Abstract

一种悬架式列车橡胶空气弹簧,它形似汽车轮胎,胎壁是由外层胶5与内层胶2之间夹有帘布层6组成,在它的上底和下底的中心部位分别开有直径不同的圆形大子口1和小子口7,在大子口1和小子口7的口沿内装有圆环形大钢丝圈3和小钢丝圈8,在两钢丝圈外周均包裹有缓冲胶4和缓冲胶9。本实用新型提供了一种能代替钢板弹簧,噪音小、安全性好、能使列车平稳舒适的悬架式列车橡胶空气弹簧,能广泛用于列车减震。

Description

悬架式列车橡胶空气弹簧
技术领域：
本实用新型涉及一种汽火车、地铁用减震弹簧。
背景技术：
目前，火车、地铁为了减震，过去常用传统的钢板弹簧或绕制弹簧，存在易折断、柔软性差、舒适性差、振动大等缺陷。
发明内容：
本实用新型的目的就是要提供一种能代替钢板弹簧，噪音小、安全性好、能使列车平稳舒适的悬架式列车橡胶空气弹簧。
本实用新型的技术方案是这样实现的：一种悬架式列车橡胶空气弹簧，其特点是：它形似汽车轮胎，胎壁是由外层胶5与内层胶2之间夹有帘布层6组成，在它的上底和下底的中心部位分别开有直径不同的圆形大子口1和小子口7，在大子口1和小子口7的口沿内装有圆环形大钢丝圈3和小钢丝圈8，在两钢丝圈外周均包裹有缓冲胶4和缓冲胶9。
本实用新型只要改变其空气内压，就可以得到不同的承载能力，利用空气弹簧的高度控制阀可使其在一定载荷作用下具有不同的高度以适应多种结构的需求，空气弹簧的刚度与内压成正比，故其刚度是可变的；橡胶空气弹簧具有非线性，可将它的特性曲线(载荷——挠度曲线)设计成理想状态；橡胶空气弹簧与附加空气相连，可使其装置的固有振动频率降低到最小，在任何载荷的作用下，橡胶空气弹簧都保持较低而近乎相等的振动频率，由空气和橡胶构成，磨擦小，不会因为固有的振动而影响隔离高频振动的能力；没有金属间的接触，因此隔离防音效果好；在橡胶空气弹簧与附加空气之间加设一个节流孔，当弹簧上载荷发生振动时，空气流经节流孔发生能量损失，因而起到衰减振动的作用；橡胶空气弹簧的耐疲劳性能优于金属弹簧许多倍，使用寿命长；本实用新型制造容易，安装更换方便、维护保养简单，不需经常检修，无需加油。
附图说明：
图1是本实用新型的外观示意图。
图2是本实用新型的剖视图。
具体实施方案：
从图1、图2可见：本实用新型形似汽车轮胎，轮壁是由外层胶5与内层胶2之间填充帘布层6构成，在上底和下底的中心部位开有圆形大子口1和小子口7，在大子口1和小子口7的口沿内分别装有圆环形大钢丝圈3和小钢丝圈8，在两钢丝圈外周均包裹有缓冲胶4和缓冲胶9。
