Abstract:
The present specification discloses a differential mechanism and a vehicle. The differential mechanism includes a shell. A left half axle gear, a right half axle gear, a planet wheel and a planet wheel axle are disposed in the shell. The planet wheel is rotatably mounted on the planet wheel axle and meshes with the left half axle gear and the right half axle gear. A power engagement device includes a first engagement portion and a second engagement portion. The first engagement portion is connected with the left half axle gear or the right half axle gear, and the second engagement portion rotates synchronously with and moves axially relative to the shell. An engagement portion drive device includes a drive pin and a drive portion. The drive portion is configured to drive the drive pin to drive the second engagement portion close to the first engagement portion along an axial direction.
