In-depth understanding of the car drive shaft is a lot of use drive shaft customers need to understand,

A lot of purchasers maintenance business to understand.

In front engine rear wheel drive or all-wheel drive the car, because the car suspension deformation in the process of movement, the main reducer input shaft drive shaft and transmission (or transfer case) often have relative movement between the output shaft, moreover, to effectively avoid some institutions or device, the inability to achieve linear transfer, must have a device to realize the dynamic normal pass, then a universal joint transmission. The universal joint drive must have the following characteristics:

A. Ensure that the relative position of the two connected shafts changes within the expected range, and can reliably transmit power;

B. Ensure that the two shafts connected can operate evenly. The additional load, vibration and noise caused by the Angle between the universal joints should be within the allowable range;

C. High transmission efficiency, long service life, simple structure, convenient manufacturing, easy maintenance. For the automobile, because the output shaft of a cross shaft universal joint is not equal to the rotation of the input shaft (with a certain Angle), it is necessary to use double universal joint (or more universal joints) transmission, and the two universal joint forks connected with the transmission shaft are arranged in the same plane, and the Angle of the two universal joints is equal. This is very important. The Angle of universal joint should be reduced as far as possible in design.
