Abstract

A lateral displacement and pivot steering system of an automobile relates to the field of automobile design manufacture and is characterized in that a set of support and driving system composed of hydraulic telescopic cylinders, bearing trundles, pressure bearings, two-way hydraulic motors and a hydraulic telescopic arms is installed on a bearing support of an automobile chassis by utilizing the hydraulic transmission principle. A bearing trundle direction adjusting plate is fixed on a telescopic rod of the hydraulic telescopic cylinder, and two ends of resetting springs are respectively connected with the adjusting plate and the bearing trundle to form a direction adjusting system. The lateral displacement and pivot steering system changes the direction of an oil path and oil flow through different actions of an electromagnetic valve and is capable of enabling the automobile to achieve 90-degree lateral displacement and pivot steering of any angle within 360 degrees.

Description

technical field [0001] The invention belongs to the field of automobile manufacturing, and in particular relates to a system capable of realizing lateral displacement and in-situ steering of the automobile, which is a method for adding new functions of the automobile. Background technique [0002] At present, domestic and foreign automobile production technology has reached a very high level, through the engine, transmission system and different forms of carrying devices to achieve the purpose of people's walking and transportation. But, present automobile also has certain weak point, mainly manifests in: [0003] 1. Cannot achieve 90 degree lateral displacement. [0004] 2. It is difficult or impossible to turn around in narrow road sections and small spaces. Contents of the invention [0005] The present invention aims at overcoming the shortcomings of the prior art and proposes a system with simple structure, convenient operation, and the ability to realize 90-degree ...
