An aerodynamic bicycle rim, the bicycle rim comprising a circumferential clincher portion adapted to seat a clincher bicycle tire, a nose a set of sidewalls, each sidewall extending radially from the nose to a respective circumferential outer edge to form a rim body having a maximum rim body width that is greater than a maximum width of the clincher bicycle tire and spaced radially inward of the clincher portion and radially outward from a centerline of the rim body. The aerodynamic bicycle rim seats the clincher bicycle tire to form an asymmetrical cross-sectional shape in which the widest part of the rim body is spaced from a centerline of the asymmetrical cross-sectional shape and there is a tangent line tangent to the clincher bicycle tire and a sidewall of the set of sidewalls, the tangent line tangent to the sidewall radially inward from the respective circumferential outer edge.

A wheel for vehicles is provided. The wheel has a rim of sheet metal having on its axially outer side an outer flange, an outer bead seat, an outer retaining hump, and a rim well connected to the outer bead seat through the outer retaining hump. The wheel has a disc of sheet metal having a cover part and a connection part axially protruding from the cover part. The connection part of the disc is fixed to a radially inner surface of the rim. At least one formation of additive material is formed on at least one of the rim and the disc, the at least one formation defining a steep thickness change with respect to a surrounding region of sheet metal.

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.

A system and method use a magnetic cancellation loop to control magnetic wheel adhesion. The wheel has an inner annular disc composed of a non-magnetic material with apertures to retain ferromagnetic structures and magnets, and an outer annular discs composed of a ferromagnetic material and are disposed on either side of the inner annular disc. Each outer annular disc has a non-magnetic isolator ring having curves extending in a serpentine manner. In a first configuration, the curves isolate the ferromagnetic structures from the magnets, thereby generating a first magnetic flux to increase the adhesion of the wheel to the ferromagnetic surface. In a second configuration, at least one outer annular disc is rotated to dispose the curves to allow magnetic interaction between the ferromagnetic structures and magnets, thereby generating a second magnetic to decrease the adhesion of the wheel to the ferromagnetic surface. The method implements the system.

A heat shield for an aircraft wheel assembly is made of a heat shield material evenly distributed across the heat shield along both the circumferential and the axial directions. The heat shield material has a high thermal conductivity greater than 30 W/mK. In various embodiments, the thermal conductivity is greater than 85 W/mK. In this manner, thermal flux is maximized throughout the heat shield to distribute heat evenly across the heat shield in both circumferential and axial directions.

A spinner wheel assembly for a luggage case is provided. The wheel assembly may include a housing, a support strut rotatably coupled to the housing about a spinner axis, and a plurality of wheels each rotatably coupled to the support strut about a wheel axis. Each wheel may rotate in a plane positioned at an angle to at least one other wheel. Each wheel may be coupled to the support strut in a spaced relationship thereto.

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).

An aerodynamic bicycle rim comprising: a circumferential outer portion comprising a circumferential outer surface, the circumferential outer portion adapted to seat a bicycle tire; a nose; and a set of sidewalls, each sidewall extending radially from the nose of the aerodynamic bicycle rim to a corresponding transition to the circumferential outer surface to form a rim body having a maximum rim body width that is greater than a maximum width of the bicycle tire.
