DRIVEN WHEELED SWIVEL BOGIE OF A RAIL VEHICLE, PRIMARILY A TRAM WITH A 100% LOW FLOOR LEVEL, WITH A TRACK WIDTH OF 1,000 mm Russian patent published in 2021 - IPC B61F3/04 

FIELD: railway transport.

SUBSTANCE: invention relates to the field of rail transport, in particular, to driven wheeled bogies of rail vehicles, primarily trams, with a 100% low floor level, with a track width of 1,000 mm. The bogie comprises a frame composed of two half-frames, and two wheelsets. Each half-frame includes one longitudinal beam and one transverse beam. The beams are interconnected hingedly. Box bodies with bearings are installed on the outside of the wheels. Each box body is spring-loaded relative to the longitudinal beam. Each wheelset is driven to motion and braked by an engine. The engines are kinematically connected on one side via a coupling with a reducer gearbox, and on the other side with a disk brake. The engines are secured laterally on the outside of the longitudinal beam. The reducer gearboxes are installed on an axle on the outside of the frame and secured laterally on the longitudinal beam. A bolster with a bearing is located transversely on the frame between the transverse beams and is supported with springing by the longitudinal beams.

EFFECT: possibility of operation of the bogie on urban lines with a track width of 1,000 mm and curve radii of 16 m is provided.
