Booster cavity and high-pressure cavity integrated type closed-loop gas path air suspension system

Abstract

The invention discloses a booster cavity and a high-pressure cavity integrated type closed-loop gas path air suspension system, and relates to the technical field of closed-loop gas path air suspension systems. Two pistons and a piston rod are mounted in a cavity body, one piston is connected with one end of the piston rod, and the other end of the piston rod penetrates through the upper end face of a low-pressure cavity and is connected with an external driving device. A check valve c and a check valve d are mounted on the two pistons respectively. An air spring receives gas from the high-pressure cavity according to needs. When deflation is needed, gas is released to an upper working cavity body and a lower working cavity body of a self-pressurization mechanism through a check valve a and a check valve b. The self-pressurization mechanism fills the gas of the upper working cavity body and the lower working cavity body after accumulation and pressurization into the high-pressure cavity respectively through the check valve c and the check valve d in an extrinsic motivation vertical vibration stroke of a suspension, and a closed-loop gas path is formed. According to the booster cavity and the high-pressure cavity integrated type closed-loop gas path air suspension system, the gas exhausted by the air spring can be retrieved effectively and put into cyclic utilization, and the energy-saving purpose of the air suspension system is achieved.

Description

technical field [0001] The invention relates to the technical field of closed-loop air-circuit air suspension systems, in particular to a closed-loop air-circuit air suspension system integrating a booster chamber and a high-pressure chamber. Background technique [0002] With the improvement of living standards, people not only require automobiles to have good ride comfort and ride comfort, but also put forward higher requirements for energy-saving performance of automobiles due to the increasing scarcity of natural resources. For the automobile air suspension system, according to the different circulation modes of the compressed air in the air spring, the air suspension system can be divided into an open-loop air circuit system and a closed-loop air circuit system. The open-loop air circuit system means that the air in the environment is compressed and pumped into the high-pressure chamber air storage tank, and the air spring is inflated by the high-pressure chamber air st...

Problems solved by technology

The solutions mentioned above all need to start the air pump frequently, which will inevitably consume a certain amount of electric energy, resulting in a waste of energy

Moreover, due to the addition of the gas storage tank of the low-pressure chamber, the complexity of the layout space on the vehicle must be increased.
