1. A hollow axle structure comprises an axle (19) for mounting corresponding wheels (1, 21) through bearings (6), and is characterized in that an outer ring (13) of each bearing (6) is directly and fixedly connected with an inner edge of a hub (3) of the corresponding wheel (1, 21), and an inner ring (12) of each bearing (6) is directly and fixedly connected with an outer wall surface of the axle (19);

  • the axle bridge (19) is of an integral hollow tubular structure and is used for bearing bending moment loads generated by transverse forces and vertical forces of the wheels (1,

         21);

    the bearing (6) supported on the axle (19) is located in a bore of the hub (3) of the respective wheel (1,

         21);

    a torsion bar (20) sheathed in the axle (19) and fixedly connected with the corresponding transmission disc (7), wherein the end teeth (4) of the wheel hub (3) of the corresponding wheel (1,

         21) are tightly meshed with the end teeth (4) of the corresponding transmission disc (7);

    the torsion bar (20) is fixedly connected with the transmission disc (7) and the wheels (1,

         21) to bear torque load, so that the wheels (1,

         21), the transmission disc (7) and the torsion bar (20) can synchronously rotate around the axle center;

    the left end of the hollow axle bridge structure is symmetrically arranged relative to the right end.
