What conditions should be met for the design of universal drive shafts?

Cardan drive shafts should be designed to reliably transmit power, and the two connected shafts should run at as constant speed as possible. Additional loads, vibrations, and noise due to the angle of the gimbal should be within the permissible limits. The transmission efficiency is high, and it is necessary to ensure that the relative position of the two connected shafts changes within the expected range. Long service life, simple structure, easy manufacturing, easy maintenance, etc. It is common to use a cross-shaft universal drive shaft between the output shaft of the transmission or transfer case and the input shaft of the drive axle. In the steering drive axle, the constant velocity universal drive shaft is mostly used. When the rear drive axle is independent elastic, a cardan drive shaft is used.
