Title (EN) BRAKING CONTROL SYSTEM
(FR) SYSTÈME DE COMMANDE DE FREINAGE
Abstract:
(EN) A braking control system comprising a first source of pressurised fluid (82a), a second source of pressurised fluid (82b, 90), a modulator (70), a brake actuator (10), and a plurality of valves (84, 94, 96, 98), the modulator (70) having a supply inlet (72) which may be connected to either of the sources of pressurised fluid via a first fluid flow line which extends between a first one of the valves (84) and the supply inlet (72), and a control inlet (78) which may be connected to either of the sources of pressurised fluid via a second fluid flow line and a second one of the valves (94), a delivery port (74) which is connected an inlet (11) of the actuator (10), and an exhaust outlet (76) which vents to a low pressure region, the modulator (70) being operable to move between a build position in which flow of fluid from the supply inlet (72) to the delivery port (74) is permitted whilst flow of fluid through the exhaust outlet (76) is substantially prevented, and an exhaust position in which flow of fluid between the delivery port (74) and the exhaust outlet (76) is permitted, whilst flow of fluid through the supply inlet (72) is substantially prevented, wherein a portion of the fluid flow line connecting the second source of pressurised fluid (82b, 90) to the first valve (84) also provides a proportion of the connection between the second source of pressurised fluid (82b, 90) and the second valve (94).
(FR) La présente invention concerne un système de commande de freinage qui comprend une première source de fluide sous pression (82a), une seconde source de fluide sous pression (82b, 90), un modulateur (70), un actionneur de frein (10) et une pluralité de soupapes (84, 94, 96, 98), le modulateur (70) comportant une entrée d'alimentation (72) qui peut être raccordée à l'une ou l'autre des sources de fluide sous pression par le biais d'un premier tuyau d'écoulement de fluide qui s'étend entre une première soupape parmi les soupapes (84) et l'entrée d'alimentation (72), ainsi qu'une entrée de commande (78) qui peut être raccordée à l'une ou l'autre des sources de fluide sous pression par le biais d'un second tuyau d'écoulement de fluide et d'une deuxième soupape parmi les soupapes (94), un orifice de distribution (74) raccordé à une entrée (11) de l'actionneur (10) et une sortie d'échappement (76) qui évacue vers une zone basse pression, le modulateur (70) pouvant se déplacer entre une position d'établissement dans laquelle l'écoulement du fluide entre l'orifice d'alimentation (72) et l'orifice de distribution (74) est autorisé tandis que l'écoulement du fluide par la sortie d'échappement (76) est sensiblement empêché, et une position d'échappement dans laquelle l'écoulement du fluide entre l'orifice de distribution (74) et la sortie d'échappement (76) est autorisé, tandis que l'écoulement du fluide par l'orifice d'alimentation (72) est sensiblement empêché, une partie du tuyau d'écoulement de fluide raccordant la seconde source de fluide sous pression (82b, 90) à la première soupape (84) fournissant également une proportion du raccord entre la seconde source du fluide sous pression (82b, 90) et la seconde soupape (94).
