Abstract

The invention belongs to the technical field of vehicles, and particularly relates to a differential mechanism, a control method thereof and a vehicle with the differential mechanism. The differentialmechanism comprises a power input gear, a differential mechanism shell, two planet gears, two side gears, two half shafts and a hydraulic locking device, wherein the power input gear is connected tothe outer side of the differential mechanism shell, the differential mechanism shell and the power input gear coaxially rotate, the two planet gears are connected to the inner side of the differentialmechanism shell, the two planet gears are located between the two side gears, the two side gears mesh with the two planet gears correspondingly, the two side gears are coaxial with the power input gear, the two side gears are connected to the two half shafts correspondingly, the two half shafts penetrate through the differential mechanism shell in the mode of being capable of rotating relative tothe differential mechanism shell, and the hydraulic locking device is arranged on the two half shafts.

Description

technical field [0001] The invention belongs to the technical field of vehicles, and in particular relates to a differential gear, a control method thereof, and a vehicle equipped with the same. Background technique [0002] The differential is primarily used to allow the left and right drive wheels of a vehicle to turn at different speeds. When the vehicle is turning or driving on an uneven road, the differential makes the left and right driving wheels roll at different angular velocities to ensure pure rolling between the driving wheels on both sides and the ground, thereby avoiding the increased wear of the car tires and the power of the car. Increased consumption and deterioration of steering and braking performance. [0003] The existing differential is usually equipped with a locking device. The locking device is used to lock the left and right half shafts of the differential so that the left and right half shafts rotate coaxially. When the driving wheel on one side o...
