Description

Technical Field

[0001] The utility model relates to a device comprising a rod-shaped component and another component supported on the rod-shaped component in a longitudinally movable manner, and a parking lock facility comprising the device. Background Art

[0002] A parking lock system for a motor vehicle is known from DE 10 2019 001 189 A1 and comprises a housing and a drive shaft that can be coupled to a wheel of the motor vehicle. Furthermore, a locking element is provided, by which the drive shaft can be connected to the housing in a rotationally fixed manner. Furthermore, the parking lock system comprises an actuating element that is configured to actuate the locking element.

[0003] The operating element is arranged longitudinally movable on a rod-shaped component or an operating lever, wherein the adjustment travel of the operating element is limited by two adjustment travel stop regions. A spring is supported on one of the adjustment travel stop regions and on the operating element, and acts upon the operating element with its spring force in the direction of the other adjustment travel stop region. The other adjustment travel stop region is implemented as an area of ​​increased diameter of the rod-shaped component at the end of the rod-shaped component.

[0004] During actuation of the parking lock, the actuating element is adjusted counter to the spring force of the spring and, when the parking lock is engaged, strikes the further adjustment travel stop region of the rod-shaped component at a high adjustment speed. The further adjustment travel stop region of the rod-shaped component is thereby undesirably loaded with high impact pulses, which impairs the service life of the parking lock. Utility Model Content

[0005] The object of the present invention is to provide a device with a simple structure and a long service life, which device comprises a rod-shaped component and a further component mounted longitudinally displaceably on the rod-shaped component, and to provide a parking lock arrangement having such a device.

[0006] According to the invention, this object is achieved with the device and parking lock arrangement described herein.

[0007] The device according to the present invention comprises a rod-shaped component and a further component supported on the rod-shaped component in a longitudinally movable manner. A spring unit acts on the further component in a first adjustment direction. The further component can be adjusted in a second adjustment direction in opposition to the spring force of the spring unit.

[0008] The rod-shaped component is fastened to the carrying unit in a manner that is essentially immovable in the longitudinal direction, and the adjustment travel of the further component is limited by means of a stop device of the carrying unit.

[0009] The rod-shaped component can be fastened to the carrier unit so that a small gap exists between the rod-shaped component and the carrier unit in the longitudinal direction, and the rod-shaped component can be moved in the longitudinal direction within the gap. In addition, the rod-shaped component is held peripherally so that further components can be guided on the rod-shaped component in a defined manner.

[0010] Because the adjustment travel of the additional components in the device according to the present invention is no longer limited by a rod-shaped component, as in known solutions, but rather by a separate support unit, the device according to the present invention can be implemented more robustly with a simple construction compared to known solutions, ensuring that the device's functionality remains continuously available. All mechanically loaded areas and cross-sections of the device can be designed to suit the load in a cost-effective and space-saving manner. This allows the device according to the present invention to have a desired long service life, which, particularly when used in a vehicle, essentially corresponds to the service life of the vehicle. Consequently, vehicle maintenance costs can be limited, and vehicle availability can be consistently ensured.

[0011] The stop device of the carrying unit can be designed to have at least two adjustment travel stop regions, which limit the adjustment travel of the further component along the rod-shaped component, i.e., in the longitudinal direction of the rod-shaped component. As a result, the adjustment travel of the further component can be limited completely independently of the mechanical loadability of the rod-shaped component, since the rod-shaped component is merely provided for guiding the further component.

[0012] In a space-saving embodiment of the device according to the invention, the spring unit surrounds the rod-shaped component and is arranged between the further component and the spring stop region of the carrier unit.

[0013] Furthermore, the rod-shaped component can be arranged in the longitudinal direction between the first rod stop region and the second rod stop region of the carrier unit. Thus, the rod-shaped component is held in the longitudinal direction by the carrier unit within a defined range in a structurally simple manner.

