END THRUST BEARING DAMPER Russian patent published in 2010 - IPC B61F5/16 

FIELD: transport.

SUBSTANCE: car bogie end thrust bearing damper represents cup 1 that repeats the shape of end thrust bearing and has central bore. Damper comprises case-shaped ring 3 that has openings with flanges arranged all over its perimetre to hold lateral movable covers in place under which arranged are multilayer lateral flexible hysteresis stacks made up of steel corrugated plates. Circular multilayer flexible hysteresis stacks (10, 11) of plates with radial corrugation are placed on cup bottom under circular cover 9 held in place by circular flanges of central 4 and taper case-shaped rings. All corrugated plates are coated with a thin coat of fluid that features damping properties. Said tapered and case-shaped rings are rigidly fixed inside cup. Lateral movable covers extend above tapered case-shaped ring. Movable circular cover extends above tapered and central case-shaped rings by a distance equal to maximum possible deformation of corrugated plate stacks. Heatproof coat is applied on surfaces of cup and covers that interact with flexible hysteresis stacks.

EFFECT: higher efficiency of damping, longer life.
