A non-metallic rim for a wheel which may be used for motorised vehicles. The rim has a barrel, a first flange, a second flange, a first bead seat, a second beat seat and a primary structural component. The primary structural component extends into at least the first flange and the barrel, and the primary structural component is capable of bearing the majority of the radial and/or lateral load that is borne by the rim during usage. Additionally, the rim has at least a portion of the first bead seat spaced apart from the primary structural component and/or has a protective insert in between the outer face of the first flange and the primary structural component.

A wheel includes a main hub portion having outer and inner portions, the inner portion being spaced from the outer portion by a main hub sidewall; a ring portion configured to engage the main hub portion so as to enclose the outer portion and the inner portion and create an enclosed void; and an exterior covering surrounding at least part of the main hub portion and the ring portion at the enclosed void. A method of forming a wheel includes forming a main hub portion having an outer portion and an inner portion; forming a ring portion configured to engage the main hub portion so as to enclose the outer portion and the inner portion and create an enclosed void; assembling the main hub portion and the ring portion into an assembled hub; and overmolding an exterior covering surrounding at least part of the main hub and ring portions.

The invention relates to a manufacturing method and a structure of a wheel rim. The manufacturing method mainly comprises the steps of forming a rim body made of a carbon fiber material in a cavity of a molding die; forming a rim assembly by extruding a metal material and assembling the rim assembly to the rim body; and forming a rim coating by tightly encapsulating a carbon fiber material on a surface of the rim body assembled with the rim assembly.

A rim for a bicycle wheel includes a radially inner portion disposed along an inner circumference of the rim. The rim also includes a first sidewall and a second sidewall spaced apart from the first sidewall. The first sidewall and the second sidewall extend radially outward from the radially inner portion. The first sidewall includes a layer of a composite material. The layer of the composite material includes fabric plies of the composite material that are shaped as strips. The composite material includes a matrix of a polymer-based material and fibers of a reinforcing material. The strips include a first strip and a second strip. The second strip is adjacent to the first strip within the layer of the composite material. The second strip is nonparallel to the first strip.

A rim for a bicycle wheel includes a radially inner portion disposed along an inner circumference of the rim, a first sidewall, and a second sidewall spaced apart form the first sidewall. The first sidewall and the second sidewall extend radially outward from the radially inner portion. The radially inner portion includes a stack of strips of material. The stack of strips includes a plurality of strips and a hole through the plurality of strips. The plurality of strips are nonparallel to each other. The plurality of strips are positioned about the hole through the plurality of strips.

A hybrid connection element, in particular a bearing outer element of a wheel bearing, includes a core part made of steel and a reinforcement part made of plastic. The reinforcement part at least partially encases the core part. The core part includes a hollow cylindrical bearing unit extending in an axial direction and a flange extending in a radial direction. The reinforcement part includes at least one reinforcement rib which transmits force between the bearing unit and the flange of the core part.

A wheel for a non-motorized vehicle (e.g., a shopping cart) can include a housing assembly and a tread assembly. The housing assembly can be configured to sealingly house electronics or other components. The tread assembly can removably mate with the housing assembly such that the electronics or other components remain closed and/or sealed within the housing assembly when the tread assembly is mated or unmated with the housing assembly.

An electromotive drive wheel arrangement for a motor vehicle comprises: a stator that is connectable to a wheel carrier in a rotationally fixed manner and that supports a coil-like winding, and a rotor rotatably supported relative to the stator and configured in the form of a wheel rim and arranged at least partially radially outside around the stator, wherein the wheel rim comprises a rim base and a rim star, connected to each other, wherein the rim base includes at least partially a fiber-reinforced plastic, and in the rim base several magnets are integrated in a material connection, and that the rim star includes at least partially a metal material.

The stack of strips includes a plurality of strips and a hole through the plurality of strips. The plurality of strips are nonparallel to each other. The plurality of strips are positioned about the hole through the plurality of strips.

A steering knuckle comprising a bearing connection interface (formed by a sleeve element) for connecting a wheel bearing to the steering knuckle and further connection interfaces (formed by a bracket for connection of a ball joint) for connecting the steering knuckle to an upper and lower vehicle suspension control arm. A sleeve element bore is adapted to one of receive a wheel bearing outer ring or serve as the outer ring. The sleeve element and the bracket are joined by a composite body comprising a fiber-reinforced material. The fiber-reinforced material comprises a long fiber molding compound is overmolded to a first (sleeve element) joining surface and to a second (bracket) joining surface. The first joining surface is a radially outer surface thereof. The long-fiber molding compound flows into a recessed portion of the first joining surface for mechanically locking the sleeve element to the composite body in an axial direction.
