Definitions

  • the present invention relates to a drum brake pot and a Verfah
  • Drum brakes are friction brakes in which brake pads act on a cylindrical surface, the brake drum.
  • the brake drum is a round, substantially closed metal body fixedly attached to the wheel hub of cars or motorcycles.
  • the brake pad When the brake is actuated, the brake pad is usually pressed from the inside against the revolving brake drum and thus kinetic energy is converted into heat. The resulting heat is absorbed by the brake drum and indicated by cooling fins to the air.
  • the usual brake drums are usually cast from gray iron or iron, since high strength, stiffness and heat conduction is required due to the high forces occurring during braking.
  • DE 10 2011 054 484 AI shows a brake drum for vehicles with a substantially cup-shaped body, which is cast from a light metal.
  • the friction body is attached to a radial inner surface of the body and made by casting or forging, for example, from a steel.
  • the present invention is based on a drum brake pot with a substantially cylindrically shaped housing and a friction element arranged inside the housing.
  • the essence of the invention is that the housing consists at least partially of sheet metal.
  • the sheet is a metal sheet. This can be a sheet steel.
  • the sheet is a
  • Light metal sheet in particular an aluminum sheet.
  • the friction element may be designed substantially annular and consists in a particularly advantageous embodiment of the invention of gray cast iron.
  • the housing has a first profile on the housing inner surface facing the friction element.
  • the friction element has on the side facing the housing inner surface friction element outer surface has a second profile, wherein the first and second profile are configured such that the profiles intermesh. As a result, a very good stability and a very good connection between the housing and friction element is realized.
  • the housing has at least one stop on the housing inner surface facing the friction element, by means of which the axial displacement of the friction element in the housing is limited.
  • the friction element can thereby be pressed against the stop during assembly.
  • the axial position of the friction element in the housing can be generated by caulking.
  • the friction element can be glued to the housing and / or connected soldered. It can be provided that the bond and / or soldering connects the housing inner surface facing the friction element and the belt outer surface facing the housing inner surface.
  • the invention is also a method for producing a drum brake pot with the following steps:
  • the axial insertion of the friction element into the housing occurs up to at least one stop attached to the housing inner surface facing the friction element.
  • the axial insertion of the friction element in the housing can be done in such a way that the housing inner surface, which faces the friction element in the inserted state, interacts with the friction element outer surface facing the housing inner surface in the inserted state
  • FIG. 1 shows schematically the housing of the drum brake while Figures 2 and 3 depict a perspective view of an embodiment of the invention with a profiled housing.
  • FIG. 4 shows a schematic representation of an alternative embodiment of the invention with a non-profiled housing.
  • FIG. 1 shows the reference numeral 101, the substantially cylindrical housing with a profiled shape.
  • FIG. 2 shows the housing 201 with a profiled shape.
  • the reference numeral 202 denotes the friction element with a friction element outer surface 204 facing the inside surface 203 of the housing.
  • FIG. 3 A more detailed illustration of the embodiment with the profiled housing is shown in FIG.
  • the friction element 302 can be glued to the housing 301 and / or connected soldered.
  • the axial position of the friction element 301 is limited by the stops 301.
  • FIG 3 an alternative embodiment of the invention is shown in which the housing 301 has no profiled shape.
  • the brake drum in this embodiment has a predominantly smooth shape on the sheet pot 301, which can be produced by deep drawing with standard presses, pressures or comparable.
  • the cast iron friction ring 302 is pressed against a stop during assembly.
  • the axia The layer is secured at locations 401 by gluing, soldering or the like of the friction ring 302 in the sheet-metal shell 301.

Abstract

L'invention concerne un bol de frein à tambour comprenant un carter (201) sensiblement cylindrique et un élément de friction (202) agencé à l'intérieur du carter. Le carter est constitué au moins en partie de tôle. L'utilisation de tôle dans la zone des tambours de frein permet de réduire le poids, et peut être mise en place lors de la fabrication de tous les freins à tambour comme solution de construction légère pour les tambours de frein installés.
