description

The ordinary symmetrical bevel gear differential is composed of the left and right housings of the differential, two half shaft gears, four planet gears, planet gear shafts, half shaft gear gaskets and planet gear gaskets. Because it has the advantages of simple structure, stable work, convenient manufacture, and reliability for road vehicles, it is widely used in various vehicles.
The drive axle is mainly composed of a main reducer, a differential, a half shaft and a drive axle housing.
The main reducer is generally used to change the transmission direction, reduce the speed, increase the torque, and ensure that the car has sufficient driving force and appropriate speed. There are many types of main reducers, including single-stage, double-stage, two-speed, wheel-side reducers, etc.
1) Single-stage final reducer
A device that achieves speed reduction by a pair of reduction gears is called a single-stage reducer. Its simple structure and light weight are widely used in light and medium-duty trucks such as Dongfeng BQl090.
2) Double-stage final reducer
For some heavy-duty trucks, a larger reduction ratio is required. When a single-stage main reducer is used for transmission, the diameter of the driven gear must be increased, which will affect the ground clearance of the drive axle, so two decelerations are used. Usually called a two-stage reducer. The double-stage reducer has two sets of reduction gears to achieve two reductions to increase torque.
