Abstract

The embodiment of the invention discloses a torsional vibration absorber, relates to the field of power transmission systems of automobiles, solves the technical problem that torsional vibration of a transmission shaft can not be absorbed in a process of implementing power transmission in the prior art, and aims to improve the running smoothness of the whole automobile and reduce the noise. The torsional vibration absorber comprises a first transmission element connected with the driving end of the transmission shaft, a second transmission element which is connected with the driven end of the transmission shaft and sleeved on the first transmission element and a vibration absorption element which is arranged between the first transmission element and the second transmission element and used for transmitting torque, wherein the vibration absorption element comprises a rigid base body and a rubber ring; the rigid base body is in interference fit with an inner hole of the first transmission element; and the rubber ring is pressed on the outer surface of the rigid base body and is in interference fit with an inner hole of the second transmission element. The torsional vibration absorber is used for transmission shafts of automobiles.

Description

technical field [0001] The invention relates to a power transmission system of an automobile, in particular to a torsional shock absorber. Background technique [0002] For the car transmission system, when the engine is front-mounted and the rear wheels are driven, the power of the engine needs to be transmitted to the rear of the vehicle through a long transmission shaft, and then transmitted to the driving wheels. In order to achieve this purpose, the current vehicle transmission shaft generally includes a hollow cylindrical drive shaft tube and front and rear sliding forks. The front and rear ends of the drive shaft tube are welded with front and rear welding forks, and the front and rear welding forks pass through Front and rear universal joints connect the drive shaft tubes with the front and rear sliding forks. The front and rear universal joints provide a rotational drive connection from the output shaft of the engine / transmission assembly, via the drive shaft tube,...
