CONNECTION OF SIDE FRAME WITH OVERSPRING BEAM OF THREE-MEMBER BOGIE OF FREIGHT CAR Russian patent published in 2004 - IPC

FIELD: railway transport; freight cars.

SUBSTANCE: invention relates to rail vehicles, particularly, to connections of side frame with overspring beam of freight car three-member bogie. Connection contains side frame 1 and overspring beam 3 resting on spring set 4, consisting of springs, through vibration dampers. Vibration dampers contain angle brackets 5 and knife-edge supports 6 arranged along overspring beam with equal displacements of halves of spring set under action of resultant forces of spring on which angle brackets rest. Vertical flange 7 of each angle bracket is provided with friction cover plate 8 and is pressed to friction strip 9 secured on side frame.

EFFECT: improved running qualities of bogie owing to optimum and stable damping of vibrations and reduced tendency to "overswinging" of side frames.
