A wheel structure including a high strength polymer encapsulates a portion of the lug structure dish section. Rim ring(s) are included in the wheel structure and are preferably made of a fiber reinforced high strength polymer.

An electrical passenger car, the car including: an electrically driven motor; and wheels, where the wheels include a first wheel, a second wheel, a third wheel, and a fourth wheel, where the first wheel and the second wheel have a radius 20 percent larger than the third wheel and the fourth wheel, where the electrical passenger car includes a total weight, where the electrical passenger car includes a center of gravity designed so that greater than 50% of said total weight will be over the first wheel and the second wheel, and where the electrical passenger car is designed to travel for a greater distance for the same axial to wheel friction energy loss than a passenger car having wheels of a smaller radius.

A multi-width dual wheel arrangement and method utilize a dual wheel spacer and a clamping disk for selectively mounting a dual wheel having a rim to a first wheel at a desired axial spacing of the dual wheel from the first wheel along a rolling axis of the dual and first wheels. The clamping ring is positioned outboard of the rim to clamp the rim between the clamping ring and the spacer for positioning the dual wheel at a first axial spacing from the first wheel along the rolling axis. The clamping ring is positioned inboard between the rim of the dual wheel and the dual wheel spacer for positioning the dual wheel at a second axial spacing from the first wheel. A third axial spacing is provided by configuring the rim to have a convex surface that may be electively positioned facing toward or away from the first wheel.

Wheels adapted to roll on and across surfaces of fields, for example, as part of irrigation systems of types used in agricultural applications. Such a wheel has an axis of rotation, a center portion comprising a central hub concentrically disposed on the axis of the wheel and multiple spokes radiating from the central hub, and a tread portion circumscribing the center portion. A radially outermost extent of each spoke terminates at a spade that is oriented parallel to the axis of the wheel. The tread portion includes tread plates, each located between and attached to adjacent pairs of the spokes. The spades protrude radially outward between and beyond adjacent pairs of the tread plates.

A wheel for a motor vehicle comprises a rim having an outer radius and a wheel spider including a radially inner hub and a plurality of spokes extending from said hub towards said rim. At least one through-hole extends, with respect to the wheel axis, in a circumferential direction through at least one of said spokes. A radially outer edge of said through-hole or of an outermost of said through-holes is located at maximum at 75%, preferably at maximum at , of said outer radius of the rim measured at a wheel spider side of the rim.

A spare wheel assembly comprising a tire and a rim to which the tire is attached is disclosed. The rim includes a center mounting plate having a center bore, inner and outer opposed flanges, and a disk between the center bore and the flanges. The disk includes a pair of elongated, curved slots formed on opposite sides of the center bore. Each of the slots is an ergonomically-formed hand hold for receiving fingers of an operator's hand. The inner and outer opposed flanges of the rim define perimeters of the rim between which the tire is held. The curved slots are concentric with respect to the perimeter of the outer flange and with respect to the center bore. A centerline is formed radially through the assembly. The disk is positioned on one side of the centerline and the mounting plate is positioned on the other side of the centerline.

A vehicle wheel for commercial vehicles, having a fastening device for an aerodynamic wheel disc cover. In order to enable secure and easy fastening of the disc cover, the fastening device comprises several fastening holes arranged in the hub connection flange, with at least one fastening hole consisting of a through hole having a smaller diameter on the front side of the wheel than on a rear side of the hub connection flange and forming an abutment for a detachable retaining means acting by form fit, and/or wherein at least one fastening hole consists of a through hole provided with an internal thread for screwing in a fastening screw as a retaining means, and/or that the centre hole has an inner circle edge comprising a constriction which forms an abutment for a cover side arranged retaining means acting by form fit.

A stable, low-weight wheel which is particularly suitable for high system-weight bicycles, such as electrically powered bicycles and cargo bikes, includes a hub, at least three solid-body spokes disposed rotationally symmetrical to the wheel axis, and a rim. The body of the hub, spokes and rim is made in one piece by injection molding of a glass-fiber reinforced thermoplastic. The spokes have an S-shaped cross-section with an opening angle which increases in the direction of the rim, taper from the rim towards the hub in a central cross-section of the wheel, and taper from the hub towards the rim in a wheel cross-section running through the center of least one spoke. A method for producing the wheel is also provided.

Vehicle wheel comprising a rim part and a disc part formed from a one-piece sheet metal blank and including a central portion with bolt holes and a plurality of radially extending spoke arrangements merging into a disc edge delimiting together with the spoke arrangements ventilation apertures which extend over the region between the edge webs and the disc edge. In order to create steel wheels with four-hole fixing in which high strength and stiffness are achieved the number of spoke arrangements and of bolt holes is four and these are in each case arranged mirror-symmetrically with respect to a common radial line, with the width of each spoke arrangement narrowing radially towards the outside and each ventilation aperture extending in the circumferential direction over an arc length of more than ? of the circumference of the disc part. Further, each ventilation aperture is having on a radial line a maximum radial clear width which is equal to or preferably greater than the radial width of the metal portion of the disc part on the same radial line.

A wheel disc for a disc wheel, especially for utility vehicles; with an essentially radially extending hub fitting flange and an essentially cylindrical disc edge which can be joined to a wheel rim, and with a transition region extending between the hub fitting flange and the disc edge, wherein the transition region is subdivided into at least five segments (A.sub.I to V) passing into each other or into the hub fitting flange or the disc edge, each of which has an outer end situated closer to the hub fitting flange and an inner end situated closer to the disc edge, wherein neighboring segments have curvatures with different directions and variable material thickness, with the ratios of the material thicknesses and the ratio of their lengths to heights are chosen as follows: TABLE-US-00001 Ratio of Material Ratio of Length in thickness at axial inner end (di) to direction (L.sub.a) to Material thickness at Height in radial outer end (da) direction (H.sub.r) First segment A.sub.I 0.45-0.7 0.9-1.1 (between the hub fitting flange and segment A.sub.II) Second segment A.sub.II 0.7-1.0 1.6-1.9 (between A.sub.I and A.sub.III) Third segment A.sub.III 0.9-1.25 2.5-2.8 (between A.sub.II and A.sub.IV) Fourth segment A.sub.IV 0.9-1.25 2.8-3.1 (between A.sub.III and A.sub.V) Fifth segment A.sub.V 0.7-1.15 7.0-6.8 (between A.sub.IV and the disc edge).
