Definitions
- the present invention relates to a shift drum assembly with a parking lock arrangement for a shift device of a transmission unit, in particular for motor vehicles, with a shift drum body which is rotatable about an axis of rotation, and with egg ner parking lock assembly for immobilizing the motor vehicle. Furthermore, the present invention relates to a transmission unit for a motor vehicle, with a switching device for shifting gears, the switching device having a Wegwal zen arrangement and a parking lock arrangement.
- Switching devices for transmissions are known, for example, from DE 196 55 083 B4 and WO 97/02 963 A2.
- Parking lock arrangements of this type are generally known from DE 10 2009 018 122 A1, DE 10 2012 017 817 A1, DE 10 2014 102 831 A1, DE 10 2014 104 575 A1, for example. These serve to immobilize the vehicle in a motor vehicle transmission, in particular in an automated motor vehicle transmission.
- the shaft is preferably an output shaft of the transmission, which is in direct operative connection with the driven wheels of the motor vehicle. In the locked position, rotation of the shaft is prevented and the vehicle cannot roll away.
- a draw key is axially displaceably mounted on the transmission housing, which releases the parking lock pawl in a release position and is pulled to set up the lock position between a housing section and an actuation section of the parking lock pawl, in this way a pawl in relation to the housing Realize positive locking position for the parking lock pawl, in which the ratchet engages the parking lock toothing.
- actuating mechanisms are formed in the form of cam elements which are fixed on a shaft arranged parallel to the pawl axis of the parking lock pawl.
- the actuation mechanism can have an interface to a manual gear lever in the interior of the motor vehicle, so that the parking lock mechanism is actuated when it is moved into a position “P”.
- actuators can be hydraulic actuators, but can also contain electromechanical actuators such as shift rollers.
- the hybridization of transmissions in particular creates new challenges for the shifting devices.
- a shift drum assembly for a Wegvor direction of a transmission unit, in particular for motor vehicles, with a Wegwal zenkMechs, and a shift element
- the shift drum body is rotatable about an axis of rotation and has a circumference of the outer surface extending second circumferential shifting contour
- the switching contour is formed in an axial and / or radial direction, in which the switching element engages, which is displaceable by rotating the shift drum body by means of the shift contour in the axial direction of the shift drum body, and with a parking lock system with a parking lock wheel, a parking pawl and an actuating mechanism , wherein the actuating mechanism is coupled to the switching element in such a way that at a predetermined switching angle an adjustment of the parking lock pawl from a release position (FP) to the locked position (SP), in which we achieve immobilization of the motor vehicle d, can be brought about
- the switching roller arrangement comprises a switchable restraint system which is adjustable
- a “park-by-wire” actuation for a parking lock system can be implemented in a simple manner.
- the actuation of the parking lock system is achieved by axially displacing the shift element in the circumferential shift contour of the shift drum body.
- the parking lock system can only be switched into the parking position if this is desired. This is achieved by integrating a switchable restraint system for the parking lock pawl of the parking lock system.
- the parking lock pawl is always in a pre-tensioned position for “locking”, but is kept away from the parking lock wheel. If necessary, the switchable restraint system is activated and the pawl is unlocked and pivoted in the direction of the parking lock wheel for the purpose of positive engagement in the toothing.
- the switchable restraint system is preferably kinematically coupled to a switch stop. This can be activated as required and / or in a predefined switching angle / switching angle range in an activation position in such a way that the rotation of the switching drum body is blocked in the parking position.
- the parking position simultaneously corresponds to a reference angle position in which the switching angle is referenced.
- the shift stop comprises a reference element and a stop element.
- stop element is about an axis that runs parallel to the axis of rotation between a “neutral position” in which the stop element is not in engagement with the reference element, and an “activation position” in which the end region is in engagement with the reference element can be brought, is pivotably mounted.
- the pawl is locked in the neutral position of the stop element. In the activation position, the locking of the pawl is released.
- the switchable restraint system advantageously comprises a locking member.
- the locking member is also advantageously attached to a lever which is pivotably mounted.
- the lever is coupled to the stop element so that a pivoting movement of the lever is transmitted to the stop element.
- the pivoting movement of the lever is initiated by an actuator.
- the actuator is preferably a linear actuator.
- a transmission unit for a motor vehicle with a shifting device for shifting gears, the shifting device having a shift drum arrangement of the type according to the invention.

- FIG. 7 shows a detail of the development according to detail D in FIG. 6.
- a drive train 10 for a motor vehicle is shown schematically.
- the drive train 10 has a drive motor 12, which can be formed by a combustion engine or by a hybrid drive unit.
- the drive train 10 includes a clutch arrangement 14, which can be used as a single clutch or as a Double clutch can be realized.
- the clutch arrangement 14 is connected to the drive motor 12.
- the clutch assembly 14 is verbun with a transmission assembly 16 for setting up a plurality of gears, the transmission assembly 16 being shown schematically in FIG. 1 as a multi-step transmission in front of lay construction.
