AXLE LINER OF CAR BOGIE SIDE FRAME Russian patent published in 2016 - IPC B61F5/26 

FIELD: metallurgy.

SUBSTANCE: axle liner is made of sheet metal with wear-resistant properties in form of u-shaped box opening and has support wave surfaces, interacting with support surfaces of jaw opening, and surfaces, tightly adjacent to cylindrical surfaces of axle box housing. Liner also comprises at least three local zones of variable stiffness, provided with grooves, made perpendicular to support surfaces of lining, and in contact with wavy gaskets of constant or variable length on thickness, arranged between axle box housing and axle liner.

EFFECT: such design of liner makes it possible to damp considerable force of impact action, reducing load transmitted to axle box housing in a canine jaw opening, reduced wear of support surfaces of axle box housing and side frame, redistributes load between rows of bearings.
