The invention relates to a vehicle rim having a rim body made from a fiber composite material, the rim body having two rim flange areas and a rim bed area connecting the two rim flange areas, and at least one rim flange area being reinforced by at least one fiber bundle and this at least one fiber bundle being surrounded by a compression wrap. The invention also relates to a vehicle wheel with the vehicle rim and to a production method for the vehicle rim.

A wheel and a rim with weight reduction sockets are provided. The rim includes an inner flange, a middle portion and an outer flange, the inner flange, middle portion and outer flange are all annular and are connected end to end to form a cylindrical rim, in which the middle portion of the rim includes weight reduction sockets; and the weight reduction sockets are of regular hexagons, and are arranged adjacently on the outer side of the middle portion of the rim in the shape of a honeycomb. The weight of the hub is reduced by designing the weight reduction sockets in a specific shape for the outer rim of the hub and selecting the size of the weight reduction sockets.

A wheel rim comprising a peripheral structure for receiving a tire, and a central structure for coupling with a hub of the vehicle. The peripheral structure comprises, for each side of the wheel rim, a peripheral flange, a connecting wall on which the bead of the tire rests, and a connecting part. The peripheral structure includes a central well. The connecting part comprises a first curved region which joins the central well, and a second curved region between the first curved region and the connecting wall. The second curved region has a convex profile from the side of the wheel rim with the tire, and comprises a first curved surface joined to the connecting wall with a first radius of curvature, and a second curved surface between the first curved surface and the first curved region, with a second radius of curvature different from the first radius of curvature.

Adapter for a rolling assembly, of axis of rotation X-X′, comprising a tire (2), a rim (3), and an adapter (100), said adapter comprising an axially inner end (10), an axially outer end (11) and a body (12), wherein said axially outer end comprises an outer reinforcing element (15) which is a structure substantially of revolution about the axis X-X′ comprising a plurality of windings of at least one wire that are arranged axially beside one another over several layers radially superposed on one another. The section of the outer reinforcement (15) has a ratio of moments of inertia Ix/Iy of greater than 1.3 for an axial width of between 6 and 9 mm, where Ix is the moment of inertia around a first axis passing through its centre of gravity and parallel to the axis of rotation X-X′, and Iy is the moment of inertia around a second axis passing through its centre of gravity and perpendicular to the first axis.
