A wet multi-plate clutch includes a plate carrier with a pair of fluid passage openings and a friction plate rotationally fixed and axially displaceable relative to the plate carrier. The friction plate has a carrier element and a pair friction pads fastened to the carrier element and delimiting a groove. The groove includes a groove geometrical center line. The groove geometrical center line may extend radially through a one of the pair of fluid passage openings, or it may extend radially between the pair of fluid passage openings. If the groove geometrical center line extend radially between the pair of fluid passage openings, one of the pair of friction pads may include a pad geometrical center line extending along a radial extent through a one of the pair of fluid passage openings.

A method for producing a multi-layered wet friction material includes providing a bottom layer, providing a top layer produced independently of the bottom layer from different materials, and bonding the bottom layer to the top layer. The bottom layer and the top layer may be produced from different formulations and supplied as raw papers. A formulation of the top layer may include twenty to sixty percent (20%-60%) filler, ten to forty percent (10%-40%) wood pulp, five to ten percent (5%-10%) aramid, and twenty-five to thirty-five percent (25%-35%) phenolic resin. A formulation of the bottom layer may include ten to fifty percent (10%-50%) filler, ten to forty percent (10%-40%) wood pulp, five to ten percent (5%-10%) aramid, five to fifteen percent (5%-15%) carbon, and twenty-five to thirty-five percent (25%-35%) phenolic resin.

A method for producing a friction body, in particular a wet friction disk in a motor vehicle, the friction body turning about a rotational axis during operation. The friction body has a friction area and a connection area and the connection area of the friction body is connected to a friction body carrier. A friction body, in particular a wet friction disc in a motor vehicle, is also provided.

Method for producing a friction body

A method for introducing recesses in workpiece surfaces to be machined, with the aid of at least one tool. The invention is characterized in that two workpiece surfaces that face each other are simultaneously machined using the tool in order to introduce recesses into said workpiece surfaces.