[0014] The rod-shaped component can penetrate the adjustment path stop region or at least one of the adjustment path stop regions in the longitudinal direction. This allows the rod-shaped component to be operatively connected to one of the two rod stop regions on the side of the adjustment path stop region facing away from the other component, and additionally be operatively connected at least partially around the periphery to the support unit. In this embodiment of the device according to the invention, the rod-shaped component can be supported in the region of the support unit completely independently of the support of other components in the region of the support unit and can be maintained in a defined position.

[0015] At least one of the adjustment travel stop regions of the load-bearing unit can be arranged in the region of a stop element. This makes it possible to initially direct the impact of the other component, which is to be supported in the region of the adjustment travel stop region, into the stop element. Such a stop element can be made, at least in the region impacted by the other component, from a material that withstands the loads occurring therein and, for example, can be embodied with a corresponding impact or stop surface for the other component in order to achieve the lowest possible surface pressure.

[0016] The rod-shaped component can be embedded at least partially in the recess of the stop element at the end. In addition, there is the possibility that the rod stop area and the adjustment stroke stop area of ​​the other component can be formed in one piece. Thus, the device according to the utility model can be implemented with a small number of components.

[0017] However, it can also be provided that the rod-shaped component passes through the stop element at the end in the region of the recess and interacts with the rod stop region on the side of the stop element facing away from the further component.

[0018] The carrier unit can have two carrier sections extending in the longitudinal direction of the rod-shaped component, which can be implemented, for example, as bent stamped parts. It can be provided that the carrier sections are connected to one another so that they form a frame for the component and further components. The carrier sections can abut against one another in the region of the carrier end sections and, in the region between the carrier end sections, include carrier core sections that are spaced apart from one another in the transverse direction of the rod-shaped component. A carrier intermediate section can be provided between each of the carrier end sections and the carrier core section, connecting the carrier end sections to the carrier core section.

[0019] In further embodiments, the carrier end sections may also be spaced apart from one another in the transverse direction of the rod-shaped component.

[0020] The support unit thus easily has a receiving space between the support segments, in which rod-shaped components and other components can be arranged and held. Furthermore, the support segments can be designed in a desired manner to have the required mechanical strength in order to absorb the loads occurring during operation of the device.

[0021] Depending on the respective application, the carrier middle section can extend in the transverse direction of the rod-shaped component, in the longitudinal direction of the rod-shaped component and / or in the transverse direction and longitudinal direction of the rod-shaped component between the carrier end section and the carrier center section and thus be adapted to the available structural space in a simple manner.

[0022] In one embodiment of the device according to the invention that can be manufactured with little effort, the spring stop region comprises an at least approximately U-shaped stop element. The stop element can be fixedly connected to the carrier center section in the region of the lateral legs and has a through-opening for the rod-shaped component in the region of the base portion connecting the legs. The rod-shaped component can then be passed through the base portion of the spring stop region and guided circumferentially on the carrier unit, while the spring unit can be supported longitudinally on the base portion and transversely on the lateral legs.

[0023] At least one of the rod stop regions can be formed by two carrier middle sections in the carrier middle section. In other words, the rod-shaped component can be abutted against the carrier middle sections extending toward each other at the end side and remain thereon in the longitudinal direction.

[0024] In a mechanically robust embodiment of the device according to the invention, which also has a low component weight, one of the adjustment travel stop regions can include an at least approximately rectangular hollow body. The hollow body can rest with its parallel lateral regions against the carrier center section and be fixedly connected there. A stop surface of the adjustment travel stop region can be provided in the middle region of the hollow body, perpendicular to the mutually parallel lateral regions of the hollow body. In the region of the stop surface, kinetic energy of the other component can be introduced into the support unit when the adjustment travel of the other component is limited.

[0025] The hollow body can be designed with a through-opening at least in the central region forming the stop surface, in the region of which the rod-shaped component passes through the central region of the hollow body and is guided or held on the circumference on the carrying unit.

