CONNECTION OF OVERSPRING BEAM WITH SIDE FRAMES OF THREE-MEMBER BOGIE AND WITH MAIN FRAME OF CAR Russian patent published in 2006 - IPC B61F5/06 B61F5/16 

FIELD: railway transport.

SUBSTANCE: invention relates to rail vehicles, particularly, to design members of their bogies and connection of overspring beam with side frames 1 of three-member bogie and with main frame of car. Aperture 2 is made in each side frame, between upper belt 3 and lower belt 4 of which springs 5 of spring suspension are fitted to carry overspring beam 6. Bogie center plate with hole for pivot is made on overspring beam in middle, and side supports are installed to carry main frame of car. Opening in bogie center plate is made through overspring beam in vertical down to lower belt, and elongated pivot is passed through opening with slide fit whose lower end is fixed in bushing, and upper end of pivot is arranged over support surfaces of body pivot bearing of car main frame. Vertical holes are made coaxially in middle of aperture of each side frame in upper and lower belts, and coaxial hole is made in overspring beam. Rod 18 is fitted in said holes along longitudinal axis of bogie with slide fit, and side clearances are made in cross direction relative to said axis in hole of overspring beam at each side of rod. Said rod is passed through lower belt and is secured under belt.

EFFECT: improved operating properties of bogie.
