    • A rail vehicle bogie draw-gear comprising a center pin (20) and two rubber draw bag assemblies (30); each of the rubber draw bag assemblies (30) comprises rubber pads (32) and a rubber bag (31), said rubber bag (31) being filled with a fluid and set to a desired pressure; the rubber pads (32) and the rubber bag (31) are interconnected; the center pin (20) is fixed on the underside of a vehicle chassis bolster (10); one end of each of the two rubber draw bag assemblies (30) is connected to the center pin (20), and the other end is connected to the cross beams of the framework (40) of a rail vehicle. The draw-gear of the present invention has nonlinear rigidity properties. While effectively transmitting longitudinal load, the invention can also prevent high-frequency vibration of the framework from being transmitted through the draw-gear to the vehicle chassis bolster and to the vehicle body, thereby improving riding comfort.
    • 一种轨道车辆转向架牵引装置,包括中心销(20)和两个橡胶牵引袋组件(30); 每个橡胶拉伸袋组件(30)包括橡胶垫(32)和橡胶袋(31),所述橡胶袋(31)填充有流体并设定为所需压力; 橡胶垫(32)和橡胶袋(31)相互连接; 中心销(20)固定在车辆底盘支架(10)的下侧; 两个橡胶牵引袋组件(30)中的每一个的一端连接到中心销(20),另一端连接到轨道车辆的框架(40)的横梁。 本发明的牵引装置具有非线性刚度特性。 在有效地传递纵向载荷的同时,本发明还可以防止框架的高频振动通过牵引齿轮传递到车辆底盘支架和车体,从而提高乘坐舒适性。
