The invention provides a railway vehicle traction device suitable for a meter-gauge short-wheelbase cardan shaft transmission system, and relates to the technical field of urban rail transit vehicles, the railway vehicle traction device comprises an upper traction body and a lower traction body, the upper traction body and a center pin are of an integrated casting structure and are fixed on the lower plane of a vehicle body chassis, a center spherical hinge is arranged in the lower traction body, and the center spherical hinge is fixed on the lower plane of the vehicle body chassis. The upper plane of the central spherical hinge is fixed on the upper plane of the lower traction body through the upper cover, the lower part of the upper traction body is in interference fit with the central spherical hinge, two cantilevers of the lower traction body are respectively connected with one end of a traction pull rod, and the other end of the traction pull rod is connected with a framework cross beam; a transverse shock absorber seat used for being connected with a transverse oil pressure shock absorber is arranged on the outer side of the cantilever of the lower traction body. Under the condition that the height of a vehicle traction point does not affect axle load transfer, the traction structure can avoid the cardan shaft, and the space limiting requirement and the mechanical performance requirement of the meter gauge short wheelbase cardan shaft transmission system bogie are met.

    本发明提供一种适用于米轨短轴距万向轴传动系统的轨道车辆牵引装置,涉及城市轨道交通车辆技术领域,包括上牵引体和下牵引体,所述上牵引体与中心销为一体铸造结构,固定于车体底架下平面上,所述下牵引体内部设置有中心球铰,所述中心球铰的上平面通过上盖固定于下牵引体的上平面,所述上牵引体下部与中心球铰过盈配合,所述下牵引体的两个悬臂各连接有一个牵引拉杆的一端,所述牵引拉杆的另一端与构架横梁相连,所述下牵引体的悬臂外侧设置有用以连接横向油压减振器的横向减振器座。本发明在保证车辆牵引点高度不影响轴重转移的情况下,牵引结构可避开万向轴,满足米轨短轴距万向轴传动系统转向架对空间的限位要求以及机械性能要求。
