Definitions

  • the invention relates to a disc brake, in particular for a utility vehicle, according to the preamble of claim 1.
  • the headband of such a disc brake mainly serves as an abutment for springs, in the known disc brake leaf springs, which clamp the brake shoes resiliently.
  • the retaining clip is releasably attached to the caliper, so that both a quick assembly and disassembly of the brake shoes is possible. This, for example, to allow easy access for a brake pad change access to the brake shoes.
  • the pocket-shaped receptacle is provided on the side of the brake caliper forming the brake outer side, which lies opposite a brake-caliper application device which forms the inner side of the brake, that is, the side facing the center of the vehicle.
  • the recording can be adjusted by mechanical processing. be brought in or at the manufacture of the caliper by casting equal with molded.
  • the retaining bracket with its other end facing the application device is bolted to the brake caliper.
  • this requires a correspondingly complex processing, i. a drilling of the core hole and a subsequent thread cutting. Since such disc brakes are produced in large numbers, these operations are contrary to an optimized production, so that the product can be produced in total only with a correspondingly high cost.
  • connection pin / washer and sapwood requires a corresponding space, which can only be produced with considerable effort due to the prevailing tight space conditions.
  • the invention has for its object to further develop a disc brake of the generic type so that it is cheaper to produce and a simpler and faster assembly and disassembly of the brake shoes is possible. This object is achieved by a disc brake with the features of claim 1.
  • the holes in which the two separate and preferably parallel to each other legs of the fastener extend in L jossachscardi of the retaining clip. This allows a particularly simple and cost-effective processing of the holes, since the machining direction corresponds to the main machining direction, so that no further clamping of the caliper is required.
  • a preferred embodiment of the fastening means is in the form of a W-shaped, two-legged mounting bracket, whose center region is supported as a support leg on the headband, while the two legs extend relative to this support leg in a lower level.
  • the fixation tion of the retaining clip thus takes place exclusively by the system of the mounting bracket, which is shaped so that it rests under a certain pressure on the headband.
  • a special processing of the retaining clip in the sense of introducing holes or receptacles for receiving the fastener is no longer required by the invention, which also contributes to cost optimization.
  • By now possible waiver of openings in the headband this is not only easier to produce, but also achieves a higher rigidity.
  • the same holding brackets and fasteners can be used for differently configured disc brakes, which results in a reduction of the storage costs, but also the manufacturing cost itself.
  • the mounting bracket inherent restoring forces through which the mounting bracket rests on the headband under pressure, cause a clearance between the brake shoes and the headband is reduced, so that the sensitivity to vibration loads is minimized.
  • the contact point of the mounting bracket so the support leg on the headband is in a plane with two sockets, which accommodate the holes for receiving the leg. This avoids the occurrence of a bending moment that would add weight to the sockets. It is therefore possible to produce the base with a low cost of materials.
  • FIG. 1 shows a partial section of a disc brake according to the invention in a front view
  • FIG. 2 shows a partial section of a disk brake in plan view
  • Figures 3 and 4 each show a detail of the disc brake in a perspective view
  • FIG. 5 shows a partial section of the disc brake, likewise in a perspective view
  • FIGS. 1, 2 and 5 show a disc brake, in particular for a commercial vehicle, with a brake caliper 1 having a receiving space 15 for a brake application device, not shown, which has a brake disc 2 'which can be brought into operative connection with brake shoes 2 a brake carrier is fastened.
  • a retaining clip 4 is releasably secured, on which are supported on the rougekaten the brake shoes 2 acting springs 3 in the form of leaf springs.
  • the headband 4 is positively held with one end in a pocket-shaped receptacle 8 on the side opposite the receiving space 15 side of the caliper 1, while the other end is connected via a fastener 5 to the caliper 1.
  • this fastening element 5 has two legs 10, which run away from one another in a positionally fixed manner and which are in a positionally secured manner in holes 7 provided on both sides next to the retaining bracket 4 in the brake caliper 1.
  • the fastening element is W-shaped and, in addition to the mutually parallel two legs 10 has a central support leg 9, which is supported on the headband 4.
  • the legs 10 extend below the support leg 9, wherein the holes 7, in which the legs 10 are inserted, eino in sockets 6 of the caliper 1.
  • These pedestals 6 are expediently formed during casting of the caliper 1 with.
  • the holes 7 and thus the legs 10 extend in the axial direction of the brake disc 2 '.
  • the legs 10 of the fastener 5 are inserted on both sides by the base 6 and secured at the ends by a pin 12, which is guided through a bore 11 of the associated leg 10 with a pin 13, while on both sides the pins 13 adjoining clips 14 on the outside of the leg 10 ( Figures 3 and 4).
  • a leg 10 of the fastener 5 is felt through a base 6 and there axially secured by means of a locking plate 17 which is positively locked in a groove 16 of the leg 10.
  • the other leg 10 is made longer and inserted only in the associated base 6, wherein the unilateral securing of the other leg 10 by means of the securing plate 17 is sufficient by the longer guide of the leg 10.
  • the support leg 9 rests in a plane 18, transverse to the central axis of the brake disc 2 ⁇ with the sockets 6, whereby a bending moment is avoided, by which the base 6 would be charged.
  • the base 6 can therefore be produced with low material usage.
  • Standard parts can be used as securing elements in the form of the split pin 12 or the securing plate 17, wherein the selection is not limited to these two variants. Rather, other known security elements are quite applicable.

Abstract

L'invention concerne un frein à disque, conçu en particulier pour un véhicule automobile, comprenant : un étrier de frein (1) qui comporte un espace de réception (15) prévu pour un dispositif d'application de frein, ainsi qu'un disque de freinage (2') pouvant coopérer avec des mâchoires de frein (2), et qui est fixé sur une flasque de frein, et ; un étrier de retenue (4) qui est fixé de manière libérable sur l'étrier de frein (1), et contre lequel reposent des ressorts (3) qui agissent sur l'arête extérieure des mâchoires de frein (2). Selon l'invention, une extrémité de l'étrier de retenue (4) est insérée dans un logement (8) de l'étrier de frein par liaison de forme, tandis que l'autre extrémité est maintenue au moyen d'un élément de fixation (5). Le frein à disque selon l'invention est caractérisé en ce que cet élément de fixation (5) comprend deux branches (10) qui s'étendent à une distance l'une de l'autre, et qui sont insérées et bloquées dans deux orifices (7) adjacents ménagés dans l'étrier de frein, à côté de l'étrier de retenue (4).
