Patent ID: 10724634

Abstract:
A parking lock device for a motor vehicle including a parking interlock gear and a parking pawl. The parking interlock gear has teeth and tooth gaps, wherein each of the teeth has a first and a second deflecting contour that are counter-revolving and radially increasing from a radial indentation toward a respective tooth flank. The parking pawl includes a ratchet tooth. The parking interlock gear is rotatable about an axis of rotation and the parking pawl is rotatable about or translational along a swivel axis parallel to the axis of rotation. The contours slidingly guide the ratchet tooth to catapult over the tooth gaps in a targeted rotational speed range of the parking interlock gear, the targeted rotational speed range being between a minimum limit speed and a maximum limit speed, such that contact is avoided between tooth flanks of the parking pawl and of the parking interlock gear.
