Definitions

  • the invention relates to a disc brake, in particular for a commercial vehicle, according to the preamble of claim 1.
  • Such a disc brake is known from DE 43 08 704 Al.
  • the caliper and the receiving space in which the pivot lever having a brake application device is arranged limiting wall integrally formed as a casting.
  • At least one opening is provided in the wall by the machining tools, such as Milling cutter or the like in the receiving space insertable.
  • a lid is provided, which is inserted into the opening.
  • the lid which is usually cup-shaped, is slightly larger in diameter than the clear diameter of the opening in the circumferential jacket region, so that the lid can only be pressed in with a corresponding press-in force.
  • the surface treatment of the caliper it is necessary to lubricate the lateral surface of the lid, which naturally makes the assembly process relatively complicated to facilitate the pressing.
  • the invention is therefore based on the object, so to develop a disc brake of the generic type that it can be produced more economically with simple design.
  • the lid on the one hand and the opening on the other hand self-locking.
  • This self-locking can be done by form and / or friction.
  • the thread of the lid deviates in shape from the female thread of the opening, wherein when screwing the lid a certain deformation of the threads or flanks takes place, which leads to the positive connection.
  • Thread "when screwing the lid, this operation is not different from screwing in a normal thread pairing.
  • the thread profile deforms by the deliberately provided dimensional error so that the screw is clamped.
  • Such a seal in combination with an anti-rotation is also achieved if one or both threaded parts are wetted with a commercial sealant or adhesive, as they are often used to secure screw connections use.
  • the form or frictional engagement can be achieved in that the thread flanks of the outer thread of the lid deviating from the norm, are pointed, so that they deform in the thread root of the nut thread and the connection is clamped.
  • the remaining tolerance fields can be defined according to or deviating from the respective valid standard.
  • At least one of the thread profiles in his Materialei- genschafit be designed so that it can deform easily. Conveniently, the material of the lid is selected accordingly.
  • the changes in the cover thread can be achieved by increasing or decreasing the pitch, increasing the flank diameter, increasing the core diameter or a symmetrical, optionally also asymmetric change in the flank angle and the introduction of a profile notch in the flank.
  • Changes to the nut thread for example, by increasing or decreasing the slope, reduction of the nominal size, reduction of the pitch diameter, reduction of the core diameter or a symmetrical, optionally also asymmetric change in the flank angle.
  • the operating principle of the invention is independent of the material pairing lid / brake caliper, with the most favorable selection is to be determined by experiment.
  • FIG. 1 shows a partial section of a disc brake according to the invention in a plan view
  • FIG. 2 is a detail of an embodiment of the invention
  • Figure 3 shows another embodiment of the invention, also shown as an enlarged partial section in non-functional position
  • Figure 4 shows the detail of Figure 3 in functional position
  • FIG. 1 shows a partial section of a disc brake, in particular for a commercial vehicle shown, comprising a brake disc, not shown
  • Brake caliper 1 on one side of a receiving space 2 for a rotary lever 3 having an application device is arranged.
  • an opening 4 is provided which is closed by a cover 5.
  • the cover 5 is screwed into the opening 4 provided with a female thread 7 (FIG. 2).
  • the thread pairing provided on the outer wall of the cup-shaped lid 5 external thread 6 and the nut thread 7 of the opening 4 is self-locking.
  • the external thread of the lid 5 which is shown in the figure 2 as an enlarged partial section, except initially deviating from the norm, is pointed.
  • this tip deforms as shown in Figure 2, in which this tip rests against one of the flanks of the nut thread 7.
  • the outer diameter of the external thread 6 and the core diameter of the nut thread 7 are chosen so that the flank tips of the external thread 6 overlap before screwing the internal thread 7 in its core diameter.
  • each flank of the external thread 6 is provided with a profile notch 8, which extends approximately radially inward and arise through the double-sided single flanks 9, wherein the height dimension of the flank of the external thread 6 is greater than the associated height dimension of the nut thread. 7
