Automobile steering angle mechanism and automobile comprising same

Abstract

The invention provides an automobile steering angle mechanism and an automobile comprising the same, the automobile steering angle mechanism comprises an EPS steering engine, a steering pull rod and ball head assembly, a shock absorber strut, a lower swing arm and a steering knuckle, the steering knuckle is in a line shape, and the upper end of the steering knuckle is connected with an upper ballhead seat assembly of a wheel assembly; the inner side of the knuckle is connected with a lower ball cup assembly of the wheel assembly, the lower end of the knuckle is connected with one end of the lower swing arm, and the other end of the lower swing arm 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 pullrod and ball head assembly is connected with the wheel assembly, and the other end of the steering pull rod and ball head assembly is connected with the EPS steering engine. The EPS steering engine drives the steering pull rod and the ball head assembly, so that the wheel assembly rotates along a virtual main pin formed by an upper ball head point and a lower ball head point of the steering knuckle. Various special mode functions can be achieved, and representativeness includes in-situ turning, transverse movement, oblique translation, ultra-small steering radius steering, cross parking, fixed circle rotation around a certain wheel and the like.

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
