Abstract

The invention relates to an automobile steering system capable of achieving an ideal Ackerman angle relation. The automobile steering system comprises a steering gear shell body fixed to an automobile auxiliary frame, a rack set slidably installed in the steering gear shell body, two wheels, a gear rack transmission mechanism, a steering column and a steering wheel. The rack set comprises a rack A segment and a rack B segment which are connected through a rack equivalent length adjusting mechanism. The rack A segment is slidably installed in the steering gear shell body. The rack B segment is slidably installed in a rack support fixedly connected to the automobile auxiliary frame. The two wheels are further arranged at the ends of the rack A segment and the rack B segment correspondingly. Compared with the prior art, the invention provides the structure of the steering system capable of achieving the ideal Ackerman angle relation under the premise that mechanical connection of the left wheel and the right wheel in the steering system is not cut off, and the performance of the steering system is improved meanwhile the safety is ensured.

Description

technical field [0001] The invention relates to an automobile steering system, in particular to an automobile steering system capable of realizing the ideal Ackermann angle relationship. Background technique [0002] The traditional car steering system basically relies on the rotation of the front wheels. In order to ensure that all the wheels rotate around the same instantaneous steering center, the turning angles of the inner and outer wheels are not equal when turning. The two must satisfy a certain functional relationship, which is what we call Ackerman corner relation. However, the current steering system is limited by the geometrical constraints of the mechanical structure, and can only realize that the inner and outer wheel rotation angles approximately satisfy the Ackermann rotation angle relationship. Therefore, during the steering process of the vehicle, there will be a certain degree of relative sliding between the wheel and the road surface, which will cause tir...
