The function of cardan shaft in vehicle

Universal shaft full name "universal coupling", is the basic component of the transmission system, the larger characteristics of thecustom axle shaft with double universal joint - Xinsanming cross shaft coupling is the Angle compensation work capacity, compact structure, high efficiency of the transmission system. When there is an Angle between the axis and the axis, the two connected axes can continue to rotate, and the distance and fitness movement can be transmitted reliably. In the front diesel engine rear drive, the cross shaft gear transmission is installed in the transmission output shaft and the drive car differential input shaft; In the front diesel engine front wheel drive vehicle, the rotating shaft is omitted, and the universal shaft is installed between the front axle assembly drive shaft and the wheels for safe driving and turning.

Working principle of centered cardan half shaft

Cardan axis is a device that transmits driving force between two axes whose relative position changes continuously in the whole process of work. Its function is to connect the output shaft of the gearbox to the input shaft of the automotive differential, which is not on the same parallel line, ensuring that the driving force can be reliably transmitted when the Angle of view and spacing between the two shafts change frequently. The construction and function of the universal axis are much like the joints of human limbs, so that the point of view in the middle of the joint position changes within a certain category. In order to consider the perspective change caused by the driving force driveline, conversion integration and up and down jump during the whole operation of the car, the drive and drive shaft of the front drive car are generally connected with the universal shaft. As everyone knows, because of the radial specification limit, the deflection Angle must be greater. Single cross shaft can not make the output shaft and input shaft instantaneous angular velocity is the same, very easy to cause vibration, aggravating the destruction of parts, resulting in a lot of noise, so it is widely used in constant velocity universal joint shaft.

In the front drive car, each drive shaft is applied 2 constant speed universal shaft, the cross shaft near the drive system bridge is the inner universal shaft, the cross shaft near the shaft is the outer cross shaft. In the rear-drive, the diesel engine, clutch and gearbox are mounted on the window frame as a unit, and the drive is connected to the window frame by a malleable suspension system, which has a certain spacing between them and must be connected. When the car is running, the uneven ground will cause vibration, load change or the difference between the middle parts of the two total processes, etc., and then change the perspective and spacing between the gearbox output shaft and the drive car differential input shaft. Therefore, after driving the drive system of the cross shaft shaft selection of double cross shaft, that is, on both sides of the rotating shaft there are ten cardan shaft, used to pinch the two sides of the rotating shaft, the Angle of intersection is the same, to ensure that the instantaneous angular velocity of the output shaft and the rotating shaft has been the same on the shaft.

There are many connecting methods of universal axis, and different connecting methods have different results when transmitting torsion. If the connection method is not properly selected, it is very easy to transmit torsion, connection key rupture and other problems, resulting in common failures of machine equipment. When the cardan shaft is connected to the shaft, the cardan shaft must be calibrated. If the calibration is not accurate, the characteristics of the cardan shaft will be harmed.
