The application of universal transmission in automobiles mainly includes the following aspects:
①Between transmission (or transfer case) and drive axle: The transmission, clutch and engine of a general automobile are integrated and mounted on the frame, and the drive axle is connected to the frame through the suspension. The load change and the jitter caused by the car driving on uneven roads will cause the angle and distance between the drive axle input shaft and the transmission output shaft to change.
②Between off-road vehicle transmission and transfer case: In order to eliminate the influence of axis coaxiality error on power transmission caused by frame deformation and manufacturing and assembly errors, a universal transmission device must be installed.
③The semi-axle of the steering drive axle of the automobile is segmented, and the two semi-axle axes intersect and the angle of the intersection changes when turning, so a universal joint is used.

④The semi-axle of the disconnected drive axle: the final drive axle is fixed on the frame, the axle housing swings up and down, the semi-axle is segmented, and a universal joint is required.
⑤The steering shaft of some cars is equipped with universal transmission, which is beneficial to the overall arrangement of the steering mechanism.
