The automotive drive shaft is generally a circular component that can be connected or assembled, and can also move and rotate. It is generally made of alloy steel tubes that are torped with torque, usually by the shaft tube, telescopic sleeve and universal Composition. The automotive drive shaft is a high speed, less supported rotating body. Its dynamic balance is important. The general drive shaft must be dynamically balanced before the factory, and adjusted on the balancing machine.

The automotive drive shaft is an important component of the driving force in the automobile transmission system, which can pass the power of the engine to the wheel with the gearbox, drive bridge, to cause the car to generate a driving force. Usually dedicated automotive drive shafts are mainly used in tankers, fuel cars, sprinkles, suction vehicles, suction trucks, fire trucks, high-pressure cleaning vehicles, road wreckers, high-altitude operation vehicles, garbage trucks and other models.

The automotive drive shaft is working through three important components of the axis, expansion and universal joints, mutual cooperation. The transmission shaft is a shaft that can transmit power in the drive shaft of the transmission, which drives the front engine rear wheel driven to the axis of the transmission to the main speed, which can be several sections, sections The knot can be connected by a universal joint, and the universal joint is a key component on the automotive drive shaft, which is responsible for driving and responsible between the half-axis and the wheels of the steering.

Conventional structure of the drive shaft telescopic sleeve is welded to the flange and the flange, and weld the spools on the drive shaft tube. A new type of transmission shaft changes the traditional structure, and welcomes the spline sleeve to the drive shaft tube, and the splice shaft is integrated with the flange, and the drive shaft adds a tube shape outside the flange spline. The sealing protective sleeve is provided with two polyurethane rubber oil seals in the end of the protective sleeve.

Most of the shafts are made of copper, but there are also plastic shafts, and the shaft sleeves are placed in the shaft and the support structure, and it is very close to the support structure, only the shaft energy is rotated on the bushing, in assembly When the shaft is coupled to the bushing, the lubricant is added to reduce the friction generated during rotation.

From the above-mentioned car drive shaft structure, we can see that the car drive shaft can be divided into lids, cover, cover, universal hollow, grease, expansion, sliding split groove, oil seal, oil seal cover, traditional axis Pipes.

The above is about some related introductions on the working principle and structural map of the automobile drive shaft. For this important connection component of the car, are you more familiar!
