RAILWAY ROLLING STOCK BOGIE AXLE BOX ASSY (VERSIONS) Russian patent published in 2014 - IPC B61F15/00 B61F15/06 B61F15/20 

FIELD: transport.

SUBSTANCE: axle box comprises adapter, cassette-type bearing, cover and stop plate. Note here that bogie solebars rest via adapters on cassette-type bearings while said bearing is built in said adapter.

Plate width and depth allows fitting of its ends in recesses (slits) between lengthwise kedges at adapter end faces while plate top wide ends are located above adapter lengthwise ledges. In compliance with second version, arc-like bracket is secured at adapter shoulders from the bogie outward side, stalk bolt is rigidly secured to its mid part and directed to under cassette-type bearing.

EFFECT: higher reliability.
