Abstract
A coupler yoke and a coupler draft gear 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 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.