- An output of the transmission arrangement 16 is connected to a differential 18, by means of which drive power can be distributed to driven wheels 20L, 20R.
- the transmission arrangement 16 has a plurality of shift clutches, of which a shift clutch arrangement in the form of a shift clutch assembly is shown schematically at 24 in FIG. 1.
- the clutch arrangement 24 serves alternatively to bring a first or a second wheel set (not shown in more detail in FIG. 1) into the power flow (here a loose wheel of a wheel set is connected to an associated shaft).
- the clutch assembly 24 is shifted by means of a shift sleeve 26 in such a way that either one wheel set or the other wheel set can be placed in the power flow, or a neutral position of the shift drum assembly can be set up.
- the gear assembly 16 includes a switching device 30.
- the Heidelbergvor device 30 is implemented as a shift actuator so that gear steps of the Geretean order 16 can be changed automatically.
- the shift device 30 contains a shift drum assembly 32.
- the shift drum assembly 32 has a shift drum body 34, which is rotatably mounted in two directions of rotation 37a, 37b about an axis of rotation 36, namely rotatable with respect to a housing 38.
- the housing 38 can, for example, a housing the gear assembly 16.
- One or more shift drum shaft receptacles 39 in which a shift drum shaft 40 is housed, can be formed on the housing 38.
- the shift drum body 34 is connected to a drive member 44, on egg ner axial end face thereof.
- the drive member 44 can be formed, for example, by a gearwheel which has an external toothing 46.
- the external toothing 46 of the drive member 44 can, for example, be in engagement with a drive pinion 48 of a shift drum motor 50.
- the shift drum motor 50 can, for example, be an electric motor. By controlling the shift drum motor 50 can the shift drum body 34 can consequently be set in rotation with respect to the housing 38.
- a reference element 64 which is designed as a radially extending pin / pin, is arranged on the outer circumference of the shift drum body 34.
- the reference element 64 defines a radial position of the shift drum body 34 and is used to establish a reference angular position.
- shift drum body 34 On the outer circumference of the shift drum body 34 are a plurality of shift contours in the form of first shift drum grooves 52a, 52b and a second shift contour in the form of a shift drum groove 53 which, as can be seen from FIGS. 2-4, are axially contoured.
- a first shift element 54a, 54b engages in each of the first shift drum grooves 52a, b and also engages the associated shift sleeve 26.
- the switching element has a sliding block which engages in the switching roller groove 52a or 52b. If the shift drum groove 52a, 52b is appropriately designed, rotating the shift drum body 34 leads to an axial offset of the first shift element 54a or 54b and consequently to an axial offset of the shift sleeve 26, which is associated with engaging or disengaging a gear.
- a second shift element 55 engages in the second shift drum groove 53, which enables shifting into a parking position (see FIGS. 6 and 7 at 30 degrees) and, as described in more detail in relation to the other figures, is coupled to an actuation mechanism of a parking lock system 80.
- the parking lock system 80 comprises a parking lock wheel 81 that can be locked via a parking lock pawl 84, an actuating mechanism for adjusting the parking lock pawl 84 from a release position (FP) to the locked position (SP).
- a switchable restraint system is also provided.
- the switchable restraint system can be adjusted between a locking position (AP) in which the parking pawl 84 is locked in the release position (FP) via a locking member and an unlocked Arretierposi tion (eAP).
- the locking member is kinematically connected to a stop element 62 of the shift stop 60. This is shown schematically in FIG. 1 b.
- the stop element 62 is mounted pivotably about an axis A and has a first end region 65 and a second end region 66.
- the second switching element 55 has a first end region 55a and a second end region 55b.
- the first end region 55a is designed with a sliding block 58 which engages in the second shift drum groove 53.
- Rotation of the shift drum body 34 consequently leads to an axial offset of the second shift element 55 into the parking position.
- the park position of the second switching element 55 when the switchable restraint system is activated, it can be moved into the unlocked locking position.
- the parking lock pawl 84 pivots in the direction of the parking lock gear 81 and engages in a tooth gap 87 for the purpose of immobilization.
- the parking lock system 80 is assigned to the input shaft 17 of the transmission arrangement 16 and can be supported on the housing 38 in order to immobilize a motor vehicle equipped with the drive train 10.
- the parking lock system 80 has the parking lock gear 81, which is non-rotatably connected to the input shaft 17.
- a parking lock toothing 82 is formed on an outer circumference of the parking lock mechanism 81.
- the parking lock system 80 also includes a parking lock pawl 84 which is designed to be pivotable about a pawl axis 85.
- the pawl axis 85 is fixed to the housing and is preferably aligned parallel to the input shaft 17.
- the parking lock pawl 84 can be displaced between a locking position SP in the parking position and a release position FP in which a rotation of the input shaft with parking lock gear 81 is possible.
- a ratchet tooth 86 is formed on the parking lock pawl 84, which can engage in a tooth gap 87 of the parking lock gear 82 to set up a locking position SP of the parking lock system 80.
