The invention provides a draw bar which comprises a metal assembly and a fiber assembly. The metal assembly comprises two metal pieces, a plurality of protruding part sets are arranged on the outer surfaces of the two metal pieces, and the protruding part sets are arranged around the outer surfaces of the metal pieces; and the fiber assembly comprises continuous fiber filaments, the continuous fiber filaments are wound around the protruding part sets to form the fiber assembly, the fiber assembly wraps at least part of the metal pieces, the protruding part sets penetrate through at least partof the fiber assembly, and the two metal pieces are connected through the fiber assembly. According to the draw bar, the cost can be reduced, the weight of the draw bar is effectively reduced, the light weight, energy conservation and consumption reduction of a rail train are facilitated, and meanwhile, the corrosion resistance is also improved. The invention further provides a car coupler and a draw bar manufacturing method.

    本发明提供一种牵引杆,包括:金属组件,所述金属组件包括:两个金属件,两个所述金属件外表面上设置有多个突出部组,多个所述突出部组围绕所述金属件外表面设置;纤维组件,所述纤维组件包括:连续纤维丝,所述连续纤维丝围绕多个所述突出部组进行缠绕形成所述纤维组件,所述纤维组件包绕至少部分所述金属件,所述突出部组穿过至少部分所述纤维组件,所述纤维组件连接两个所述金属件。本发明提供的牵引杆,能够降低成本,且有效降低牵引杆本身的重量,有利于轨道列车的轻量化及节能降耗,同时也提高了耐腐蚀性能。本发明还提供一种车钩及牵引杆制造方法。
