Introduction to automobile drive shaft

1. The drive shaft is the shaft in which the driving force can be transmitted in the universal transmission device. This is a high speed, less support plate rotating body, so its rotor dynamic balance is particularly important. Usually the drive shaft in the original factory must use the drive shaft balancing machine to measure the dynamic balance of the rotor, and in the balancing machine to carry out the correction. In the case of a car with an external module in front and rear drive, the transmission rotation is transferred to the shaft of the main reducer. It can be several sections, and the sections between them can be connected by a cross shaft.

2. The automobile drive shaft is composed of a shaft tube, a retractable sleeve and a cross shaft. The retractable sleeve can automatically adjust the change of the interval between the transmission and the drive axle. The cross shaft is to ensure that the transmission output shaft and the drive axle input shaft of the two center line intersection of the change, and the establishment of two axes of the constant angular speed transmission system. Usually cross shaft cross shaft, cross line rolling bearing and convex fork, etc. Steyr series products of heavy duty truck transmission shaft cross shaft selection of roller cross shaft rolling bearings, with each other with short and thick cross shaft, can transmit a large distance. A butterfly spring is arranged under the inner hole of the rolling bearing to clamp the roller. The inner hole of the cross shaft lifts a reinforced polyester gasket with spiral grooves to avoid calcination when driving force is transmitted at large angles or large swivels.
