摘要： A rail vehicle bogie traction device is provided, which includes a center pin and two traction rubber bag assemblies. Each of the traction rubber bag assemblies includes a traction rubber stack and a rubber bag, the rubber bag is filled with fluid, and a pressure of the rubber bag is settable. The traction rubber stack is connected to the rubber bag. The center pin is fixed on a lower surface of a vehicle body chassis bolster. Each of the two traction rubber bag assemblies has one end connected to the center pin, and another end connected to a cross beam of a rail vehicle frame. The rail vehicle bogie traction device has nonlinear characteristics, which may effectively transmit a longitudinal load, and may also prevent high-frequency vibration of the frame from transmitting to the vehicle chassis bolster and the vehicle body via the traction device.
