Wheel rim

A wheel for a vehicle, in particular a motorcycle or a motor scooter includes a hub region which has at least some portions made of a fiber-reinforced plastic material. The hub region includes a recess in which an insert for connecting the wheel to a vehicle axle is placed. An isolation element which galvanically isolates the insert from the hub region is arranged between the hub region and the insert.

A torsion spring may be configured as a torsion bar or a helical spring made of a spring wire made of fiber-composite material. The torsion spring may have a plurality of layers of fiber reinforcement that have been saturated with a matrix material, wherein the layers may have fibers that are tension-loaded and fibers that are compression-loaded. The at least one compression-loaded group may have a lower group stiffness than the tension-loaded group with the highest group stiffness. Methods for designing or making torsion springs made of fiber-composite material are also disclosed.

Disclosed are a connecting arrangement of a fiber composite component with a second component and a process for producing the arrangement. The second component comprises at least one flat section having one or more cut-outs which pass through the flat section. The flat section is arranged between at least two sublayers of the fiber composite component and at least one of the at least two sublayers with a layer thickness Scomprises one or more embossments which have an essentially even layer thickness Sand are molded into the one or more cut-outs.

Connecting arrangement for connecting a fiber composite component to a second component

A vehicle wheel comprising a wheel rim with a rim base made from fiber composite material and a wheel disc. The wheel disc is connected to the wheel rim by a connecting element which is guided through a passage of the rim base and is received in the wheel disc. The wheel rim comprises a connecting arrangement with at least one connecting element and a seal element which covers in a complete and hollow manner a part of one or more adjacent connecting arrangements that extends across the rim outer side of the rim base. A circumferential edge of the seal element is glued in air-tight manner to the rim well. Alternatively, the wheel rim comprises a connecting arrangement with a connecting element and a flexible sealing layer made from plastic and completely covers, by coating, a part of the connecting arrangement which extends over the rim outer side of the rim base. An edge region of the flexible seal layer is connected in an air-tight manner to the rim base.

Vehicle wheel having a connection of a wheel rim with rim base made from fiber composite material and a wheel disc

Disclosed is a vehicle wheel having a wheel rim and a wheel disc connected to an inner side of the wheel rim. The wheel disc is connected to the wheel rim by a connecting element which is guided through a through-hole of the rim base and inserted in the wheel disc. The through-hole is arranged in the tire seat of the rim base and the connecting element is joined substantially in the direction of the radial extension of the wheel disc which is associated to the tire seat on the inner side of the rim. In the method for producing the wheel the connection between wheel rim and wheel disc is produced in the region of the tire seat of the rim base, and, after the insertion of the connecting element into the wheel disc, a portion of the connecting element protruding the contour of the outer side of the rim of the tire seat is shaped so that the connecting element conforms to the contour of the outer side of the rim of the tire seat.