[0026] There is also the possibility of designing the further component at least approximately cylindrically and having the rod-shaped component pass through it in the region of the central opening. The further component can each be designed with a flat contact surface in the region of its end faces in order to generate as low a surface pressure as possible when it strikes a stop surface in the region of the adjustment travel stop.

[0027] If the additional component has a conical surface section between the flat contact surface facing away from the spring unit and the at least approximately cylindrical lateral surface, the additional component can be guided along the additional component by means of the low spring force of the spring unit in order to be able to actuate this additional component as required. This component can be, for example, a pawl of a parking lock or the like.

[0028] If the carrying unit is a one-piece bent and punched part, the device according to the invention can be produced cost-effectively with little assembly effort.

[0029] The support unit can have a through-opening for a rotary joint in the region of a support end section connected to the support middle section and arranged on the side of the spring unit facing away from the further components, about whose rotation axis the support unit and thus the entire device can be pivoted.

[0030] Furthermore, the present invention relates to a parking lock arrangement, in particular a parking lock arrangement of an electrically drivable axle, which is embodied with the device described in detail above.

[0031] The further component can be designed as an actuating element which can be brought into or out of engagement with a locking element, for example a pawl, via which a rotational movement of the shaft can be blocked and released.

[0032] A parking lock is to be understood as meaning, in particular, a system which is designed to lock the drive train of a motor vehicle in the engaged state, in particular in the area of ​​the transmission, so that at least one output shaft of the transmission is blocked and the motor vehicle is secured against rolling away when stationary. The engaged state of the parking lock corresponds in particular to the so-called park-engaged state. In the disengaged state, the parking lock is designed to release the output shaft.

[0033] The disengaged state of the parking lock device corresponds in particular to the so-called park-disengaged state (P_aus-Zustand). For this purpose, the parking lock device preferably has a parking lock wheel. In this context, the parking lock wheel is to be understood as a gear having a toothing on its circumference, which is configured to couple with a locking element, in particular a pawl, that is at least partially fixed relative to the housing. Preferably, the locking element is configured to fix the parking lock wheel relative to the housing in the engaged state of the parking lock device. In this context, the pawl is to be understood as an element that can be pivoted between two operating positions, which is configured with at least one ratchet tooth that is configured to correspond to the toothing of the parking lock wheel and is configured to engage with a positive fit in the toothing of the parking lock wheel when the parking lock device is engaged.

[0052] Figure 1 The figure shows a simplified view of an electrically drivable axle 1 with a drive unit 2. The drive unit 2 comprises an electric motor 3, an inverter 4 for the electric motor 3, and a transmission unit 5. An output shaft 6 of the electric motor 3 is arranged coaxially with a transmission input shaft 7 of the transmission unit 5 and is connected thereto in a rotationally fixed manner.

[0053] The transmission input shaft 7 is operatively connected to the transmission output shaft 10 via gear pairs 8 and 9 of the transmission device 5. In this embodiment, the gear pairs 8 and 9 are embodied as spur gear meshes and each include a first spur gear 8A or 9A and a second spur gear 8B or 9B. The first spur gear 8A of the first gear pair 8 is arranged in a rotationally fixed manner on the transmission input shaft 7 and meshes with the second spur gear 8B of the first gear pair 8. The second spur gear 8B of the first gear pair 8 is arranged in a rotationally fixed manner on the intermediate shaft 51, on which the first spur gear 9A of the second gear pair 9 is mounted in a rotationally fixed manner. The first spur gear 9A of the second gear pair 9 meshes with the second spur gear 9B, which is arranged in a rotationally fixed manner on the transmission output shaft 10.

[0054] The electric machine 3, the inverter 4 and the transmission device 5 are arranged in a transmission housing 11 or in the housing of the drive device 2. An intermediate wall 12 divides the interior of the transmission housing 11 into an oil-free interior 13 and an oil-filled interior 14.

