A lever () for the temporary disengagement of a parking lock () of a vehicle drive unit (). The lever () comprises a fixing piece () for fitting the lever () onto a parking lock shaft (), which extends inside the vehicle drive unit () and serves to actuate the parking lock (). The lever () is a hand lever with a gripping handle (). The gripping handle () is designed to enable a user to apply a manual force for manual actuation of the lever (). When the lever () is fitted on the parking lock shaft () and moved, the parking lock shaft () is moved from an engagement position to a disengagement position. In the disengagement position, by further movement of the gripping handle () into a locking position, the lever () is blocked against a reverse movement out of the disengagement position.

Hand lever to provisionally disengage a parking lock by hand

A transmission parking lock has an actuating rod that is essentially translationally displaceable, which bears an actuating element, and with a locking lever that is essentially rotationally displaceable, bears a locking element For inserting the transmission parking lock through the displacement of the actuating rod, the locking lever is pivotable from a resting position of the same into a locked position in such a manner that the locking element engages in a recess of a gear wheel () allocated to a gear shaft, and with a device that withdraws the actuating element of the actuating rod in the resting position of the same from the locking lever.

Transmission parking lock

A parking lock device of a motor vehicle transmission comprising a transmission housing () with a housing wall (), a parking lock gearwheel (), a parking lock pawl (), a parking lock bolt () for mounting the parking lock pawl () and a blocking element (). A carrier plate () is arranged alongside the parking lock pawl () and is fixed to the transmission housing (), and the parking lock bolt () is held, on one side, by the carrier plate () and, on the other side, by the transmission housing ().
