The differential is an important component of the automobile transmission system. It mainly consists of the differential case, the spider gear shaft, two spider gears, two side gears, composite thrust washers, and other components.
Its function is to balance the difference in the tracks of the left and right wheels through different rotation speeds when the car turns, and achieve automatic adjustment. When the car turns left, the track of the wheel presents an arc, with the center of the arc on the left, while the track of the right wheel is longer. If the rear wheel axle is made into an integral part, the speed difference between the two wheels will not be achieved, and automatic adjustment will not be achieved.
Three Main Functions of Differential
1. Transmit the power output of the engine to the wheels;
2. Divide the torque increased by the main reducer into two and distribute it to the left and right half shafts;
3. As the main reducer of the car, it reduces the speed of the transmission system before the power is transmitted to the wheels, transmits the power to the wheels, and allows the wheels on both sides to rotate at different speeds.
The function of the differential is to allow the left and right wheels of the car to rotate at different speeds when turning to achieve automatic adjustment. When the car turns left, the center of the arc is on the left, so the track of the left wheel is shorter and needs to rotate at a lower speed, while the track of the right wheel is longer and needs to rotate at a faster speed. To achieve this goal, the differential must distribute the power output of the engine to the left and right half-axles, and transmit it to the wheels at different speeds, so as to balance the difference in the tracks of the left and right wheels. If the rear axle is made as a whole, this function will not be achieved.
The role of the differential can also divide the torque increased by the main reducer into two and distribute it to the left and right half-axles, so as to achieve more efficient transmission. In addition, as the main reducer of the car, the differential can also reduce the speed of the transmission system before the power is transmitted to the wheels, transmit the power to the wheels, and allow the wheels on both sides to rotate at different speeds. This not only improves the driving efficiency of the car, but also ensures the stability of the vehicle.
