Transmission shaft classification

1 Closed universal transmission device

With a single universal joint, the drive shaft is enclosed in a bushing, which is connected with the frame as a ball hinge and fixed with the drive axle.

Its major characteristics are: the transmission shaft housing as thrust tube to transfer the longitudinal force of the car, so that the transmission shaft housing plays the role of the longitudinal swing arm in the guiding mechanism of the suspension system, which is very necessary for the subsequent suspension disassembly spiral spring as an elastic element.

Open universal transmission device

Open universal transmission device is simple in structure and light in weight. It is widely used in modern cars.

3 Main Applications

The application of universal transmission device in automobile mainly includes the following aspects:

(1) Transmission (or transfer) and drive axle: the transmission, clutch and engine of general cars are installed on the frame, the drive axle is connected with the frame through the suspension. In the load change and the car in the uneven road when the jump caused, will make the drive axle input shaft and transmission output shaft between the Angle and distance change.

(2) Cross-country vehicle transmission and transfer: in order to eliminate the frame deformation and manufacturing, assembly errors caused by its axis coaxiality error on the impact of power transmission, must be equipped with universal transmission device.

(3) The half shaft of the automobile steering drive axle is segmented, and the axis of the two half shafts intersects and the Angle of intersection changes when the steering, so the universal joint should be used.

(4) the half shaft of the broken drive axle: the main reducer housing is fixed on the frame, the axle housing swings up and down, the half shaft is segmented, and the universal joint must be used.

(5) The steering shaft of some cars is equipped with universal transmission device, which is conducive to the overall layout of the steering mechanism.
