Technical Field

[0002] The planetary gear shaft of the automobile differential is a device that transmits torque to the planetary gears to achieve torque distribution, so that the wheels can achieve differential operation. It is one of the core components of the differential. Through precise cooperation with the planetary gears, it ensures that the left and right wheels can rotate independently and adapt to different road conditions. The differential planetary gear shaft is usually installed on the central shaft of the differential, which may be a cross-shaped or straight-shaped design. The planetary gears mesh with the half-shaft gears on both sides, and the rear end of each gear assembly is equipped with a thrust washer to ensure smooth operation. When the vehicle turns or the wheels are subject to different ground resistance, the planetary gear shaft realizes differential drive of the wheels on both sides through a combination of rotation and revolution.
