VORRICHTUNG ZUR BETÄTIGUNG EINES SCHIENENFAHRZEUG-BREMSSYSTEMS, UND MIT EINER SOLCHEN BETÄTIGUNGSVORRICHTUNG AUSGESTATTETES SCHIENENFAHRZEUG

摘要

The invention relates to an actuation device (4) of a rail braking system, comprising a valve mechanism (16) and a control mechanism (13) configured to act on said valve mechanism, said actuation device being configured to admit at least one braking position in which said valve mechanism acts on at least one brake valve (109a-b) of said valve mechanism to actuate said system and / or at least one de-braking position in which said valve mechanism acts on at least one brake release valve (110a-b) of said valve mechanism to actuate said system; said control mechanism comprises at least one cam wheel (24) which is movable in rotation and which is provided with at least one contact face (88) having a predetermined profile and being configured to act directly on said brake valve or of braking as a function of the direction of movement in rotation of said cam wheel and of the position of said device.
