Disc brake system
First Claim
1. A disc brake system comprising a disc, and a hub which is arranged to rotate about an axis thereof, the hub comprising a mounting portion which is generally in the shape of a hollow cylinder having an external surface and an interior, the system also comprising mounting means by which the disc is mounted on the external surface of said mounting portion for rotation with said hub as a unit about said axis and so that the disc can perform axial sliding movement on said hub, wherein said hub carries vanes spaced from said disc arranged so that, during rotation of the hub about said axis, the vanes act to force air into the interior of said mounting portion, and in that said mounting portion has openings therethrough arranged so that air forced into the interior of the mounting portion passes through said openings and flows over said disc.

Abstract
A disc brake system (10) comprises a disc (12, 14), and a hub (16) which is arranged to rotate about an axis (18) thereof. The hub (16) comprises a mounting portion (16d) which is generally in the shape of a hollow cylinder. The system (10) also comprises grooves (20) and teeth (22) by which the disc (12, 14) is mounted on the external surface of the mounting portion (16d) for rotation with the hub (16) as a unit about the axis (18) and the disc (12, 14) can perform axial sliding movement on the hub. The hub (16) carries vanes (62) arranged so that, during rotation of the hub (16) about the axis (18), the vanes act to force air into the interior of the mounting portion (16d). The mounting portion (16d) has openings (60) therethrough arranged so that air forced into the interior of the mounting portion (16d) passes through the openings and flows over said disc (12, 14).

16. A disc brake system comprising a disc, and a hub which is arranged to rotate about an axis thereof, said hub comprising a mounting portion which is generally in the shape of a hollow cylinder having an external surface and an interior, said disc being mounted on the external surface of said mounting portion for rotation with said hub as a unit about said axis and so that said disc can perform axial sliding movement on said hub, wherein said hub carries vanes arranged so that, during rotation of said hub about said axis, said vanes act to force air into said interior of said mounting portion, and in that said mounting portion has openings therethrough arranged so that air forced into said interior of said mounting portion passes through said openings and flows over said disc, said hub including a plurality of grooves extending axially of said hub and teeth projecting from said disc into said grooves, each of said teeth being in sliding fit relation in an associated one of said grooves, said openings being formed in portions of said hub which are between said grooves, and a plurality of leaf springs mounted on said hub on portions thereof which are between said grooves, said leaf springs acting to apply radial force between said disc and said hub, said springs having openings therethrough which correspond to said openings in said hub.
