Definitions

  • the present invention relates to a disc brake for a commercial vehicle according to the preamble of claim 1.
  • Such a disk brake is known for example from DE 103 00 013 Al.
  • Adjustment provided by means of a clearance between the brake disc and brake shoes is adjustable.
  • the adjustment means or a synchronization is e.g. operated via a synchronous transmission and has for this purpose an output gear, which is driven mechanically or via an electric motor. Both the output gear and the
  • Electric motor are arranged inside or outside the caliper, as well as other functional parts that are required for the operation of the disc brake.
  • the lid is connected to the caliper.
  • the invention is therefore based on the object to further develop a disc brake of the generic type, that the lid for the encapsulation of functional parts is secured tamper-proof and a more cost-effective production and assembly is possible.
  • Lids are largely dispensed with, since connection connections, such as threaded holes or the like are no longer required. Such a renunciation of preparatory work leads, for obvious reasons, to a reduction in manufacturing costs, resulting in significant savings.
  • the welding can be done by laser or welding electrodes.
  • Laser welding are in the contact area of the lid with the caliper a plurality of openings, preferably provided in the form of holes, on the inner edge of a circumferential laser weld is generated, through which the welded joint is produced.
  • the cover When welding by means of a welding electrode, the cover rests with pronounced welding pins on the caliper, while the welding electrodes are immersed in a concentric blind hole, which is followed by the welding pin. The welding takes place inductively. It is also conceivable that the caliper is provided with welding pin.
  • the welding pins can be introduced by impressing, while in the case of a plastic lid, the respective welding pin is part of an inserted metal ring, which rests at least axially secured in the plastic lid.
  • the plastic cover introduced metal rings are also the connection by means of laser welding, in which case the metal ring is modified accordingly. Both welding methods can be automated, that is, by a suitable robot can be carried out in a very efficient way, an automatic welding of the lid to the caliper.
  • FIG. 1 shows a cover of a disc brake according to the invention in a perspective view
  • FIGS. 2 and 3 3 each embodiment of a detail of the lid of Figure 1
  • Figures 4 to 6 are each a partial cross-section through a detail of the connectable to a caliper cover
  • a cover 1 is shown, which is integrally connected to an indicated caliper 2 ( Figure 4) a disc brake for a commercial vehicle, wherein the cover 1 outside the caliper 2 arranged, not shown functional parts of an adjusting device, such as transmission parts in terms of Encapsulation covered.
  • the lid 1 shown in Figure 1 is made of plastic and has in the edge region of its outer contour a plurality of inserted metal rings 3 or 4, of which an embodiment is shown enlarged in Figures 2 and 3.
  • the metal rings 3, 4 axially secured, preferably also secured against rotation, mounted in the cover 1, to which on the metal ring 3, a circumferential bead 6 is integrally formed, which corresponds positively to the lid 1.
  • the metal ring 3 is configured to be weldable to the caliper 2 by means of an electrode 11 (FIG. 5).
  • the metal ring 3 on its caliper 2 facing the end of a central pin 5, which melts when immersing the electrode 11 in a blind hole 12 of the metal ring 3 and applying power and welded to the caliper 2, which also consists of metal welded , Excess weld material of the pin 5 is received by a concentric undercut 7 which is adjacent to the pin 5.
  • the lid 1 is made of metal.
  • the pin 5 is formed here by corresponding impressing the lid 1, below
  • the cross section of the pin 5 is kept relatively small, while the outer diameter of the formed as a rotationally symmetrical body
  • Metal ring 3 is chosen to be relatively large, so that it heats only slightly during welding.
  • Lid 1 is mounted in plastic.
  • This metal ring 4 is provided with a through hole 8 and has on its the caliper 2 facing end face a support ring 9, with which it is supported on the caliper 2.
  • a seal 13 is provided for sealing the functional parts receiving the interior of the lid 1 relative to the surrounding environment, which is sealingly supported on the one hand on the cover 1 and on the other hand on the brake caliper 2.

Abstract

L'invention concerne un frein à disque conçu pour un véhicule utilitaire. Ce frein à disque comprend un étrier de frein qui recouvre un disque de frein, ainsi que des pièces fonctionnelles qui sont disposées en-dehors de l'étrier de frein, telles que les pièces d'entraînement d'un dispositif de réajustage qui sont emboîtées à l'aide d'un couvercle (1) lequel est fixé sur le côté extérieur de l'étrier de frein. Le frein à disque selon l'invention est configuré de manière que le couvercle (1) soit relié avec l'étrier de frein par liaison de matière.
