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 pulley assembly having a body, a shaft mount and a plurality of bolts is disclosed. The body is aligned to the shaft mount by providing a tight tolerance between a shoulder portion of the bolt and a neck portion of a counter sunk hole formed in the body. Additionally, an outer surface of the body may have a pattern of friction lines or patches formed by fusing particulate matter to the outer surface with heat generated by a laser beam.

Bicycle rims that allow tires to be more easily mounted in a tubeless configuration are disclosed. More specifically, a bicycle rim may control the two beads of the tire with separate bead channels for each bead and a center bridge extending between the two bead channels.

Adapter for a rolling assembly having an axis of rotation comprising a tire having two beads, a rim with rim well (13) between two rim seats (12) each with an axially outer end, and width W between axially outer ends of these rim seats. The adapter, coupled between each bead and each rim seat, has two axially outer ends (2) each comprising seat (3) and bearing face (4) in a plane perpendicular to the axis of rotation. Body (5) connects outer axial ends (2) and comprises a main reinforcement, face (16) in contact with each seat (12) and with well (13) and positioned radially on the inside. The adapter has a total axial width L between each seat (3), and 60%W/L20%. Body (5) comprises immobilizing element (8) to wedge the adapter in the rim well (13).

A vehicle wheel rim for use on a motor vehicle, having a wheel rim well (1, 29), having an inner wheel rim flange (7, 30) and having an outer wheel rim flange, wherein the wheel rim well (1, 29) is delimited at its axial end regions by in each case one of the wheel rim flanges (7, 30), wherein the wheel rim flanges (7, 30) are formed by a radially encircling wall, said walls extending in each case at a predefinable angle (5, 27) with respect to the wheel rim well (1, 29).

An agricultural tool includes a wheel body and a flexible tire with a hollow chamber and an inner surface around this hollow chamber; a circular opening on the chamber; a pair of beads bordering this opening; and a spacer at least partially tubular with two axially opposite end faces. Over one portion corresponding to one of the beads, the inner surface extends frustoconically by widening radially outward of the flexible tire, and one of the end faces of the spacer has an axially protruding surface. The spacer is placed across the opening of the tire such that the protruding surface engages the inner surface in an area of the portion corresponding to the bead.

A system for reducing slippage between a tire and wheel rim includes providing anti-slip tape on the wheel rim at a wheel-tire interface of the wheel rim. When the tire is mounted on the wheel rim, the anti-slip tape is disposed between the tire and the wheel rim, providing a high friction abrasive surface in direct contact with the tire. The tape may be applied to the bead flanges of the wheel rim, which extend radially outward from the body portion of the wheel rim. The bead seats, which are adjacent the bead flanges, providing sealing between the tire and the wheel rim. The tape applied to the wheel rim extends around the circumference of the wheel rim, and may project outwardly from the surface of the wheel-tire interface, or may be disposed in a recess to be flush with the surface.
