Abstract

A parking lock arrangement for a drive train of a motor vehicle includes a controllable locking mechanism and an unlocking mechanism. The controllable locking mechanism includes a spindle drive with a spindle shaft rotationally drivable about a spindle axis, an actuator for rotating the spindle shaft and a positioning element movable by rotating the spindle shaft for actuating a blocking element. The blocking element acts at least indirectly on a drive element in a blocking or releasing manner. The unlocking mechanism includes an unlocking element and a manually operable control element. The unlocking element is movable via the control element from a normal position, in which the unlocking element is spaced apart from the spindle shaft, into an engagement position, in which the unlocking element is coupled in torque-transmitting manner to the spindle shaft for forced releasing of the locking mechanism.
