Problems solved by technology

However, the bogie installation space of some rail vehicle models is too small to install two air springs, and only smaller emergency rubber springs can be installed as an alternative, and emergency rubber springs have poorer vibration damping performance than air springs, resulting in vehicle stability and comfort bad sex

Embodiment Construction

[0023] The specific implementation manners of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Apparently, the embodiments described in the specific implementation are only some of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0024] The invention provides an air spring suitable for a vehicle body in a small space.

[0025] refer to image 3 . The air spring includes an upper cover 5 and a base 6 arranged at intervals, and a support seat 7 located between the upper cover 5 and the base 6 and arranged at intervals with the upper cover 5 and the base 6 . The air spring is a rotating body. In this embodiment, the upper cover 5, the base 6 and the support seat 7 are all circ...

Abstract

The invention provides an air spring. The air spring comprises an upper cover and a base which are alternately arranged, a supporting seat which is positioned between the upper cover and the base and is alternately arranged between the upper cover and the base, and an elastic capsule body which is arranged between the upper cover and the supporting seat. The air spring is characterized in that along the radial direction of the upper cover and the base, the elastic capsule body comprises an elastic outer capsule and an elastic inner capsule which are alternately arranged; openings are formed in peripheral sides of the elastic inner and outer capsules and are respectively connected with the upper cover and the supporting seat to form a closed space in an enclosing way; through mounting holes are formed in the upper cover and the base and are arranged in a straight line for mounting the air spring. A traditional air spring is only provided with a capsule body similar to the elastic outer capsule of the air spring, and the structure of the elastic inner capsule is additionally arranged based on the elastic outer capsule, so that both requirement of a vehicle with limited space for mounting space and vibration damping performance can be solved.

Description

technical field [0001] The invention belongs to the technical field of vehicle vibration reduction, and relates to a vibration reduction component, in particular to an air spring. Background technique [0002] Air spring is a kind of rubber shock-absorbing element filled with compressed air and using the compressibility of air to realize elastic buffering function. It is the main secondary suspension component of rail vehicles. Relative displacement, while providing bearing capacity and stiffness in all directions. [0003] At present, the main structural forms of air springs are shown in figure 1 , generally by the upper cover 101, rubber air bag 102 and emergency rubber spring 103 and other components. The schematic diagram of the assembly structure of the air spring 1 and the car body 2 is as follows: figure 2 As shown, when the air spring 1 is assembled between the vehicle body 2 and the bogie 3, the upper intake column 104 and the lower intake column 105 of the air ...
