The invention relates to a wet-running multi-plate clutch () comprising a number of inner plates () and a number of outer plates (), and a first friction lining () is disposed on either side of every inner plate () respectively and a second friction lining () is disposed on either side of every outer plate () respectively, and the first friction linings () are located entirely underneath the second friction linings () in the radial direction so that the first friction linings () move into frictional contact with the outer plate main bodies () when the multi-plate clutch () is engaged and the second friction linings () move into frictional contact with the inner plate main bodies () when the multi-plate clutch () is engaged. The first friction linings () respectively have at least one first groove () with a groove depth of up to 100% of a friction lining thickness of the first friction linings () and the second friction linings () have no or respectively have at least one second groove () which has a smaller cross-sectional surface area, as viewed in the longitudinal extension of the second grooves (), than the first grooves () as viewed in the same direction.

Multi-plate clutch

A friction plate for wet-running applications includes an annular main body having a first and a second surface. A friction lining having first oil grooves and second oil grooves is disposed on at least one of the first and the second surfaces. The first oil grooves extend from a radially inner end face of the friction lining in the direction towards a radially outer end face of the friction lining and terminate at a distance short of the radially outer end face, and the second oil grooves are disposed directly adjoining the first oil grooves in the radial direction and have a smaller maximum width in the circumferential direction than the first oil grooves. The first oil grooves are provided with a cross-sectional widening in the region of a radially outer end. The cross-sectional widenings of the first oil grooves are disposed at different radial heights.

Friction plate

The invention relates to a method for producing a friction element () comprising the steps: providing a metal main body (), hardening the main body () on at least part of its surface () in a salt bath, wherein the salt bath hardening is the final method step, and no further processing of the hardened surface () is performed. Furthermore, the invention relates to a friction element produced according to this method and a friction component comprising the latter.

Method for producing a friction element

The invention relates to a friction lamella () comprising a disk-shaped carrier element () having a first surface () and a second surface () opposite thereto, a first friction lining () being situated on the first surface () and a second friction lining () being situated on the second surface (), which are formed from a composite material, comprising a resin and a fibrous material, and grooves () being situated in the first and in the second friction linings (), which divide the friction linings () into segments () at least in surface-proximal areas. The segments () of the first friction lining () are implemented offset by a defined offset angle () to the segments () of the second friction lining (). Furthermore, the invention relates to a method and a device for producing the friction lamella and the use of the friction lamella.

Friction lamella

The invention relates to a method for producing a friction element () comprising the steps:

The invention relates to a method of producing a friction lining whereby a friction paper is displaced with a latex based on an elastomer and fibers of the friction paper are then bonded one another due to precipitation of the elastomer out of the latex. A non-surface active protective colloid is added to the latex as a suspension agent before applying it to the friction paper.

Method of producing a friction lining

A friction lining for wet running consists of a fabric which can be applied to a carrier ( ) and is partly impregnated with resin. In order to provide favorable friction conditions it is proposed that the porosity of the fabric ( ) impregnated with resin is higher in the zone of the friction face ( ) by a lower resin content in a surface layer (h) than in the remaining layer.

Friction lining for wet running

There is described a method of manufacturing a flat friction ring which consists of a supporting ring (,) and a friction lining (,) provided on at least one side of the supporting ring and at least approximately forming radial oil grooves (,), which friction lining is first cut out of a friction lining web including slits (,) extending from at least one circumferential side for forming the future oil grooves (,), and is then glued onto the supporting ring (,). This method is characterized in that the friction lining (,) is cut out of the friction lining web in the form of a strip (,) and in the area of the connecting webs (,) between the friction lining sectors (,) separated from each other by the slits (,) is bent in a polygon-like manner to form a ring and is glued onto the supporting ring (,).
