The invention discloses a coupler yoke and a coupler draft gear which are used in the field of carriages of a railway and aim at solving the problems of lower strength, low safety and reliability and the like in the prior art. The coupler yoke of the invention comprises a hollow yoke body with the cross section being in a long concentric-square shape, the inner side surface of the one end of the hollow yoke body is a bearing surface, and at least part of the heavy loading area of the bearing surface protrudes outwards relatively to the end surface of the light loading area, The coupler yoke is used for connecting couplers between the carriages of a train, so that the carriages are connected to form the train for transmitting the tractive force in the transportation; the distribution pattern of the existing bearing surface is changed due to the arrangement of a middle groove, so that the middle part with weak anti-bending and anti-deformed capability of the bearing surface is separated from the bottom surface of the buffer to reduce the load force on the middle part of the bearing surface, thereby improving the strength of the coupler yoke, reducing occurrence of the crack and the fracture in the using process of the coupler yoke, guaranteeing the connection reliability and the travelling safety of the train and ensuring the exchangeability between the coupler yoke in the invention and the existing coupler yoke. |
