摘要： Disclosed are an independent wheel set (1) directly driven by switched reluctance electric motors, and a single-axle bogie. The independent wheel set (1) comprises an axle bridge (11), wherein switched reluctance electric motors (13) are respectively installed at two ends of the axle bridge (11); an inverter (13-4) and a stator (13-2) are installed on a mandrel (13-1) of each switched reluctance electric motor (13); the inverter (13-4) is located at an end of the stator (13-2); a rotor (13-3) is installed on an inner side of the housing (13-5) of each switched reluctance electric motor (13); the mandrels (13-1) are connected to the axle bridge (11); and the housing (13-5) is fixedly connected to a wheel rim (12). The independent wheel set (1) changes the structure of a traditional electric motor by means of the inverters (13-4), such that the mandrels (13-1) are immovable and assume the function of an axle; and the housing (13-5) of each electric motor rotates, and when the housing (13-5) of the electric motor and the wheel rim (12) are integrated together, the electric motor (13) and the wheel rim (12) constitute a wheel driving unit, such that a left wheel driving unit and a right wheel driving unit form the independent wheel set (1) by means of the axle bridge (11), thereby providing power for the bogie.

摘要： A framework (10) comprises a longitudinal beam (12), a crossbeam and a mounting base; a groove (13) is provided on the longitudinal beam (12), and the opening of the groove (13) faces toward the outer side of the framework (10); a current-receiving apparatus case (1) is connected to the framework (10) by means of the mounting base (9), and the mounting base (9) is fixed inside the groove (13) by means of welding or fasteners.A current-receiving apparatus is also related to, which comprises a current-receiving apparatus case (1), rotary arms (2) and collector shoes (3); the upper end of the rotary arm (2) is hinged to the current-receiving apparatus case (1); the collector shoe (3) is connected to the lower end of the rotary arm (2); the current-receiving apparatus case (1) has a space for the rotary arm (2) to tilt; the rotary arm (2) can drive the collector shoe (3) to rotate about the hinged point until same comes into contact with a side surface of a third rail (4), or rotate until same comes into contact with a bottom surface of the third rail (4), so as to achieve a current-receiving means that integrates the bottom surface and side surface with the same bogie, and allow same to adapt to changes in the current-receiving means due to limited space of a railway bridge, thus ensuring the normal operation of vehicles.
