- the carrier element is preferably a carrier plate.
- the friction plate or the carrier plate of the friction plate is slightly wavy.
- the counter-coupling part is, for example, a steel plate. Due to the reduced coefficients of friction in the area of the peaks of the wave crests, the friction lining is optimized at the contact points with the adjacent steel plates. The contact points on the friction plates are always the high points of the corrugation, because only there does the friction lining slide along the adjacent steel plates in the opened state of the friction coupling.
- a preferred embodiment of the friction clutch is characterized in that the friction lining has a smaller outer radius in the region of the peaks of the wave crests in order to reduce the friction in the region of the peaks of the wave crests. Due to the smaller outer radius, the friction surface in the region of the peaks of the wave crests can be reduced in a simple manner.
- a further preferred embodiment of the friction clutch is characterized in that the friction lining in the region of the high points of the wave crests has a larger inner radius in order to reduce the friction in the region of the high points of the wave crests. Due to the larger inner radius, the friction surface in the area of the peaks of the wave crests can be reduced in a simple way.
- the friction lining in the region of the high points of the wave crests both a smaller outer radius and a larger inner radius.
- a further preferred embodiment of the friction clutch is characterized in that the friction lining is provided in the region of the high points of the wave crests with more grooves in order to reduce the friction in the region of the high points of the wave crests.
- a further preferred embodiment of the friction clutch is characterized in that the friction lining in the region of the high points of the wave crests is provided with larger grooves in order to reduce the friction in the region of the high points of the wave mountains. Due to the larger grooves, the friction surface in the region of the peaks of the wave crests can be reduced in a simple manner. According to a further aspect, the friction lining in the region of the peaks of the wave crests is provided both with more grooves and with larger grooves.
- a further preferred embodiment of the friction clutch is characterized in that the friction lining in the region of the high points of the wave crests in each case has at least one constriction in order to reduce the friction in the region of the high points of the wave crests. The constriction creates a smooth transition from areas with larger outer radii / smaller inner radii to a region with a smaller outer radius / larger inner radius in the region of a high point of a wave crest.
- a further preferred embodiment of the friction clutch is characterized in that the friction lining is formed from friction lining pieces, wherein in the rich of peaks of the wave peaks fewer friction lining pieces are arranged to reduce the friction in the region of the peaks of the wave crests. As a result, the friction surface in the region of the peaks of the wave crests can be reduced in a simple manner.
- a further preferred exemplary embodiment of the friction clutch is characterized in that the friction lining is formed from friction lining pieces, smaller friction lining pieces being arranged in the region of the peaks of the wave crests in order to reduce the friction in the region of the peaks of the wave crests. Due to the smaller friction lining pieces, the friction surface in the region of the peaks of the wave crests can be reduced in a simple manner.
