Where is the cardan shaft used, and what is the function of the cardan shaft?

The universal joint is the universal joint, the English name universal joint, is a part that maintains the variable angle of view energy transmission, and is used to change the position of the differential line. This is the "joint" component of the universal transmission of the car controller system. The universal joint and differential are called cardan shaft gear transmission.

Where is the cardan shaft used, and what is the function of the cardan shaft?

The structure and function of the universal joint are especially like the joints on the hands and feet of the body. The angle of view is changed due to the energy transmission, integration into the brakes, and the up and down movement of the car when the car is running. However, due to the limitation of the radial specification, the deflection angle is specified. Relatively large. A single universal joint cannot make the instantaneous angular velocity of the output shaft and the shaft-in shaft the same, which is easy to cause vibration, aggravate the destruction of parts, and cause quite loud noise. Therefore, various constant velocity joints are commonly used.

In the front controller on the car, each half shaft uses two constant velocity universal joints. The universal joints close to the speed-regulated drive axle are the inner universal joints of the half shafts, and the universal joints on both sides of the half shafts are close to the axles. The load change during the operation of the trolley or the position difference between the two total distance installations, etc., all cause the angle and distance between the transmission output shaft and the input shaft of the drive axle main reducer to vary greatly, so the universal joint gear of the front controller trolley is placed The box method uses double universal joints to ensure that the instantaneous angular velocity of the output shaft and the shaft input shaft are the same from beginning to end.
