Abstract:
1. A parking lock arrangement for a motor vehicle gearbox, comprising: a parking lock cog, which is fixed to a shaft of the motor vehicle gearbox rotatable about a first axis, a parking lock pawl, which is supported so that the pawl pivots about a second axis, an actuating mechanism, by means of which the parking lock pawl is pivotable into a locking position, in which the parking lock pawl meshes with the parking lock cog, and a release mechanism, by means of which the parking lock pawl is pivotable out of the locking position into a release position, in which the parking lock pawl is decoupled from the parking lock cog, wherein the actuating mechanism has a cam arranged on an actuating shaft which turns by means of an actuating member, which is supported so that the cam is pivotable about a third axis and which in a first cam position holds the parking lock pawl in the locking position, wherein the release mechanism has a guide device for the parking lock pawl arranged on the actuating shaft, the parking lock pawl being positively guided against the guide device at least in the direction of pivoting action from the locking position into the release position, wherein the guide device has a recess in which a drive member of the parking lock pawl is positively guided, at least in sections, wherein the cam defines a cam surface that is axially separate from a surface defined by the recess with respect to the actuating shaft, and wherein in the locking position the parking lock pawl is held against the separate cam surface so that a positive interlock is established between the separate cam surface and the parking lock pawl.
