidance of shell 30 with lesser spring force together with another abutment surface 214 Another guiding surface 212 of part 64.

It can be clearly seen that retainer 60 passes through its angled arm relative to central axis M in from the description above 188 or coupling part 190 along the circumferential direction between rib 202 and radially on rib 204 and in guide bushing 180 Guiding surface 192 and thrust piece 62 guidance extension 178 between be guided, there is no gap or have it is very small Gap.In addition, retainer 60 and the axially coupled of thrust piece 62 also show very small gap at snap-action connection 194.This The height acquisition precision and reliability of sensor device 54 are all advantageous.However, retainer 60 and therefore position are compiled Code device 58 can be moved with low-down displacement force along central axis M relative to position detector 56 because retainer 60 with Thrust piece 62 rotatably separates, prevent those of generating torque for example during the compression of piston spring 44 from from thrust piece 62 It is transmitted to retainer 60, therefore retainer 60 will not be stuck in its guiding piece on shell 30.

Finally, by means of sensor device 54, the corresponding actuating state of parking lock module 10 available first, also It is to say whether the piston 40 of actuating mechanism 32 is located at latched position as shown in Figure 9 or is in the unlocked position.Secondly, can detecte Possibility to the damage of parking lock module 10, such as piston spring 44 is destroyed.In addition, however connecing for parking lock 12 can also be controlled It closes and separates, pressurize especially by the stroke for obtaining piston 40 and in a manner of dependent on this to pressure chamber 48.It equally can be with " ratcheting " of the pawl 18 on the tooth 16 of parking lockwheel 14 is detected, therefore this can be offset by pressurizeing to pressure chamber 48 Kind situation.

A kind of parking lock module has shell, accommodates actuating mechanism in the housing, which is hingedly attached to Actuating component.In the end far from actuating mechanism, which has the actuating element with conical surface portion, the taper Surface portion can be contacted with tapered guide element, which fixes relative to shell and in metal profile Form.During the movement of the actuating component generated by actuating mechanism, conical surface portion is supported on support along the longitudinal direction On the support section of plate, and herein, by the deflection of actuating component, the movement of actuating element in a lateral direction is realized, To activate parking lock.Especially for mitigation weight and in order to simplify assembling process, shell is molded of plastic material and props up Fagging is integrated in the housing, so that the support section of support plate with actuating element in order to contact and protrude past the plastics material of shell Material.
