    摘要： A primary suspension system is disposed between a wheel journal bearing and a side frame of a railway truck to minimize acceleration forces from being transmitted from a wheel axle unit to a car body. A pair of elastomeric members form a ring clamped around the journal bearing and are bonded to multiple outer plates disposed in different planes. Relatively low spring rates are provided when one set of outer multiple plates are operative with relatively high spring rates being provided when the elastomeric members are compressed and the inner multiple plates become operative.

    摘要翻译： 主悬挂系统设置在车轮轴承轴承和铁路车辆的侧框架之间，以最小化加速力从轮轴单元传递到车体。 一对弹性体构件形成围绕轴颈轴承夹紧的环，并且结合到设置在不同平面中的多个外板。 当弹性体被压缩并且内部多个板变得可操作时，当一组外部多个板操作时提供相对较低的弹簧刚度，提供相对较高的弹簧刚度。
