RAIL VEHICLE DRIVING MOTOR TURNING BOGIE Russian patent published in 1996 - IPC

FIELD: rail transport; tramways. SUBSTANCE: bogie has frame 1 formed by interconnected longitudinal beams 1a and cross beams 1b located inside space limited by wheel disks of wheelsets 3 set into motion by its own traction motor and installed for vertical displacement on ends of longitudinal beams 1a. Bogie has also hollow shafts 7 enclosing the axles of wheelsets with clearance, cradle 13 placed across bogie longitudinal axis and resting on longitudinal beams 1a of frame 1 through secondary springs, and car body turnable journal whose support is coupled with cradle 13. Traction motors 10 are arranged between longitudinal beams 1a of frame 1 and are kinematically coupled through axle drives 4 with corresponding wheelsets 3. Bogie frame 1 is made up of two parts, T-shaped in plan, each including rigidly coupled longitudinal beam 1a and cross beam 1b. Parts of frame are interconnected in zone of joint of longitudinal beam 1a and cross beam 1b by means of two supports arranged diagonally in plan relative to longitudinal and cross axes of bogie. Ends of longitudinal beams 1a rest at both sides on hollow shaft of wheelset 3 through springs and mounting members. Each traction motor 10 is secured under corresponding cross beam 1b. Each axle drive 4 is locked against turning relative to shaft 7 one end of which is coupled with upper portion of cross beam 1b and the other, with housing of axle drive 4 resting on hollow shaft 7. EFFECT: enlarged operating capabilities. 5 cl, 3 dwg
