摘要： The present invention provides a two-stage stiffness type elastomer combined device, including at least one small-stiffness elastic element and a large-stiffness elastic element, wherein the small-stiffness elastic element is arranged in an elastomer pre-compression device and is serially arranged with the large-stiffness elastic element under the action of a pre-compression load F1. The device has combined stiffness being hard at first and then becoming soft and is used as an elastic axle box suspension device of a railway vehicle, effectively solving the contradiction that a linear snaking critical operation speed of the vehicle and curve passing performance of the vehicle cannot be compromised. The device can also be applied to a variety of occasions requiring combined stiffness being soft at first and then becoming hard of an elastomer damping device between related members of the railway vehicle, so as to buffer the wheel rail impact of the vehicle, improve the dynamic performance of the vehicle and guarantee the operation safety of the vehicle to perfect the operation quality of the railway vehicle.
摘要翻译：本发明提供一种两级刚性型弹性体组合装置，其包括至少一个小刚度弹性元件和大刚度弹性元件，其中所述小刚度弹性元件布置在弹性体预压缩装置中并且是串联的在预压缩载荷F1的作用下布置有大刚度弹性元件。该装置首先硬组合刚度然后变软，并被用作铁路车辆的弹性轴箱悬挂装置，有效地解决了车辆线性蛇形临界操作速度和车辆曲线通过性能不能相矛盾的矛盾被妥协。该装置还可以应用于首先需要组合刚度柔软并随后变得难以在铁路车辆的相关部件之间的弹性体阻尼装置的各种场合，以便缓冲车辆的车轮轨道冲击，从而改善动态车辆性能，保证车辆的运行安全，完善铁路车辆的运行质量。
