A vehicle accessory mounting assembly for mounting a vehicle accessory to a vehicle fame assembly includes first and second support members adapted to couple to the frame assembly, a support assembly that includes first and second portions respectively slidably positionable along a length of the first and second support members and selectively engaging the first and second support members to lock the first and second portions at a selected position along the length of the first and second support members, a center portion having first and second portions, wherein the first and second ends of the center portion are adapted to couple with the first and second portions subsequent to the first and second portions being positioned along the length of the first and second portions, and a vehicle accessory arrangement coupled to the support assembly.

An aerodynamically optimized drag-reduction appartus and method for optimal minimization of the drag-induced resistive forces upon a terrestrial vehicle, where the drag-induced resistive moments on wheel surfaces pivoting about the stationary point of ground contact are reduced, and the vehicle propulsive forces needed to countervail the resistive forces on the wheel are reduced. The drag reduction apparatus includes: a streamlined fairing or wind deflector positioned on a vehicle to shield the faster moving upper wheel surfaces from headwinds; an engine exhaust pipe disposed on a vehicle whereby exhaust gases deflect headwinds to shield the faster moving upper wheel surfaces of an automotive wheel; an automotive spoked wheel having streamlined oval-shaped wheel spokes; a wheel assembly with a streamlined tailfin rotatably attached to a wheel spoke; a wheel with a tapered spoke having a thin aerodynamic profile near the rim and tapering to a round profile toward the central hub; and a tire having streamlined tread blocks arranged in an aerodynamic pattern.

A carcass ply is applied around an outer surface of a building drum according to an application diameter larger than the fitting diameter of a tyre. Coaxially engaged around each of the end flaps is an annular anchoring structure defining the fitting diameter. A pair of sidewalls is manufactured by laying of a continuous elongated element in the form of approached coils on the carcass sleeve. An outer sleeve, including at least one belt structure possibly associated with a tread band, is coaxially centered around the carcass sleeve. Through axial approaching of two halves forming the building drum, the carcass sleeve is shaped into a toroidal configuration to determine application of same against a radially internal surface of the outer sleeve.

A longitudinally tapered wheel spoke having a thin aerodynamic cross-sectional profile proximate to the wheel rim and tapering to a round profile toward the central hub, with the tapered section optimized to minimize drag against a combined headwind and crosswind impinging upon the primary vehicle-drag-inducing uppermost region of the wheel assembly.

A vehicle wheel weight for attachment to a wheel rim that includes a mass portion formed of nonlead material and a clip is presented. The clip has an extended portion for engaging the wheel rim and an attachment portion juxtaposed to the mass portion. In addition, an injection molded outer casing surrounds the mass portion. The mass portion and the attachment portion of the clip are embedded in the casing, but the extended portion of the clip extends outwardly from and is external to the casing.

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 hub assembly includes a retainer housing, a retaining member, a biasing element, and an occlusion. The retainer housing includes a wheel mounting sleeve and a pin sleeve. The wheel mounting sleeve includes an axle bore configured to receive an axle. The pin sleeve has a first end and a second end. The pin sleeve includes a conduit between the first end and the second end. The first end is in fluid communication with the axle bore. The retaining member and the biasing element are in the conduit. The retaining member is configured to engage a groove in an axle. The biasing element is configured to bias the retaining member towards the axle bore. The occlusion is proximate to the second end of the pin sleeve. The occlusion is configured to inhibit the retaining member from exiting the conduit at least prior to coupling the hub assembly to a wheel.

A minimal fairing apparatus minimally shielding the faster-moving drag-sensitive uppermost wheel surfaces from headwinds reduces overall vehicle drag. The apparatus includes various upper wheel fairings of FIGS. 1-6. Each fairing shields a primary vehicle-drag-inducing upper wheel surface from headwinds otherwise impinging thereon.

A wheel assembly including a cover portion permanently attached to a wheel. The wheel includes a wheel central hub portion, a wheel outer peripheral rim portion, a plurality of wheel spoke portions extending between the wheel central hub portion and the wheel outer peripheral rim portion, and a plurality of wheel turbine openings disposed between adjacent ones of the plurality of wheel spoke portions. A cover portion is configured to overlie a portion of the wheel portion. The cover portion is configured to overlie one or more of the wheel central hub portion; the plurality of wheel spoke portions, and the plurality of turbine openings or the wheel outer periphery. An adhesive is disposed between an outboard surface of the wheel and the inboard surface of the cover portion to permanently secure the cover portion to the wheel portion. When the cover portion is secured to the wheel, substantial portions of the plurality of wheel spokes, the wheel central hub, or wheel outer periphery remain exposed.
