Problems solved by technology

Furthermore, although it is possible to achieve greater groove depths by milling compared to punching, it is also not possible here to achieve a maximum groove depth corresponding to the thickness of the friction facing, especially since in this case, There will be contact between the tool and the friction facing carrier, which can lead to tool wear or undesired removal of material from the friction facing carrier
Since, even if grooves or depressions are produced by milling, relatively expensive milling tools such as end mills have to be used, this method can only be used economically to a limited extent

Embodiment Construction

[0040] See below Figure 1 to Figure 9 An embodiment of the method according to the invention is described.

[0041] Therefore, first, a friction facing carrier 2 of a friction member 4 is prepared. The friction component 4 is preferably a friction plate 6 for a friction operating device, preferably a multi-plate clutch or multi-plate brake. The friction facing carrier 2 is substantially in the form of a circular disc or ring and has an axis of rotation 12 which extends in two opposite axial directions 8 , 10 . also in figure 1 The mutually opposing radial directions 14 , 16 and the two mutually opposing circumferential directions 18 , 20 of the friction facing carrier 2 and thus of the entire friction component 4 are indicated by corresponding arrows. The friction facing carrier 2 , which consists of metal, preferably steel, has an outer edge 22 and an inner edge 24 , which faces outwards in the radial direction 14 and which faces inwards in the radial direction. 16 on. ...

Abstract

The present invention relates to a method for producing a pattern of depressions in a friction surface (36) of a friction component (4) for a frictionally operating device, preferably a multiplate clutch or multiplate brake. After the preparation of the friction component, the pattern of depressions is produced by nontraditional material removal, removal of material preferably being accomplished in a contactless manner, particularly preferably with the aid of a laser beam. In addition, the present invention relates to a friction component having the friction surface (36), wherein the pattern with depressions produced according to the method of the present invention is provided.

Description

technical field [0001] The invention relates to a method for producing a pattern of depressions in a friction surface of a friction component of a friction running device. Furthermore, the invention relates to a friction component for a friction running device, the friction component having a friction surface in which a multi-depression pattern is provided. Background technique [0002] The prior art has disclosed friction linings for multiplate clutches which essentially consist of a friction facing carrier and a friction facing applied to one or both sides of the friction facing carrier. The side of the friction facing facing away from the friction facing carrier forms the friction surface of the friction lining. Especially in wet multiplate clutches, friction plates are used which are provided with depressions or grooves in their friction surfaces in order to exert a positive effect on the friction behavior, service life and drag torque behavior of the friction plates. ...
