Centre-lock attachment arrangement for composite wheels

A centre-lock attachment arrangement configured to attach at least one composite wheel to a mount using a centre-lock fastener and a centre-lock fastening nut which can be fastened on the centre-lock fastener, the composite wheel including a central attachment area having a composite wheel central attachment aperture through which the centre-lock fastener is inserted, and a plurality of composite wheel fastener apertures annularly spaced around the composite wheel central attachment aperture, the centre-lock attachment arrangement including:

• a front element including a front element outer engagement surface configured to engage the centre-lock fastening nut, and a front element inner engagement surface configured to engage with an outer side of the central attachment area of the composite wheel, the front element including a front element attachment aperture through which the centre-lock fastener is inserted and a plurality of front element fastener apertures annularly spaced around the front element attachment aperture, said front element fastener apertures being complementary to the composite wheel fastener apertures of the central attachment area of the composite wheel;
• a backing element including a backing element outer engagement surface configured to face the mount, and a backing element inner engagement surface configured to engage with an inner side of the central attachment area of the composite wheel, the backing element including a backing element attachment aperture through which the centre-lock fastener is inserted and a plurality of backing element fastener apertures spaced apart around the backing element attachment aperture, said backing element fastener apertures being complementary to the composite wheel fastener apertures of the central attachment area of the composite wheel;
• and
• a plurality of elongate fasteners configured to be received through the plurality of front element fastener apertures and the plurality of backing element fastener apertures which are aligned, the plurality of elongate fasteners configured to clamp the front element and the backing element over and around the central attachment area of the composite wheel.
