Definitions
- the invention relates to a disc brake for a commercial vehicle according to the preamble of claim 1 and a brake pad for a disc brake.
- This caking usually leads to increased wear of the brake pads and the brake disc, but also to an elevated temperature in the non-braked position, since the so far stiff brake pads practically permanently applied to the brake disc and generate a residual torque.
- the assembly of the brake pads is carried out initially by insertion through the mounting hole of the caliper in the brake carrier and then, based on the brake disc, axial insertion into the respective lining shaft, with a corresponding stop of the brake carrier recess of the brake pad must be in coverage.
- the problem here is that in the coverage area, the spring, usually a leaf spring, must be deformed to bias the brake pad against the brake carrier in order to introduce the brake pad and to achieve the bias of the spring.
- the invention has for its object to further develop a disc brake of the generic type so that the assembly of the brake pads simplifies and the operating costs are reduced.
- This object is achieved by a disc brake with the features of claim 1 and by a brake pad having the features of claim 10.
- the inventive design of the basic concept of the invention is realized to allow the tension of the brake pad with the brake carrier only after the assembly of the brake pad. In this case, the brake pad can be mounted virtually force-free in the lining shaft.
- the invention can be implemented in a disc brake in which the brake carrier has only one lining shaft for receiving a brake lining, namely the application side, while the reaction-side brake lining is held on the brake caliper, for example.
- the disc brake according to the invention equipped with a brake carrier with two lining shafts, for brake pads, one of which is associated with one side of the brake disc, wherein the brake disc, which is pneumatically or electromechanically actuated, can be designed as Schiebesattel- disc brake.
- a pad retaining spring is arranged on the pad carrier plate for radially resilient locking or pretensioning of the brake pad, which is engaged by a dimensionally stable clamping element as an abutment Brake caliper is held locked.
- the tensioning element which practically forms a suspension for the brake lining, is designed as a specially configured pad retaining strap, which is pushed under the pad retaining spring after insertion of the brake pad and pulls it and thus the brake lining against the stops of the brake carrier in the lining slot, forming a game opposite the brake carrier.
- this has an insertion bevel so as to be able to push the pad retaining clip more easily under the pad retaining spring.
- the pad retaining spring is preferably designed as a leaf spring and extends in the longitudinal direction at least in a partial area along the edge of the lining carrier plate facing the mounting opening, which is usually convex.
- To attach the pad retaining spring barbs may be formed in the two opposite end portions of the peripheral edge of the pad carrier plate, in which the pad retaining spring engages positively in the clamping direction of the spring, for which purpose these barbs each pass through an insertion opening of the pad retaining spring.
- the application-side and / or the reaction-side brake lining may be held radially resiliently on the brake caliper in the sense of the invention.
- Said pad retaining clip which forms the clamping element, according to an advantageous embodiment of the invention, two parallel and spaced apart in the axial direction of the brake disc extending open longitudinal slots, which are arranged in the two opposite edge regions of the longitudinal sides of the pad holding bracket and open in the insertion direction are so that form on the outside two tines, each undercut a groove-shaped recess of the pad retaining spring, said tines have said insertion bevels.
- a so-called central web which is delimited by the two longitudinal slots, rests on the pad retaining spring, so that the pad retaining spring is held in any radial direction.
- the pad retaining bracket is also formed when both brake pads are kept within the meaning of the invention.
- the lining retaining clip spans the assembly opening and is fastened to the brake caliper, for this purpose, for example, inserted into an integrally formed pocket and, on the other hand, pushed into a hook-shaped receptacle which are both provided in the edge region of the caliper bordering the assembly opening.
- the brake lining according to the invention which has a lining carrier plate and a friction lining fastened thereon, is designed such that at an edge edge of the lining carrier plate, the lining retaining spring is attached, wherein said at least one, over the width of the lining retaining spring extending groove which is recessed in the direction away from the lining carrier plate direction.
- this channel can be designed square or round in cross section.
- FIG. 1 shows an embodiment of a disc brake according to the invention in a perspective view
- Figure 3 is a section through the disc brake according to the line
- Figure 4 shows the disc brake of Figure 2 in a cut
- Figures 5 and 6 are each a detail of the disc brake in a perspective view
- Figure 7 shows another embodiment of an inventive
- Figures 8 and 9 are each a detail of the disc brake of Figure 7, also shown schematically.
- FIGS. 1 and 2 depict a disc brake for a commercial vehicle, with a brake caliper 1 which engages over a brake disc 2 and adjoins it a stationary brake carrier 6, relative to the brake disc 2 is mounted axially displaceable.
- a disc brake is also known as Schiebesattel- disc brake.
- the brake carrier 6 has two lining shafts 7, one of which is shown in FIG. In each of these lining shafts 7, a brake pad 3, 3 'is held, wherein in the figure 4 a zuspann perfumeer brake pad 3 can be seen.
- Each brake pad 3, 3 ' has a lining carrier plate 4 and a friction lining 5 held thereon, which are pressed against the brake disk 2 on both sides during braking.
- the lining shaft 7 is bounded in the circumferential direction of the brake disk 2 by two brake carrier horns 8 which have stops 9 protruding into the lining shaft 7 on their sides facing a mounting opening 14 of the brake caliper 1, where the pad carrier plate 4 of the brake pad 3 spring-loaded with a gradation 23, so that the brake pad 3 is secured in the direction of the mounting hole 14.
- the brake lining 3 is positioned with play at least at the bottom of the lining shaft 7.
- FIG. 2, as well as FIG. 1, illustrate that in the example the tension-side brake pad 3 according to the invention is held radially resiliently on the brake caliper 1.
- the brake lining 3 has a lining holding spring 10 attached to the peripheral edge of the lining carrier plate 4 facing the assembly opening 14, which is in engagement with a clamping element designed as a lining holding clip 11.
- the pad retaining spring 10 is in the attack region of the pad retaining clip 1 1 with two parallel and spaced apart, extending over the width of the pad retaining spring 10 extending grooves 18 which are outwardly curved, ie in the pad carrier plate facing away from the direction and in which two prongs 17th of the pad retaining clip 1 1 are guided, these prongs 17 engage under the pad retaining spring 10.
- Figure 5 shows the pad retaining spring 10 as a detail
- the figure 6 illustrates the pad retaining bracket 1 1 as a detail
- the prongs 17 are formed by two parallel and spaced apart continuous and open at one end longitudinal slots 15, while the resulting center region, which is bounded by the longitudinal slots 15, forms a web 16 which in the mounted position on the pad retaining spring 10 and that rests between the two grooves 18.
- FIG. 6 shows particularly clearly that the tines 17 in their free end region each have an insertion bevel 22, which makes it possible to easily slide the pad retaining clip 11 onto the pad retaining spring 10.
- Brake disk 2 is pushed into the lining shaft 7, where it is arranged with the gradations 23 below the stops 9, while resting on the bottom of the lining shaft 7. Subsequently, the lining retaining clip 1 1 with its tines 17 under the pad retaining spring 10 in the region of the grooves Pushed 18, wherein the web 16 comes to rest on the leaf spring 10 between the oppositely raised grooves 18. Here, the brake pad 3 is pulled almost under spring load against the stops 9, with game formation against the bottom of the lining shaft. 7
- the through-openings 20 of the pad retaining springs 10, 10th ' pass through and under appropriate deformation of the pad retaining springs 10, 10 ' behind the undercuts of the barbs 19 hintergrei-.
- the reaction-side brake pad 3 ' is pressed under bias of the pad retaining spring 10 ' in correspondence with the pad retaining clip 1 1 in the associated pad slot 7 of the brake carrier 6.
