Definitions
- Disc brake and brake pad for a disc brake in particular for a commercial vehicle
- the invention relates to a disc brake, in particular for a commercial vehicle according to the preamble of claim 1 and a brake pad for a disc brake according to the preamble of claim 8.
- the aim is that maintenance does not take place too early, ie when the wearing parts, ie the brake linings and the brake disk, are still functionally reliable, whereby cost optimization is possible.
- the invention is therefore based on the object, so to develop a disc brake or a brake pad of the generic type that with the least constructive effort a simple, reliable and accurate wear indicator of
- the wear indicator of this new disc brake is characterized first of all by the fact that it can be realized with very little constructive and production-technical effort. This results in a significant cost reduction, which is particularly noteworthy, especially as such disc brake in large numbers produced and used.
- the new wear indicator does not have to be manufactured as a separate part, but is practically integrated in a functionally relevant component, namely in the retaining bracket used to hold the brake linings or indirectly to their bracing.
- this headband is to be regarded as a multifunctional element.
- the marking can be achieved by simple impressions. gene, wherein the mark can be introduced, for example in the form of a bar scale. Manufacturing technology, this is possible in one operation in the shaping of the retaining clip.
- a further advantage is that the new wear indicator achieves a higher display accuracy due to the small or very few manufacturing tolerances that can be maintained, as a result of which the functional reliability of the disc brake is improved overall.
- the new wear indicator can be easily retrofitted, since only the headband needs to be replaced, which can be done for example in the course of a brake pad change.
- the mark on the headband can be modified so that different wear conditions can be seen.
- the scaling is divided accordingly, so that, for example, in a tripartite division of the state of the brake pad as "new", “half", or “consumed” is recognizable.
- the firm, that is accurate positioning of the retaining clip can be done either by a corresponding connection to the caliper, for example in the usual manner by screwing, or, if this is not possible in the desired manner, by a commitment to a pad retaining spring.
- a determination can be made by a positive connection, including the headband has a passage opening into which a projection of the reaction-side pad holding spring engages positively.
- This projection of the pad retaining spring is supported on a tab of the brake pad, which is made by appropriate shaping of a pad carrier plate of the brake pad, which carries a friction lining.
- This tab also protrudes into the passage opening as the projection of the pad retaining spring, which covers the tab area by area. Due to the positive connection between the headband and the lining retaining spring or the brake lining occurring during braking, acting on the brake lining circumferential braking forces are also recorded, which contributes to an overall improvement in overall reliability.
- the headband has a window opening through which the brake pads or their friction linings and the brake disc can be seen, wherein the marking is preferably provided at the edge of this window opening.
- the extending in Leksachsraum the retaining bracket window opening can serve as an end stop for the associated brake pad, is prevented by the fact that the brake pad with appropriate wear of the friction lining from a guide with the caliper in a gap between the brake disc and the caliper, resulting in a significant threat to the reliability of the disc brake.
- Figure 1 shows a part of a disc brake according to the invention in a perspective view
- Figure 2 shows a headband of the disc brake as a detail, also in perspective view.
- Figure 3 shows a part of a brake pad in a perspective view
- a holding bracket shown in Figure 1 which is generally designated by the reference numeral 1, serves to hold down pad retaining springs 10, which act on brake pads 9 and hold them in the shaft of a caliper, not shown, the Part of a disc brake is.
- This brake caliper comprises a likewise not shown brake disc, to which the brake linings 9 can be pressed by means of an application device.
- the fixedly positioned retaining clip 1 is provided with a marking 5 for the optical wear detection of the brake linings 9.
- the retaining clip 1 is held on the brake caliper with one end 2 on the reaction side of the disc brake, that is to say on the application device, for which purpose two legs 3 of the fork-shaped end 2 engage behind an undercut pin of the brake caliper.
- the other end 4 of the retaining clip 1 is held by a securing element 14 on the brake caliper.
- the pad retaining spring 10 is fixed in a conventional manner to a lining carrier plate 12 of the brake lining 9, on which a friction lining 13 is held.
- the projection 11 is designed in its height so that a suspension of the pad spring 10 is possible without the projection 11 slides out of the opening 7.
- a window opening 8 extending in the longitudinal axis direction is provided in the retaining clip 1, by means of which both the friction lining 13 of the assigned brake lining 9 and the brake disk can be seen from the outside
- Window opening 8 is dimensioned so that the brake pad 9 is freely movable in the direction of the brake disc.
- the marking 5, in the exemplary embodiment consisting of a scaling with a total of three scale lines 6 is designed so that the scale lines 6 up to extend the edge of the window opening 8.
- Each scale mark 6 indicates a wear measure, starting from a scale mark 6 indicating "no wear” over a middle scale mark 6 corresponding to "half wear” up to a further outer scale mark 6 as an indication of a "full wear", in reaching a replacement of the brake pad is required.
- the marking 5 can also be represented, for example, merely by a line or an arrow.
- the window opening 8 can also be dispensed with if the marking 5 is guided to the outer edge of the longitudinal edge of the retaining clip 1, so that the wear can be recognized there on the basis of the respective position of the friction linings 13.
- Pad carrier plate 12 a flat protruding tab 15 which is covered in functional position of the projection 11 of the pad retaining spring 10 and the passage opening 7 and the window opening 8 of the retaining clip 1 passes together with the projection 1 1.
- a retaining tab 16 integrally formed on the lining carrier plate 12 to which the pad retaining spring 10 is secured in a form-fitting manner.
