A wheel includes a rim having a rim well and rim flanges, a hub, and at least three spoke elements. Each spoke element forms at least one spoke between the hub and the rim. The spoke elements are fastened to an inside of the rim in a form-closed manner or a form-closed and bonded manner. In the hub region, the spoke elements are supported on each other in a circumferential direction at abutting surfaces designed therefor. A method for producing the wheel is provided.

A composite wheel structure includes a single continuous fiber reinforcement layer extending axially between inner and outer ends of the wheel structure. The single fiber reinforcement layer is impregnated with different matrix materials at different axial portions of the reinforcement layer to account for specific locations where high strength or high temperature performance is needed, with other portions having different matrix materials where low temperature performance and/or low strength is sufficient. The matrix materials may be provided as separate resin films that are applied side-by-side on the single reinforcement layer, or they may be provided on a single resin film. The matrix materials may be applied to the reinforcement layer in a direct coating process. The reinforcement layer may be prepregged with the matrix materials prior to a wheel layup process, or the reinforcement layer and matrix materials may be consolidated by resin film infusion during the wheel layup process.

Methods for fabricating composite wheel assemblies are described, as well as the composite wheel assemblies being fabricated. The composite wheel assemblies may include multiple formed components that are joined together at one or multiple locations within the wheel assemblies, or may be fabricated as a castable wheel. The composite wheel assemblies may be fabricated from reinforced plastic and/or a metal.

The invention refers to a vehicle rim (1) with a rim body (2) made of fiber composite material, comprising a first subpreform (3) at a first axial end and a third subpreform (5) at the opposite second axial end, wherein a second subpreform (4) is arranged between the first subpreform (3) and the third subpreform (5), wherein the second subpreform (3) engages into a front connecting cavity (6) formed by the first subpreform (3) as well as also into a rear connecting cavity (7) being formed by the third subpreform (5). The invention also refers to a method for the production of a vehicle rim (1) with a rim body (2) made of fiber composite material, wherein an NCF material (19) comprising carbon fibers, glass fibers and/or aramid fibers is created respectively for the formation of a first subpreform (3) for a first axial end of the rim body (2) and of a third subpreform (5) for the opposite axial end of the rim body (2) with a connecting cavity (6, 7), respectively, wherein a second subpreform (4) made of a same or a similar NCF material (19) is inserted into the connecting cavity (6 and/or 7) and is fixed thereat.

A longitudinally and radially formable wing tip lagging that can be formed to match non-linear wing tip profiles. The longitudinally and radially formable wing tip lagging serves as a wear surface that can be replaced as it is worn rather than wearing down the ferrous or non-ferrous wing tips permanently affixed to the outermost positions of the wing pulley. The wing tip lagging includes a backing plate and a sacrificial stratum. The backing plate is the primary structural component and it includes a plurality of bending features that facilitate both longitudinal and radial forming of the wing tip lagging. The bending features may include a plurality of notches or slots formed along the backing plate. For example, the notches may be arranged in a regular repeating pattern along the length of the backing plate.

A wheel includes a rim having a rim well and rim flanges, a hub, and at least three spoke elements. Each spoke element forms at least one spoke between the hub and the rim. The spoke elements are fastened to an inside of the rim in a form-closed manner or a form-closed and bonded manner. In the hub region, the spoke elements are supported on each other in a circumferential direction at abutting surfaces designed therefor. A method for producing the wheel is provided.

The invention relates to a method for manufacturing a pulley device for a tension roller or a roller of a transmission element providing a pulley, at least two rolling-element bearings and a sleeve, the rolling-element bearings being assembled adjacently on the sleeve before the pulley is formed by injecting material onto the rolling-element bearings.
