Problems solved by technology

[0003] Due to the low working pressure, the traditional air spring takes up a lot of space, and cannot be used on a vehicle with a compact layout and a large axle load. When the working load exceeds the static load, a large radial deformation will occur, which is different from the suspension. Interference with other parts of the frame may easily cause damage to the air spring. At the same time, the rubber airbag lacks effective protection and cannot be used in harsh working environments

Abstract

The invention discloses a membrane-type high-pressure air spring completely wrapped with a sleeve. The membrane-type high-pressure air spring comprises an air bag assembly and the limiting sleeve. The air bag assembly comprises a spring upper end cover, an air bag and a piston which are sequentially connected. The air bag is wrapped with the limiting sleeve. One end of the limiting sleeve is open, and the other end of the limiting sleeve is used for being connected with a vehicle body. The spring upper end cover is located at the end, connected with the vehicle body, of the limiting sleeve and fixedly connected with the limiting sleeve. By the adoption of the membrane-type high-pressure air spring completely wrapped with the sleeve, the damage caused by interference with other portions of a suspension frame by the air bag is avoided, and meanwhile due to the fact that the bearing area is constant, the designability of the stiffness of the air spring is improved, the structure is compact, the bearing capacity is high, and the occupied space is small.

Description

technical field [0001] The invention relates to an air spring, in particular to a membrane-type high-pressure air spring fully covered by a sleeve. Background technique [0002] The air spring is a vehicle suspension elastic element that uses the compressed air inside the rubber airbag as the elastic medium. It has excellent cushioning and vibration isolation performance, and can design complex stiffness characteristics to meet the vehicle suspension for ride comfort and handling stability. requirements. According to the deformation mode of the rubber airbag when it is working, the air spring can be divided into a capsule air spring and a membrane air spring. The membrane air spring mainly obtains elastic deformation by the curling of the rubber airbag. [0003] Due to the low working pressure, the traditional air spring takes up a lot of space, and cannot be used on a vehicle with a compact arrangement and a large axle load. When the working load exceeds the static load, a...
