ABSTRACT:
According to an example embodiment of this invention, a clutch disc comprises a primary hub, a seconday hub and a lining carrier. The primary hub is angularly movable with respect to the secondary hub and the secondary hub is angularly movable with respect to the lining carrier. First load transmitting springs are provided between the primary hub and the secondary hub. Second load transmitting springs are provided between the secondary hub and the lining carrier. The second springs have a steeper spring characteristic than the first springs. Abutments are provided on both the primary hub and the secondary hub. The second springs are pre-stressed. When an increasing load is transmitted the angular movement of the secondary hub with respect to the lining carrier begins before the abutments of the primary and the secondary hubs engage each other.
