Title
(EN) VEHICLE BRAKING SYSTEM
(FR) SYSTÈME DE FREINAGE DE VÉHICULE
Abstract
(EN)
This invention concerns a vehicle braking system (10). The system includes at least one service brake (12.1, 12.2) and pressurising means (16) for providing pressurised fluid for controlling actuation of the brake between its disengaged and engaged positions. The system may include a relay valve (22) located between the pressurising means (16) and the brake for controlling operation of the brake. The system may also include a pressure sensing device (46) for automatically actuating a failsafe brake (50.1, 50.2) of the vehicle upon detection of a pressure differential in the system.
(FR)
La présente invention concerne un système de freinage de véhicule (10). Le système comprend au moins un frein de service (12,1, 12.2) et des moyens de mise sous pression (16) destiné à fournir un fluide sous pression pour commander l'actionnement du frein entre ses positions désengagée et engagée. Le système peut comprendre une valve relais (22) située entre les moyens de mise sous pression (16) et le frein pour commander le fonctionnement du frein. Le système peut également comprendre un dispositif de détection de pression (46) pour actionner automatiquement un frein à sécurité intégrée (50.1, 50.2) du véhicule lors de la détection d'une pression différentielle dans le système.
