BRAKE DRIVE PNEUMATIC SYSTEM Russian patent published in 2002 - IPC

Abstract RU 2194638 C2

FIELD: transport engineering. SUBSTANCE: invention relates to pneumatic brakes of road vehicles and it can be used in systems with two brake circuits and load sensing valve in rear brake circuit. To provide effective braking of vehicle in emergency in case of failure of front brake circuit, channel is made in parallel with load sensing valve which is provided with built-in valve operated by pressure of first circuit. In case of pressure drop in front circuit, valve automatically opens parallel main line bypassing load-sensing valve. Invention provides disconnection of load-sensing valve at emergency pressure drop in front circuit and operation of brake from rear circuit. EFFECT: improved reliability of braking. 2 dwg
