A self-pressurization system of a high-pressure and low-pressure cavity closed-loop air suspension system

Abstract

The invention discloses a self-pressurization system for a high-low pressure cavity closed-loop gas circuit air suspension system and relates to the technical field of closed-loop gas circuit air suspension systems. The self-pressurization system comprises a pressurization device, a one-way valve, an inflation electromagnetic valve, an air spring, a deflation electromagnetic valve, a high-pressure tank and a low-pressure tank. The air spring receives gas from the high-pressure tank according to needs to achieve inflation. When deflation is needed, the air spring is deflated to the low-pressure tank through the deflation electromagnetic valve. Meanwhile, the pressure in the low-pressure tank acts on an air pressure touch switch device, a piston rod and a lower lifting lug are disconnected or connected through the device according to the air pressure, the pressurization device pressurizes the gas at multiple levels and then conveys the gas into the high-pressure tank in the extrinsic motivation up-and-down vibration stroke of a suspension, and a cyclic gas circuit is formed. The invention provides the energy storage suspension capable of recycling vehicle vibration energy. The high-pressure gas discharged by the air spring can be effectively recycled and pressurized through the pressurization device to be cyclically used, 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 with a multi-stage self-pressurizing mechanism. Background technique [0002] With the improvement of people's requirements for car ride comfort, air suspension is more and more accepted by everyone because it has the advantages that other suspensions cannot replace in handling and smoothness. The air suspension system can be divided into the air circuit open-loop air suspension system and the air circuit closed-loop air suspension system according to the different ways of air circulation in the process of its body height adjustment. In the air circuit open-loop air suspension system, the high-pressure gas in the air spring is directly compressed by the gas in the atmosphere under the action of the air compressor into high-pressure gas and enters the air spring. When the body height needs to be...
