Title
(DE) BREMSGERÄT FÜR EINE HYDRAULISCHE KRAFTFAHRZEUGBREMSANLAGE
(EN) BRAKE DEVICE FOR VEHICLE HYDRAULIC BRAKE SYSTEM
(FR) DISPOSITIF DE FREIN POUR SYSTÈME DE FREINAGE HYDRAULIQUE D'UN VEHICULE
Abstract
(DE)
Es wird ein verbessertes Bremsgerät (1) mit einer hydraulischen Verstärkerstufe (2) für eine hydraulische Kraftfahrzeugbremsanlage, das innerhalb eines regulären Verstärkungsbetriebs sowohl in einem autonomen fahrerunabhängigen Betätigungsmodus elektronisch gesteuert als auch in einem manuellen Betätigungsmodus durch den Fahrer gesteuert und außerhalb des regulären Verstärkungsbetriebs in einem Notfallmodus mit einer alleine durch den Fahrer erzeugten unverstärkten Betätigungskraft betrieben werden kann, angeboten, bei dem erfindungsgemäß vorgeschlagen wird, dass innerhalb des regulären Verstärkungsbetriebs jedem Betätigungsmodus eigens ein gesonderterKolben (9,13) in einem Verstärkergehäuse (3) der Verstärkerstufe (2) zugeordnet ist, der unmittelbar mit der Verstärkungskraft beaufschlagt wird und diese mechanisch an wirkungsmäßig nachgeschalteten Komponenten vermittelt.

(EN)
An improved brake device (1) having a hydraulic booster stage (2) for a hydraulic motor vehicle brake system is provided, which brake device, within normal boosting operation, can be operated both in an autonomous, driver-independent actuation mode with electronic control and in a manual actuation mode controlled by the driver, and outside normal boosting operation, can be operated in an emergency mode with a non-boosted actuation force generated by the driver alone, in the case of which brake device it is proposed according to the invention that, within normal boosting operation, each actuation mode is assigned a dedicated piston (9, 13) in a booster housing (3) of the booster stage (2), which piston is acted on directly with the boosting force and transmits this mechanically to components connected functionally downstream.

(FR)
L’invention concerne un dispositif de freinage (1) amélioré comprenant un étage d’amplification hydraulique (2) pour un système de freinage hydraulique de véhicule à moteur. Dans le cadre d’un mode d'amplification normal, le dispositif de freinage peut être commandé aussi bien électroniquement dans un mode d'actionnement autonome, indépendant du conducteur, que par le conducteur dans un mode d'actionnement manuel et, en dehors de ce cadre, ledit dispositif peut fonctionner dans un mode de détresse avec une force d'actionnement non amplifiée générée par le conducteur uniquement. Selon l’invention, dans le cadre du mode d'amplification normal, un piston séparé (9, 13) est associé spécialement à chaque mode d'actionnement dans un carter de servofrein (3) de l'étage d'amplification (2), ledit piston étant directement soumis à la force d’amplification et transmettant cette force par voie mécanique à des éléments montés en aval en liaison fonctionnelle.
