Abstract

A parking lock arrangement for a motor vehicle, said parking lock arrangement comprising a locking device (1) operable between a released position and a locked position, wherein said locking device ( 1) Designed to immobilize the motor vehicle in the locked position, wherein the locking device (1) has a parking pawl (3) pivotable about a pawl axis (2) and has a An operating device (4) for operating the locking device (1), wherein the operating device (4) has a lever (5) which is pivotally supported about a pivot point (6) and which A lever is coupled to the locking device (1) such that by pivoting of the lever (5) the parking pawl (3) can be pivoted between the released position and the locked position between operating the locking device (1), wherein the operating device (4) comprises a pin (8) on the end side and eccentrically arranged on the shifting drum (7) as a driver, wherein the pin ( 8) Arranged adjacent to the lever (5) so that when the shift drum (7) turns, the lever (5) passes through in the first corner section of the shift drum (7) Said pin (8) is driven to pivot.

Description

Technical field [0001] The present invention relates to a parking locking device for motor vehicles, including a locking device, the locking device may operate between the release position and the locking position, wherein the locking device is constituted for, in the locking position so that the motor vehicle does not move, and has an operating device for operating the locking device. Background [0002] Parking locks are typically used in automatic transmissions such as automatic torque converters, automated shift transmissions or dual-clutch transmissions. [0003] The locking device of such a parking lock device typically comprises a parking lock wheel, the parking lock wheel having a tooth part, the tooth part having teeth and gap. The parking lock wheel is usually fixed to the output or input shaft of the transmission, but it can also be fixed to the components of the differential. Therefore, the parking lock wheel is coupled directly to the output of the motor vehicle. In ...
