FREIGHT RAILWAY CAR BOGIE WITH FRICTION DAMPING Russian patent published in 2016 - IPC B61F5/12 

FIELD: transportation.

SUBSTANCE: freight railway car three component bogie consists of two frame sides distant from each other in radial direction, and bolster, interconnecting said frame sides. Bolster is maintained by spring suspension working springs, and control springs enable support of friction pads. Both types of friction pads have gaps, which allow friction pad to perform lateral movements across bolster or across frame side. During lateral displacement spacer from low friction material is used, provided between bolster and friction pad; or spacer from low friction material, provided between friction pad and wear-resistant plate resting against frame side.

EFFECT: low friction material low sliding resistance allows transfer energy to dissipate in lateral separating gap.
