Air spring for railway vehicle 1 Scope This Standard specifies the terms, symbols and coordinate system definition, product property requirements, inspection test method, inspection rules, marking, packaging, storage and transportation of air spring for railway vehicle. This Standard does not describe those components that may influence air spring properties, such as air supply system of air duct, control valve or auxiliary chamber. This Standard is applicable to newly-made air spring for railway passenger vehicles and CRH (China Railway High-speed) vehicles. Air spring for metro vehicles, urban rail vehicles, mono-rail vehicles, magnetic suspension vehicles and other kinds of rail vehicles can use this Standard as reference. 2 Normative references The provisions in following documents become the provisions of this Standard through reference in this Standard. For dated references, the subsequent amendments (excluding corrections) or revisions do not apply to this Standard, however, parties who reach an agreement based on this Standard are encouraged to study if the latest versions of these documents are applicable.

Its structure is shown in Figure 1. Different diaphragm types refer to Annex A. An important component of auxiliary spring which usually consists of metal vulcanized with rubber. 3.1.5.3 Support rim A component performs functions of supporting diaphragm, transmitting load and providing installation space for wearing plate and is between rubber metal spring and airbag, which is usually metal or metal vulcanized with rubber. 3.1.6 Design height Working height in technical specification. It is the installation space of air spring in vertical direction. Properties at height is used as reference to assessing spring performance. This height is also the initial point for calculating vertical deflection and compressing is negative while straining is positive. Note. Technical specification is the technical document provided by customer and approved through specified procedure. 3.1.7 Design state Working state of air spring at load of vehicle weight. 3.1.8 Design pressure Pressure of air spring when it is loaded with empty vehicle at design height. 3.1.9 Effective area Effective active area of pressure for air spring when is inflated. 3.1.10 Auxiliary chamber Separate chamber used to decreasing vertical rigidity of air spring and is connected with diaphragm. 3.1.11 Max outside diameter Periphery diameter of diaphragm in inflated state at maximum vertical load. 3.1.12 Air gap Height difference between bottom surface of top plate of air spring and top surface of auxiliary spring under design pressure. 3.2 Symbols Symbols used in this Standard are listed in Table 1.
