Automobile drive shaft is through shaft tube, telescopic sleeve and universal joint three important components, cooperate with each other to work. Is a universal transmission shaft transmission shaft can transfer the power shaft, for the front engine, rear wheel drive car is to put the rotation to the main reducer shaft transmission, it can be a several day, between section and section are connected by a universal joint, universal joint is the key of automobile transmission shaft parts, is responsible for driving and responsible for steering between front axle and half axle and the wheel. The traditional structure of the transmission shaft expansion sleeve is spline sleeve and flange fork welding together, spline shaft welding on the transmission shaft tube.

Automobile drive shaft is an important connecting part in automobile mechanical system. What is the working principle of automobile drive shaft? Here's a look:

Automobile drive shaft is generally a kind of circular parts that can be connected or assembled, and can move and rotate. It is generally made of alloy steel with light and good torsional resistance. In terms of composition, it is usually composed of shaft tube, expansion sleeve and universal joint. Automobile drive shaft is a high speed, less support of the rotating body, its dynamic balance is very important, the general drive shaft before leaving the factory must enter the action balance test, and has been adjusted on the balance machine.

Automobile drive shaft as an important part of the transmission of power in the automobile transmission system, it can together with the gearbox, drive axle will transfer the power of the engine to the wheel, so that the car has a driving force. Usually special car drive shaft is mainly used in tank cars, refueling vehicles, sprinklers, sewage trucks, suction trucks, fire trucks, high-pressure cleaning vehicles, road wreckers, aerial work vehicles, garbage trucks and other models.
