Parking brake assembly for a transmission in a vehicle with an electric actuation of the parking brake via a mechanism and with an emergency actuator with a lift magnet on a spring accumulator for application of the parking brake. The spring accumulator has a pawl rotatable about a pivot point connected to the lift magnet and a mass element connected to the pawl and rotatable about a second pivot point.

A parking mechanism arrangement for a motor vehicle transmission has a housing and a shaft supported so that it can rotate in relation to the housing. A parking mechanism gear is rotationally fixed to the shaft and comprises a parking mechanism tooth system. A parking mechanism pawl is supported so that it can pivot about a pawl axis in relation to the housing and comprises a pawl tooth, which is capable of engaging in a tooth space of the parking mechanism tooth system in order to establish a locked position. An actuating mechanism comprises an actuating element, which acts upon an actuating portion of the parking mechanism pawl in order to pivot the parking mechanism pawl from a release position into the locked position. The actuating element is embodied as a cam ring, which is arranged concentrically with the shaft and which comprises a cam portion, which acts on the actuating portion in order to establish the locked position.

Parking mechanism arrangement for a motor vehicle transmission

A parking lock arrangement for a motor vehicle transmission has a housing. A parking lock wheel is connectable to a shaft of the motor vehicle transmission. A parking lock pawl is pivotable between a parking lock position and a release position about a pawl axis mounted on the housing. In the parking lock position, the parking lock pawl is in engagement with the parking lock wheel and prevents the rotation thereof. The parking lock arrangement comprises an actuating mechanism for the parking lock pawl and an actuator arrangement for the actuating mechanism. The actuator arrangement has a control member which is movable between a home position and a parking position and is coupled to the actuating mechanism. An actuating member is coupled to the control member via a releasable coupling device and to the actuating mechanism, wherein the actuating member is furthermore mechanically preloaded in one direction in order, via the actuating mechanism, to press the parking lock pawl into the parking lock position. The coupling device is designed in such a manner that it is releasable by means of an electric release signal.
