Abstract:
A wheelset for a gauge-changeable bogie for a rail vehicle, comprising wheels (22) mounted on an axle (26), and gauge-changeable devices mounted on the wheels (22). Each gauge-changeable device comprises a bearing sleeve (212), a bearing assembly, and at least two locking units. The bearing sleeves (212) are provided in axle boxes (21) at the two ends of the axle (26) and the bearing sleeves (212) can axially move along the inner walls of the axle boxes (21); the bearing assembly comprises a first bearing (213) and a second bearing (214), the inner ring of the first bearing (213) is fixedly connected to the periphery of a connecting sleeve (222), and the outer ring of the first bearing (213) is mounted on the inner side of the bearing sleeve (212); the inner ring of the second bearing (214) is fixedly connected to the axle (26), and the outer ring of the second bearing (214) is mounted on an end cover (215); and the locking units are axially provided on axle box bodies (211) at intervals, and the bearing sleeves (212) have at least two locking states. The gauge-changeable bogie which is simple and reliable and can meet a meter gauge limit condition is used, so that interconnection and intercommunication between a standard gauge and a meter gauge of the railway vehicle are achieved. The present invention also relates to a gauge-changeable bogie for the rail vehicle.
