Steering middle shaft protection cover assembly

Abstract

The invention discloses a steering middle shaft protection cover assembly which comprises a sealed connecting plate, a connecting cylinder, a pressing plate, a support shell and a sealing ring. A plurality of installation holes are distributed in the edge part of a first surface of the sealed connecting plate; a second surface opposite to the first surface is connected with a vehicle body; the sealed connecting plate is made of a soft material; the connecting cylinder is fixed to the first surface of the sealed connecting plate and is in seamless connection with the first surface of the sealedconnecting plate; an inner hole of the connecting cylinder extends to the second surface; the connecting cylinder is made of an elastic material; the pressing plate sleeves on the periphery of the connecting cylinder and is detachably connected with the first surface of the sealed connecting plate; a plurality of second installation holes in one-to-one correspondence with the first installation holes are formed in the pressing plate; an outer wall of the support shell is connected with an inner hole of the connecting cylinder in a sleeving way; a third installation hole for sleeving a steering middle shaft, and a first installation cavity and a second installation cavity for installing the sealing ring are arranged in the support shell; and the sealing ring is connected with an outer wallof the steering middle shaft in a sleeving way. According to the steering middle shaft protection cover assembly provided by the invention, a supporting function and a sealing performance of the protection cover can be improved.

Description

technical field [0001] The invention relates to the field of automobile steering systems, in particular to a steering intermediate shaft shield assembly. Background technique [0002] The steering system of an automobile is to help the vehicle realize the steering function. The steering system is generally composed of steering wheel, steering column, steering gear and other components. The steering gear is generally fixed on the chassis outside the cockpit, while the steering wheel, steering column and other components are inside the cabin. The steering transmission force from the steering wheel to the steering gear must pass through the cab or the cabin, which requires openings on the floor of the cab or the cabin, and in order to maintain a good seal in the cab, the sealing effect of the steering column guard And the dustproof effect is particularly important. [0003] The existing steering guard structure such as figure 1 As shown, the intermediate shaft guard 30 is fi...

AI Technical Summary

Problems solved by technology

When the eccentricity of the steering intermediate shaft 40 is large, the unilateral force on the inner support ring 33 is relatively large, and abnormal noises are likely to occur. At the same time, both the inner and outer support rings are metal bodies. , it is easy to cause the rubber to pull, which is prone to tearing problems
