The connection also comprises a first plurality of layers of reinforcing fibers (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 fibers (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 fibers (36), the third plurality of layers (36) of reinforcing fibers overlaying the first and second (1) layers of reinforcing fibers (24, 32), the third plurality of layers of reinforcing fibers 36 extending in a direction between +30 degrees and +60 degrees to the radial direction R; and a fourth plurality of layers of reinforcing fibers (40), the fourth plurality of layers of reinforcing fibers (40) overlaying the first and second layers of reinforcing fibers (24, (32), the fourth plurality of layers of reinforcing fibers (40) extending in a direction (20) between −30 degrees and −60 degrees to the radial direction R.
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.

摘要:
The present invention provides an attachment arrangement for use in attaching at least one composite wheel to a mount using an elongate fastener element and a fastening nut which can be fastened on the elongate fastener element. The attachment arrangement is used with a composite wheel that includes at least one attachment aperture through which the elongate fastener element is inserted. The attachment arrangement includes a fastening washer having a fastening aperture through which the elongate fastener element can be inserted when in use. The fastening aperture includes a radially central fastening axis. The fastening washer also has a base configured to face a surface of the composite wheel about the attachment aperture. In addition, the fastening washer has a fastening side facing substantially axially outwardly from the attachment aperture. The fastening side includes at least one engagement surface configured to operatively engage a complementary portion of the fastening nut when the fastening nut is assembled on the elongate fastener element. The fastening arrangement also includes a sleeve which extends axially relative to the fastening axis outwardly from the base about the fastening aperture. The sleeve is configured to extend into the attachment aperture of the composite wheel. The sleeve also includes a distal end configured to be received in a complementary shaped sleeve aperture located in the mount or in an element located adjacent the mount.
