Differential Model SolidWorks, 3D Exported

The differential is a mechanism that enables the left and right (or front and rear) drive wheels to rotate at different speeds. It mainly consists of the left and right half shaft gears, two planetary gears and the gear carrier. The function is to make the left and right wheels roll at different speeds when the car is turning and driving or driving on uneven roads, i.e. to ensure the pure rolling motion of both driving wheels. The differential is installed to adjust the speed difference between the left and right wheels. In four-wheel drive, in order to drive 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 in a curve, so in order to make the car rotate at the same speed in a curve, it is necessary to add an intermediate differential to adjust the speed difference between the front and rear wheels.
