[0002] The drive shaft of an automobile refers to the component that transmits the power of the engine to the vehicle tires. It usually consists of a drive shaft, universal joints, and a differential. The drive shaft transmits the power of the engine to the wheels, and the universal joints allow the wheels to maintain steering while transmitting power. The differential balances the rotational speed differences between the wheels to ensure that the two wheels rotate at appropriate speeds during turning. Generally speaking, the drive shaft is crucial for the power transmission and suspension steering of the vehicle.

The outer constant velocity joint is sleeved on one end of the intermediate shaft, and the inner constant velocity joint housing is sleeved on the other end of the intermediate shaft. A noise reduction sleeve is sleeved on the outer constant velocity joint, and a sound insulation sleeve is sleeved on the end of the intermediate shaft close to the outer constant velocity joint. This device can filter and reduce the noise generated by friction between the outer constant velocity joint and the intermediate shaft in multiple directions, improving the performance of the drive shaft.
