Problems solved by technology

Therefore the existing rubber emergency spring cannot meet this requirement
[0003] When the air spring is deflated, there will generally be a hard stop in the vertical direction, and at the same time there will be lateral sliding friction between the cover plate and the wear plate, which cannot meet the stiffness requirements and soft stop requirements in the lateral direction of some high-speed vehicle projects in the deflated state.

Embodiment Construction

[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0022] Such as figure 1 As shown, an embodiment of the emergency air spring assembly of the present invention includes an upper cover plate 1, an air bag 2, an upper end plate 3 and a lower end plate 4, the outer periphery of the upper end plate 3 is connected with the outer periphery of the lower end plate 4 through the air bag 2, and the upper cover A plurality of steel springs 6 are pressed between the plate 1 and the upper end plate 3 along the circumferential direction, and a damper 5 is installed between the upper cover plate 1 and the upper end plate 3 . In this structure, a parallel structure is formed by arranging a plurality of steel springs 6 and dampers 5 in the circumferential direction. The damping force can be realized by adjusting the damper 5, which can prevent the creep phenomenon, the damping can be adjusted, and t...

Abstract

The invention discloses an emergency air spring assembly. The emergency air spring assembly comprises an upper cover plate, air bags, an upper end plate and a lower end plate; the periphery of the upper end plate is connected with the periphery of the lower end plate through the air bags; a plurality of steel springs are arranged between the upper cover plate and the lower end plate in the peripheral direction; and a damper is also mounted between the upper cover plate and the upper end plate. The emergency air spring assembly has the advantages of simple structure, convenience in mounting, low overload vertical stiffness, large vertical deformation, high comfortableness and stability, and capacity of preventing creepage and realizing soft stop.

Description

technical field [0001] The invention mainly relates to shock absorbing technology, in particular to an emergency air spring assembly. Background technique [0002] Air spring components are used in a wide range of applications, such as railway carriages, heavy-duty vehicles, and other applications where cushioning or shock absorption is important. Typically, such spring assemblies include an elastomeric body positioned between a pair of rigid end plates. The elastomer is made of rubber and is compressed by the load applied to the spring assembly. In the prior art, the rubber emergency spring will creep during the service life due to the characteristics of the rubber, and at the same time, due to the nonlinearity of the rubber, the vertical stiffness will increase when the load increases. In some high-speed train projects, the emergency spring is required to have a small change in vertical stiffness, a large dynamic displacement, and no padding is allowed during the service...
