Information

The structure of automobile transmission shaft is composed of shaft tube, telescopic sleeve and universal joint. The combination of universal joint and transmission shaft is called universal joint transmission device.

Shaft tube

1. In order to reduce the friction and wear when the shaft moves, it is used for the same purpose as the bearing. The cost is cheap, but the friction resistance is large, so it will only be applicable to some parts;

2. The shaft sleeve is mostly placed in the shaft and supporting structure, and is very close to the supporting structure. Only the shaft can rotate on the shaft sleeve;

3. When assembling the shaft and shaft sleeve, lubricant will be added between them to reduce the friction generated during rotation.

Telescopic sleeve

1. The telescopic sleeve can automatically adjust the change of the distance between the transmission and the drive axle;

2. The new transmission shaft welds the spline sleeve and the transmission shaft tube into a whole, and makes the spline shaft and the flange fork into a whole;

3. Change the rectangular tooth spline into involute short tooth spline with large pressure angle, which not only increases the strength, but also facilitates extrusion forming, and meets the needs of high torque working conditions;

4. The tooth surfaces of the telescopic sleeve and spline shaft are coated with a layer of nylon material as a whole, which increases the wear resistance and lubricity, reduces the damage of impact load to the transmission shaft and improves the cushioning capacity.

a universal coupling

1. The universal joint ensures the change of the included angle between the output shaft of the transmission and the input shaft of the drive axle, and realizes the constant angular speed transmission of the two shafts;

2. Universal joint, i.e. universal joint, is a mechanical part to realize variable angle power transmission. It is used to change the position of transmission axis direction. It is the "joint" component of universal transmission device of automobile drive system;

3. The universal joint is a component that changes the direction of force transmission. Its function is a bit like the limb joints of the human body. It allows the included angle between the connected parts to change within a certain range. Its wear and deformation will produce abnormal noise and vibration if it is light, and the power transmission device will be interrupted if it is heavy;

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 transmission shaft, which is used to make the included angles at both ends of the transmission shaft equal, so as to ensure that the instantaneous angular velocity of the output shaft and the input shaft is always equal;

The transmission shaft is an important component in the automobile transmission system to transmit power. Its function is to transmit the power of the engine to the wheels together with the gearbox and drive axle to generate driving force for the automobile.

Four symptoms of automobile drive shaft failure

The power generated by the engine is called torque. The function of the drive shaft is to transmit this torque power to the wheels of the vehicle. Most economy cars are front wheel drive

What is the material of automobile transmission shaft

Automobile transmission shaft is one of the parts, which can be said to be a device for transmitting power. The function of the transmission shaft is to transmit the power of the gearbox to the driving wheels to make the vehicle move forward or backward normally.

Common troubleshooting of transmission shaft

The damage, wear, deformation and loss of dynamic balance of transmission shaft parts will cause abnormal noise and vibration during driving, and in serious cases, it will lead to the damage of relevant parts. When the car is driving, it makes a "geden" sound when starting or accelerating rapidly, and obviously shows the feeling of loose parts.
