Description

Active suspension device

Technical Field

The utility model belongs to the suspension field, concretely relates to initiative suspension device.

Background

the traditional suspension system is composed of main components such as a guide mechanism, an elastic option piece, a shock absorber and the like, the working principle of the suspension system is mainly to bear and transmit force and moment between a vehicle body and a wheel (axle) and attenuate impact transmitted from the ground, the main principle is to convert excitation of a road surface into elastic potential energy of an elastic element and passively convert the elastic potential energy into heat energy of the shock absorber, in recent years, an air spring is also developed on the market to replace a traditional spring steel spring, the linear sense of the suspension stiffness is better, and some damping passively adjustable suspension systems are also developed. However, these suspension systems are optimized based on the conventional passive suspension, and have certain limitations. The performance of a suspension system directly influences the stability and smoothness of the whole vehicle, and the conventional passive suspension or the optimized semi-active suspension with a certain active function can only play a good role under a certain working condition and cannot give consideration to other working conditions. The main reason is that the rigidity and damping characteristics of the suspension are not adjustable in real time, and the rigidity and damping of the suspension can not be adjusted adaptively according to different use conditions and different working conditions.
