Vehicle active suspension system

Abstract

The invention provides a vehicle active suspension system, and belongs to the technical field of vehicles. Thevehicle active suspension system specifically comprises: a mounting support used for mounting the active suspension system on a vehicle body of a vehicle; an upper arm, wherein one end of the upper arm is rotationally mounted on the mounting support through an upper arm shaft, and the other end of the upper arm is connected with a wheel of the vehicle; a first electric cylinder, wherein the two ends of the first electric cylinder are connected with the upper arm and a vehicle body of the vehicle, and the first electric cylinder stretches out and draws back to drive the upper arm to rotate around an upper arm shaft and drive wheels of the vehicle to get away from and get close to the vehicle body in the vertical direction; a driving assembly which is used for driving wheels of the vehicle to rotate; a steering assembly which drives the wheels to steer; a side swing assembly, wherein the upper arm is connected with the mounting support through the side swing assembly, so that the upper arm, the upper arm shaft, the first electric cylinder, the steering assembly and the wheels incline in the vertical direction, and the wheel track of the vehicle is adjusted. By means of the treatment scheme, the functions of wheel type steering, lifting, side swinging and the like of the vehicle are achieved, and the functions of climbing, obstacle crossing, trench crossing, wading, bearing and the like can be easily achieved.

Description

technical field [0001] The present application relates to the field of vehicles, in particular to a vehicle active suspension system. Background technique [0002] The active suspension system has the function of controlling the movement of the body. When the inertia of the car brakes or turns causes the spring to deform, the active suspension system will generate a force that opposes the inertia, reducing the change in the position of the body. Also known as active guidance suspension system, dynamic variable suspension system, etc., by changing the height, shape and damping of the suspension system, it can control the vibration of the vehicle body and the height of the vehicle body, mainly to improve the stability of the car's operation and ride comfort sexual performance. According to the control type, it can be divided into three categories: hydraulic control suspension system, air suspension system and electromagnetic induction suspension system. [0003] The above a...

Problems solved by technology

[0004] For complex road conditions (such as muddying, muddy, ice and snow coverage, falling rocks and mudslides, roadbed erosion and other road blocking conditions) the traffic capacity is not strong

[0005] In addition, the terrain adaptability is not strong. In mountains, hills, alpine mountains and other terrains, natural / artificial obstacles such as steep slopes, dams, trenches, bullet craters, and road pits cannot be passed by themselves.
