  • Parking lock arrangement
    Patent number: 11428317
    Abstract: A parking lock arrangement with an actuating device for engaging and disengaging a parking pawl (10) for interlocking and releasing a parking interlock gear (20) includes an axially movable actuating rod (30) with an axially displaceable actuating element (40) on an end facing the parking pawl (10). During the engagement and disengagement of the parking lock, an actuating contour (41) of the actuating element (40) is in contact with an actuating zone (13) of the parking pawl (10) and with a support contour (51) of a housing-affixed guide element (50). The actuating contour (41) is designed to be rotationally symmetrical with respect to a longitudinal axis (42) of the actuating element (40) and extends along this longitudinal axis (42). The actuating contour (41) is a circular arc as viewed in the direction of the longitudinal axis (42) of the actuating element (40).
