  • Patent number: 11614167
    Abstract: A parking lock has a parking lock housing (20), a locking pawl (12) which has a ratchet (16) that can be locked in a parking lock wheel (56) and a pawl profile (44) arranged on the rear side of the ratchet (16), an actuating unit (24) which acts upon the pawl profile (44) when the parking lock (10) is engaged and thereby rotates the locking pawl (12) about a rotational axis (14) relative to the parking lock housing (20), and a supporting element (18), on which the actuating unit (24) is supported in the engaged state (P) and in the disengaged state (nP) of the parking lock (10) at different positions. The supporting element (18) is connected to the parking lock housing (20) so as to have play.

  • Patent number: 10962113
    Abstract: A parking lock (1) for a motor vehicle, wherein the parking lock (1) has a housing (21), a locking pawl (4) which is arranged such that it can be pivoted about a rotational axis (a) and has a pawl tooth (5) which is configured for engaging in a positively locking manner into a parking lock gear, an actuator (6) for actuating the locking pawl (4), with the result that it can be brought reversibly into engagement with the parking lock gear by way of the pawl tooth (5) of the locking pawl (4), and a movable transmission element which transmits the movement of the actuator (6) to the locking pawl (4). The parking lock (1) has a damping mechanism for the locking pawl or for the movable transmission element.
