The invention relates to a locomotive wheelset, in particular to a wheelset, making contact with a rail, on a locomotive. The locomotive wheelset is characterized in that an axle comprises two first cylinders and a second cylinder, the diameter of each first cylinder is smaller than that of the second cylinder, the diameter of the second cylinder is larger than the inner diameter of each wheel hub hole, the two first cylinders are located at the two ends of the second cylinder respectively, and the first cylinders are in concentric connection with the second cylinder; radial protrusions are arranged on the inner circumferential surface of each wheel hub hole, radial grooves matched with the protrusions are formed in the outer side wall of each first cylinder, the first cylinders are sleeved with the wheel hub holes correspondingly, and the protrusions of the wheel hub holes are matched with the grooves of the first cylinders in a one-to-one correspondence mode; threads are arranged at the outer ends of the first cylinders respectively, sustaining nuts are arranged on the threads respectively in a matched mode, and when the sustaining nuts are fastened, the inner side faces of wheel hubs are in close fit with the ends, connected with the corresponding first cylinders, of the second cylinder respectively. According to the locomotive wheelset, when a wheel needs to be replaced, detachment is convenient, and time consumption is low.
