Mechanism enabling wheels to steer in same direction and in inverse direction

Abstract

The invention discloses a mechanism enabling wheels to steer in the same direction and in an inverse direction. The mechanism is provided with a mechanical steering unit, an electronic control unit and an executing unit, wherein the electronic control unit comprises an electronic control unit (ECU); the mechanical steering unit comprises a steering transmission shaft, a gear rack transmission mechanism and a sliding rod guiding mechanism; the steering transmission shaft is connected with a helical gear in the gear rack transmission mechanism; one end of the gear rack transmission mechanism is connected with the sliding rod guiding mechanism; the executing unit comprises a step motor in the sliding rod guiding mechanism; and the step motor is connected with the ECU, and is also connected with the sliding rod guiding mechanism. According to the mechanism disclosed by the invention, a worm wheel and worm mechanism is adopted, so that transmission is smooth and noises are low; the mechanism mainly adopts a mechanical transmission mechanism, so that the bearable working pressure is large and the reliability is high; wheels on two sides can steer in the same direction or in an inverse direction, so that the translation and 360-degree steering of an automobile can be realized, and the maneuvering performance of the automobile is improved; and the steering mechanism is convenient to arrange and lightweighting is facilitated.

Description

technical field [0001] The invention relates to a steering mechanism system for automobiles, in particular to a wheel co-directional and reverse steering mechanism. Background technique [0002] The steering system of a car is a key component of a car, not only affecting the driving comfort, but also an important part of the convenience of driving and manipulation. The currently used mechanism that can enable the wheels on both sides to realize the same direction and reverse steering is to configure steering motors for each wheel, and individually manipulate the steering of each wheel through an electronically controlled motor system. When the wheels on both sides turn in the same direction, it is the same direction steering, and when the wheels on both sides turn in the opposite direction, it is the reverse direction. [0003] Most of the wheel co-direction and reverse steering mechanism systems used on the market are purely electronically controlled motor steering systems...

AI Technical Summary

Problems solved by technology

[0003] Most of the wheel co-direction and reverse steering mechanism systems used on the market are purely electronically controlled motor steering systems. This system is convenient to arrange, but due to the frequent steering operations, there are vibrations and high working pressure during the movement of the car. The reliability of the control system is low, making it difficult for the electronically controlled motor steering system to meet the requirements of frequent daily use of modern vehicles

[0004] The traditional steering mechanism system is inflexible in steering and has a large steering radius. It can only realize the steering of the wheels on both sides in the same direction, but cannot meet people's increasingly higher requirements for vehicle driving convenience. With the development of automatic driving technology, there is an urgent need for a Efficient and convenient steering mechanism system to realize the convenience of vehicle steering
