Abstract: An apparatus and a method are provided for a centerlock wheel assembly that is configured to improve driving dynamics and provide faster wheel changes. A centerlock adaptor is provided with a plurality of vehicle bolt pattern configurations disposed thereon. A first and threaded abutment are disposed on the centerlock adaptor. A hub adaptor is configured to threadingly engage with an exterior surface of the threaded abutment, thereby retaining a centerlock wheel, for example. Finally, a center cap is provided to threadingly engage with an inner surface of the threaded abutment. For each side of the vehicle, the centerlock assembly features particular threading arrangements so as to retain the centerlock wheel and counteract against various wheel dynamics. A centerlock wrench is provided to tighten and loosen the hub adaptor and center cap.

Abstract: A wheel assembly includes a central hub, an outer rim including a spoke bed wall, and a spoke unit including first and second spokes. Each of the first and second spokes extends between the outer rim and the central hub, and has a first end connected to the spoke bed wall, a second end opposite to the first end and connected to the central hub and a span portion connected between the first and second ends. The first ends of the first and second spokes are respectively formed with first and second spoke bed connection portions where the first and second spokes are respectively connected to the spoke bed wall. With respect to the central hub, the second spoke bed connection portion is radially outboard relative to and circumferentially spaced from the first spoke bed connection portion.

Abstract: A center-lock attachment arrangement for use in attaching a composite wheel to a mount. TA front element includes an outer engagement surface engaging a center-lock fastening nut and an inner engagement surface engaging an outer side of a central attachment area of the composite wheel. The front element further includes an attachment aperture through which a center-lock fastener is inserted and a plurality of fastener apertures around the attachment. A backing element includes an outer engagement surface facing the mount and an inner engagement surface engaging with an inner side of the central attachment area. The backing element further includes an attachment aperture through which the center-lock fastener is inserted and a plurality of fastener apertures around the attachment aperture. Elongate fasteners received through the aligned apertures of the front and the backing element clamp the front and the backing element over and around the central attachment area.
