Title
(EN) METHOD AND APPARATUS FOR CONTROLLING A BRAKING SYSTEM
(FR) PROCEDE ET APPAREIL POUR COMMANDER UN SYSTEME DE FREINAGE
Abstract
(EN) Method and apparatus for controlling the front and rear wheel braking system of a road-going mass-produced motor car or automobile enables provision of brake-by-wire facilities utilising an electrically-powered servo motor (34) to generate brake-operating thrust which is applied to the interleaved friction elements (64, 66, 68) and twin discs (54, 56) of a disc brake (16) having axially slidable discs and a fixed caliper (52) and disc and friction element-attitude control means (70, 72). The brake is of spot-type disc brake construction and the servo motor applies less brake-actuating thrust than is required for a comparable fixed disc and floating caliper construction.
(FR) Cette invention concerne un procédé et un appareil permettant de commander le système de freinage des roues avant et arrière d'une voiture ou automobile circulant sur le réseau routier et construite en série. Grâce à cette invention, on dispose d'installations de freinage à câble utilisant un servomoteur (34) alimenté électriquement, pour générer une poussée d'actionnement de frein appliquée aux éléments de friction intercalés (64, 66, 68) et aux deux disques (54, 56) d'un frein à disques (16), lequel présente des disques à coulissement axial, un étrier de frein fixe (52) et des moyens de commande (70, 72) de l'attitude du disque et de l'élément de friction. Le frein se présente sous forme d'un ensemble frein à disques du type ponctuel et le servomoteur applique une poussée d'actionnement de frein inférieure à celle nécessaire pour un ensemble comparable à disque fixe et étrier de frein flottant.
