Automobile steering system

Abstract

The automobile steering system includes the first vertical arm with middle part connected to the output shaft of the steering gear, the second vertical arm with the middle part connected to the output shaft of the assisting servo device, the first straight axle pull rod hinged to lower end of the first vertical arm, a linking pull rod with end hinged separately to the upper end of the first vertical arm and the upper end of the second vertical arm, and the second straight axle pull rod hinged to lower end of the second vertical arm, and has no transition arm similar to that in available steering system. The automobile steering system has relatively great regulating space and range, and can cooperate the first front axle and the second front axle in the turning angles and avoid the abnormal and early wear of the tyre in the second front axle.

Description

technical field [0001] The invention relates to a double front axle automobile steering system. Background technique [0002] The steering settings of the existing dual front axle automobiles are that the first front axle is active, the second front axle is follow-up, and the realization of the wheel rotation angle of the second front axle is realized by a set of pull rod systems. , the existing double front axle car adopts the connecting hole of the first drop arm and the output shaft of the steering gear on the top, the connecting holes of the two tie rods are set at the same end of the first drop arm downward, and the first drop arm is located between the frame and the steering gear Between, the second vertical arm is connected with the output shaft of the booster servo, and the situation of the second vertical arm is similar to that of the first vertical arm. [0003] In addition, in the steering system of double front axle automobiles on the existing market, in order t...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the problems of difficult coordination, difficult arrangement and abnormal wear of tires in the existing double front axle steering system, the present invention provides a steering system for automobiles

[0006] Beneficial effects: the steering system, due to the large adjustment space and range, can coordinate the corner relationship between the second front axle and the first front axle, make the turning centers of the steering wheels intersect at one point as much as possible, and make the wheels of the second front axle turn Do pure rolling as much as possible to solve the problem of abnormal tires and early wear on the second front axle; improve the movement coordination of the steering system, solve the interference between the systems, and satisfy the vehicle's handling stability; facilitate the layout of the system and the suspension system Arrangement, easy assembly, easy maintenance; reduce weight and reduce vehicle manufacturing cost
