Definitions

  • the invention relates to a brake system having a rotary element rotatable about a rotation axis and a braking device for braking the rotary element, wherein the braking device has a first brake element which is disposed between a rest position in which an annular braking surface of the first brake element concentric with the axis of rotation of Rotary element and is arranged remote from the rotary member, is movable in a braking position, in which the braking surface of the first Bremsele- element in abutment with the rotary member or with a rotatably connected to the rotary member second brake element.
  • a trained as a skateboard low-floor vehicle is known for example from US 6,659,480 B1.
  • this skateboard has an axle carrier unit with two wheels on which a brake device for braking the wheels is arranged.
  • Each wheel is assigned a brake element which has a ring-shaped braking surface, which is arranged in a rest position of the brake element remote from the respective wheel.
  • the brake element can be moved into a braking position by means of a pivotable lever, in which the brake element rests against a further brake element that is non-rotatably connected to the respective wheel.
  • the pivotable lever acts on the first brake element, primarily in a region above the axis of rotation of the wheel with a force. When braking forces are therefore applied to the wheel, which load the wheel bearings asymmetrically and can lead to premature failure of the wheel bearings. This will affect the life of the vehicle.
  • the first brake pad is preferably releasably connected to the first brake element, so that replacement of a worn brake pad is possible.
  • the first brake pad is positively connected to the first brake element.
  • the first brake pad of the first brake element is annular or cylindrical, so that the annular braking surface occupies as completely as possible.
  • a first brake pad is disposed on the first brake element and on the second brake element no brake pad is arranged.
  • the first brake pad of the first brake element is formed segmented.
  • the first brake pad may be segmented such that it includes one or more ring segments.
  • the second brake lining is preferably releasably connected to the second brake element, so that replacement of a worn brake lining is possible.
  • the second brake pad is preferably positively connected to the second brake element.
  • the first brake element comprises a plurality of ventilation holes.
  • the ventilation holes are formed with different cross section.
  • a first ventilation bore which is arranged closer to the axis of rotation, has a larger cross-sectional area than a second ventilation bore, which is arranged further away from the axis of rotation.
  • FIG. 6 shows a further exemplary embodiment of an axle carrier unit with a brake system according to the invention in a sectional representation through a rotary element, the sectional plane containing the axis of rotation of the rotary element;
  • FIGS. 6 and 7 show a further exemplary embodiment of a brake system 30.
  • the brake system 30 according to FIG. 6 can be provided as part of an axle carrier unit 4 which is used, for example, as a rear axle in the low-floor vehicle 1 according to FIG can. Alternatively or additionally, such an axle support unit 4 can be used as the front axle of the vehicle 1.

Abstract

L'invention concerne un système de freinage (30) comportant un élément rotatif (5) pouvant tourner autour d'un axe de rotation (D) et un dispositif de freinage (10) pour freiner l'élément rotatif (5), ledit dispositif de freinage (10) présentant un premier élément de freinage (13) qui peut se déplacer entre une position de repos, dans laquelle une surface de freinage (14) annulaire du premier élément de freinage (13) est concentrique à l'axe de rotation (D) de l'élément rotatif (5) et est montée à distance de l'élément rotatif (5), et une position de freinage, dans laquelle la surface de freinage (14) du premier élément de freinage (13) est en appui avec l'élément rotatif (5) ou avec un second élément de freinage (9) relié solidaire en rotation avec l'élément rotatif (5), le premier élément de freinage (13) pouvant se déplacer de manière hydraulique entre la position de repos et la position de freinage, le premier élément de freinage (13) étant relié à un piston de frein (12) cylindrique creux qui présente un espace intérieur cylindrique creux destiné à recevoir un liquide hydraulique, le premier élément de freinage (13) étant conçu annulaire et présente sur un contour intérieur de premiers éléments à complémentarité de forme (24), en particulier plusieurs dents ou des clavettes qui coopèrent avec de seconds éléments à complémentarité de forme (23) correspondants sur un contour extérieur du carter (11), de sorte que le premier élément de freinage (13) est sécurisé pour éviter une rotation autour de l'axe rotation (D) et peut se déplacer parallèlement à l'axe de rotation (D). L'invention concerne en outre un ensemble support d'essieu (4) pour un véhicule à plancher surbaissé, en particulier une planche à roulettes, comportant un système de freinage (30) selon une des revendications précédentes, l'élément de rotation (5) du système de freinage se présentant sous forme de roue, ainsi qu'un véhicule à plancher surbaissé (1) muni d'un tel ensemble support d'essieu (4). L'invention concerne également une unité d'entraînement munie d'un tel système de freinage (30).
