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.

A composite wheel includes a rim, a connecting ring, a plurality of spokes and a flange all connected in sequence from the outside to the inside. One end of each spoke is provided with a thread, and the other end of each spoke is provided with a first mounting hole.

The invention relates to a composite wheel (200) including a hub (202), a rim (204) and a connection structure (206) connecting the hub (202) to the rim (204). The hub (202) has front (208) and rear (209) faces and is formed with one or more mounting formations (216) for, in use, receiving a fastener to mount the hub (202) to a mounting surface of a vehicle. Each mounting formation (216) includes a fastening region (218) recessed into the front face (208) of the hub (202) and includes a fastener aperture (212) defining a passage between the fastening region (218) and the rear face (209) of the hub. Each mounting formation (216) also includes a front-to-fastener ply (224) extending between a front region of the hub and the fastening region (218) for, in use, transferring load between the front region of the hub (202) and the fastening region (218).

A spoked bicycle wheel having a rim at least partially comprised of a composite material. The rim has at least one spoke attachment chamber with a plurality of spoke attachment holes. The wheel has a plurality of spokes coupled with the rim and a spoke attachment element partially inserted in a respective spoke attachment hole. The wheel includes a holding element that prevents the movement of said spoke attachment element along a radially outer direction. The spoke attachment element has a holding surface configured for abutment against the holding element.

A wheel rim assembly includes a rim defining a rim opening, a wheel disk disposed in the rim opening, a plurality of first fastening members fastening the wheel disk to the rim, and a plurality of second fastening members. The wheel disk includes a center disk defining a center bore that is coaxial with the rim, and a plurality of spokes interconnecting the center disk and the rim. The first fastening members fasten the spokes to the rim such that removal of the first fastening member permits separation of the spoke from the rim. The second fastening members fasten the spokes to the center disk such that removal of the second fastening member permits separation of the spoke from the center disk.

A lightweight wheel is provided, which includes a flange, a plurality of titanium alloy spokes and a carbon fiber rim, herein the flange is positioned at a middle part of the carbon fiber rim, the plurality of titanium alloy spokes are connected between the flange and the carbon fiber rim, and the plurality of titanium alloy spokes are uniformly distributed in pairs along the circumference; and one end of each of the titanium alloy spokes combined in pairs is fixed on the flange in a centralized mode, and another end is fixed separately at the carbon fiber rim, making the titanium alloy spokes combined in pairs a fan shape. An automobile is also provided.

The present invention provides a smart mobile vehicle comprising a vehicle body, a chassis, driving wheels, a battery module, a plurality of motors and a vehicle control unit. The chassis has a suspension system, a brake system and a steering system. The two driving wheels are composed of a plurality of circular units, and the driving wheels are embedded in two-wheel frames on two sides of the vehicle body. The battery module provides the smart mobile vehicle with driving power. The plurality of motors disposed between the two circular units or on a surface of any one of the circular units; wherein the motors are electrically connected to the battery module, and the torque and directional outputs of the motors is used to drive the rotation of the two driving wheels. The vehicle control unit is electrically connected to the motors and the battery module to transmit a monitoring signal.

A bicycle wheel rim made at least partially of a stratified composite material comprising structural fibers incorporated in a polymeric matrix. At least one opening, which passes through at least one first layer of composite material, is provided and at least one spoke attachment hole, which passes through at least one second layer of composite material, is also provided. The spoke attachment hole is completely contained within the opening in the first layer. A related manufacturing process is also described.

A composite material body (10) includes a first material layer (20) and a second material layer (30) overlapping the first material layer (20). The first material layer (20) and the second material layer (30) are wound to form a flexible and circular rod. Impact absorption is effectively improved and impact resisting strength is enhanced because energy-absorber or damping material or its composition is attached into the composite material body (10). Technical characteristics, effects and objects of this invention are achieved thereby.
