Parking lock arrangement with a fail-safe actuator and a method for actuating such a parking lock arrangement and drive train with a parking lock arrangement with a fail-safe actuator

摘要

Parking lock arrangement (1), comprising a drive device (2), a worm wheel (3) with a radially circumferential helix contour (4) attached to the end face, an actuator (5) with an actuator pin (6) and an actuator roller (7), with a rotational movement of the worm wheel (3) about a first axis of rotation (8) causes the actuator roller (7) to roll on the helical contour (4), whereby an axial movement of the worm wheel (3) is generated, whereby a locking cone (9 ) is engaged or disengaged against a pawl (10), which results in the pawl (10) being engaged or disengaged in a corresponding contour of a parking lock wheel (11), characterized in that an actuator roller axis of rotation (12) and a tangent ( 13) of the worm wheel (3) are at an angle α ≠ 90 ° to each other.