- a Walkerein direction in the form of a leg spring 83 can be provided.
- an actuating mechanism In order to move the parking lock pawl 84 against the spring preload into the locking position, an actuating mechanism is provided.
- This actuating mechanism comprises a suitable preloading unit 100 with a counter-stop 101, such as an actuating rod 102 running parallel to the input shaft with a spring-preloaded preloading cone 103 arranged at the end. Transmission rod 102 is connected to the second end region 55b of the switching element.
- the preload cone 103 rests on the one hand on a radial outer side of the parking lock pawl 84 and on the other hand on its opposite circumferential side on a section of the counter-stop 101.
- the second switching element 55 is attached to an axially displaceable bearing shaft 70.
- the bearing axis 70 runs parallel to the axis of rotation 36.
- the displaceability of the bearing axis 70 is shown by the arrow 71.
- the parking lock pawl 84 is, however, locked in the release position FP by means of the switchable restraint system.
- the switchable restraint system comprises a locking member 88 for this purpose, which locks the parking pawl 84 in the release position.
- the locking member 88 is connected to a lever 68 and engages, for example, on a radial inside of the parking lock pawl 84, in particular on a holding section 89 of the parking lock pawl 84.
- the locking member 88 holds the parking lock pawl 84 in the release position FP, so that unintentional locking of the pawl tooth 86 into a tooth gap 42 can be reliably avoided.
- the parking lock pawl 84 is as above explains the second switching element 55 in the axially displaced parking position. This shift corresponds to a shift along the bearing axis 70 in the direction of the parking lock gear. Due to the spring preload, the preload cone 103 is pushed into the space between the counter-stop 101 and the parking lock pawl 84 and exerts a force on the radial outside of the parking lock pawl 84. The parking lock pawl 84 pivots radially towards the parking lock gear 81, so that the pawl tooth 86 engages in a tooth gap 87.
- the actuator 90 is, for example, a linear solenoid actuator and, via a coupling element 91, can transmit a linear movement to the lever 68, which converts this into a rotary movement.
- the lever 68 is designed to run in a V-shape and is rotatably mounted in the center and is articulated to the actuator 90 by means of its first end region 68a and to the second end region 66 of the stop element 62 by means of its second end region 68b.
- the stop element 62 is mounted adjacent to the second switching element 55 so as to be pivotable between a “neutral position” and an “activation position” about the axis A.
- the stop element 62 is shown in the “activation position”.
- the stop element 62 is designed as a lever with a first end region 65 and a second end region 66.
- the first end region 65 can be brought into engagement with the reference element 64 as a stop in the corresponding “parking position”.
- the stop element 62 is rotated clockwise about the bearing axis 70, so that the first end region 65 is pivoted upwards as much as possible and no engagement with the reference element 64 can take place.
- the actuator 90 is activated and an adjustment movement of the coupling element 91 in the direction of the arrow 92 is effected.
- This adjustment movement leads to a pivoting of the lever 68 and the kinematically coupled stop element 62 counterclockwise into the activation position, whereby the first end area 65 in the corresponding rotational angle position of 30 degrees serves as a switch stop for the reference element 64 and a rotation of the switch roller body 34 is blocked.
- This position as a reference position can be used for referencing the rotational position of the shift drum body 34 and is at the same time the parking position.
- the first reference position corresponds to the parking position, which is shown in FIGS. 6 and 7.
- FIG. 6 shows a schematic representation of a development of the shift drum body 34 in the area of two first shift drum grooves 52 and the second shift drum groove 53.
- the shift drum grooves / shift contours 52a, 52b, 53 extend around the entire circumferential section of the shift drum body 34 (360 Degrees), so that the shift drum body 34 can be rotated endlessly in a first direction of rotation and a second direction of rotation 37.
- the first shifting element 54a which in the present case is assigned to gear steps 3 and 2, engages in the first of the first shift drum grooves 52a.
- the first shift element 54b which in the present case is assigned to gear steps 4 and 1, engages in the second of the first shift drum grooves 52b.
- the shift drum grooves / shift contours 52a, 52b 53 each have a neutral line 57a, 57b.
- the second shift element 55 which can be adjusted between a neutral position and the parking position, engages in the second shift drum groove 53.
- the shifting contour embodied as shifting roller groove 53 comprises a first shifting section which is assigned to a reference angle which, in the exemplary embodiment, is 30 degrees.
- a reference angle which, in the exemplary embodiment, is 30 degrees.
- the parking position and the reference position are reached at 30 degrees. This is indicated by the representation of the sliding block 58 of the second switching element 55.
- an axial displacement of the second switching element 55 begins at approximately 0 degrees.
- the axial displacement in the park position is ended. Starting from the Parkpositi on, the axial displacement of the second switching element 55 in the direction of the neutral position back to about 60 degrees is effected.
- the first shift element 54a is in a position shifted to the right, so that gear stage 2 is engaged.
