The invention relates to the technical field of railway vehicles, and discloses a gauge-changeable bogie and gauge-changeable wheel system, which comprises an axle and two wheels which are symmetrically arranged. The outer walls of the two ends of the axle are integrally sleeved with mounting bases; the inner walls of the wheels are fixedly sleeved with connecting sleeves; the connecting sleeves are stably clamped and sleeved outside the mounting bases; a connecting housing is fixedly clamped and sleeved outside each connecting sleeve; the outer wall of the connecting housing is rotationally sleeved with a fixation housing through a plurality of ball bearings; a cavity is formed in the axle corresponding to the mounting base; the inner walls of the opposite sides of the left side and the right side of the cavity are rotationally connected with the same adjusting screw through ball bearings; grooves are formed in the two ends of the axle; driving motors are fixedly arranged in the grooves; output shafts of the driving motors are fixedly connected with one ends of the adjusting screws; and the rod walls of the adjusting screws are evenly sleeved with a plurality of movable screw rings in a threaded mode. The system can stably limit the wheels, is quick and convenient to operate, and facilitates the fixation, installation and use of the wheels.
