Definitions
- the invention relates to a friction pad with a friction lining that is made of a ceramic material and has a friction surface.
- a multi-layer friction lining with a carrier layer and a friction layer is known, which has a friction surface.
- a clutch disc with a friction element is known, which is designed as a ceramic component or comprises ceramic.
- a torsional vibration damper and a clutch disc with friction linings are known, which can include friction surfaces made of plastic, ceramic or the like.
- the object of the invention is to improve a friction pad with a friction lining, which is formed from a ceramic material and has a friction surface, in terms of production engineering and/or functionality.
- the object is achieved with a friction pad with a friction lining, which is formed from a ceramic material and has a friction surface, in that the friction lining has at least one recess in a bearing surface facing away from the friction surface, which is suitable for increasing a mass moment of inertia during operation of the mounted friction pad to reduce.
- the at least one recess is advantageously designed in such a way that a friction lining thickness that can be used during operation of the friction pad is not reduced in comparison to conventional friction pads. Nevertheless, the mass moment of inertia during operation of the installed friction pad can be effectively reduced by the at least one recess. In addition, expensive ceramic material can be saved compared to conventional friction pads.
- a preferred exemplary embodiment of the friction pad is characterized in that a depth dimension of the recess is at most as large as the corresponding dimension of a rivet head of a rivet element with which the friction pad can be fastened to a carrying device.
- the carrying device is, for example around a drive plate.
- the drive disk is, for example, a ring-like sheet metal part to which a large number of friction pads are fastened with the aid of rivet elements.
- the rivet head of the rivet element is arranged within the friction lining of the friction pad. Due to the presence of the rivet head, this part of the friction lining cannot be rubbed away during operation of the friction pad.
- a further preferred exemplary embodiment of the friction pad is characterized in that the depth dimension of the recess is exactly the same as the corresponding dimension of the rivet head. It is thus ensured in a simple manner that the friction lining with the at least one recess in the support surface can be used just as effectively with regard to its friction function as a conventional friction pad without a recess.
- a further preferred exemplary embodiment of the friction pad is characterized in that the friction lining made of the ceramic material is attached to a carrier element.
- the carrier element is, for example, a carrier plate, preferably made of an aluminum material, with the aid of which the friction pad is attached to the carrier device, in particular riveted.
- a further preferred exemplary embodiment of the friction pad is characterized in that the friction lining made of the ceramic material is connected to the carrier element with its supporting surface in a material-to-material manner and also in a form-fitting manner in the region of the recess.
- the bearing surface of the friction lining made of the ceramic material is firmly connected to the carrier element, for example by means of an adhesive connection.
- the carrier element advantageously engages in the recess of the bearing surface of the friction lining.
- the resulting form-fitting connection increases the stability of the attachment of the friction lining to the carrier element.
- Another preferred embodiment of the friction pad is characterized in that the recess in the friction lining is bordered by a peripheral edge with which the friction lining lies flat against the carrier element, the friction lining also lying flat on the carrier element in the region of the recess.
- a particularly stable attachment, in particular gluing, of the friction lining to the carrier element is thus made possible in a simple manner.
- a further preferred exemplary embodiment of the friction pad is characterized in that the friction pad comprises two rivet passage holes which are arranged between two recesses in the bearing surface of the friction lining.
- the rivet through-holes advantageously serve to receive a rivet element each, with which the friction pad, in particular the carrier element of the friction pad, is fastened to the carrier device.
- a further preferred exemplary embodiment of the friction pad is characterized in that the friction pad is designed symmetrically between centers of the rivet through-holes in relation to a connecting line.
- the rivet passage holes are advantageously arranged in the area of a connecting web, which in turn is arranged between two recesses in the bearing surface of the friction lining. This simplifies the manufacture and assembly of the friction pad.
- Another preferred exemplary embodiment of the friction pad is characterized in that the recess or the recesses take up or take up at least one third of the bearing surface of the friction lining. In this way, the production costs, in particular the amount of ceramic material required, can be effectively reduced.
- a further preferred exemplary embodiment of the friction pad is characterized in that the carrier element is designed as a carrier plate.
- the support plate is formed of an aluminum material, for example.
- the carrier plate, in particular made of aluminum material, can be adapted relatively easily to the shape of the friction lining in the area of the recesses.
- the invention also relates to a brake disk or a clutch disk with a driver disk, to which at least one friction pad described above is fastened, optionally with at least one spring segment interposed.
- the brake disc or clutch disc is preferably used in commercial vehicles, in particular in trucks or tractors. Further advantages, features and details of the invention result from the following description, in which various exemplary embodiments are described in detail with reference to the drawing. Show it:
- FIG. 1 shows a perspective representation of a friction pad with a friction lining, which is fastened to a carrier element, whose side facing away from the friction lining is shown in FIG
- FIG. 2 shows the friction pad from FIG. 1 with a view of the friction lining
- FIG. 3 shows the friction pad from FIG. 1 in a perspective sectional view
- FIG. 4 shows the friction pad from FIG. 2 in a perspective representation.
- the friction pad 1 includes a friction lining 2 made of a ceramic material.
- a friction surface 3 of the friction lining 2 is seen.
- the support member 17 is formed from an aluminum sheet material.
- the friction lining 2 is integrally connected to the carrier element 17 on its supporting surface 4 .
- the friction lining 2 is positively connected to the carrier element 17 in the area of the recesses 11 , 12 .
- the recesses 11 , 12 are formed both in the friction lining 2 and in the carrier element 17 . This results in a positive connection between the friction lining 2 and the carrier element 17 in the area of the recesses 11, 12.
- the friction pad 1 also includes two rivet through-holes 5, 6.
- the rivet through-holes 5, 6 serve to receive rivet elements 7, 8, of which rivet heads 9, 10 can be seen in FIGS.
- the rivet elements 7, 8 are used for Fastening of the friction pad 1 with the carrier element 17 to a carrier device (not shown), such as a drive plate.
- FIG. 1 It can be seen in FIG. 1 that the recesses 11, 12 are bordered on a peripheral edge 13, 14 in each case.
- a connecting web 15 is formed between the two recesses 11 , 12 .
- the two rivet through holes 5, 6 are arranged in the connecting web 15.
- the friction pad 1 with the friction lining 2 and the carrier element 17 is symmetrical in relation to a connecting line 16 which extends through the centers of the rivet through-holes 5, 6.
- Arrows 18, 19 in Figure 4 indicate that the effective thickness of the friction lining 2 is not affected by the recesses 11, 12, since the recesses 11, 12 have the same depth or height as the rivet heads 9, 10 of the rivet elements 7, 8 to have.
