Abstract:
A disc brake system comprising a hub, and a disc, the hub being mounted for rotation about a central rotational axis and the disc being mounted on the hub to rotate therewith, the hub having circumferentially extending curved support surfaces each having a radius of curvature originating at the central rotational axis, the disc being slidable on the hub in a direction which is parallel to said central rotational axis, wherein the system also comprises a plurality of leaf springs distributed circumferentially around the hub, the leaf springs being secured to the curved support surface of the hub and acting to apply radially-directed forces to the disc, the springs having end portions extending tangentially away from the curved support surfaces of the hub when the disc is not mounted on the hub but are deformed to an arcuate profile between the disc and the hub by the presence of the disc.
