  • 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.

  • Patent number: 11098799
    Abstract: A parking lock device includes a parking gear, a parking pawl, a parking cam, a solenoid actuator, and a power conversion mechanism. The power conversion mechanism is configured to convert reciprocal motion of the plunger to rotary motion of the parking cam in one direction. When the parking cam rotates, a position of a cam surface of the parking cam that abuts the parking pawl is changed, so as to alternately switch between a locked position where rotation of the parking gear is stopped and an unlocked position where meshing between the parking gear and the parking pawl is canceled. A stroke amount of the plunger is reduced in a range where the parking cam can rotate. In this way, the parking lock device can be downsized. Therefore, mountability of the parking lock device on a vehicle is improved.
