摘要:
A connection between a face portion (12) and a hub portion (14) of a composite wheel (10). The hub portion (14) comprises a generally disc shaped hub plate (16), and the face portion (12) comprises a plurality of spokes (18). The connection comprises an annular hub ring (22) surrounding the hub plate (16), the hub ring (22) comprising a plurality of layers of reinforcement fibres extending in an at least generally circumferential direction about the hub ring (22). The connection also comprises a first plurality of layers of reinforcing fibres (24) extending in a generally radial direction R relative to an axis of rotation of the wheel (10), and along a front face of each spoke (18), across a front edge (26) and an inner annular surface (28) of the hub ring (22) and across a front face (30) of the hub plate (16); and a second plurality of layers of reinforcing fibres (32) extending in a generally radial direction R along a rear face (33) of each spoke (18), across a rear edge (34) of the hub ring (22) and across a rear face (36) of the hub plate (6). The connection further comprises a third plurality of layers of reinforcing fibres (36), the third plurality of layers (36) of reinforcing fibres overlaying the first and second (1) layers of reinforcing fibres (24, 32), the third plurality of layers of reinforcing fibres 36 extending in a direction between +30 degrees and +60 degrees to the radial direction R; and a fourth plurality of layers of reinforcing fibres (40), the fourth plurality of layers of reinforcing fibres (40) overlaying the first and second layers of reinforcing fibres (24, (32), the fourth plurality of layers of reinforcing fibres (40) extending in a direction (20) between -30 degrees and -60 degrees to the radial direction R.
摘要:
A centre-lock attachment arrangement attaching a 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 central attachment aperture through which the centre-lock fastener is inserted; a front element including an attachment aperture through which the centre-lock fastener is inserted; a backing element including an attachment aperture through which the centre-lock fastener is inserted; a plurality of fastener apertures annularly spaced around the attachment aperture of the composite wheel, the front element and the backing element; and a plurality of elongate fasteners configured to be received through the aligned apertures of the front element and the backing element which, in use, clamp the front element and the backing element over and around the central attachment area of the composite wheel.
摘要:
A connection (110) between a rim portion (102) and a face portion (104) of a composite wheel (100). The rim portion (102) comprises a first set of fibers (122). The face portion (104) comprises a second set of fibers (124). The connection (110) comprises a transition zone (120) in which the first set of fibers (122) and the second set of fibers (124) are arranged in a layered structure. Each layer (125A, 125B, 125C) of the layer structure includes a first section (127) including an arrangement of the first set of fibers (122), and a first connection end (128), and a second section (129) including an arrangement of the second set of fibers (124), and a second connection end (130). The first connection end (128) is arranged adjacent to or abutting the second connection end (130) forming a layer joint (132A, 132B, 132C). The layer joint (132A, 32B, 132C) of each adjoining layer (125A, 125B, 125C) is spaced apart in a stepped configuration.
