  • WO 00/42332 AI describes, for example, a brake disk arrangement of a motor vehicle disk brake with an axially fixed support, on which two friction rings are arranged so as to be non-rotatable in the circumferential direction and to be displaceable in the axial direction.
  • the carrier together with the friction rings, is coupled to a rotational movement of a vehicle axle.
  • the friction rings interact tribologically with the associated brake pads of a corresponding motor vehicle disc brake.
  • the brake linings are mounted on a brake caliper of the motor vehicle disc brake so as to be displaceable in the axial direction.
  • the friction package consisting of friction rings and brake linings is compressed to achieve the tribological braking effect.
  • Both the brake pads and the friction rings pass through an axial displacement path.
  • the occurrence of corrosion and dirt on the friction ring guides can impair the entire braking function.

  • a toothing is formed between the friction rings and the carrier, which is effective as a guide device.

  • the type and number of guide bolts used can sufficiently take into account the circumferential load that is present depending on the application.
  • An advantageous variant of the brake disc arrangement is achieved in that the guide pin is surrounded by a protector element which seals the guide pin from the environment. This ensures a permanently smooth friction ring guide. Relatively small protector elements are sufficient, each of which only surrounds the guide pin and does not shield the entire circumference of the carrier.
  • the protector element is preferably arranged between two friction rings, so that the penetration of moisture and dirt into the friction ring or bolt guide is prevented. In this way, the friction ring guide is spared from corrosion and dirt.
  • the protector element is sensibly designed as a bellows.
  • the bellows can advantageously consist either of plastic, in particular a rubber material, or of a metallic material.
  • the protector element it is also conceivable to design the protector element as a flexible fabric element, for example as a steel flex hose. Such fabric elements have a higher thermal load capacity.
  • the carrier can be designed as a wheel hub.
  • the wheel hub is non-rotatably connected to the corresponding axle in the case of driven axles or rotatably mounted on the axle in the case of non-driven axles.
  • the friction rings are thus arranged directly on the wheel hub, saving additional components. Circumferential braking forces occurring on the friction rings can thus be dissipated directly via the wheel hub.
  • the carrier preferably comprises two flanges, between which at least one displaceable friction ring is arranged.
  • the guide bolts are preferably screwed to the first axle-side flange, which simplifies the releasability of the guide bolts from the wheel side or the vehicle outside.
  • at least the wheel flange is designed in such a way that friction ring assembly and disassembly is also possible from the outside of the vehicle.
  • the variants of the brake disc arrangement described can interact with an associated fest as well as with a floating caliper disc brake.
  • Fig.l shows a brake disc assembly with two friction rings slidably guided by guide pins in a sectional view

Abstract

La présente invention concerne un ensemble de disque de frein (1) pour un véhicule présentant au moins un essieu. Cet ensemble de disque de frein (1) comprend un support (3) monté sur l'essieu du véhicule, qui présente plusieurs anneaux de friction (2) reliés bloqués en rotation en direction de la périphérie au support (3). Au moins un de ces anneaux de friction peut être guidé sur le support (3) de manière à se déplacer en direction axiale. Afin d'améliorer et de simplifier le guidage des anneaux de friction, au moins un boulon de guidage (7) est attaché de manière amovible sur le support (3). Ce boulon de guidage traverse au moins un anneau de friction (2) en direction axiale afin d'installer celui-ci mobile sur le support (3). Le guidage des anneaux de friction se voit ainsi transformé de manière flexible et économique au moyen de boulons de guidage (7) et ce, avec une bonne qualité de guidage.
