The invention provides an axle box device for a variable gauge locomotive wheelset, and relates to the technical field of locomotive production and manufacturing. The axle box device for the gauge-changeable locomotive wheelset comprises an axle box beam, a plurality of locking grooves and a plurality of locking blocks, wherein the inner wall of the axle box beam is provided with a plurality of locking grooves along the axial direction of the axle box beam; the axle box body is arranged in the axle box beam, and a locking bulge is arranged on the outer wall of the axle box body; at least part of the sliding mechanism is arranged in the axle box body and penetrates through wheels of the gauge-changeable locomotive wheelset, and an axle of the gauge-changeable locomotive wheelset penetrates through the sliding mechanism; the axle box bearing is arranged outside the sliding mechanism in a sleeving manner and is arranged between the sliding mechanism and the axle box body; the sliding mechanism is configured to drive the wheel, the axle box bearing and the axle box body to move in the axial direction of the axle, so that the locking protrusion is selectively connected with one of the locking grooves in a clamped mode, and the track gauge is changed. The axle box device for the variable gauge locomotive wheelset is simple in structure and high in reliability.