[0055] In the switched-off operating state of the drive unit 2, there is no torque on the transmission input shaft 7 on the side of the electric machine 3, so that the transmission output shaft 10 is freely rotatable. In order to prevent undesired rolling when the vehicle is parked, especially in a tilted position, the transmission device 5 also includes a parking lock 15.

[0056] The transmission output shaft 10 can be rendered rotationally fixed by a parking lock device 15. For this purpose, the parking lock device 15 comprises a drive device 16 having an electric motor 16A. The drive device 16 or its electric motor 16A can be actuated in Figure 2The parking lock mechanism 17 is shown in a side view. The parking lock mechanism 17 also includes a locking element 18, which is designed as a so-called pawl. The locking element 18 can be engaged or disengaged with a parking lock wheel 19 when the electric motor is actuated. Figure 1 In the exemplary embodiment shown, the parking lock wheel 19 is arranged on the transmission input shaft 7 in a rotationally fixed manner.

[0057] To prevent functional problems with the drive device 16 and the electric motor 16A due to oil entering the housing 20 of the electric motor 16A, the electric motor 16A is fixedly mounted on the intermediate wall 12 on the side of the intermediate wall 12 that faces the oil-free interior 13. To actuate the parking lock mechanism 17, the electric motor 16A extends through the intermediate wall 12 with its drive shaft 21. To prevent oil from undesirably entering the oil-free interior 13 from the oil-filled interior 14 through the intermediate wall 12, a sealing unit (not shown in detail) is provided between the drive shaft 21 of the electric motor 16A and the intermediate wall 12.

[0058] In addition to the motor 16A, an electrical plug unit 22 is arranged in the oil-free interior 13 , by which the motor 16A can be controlled and operated in a desired manner. Additionally, a solenoid 23 is also fixedly fastened to the intermediate wall 12 in the oil-free interior 13 .

[0059] The parking lock mechanism 17 is configured with a first drive element 24 which is Figure 2 In a manner and method described in detail in FIG, a second drive element 27 engages with a gear wheel 26 via a toothing 25. Gear wheel 26 is connected to the drive shaft 21 of the electric motor 16A in a rotationally fixed manner. A second drive element 27 is operatively connected to the first drive element 24 via a spring unit 28, which is supported on the first drive element 24 and the second drive element 27 and, in the installed state, is preloaded between the two drive elements. The first drive element 24 can be pivoted about an orientationally fixed rotation axis 29 via the drive device 16. The second drive element 27 can be connected to the first drive element 24 in a rotationally fixed manner via a latching device 30 and can then be pivoted together with the first drive element 24 about the rotation axis 29.

[0060] Furthermore, the parking lock arrangement 15 comprises an actuating element 31 which can be engaged or disengaged with the locking element 18 depending on the pivoting movement of the second drive element 27. Figure 2 The locking element 18 can block the rotational movement of the transmission input shaft 7 when the locking element 18 is engaged in the parking lock wheel 19 in a form-locking manner as shown in detail in FIG. Figure 3When the engagement with the parking lock wheel 19 is disengaged in the manner and method shown, the rotational movement of the transmission input shaft 7 is released via the locking element 18 .

[0061] The second drive element 27 is connected to the operating element 31 via a rod-shaped component or an operating rod 32. A spring unit 33 and the operating element 31, which is spring-loaded by the spring unit and arranged longitudinally displaceably on the operating rod 32, are provided on the operating rod 32.

[0062] Figure 2 The parking lock arrangement 15 is shown in the engaged state and in the so-called normal operating state, in which the first drive element 24 is connected to the second drive element 27 in a rotationally fixed manner via a blocking device 30. The blocking device 30 can be actuated by the solenoid 23 in a manner described in detail below.

