Abstract

An automobile transmission shaft torsional shock absorber, which is used to solve the problems of the existing torsional shock absorber that the elastic connectors are easily damaged and the overall life is short, including an inner skeleton, an inertia ring, an outer ring, a centering and limiting element, and a rubber block , the inner frame is connected with the flange of the transmission shaft through a bolt assembly, rubber blocks are uniformly distributed on the outer wall of the inner frame, one side of the rubber block is vulcanized and fixed on the outer wall of the inner frame, and the other side is vulcanized and fixed on the inner wall of the outer ring , the outer ring is fitted on the outside of the inner frame, and inertia rings are press-fitted on the inner walls at both ends of the outer ring, and the centering and limiting elements are evenly distributed in the cavity between the outer ring and the inner frame. The invention has the characteristics of few parts, simple structure and reliable performance, can not only improve the driving comfort of the vehicle, but also prolong the service life of the torsion damper of the transmission shaft of the vehicle.

Description

technical field [0001] The invention relates to a shock absorber, in particular to a torsional shock absorber for an automobile transmission shaft, belonging to the technical field of automobiles. Background technique [0002] The drive shaft is one of the important components in the automobile drive train. It cooperates with the universal joint to form a universal transmission device. Transfer power to the drive wheels. Because the drive shaft will vibrate during the driving of the vehicle, which will adversely affect the driving comfort of the vehicle. Therefore, automobile designers have installed various vibration damping devices on the drive shaft. The torsional vibration effect of the small propeller shaft is remarkable, and it has been widely used in vehicles. [0003] The existing drive shaft torsional vibration damper is generally composed of an inner ring, an outer ring, and an elastic connecting piece (mostly rubber) between the two. The inner ring is rigidly co...
