Spokes of a wheel contain: a wheel rim, a hub, multiple screwing segments, and multiple screw elements. The respective spoke is made of chrome molybdenum (CrMo), and the respective spoke includes a through hole passing therethrough so as to form a seamless alloy steel pipe. The respective spoke includes a first connection segment and a second connection segment, the first connection segment has a first threaded section, and the second connection segment has a second threaded section so that the first threaded section is screwed with the respective screw element of the hub. The respective screw element of the hub has an orifice, such that the first threaded section is inserted through the orifice to screw with the respective screw element on an inner wall of the hub, and the second threaded section is screwed with the respective screwing segment of the wheel rim.

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 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.

A lightweight wheel with high strength flexible spokes of the present invention, includes a rim and hub, and a plurality of lightweight, flexible and resilient spokes between the rim and hub made of fibrous material that causes the spokes to be both lighter in weight and stronger than comparable steel spokes. The wheel includes a nipple within the rim that receives the high strength spoke and allows for flexibility in adapting the spoke to wheels having differing shapes and sizes.

The present invention discloses a carbon fiber spoke and a manufacturing method thereof. The carbon fiber spoke includes a spoke body made of carbon fiber, a screw bushing that is fit and connected with rim and a nut cap bushing that is fit and connected with the hub. Two end parts of the spoke body are provided with solid joints. The outside surface of the solid joint is provided with a first tapered section. The screw bushing and the nut cap bushing are provided with penetrable mounting holes. The hole wall surrounding the mounting hole is provided with a second tapered section. The mounting hole of the screw bushing and the mounting hole of the nut cap bushing are respectively fixed to the two solid joints; the second tapered section of the mounting hole and the first tapered section of the solid joint are fit and connected together.

An exemplary spoke for a non-pneumatic wheel. The spoke can be manufactured with a reinforcement structure having reinforcement elements and one or more layers of material. The spoke can also be provided in various shapes and configurations. The spoke includes anchors that allow the spoke to be more readily incorporated into, or removed from, a non-pneumatic wheel. More particularly, the anchors also allow the spoke to be joined as one-piece with the non-pneumatic wheel or releasably connected on one or both ends with the non-pneumatic wheel.

In a spoke wheel that includes: a rim; a hub; and a plurality of spokes connecting the rim with the hub, the spokes each having an end portion connected with a connection portion disposed at a lateral surface portion on an outside in a width direction of the rim, the rim includes a raised portion that is raised from the connection portion to the outside in the width direction.
