Definitions

  • the invention relates to a brake device according to the preamble of claim 1.
  • a disc brake is attached to a wheel axle, preferably a utility vehicle.
  • the disc brake on a mounting body of a caliper or brake carrier, which is connected to a rigidly attached to the wheel axle connecting part.
  • connection between the fastening body and the connecting part in which the fastening body is connected to the connecting part via screws extending axially parallel to the wheel axis, wherein the fastening body bears against flange surfaces of the connecting body.
  • flange surfaces are referred to as in-line and out-going oriented flange flats, with the incoming-oriented ones being considered to be the first and the outwardly-oriented flanges in the direction of rotation of a turntable.
  • the outwardly oriented flange surface is subjected to a significantly higher load than the initially oriented one.
  • the screw connection between the fastening body and the connecting part is dimensioned so that the forces to be transmitted via a can be transmitted by the screw connection formed frictional engagement, wherein the frictional engagement is achieved by pressing the fastening body to the flange surfaces of the connection part.
  • the screw connections each consist of a through-hole, a threaded hole and a screw, wherein the through-hole can be provided in the connection part or fastening body and the threaded hole is assigned in the other
  • the diameter of the through hole must be larger than the shaft diameter of the screw.
  • the space-related under-dimensioning of the screws and the associated only limited frictional engagement between the connecting part and the fastening body there is a relative movement of the through-hole member having respect to the other until the reveal of the through hole comes to rest on the screw shank.
  • the screws are subjected to considerable wear on shears.
  • This relative movement between the fastening body and the connecting part can result in a component of the brake being subjected to a great deal of high deformation and resulting in damage, for example cracking.
  • dowel screw is used for lateral force transmission, but only one due to manufacturing tolerances.
  • the dowel screw is used on this surface, so that a power transmission during braking in the forward direction without Relatiwerschiebung is possible.
  • the dowel screw is not effective because here support the brake pads on the other side of the mounting body.
  • At high braking torque in the reverse direction can therefore on the flange without a dowel screw said relative displacements between the connector and the mounting body occur with the described consequences, namely high component stresses and resulting cracking.
  • the invention has for its object to further develop a braking device of the generic type so that their design with little effort
  • the friction-increasing coating can be applied directly to the flange surfaces. It is also conceivable, however, to arrange between the flange surfaces and the associated contact surfaces of the fastening body provided with a coating carrier elements, for example made of sheet metal, these two-dimensional support elements are coated on both sides. Since there are no form-fitting elements, as are also known from the prior art for the transmission of braking torque, the components which are merely screwed together can be assembled or disassembled without difficulty. Moreover, this results in cost advantages that no tolerances are to be complied with, as is required in the above-mentioned positive locking.
  • thermal metal spraying has been shown, for example, the so-called arc coating.
  • metal wire is melted in the arc and sprayed by pressure on the surface to be coated.
  • other candidate coating methods such as flame coating, plasma coatings or the like.
  • the spray coating by means of a spray wire with a
  • ceramics or minerals can also be used as coating material.
  • Figure 1 shows a part of a braking device according to the invention in a front view
  • FIG. 2 shows another embodiment of a braking device in a side view
  • a braking device which has a fastened to a wheel axle of a motor vehicle, in particular a commercial vehicle connector part 1, which has two flange 2, which extend in a cross-sectional plane of the wheel axle.
  • a brake caliper 7 is firmly provided, which engages over a brake disc 4 connected to the wheel axle against rotation and to which a fastening body 3 is connected, which is connected by means of screws 5 fixed to the connector part 1.
  • the fastening body 3 which is not shown in FIG. 1, rests on the flange surfaces 2 in these exemplary embodiments, into which threaded bores 5 are made, into which the screws 9 which pass through the fastening body are screwed.
  • the flange 2 are fiction, provided with a coefficient of friction increasing coating 6, which is applied for example by thermal metal spraying.
  • the coating 6 is applied on both sides to a carrier element 8 in the form of a sheet, which bears against the flange surfaces 2 of the attachment part 1 on the flange surfaces 2 on the one hand and on the attachment body 3 on the other hand in the overlapping area of the attachment body 3.
  • This embodiment variant offers special advantages over a direct coating of the flange surfaces 2, in that the connecting part 2 or the fastening body 3 are not thermally stressed, as is the case with thermal metal spraying.
  • such a carrier element 8 can be produced particularly simply and inexpensively as an individual part.
  • either the flange surfaces 2 or the associated contact surfaces of the fastening body 3 can be correspondingly coated. It is also conceivable, however, to coat both adjoining surfaces in order to increase the friction value if necessary.

Abstract

L'invention concerne un dispositif de freinage présentant une pièce de raccordement (1), fixée sur un essieu d'un véhicule automobile et pourvue de faces de bride (2), ainsi qu'un corps de fixation (3) d'un étrier de frein (7) ou d'un support de frein d'un frein à disque, lequel corps est relié à la pièce de raccordement et appliqué contre cette dernière par liaison de frottement. Ce dispositif de freinage est conçu, de sorte qu'un revêtement (6), augmentant les coefficients de frottement, est prévu dans les zones de contact communes entre la pièce de raccordement (1) et le corps de fixation (3).
