  • Publication number: 20260318411
    Abstract: A parking lock device includes a first fastening element, a carrier element arranged to be fastened to a housing by the first fastening element, a locking pawl, an actuating element and a stop element. The locking pawl is pivotable on the carrier element between a locked position where the locking pawl is latched with a rotary component, and a release position in which the locking pawl is decoupled from the rotary component. The actuating element is axially displaceable between a first axial position where the actuating element deflects the locking pawl into the locked position, and a second axial position where the locking pawl is in the release position. The stop element is formed separately from the carrier element and arranged to limit axial displacement of the actuating element. The stop element can be fastened to the carrier element or the housing by a second fastening element.

  • 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.

  • Patent number: 10704689
    Abstract: A motor vehicle parking lock includes a locking pawl, an actuator shaft, a pawl actuating element and a crank mechanism. The locking pawl is pivotable about a first rotational axis and includes a pawl tooth configured for engagement in a recess of a locking tooth system in a positively locking manner. The actuator shaft is rotatable about a second rotational axis to actuate the locking pawl and reversibly bring the pawl tooth into engagement with the recess. The pawl actuating element is linearly moveable along a translation axis to pivot the locking pawl. The crank mechanism converts rotary motion of the actuator shaft into linear motion of the pawl actuating element. The crank mechanism includes a connecting rod with an articulation point at the pawl actuating element, and a joint that connects the connecting rod and a crank. The joint is arranged between the pawl tooth and the articulation point.
