Abstract: A wheel formed by the assembly of a disc comprising a hub bearing surface, a transition zone and a radially outer edge, and of a rim with at least a first laminated composite structure formed of at least one fabric of long fibers which are oriented in two distinct directions and impregnated by a cross-linked resin, the radially outer surface of which corresponds to the radially outer surface of the rim or to part thereof, at least a second laminated composite structure formed of at least one fabric of long fibers which are oriented in two distinct directions and impregnated by a cross-linked resin, the radially outer surface of which corresponds to the radially inner surface of the rim or to part thereof, and at least a circumferential weight-reduction structure formed of a material of low density, arranged radially between the first and second laminated composite structures.

Abstract: Wheel rim whose radially exterior geometry comprises an outer and an inner rim seat, a bearing surface formed essentially as a cylinder of revolution to receive a tire tread support ring, and whose radially interior geometry does not increase between the said mounting groove and the zone of connection to a wheel disc, which is made up by assembling a first, metallic structure constituting the radially interior geometry of the said rim and at least part of the radially exterior geometry of the said rim; and a second structure designed to constitute the said bearing surface radially on the outside, wherein the said second structure consists of an annular support element comprising at least one essentially axial opening and which comes in contact with the radially outer wall of the said first, metallic structure.
