The drive shaft is composed of a shaft tube, a telescopic sleeve and a universal joint. The telescopic sleeve can automatically adjust the change of the distance between the transmission and the drive axle. The universal joint is to ensure the change of the angle between the two axes of the output shaft of the transmission and the input shaft of the drive axle, and realize the equal angular speed transmission of the two shafts. The following editor will introduce to you the types of transmission shafts and the content of their use and maintenance. Welcome to read!
Type of drive shaft:
According to elasticity:
According to its important component - the universal joint, the drive shaft can have different classifications. According to whether the universal joint has obvious elasticity in the torsion direction, it can be divided into rigid universal joint drive shaft and flexible universal joint drive shaft.
1. Rigid universal joint: transmit power through hinge connection.
2. Flexing universal joint: The power is transmitted by elastic parts, which has the function of buffering and damping.
According to the angular rate:
Rigid universal joints can be divided into unequal velocity universal joints (such as cross shaft universal joints), quasi-constant velocity universal joints (such as double universal joints, three-pin shaft universal joints) and constant velocity universal joints ( Such as ball cage universal joint, ball fork universal joint). Constant velocity and unequal velocity refer to whether the rotational angular rate of the driven shaft is equal when the driven shaft rotates with the driving shaft. Of course, the average rotational speed of the driving and driven shafts is equal.

Use and maintenance of the drive shaft:
In order to ensure the normal operation of the transmission shaft and prolong its service life, attention should be paid to:
1. It is strictly forbidden for cars to start at high speed.
2. It is strictly forbidden to lift the clutch pedal sharply.
3. Overloading and speeding of vehicles are strictly prohibited.
4. Always check the working state of the drive shaft.
5. Always check the fastening of the drive shaft hanger, whether the support rubber is damaged, whether the connecting part of the drive shaft is loose, and whether the drive shaft is deformed.
6. In order to ensure the dynamic balance of the drive shaft, it is necessary to always pay attention to whether the balance welding piece is desoldered. Supplied with new driveshaft assembly. When loading a new drive shaft, pay attention to the assembly mark of the telescopic sleeve and ensure that the flange fork is in the plane. When disassembling the drive shaft, the assembly marks should be printed on the telescopic sleeve and flange shaft to keep the original assembly relationship unchanged during reassembly.
7. The universal joint cross bearing should be filled with grease frequently. No. 3 lithium-based grease in summer and No. 2 lithium-based grease in winter.
