The invention discloses a coupler knuckle, a manufacturing method of the coupler knuckle and a railway vehicle, the coupler knuckle comprises a coupler knuckle part and a connecting part which are connected with each other, the coupler knuckle part comprises a coupler knuckle body, an upper traction flange and a lower traction flange, the upper traction flange and the lower traction flange are arranged on the two sides of the coupler knuckle body respectively, and the upper traction flange is connected with the connecting part. The radius of the upper traction flange is smaller than that of the lower traction flange; and the connecting part is used for being connected with a hook body. As the radius of the upper traction flange is smaller than that of the lower traction flange, when the upper traction flange is used in cooperation with the traction flange of the hook body, the upper traction flange makes contact with the traction flange of the hook body firstly, the situation that the lower traction flange of a weak structure is stressed firstly is avoided, and the problem that when unbalance loading is concentrated on the lower traction flange, cracking is likely to happen is solved to a great extent; the service life of the coupler knuckle is prolonged.
本申请公开了一种钩舌及其制造方法、铁道车辆,其中,钩舌包括相互连接的钩舌部和连接部,所述钩舌部包括钩舌本体、上牵引凸缘和下牵引凸缘,所述上牵引凸缘和所述下牵引凸缘分别设置于所述钩舌本体的两侧,所述上牵引凸缘的半径小于所述下牵引凸缘的半径;所述连接部用于与钩体连接。通过所述上牵引凸缘的半径小于所述下牵引凸缘的半径,与钩体的牵引突缘配合使用时,所述上牵引突缘先与钩体的牵引突缘接触,避免了结构较弱的下牵引突缘先受力,很大程度上解决了偏载集中在下牵引突缘时易发生裂损的问题,从而提升钩舌寿命。
