The invention belongs to the technical field of railway vehicle connection, and particularly relates to a freight car coupler. The coupler 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, 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, and 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 a coupling position. The coupler head is provided with a cavity matched with the coupler knuckle in shape at the center of the coupler connecting face, and the coupler knuckle is movably arranged in the cavity. Remote coupling rescue is achieved, 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.
本发明属于铁路车辆连接技术领域,尤其涉及一种货运车钩。它包括钩体、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。本发明实现远程连挂救援,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。
