COMB LUBRICATION SYSTEM Russian patent published in 2018 - IPC B61K3/02 

FIELD: vehicles.

SUBSTANCE: invention relates to the rail vehicle wheel rim lubrication system. Fixed on the wheel bushing rim lubrication system is made in the form of a body filled with directed towards the lubricated friction surface solid antifriction elements. Wherein the body is made in the form of connected to each other with the possibility of their separation accumulating and guiding parts. At that, the body guiding part is made with the drive mechanism arrangement in its tail part, for example, connected to the stem spring, pressing the solid antifriction element to the lubricated surface with possibility of the drive mechanism fixation in the set position, if it is necessary to ensure of solid antifriction elements from the body accumulating part unimpeded supply. Body accumulating part is made with the guaranteed slope relative to the body guide part, ensuring the solid antifriction elements free movement towards the body guide part. At that, two of the above lubricating elements are located in the body guide part, and all the rest are in the accumulating part. As the pressed against the lubricated surface solid antifriction element wears, its place is occupied by the second solid antifriction element, located in the ensuring pressing guiding part, and its place is occupied by located in the body accumulating part solid antifriction element.

EFFECT: as a result, the rail transport wheels rims lubrication efficiency is increasing.
