DEVICE AND METHOD OF RAILWAY HAND BRAKE CHAIN TENSION STATE DETERMINING Russian patent published in 2016 - IPC B61H13/02 F16D66/00 

FIELD: railway transport.

SUBSTANCE: group of inventions relates to railway transport, particularly, to railway hand brakes. Railway hand brake includes tension determination device, housing and force generating chain. Device, according to first version contains element for horizontal linear displacement and element displacement determining facility. In compliance with second version, device comprises sensor, element, sensor target, compressible resilient facility. In compliance with third version, device comprises sensor, element, sensor target, compressible resilient facility. In compliance with fourth version, device comprises casing body, closing element, elongated clamp, lubricating insert, L-shaped bracket, sensor, single one-piece element, target sensor, compressible resilient elastomer, chain guide. In compliance with fifth version contains element, sensor, target, compressible resilient facility. Method of determining tension in railway manual brake chain includes steps, at which: element and sensor are installed, element is displaced and its displacement is determined.

EFFECT: possibility of train hand brake release state determining.
