A bicycle wheel hub that includes a hub shell having a first end and a second end. The bicycle wheel hub also includes a first flange adjacent the first end and configured for the attachment of a first plurality of spokes, and a second flange adjacent the second end configured for the attachment of a second plurality of spokes.

A materials handling equipment has blades of a lifting fork wherein each of the blades engages a blade wheel that moves between a retracted position when the blade is lowered and an extended position when the blade is raised to lift and support a load. The blade wheels have a plurality of tires linearly aligned on a common axis, the tires each having a circular circumference and a sinusoidally varying peripheral surface. The sinusoidally varying peripheral surfaces have relative peaks and valleys uniformly spaced around the circular circumference wherein the peaks and valleys are mutually nested.

The present invention provides a new style or design for a steel wheel 200 in passenger vehicle with improvement in performance and aesthetics. In the new design of the steel wheel 200, a vent-hole outer region 214 is folded 206 inwardly to form two ends, wherein one end is welded to an outboard bead seat 212 of the steel wheel rim and the other end welded to a portion of an outboard flange portion 204. The inward folding 206 of the vent hole outer region 214 increases the vent-hole 205 area and thereby improves better air flow and cooling of a brake drum. The passenger vehicle steel wheel 200 design enables for spot welding throughout the circumference of the rim-disc contact surface for better contact and higher load/moment transfer. Further, the passenger vehicle steel wheel 200 may utilize an existing rim without any special machining or modification.

A wheel cover unit for rear wheels of trucks or buses includes: a wheel cover, two attaching members and a cover. The wheel cover is provided with an inner concave portion having a central hole. The inner edge of the central hole is vertically and backwardly provided with a hole ring having two corresponding pairs of slots. Two pairs of lock tabs are extended from the two pairs of slots respectively to the central hole. Each attaching member is provided with a connecting element and an engaging element. The connecting element is formed with a connecting portion for passing through the bolts of the wheel. The engaging element is formed with two connecting pieces. Each connecting piece is locked with the lock tab by a screwed element, so as to assemble the wheel cover to the rear wheel of the truck or bus.

A wheel cover unit for front wheels of trucks or buses includes a wheel cover, two attaching members and a cover. The wheel cover is provided with an outer convex platform having a central hole, and the periphery of the central hole is annularly provided with a plurality of nut convex covers and a plurality of through holes. The inner edge of the central hole is vertically and backwardly provided with a hole ring having corresponding two pairs of slots, wherein each slot extends to the central hole with a lock tab. Each attaching member is provided with a connecting portion and two connecting pieces. The connecting portion is locked with the bolt of the wheel and the connecting piece is locked with the lock tab via a screwed element, so as to assemble the wheel cover to the front wheel of the truck or bus.

A wheel rim having a central axis and comprising a central hub configured to be fixed to a suspension of a vehicle; a peripheral ring, which is arranged around the hub with a predetermined radial distance from the hub itself and is configured to receive a tire of the vehicle on a radially outermost surface thereof; a plurality of spokes equally spaced angularly from one another around the axis and connecting the peripheral ring to the hub; and at least one projection protruding in a cantilever fashion towards the hub, starting from a radially innermost surface of the peripheral ring, opposite to the radially outermost surface, and defining an airfoil configured to generate, in use, during the forward travel of the vehicle, a channelling of the air towards the outside of the wheel rim.

A mounting wheel (3) for a motor vehicle comprising an internal surface (2) and an external surface (4), the internal surface (2) not being visible when the mounting wheel (3) is mounted on the motor vehicle, and at least one fixing element (7) configured to attach the mounting wheel (3) to the motor vehicle. The fixing element (7) is arranged on the internal surface (2) of the mounting wheel (3) so that the fixing element (7) is not visible when the mounting wheel (3) is mounted on the motor vehicle.

An aerodynamic tailfin rotatably attached to a shaft-shaped member disposed on a vehicle. The tailfin swivels about the round shaft-shaped member for reduced drag in response to winds varying in direction impinging thereon.

A vehicle wheel structure comprising: a road wheel; a wheel mounting whereby the wheel is mounted to the body of the vehicle, the mounting structure comprising a wheel bearing by which the wheel can revolve about a wheel axis with respect to the body of the vehicle; a wheel cover attached to the wheel by a wheel cover bearing by which the wheel can revolve about the wheel axis with respect to the wheel cover; and a link coupled between (i) the cover and (ii) one of the mounting structure and the vehicle body for resisting rotation of the wheel cover with respect to the wheel mounting about the wheel axis.

A wheel for use with a bicycle includes a hub for mounting the wheel to a bicycle, a rim about which a tire is mountable, and a plurality of spokes that extend between the hub and the rim. The rim and/or one or more of the spokes have a leading and/or trailing edge, at least part of which has an undulating configuration.
