DEVICE FOR LONGITUDINAL COUPLING OF BOGIES WITH BODY OF RAILWAY TRACTION VEHICLE Russian patent published in 2006 - IPC B61F5/02 B61F5/16 

FIELD: railway transport.

SUBSTANCE: invention relates to devices for longitudinal coupling of bogies with railway traction vehicle body. Proposed railway traction vehicle has body or frame 1, traction bogies 3 with wheelsets 5 and axle boxes 7. Body or frame are provided with pivots or brackets 15 with crossmembers 21 secured for rotation around vertical axle and connected by carriers or tie-rods 16 with axle-boxes, with hinge joints 17 filled with grease or liquid lubricant in spaces of pivots, crossmembers and tie-rods, or rubber-metal joints (silent blocks) to provide rotation around three axles of each hinge joint or one hinge joint of each tie-rod relative to three axles, and second one, relative to vertical and cross axle. According to other design version, crossmembers mentioned above are connected with pivots 14 or brackets secured on bogies.

EFFECT: improved traction properties of railway traction vehicles, reduced dynamic loads, increased tolerable speeds of running, reduced resistance to running, consumption of fuel and wear of parts, reduced overall dimensions of bogie, improved utilization of underbody space.
