The automobile transmission shaft works through three important components: shaft tube, expansion sleeve and universal joint. The transmission shaft is the shaft that can transmit power in the transmission shaft of the universal transmission device. For vehicles with front engine and rear wheel drive, it is the shaft that transmits the rotation of the transmission to the main reducer. It can be several joints, and the joints can be connected by universal joints. Universal joints are the key components of the automobile transmission shaft, between the front axle half shaft and the wheels, which are responsible for driving and steering. The traditional transmission shaft expansion sleeve is welded with the spline sleeve and the flange fork, and the spline shaft is welded on the transmission shaft pipe.

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

Automobile transmission shaft is generally a round part that can be connected or assembled, and can move and rotate. It is generally made of light alloy steel pipe with good torsional resistance. In terms of composition, it is usually composed of shaft tube, expansion sleeve and universal joint. The automobile transmission shaft is a rotating body with high rotation speed and less support. Its dynamic balance is very important. Generally, the transmission shaft is subject to dynamic balance test before delivery and adjusted on the balancing machine.

As an important part of transmitting power in the automobile transmission system, the automobile transmission shaft can transmit the power of the engine to the wheels together with the gearbox and drive axle, so as to generate driving force for the automobile. Usually, special automobile transmission shafts are mainly used in oil tank trucks, fuel trucks, sprinkler trucks, dirt suction trucks, septic suction trucks, fire trucks, high-pressure cleaning trucks, road wreckers, aerial work trucks, garbage trucks and other vehicles.
