Gas-liquid interconnected suspension system and damping adjusting method

Abstract

The invention relates to the technical field of automobile suspension systems, and discloses a gas-liquid interconnected suspension system. The system comprises a shock absorber and an air spring, wherein the shock absorber comprises an oil storage barrel and a working cylinder, the side wall of the oil storage barrel is provided with a branch pipeline extending outwards, and a stroke valve is arranged in the branch pipeline; the branch pipeline and the stroke valve form a bypass oil way channel with the opening degree capable of being changed; the bypass oil path channel is communicated to a rod cavity of the working cylinder and a bottom cavity of the oil storage barrel; a through piston cavity is formed in the middle of a spring piston of the air spring; an induction piston is arranged in the piston cavity; a hydraulic oil pipe filled with hydraulic oil is connected between the bottom of the piston cavity and the stroke valve; when the air spring works, the induction piston drives the stroke valve through hydraulic oil to change the opening degree of the bypass oil way channel. According to the suspension system and the damping adjusting method, the air spring and the shock absorber are linked, and the air spring is used as an opening adjusting structure of the shock absorber, so that the damping adjusting performance of the shock absorber is more excellent.

Description

technical field [0001] The present application relates to the technical field of automobile suspension systems, in particular to a gas-liquid interconnected suspension system and a damping adjustment method. Background technique [0002] With the development of the automobile industry, the suspension system, which is the key to vehicle handling and smoothness, is also making continuous progress and breakthroughs. The ideal damping characteristic of the suspension system is to hope that the damping force of the shock absorber of the suspension system can change with the different working conditions and road conditions of the vehicle. [0003] In related technologies, the adjustable damping suspension system developed in the industry is mainly divided into three types. The first is the mechanical gear type adjustable damping shock absorber. The damping force can be changed by the size of the flow aperture; the second is the frequency adaptive shock absorber, which can adjust ...

Problems solved by technology

[0004] However, the adjustment of the damping force of the first type of mechanical gear-type damping adjustable shock absorber depends on the driver’s self-adjustment and selection in advance, and cannot be related to the vehicle’s operating conditions and road conditions in real time; the second type of frequency-adaptive shock absorber, Its limited adjustment range cannot be changed from the time the shock absorber leaves the factory
