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.
