Abstract

The invention provides a vehicle chassis and a vehicle. The vehicle chassis comprises four wheels, a frame, four variable-angle transmission devices, four suspension systems, two differential systems and two steering systems. The frame, the four variable-angle transmission devices, the four suspension systems, the two differential systems and the two steering systems all enable the four wheels to steer towards one side by at least 90 degrees at the same time. Through the layout design of each component device and system in the vehicle chassis, the four wheels can steer towards one side at least 90 degrees at the same time, the situation that each component device and system in the chassis hinder the steering of the wheels is avoided, and the situation that the rotation amplitude of the wheels is limited due to the fact that the wheels are blocked by each component device and system in the chassis is prevented, and the functions of transverse running, four-wheel steering, in-situ rotation and the like of the vehicle are achieved.

Description

technical field [0001] The invention relates to the field of vehicle engineering, in particular to a vehicle chassis and a vehicle. Background technique [0002] With the rapid development of modern society and the improvement of people's living standards, the number of cars is increasing rapidly. However, with the increase of cars, the parking lots and roads in various cities are crowded. At present, most cars are front-wheel steering. , but because the rear wheels cannot be steered, when turning, the turning radius of the car is relatively large, which brings a lot of inconvenience to the majority of drivers when steering and parking on narrow ground. The prior art has the mode that adopts the four-wheel steering of simultaneously controlling automobile to make automobile turn, and some automobile manufacturers once applied four-wheel steering technology in the 1980s. With the development of automobile technology, active safety has been paid more and more attention. Four-...
