Multiple disc brake system
First Claim
1. A disc brake system comprising a hub which is arranged to rotate about an axis thereof, a disc disposed about said hub and extending radially from said hub and said axis thereof, a plurality of axially-extending grooves formed in the hub and teeth projecting radially inwardly from the disc into said grooves, each tooth being a sliding fit in one of said grooves whereby said disc is axially slideable on said hub, and springs located in at least some of said grooves and engaging said teeth of the disc which project into those grooves and applying a radial outward force to said teeth.

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 system (10) also comprises a mounting arrangement (20,22) by which the disc (12,14) is mounted on the hub (16) so that the hub and the disc rotate as a unit about the axis (18) and the disc can perform axial sliding movement on said hub. The mounting arrangement comprises a plurality of axially-extending grooves (20) formed in the hub (16) and teeth (22) projecting from the disc (12,14) into the grooves. The system (10) also comprises springs (32,42) located in at least some of the grooves (20) and engaging the teeth (22) acting to apply radial force between the disc (12,14) and the hub (16).

13. A disc brake system, comprising:
-
a hub rotatable about an axis of said hub and formed with a plurality of axially extending grooves;
a disc disposed about said hub and extending radially from said hub and having a plurality of teeth extending radially inwardly into said grooves of said hub and supporting said disc for axial sliding movement on said hub while supporting said disc against relative rotational movement on said hub; and
a spring disposed in at least one of said grooves and acting on said disc to apply a radial outward force on at least one of said teeth of said disc associated with said at least one of said grooves.

14. A disc brake system comprising a hub which is arranged to rotate about an axis thereof, a disc disposed about said hub and extending radially from said hub and said axis thereof, a plurality of axially-extending grooves formed in the hub and teeth projecting radially inwardly from the disc into said grooves, each tooth being a sliding fit in one of said grooves whereby said disc is axially slideable on said hub, and leaf springs located in at least some of said grooves and engaging said teeth of the disc which project into those grooves and applying a radial outward force to said teeth, each of said leaf springs including a plurality of parallel ridges extending axially for remaining in engagement with the disc as said disc moves on said hub.
