A rim for a vehicle wheel having an inner and an outer rim flange, an inner and an outer rim shoulder, a rim well with well base, inner well flank and an outer well flank, a transition section and an inner hump with a hump peak. The rim is having specific material thickness in the area of the transition section. In order to improve wheels in terms of weight minimization and noise development, the transition section comprises at least one stiffening section with a radially offset wall section, the maximum radial offset of which to the adjoining transition section is greater than the material thickness in the transition section. The stiffening section has a diameter, being equal or greater than the diameter on the well base and smaller than diameter of the hump peak.

Vehicle wheels and methods of making vehicle wheels are provided. A vehicle wheel comprises a generally annular first region, a second region, and a flange extension. The first region comprises an inner surface and an outer surface comprising a tire bead seat. The second region extends radially inwardly from the first region. The second region is configured to mount to a vehicle axle. The flange extension extends from the first region in a direction away from the second region. The flange extension comprises a first extension end integral with the first region, a second extension end, and an elongate portion intermediate the first extension end and the second extension end. The elongate portion comprising a first portion with a thickness less than a thickness of the second extension end.

A disk wheel, comprising a wheel rim (1) and a wheel spoke (2), the inner wall of the wheel rim outer edge (11) is matched with the first wheel spoke convex wall (9), the inner wall of the tire supporting wall (7) is attached to the strengthening wall (8), the groove (5b) is formed in the inner wall of the wheel rim round peak (5), the strengthening wall (8) is provided with the second wheel spoke convex wall (4) in interference fit to the groove (5b), and the groove (5b) is in interference fit to the second wheel spoke convex wall (4), so that the stability of axial matching between the wheel rim (1) and the wheel spoke (2) is guaranteed, and an axial stress, a circumferential stress and a radial stress of the disk wheel in the using process can be effectively addressed.

A rim section 18 is provided with e disk section 20 and is secured to a jig by patting the disk section 20 as the lower side. By allowing a groove section 40 l an engaging section) provided along a circumferential direction of the inner peripheral surface 21 of the rim section 18 to engage with a bent end section 48 of a reinforced member 14 attached from the upper side of the jig, the reinforced member 14 can be easily positioned on the inner peripheral surface 21 of the rim section 18.

A mounting portion of a disc includes a flat plate portion having a pressing surface to be pressed against a hub of an axle, and a plurality of nut support portions protruding from the flat plate portion to a side opposite to the pressing surface in an axial direction of the disc, and having an annular shape as viewed from the axial direction. A bolt hole is provided to penetrate the nut support portion in the axial direction. The nut support portion includes a bulging portion curving to bulge outward in a radial direction of the nut support portion, and a protruding portion disposed adjacent to the bulging portion in a circumferential direction of the nut support portion, and protruding inward in the radial direction of the nut support portion with respect to the bulging portion.

A wheel includes a rim and a wheel center interconnected to the rim. The wheel center includes at least one spoke extending from a wheel hub to the rim in a radial direction. The rim includes per the at least one spoke a first contact area and the at least one spoke includes at its outer end a second contact area which in a mounted position is aligned to the first contact area. The at least one spoke includes at least one hollow space extending in the radial direction of the spoke.

A composite rim for a bicycle wheel that has a wall of structural fibers incorporated in a thermosetting polymeric material and a plurality of spoke attachment seats. The composite material includes at least one layer of woven bi-directional fibers where some fibers are in a nominal direction substantially parallel to the circumferential direction of the rim and some fibers are substantially orthogonal to the circumferential direction of the rim.

A wheel hub for a utility vehicle includes a brake element abutment surface against which a brake element bears in an installed state, and a positive-locking arrangement which interacts in positively locking fashion, as viewed in a direction of rotation, with the brake element in the installed state, and/or a receiving region for a positive-locking arrangement which interacts in positively locking fashion, as viewed in a direction of rotation, with the brake element in the installed state.

An axle system includes an axle stub and a clamping unit, the axle stub being formed in a substantially rotationally symmetrical manner about a stub axis, the clamping unit in an assembled state transmitting a clamping force to the axle stub, the clamping unit and the axle stub in the assembled state being secured non-positively to prevent movement relative to one another.

A wheel of a vehicle, in particular a motor vehicle, has a rim, a hub portion, and at least two spokes connecting the hub portion to the rim. At least two adjoining spokes are connected to each other by at least one connecting web which is arranged in a space between the spokes, is not attached to the rim and the hub portion, and extends at least approximately in the circumferential direction of the wheel.
