Definitions
- the invention relates to a brake carrier for a commercial vehicle disc brake whose brake caliper surrounds the brake disc in the form of a frame, with a flange surface lying parallel to the brake disc plane, wherein the brake carrier has no parts which engage the brake disc in the installed state.
- the brake carrier is plate-shaped. It serves only to hold or guide the brake pad on the tensioning side and optionally of a pressure plate, but not to hold or guide a rim-side brake pad. This results in considerable advantages, in particular for larger brakes, such as those used for commercial vehicles.
- a brake carrier serves, inter alia, to attach the caliper of the disc brake to the fixed part of an axle arrangement or to an axle flange, usually by screwing.
- a comparable brake carrier is known, for example, from DE 695 14 482 T2. It is plate-shaped because it does not overwhelm the brake disc. but not suitable for commercial vehicles, because it is too unstable and does not fulfill important functions in brakes for commercial vehicles.
- brake carrier for example, frame-shaped and engage around the brake disc. They thus serve to support and guide brake linings on both sides.
- the brake linings are pressed axially against the brake disk by means of a mechanical clamping device provided in the brake caliper and via the brake caliper mounted on slide pins. Brake circumferential forces are transmitted to the axle arrangement via the brake carrier bolted to the axle arrangement by means of axial screwing.
- Such brake carriers are made especially when used in commercial vehicles because of high demands on the strength of cast material and take up considerable space to complete. In addition, they increase the weight of the unsprung masses and require considerable manufacturing effort. In particular, the production effort is therefore very high because, conventionally, the brake carrier, with the entire side facing away from the brake disk, rests completely on a corresponding surface of the axle arrangement and is screwed therewith. These surfaces must be particularly flat, which brings considerable production costs. Furthermore, extensive evenness is required for surfaces which belong to radial and lateral guide or support areas for the brake linings, and also for fitting collars against which the respective slide pin is screwed with its protective cap for the brake caliper. Furthermore, the manufacturing cost is increased by the fact that conventional brake carriers are designed only for either brakes on the left side or brakes on the right side of a vehicle, which is why different designs have to be made and stored.
- the invention therefore has the object to improve the brake carrier of the type mentioned ge to the effect that material and thus weight is saved, the mechanical processing is simplified and the reliability is increased.
- the stated object is achieved in that the flange has at least two parts, which are each formed on a located on the brake disc side facing away from the brake carrier approach.
- the embodiment according to the invention has several advantages over a full surface contact surface, as provided in conventional brakes: on the one hand, the design using the approaches achieves the same strength with less material and weight as with a solid material. On the other hand, the surface to be machined is reduced. In addition, a greater brake safety is achieved. Since there can be different processing qualities in the case of full-area contact areas between the axle arrangement of one manufacturer and the brake carrier of the other manufacturer, the above-mentioned gap formations can not be ruled out. However, this is prevented by the limited (limited) contact surface on the approaches. In addition, can be achieved on the demanded by the brake or axle manufacturers tightening torques of the screws commonly used for flanging better local frictional connections between the parts. According to the invention, the two flange surface parts preferably lie in one plane. As a result, the brake carrier is suitable for being attached to the flange of an axle arrangement which is flat over its entire surface.
- At least one of the lugs annularly surrounds a recess for a fastening screw. This ensures that the brake carrier does not warp when tightening the mounting screw.
- At least one guide projection situated on the side of the brake carrier facing away from the brake disk is provided for guiding a pressure plate of the brake. Because of this guiding approach, the brake carrier need not be so thick that it has a guide device for guiding the brake pad and the pressure plate in axially successive areas. Rather, the brake carrier can be reduced by that thickness, which is needed for guiding the pressure plate, because this part of the guide is formed on the approach. Overall, the brake carrier will therefore be made less thick, which material and thus weight is saved.
- the guide groove is inclined relative to a rotational axis of the brake disc. It lies in particular when driving forward on the Bremsscaleneinlaufsei- te. So she is employed obliquely against the brake disc inlet. As a result, the pressure plate is supported running diagonally. It is pulled when braking so.
- this groove edge limits excessive lateral movement of the pressure plate, because it acts as a slanted stop for the pressure plate.
- At least one groove flank of the guide groove is über ⁇ over a groove bottom of the guide groove.
- the groove according to this embodiment of the invention at least in a part of its longitudinal extent "open” executed. This has the following reason:
- a groove guide with a U-shaped base can serve to guide a pressure plate by means of a projection. Since, in particular, this sliding guide region significantly influences the proper function / mode of operation of the pressure plate, interference effects of any kind-such as, for example, lining abrasion and dirt through the driving operation-can have a detrimental effect on the clearance of the pressure plate. Since a completely closed groove tends to accumulate dirt with clogging, and thus can lead to Ver ⁇ clamping the pressure plate guided therein, the groove is preferably designed according to the invention at least in the supernatant through the plate-shaped brake carrier as an open guide.
- the groove flanks for the pressure plate suspended therein are not U-shaped closed, but formed on both sides by projecting ribs, against which the approach of the pressure plate according to the direction of rotation of the brake disc an ⁇ sets.
- a self-cleaning guide device is created as a result of driving, in the main area in which the pressure plate moves in the direction of the brake disc as a result of pad / Scheibenverschl constructive.
- a guide groove is provided on the guide lug.
- Brake carrier can be produced by casting, which has a guide lug. After that, the guide groove can be formed without much effort on the guide projection, for example by milling.
- a first guide projection is preferably provided on the disk inlet side and a second guide projection on the disk outlet side.
