The structure of an automobile driveshaft is made up of a shaft tube, telescoping sleeve and universal joints. The combination of the universal joints and the driveshaft is known as the universal joint drive.
Shaft tube
1、In order to reduce the friction and wear when the shaft moves, its use is the same as the bearings, the cost is lower, but the friction resistance is larger, so it is only applicable to certain parts.
2、The sleeve is mostly placed in the shaft and support structure, very close to the support structure, only the shaft can rotate on the sleeve.
3、When assembling the shaft and sleeve, a lubricant is added between them to reduce the friction generated when they rotate.
Telescopic Sleeve
1、The telescopic sleeve can automatically adjust the distance change between the transmission and the drive shaft.
2、The new drive shaft welds the spline sleeve and drive shaft tube together, and the spline shaft and flange fork are made into one piece.
3、Rectangular tooth spline is changed to large pressure angle involute short tooth spline, which not only improves the strength, but also facilitates the extrusion molding, and adapts to the needs of high torque working conditions.
4, in the expansion sleeve and spline shaft tooth surface, the whole impregnated with a layer of nylon material, increase wear resistance and lubrication, reduce the impact load on the drive shaft damage, improve the buffer capacity.
Universal joint
1, universal joint is to ensure that the transmission output shaft and drive axle input shaft of the two axis of the angle of change, and to realize the two shafts of equal angular velocity transmission.
2, universal joints are universal joints, is the realization of power transmission variable angle machine, for the need to change the position of the direction of the drive shaft, it is the automobile drive system in the universal transmission of the "joint" parts;.
3、The universal joint is a component that changes the direction of power transmission, it acts somewhat like the joints of human limbs, allowing the angle between the connected parts to change within a certain range, its wear and deformation is light enough to produce noise and vibration, and heavy enough to interrupt the transmission;.
4, the rear-drive car universal joint transmission form are used double universal joints, that is, there is a universal joint at both ends of the drive shaft, its role is to make the angle of both ends of the drive shaft is equal, so as to ensure that the output shaft and the input shaft of the instantaneous angular velocity is always equal; the drive shaft is an important component of the automobile transmission system to transfer power, its role is to transfer the engine power with the transmission and drive axle to the wheels to make the car to generate the drive force.
Summary：
The structure of an automobile driveshaft is made up of a shaft tube, telescoping sleeve and universal joints. The combination of the universal joints and the driveshaft is known as the universal joint drive.
