Automobile steering angle mechanism and automobile including the same

Abstract

The invention provides an automobile steering angle mechanism and an automobile including the same. The automobile steering angle mechanism includes an EPS steering gear, a steering tie rod and a ball joint assembly, a shock absorber strut, a lower swing arm and a steering knuckle, and the steering knuckle is in the shape of a line , the upper end of the steering knuckle is connected to the upper ball seat assembly of the wheel assembly, the inner side of the steering knuckle is connected to the lower ball seat assembly of the wheel assembly, the lower end of the steering knuckle is connected to one end of the lower swing arm, and the lower end of the lower swing arm The other end is connected to the vehicle body; the shock absorber strut is installed on the outer side of the steering knuckle, one end of the steering rod and the ball joint assembly is connected to the wheel assembly, and the other end is connected to the EPS steering gear; the EPS steering gear drives the steering rod and the ball joint The assembly makes the wheel assembly rotate along the virtual kingpin formed by the upper ball point and the lower ball point of the steering knuckle. The present invention can realize a variety of special mode functions, typically including: U-turn in place, lateral movement, oblique translation, ultra-small steering radius steering, cross parking, rotation around a fixed circle of a wheel, etc.

Description

technical field [0001] The invention relates to the field of automobile structures, in particular to an automobile steering angle mechanism and an automobile comprising the same. Background technique [0002] With the rapid development of new energy vehicles, its main technology is to replace the fuel engine with a central motor. The vehicle structure and power transmission mode have not been changed in any way. At the same time, due to the traditional suspension design and steering system, each wheel cannot be turned independently, and the steering radius of the vehicle is large, so it is very difficult to turn and turn around in a narrow area. [0003] Due to the limitations of the transmission shaft structure and tire movement space in traditional cars, the steering angle design is generally between (-38°) and (+32°). The 90-degree steering module based on in-wheel motor technology has been developed and implemented by companies such as Protean and Schaeffler, but their...

Problems solved by technology

When the ambulance enters the community, it is inconvenient to enter and exit due to narrow roads or insufficient turning space, and it often happens that the ambulance cannot arrive at the rescue site in time
