Air storage device for air suspension system

Abstract

The invention provides an air storage device for an air suspension system. The air storage device comprises a deflation valve, an inflation valve and a plurality of air storage units, wherein each airstorage unit is composed of M air storage containers, one air storage container serves as a main container, and the remaining air storage containers are classified into N levels; each air storage container is provided with an input end and an output end, and in the same air storage unit, the output ends of the ith-level air storage containers are communicated with the input end of one (i-1)th-level air storage container through a connecting pipe; and the output ends of the jth-level air storage containers are communicated with the input end of one (j+1)th-level air storage container through aconnecting pipe. According to the air storage device, branching of the inflation and deflation pipelines of the air storage containers of different levels is achieved, and inflation and deflation onthe different branches do not interfere with each other due to the arrangement of the one-way valves, so that the influence of faults of the single air storage container on the whole air storage device is reduced as much as possible, and the safety and reliability of the air storage device are improved.

Description

technical field [0001] The invention relates to the technical field of automobile air suspension, in particular to an air storage device for an air suspension system. Background technique [0002] Air suspension systems are used in the chassis of an increasing number of vehicles, including passenger and commercial vehicles, as well as other special-purpose vehicles. Compared with the traditional suspension, the structure of the air suspension is more complicated, and the number of components has increased, especially for the four-point air suspension, an air tank needs to be added. The main function of the air storage tank is to quickly and timely fill the air spring with high-pressure gas, so that the air spring can reach the required height and stiffness in a short time. [0003] Since the volume of the gas storage tank is generally relatively large, adding a gas storage tank is a great challenge to the layout of the vehicle. In order to design a gas storage tank that me...

Problems solved by technology

In order to design a gas storage tank that meets the volume requirements in a harsh or limited space, the gas storage tank is usually designed as a special shape or the layout space of other parts is sacrificed, and the difficulty of processing and layout of the gas storage tank is increased.
