Title (EN) HYDRAULIC BRAKING SYSTEM
(FR) SYSTÈME DE FREINAGE HYDRAULIQUE
Abstract:
(EN) A hydraulic braking system including: a cylinder device (66) including: a pressurizing piston (104); a rear chamber (136) and a front pressure chamber (112) on opposite sides of the pressurizing piston (104); a brake cylinder (52RL,52RR) coupled to the front pressure chamber (112); a regulator (182) including: a control piston (204); an input chamber (212) provided at a rear of the control piston (204); and an output chamber (214) coupled to the rear chamber (136) in front of the control piston (204); and an input-hydraulic-pressure control device (250/SLA,252/SLR) configured to supply working fluid to the input chamber (212) to produce hydraulic pressure in the output chamber( 214) and including: a high-flow-rate supply unit (Sl-Sll) configured, when an operation of the regulator (182) is started, to supply the working fluid to the input chamber (212) at a set flow rate (q); and a low-flow-rate supply unit (S12,S13) configured, when the high- flow-rate-supply is finished, to supply the working fluid to the input chamber (212) at a flow rate less than the set flow rate (q).
(FR) Système de freinage hydraulique comprenant : un dispositif de cylindre (66) constitué d'un piston de mise sous pression (104); d'une chambre arrière (136) et d'une chambre de pression avant (112) situés sur les côtés opposés du piston de mise sous pression (104); d'un cylindre de frein (52 RL, 52 RR) accouplé à la chambre de pression avant (112);d'un régulateur (182) qui comprend : un piston de commande (204); d'une chambre d'admission (212) prévue à l'arrière du piston de commande (204); et d'une chambre de sortie (214) accouplée à la chambre arrière (136) devant le piston de commande (204); et d'un dispositif de commande d'entrée de la pression hydraulique (250/SLA, 252/SLR) conçu pour alimenter en fluide de travail la chambre d'admission (212) afin de produire une pression hydraulique dans la chambre de sortie (214) et comprenant: une unité d'alimentation à débit élevé (Sl-Sll) conçue, lorsqu'une opération du régulateur (182) est démarrée, pour alimenter la chambre d'admission (212) en fluide de travail selon un débit d'écoulement défini (q); et d'une unité d'alimentation à faible débit (S12, S13), conçue, lorsque l'alimentation à débit élevé est terminée, pour alimenter la chambre d'entrée (212) en fluide de travail avec un débit d'écoulement inférieur au débit d'écoulement défini (q).
