A vibration damping device for tunnel traction locomotive includes a first leaf rubber spring assembly disposed between the bogie side plate and the wheelset and for reducing wheel set vibration, a second leaf rubber spring assembly mounted between the bogie and the vehicle body and for reducing vibration of the vehicle body and a cushioning sleeve assembly disposed between the bogie and the traction pin shaft, the first leaf rubber spring assembly includes a first leaf rubber spring and a wedge seat, The wedge-shaped seat is provided with a second inclined surface, and the second inclined surface is provided with a V-shaped groove. The first leaf rubber spring comprises a V-shaped rubber plate, a V-shaped steel plate and an oblique triangular prism. The outer surface of the V-shaped steelplate is slidably matched with the surface of the V-shaped groove, and the oblique triangular prism is fixedly connected with the wedge-shaped bearing seat. The invention can reduce the vibration ofthe wheelset, can provide the flexible connection in the longitudinal and transverse directions of the tunnel traction locomotive, reduces the wear between the wheel and the track, and can prevent thedamage to the bogie and the traction pin shaft caused by the rigid impact.
