DIESEL LOCOMOTIVE NON-PEDESTAL BOGIE Russian patent published in 2018 - IPC B61F5/00 

FIELD: transportation.

SUBSTANCE: invention relates to rail vehicles, in particular to locomotives non-pedestal bogies. Locomotive non-pedestal bogie consists of frame with wheeled-motor blocks mounted on it. Axle boxes the of wheel pairs are spring-loaded relative to the frame by helical compression springs and with the help of shackle links are bound with it. On each of bogie boxes glasses are fixed. Inner vertical surfaces of glasses are provided with slots interconnected with reciprocal slots of hollow rod. Rod is made of elastic material and inside it are made splines, interacting with reciprocal splines of solid cross-section of rod. Both bars are equipped with levers with forks made of elastic material. Levers cover fingers and are rigidly fixed on trolley frame. Ends of both elastic rods are spring-loaded with respect to bottom of glasses by sets of helical compression springs.

EFFECT: it is possible to reduce undercut of wheels crests of wheel pairs when passing them both straight and curved sections of track.
