Title
(DE) HYDRAULIKZYLINDERANORDNUNG FÜR FAHRZEUG-SCHEIBENBREMSE

Abstract
(DE)
Eine Scheibenbremse für Fahrzeuge umfasst in bekannter Weise ein Bremssattelgehäuse (1), welches eine Bremsscheibe (3) überspannt. In einer Zylinderbohrung (9) des Bremssattelgehäuses (1) ist in bekanner Weise ein Bremskolben (2) verschiebbar gelagert. Als Rückführeinrichtung für den Bremskolben (2) dient ein elastisch verformbarer Ring (7), der sowohl in eine Ringnut (5) des Bremskolbens (2) als auch in eine Ringnut (6) in der Wand der Zylinderbohrung (9) eingreift. Der elastisch verformbare Ring (7) wird in einer (6) der beiden Nuten (5, 6), die axial kürzer als die andere ist, in axialer Richtung festgehalten und bei der Bewegung der jeweils anderen Nut (5) in definierter Weise elastisch verformt, was eine definierte Rückstellkraft zur Folge hat. Bei optimaler Auslegung der verschiedenen Parameter lässt sich auf diese Weise eine ABS-ähnliche Bremswirkung erzielen, ohne hierfür eine elektronische Steuerung zu benötigen.
(EN)
The invention relates to a vehicle disk brake comprising, in the known manner, a brake caliper housing (1) which spans a brake disk (3). In a cylindrical bore (9) of the brake caliper housing (1) a sliding brake piston (2) is mounted in the known manner. As return device for the brake piston (2) an elastically deformable ring (7) is provided for which engages both a ring groove (5) of the brake piston (2) and a ring groove (6) in the wall of the cylindrical bore (9). The elastically deformable ring (7) is held in the axial direction in one (6) of the two grooves (5, 6) which is axially shorter than the other. During a movement of the corresponding other groove (5) the ring is elastically deformed in a defined manner, which generates a defined restoring force. By optimal adjustment of the different parameters an ABS-like braking action can be obtained without the need for an electronic control.
(FR)
Un frein a disque pour véhicules comprend, de façon connue, un carter d'étrier de frein (1) qui chevauche un disque de frein (3). Dans un alésage cylindrique (9) du carter d'étrier de frein (1), un piston de frein (2) et monté coulissant de façon connue. Une bague (7) élastiquement déformable sert de dispositif de rappel pour le piston de frein (2). Cette bague s'engage aussi bien dans une rainure annulaire (5) du piston de frein (2) que dans une rainure annulaire (6) ménagée dans la paroi de l'alésage cylindrique (9). Ladite bague (7) élastiquement déformable est maintenue dans le sens axial dans une (6) des deux rainures (5, 6) qui est axialement plus courte que l'autre, la bague étant élastiquement déformée de façon définie lors du déplacement de l'autre rainure (5), ce qui crée une force de rappel définie. Avec une sélection optimale des différents paramètres, on peut obtenir un effet de freinage semblable à celui obtenu avec un système anti-blocage, sans qu'il soit nécessaire de recourir à une commande électronique.
