Title (EN) PASSIVE ACCUMULATOR-FREE HYDRAULIC BRAKING SYSTEM
(FR) SYSTÈME DE FREINAGE HYDRAULIQUE PASSIF SANS STOCKAGE
(DE) PASSIVES SPEICHERLOSES HYDRAULISCHES BREMSSYSTEM
Abstract:
(EN) The invention relates to a passive accumulator-free hydraulic braking system in which a hydraulic pump (2) driven by a motor (1) generates an oil pressure that feeds a pressure line (5) of a hydraulic circuit (6) via a check valve (4), the pressure line (5) supplying a hydraulic feed pressure to at least one brake caliper (10) that is connected thereto. A spring-biased damping element (12) for temporarily buffering a leakage-compensating oil volume is connected to the pressure line (5) of the hydraulic circuit (6).
(FR) L'invention concerne un système de freinage hydraulique passif sans stockage dans lequel une pompe hydraulique (2) entraînée par un moteur (1) génère une pression d'huile, qui, au moyen d'un clapet anti-retour (4), alimente une conduite de pression (5) d'un circuit hydraulique (6), qui fournit à au moins un étrier de frein (10), connecté audit circuit hydraulique, une pression d'alimentation hydraulique, un élément amortisseur (12) sollicité par une force de ressort étant connecté à la conduite de pression (5) du circuit hydraulique (6) pour un tamponnement intermédiaire d'un volume d'huile de compensation de fuite.
(DE) Die Erfindung betrifft ein passives speicherloses hydraulisches Bremssystem, bei dem eine über einen Motor (1) angetriebene Hydraulikpumpe (2) einen Öldruck erzeugt, der über ein Rückschlagventil (4) eine Druckleitung (5) eines Hydraulikkreises (6) speist, welche mindestens einen hieran angeschlossenen Bremssattel (10) mit einem hydraulischen Speisedruck versorgt, wobei an der Druckleitung (5) des Hydraulikkreises (6) ein federkraftbeaufschlagtes Dämpfungselement (12) zur Zwischenpufferung eines Leckageausgleich-Ölvolumens angeschlossen ist.
