Problems solved by technology
[0006] The technical problems to be solved by the present invention are: firstly, it solves the problem that the motor noise in the traditional EPS is large and cannot realize the function of fully decoupling the steering required by the smart car; secondly, it solves the problem of canceling the steering wheel and The mechanical connection between the steering wheels makes it impossible to complete the failed steering when the system is powered off; third, it solves the problems of high noise and slow response when some brake-by-wire systems use motors as the power source for steering-by-wire; fourth, Solve the problems of leakage, increased failure rate and difficult maintenance when some brake-by-wire systems use liquid or gas as the steering medium

Embodiment Construction
[0047] The technical solution of the present invention will be further explained and described below in the form of specific embodiments in conjunction with the accompanying drawings.
[0048] refer to figure 1 , a full decoupling steer-by-wire system according to the present invention consists of a steering wheel 1, a steering column 2, a decoupled steering simulator 3, a reversing mechanism 4, a left front wheel 5, a right front wheel 6, and a left electromagnetic booster mechanism 7 and the right side electromagnetic booster mechanism 7 form.
[0049] The bottom of the steering wheel 1 is connected to the upper end of the steering column 2. The main function of the steering column 2 is to transmit the torque on the steering wheel 1 to the reversing structure. At the same time, there are various electronic devices such as sensors in the steering column 2 to make it have a steering wheel. Angle adjustment, ignition switch key, steering anti-theft lock, horn circuit, wiper, t...

The invention discloses a full decoupling steering-by-wire system. The full decoupling steering-by-wire system is used for solving the problems that a motor in a traditional EPS is large in noise, andthe function of steering full decoupling needed by an intelligent automobile cannot be achieved; mechanical connection between a steering wheel and a steering wheel is omitted in parts of steering-by-wire systems, and consequently, efficacy-losing steering cannot be completed when the systems are powered off and lose efficacy; when the parts of the steering-by-wire systems adopts motors as steering-by-wire power sources, the noise is large, and the response speed is low; and when the parts of the steering-by-wire systems adopts liquid or gas as a steering medium, leakage occurs, the failure rate is increased, and maintenance is difficult. According to the full decoupling steering-by-wire system, electromagnetic force is adopted to drive a steering rod to move, so that an automobile completes a steering action rapidly and precisely; and the full decoupling steering-by-wire system can achieve full decoupling of a driver and the steering system, has the efficacy-losing protection function, and is free from constraints of the motors, the liquid and the gas, simple in structure and high in integration level.
Description
technical field [0001] The invention relates to a fully decoupled wire steering system. Background technique [0002] With the development of smart cars, traditional EPS (Electronic Power Steering) systems can no longer meet the new requirements of smart cars for steering systems, mainly because traditional EPS is dominated by people, while smart cars hope to Comprehensive consideration of road conditions, the vehicle's own operating status and other information to complete the steering. On the other hand, the traditional EPS system cannot realize the full decoupling of the driver and the steering system, so the steering wheel will move with the active steering at this time, causing the driver to panic. Therefore, it is urgent to develop a fully decoupled steer-by-wire system suitable for smart cars. [0003] Summarizing the patents of various steering manufacturers around the world and scholars at home and abroad, it can be found that the steer-by-wire system, as the late...