- This embodiment makes it possible to design the brake carrier for left-side brakes and at the same time for brakes located on the right side. It is only on the final decision about the page that the guide groove on the corresponding page must be formed. Of course, it is also possible to form two guide grooves. There- by the brake carrier would then arbitrarily on the right and the left side ein ⁇ bar.
- a passage opening and / or a region of reduced material thickness outside the main power flow lines in deriving the braking force is provided.
- the brake carrier has a "ribbed structure", wherein the ribs coincide with the main power flow lines.
- a stop for limiting a displacement of the caliper in the axial direction of the brake disc is preferably provided.
- Such a stop serves to prevent the caliper from either crushing or lifting a protective cap of a slide pin, depending on which direction the caliper could be displaced excessively. This excessive displacement is limited by the stop according to the invention.
- an approach according to the invention further preferably serves to limit a displacement of the caliper in both directions along an axis of rotation of the brake disk.
- excessive displacement in both directions is preferably prevented in order, for example, to protect a protective cap from being crushed both before it is crushed and before it is lifted.
- At least two lugs are provided, which are symmetrical to each other, so for example a sol ⁇ cher approach on the disc inlet side and one on the disc outlet side.
- FIG. 1 shows a schematic view of a brake carrier according to an embodiment of the invention in Axialrich ⁇ direction of the brake disc seen
- FIG. 2 shows a schematic plan view of the brake carrier according to claim 1
- FIG. 3 shows a schematic perspective view of the brake carrier according to FIG. 1,
- FIG. 4 shows a schematic exploded view of the brake carrier together with other functional parts of a brake
- Figures 5 and 6 are schematic perspective views of brake parts in different operating states.
- the brake carrier 1 shown in the drawing is used to hold or carry a caliper 2, a brake pad 3 and a pressure plate 4 against which presses a Zuspannst Congressel 5 during braking.
- the brake carrier 1 is located for attachment with its side shown in Figure 2 below on a (not shown) axle flange.
- six recesses in particular threaded bores 10 10, 12, 14, 16, 18, 20 are used, into which fastening screws (not shown) are screwed.
- the recesses are each surrounded by a projection 22, 24, 26, 28, 30, 32 or circulate annularly.
- the end faces 34, 36, 38, 40, 42, 44 of the lugs are machined, for example by milling, so that they are exactly flat, in extremely tight tolerances Tole ⁇ .
- the brake carrier has window-like recesses 46, 48, which contribute to further material savings and thus to weight reduction. Since only the end faces 34, 36, 38, 40, 42, 44 serve to rest on the flange surface of the axle arrangement, the window-like recesses 46 and 48 can be formed without impairing the function. For the same reason, a connecting yoke 50 can be made very narrow.
- the brake pad is supported and guided in the installed state of surfaces 60, 62, 64, 66.
- the surfaces 60 and 64 serve to receive the brake circumferential forces which are transmitted to the axle arrangement via the screws stuck in the recesses 10, 12, 14, 16, 18, 20.
- one of the main power flow lines runs approximately from the surface 64 via the slide pin arranged in the recess 54 to the projection 30. It should be expressly pointed out that the connection yoke 50 and the window-like recess 48 are outside this power flow line lies. Of course, the same also applies to the window-like recess 46.
- guide lugs 67, 68 are provided on the brake carrier shown in the drawing.
- a guide groove 70 is milled, which is inclined relative to a rotational axis of the brake disc.
- This guide groove 70 serves in particular in that region which projects beyond the side of the brake carrier facing the axle arrangement, the support and / or guidance of the pressure plate already mentioned above.
- Characterized in that the guide groove 70 is formed in particular in that area which projects beyond the side facing the axle assembly, material and thus weight can be saved considerably wer ⁇ . Namely, in particular, for example, not the connection yoke 50 must be made so thick that the guide groove 70 could be formed thereon.
- the brake carrier 1 shown in the drawing is a left-hand brake carrier, ie a brake carrier, which is mounted on the left side of a vehicle, in particular a commercial vehicle, in the direction of travel. DEM Correspondingly, in FIG. 1, the rotational direction D of the brake disk coincides with the clockwise direction.
- the pressure plate 4 is advantageously mounted on the Scheibeneinlaufseite in the guide groove 70, with a projection. 6
- the brake carrier is to be used on the right-hand side of the vehicle, only one groove 70 corresponding to the guide groove 70 has to be formed on the shoulder 68.
- the brake carrier shown in the drawing can therefore be used universally without major measures. As a result, the requirement for stockpiling significantly reduced because no longer two different brake carrier must be made and stored.
- the brake carrier 1 shown in the drawing has two lugs 72, 74.
- the two stops 72, 74 form a stop 76, 78 on their side facing the brake disc.
- the stops 76, 78 lie in such a way that the brake caliper 2, which engages over the brake disc in a frame-shaped manner, is limited in the direction of the application side due to excessive displacement, because he strikes at the stops 76, 78.
- protective caps are prevented from sliding pins in the slide pin bearings 52, 54.
- a similar purpose serve stops 80, 82. However, they prevent excessive displacement of the caliper 2 in the direction of the rim side, which could lead to Zer ⁇ squeezing the protective caps.
- the stops 80, 82 and the zuwoods paragraphen surfaces of the lugs 72, 74 serve as a shift limit stop for the saddle 2.
- the projection 72 cooperates with stops 72.1 and 72.2, which are formed on the saddle 2.
- the stop 72.1 serves to limit a displacement of the saddle 2 in the direction of the tension side.
- the stop 72.2 serves to limit a displacement of the saddle 2 in the direction of the rim side.
- Corresponding extreme positions of the saddle 2 are shown in FIGS. 5 and 6.
- the two approaches 72 and 74 are with respect to a Symmetry line that divides the brake carrier 1 in an inlet side and an outlet side arranged symmetrically.
