Do you know what a car drive shaft is?

The structure of the automobile drive shaft is composed of a shaft tube, a telescopic sleeve and a universal joint. The combination of the universal joint and the drive shaft is called a universal joint drive.

shaft tube
1. In order to reduce the friction and wear when the shaft moves, its purpose is the same as that of the bearing, the cost is lower, but the friction resistance is larger, so it is only suitable for certain parts.
2. The shaft sleeve is mostly placed in the shaft and the support structure, which is very close to the support structure, and only the shaft can rotate on the shaft sleeve.
3. When assembling the shaft and sleeve, add lubricant between the two to reduce the friction generated when they rotate.

Telescopic sleeve
1. The telescopic sleeve can automatically adjust the distance between the transmission and the drive shaft.
2. The new type of transmission shaft welds the spline sleeve and the transmission shaft tube together, and the spline shaft and the flange fork are made into one body.
3. The rectangular tooth spline is changed into a large pressure angle involute short tooth spline, which not only improves the strength, but also facilitates extrusion forming, which adapts to the needs of large torque working conditions.
4. On the expansion sleeve and the tooth surface of the spline shaft, a layer of nylon material is impregnated as a whole, which increases the wear resistance and lubricity, reduces the damage to the transmission shaft caused by the impact load, and improves the buffer capacity.

Universal Joint
1. The universal joint is to ensure the change of the angle between the two axes of the transmission output shaft and the drive axle input shaft, and to realize the equal angular velocity transmission of the two shafts.
2. The universal joint is a universal joint, which is a machine that realizes the variable angle of power transmission. It is used to change the position of the drive shaft direction. It is the "joint" part of the universal transmission in the automobile drive system;.
3. The universal joint is a component that changes the direction of force transmission. Its function is a bit like a human limb joint. It allows the angle between the connected parts to change within a certain range. Its wear and deformation will cause abnormal noise and vibration. Heavy will interrupt the transmission;.
4. The universal joint transmission form of rear-drive vehicles adopts double universal joints, that is, there is a universal joint at both ends of the drive shaft. Its function is to make the angles of the two ends of the drive shaft equal, so as to ensure the instantaneous speed of the output shaft and the input shaft. The drive shaft is an important part of the transmission power in the automobile transmission system. Its function is to transmit the power of the engine, the transmission and the drive axle to the wheels, so that the car generate driving force.
