Abstract

TITRE : « Système de freinage » Système de freinage de véhicule comprenant une pédale de frein (1) pour activer les freins (FR1,2) par l’intermédiaire d’un circuit hydraulique (C1,2) reliant un accumulateur de pression (AC1, 2) chargé de liquide de frein sous pression et relié par une ligne d’alimentation (SP1,2) à une vanne de frein (EVFR1,2) en forme de distributeur à tiroir(10) en amont des freins de roue (FR1,2), et leur fournissant une pression régulée en fonction de la demande de freinage exercée sur la pédale de frein 1, la pédale de frein (1) est reliée en parallèle au tiroir de distributeur (10), par une liaison mécanique (4, 5) directe et une liaison électrohydraulique (6, 61, 62, 63) qui génère un signal pilote hydraulique (SPH1,2) à partir de l’actionnement de la pédale de frein(1), pour réguler la pression du liquide de frein appliquée aux freins de roue (FR1,2). Figure 1TITLE: "Braking system" Vehicle braking system comprising a brake pedal (1) to activate the brakes (FR1,2) via a hydraulic circuit (C1,2) connecting a pressure accumulator (AC1 , 2) charged with pressurized brake fluid and connected by a supply line (SP1,2) to a brake valve (EVFR1,2) in the form of a spool valve (10) upstream of the wheel brakes (FR1 , 2), and supplying them with a regulated pressure as a function of the braking demand exerted on the brake pedal 1, the brake pedal (1) is connected in parallel to the valve spool (10), by a mechanical link (4 , 5) direct and an electro-hydraulic link (6, 61, 62, 63) which generates a hydraulic pilot signal (SPH1,2) from the actuation of the brake pedal (1), to regulate the pressure of the brake fluid. brake applied to the wheel brakes (FR1,2).