[0063] Additionally, Figure 3 The parking lock arrangement 15 is shown in the disengaged operating state, in which the positive connection between the locking element 18 and the parking lock wheel 19 is released by actuating the respective electric motors of the first drive element 24 and the second drive element 27, which is non-rotatably connected thereto. In this state, the locking element 18 is held disengaged from the parking lock wheel 19 by a further spring unit 34 operatively connected to the locking element 18. The spring unit 34 is designed as a torsion spring and is supported on the locking element 18 and the second drive element 27. The actuating element 31 is arranged between a guide element 35 fixed to the housing and fixedly connected to the intermediate wall 12, and a side 36 of the locking element 18 facing away from the parking lock wheel 19. The actuating element 31 rests with its conical region 37 on a tapered bevel 35A of the guide element 35 and on a tapered bevel 38 of the pawl or locking element 18.

[0064] To engage the parking lock 15, the motor 16A rotates the drive shaft 21 and the gear 26 connected thereto in a rotationally fixed manner. This causes the first drive element 24 to pivot about the axis of rotation 29 in the direction of rotation DR1. Figure 4The manner and method shown in detail in FIG1 is fixedly connected to the first drive element 24 not only in the region of the pin-shaped projection 39 of the first drive element 24 but also in the region of the locking element 40 of the locking device 30. Therefore, the second drive element 27 of the electric motor 16A is pivoted together with the first drive element 24 about the rotation axis 29 in the rotation direction DR1. This causes the actuating lever 32 to be displaced in the direction of the actuating element 31. The spring unit 33 is compressed until the actuating element 31 moves counter to the spring force of the spring unit 33 along the inclined portion 38 of the locking element 18 and along the inclined portion 35A of the guide element 35 and abuts against the stop region 67. The locking element 18 is then guided counter to the spring force of the spring unit 34 into engagement with the parking lock wheel 19. This occurs when the two drive elements 24 and 27 of the electric motor 16A are adjusted in the swivel direction DR1 until the actuating force exerted by the spring legs 34A of the spring unit 34 on the locking element 18 drops to a level at which the locking element 18 can be pivoted about the rotation axis 41 and engage with the parking lock wheel 19.

[0065] The locking element 40 passes through the intermediate wall 12 and the first drive element 24, is arranged coaxially with the rotation axis 29 and is designed to be longitudinally displaceable in the direction of the rotation axis 29. Figure 4 In the operating state shown, the solenoid 23 is not energized and the locking element 40 is held in engagement with the second drive element 27 by a spring not shown in detail in the drawings. Figure 4 It can be seen that the first drive element 24 is rotatably supported in the intermediate wall 12 via a bearing unit 48 designed as a rolling bearing. Depending on the respective application, there is the possibility of also designing the bearing unit 48 as a sliding bearing.

[0066] A bolt-shaped projection 39 extends through the second drive element 27 in the region of the two legs 27C, 27D, which are spaced apart from one another in the direction of the further axis of rotation 45. In this case, the spring unit 28 is also arranged between the legs 27C and 27D on the bolt-shaped projection 39, so that tilting moments acting on the second drive element 27 can be supported in the region of the legs in a simple manner.

[0067] In the engaged state of the parking lock arrangement 15, the first drive element 24 is spaced apart from the housing-side stop 42, and the second drive element 27 abuts against the housing-side stop 43. In the disengaged operating state of the parking lock arrangement 15, the first drive element 24 is positioned in the region of the further housing-side stop 44.

[0068] If the parking lock arrangement 15 is transferred to the disengaged operating state, the first drive element 24 is correspondingly displaced about the rotation axis 29 in the swivel direction or rotation direction DR2 by the electric motor 16A, which also leads to a pivoting of the second drive element 27 about the rotation axis 29. The pivoting of the second drive element 27 about the rotation axis 29 causes the guide actuating element 31 of the actuating lever 32 to be disengaged from the inclined portion 38 of the locking element 18 and the inclined portion 35A of the guide element, and the locking element 18 is disengaged from the parking lock wheel 19 by the acting spring unit 34.

