  • Friction clutch with spring compensating the change in pressure force due to wear
    Patent number: 6029792
    Abstract: A friction clutch whereby the operating force characteristic is made largely independent of the wear of the clutch disk. The friction clutch is characterized in that in the engaged position of the clutch, the initial position of a clutch plate corresponding to an initial thickness of the clutch disk corresponds to a stop position of a spring in the direction of a displacement of a pressure plate against the clutch disk, from which the spring produces the superimposed elastic force when the pressure plate is displaced in the direction of clutch disk.
