The invention discloses a mechanical backup device for a steering system of a wire controlled hydraulic automobile, which belongs to the field of vehicle steering system. The steering rack of the invention is tilted on the side of the rotating gear and meshes with the rotating gear. The steering hydraulic cylinder is tilted on both sides of the lower and lower bracket of the lower end of the rack, and the upper and lower ends of the steering hydraulic cylinder are connected to the control of the one end of the solenoid valve, and the upper oil pipe is connected respectively to the control of the one end of the solenoid valve, and the failure controller and the two control are controlled. The control wire harness is respectively connected and arranged between the electromagnetic valves. The composite hydraulic cylinder is set horizontally to control the lower side of the solenoid valve. The two inner oil ports of the inner hydraulic cylinder and one end of the control solenoid valve are respectively connected and arranged with the lower oil pipe. The design of the invention is reasonable, and the mechanical connection between the steering wheel and the wheel can be quickly established when the vehicle is actively turned to the execution part, realizing the direct control of the steering wheel on the two wheels in the front part of the body to ensure the safety of the vehicle driving.

技术介绍
随着人们生活水平的逐渐提高,汽车在人们的生活工作也越来越多的被使用,汽车种类较多,按照用途进行分类,汽车包括轿车、客车和货车,汽车在很多行业中都被广泛的进行应用,汽车已经成为现代人日常生活中必不可少的交通工具。整辆汽车设计过程中,理想状态下要求转向内外轮转角符合阿克曼几何学,即各车轮必须围绕一个共同的中心点进行转弯,以使轮胎不发生侧向滑移和保证整车的转弯灵活性。但实际状态下,由于转向内外轮由一根杆连接(循环球转向系统是由横拉杆连接,齿轮齿条转向系统是由齿轮齿条转向器进行连接,此处将齿轮齿条转向器当做一根杆看待),转向时通过这根杆的轴向平移来实现车轮转向,从而不能保证内外转向轮围绕一个共同的中心点进行转弯,不能完全符合阿克曼几何学,从而影响轮胎寿命、整车的转弯灵活性等。现有的汽车行业领先的DAS线控主动转向:三组ECU电脑根据方向盘的转动来将信号传递给三组电机,再由其中两组电机来控制车轮的转动角度和速度,一组电机来模拟路面的回馈力,另外还留 ...
