Abstract
The disclosure is directed to a wheel having a rim that is at least partially made from several layers of fiber-reinforced plastic, and a wheel center having multiple spokes extending from a wheel hub, which constitutes an axis of rotation, to the rim in a radial direction. According to the disclosure the rim comprises a rim well extending in transversal direction between an inboard flange and an outboard flange suitable to receive a tire to be mounted thereon. The wheel includes a circumferential collar that extends from the outboard flange radially inwards towards the axis of rotation and that has an outboard collar face that constitutes an aerodynamic surface.
Claims38
A wheel comprising:
- a. a rim that is at least partially made from several layers of fiber-reinforced plastic, and
- b. a wheel center comprising multiple spokes extending from a wheel hub, which constitutes an axis of rotation, to the rim in a radial direction, and wherein the rim comprises a rim well extending in transversal direction between an inboard flange and an outboard flange suitable to receive a tire to be mounted thereon, and wherein
- c. the wheel comprises a circumferential collar that extends from the outboard flange radially inwards towards the axis of rotation and that has an outboard collar face that constitutes an aerodynamic surface.
A fastening arrangement (700) for use in fastening a wheel (1) with a wheel center (100) made at least partially from a fiber-reinforced plastic to a vehicle hub by means of at least one elongate fastener means, wherein
- a. the wheel center (100) comprises at least one fastening aperture (720) having at least one inner engagement surface (721) and a fastening axis (Af) wherein
- b. the fastening arrangement (700) comprises,
- i. at least one bushing arrangement (710) having at least one inner bushing opening (711) through which the at least one elongate fastener is inserted for fastening of the wheel (1) and
- ii. the bushing arrangement (710) configured to extend along the fastening axis (Af) into the fastening aperture (720) for fastening of the wheel (1) and
- iii. the bushing arrangement (711) comprising at least one outer engagement surface (712) configured to face the at least one inner engagement surface (721) when the bushing arrangement (710) is arranged in the fastening aperture (720) and wherein
- iv. the at least one outer engagement surface (712) is configured to apply an expanding force (F) on the inner engagement surface (721) when the bushing arrangement (710) is inserted into the fastening aperture (720), thereby widening at least a portion of the fastening aperture (720).
