Abstract

The invention discloses a self-pressurized device with a high pressure chamber and a low pressure chamber of a closed air loop air suspension system and relates to closed air channel air suspension systems with self-pressurized mechanisms. The self-pressurized device with the high pressure chamber and the low pressure chamber of the closed air loop air suspension system comprises a solenoid valve (a), a one-way valve (a), a one-way valve (b), a piston, a piston rod, a one-way valve (c), a one-way valve (d), an air pump, a two-position three-way solenoid valve, the high pressure chamber and the low pressure chamber. The inner structure of the low pressure chamber is a cylindrical cavity, two end surfaces of the low pressure chamber are respectively provided with an air inlet and an air outlet, the piston is arranged in the middle of the cavity, and the low pressure chamber is separated into an upper working cavity and a lower working cavity. An air spring receives air from the high pressure chamber for being inflated as needed, the air is discharged into the low pressure chamber through the one-way valves when the air needs to be discharged, and the air discharged from the air spring is pressurized in an up and down vibration stroke of the low pressure chamber which is externally driven by a suspension and then is inflated into the high pressure chamber to form a closed air loop. The self-pressurized device with the high pressure chamber and the low pressure chamber of the closed air loop air suspension system can effectively recover and recycle the air energy discharged from the air spring to achieve the purpose of energy saving of the air suspension system.

Description

technical field [0001] The invention relates to a closed-loop air path air suspension system, in particular to a closed-loop air path air suspension system with a self-pressurizing mechanism. Background technique [0002] With the improvement of people's living standards, on the one hand, cars are required to have better driving comfort, ride comfort and operational stability. On the other hand, due to the increasing scarcity of natural resources, the future development of the automotive industry must also consider energy-saving factors , the maximum energy saving will inevitably become the goal pursued by automobile production in the future. [0003] 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...
