A wear-resistant wheel hub, which relates to the field of wheel hubs. The wear-resistant wheel hub comprises: an outer ring (1) and a mounting shaft (2), wherein a plurality of reinforcing rods (3) are fixed between the outer ring (1) and the mounting shaft (2); a bearing (4) is sleeved inside the mounting shaft (2); an oil injection nozzle (5) is fixed to a side wall of the mounting shaft (2); an oil storage tank (6) is fixed to a surface of the reinforcing rod (3); an oil storage cavity (7) is provided inside the oil storage tank (6); a lubricating oil is provided inside the oil storage cavity (7); and a push plate (8) is movably mounted inside the oil storage cavity (7). By means of providing the lubricating oil in the oil storage cavity (7), under the action of a centrifugal force generated by means of the rotation of the wheel hub, the push plate (8) extrudes the lubricating oil into the interior of the bearing (4), so as to play a role in lubricating the bearing (4), thereby preventing the bearing (4) from wearing out and being damaged due to the generation of a large amount of heat during rotation and greatly prolonging the service life of the bearing (4) of the wheel hub, and thus preventing the service life of the wheel hub from decreasing due to the bearing (4) being damaged and making the wheel hub more wear-resistant.
