Title
(DE) HYDRAULISCHE BREMSANLAGE MIT RADSCHLUPFREGELUNG
(EN) HYDRAULIC BRAKE SYSTEM WITH ANTI-SKID CONTROL
(FR) SYSTEME DE FREINAGE HYDRAULIQUE A REGULATION ANTIPATINAGE
Abstract
(DE)
Die Erfindung betrifft eine hydraulische Bremsanlage mit Radschlupfregelung, mit einem Bremsdruckgeber (2), der über eine Hauptdruckleitung (18) mit wenigstens einer Radbremse (3) hydraulisch in Verbindung steht, mit einer an der Radbremse angeschlossenen Rücklaufleitung (4), die mit einem Vorratsspeicher (16) in Verbindung steht, mit einer Pumpe (17), die eine Druckleitung aufweist, die mit der Hauptdruckleitung (18) hydraulisch verbunden ist, mit wenigstens einem Druckmodulationsventil (1), das den Druckmitteldurchlaß in der Hauptdruckleitung (18) sowie in der Rücklaufleitung (4) entweder sperrt oder geöffnet hält. Das Druckmodulationsventil (1) ist als 3/4-Wegeventil ausgeführt, das in der Grundstellung den Bremsdruckgeber (2) mit der Radbremse (3) verbindet, in den weiteren Schaltstellungen die Druckmittelzufuhr vom Bremsdruckgeber (2) zur Radbremse (3) entweder drosselt oder sperrt und/oder die Radbremse (3) mit der Rücklaufleitung (4) verbindet.
(EN)
A hydraulic brake system with anti-skid control has a brake pressure generator (2) in hydraulic communication through a main hydraulic line (18) with at least one wheel brake (3), a return line (4) connected to the wheel brake and in communication with a hydraulic accumulator (16), a pump (17) with a hydraulic line in hydraulic communication with the main hydraulic line (18), and at least one pressure-modulating valve (1) that keeps the hydraulic medium passage in the main hydraulic line (18) and in the return line (4) either closed or open. The pressure-modulating valve (1) is designed as a 3/4-way valve which in its base position connects the brake pressure generator (2) to the wheel brake (3) and which in the other switching positions either throttles or cuts the hydraulic medium supply from the brake pressure generator (2) to the wheel brake (3) and/or connects the wheel brake (3) to the return line (4).
(FR)
L'invention concerne un système de freinage hydraulique à régulation antipatinage, qui comprend un générateur de pression de freinage (2) relié hydrauliquement à au moins un frein de roue (3), par l'intermédiaire d'une conduite de hydraulique principale (18), une conduite de retour (4) raccordée au frein de roue, qui est reliée à un réservoir d'alimentation (16), une pompe (17) qui comprend une conduite hydraulique en liaison hydraulique avec la conduite hydraulique principale (18), au moins une soupape de modulation de pression (1) qui maintient ouvert ou fermé le passage du fluide hydraulique dans la conduite principale (18) ainsi que dans la conduite de retour (4). La soupape de modulation de pression (1) se présente sous forme de vanne 3/4 voies qui en position initiale, relie le générateur de pression de freinage (2) au frein de roue (3), et dans les autres positions de commutation, réduit ou ferme l'alimentation en fluide hydraulique allant du générateur de pression de freinage (2) au frein de roue (3) et/ou relie le frein de roue (3) à la conduite de retour (4).
