The invention belongs to the technical field of vehicle connection, and particularly relates to a highway-railway freight vehicle connecting device. The car coupler comprises a car coupler body and an impact seat, the car coupler body is connected with the impact seat through a coupler yoke pin, the impact seat is welded to a car chassis, the car coupler body comprises a coupler body, a coupler knuckle, an uncoupling rod, a tension spring rod and a tension spring, the coupler body comprises a coupler head, a coupler body and a coupler tail, and a convex cone structure and a concave cone structure are arranged on the connecting face of the front end of the coupler head in a bilateral symmetry mode. The curved surface of the concave cone structure of one freight car coupler guides and envelops the convex cone structure of the other freight car coupler to enter the coupling position, a cavity matched with the coupler knuckle in shape is formed in the position, at the center of the car coupler connecting face, of the coupler head, and the coupler knuckle is movably arranged in the cavity. The space requirements that the upper portion of a vehicle is assembled with a container for transportation and the lower portion of the chassis is connected with a tractor head are met, the self-weight is small, the self-weight of the vehicle can be reduced, the coupling gap is small, the longitudinal impulse level of the vehicle can be improved, the dynamic performance is improved, and the space profile is small.

    本发明属于车辆连接技术领域,尤其涉及一种公铁两用货运车辆连接装置。它包括车钩和冲击座,所述车钩通过钩尾销与冲击座连接,所述冲击座与车辆底架焊接,所述车钩包括钩体、钩舌、解钩杆、拉簧杆和拉簧,所述钩体包括钩头、钩身和钩尾,所述钩头前端连接面处左右对称设置一个凸锥结构和一个凹锥结构,一个货运车钩的凹锥结构的曲面引导和包络另一个货运车钩的凸锥结构进入连挂位置,所述钩头在车钩连接面中心处设有与钩舌形状相匹配的空腔,所述钩舌活动设于空腔内。本发明满足车辆上部装配集装厢运输和底架下部连接牵引车车头的空间要求,自重小,可降低车辆自重,连挂间隙小,可改善车辆纵向冲动水平,提高动力学性能,空间轮廓小。
