Air spring for limit buffer, pressure limit impact reduction and static rigidity adjustment with volume

Abstract

A passive air suspension system is commonly used in the prior art; due to the rigidity characteristics and the defects of the air spring of a passive air suspension, the unreasonableness of the matching between the rigidity of standard series of airbags and the parameters of a whole vehicle and the failure of personalized regulation, the vehicle which adopts the passive air suspension quite seriously swings laterally, so that a passenger and a driver are dizzy and uncomfortable, and the promotion and the application of the passive air suspension are badly affected. The invention relates to an air spring for limit buffer, pressure limit impact reduction and static rigidity adjustment with volume, the static rigidity adjustment of the air spring is simple and convenient and feasible, the structure is simple and the cost is low. A buffer air chamber and a buffer throttle plug can effectively improve the dynamic rigidity of the air spring before an airbag is compressed to be in front of a vehicle body limit block, so that the impact of dynamic load on the vehicle body is reduced. The air spring can also automatically reduce the dynamic rigidity of the vehicle when the vehicle runs and hits a bulge on a road surface, so that the impact of the bulge on the road surface on the vehicle body can be reduced, and the smoothness and the comfort of the vehicle are improved.

Description

1. Technical field: [0001] The invention relates to an air spring for a vehicle air suspension. This kind of composite air spring, which is composed of buffer air chamber limit buffer, one-way valve pressure limit and shock reduction, and airbag inner volume adjustment static stiffness, is especially suitable for passenger buses, urban bus buses, and also suitable for freight trucks and rail transit. Vehicles, and passive air suspension systems for special vehicles. 2. Background technology: [0002] In order to improve the ride comfort of the car, improve the comfort of the ride, and reduce the damage of the vehicle to the road and goods, developed countries have widely used air suspension in the suspension system of their transport vehicles. In recent years, my country has also been vigorously promoting and mandating the use of air suspension. In the continuous development of air suspension technology, in order to further improve the stiffness adjustment characteristics ...

AI Technical Summary

Problems solved by technology

At present, the passive air suspension system is commonly used. Due to the defects of the air spring stiffness characteristics of the passive air suspension, and the unreasonable matching between the standard airbag stiffness and the vehicle parameters, and the inability to perform individualized adjustments, resulting in The vehicle with passive air suspension has a serious sideways phenomenon during operation, which often causes dizziness and discomfort to the occupant and driver, seriously affecting the comfort of the occupant and the safe driving of the driver.

This has become the main reason that seriously affects the popularization and application of passive air suspension on passenger cars
