Problems solved by technology

Although it is conceivable to transfer the adjustment work from the parking lock gear-lock pawl interface to the lock pawl-lock pawl actuating mechanism interface, it leads to the following disadvantages: the parking lock with its actuating Mechanisms, eg electric motors, cannot be provided as pre-produced modules, which in turn increases the installation effort
This leads to a significant limitation of the function of the parking lock

Embodiment Construction

[0029] figure 1 A parking lock 10 is shown with a locking pawl 12 which is rotatable about an axis of rotation 14 . When the locking pawl 12 rotates, the locking tooth 16 formed integrally therewith moves substantially in a radial direction 19 with respect to the (not shown transmission main shaft). The parking lock 10 is provided for installation in the vehicle transmission of a motor vehicle and brings about the fixing of a parking lock gear 56 which is connected in a rotationally fixed manner to the transmission shaft. For this purpose, the parking lock gear wheel 56 has a locking toothing arranged on its outer circumference, into which locking toothing 16 can be locked in a form-fitting manner.

[0030] The locking pawl 12 is held by a return spring 28 , which prevents unintentional locking of the locking pawl 12 on the parking lock gear wheel 56 in the unloaded state due to gravity.

[0031] The parking lock 10 also has a housing wall 20 which is fastened to the transmi...

Abstract

The invention relates to a parking lock (10) for a motor vehicle transmission, comprising a locking pawl (12) which can be rotated about an axis of rotation (14) and which has locking teeth (16) which are designed to lock a parking lock gearwheel (56) in a locking position and to release the parking lock gearwheel (56) in an unlocking position; a locking cone (52), by means of which the locking pawl (12) can be moved into a locking position; and a guide rod (58) on which the locking cone (52) is arranged in a linearly movable manner. A rotary joint (54) is arranged between the locking tooth (16) and the guide rod (58).

Description

technical field [0001] The invention relates to a parking lock having a locking pawl rotatable about an axis of rotation, the locking pawl having locking teeth which are designed for , the parking lock gear is locked in the locked position and the parking lock gear is released in the unlocked position; the locking cone, via which the locking pawl can be moved into the locking position; and a guide rod on which the locking cone is linearly movable. Background technique [0002] A parking lock is known, for example, from DE 101 44 063 A1. Therein, a parking lock in an automatic transmission of a motor vehicle is described, which has a locking ring with a locking recess arranged on the transmission shaft. By means of a pivotable selector lever and a connecting rod articulated thereon, the pawl engages the locking recess in the locked state of the device. The connecting rod has rollers at its ends, a second of which guides the connecting rod in an L-shaped guide plate. The g...