[0069] If a fault in the area of ​​the drive 16 is detected in the disengaged operating state of the parking lock arrangement 15 (which does not allow the parking lock arrangement 15 to be engaged by the electric motor 16A and there is a corresponding request to engage the parking lock arrangement 15), the solenoid 23 is electrically activated accordingly. The solenoid 23 then guides the locking element 40 out of engagement with the second actuating element 27 counter to the acting spring force. Figure 5 This operating state of the blocking element 40 is shown in detail in FIG.

[0070] Since the active connection between the gear wheel 26 and the toothing 25 of the first drive element 24 is in the present case designed as self-locking, the first drive element 24 remains in the Figure 3 The pivoted position shown corresponds to the engaged operating state of the parking lock arrangement 15. By pulling the locking element 40 out of engagement with the second drive element 27, the rotationally fixed connection between the first drive element 24 and the second drive element 27 is released in the region of the axis of rotation 29. This results in the second drive element 27 being released by the spring unit 28, which is arranged in a prestressed state between the two drive elements 24 and 27. Figure 4 The pivot position shown is pivoted about the pin-shaped projection 39 in the direction of rotation DR1 until the second drive element 27 is in the direction of rotation DR2. Figure 6 The manner shown abuts against a stop 43 on the housing side.

[0071] By this pivoting movement of the second drive element 27 about the rotation axis 45 present in the region of the bolt-shaped projection 39, the actuating element 31 is moved in the manner described in detail above between the guide bevel 35A of the guide element 35 and the guide bevel 38 of the locking element 18. Thus, a positive fit is established between the locking element 18 and the parking lock wheel 19.

[0072] In order to be able to return the thus emergency-unlocked parking lock arrangement 15 to the disengaged operating state as needed, an actuating force F can be applied to the second drive element 27 via a corresponding device to impart a rotational movement in the rotational direction DR2 to the second drive element 27. This rotational movement causes the second drive element 27 to abut against a further stop 46 starting from a specific rotational angle, which limits the rotational movement of the second actuating element 27 about the rotational axis 45. The further stop 46 is positioned so that a hole 47 in the second drive element 27, which is provided for accommodating the locking element 40, coincides with the locking element 40, and the locking element 40 is spring-actuated into the hole 47. The parking lock arrangement 15 is thus disengaged again, and the transmission input shaft 7 is rotatable.

[0073] In this case, the adjusting force F can be exerted mechanically as a compressive or tensile force on the second drive element 27 in order to transfer the parking lock arrangement 15 into the disengaged operating state.

[0074] The operating element 31 and the operating lever 32 are each part of the device 60. Figure 7 The device 60 comprises a support unit 61 on which the actuating lever 32 is fastened substantially immovably in the longitudinal direction x and on which the adjustment travel of the actuating element 31 is limited by a stop 62 .

[0075] The stop device 62 of the support unit 60 comprises two adjustment travel stop areas 63 and 64, by which the adjustment travel of the actuating element 31 along the actuating rod 32 is limited. The spring unit 33 surrounds the actuating rod 32 and is arranged between another component or the actuating element 31 and a spring stop area 65 of the support unit 61.

[0076] The actuating rod 32 passes through the adjustment travel stop region 63 and also in the longitudinal direction x through a further adjustment travel stop region 64 of the stop device 62 and is arranged in the longitudinal direction x between a first rod stop region 66 and a second rod stop region 67 of the carrying unit 61 .

[0077] Here, the actuating lever 32 is operatively connected to a second lever stop region 67 on the side of the adjustment travel stop region 64 facing away from the actuating element 31. In addition, the actuating lever 32 rests with its other end on a first lever stop region 66, which is arranged or provided on the side of the spring stop region 65 facing away from the spring unit 33.

