Abstract:
(EN) The invention relates to a main brake cylinder arrangement (10) for a motor vehicle brake system, comprising: at least one piston (44), which can be displaced along a displacement axis (V) and, together with a housing arrangement (12), delimits a pressure chamber; a force input member (19), which is displaceable according to a brake pedal actuation and is coupled or can be coupled to the piston (44) for common displacement; an elongated position encoder element (60), which is displaceable according to an actuation of the force input member (18); a detection unit (66), which is designed to detect a displacement of the position encoder element (60); and a receiving region (64), which is designed to receive the position encoder element (60) at least in sections. According to the invention, the ends (62, 68) of the position encoder element (60) are each arranged in a different housing region (F, S), which is arranged in a fluid path between the first and second housing region (F, S).
(FR) L'invention concerne un ensemble maître-cylindre de frein (10) pour un système de freinage de véhicule. L'ensemble comprend : - au moins un piston (44), qui peut se déplacer le long d'un axe de déplacement (V) et qui délimite conjointement avec un ensemble carter (12) une chambre de pression ; - un organe d'entrée de force (19), qui est déplaçable en fonction de l'actionnement de la pédale de frein, et est accouplé ou peut être accouplé au piston (44) aux fins d'un déplacement commun ; - un élément indicateur de position (60) allongé, qui est déplaçable en fonction de l'actionnement de l'organe d'entrée de force (18) ; - une unité de détection (66), qui est conçue pour détecter un déplacement de l'élément indicateur de position (60) ; et - une zone de réception (64), qui est conçue pour recevoir au moins en partie l'élément indicateur de position (60). Les extrémités (62, 68) de l'élément indicateur de position (60) sont agencées dans différentes zones (F, S) du carter, et sont agencées dans un trajet de fluide entre la première et la deuxième zone (F, S) du carter.
(DE) Die Offenbarung betrifft eine Hauptbremszylinderanordnung (10) für eine Kraftfahrzeugbremsanlage, umfassend: - wenigstens einen Kolben (44), der entlang einer Verlagerungsachse (V) verlagerbar ist und gemeinsam mit einer Gehäuseanordnung (12) eine Druckkammer begrenzt; - einem Krafteingangsglied (19), das nach Maßgabe einer Bremspedalbetätigung verlagerbar und mit dem Kolben (44) für eine gemeinsame Verlagerung gekoppelt oder koppelbar ist; - ein langgestrecktes Positionsgeberelement (60), das nach Maßgabe einer Betätigung des Krafteingangsgliedes (18) verlagerbar ist; - eine Erfassungseinheit (66), die dazu ausgebildet ist, eine Verlagerung des Positionsgeberelements (60) zu erfassen; und - einen Aufnahmebereich (64), der dazu ausgebildet ist, das Positionsgebereiement (60) zumindest abschnittsweise aufzunehmen. Dabei sind die Enden (62, 68) des Positionsgeberelements (60) in verschiedenen Gehäusebereich (F, S) angeordnet, die in einem Fluidpfad zwischen dem ersten und zweiten Gehäusebereich (F, S) angeordnet ist.
