The automobile drive shaft is a key component in the universal transmission device, which can transmit power. As a high-speed, less-supported rotating body, the dynamic balance of the drive shaft is crucial. Before leaving the factory, the drive shaft is usually adjusted on a balancing machine to ensure its dynamic balance. For front-engine rear-wheel drive cars, the drive shaft transmits the rotation of the transmission to the final reducer. This process may involve multiple sections, and the sections are connected by universal joints. The composition of the drive shaft includes universal joints, drive shaft tubes and other components. Its core function is to work with the gearbox and drive axle to transmit the power of the engine to the wheels, so that the car can generate driving force.
The drive shaft is a rotating body with high speed and few supports, so its dynamic balance is very important. Generally, the drive shaft is tested for dynamic balance before leaving the factory and adjusted on a balancing machine. For cars with front engines and rear wheels, the rotation of the transmission is transmitted to the shaft of the main reducer. It can be several parts, which can be connected by universal joints.
The drive shaft consists of a shaft tube, a telescopic sleeve and a universal joint. The drive shaft is used to connect or assemble various accessories. The accessories of movable or rotating round objects are generally made of light alloy steel pipes with good torsion resistance. For cars with front engines and rear wheels, the rotation of the transmission is transmitted to the shaft of the main reducer, which can be connected by several universal joints. It is a rotating body with high speed and few supports, so its dynamic balance is very important. Generally, the drive shaft is tested for dynamic balance before leaving the factory and adjusted on a balancing machine.
The drive shaft consists of a shaft tube, a telescopic sleeve and a universal joint. The telescopic sleeve can automatically adjust the change in the distance between the transmission and the drive axle. The universal joint ensures the change of the angle between the transmission output shaft and the drive axle input shaft, realizing constant angular velocity transmission of the two shafts.
In addition, the design of the automobile drive shaft takes into account various dynamic conditions that the vehicle may encounter during operation, such as the beating caused by uneven road surface, load changes, and the difference in the installation position of the two assemblies, which may affect the angle and distance between the transmission output shaft and the input shaft of the drive axle final reducer. In order to cope with these changes, the drive shaft adopts universal joints and other designs to ensure that power can be transmitted reliably when the relative position changes, while ensuring that the two shafts run evenly, with high transmission efficiency and long service life.
