Problems solved by technology

[0005] In order to overcome the deficiencies in the background technology, the present invention provides a sliding drive shaft with a large swing angle dust cover, which mainly solves the problem that when the current drive shaft slips, the shrinkage of the dust cover is relatively large, and the dust cover is prone to rupture and oil leakage. The problem of shortening the service life of the drive shaft

Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings: as shown in the figure, the sliding drive shaft with a large swing angle dust cover includes an intermediate shaft 1 and a first dust cover 4, and one end of the intermediate shaft is provided with a The movable end universal joint 2 is slidably connected in the axial direction of the shaft, and the other end is provided with a fixed end universal joint 3. The movable end universal joint is movably connected with the intermediate shaft in the axial direction. The knuckle includes a housing 21, and also includes a sliding member 5, which is slidably arranged on the peripheral outer wall of the intermediate shaft along the axial direction of the intermediate shaft, and one end of the first dust cover is connected to the sliding member. The other end is connected to the outer wall of the housing. In this way, when the universal joint at the moving end slides, the sliding me...

Abstract

The invention discloses a slide-type drive shaft for a large-swing-angle dustproof sleeve, and mainly solves the problems that breakage and oil leakage of a dustproof sleeve are easily caused due to ahigh shrinkage amount of a dustproof cover during slide of an existing drive shaft, so that the service life of the drive shaft is shortened. The slide-type drive shaft for the large-swing-angle dustproof sleeve is characterized by further comprising a slide element (5), wherein the slide element is slidably arranged on the circumferential outer wall of a middle shaft in the axial direction of the middle shaft; and one end of a first dustproof cover is connected with the slide element, and the other end of the first dustproof cover is connected with the outer wall of a shell body. According to the slide-type drive shaft for the large-swing-angle dustproof sleeve, the dustproof sleeve uses a slide function while being connected with the middle shaft, so that the stretching amount of the dustproof sleeve is reduced, the breakage problem of the dustproof sleeve is greatly reduced, and the service life of the drive shaft is prolonged.

Description

technical field [0001] The invention belongs to the field of automobile drive shafts, in particular to a sliding type drive shaft with a large swing angle dust cover. Background technique [0002] With the continuous development of the automobile industry, people have higher and higher requirements on the performance of automobiles. In the automobile transmission system, in order to make the output shaft and the input shaft in the same plane rotate at the same speed, the constant velocity universal joint drive shaft assembly with double universal joint transmission is often used. The constant velocity universal joint drive shaft assembly is the power transmission device between the automobile engine and the driving wheels, which is used to provide the traction and speed required by the automobile under various working conditions, and at the same time enable the two to coordinate changes and have sufficient The range of change ensures that the left and right driving wheels o...
