Follow-up steering mechanism and independent suspension support bridge using same

Abstract

The invention relates to a follow-up steering mechanism, comprising a left steering pull rod, a right steering pull rod and a steering rocker arm, wherein the left end of the left steering pull rod is hinged with a corresponding steering knuckle assembly, the right end of the right steering pull rod is hinged with a corresponding steering knuckle assembly, the steering rocker arm is arranged between the left steering pull rod and the right steering pull rod and can be hinged with a corresponding chassis frame in a left-right swinging manner, and the opposite ends of the left steering pull rod and the right steering pull rod are respectively hinged with the left side and the right side of the steering rocker arm. The follow-up steering mechanism provided by the invention also comprises at least two locking cylinders which are respectively arranged among the left side and the right side of the steering rocker arm and the corresponding chassis frame and are used for applying a loading force to the steering rocker arm to lock the steering rocker arm so as to enable corresponding wheels to move along a straight line. The follow-up steering mechanism provided by the invention has a controllable follow-up steering function.

Description

technical field [0001] The invention relates to the field of vehicles, in particular to a follow-up steering mechanism and an independent suspension support bridge using the steering mechanism. Background technique [0002] With the rapid development of the economy and the improvement of road conditions, the market has higher and higher requirements for automobile transportation efficiency, environmental protection, economy, comfort and other functions. For some large-load vehicles with high passenger capacity and comfort It integrates sex and economy, and has obvious social and economic benefits. In the past, manufacturers generally used rigid bridges as supporting bridges for the third bridge of vehicles, which had disadvantages such as poor comfort and fast tire wear. [0003] In order to solve this problem, Chinese patent CN 201824820 U discloses a "large drop independent suspension front axle assembly" structure. The axle assembly disclosed in this patent document cons...
