PROCEDURE FOR ABSORPTION OF "BUFFER" FORCE IMPACT (VERSIONS) Russian patent published in 2010 - IPC F16F1/373 B61G11/00 

FIELD: machine building.

SUBSTANCE: group of inventions is implemented in central and axle-box spring suspension of railroad vehicle truck, and also as buffer of carriage. An element out of elastic material is used for dispersion of impact energy in the procedure for absorption of energy of impact force. The applied element corresponds to a conic-shaped ring. The conic-shaped ring operates to reversing in a state or before the state, under which force in its cross section acting in the direction opposite to the direction of applied load is less, than force in the said section acting in the perpendicular direction. The buffer contains the elastic conic-shaped ring. The conic-shaped ring with its bigger base is placed in a case; angle of incline of equal force in ring cross section can be decreased relative to any of its bases to less, than 45° or within the range 0°<γ≤45°.

EFFECT: simplified design of buffer, increased service life and efficiency.
