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

FIELD: railway transport.

SUBSTANCE: proposed rail traction vehicle contains body of frame 1, traction bogies 3 with wheelsets 5 and axle boxes 6, axle box carriers 9 connecting axle boxes of wheelsets with frames 8 of bogies, pivots or brackets, tie-rods connecting bogies with body or frame. Body or frame is provided with pivots 13 or brackets, being connected with pivots 14 or brackets of bogie frames, by tie-rods 17 arranged in middle vertical longitudinal plane of rail traction vehicle between axles of wheelsets, with hinge joints 18 with grease or liquid lubricant in space of pivots' and tie-rods or rubber-metal hinge joints (silent blocks) with provision of rotation around three axes of each hinge joint or one hinge joint of each tie-rod relative to three axles, and second one, relative to vertical and cross axes.

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