[0078] The support unit 61 has two support sections 68, 69 extending in the longitudinal direction x of the rod-shaped component or actuating lever 32, which are connected to each other via base areas 78, 79. The support sections 68, 69 each include support end sections 68A, 68B or 69A, 69B. Additionally, the support sections 68, 69 form a support center section 68C or 69C between the support end sections 68A, 68B or 69A, 69B, respectively. A support center section 68D, 68E or 69D, 69E, respectively, is arranged between the support end sections 68A, 68B or 69A or 69B and the support center section 68C or 69C.

[0079] In the carrier unit 61 or the device 60 Figure 7 In the embodiment shown, the two carrier end sections 68A and 69A are arranged spaced apart from one another in the transverse direction y and are each formed with a through-opening 68F or 69F, in the region of which the device 60 is mounted on the second drive element 27 so as to be rotatable about a rotation axis 70 of a rotation joint 71. The device 60 can thus be pivoted about the rotation axis 70.

[0080] The rod stop region 66 is formed by two intermediate carrier sections 68D, 69D. The intermediate carrier sections 68D, 69D extend both in the transverse direction y and in the longitudinal direction x of the actuating rod 32 between the carrier end sections 68A and 69A and the carrier center sections 68C, 69C. In contrast, the intermediate carrier sections 68E, 69E extend in the longitudinal direction x.

[0081] Figure 8 A further three-dimensional single view of the device 60 is shown in a front view obliquely from above. Figure 8 The illustration shows that the actuating element 31 rests with its flat end face 72 on the adjustment travel stop region 64. The adjustment travel stop region 64 is formed by a curved lateral tongue 73, 74 of the carrier middle section 68E, 69E, respectively.

[0082] Figure 9 Along Figure 7 The longitudinal section along the cutting line IX-IX shown in detail in FIG. Figure 7 Device 60. From according to Figure 9 The illustration shows that the actuating element 31 is designed with a central hole 75, in the region of which the actuating rod 32 passes. The rod stop region 67 of the device 60 is formed by two further curved lateral tongues 76, 77, which are designed integrally with the carrier end sections 68B, 69B. The carrier center section 69C is designed with a mounting stop 105 for the pawl 18.

[0083] Figure 10 The expanded view of the carrier unit 61 is shown, which is initially designed as a flat sheet metal stamping and is subsequently deformed in a suitable manner with the aid of a bending tool and suitable holders into a flat sheet metal stamping. Figure 7 and Figure 8 The shape is shown in detail.

[0084] Additionally, Figure 11 The device 60 is shown in a front view, in which two further curved lateral tongues 76 and 77 and the ends of the actuating lever 32 cooperating therewith are shown in detail.

[0085] During the production of the carrier unit 61, the carrier middle sections 68D, 69D are first bent into the shown bent shape by bending relative to the carrier center sections 68C and 69C and the carrier end sections 68A, 69A. Subsequently, the carrier center sections 68C, 69C together with the carrier end sections 68A, 68B, 69A, 69B are bent upwards essentially by 90° relative to the base areas 78, 79 of the carrier unit 61. In addition, the two center tongues 82, 83, which are designed with openings 80, 81, are also bent upwards by 90° relative to the base areas 78, 79. Subsequently, the two lateral tongues 73, 74 are converted from a flat shape into a flat shape. Figure 9 and Figure 11 , so that a stop surface can be provided for the actuating element 31. Subsequently, the spring unit 33 and the actuating element 31 are placed between the carrier sections 68, 69 or their carrier center sections 68C, 69C, and the actuating rod 32 is guided through the two openings 80, 81 and the spring unit 33 and the actuating element 31 until the end of the actuating rod 32 abuts against the rod stop area 66. Subsequently, two further lateral tongues 76, 77 are transferred to Figure 8 The shape shown is used to fix the operating rod 32 in the longitudinal direction x.

