Abstract

The invention relates to a parking lock (1) for a transmission of a motor vehicle with a parking lock wheel (2), comprising a locking pawl (3) designed for Cooperates with the toothing of the parking lock wheel (2) to lock the rotation of the parking lock wheel (2) in the locked position and to release the rotation of the parking lock wheel (2) in the unlocked position , wherein the locking pawl (3) is actuated via a carriage (9) and is pivotably accommodated on a bolt (5) about an axis of rotation (4) on which a guide rod (7) is arranged And the spring element (8), and wherein the carriage (9) is effectively connected with the locking pawl (3) and can move axially along the longitudinal direction of the guide rod (7) to manipulate the locking pawl (3), wherein the guide The element (6) is configured to guide the guide rod (7) and accommodate the spring element (8), wherein the guide element (6) has a housing (10) with a bottom (11), wherein the bottom (11) has a The through-recess (12) of the guide rod (7) is guided, and wherein the spring element (8) bears against the base (11) by means of the first end section.

Description

technical field [0001] The invention relates to a parking lock for a transmission of a motor vehicle, the transmission having a parking lock wheel. Background technique [0002] The parking lock is designed to engage with the aid of a locking pawl into a toothing of a parking lock wheel of a motor vehicle transmission when actuated by the driver of the motor vehicle, in order to prevent the transmission by said engagement of the locking pawl The output shaft that is effectively connected with the parking lock wheel rotates, thereby preventing the motor vehicle from rolling away. [0003] For example, DE 101 44 063 A1 discloses a parking lock for an automatic transmission of a motor vehicle, which has a locking ring arranged on the transmission shaft and in the locked state of the device, in the A pivotably supported pawl engaged in the locking recess. In addition, the parking lock has a likewise pivotably mounted selector lever, which acts on a connecting rod which accommo...
