An apertured article, insertion article and associated systems. The apertured article having an aperture, which has an aperture periphery, the aperture periphery having an aperture inner periphery and spaced aperture protrusions that extend radially outwardly from the aperture inner periphery to an aperture outer periphery. The aperture outer periphery is defined by distal edges of the spaced aperture protrusions. The aperture inner periphery is positioned along the circumference of an inner aperture reference circle, the inner aperture reference circle inscribing the aperture periphery, and the aperture outer periphery is positioned along the circumference of an outer aperture reference circle. As viewed along a radial line whose origin is at the center of the inner aperture reference circle, the aperture inner periphery can be positioned along 0.4 to 0.6 of the entire circumference of the inner aperture reference circle. The insertion article can be configured for insertion in the apertured article.

A vehicle safety wheel is disclosed having a central disk and a rim concentrically disposed around the central disk. The central disk is compatible for mounting to a vintage hub with conventional wheel mounting hardware. The rim has an inboard flange and an outboard flange for mounting a tire to the rim, and an inner flange disposed inwardly of the outboard flange, concentric with the outboard flange for defining an annular-shaped space there-between. A fascia is adapted for mounting in the annular-shaped space, circumferentially extending between the outboard flange and the inner flange, with the fascia forming a visually continuous surface with a sidewall of the tire. The fascia may be embedded with a light source which is controlled in brightness and flashing by one of an accelerometer, a gyroscope, a brake sensor, and a turn sensor.

The connection also comprises a first plurality of layers of reinforcing fibers (24) extending in a generally radial direction R relative to an axis of rotation of the wheel (10), and along a front face of each spoke (18), across a front edge (26) and an inner annular surface (28) of the hub ring (22) and across a front face (30) of the hub plate (16); and a second plurality of layers of reinforcing fibers (32) extending in a generally radial direction R along a rear face (33) of each spoke (18), across a rear edge (34) of the hub ring (22) and across a rear face (36) of the hub plate (6). The connection further comprises a third plurality of layers of reinforcing fibers (36), the third plurality of layers (36) of reinforcing fibers overlaying the first and second (1) layers of reinforcing fibers (24, 32), the third plurality of layers of reinforcing fibers 36 extending in a direction between +30 degrees and +60 degrees to the radial direction R; and a fourth plurality of layers of reinforcing fibers (40), the fourth plurality of layers of reinforcing fibers (40) overlaying the first and second layers of reinforcing fibers (24, (32), the fourth plurality of layers of reinforcing fibers (40) extending in a direction (20) between 30 degrees and 60 degrees to the radial direction R.

A non-pneumatic wheel having a thermoplastic wheel hub includes a center hub for attachment to a wheel bearing of a vehicle. The center hub has a central shaft aperture extending axially therethough and a plurality of lug apertures spaced radially from and circumferentially about the central shaft aperture. The thermoplastic wheel hub also includes a plurality of ribs extending radially outwardly from the center hub. The thermoplastic wheel hub further includes a cylindrical tire mount connected to the ribs and extending axially in substantially a cylinder for mounting a non-pneumatic tire thereon.

A wheel (1) for a vehicle and a related method for manufacturing the wheel includes a rim (2) and a wheel center (3). The wheel center includes several spokes (4) extending from a hub (5), with a center opening (6), radially outwards to the rim (2). The hub (5) is made from a fiber-reinforced plastic material and is covered on the outboard side from a three-dimensionally shaped support cover (7) made from metallic material.

There is provided an automotive wheel with a cavity between the bolt holes in a hub mounting section, and more particularly, to an automotive wheel with a cavity between the bolt holes in a hub mounting section, wherein a cavity between the bolt holes in a hub mounting section structured to secure an automotive wheel to a wheel hub is uniformly formed to reduce the weight and noise of the automotive wheel, and wherein a damper rubber is inserted into the cavity to reduce the vibration and noise generated during driving an automobile.

A vehicle wheel element structure includes a center disc member, abutment members, and wheel-element-side fastening surfaces. Disc members extend radially in an outer diameter direction from the center disc member. The center disc member includes a center bore and fastening holes. The abutment members are provided on an inner side of the center disc member. Each abutment member protrudes from a position that is away from an opening of a corresponding one of the fastening holes by a predetermined distance. Each abutment member protrudes by a predetermined amount with respect to a reference plane when the abutment member is fastened to a hub unit. The abutment members abut first on a hub-side fastening surface. The wheel-element-side fastening surfaces are provided on the inner side of the center disc member. Each wheel-element-side fastening surface includes the corresponding one of the openings.

A molded irrigation pivot wheel rotationally molded from a linear low-density polyethylene resin that has a reversible offset wheel hub assembly mounted in a central transverse core of the wheel for attaching to a selected drive disc of an attached pivot line gearbox. The invention is particularly useful having a reversible offset wheel hub assembly that can be mounted to one or the other of two gearboxes where each gearbox having a different linear offset distance to its drive disc.
