Embodiment Construction

[0039] figure 1 A parking lock 10 for an automatic transmission of a passenger car is shown partially. Parking lock 10 included in figure 1 Unrecognizable locking elements, for example in the form of a parking pawl, and a drive train locking gear for parking, which is connected in a rotationally fixed manner to a transmission element that is rotatable about an axis of rotation and is secured against rotation by this transmission element connected to the drive train of the car. The locking part (parking lock pawl) is here displaceable between at least one release position and at least one locking position. In the locked position, the blocking element cooperates with the drive train locking gear when parked, so that the transmission element and thus the drive train are secured against rotation.

[0040] In order to realize the co-operation of the locking element and the drive train locking gear for parking, the locking element engages, for example, in a recess on the outer pe...

Abstract

The invention relates to a parking lock (10) for a gearbox, in particular an automatic gearbox, of a motor vehicle, having at least one locking member adjustable between at least one release position and at least one locking position, by means of which locking member in the locking position at least one gear element of the gearbox is locked against rotation, and having a holding device (34) having at least one safety position, by means of which holding device the locking member is secured in the at least one safety position of the holding device (34) against a movement out of the release position into the locked position, wherein the holding device (34) has at least one second safety position, in which the locking member is secured by means of the holding device (34) against a movement out of the locked position into the release position.

Description

technical field [0001] The invention relates to a parking lock for a motor vehicle transmission, in particular an automatic transmission, according to the preamble of claim 1 . Background technique [0002] Such a parking lock for a motor vehicle transmission, in particular an automatic transmission, is known from DE 10 2005 002 446 A1. The parking lock comprises at least one locking part which can be actuated by an adjusting drive and which is acted upon in the locked position by spring force. The parking lock also includes a holding device arranged next to the adjusting drive and acting on the locking part by means of the locking element, by means of which holding device the locking part can be held in its unlocked position independently of the adjusting drive. The locked position is the locked position in which at least one transmission element of the transmission is locked against rotation. The unlocked position is the released position in which the transmission elemen...
