铁路应用 悬挂部件 气动悬挂弹簧用橡胶隔膜

[中文适用范围]： 本文件规定了悬挂隔膜应达到的特性，以及用于验证的适用检验和测试方法。空气弹簧系统通常由隔膜（本文件的主题）以及附加组件（如紧急弹簧、附加弹簧或两者兼有）和其他组装部件组成。本文件不详细说明空气悬挂或控制系统中的其他组件，如空气储罐、空气管道、高度调节系统、框架、加强板、紧急悬挂系统或弹性支撑（如串联弹簧）等，这些组件会影响隔膜的性能。本文件适用于设计用于安装在铁路车辆及在专用轨道上运行且配备永久导向系统的类似车辆上的空气悬挂隔膜（通过空气充气），无论轨道类型和运行表面如何。这些部件通常由弹性体、纺织织物和金属珠组成。 [外文原描述]： This document specifies the characteristics for suspension diaphragms to achieve, together with applicable inspection and test methods to be carried out for verification. An air spring system usually consists of a diaphragm (subject of this document) and additional components such as either emergency or additional springs, or both, and other assembly parts. This document does not detail the other components of air suspension or control systems such as air reservoirs, air piping, levelling system, frames, stiffeners, emergency suspension systems or elastic supports (such as series springs), etc., which will affect the diaphragm performance. This document applies to suspension diaphragms (inflated with air) designed to be fitted on railway vehicles and similar vehicles running on dedicated tracks with permanent guide systems, whatever the type of rail and the running surface. These parts are typically made with elastomer, textile fabrics and metallic beads.
