1 Scope

This document specifies the symbols, coordinate system definitions, application conditions, technical requirements, and testing methods for rubber elastic elements in locomotive and rolling stock suspension systems.

Laws, inspection rules, and marking, packaging, transportation and storage.

This document applies to the suspension systems and equipment of railway locomotives, passenger cars, freight cars, EMUs, and various self-propelled special equipment.

Rubber elastic elements used in installation systems, connections, and limiting parts to provide vibration damping, cushioning, flexible connections, and limiting functions. Urban rail vehicles.

Refer to the usage guidelines for vehicle-mounted rubber elastic elements.

This document does not apply to locomotive and rolling stock windshields, air springs, sealing rubber products, coupler buffer rubber parts, hoses, and conveyor belts.

Note. Common types of rubber elastic elements are listed in Appendix C.