[0086] Figure 12 A further device 160 is shown, which is in accordance with Figure 7 The device 60 differs only in some areas. Therefore, in the following description of the device 160, for the sake of clarity, the same reference numerals are used for structurally and functionally identical components, and essentially only the differences between the device 60 and the device 160 are discussed in detail. With regard to the further functionality of the device 160, reference is made to the above description of the device 160. Figures 7 to 11 Description.

[0087] Device 160 further includes a support unit 61 having support end sections 68A, 68B and 69A, 69B. Here, the support center sections 68C and 69C extend substantially in the longitudinal direction x of the actuating rod 32. Between the support end sections 68A, 69A and the support center sections 68C, 69C, support intermediate sections 68D and 69D extend substantially in the transverse direction y of the actuating rod 32 and in the axial direction, or longitudinal direction x, from the support center sections 68C, 69C in an arrow-shaped manner toward the support end sections 68A, 69A. In contrast, the support intermediate sections 68E, 69E extend substantially only in the transverse direction y of the actuating rod 32 from the support center sections 68C, 69C toward each other and are connected to the support end sections 68B, 69B extending in the longitudinal direction x. The carrier sections 68 and 69 are each integrally connected to one another in the region of the carrier end sections 68A, 69A and 68B, 69B in the region of the weld seams 84 , 85 .

[0088] Additionally, Figure 13 The device 160 is shown in a top view. Figure 14 China and Israel Figure 13 A longitudinal sectional view along line XIV-XIV is shown in detail.

[0089] Device 160 includes a stop and guide element 86, which is essentially U-shaped and rests with its lateral legs 87, 88 against the inner sides of the carrier center sections 68C, 69C, respectively, and is fixedly connected to the two carrier center sections 68C, 69C in the contact area. A spring stop area 65 and a through-opening 90 are provided in the area of ​​the base section 89, through which the actuating rod 32 is guided. The actuating rod 32 rests with one end on the side of the base section 89 facing away from the spring unit 33 against the two carrier center sections 68D, 69D, which form the rod stop area 66.

[0090] On the other hand, the actuating rod 32 passes through a stop element 91, which is designed as a substantially rectangular hollow body. Its first two parallel lateral areas 92, 93 rest against the inner sides of the carrier core sections 68C, 69C and are fixedly connected there to the carrier core sections 68C, 69C. The middle areas 94, 95 extending between the two parallel lateral areas 92, 93 are each formed with through-openings 96, 97, in the region of which the actuating rod 32 passes through the stop element 91 and is retained by the stop element 91. The middle area 94 forms the adjustment travel stop area 64.

[0091] The two carrier end sections 68B, 69B essentially again present a rod stop region 67 for the actuating rod 32, wherein the actuating rod 32 has a certain axial play between the rod stop regions 66 and 67. This means that the length of the actuating rod 32 is less than the axial distance between the rod stop regions 66 and 67.

[0092] Figure 15 A device 260 is shown, which differs from the device 160 only in the region of the stop element 91. The stop element 91 of the device 260 is designed as a solid structural body, whereas the stop element 91 of the device 160 is designed as a bent punched part.

[0093] Figure 16 The device 260 is shown along the Figure 15 The longitudinal section along the cutting line XVI-XVI is shown in detail in FIG. 2 , and the stop element 91 of the device 260 is shown in FIG. Figure 17 It is shown in a three-dimensional single figure.

[0094] The stop element 91 of the device 260 is configured with a blind hole 103, into which the actuating rod 32 engages. Furthermore, the stop element 91 of the device 260 rests against the two carrier middle sections 68E, 69E and has a stop surface 104 facing the actuating element 31. The stop surface 104 is the end surface of the two finger-like regions 98, 99 that extend toward the actuating element 31.

[0095] The finger-shaped regions 98 , 99 are designed with lateral engagement regions 100 , 101 , with which the stop element 91 respectively engages in a recess 102 , 106 of the carrier center sections 68C, 69C and is thus fixedly connected thereto.
