Abstract

A disc brake rotor comprises an internally disposed splined surface defining a circular opening and including one or more axially disposed internal splines that are adapted to be received on external splines of a splined structure of a wheel hub, the surface including a non-continuity such as a cut-away portion of the surface into which independent splines are selectively actuable to align with the internal splines as a part of the surface to allow the rotor to be connected to or released from the hub without using any tools or the like. Preferably, the independent splines are finger actuable, and provide through a workpiece comprising a locking hammer of locking foot.

Claims

1. A disc brake rotor, comprising:

an internally disposed splined surface defining a circular opening and including one or more axially disposed internal splines that are adapted to be received on external splines of a splined structure of a wheel hub, said surface including a non-continuity.

2. The disc brake rotor of claim 1, wherein said non-continuity includes a cut-away portion of said surface into which independent splines are selectively actuable.

3. The disc brake rotor of claim 2, wherein said independent splines are selectively actuable to align with said internal splines as a part of said surface.

4. The disc brake rotor of claim 2, wherein said independent splines are selectively actuable to align with said internal splines as a part of said surface to allow said rotor to be connected to or released from said hub.

5. The disc brake rotor of claim 2, wherein said independent splines are selectively actuable to align with said internal splines as a part of said surface to allow said rotor to be connected to or released from said hub without using any tools or the like.

6. The disc brake rotor of claim 2, wherein said independent splines are finger actuable.

7. A disc brake rotor, comprising:

a non-continuous internally disposed splined surface defining a circular opening and including one or more axially disposed internal splines that are adapted to be received on external splines of a splined structure of a wheel hub.

8. The disc brake rotor of claim 7, wherein said surface is adapted to receive independent splines to align with said internal splines as a part of said surface.

9. The disc brake rotor of claim 8, wherein said independent splines are selectively actuable to align with said internal splines as a part of said surface.

10. The disc brake rotor of claim 8, wherein said independent splines are selectively actuable to align with said internal splines as a part of said surface to allow said rotor to be connected to or released from said hub.

11. The disc brake rotor of claim 8, wherein said independent splines are selectively actuable to align with said internal splines as a part of said surface to allow said rotor to be connected to or released from said hub without using any tools or the like.

12. A disc brake rotor, comprising:

an internally disposed splined surface defining a circular opening and including one or more axially disposed internal splines that are adapted to be received on external splines of a splined structure of a wheel hub; and

a workpiece having independent splines that are selectively actuable to align with said internal splines as a part of said surface.

13. The disc brake rotor of claim 12, wherein said workpiece is supported by a carrier pocket of said rotor.

14. The disc brake rotor of claim 12, wherein said workpiece includes a locking hammer that carries said independent splines.

15. The disc brake rotor of claim 14, wherein said locking hammer includes a void space into which said independent splines flex upon alignment with said internal splines.

16. The disc brake rotor of claim 14, wherein said locking hammer is rotable to bring said independent splines into alignment with said internal splines.

17. The disc brake rotor of claim 13, wherein said workpiece includes a locking foot that carries said independent splines.

18. The disc brake rotor of claim 17, wherein said locking foot is thread-wise rotable to bring said independent splines into alignment with said internal splines.

19. The disc brake rotor of claim 17, wherein said locking foot is thread-wise rotable through a thumb wheel to bring said independent splines into alignment with said internal splines.
