Problems solved by technology

It is conceivable to transfer the adjustment work from the park lock wheel / pawl interface to the lock pawl actuation mechanism interface of the lock pawl, such as an electric motor, but this creates the disadvantage that a park lock with an actuator Units are not available as pre-fabricated modules, which increases installation effort

Embodiment Construction

[0031] figure 1 A parking lock device 10 is shown with a locking pawl 12 which can be rotated about an axis of rotation 14 . As the locking pawl 12 rotates, the ratchet 16 integrally formed therewith moves substantially in a radial direction 19 relative to the main drive shaft (not shown). The parking lock device 10 is intended to be installed in the vehicle transmission of a motor vehicle and immobilizes a parking lock wheel (not shown) connected in a rotationally fixed manner to the main drive shaft. For this purpose, the parking lock wheel has a locking tooth system arranged on its outer circumference, into which the ratchet 16 can be locked in a form-fitting manner.

[0032] The locking pawl 12 is held by a return spring 28 which prevents the locking pawl from inadvertently locking on the parking lock wheel due to gravity in an unloaded state.

[0033]The parking lock device 10 also has a first housing wall 20 and a second housing wall 22 which are arranged as plate part...

Abstract

The invention relates to a parking lock (10), having a parking lock housing (20), a locking pawl (12) which has a ratchet (16) which can be locked in a parking lock wheel (56) and a pawl profile (44) which is arranged on the rear side with respect to the ratchet (16), an actuating unit (24) which loads the pawl profile (44) in the case of the engaging of the parking lock (10) and rotates the locking pawl (12) here about a rotational axis (14) relative to the parking lock housing (20), and a supporting element (18), on which the actuating unit (24) is supported at different positions in the engaged state (P) and in the disengaged state (nP) of the parking lock. The supporting element (18) is connected to the parking lock housing (20) in a manner which is affected by play. Furthermore, the invention relates to an assembly method for said parking lock, and to a vehicle transmission with a parking lock.

Description

technical field [0001] The invention relates to a parking lock device according to the preamble of claim 1 , a method for its assembly, and a transmission with such a parking lock device. Background technique [0002] A parking lock device is known, for example, from DE 10144063 A1. It describes a parking lock device in an automatic transmission of a motor vehicle, which has a locking ring with a locking groove arranged on a drive shaft. When the device is in the locked state, the pawl engages with the locking groove through the pivotable gear selector lever and the link connected thereto. The connecting rod has rollers at its ends, wherein the second roller guides the connecting rod in the L-shaped guide. The guide plate is fixed in the housing of the automatic transmission. When the connecting rod moves longitudinally, the second roller rolls on the guide plate. Thus, the guide plate comprises side walls and horizontally extending walls. The horizontally extending wal...
