Casting: differential housing
The differential housing is a mechanism that allows the left and right drive wheels to rotate at different speeds. Its function is to adjust the speed difference between the left and right wheels.
When a car is turning or driving on uneven roads, its presence can cause the left and right wheels to roll at different speeds, ensuring pure rolling motion of the driving wheels on both sides. Especially during four-wheel drive, in order to drive all four wheels, it is recommended to connect all the wheels together. If the four wheels are mechanically connected, the car cannot rotate the curve at the same speed when driving on the same track. To ensure that the speed of the curve is basically the same, an intermediate differential housing needs to be added to adjust the speed difference between the front and rear wheels.
The differential housing is composed of planetary gears, planetary carriers, side gears, and other components.
The material of the differential housing is one of the important factors affecting the performance of the differential. Common materials include aluminum alloys, steel, synthetic materials, and cast iron, each with its own advantages and disadvantages, and manufacturers need to choose according to actual needs. After selecting materials, it is also necessary to optimize the design in conjunction with other components to ensure the normal operation of the differential.
