Patent ID: 8490770

Claim:
A parking brake assembly for a driveline of a motor vehicle, comprising: a locking mechanism configured to inhibit and release the rotational movement of a shaft in the driveline of a motor vehicle; an actuator configured for actuating the locking mechanism; wherein the locking mechanism comprises a locking element which is linearly movable by the actuator, and a latching element which cooperates with the locking element, wherein the locking element is configured to be transferred into a first axial position in which the latching element assumes a releasing position in which the shaft is rotatable, and wherein the locking element is also configured to be transferred into a second axial position in which the latching element assumes a closing position in which the latching element inhibits a rotational movement of the shaft; an unlocking mechanism for forcibly unlocking the locking mechanism, wherein the unlocking mechanism comprises an unlocking element for rotating the locking element, wherein, in the second axial position, the locking element is configured to be transferred into a first rotational position in which the locking element holds the latching element in the closing position, and wherein the locking element is configured to be transferred into a second rotational position in which the latching element assumes a releasing position.
