BEARING Russian patent published in 2022 - IPC B61F5/14 

FIELD: bearings.

SUBSTANCE: bearing contains a body, a cap and an elastic element. The bearing body is mounted on the bearing located on the bolster of the bogie and made integral with it, and contains a supporting plate and a side wall bent downwards, extending from the supporting plate to the lower face, and extending outward from the side wall side protrusion. The downwardly folded side wall includes two opposite sides and two opposite ends, each adjacent side and end being connected at the corners, and also includes an outward-facing wear-resistant contour and forms an outer body portion and an inner body portion designed and configured to partially placement of the bearing support in the inner part of the body. The elastic element is engaged with the body with its lower end and is located on the side ledge of the body. The bearing cap, designed to interact with the mating part of the car body, is engaged with the upper end of the elastic element and includes an upper bearing surface and a lower surface made with a recess with an upper thrust surface and a limiting vertical wall located between the lower surface and the upper abutment surface and including an inwardly facing wear-resistant contour, and is configured to accommodate the outer part of the body in the recess of the cap. There is a technological gap between the wear-resistant contour of the limiting vertical wall of the cap recess and the wear-resistant contour of the side wall of the body.

EFFECT: such a design of the proposed bearing and the placement of its structural elements in the process of operation makes it possible to implement conditions that simplify assembly and increase reliability in operation.
