Definitions

• the invention relates to a disc brake, in particular for commercial vehicles, with a brake pad, an application device for pressing the brake pad against a brake disc, a pressure plate over which the application device presses the brake pad against the brake disc during braking, and a skewed guide, the pressure plate during braking along a lying obliquely to the brake axle path.
• Disc brakes of the type mentioned are known, for example from EP 1 637 759 A1.
• Such brakes are for example pneumatically and / or electromechanically actuated. It is arranged over a relatively small attack surface of the arranged in the caliper ten application device via at least one pressure spindle device a large force component perpendicular to the brake disc plane on a large, from a lining carrier plate (back plate) and an attached, when braking the brake disc contacting friction lining existing brake pad initiated.
• a pressure plate or pressure distribution plate is used in brakes according to the invention between the application device and the back plate.
• This pressure plate is designed to be rigid so that it ensures over their approximately over the surface of the back plate extending contact surface that the brake pad is pressed as evenly and without deformation against the brake disc.
• the invention relates in particular to such brakes, in which both the brake pad and the pressure plate are separate components and installed radially on a brake caliper opening in the brake or removed. This takes place during replacement, when servicing a brake inspection and a Druckplatten- and / or brake pad change.
• the pressure plate is not wider than the brake pad.
• the two components brake pad and pressure plate mentioned are for example on the application side in a stationary brake carrier and / or in the caliper in shaft guides laterally and / or radially inwardly on the largest possible contact surfaces out / supported by these surfaces.
• the two-sided boundaries for the brake pad can be formed by Abstütz Anlagennern.
• the brake lining is often performed on contact surfaces that lie on approaches or on a connecting yoke between the Abstweil Anlagennern.
• the pressure plate is guided only radially on these contact surfaces, wherein it additionally engages in a groove of the brake carrier or of the brake caliper via a lower-lying projection (anti-rotation lock), for which reason a positive guidance is present.
• the pressure plate is thus "suspended.”
• the above-mentioned groove in preferred direction of rotation of the brake disc in forward travel is always radially approximately in the present contact surface on the brake disk inlet side, wherein the groove is also employed at an angle to the disc inlet.
• the groove is also employed at an angle to the disc inlet.
• the invention is particularly applicable to disc brakes in which the brake pads and the pressure plate are clamped by means of hold-down springs and a hold-down in the required position to avoid rattling noises and as a safeguard against falling out of the brake.
• the task set is achieved by a projection on the pressure plate and a recess on the brake pad, which receives the projection in the assembled state.
• This is a coding. It is based in particular on the printing plate.
• the pressure plate thereby fits together only with the associated brake pad.
• a clearance between a side boundary of the projection and the associated inner boundary of the recess is provided.
• the depth of the recess corresponds at least to the thickness of a back plate of the brake pad. If the brake pad is moved further when it falls below the permissible residual lining / brake disc thickness, it nevertheless surrounds the projection and "hangs" depending on the position and disc direction so that it can not be torn into the space between the brake disc and shaft guide.
• the projection in the radially inner region of the pressure plate and / or the recess in the radially inner region of the brake pad is / are. Because, for example, built-in pressure plate of the brake pad is used directly radially and the recess does not necessarily encompass the projection necessarily on all sides, no axial movement of the brake pad with respect to the pressure plate are required to to spend the two components in contact with each other. This is true not only for the assembly, but also for the disassembly.
• the projection is inventively further preferably integrally formed with the pressure plate. This reduces the number of parts. Furthermore, the installation / removal is particularly simple.
• the pressure plate is a separate component.
• the coding according to the invention does not require a recess in the form of a passage opening. Rather, the recess may also have the shape of a depression (blind hole). It also does not have to be bounded on all sides by side walls. Rather, the side walls can also form a "U".

• an application device not shown here, for applying the brake. When braking, it presses against the pressure plate 20, which in turn presses the brake pad 18 against a brake disc, not shown in the drawing.
• the brake disk plane B is shown in dashed lines.
• the occurring reaction force shifts the caliper 10 in Figure 1 down, whereby the brake pad 16 is pressed against the brake disc.
• To the application device includes a pressure spindle device also not shown in the drawing, by means of which the brake can be adjusted to compensate for wear.
• the preferred direction of rotation of the brake disc during forward travel is indicated by an arrow D.
• the brake pads 16, 18 and the pressure plate 20 are guided and / or supported in shaft guides of the caliper 10 and / or the brake carrier 14. They can be mounted / dismounted through the opening 12.
• Figure 2 shows the application-side brake pad 8 with the underlying pressure plate 20 (dashed line), which are both within a substantially U-shaped shaft guide.
• Figure 3 shows a brake member with the guides for the pressure plate 20 and the present brake pad 18 seen from the Zuspannseite. The brake pad 18 is wider than the pressure plate 20th
• To the shaft guides include plants 30, 32, which act in the circumferential direction, and supports 34, 36, which act in the radial direction, always with respect to the brake axis A.
• the pressure plate 20 on a guide projection 38 which is guided in a guide groove 40 in the brake carrier 24.
• the guide groove 40 is made with respect to the brake axis A by an angle ⁇ , so that it extends obliquely. So there is a skewed guide of the pressure plate 20 before.
• the angle ⁇ is to be chosen according to the other conditions.
• the inclined guide has significant advantages. In this context, reference is made to EP 1 637 759 A1.
• the brake pad 18 each have a recess 42, 44. In the recess 44 engages a formed on the pressure plate 20 projection 46 in the assembled state. As can be seen in particular the sectional view of Figure 6, the projection 46 is hook-shaped in the illustrated embodiment.
• the recess 44 is formed both on the back plate 48 and on the friction lining 50 of the brake pad 18, for which reason its depth is equal to or slightly greater than the thickness of the back plate 48.
• the hook-shaped projection 46 can still hold the brake lining 18 even when the friction lining 50 is largely used up.
• the length at which the hook-shaped projection 46 protrudes into the recess 44 sufficiently dimensioned in this regard.
• This embodiment of the invention has the advantage that the side of the pressure plate hook-shaped formed and projecting projection in the recess or recess of the back plate is immersed, which is not in the region of the immediate contact surface pressure plate side against the back plate, so that areawise no pressure transmission range from the pressure plate get lost. It can continue to build up no material stresses.
• this also applies to more than one projection or more than one recess in all versions.
• the projection 46 engages with lateral play in the recess 44 a. This game is necessary in view of the fact that because of the inclined guide 38, 40, the pressure plate 20 moves parallel to the brake disc with respect to the brake pad 18 when the pressure plate 20 is moved together with the brake pad 18 during braking in the direction of the brake disc.
• the brake pad 18 is provided with two recesses 42, 44, while the pressure plate 40 has a projection 46.
• the invention is not limited to this embodiment. Rather, a second projection, which, for example, engages in the recess 42, can also be provided on the pressure plate 20. But it can also be provided more recesses and more projections.
• the above-mentioned coding can be realized insofar by varying the shapes, the number and / or the positions of the recesses and / or the lugs.
• FIGs 7 to 9 the pressure plate 20 has a central projection 52 which engages in a recess 54 on the brake pad 18. As can be seen in particular Figures 8 and 9, the projection 52 is received with bilateral play in the recess 54 to account for the relative movement due to the inclined guide 38, 40 bill.
