Novel transition arm structure

Abstract

The invention relates to a novel transition arm structure which comprises a transition arm and bushing assembly, a transition arm bracket and shaft assembly, adjusting gaskets, a steering middle arm shaft retaining ring and locking nuts. A transition arm bracket and a shaft are welded together to form the transition arm bracket and shaft assembly; the transition arm and bushing assembly and the transition arm bracket and shaft assembly are assembled through the match of a bushing and the shaft and fixed through the steering middle arm shaft retaining ring and the locking nuts; the gap between the end surfaces of the transition arm and bushing assembly and the transition arm bracket and shaft assembly is adjusted by using the adjusting gaskets; in addition, two sides of the transition arm and bushing assembly are provided with an oil seal and a dustproof cover respectively; the adjusting gaskets can not cause abrasion to the components; if a transition arm is abraded, the matching gap can be reset by dismounting part of the adjusting gaskets; and moreover, the matching surfaces are fully sealed so that good lubricating environment can be ensured. Due to the characteristics, the abrasion of the transition arm can be greatly reduced, the service life can be prolonged, and the maintenance cost can be lowered.

Description

technical field [0001] The invention relates to a novel transition arm structure, which belongs to the technical field of air steering systems of medium and heavy trucks. Background technique [0002] The traditional transition arm structure consists of the following structures: transition arm and shaft assembly, transition arm bracket and bushing assembly, gasket, steering intermediate arm bracket cover, and lock nut. [0003] The transition arm and the transition arm shaft are welded to form the transition arm and shaft assembly. The transition arm and shaft assembly, the transition arm bracket and the bushing assembly are assembled through the cooperation of the shaft and the bushing, and are fixed by the bracket cover and the lock nut. There are gaskets between the transition arm bracket and bushing assembly, the transition arm and shaft assembly and the end face of the steering intermediate arm bracket cover, and the axial clearance is adjusted by the gasket.

AI Technical Summary

Problems solved by technology

[0005] The gasket is involved in wear, and the transition arm is easy to loose after the gasket is worn, so the gasket needs to be replaced regularly, and the maintenance cost is high

The mating surface is connected to the surrounding environment, and harmful impurities such as dust and muddy water can easily enter the mating surface, and the grease is easy to leak and lose, which will aggravate wear and affect the appearance
