LOCOMOTIVE NON-PEDESTAL BOGIE Russian patent published in 2018 - IPC B61C15/00 

FIELD: transportation.

SUBSTANCE: invention relates to railway transport, particularly, to non-pedestal locomotive bogies. Non-pedestal locomotive bogie comprises a frame with traction electric motors with wheel pairs mounted on it, axle boxes and spring suspension. On the frame, in the transverse plane, parallel to the axes of the wheel pairs of the extreme wheel-motor blocks and in its middle part, spring-loaded splined bushings are movably mounted in the guides. Bushings contact the curvilinear disks rigidly fixed to the shafts of the moment hydraulic cylinders. Hydraulic cylinders are mounted on the frame of the bogie and are connected by pipelines with a slide valve interacting with the body of the locomotive, and with the hydraulic power unit located in the said body. In the hydraulic cylinders, slit sections of the elastic rods, which are mounted with the possibility of elastic angular movements in the supports of the bogie frame, are movably disposed. Rods are equipped with levers, the ends of which are made in the form of forks, interacting with the fingers, rigidly fixed on the end surfaces of the axle boxes of wheel pairs.

EFFECT: higher reliability of locomotive bogie.
