AUTOMATIC FRICTION NOISE SUPPRESSION SYSTEM AT MARSHALLING YARDS Russian patent published in 2022 - IPC B61K7/02 B61K3/00 B61K13/00 

FIELD: railway transport.

SUBSTANCE: invention relates to noise suppression at railway transport. The friction noise suppression complex at marshalling yards contains a heated lubrication cabinet, a lubricant supply device including at least four nozzles with lubrication pressure injection devices, at least two speed sensors located before the moderator, at least two speed sensors located after the moderator, at least four wheel detection sensors located next to the nozzles. The lubrication cabinet contains at least one pumping station, a microprocessor control unit, a wireless communication module, a noise level sensor, a compressor, at least one friction modifier storage tank equipped with a modifier heater and a friction modifier level sensor, a receiver and a battery.

EFFECT: as a result, the level of noise impact on the environment is reduced.
