  • Patent number: 11486468
    Abstract: A gearwheel for a gear system for a planetary gear system of a chassis assistance system. The gearwheel is divided into at least a first spur gear and a second spur gear which are spaced apart from one another along a common rotational axis. The gearwheel has, in addition, an open spring ring with a first end, which is supported in a circumferential direction against the first spur gear, and a second end, which is supported in the direction opposite to the circumferential direction against the second spur gear in such manner that by rotating the spur gears, relative to one another about the common rotational axis, the spring ring can be stressed in order to exert a restoring torque on the spur gears. A recess is formed on at least one of the spur gears for holding part of the spring ring.

  • Patent number: 11454319
    Abstract: In a vehicle parking lock mechanism, a parking pawl hinders rotation of a parking gear by engaging with the parking gear, and a lock member establishes a parking lock state by bringing the parking pawl closer to the parking gear and moving to a lock position. The cam mechanism includes a pair of a first roller and a second roller provided on the lock member. When the lock member is moved from an unlock position to the lock position, the first roller brings the parking pawl closer to the parking gear to be engaged with the parking gear and the second roller restricts the lock member from displacing in a direction away from the parking pawl. An outer peripheral surface of at least one of the first roller and the second roller includes a fixing portion that protrudes toward the lock position.

  • Patent number: 11441678
    Abstract: A vehicle parking lock mechanism includes a parking gear, a parking pawl, a lock member, and a support member. The parking pawl is meshed with the parking gear to hinder rotation of the parking gear. The lock member moves the parking pawl closer to the parking gear via a cam mechanism as the lock member is moved toward the locked position, to establish a parking locked state in which rotation of the parking gear is hindered by the parking pawl. The support member is provided with a guide portion guiding movement between a locked position and an unlocked position. The cam mechanism moves the parking pawl closer to the parking gear to be meshed therewith. A stopper is disposed on the lock member, to be engaged with the support member by taking a projecting posture in which the stopper projects toward the support member in the parking locked state.
