Disc brake rotor assembly

A disc brake rotor assembly comprising:

• a disc brake rotor having a plurality of partial keyways and a central opening,
• a wheel hub having a plurality of partial keyways and a central opening,
• the disc brake rotor installed on the wheel hub such that the partial keyways in the disc brake rotor and the partial keyways in the wheel hub are aligned to form completed keyways, and
• a plurality of elongate spring pins each having a length, each spring pin inserted into one of the completed keyways,
• the disc brake rotor and the wheel hub being rotatable about a central axis that extends through centers of the central openings of the disc brake rotor and the wheel hub, and
• the completed keyways orienting the pins so that the lengths thereof extend parallel to the central axis.

A disc brake rotor assembly comprising:

• a disc brake rotor having a plurality of partial keyways with first arcuate surfaces,
• a wheel hub having a plurality of partial keyways having second arcuate surfaces,
• the disc brake rotor installed on the wheel hub such that the partial keyways in the disc brake rotor and the partial keyways in the wheel hub are aligned to form completed keyways with the first and second arcuate surfaces of each completed keyway facing each other,
• a plurality of pins, each pin inserted into one of the completed keyways and held between the facing, first and second arcuate surfaces of the one completed keyway, and
• a spacer adjacent the wheel hub and the disc brake rotor.

A disc brake rotor assembly comprising:

• a disc brake rotor having a plurality of partial keyways and retaining grooves,
• a wheel hub having an inward end with a plurality of partial keyways,
• the disc brake rotor installed on the wheel hub such that the partial keyways in the disc brake rotor and the partial keyways in the wheel hub are aligned to form completed keyways,
• a plurality of pins, each pin combined with a threaded fastener and then inserted into one of the completed keyways.
