摘要： A railway vehicle and a vibration damping and suspension device thereof are provided according to the present application. The vibration damping and suspension device includes a top cover, an elastic annular member and an outer sleeve. The top cover has an inner positioning pillar and an outer gland, the outer sleeve is fixedly connected to the elastic annular member and the inner positioning pillar is fixedly inserted in the elastic annular member. Both the outer sleeve and the elastic annular member are provided with a gap extending in a radial direction, thus the outer gland can pre-press the elastic annular member against the inner positioning pillar in the radial direction by the outer sleeve. The vibration damping and suspension device has a great universality and can function as a primary suspension device, a secondary suspension device and/or an elastic side bearing. When the vibration damping and suspension device is subjected to a vertical downward outer loading, the elastic annular member generates an elastic deformation to drive the top cover to slide downward with respect to the outer sleeve, thereby realizing the vibration damping function and forming an upward vertical frictional damping at the same time. When the vehicle vibrates, the elastic annular member moves upward to drive the outer sleeve to move upward, to form a downward vertical frictional damping, thereby improving the stability and safety of the vehicle running at a high speed.
摘要翻译：根据本申请提供一种铁路车辆及其减振和悬挂装置。减振悬挂装置包括顶盖，弹性环形件和外套管。顶盖有内定位柱和外压盖，外套固定连接在弹性环形件上，内定位柱固定插入弹性环形件内。外套管和弹性环形部件均设有沿径向延伸的间隙，因此外套管能够通过外套管将弹性环形部件沿径向预压在内定位柱上。该减振悬挂装置具有很好的通用性，可以作为一次悬挂装置，二次悬挂装置和/或弹性侧支承件起作用。当减振悬挂装置受到垂直向下的外载荷时，弹性环形件产生弹性变形，带动顶盖相对于外套筒向下滑动，从而实现减振功能并形成向上的垂直摩擦阻尼的同时。当车辆振动时，弹性环形件向上移动带动外套向上移动，形成向下的垂直摩擦阻尼，从而提高车辆高速行驶的稳定性和安全性。
