This non-pneumatic tire is provided with a tread ring, a wheel which is arranged radially inside of the tread ring, and spokes which are interposed between the tread ring and the wheel. Further, the wheel has a disc part to which the vehicle shaft is linked, and a rim part which is connected on the inner peripheral side to the disc part and is joined on the outer peripheral side to the spokes. In this configuration, the average thickness (T1) of the disc part is set to be less than the average thickness (T2) of the rim part. In other words, the relation T1<T2 holds.

A wheel for vehicles in which the front flange is provided with an annular seat which accommodates at least partly the terminal end of the rim in order to form an external shoulder profile. The rim includes a substantially cylindrically extended central body part; an internal shoulder profile arranged at a first end of said body and is configured to receive an internal edge of a tire; and a terminal end arranged at a second and opposite end of said body. The disc includes a hub portion configured to be connected to a vehicle axle, a perimetric front flange and a connecting portion which connects the hub portion to the front flange. The front-flange is provided with an annular seat in which the terminal end of the rim is accommodated at least partially in order to form an external shoulder profile

A wheel rim including a flange profile on a tire side of an open end flange of the wheel rim, the flange profile defined by the equation:

[00001]$y_1=\left(\mathrm{aTheta}.Math..Math.1+\frac{1}{{\left(1+\mathrm{Exp}\left(\mathrm{aTheta}.Math..Math.3+\mathrm{aTheta}.Math..Math.4.Math.X_1\right)\right)}^{\mathrm{aTheta}.Math..Math.5}}\right).Math.\mathrm{aTheta}.Math..Math.2$

wherein, for 0X.sub.11, aTheta1 is between 1.004 to 0.974, aTheta2 is between1.049 to 1.0182, aTheta3 is between 3.601 to 2.760, aTheta4 is between 18.791 to 25.965, and aTheta5 is between 0.185 to 0.277.

Disclosed is a vehicle support device comprising a polygonal surface which may be affixed to a front edge of an at least one circumferential plate (110) or to a midline of an at least one circumferential plate (110). The polygonal surface (105) may be a pentagon polygon having five sides, a hexagon polygon having six sides, an octagon polygon having eight sides, or any polygonal shape. The polygonal front surface may have an at least one asymmetrical side. The polygonal front surface (105) may have a plurality of lug bolt supports (120), which may have five lug bolt supports (120), seven lug bolt supports (120), eight lug bolt supports (120), or twelve lug bolt supports (120). The vehicle support device may have an axle support centerline (125), a vehicle support device centerline (130), and an non-zero centerline offset (135) between the axle support centerline (125) and the vehicle support centerline (130) to provide for offset alignment of the vehicle support device in a vehicle wheel well. The vehicle support device may be used to support any wheeled automobile, trailer or tractor, to provide levelness and stability of the vehicle, prevent UV and time or gravity-caused degradation of the tires, and extend the life of the tires, and on other vehicles with modification. For most automobiles, trailers, and tractors, the vehicle support device may replace one or more of the tires and wheels on an axle to securely and solidly support the vehicle on ground or a on concrete pad.

The application relates to a wheel hub for vehicle, which comprises a flange, a rim, a spoke, a central hole, and bolt bores distributed around the central hole. According to the disclosure, the flange on the wheel front side is affixed with an extension part comprising a radial extension magnitude extending to the outer periphery of the wheel hub and an axial extension magnitude extending to the wheel front side, the extension part comprises a plurality of sections circumferentially distributed along the flange, so as to form on the wheel front side an envelope circle having a diameter size increased by twice the radial extension magnitude. The present disclosure further satisfies the additional needs of the user with respect to the overall design of the wheel.

A disc portion and a rim portion of a tire wheel are integrally formed simultaneously, with a resonance pipe formed between the disc and rim portions, by inserting a molten metal into a space formed by a mold combined with the resonance pipe by core pins.

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.

The invention relates to a manufacturing method and a structure of a wheel rim. The manufacturing method mainly comprises the steps of forming a rim body made of a carbon fiber material in a cavity of a molding die; forming a rim assembly by extruding a metal material and assembling the rim assembly to the rim body; and forming a rim coating by tightly encapsulating a carbon fiber material on a surface of the rim body assembled with the rim assembly.
