Problems solved by technology

In addition, there are problems of high temperature resistance and rotary expansion of the dust-proof seal cover. One end of the existing dust-proof seal cover is fixed on the intermediate shaft, and the other end is directly fixed outside the ball cage. There is no corresponding buffer space, and the dust-proof seal The cover is injection-molded with a material, which is not conducive to the stability of the vibration wave. After a long time, the dust-proof sealing cover will fall off and break, causing dust and other impurities to enter the ball cage, affecting the normal use of the drive shaft assembly

Abstract

The invention belongs to the technical field of automobile drive accessories and provides a drive shaft assembly vibration reducing mechanism which comprises an inner ball cage assembly, an outer ball cage assembly and a transmission shaft. The transmission shaft is connected with the inner ball cage assembly and the outer ball cage assembly. A dustproof sealing cover is arranged outside the inner ball cage assembly and provided with a primary vibration reducing structure. The transmission shaft is sleeved with a secondary vibration reducing structure. The drive shaft assembly vibration reducing mechanism has the beneficial effects that the two-stage vibration reducing structure is adopted, when the transmission shaft rotates, the dustproof sealing cover will generate vibration waves, the dustproof sealing cover is made of two different materials, the characteristic of the buffering and vibration reducing adjusting part changes, and the adjusting part can adapt to adjusting more powerful vibration. Meanwhile, two stages are adopted at the middle position of the transmission shaft to reduce vibration, the rotating position of the transmission shaft is ensured, thus, the influence caused by vibration of the dustproof sealing cover is reduced, the stability is enhanced, and the situation that the dustproof sealing cover falls off is prevented.

Description

technical field [0001] The invention belongs to the technical field of automobile drive accessories, and relates to a vibration damping mechanism of a drive shaft assembly. Background technique [0002] In order to transmit the power of the car, the drive shaft assembly will be used. At present, the ball cage drive shaft assembly is the most used. It is a very important part of the car. Its power transmission point is always located on the plane of the intersection of the two axes. The ball-cage type drive shaft assembly in the prior art requires a large active angle, because the minimum turning radius of the automobile depends on the maximum wheel deflection angle during steering, so the external drive shaft assembly is required to have as large an active angle as possible. In addition, there are problems of high temperature resistance and rotary expansion of the dust-proof seal cover. One end of the existing dust-proof seal cover is fixed on the intermediate shaft, and the...
