Description

Technical Field

[0001] The utility model belongs to the technical field of automobile transmission, and relates to an automobile driving motion differential. Background Art

[0002] The function of the differential is to make the left and right wheels roll at different speeds when the car is turning or driving on uneven roads, that is, to ensure that the driving wheels on both sides are in pure rolling motion. The differential is installed to adjust the speed difference between the left and right wheels. In four-wheel drive, in order to drive the four wheels, all the wheels must be connected. If the four wheels are mechanically connected together, the car cannot rotate at the same speed when driving on a curve. In order to make the car's rotation speed basically consistent when driving on a curve, it is necessary to add a center differential to adjust the speed difference between the front and rear wheels.
