Abstract: A wheel assembly apparatus is disclosed. In at least one embodiment, a wheel hub is coaxially positionable within a wheel. A first bearing and a laterally opposed second bearing are each positionable coaxially within the wheel hub, with an inwardly facing medial surface of the first bearing being laterally spaced apart from an opposing inwardly facing medial surface of the second bearing so as to form a bearing gap therebetween. A first outer spacer is positionable in contact with an outwardly facing lateral surface of the first bearing, and a second outer spacer is positionable in contact with an outwardly facing lateral surface of the second bearing. Accordingly, an axle is capable of extending coaxially through each of the first outer spacer, first bearing, second bearing, second outer spacer, wheel hub and wheel, thereby enabling the wheel to rotate about the axle.

Abstract: A chassis foam sprayer comprises a bottom plate, a solvent pot and a flushing pipe arranged above the bottom plate, rollers arranged below the bottom plate, and an upper cover covering above the bottom plate, wherein one end of the flushing pipe is provided with a water inlet connector which can be externally connected with a high-pressure water gun, the other end of the flushing pipe is provided with at least one nozzle, and a connecting pipe is arranged between the solvent pot and the flushing pipe; the high-pressure water gun is fixedly connected with the water inlet connector by arranging the rollers on the bottom plate, and then the foam sprayer is pushed in at the position of the chassis of the automobile, so that the position can be conveniently moved, and all positions of the chassis can be conveniently cleaned; moreover, the solvent pot is equipped with car wash liquid, so that the chassis can be subjected to foam spraying first, and then washed with clean water for thorough cleaning.

Abstract: A method for manufacturing a wheel integrated to a support shaft, including: making by overmolding, in a first material, of a wheelrim on the support shaft, the wheelrim having an upper face having a ribbed annular portion in which cells are formed, delimited by reinforcing ribs and having respective bottoms, making by overmolding, in a second material, of a crown on the upper face of the wheelrim, by implementing an injection in at least one injection point positioned opposite the ribbed annular portion, prior to the step of making the crown by overmolding, formation of a material deposit in at least one target cell, selected amongst the cells, so as to form a raised area with respect to bottom thereof, the injection of the second material at the injection point being performed opposite the raised area.

Abstract: A wheel assembly comprising a wheel disk and a tread member disposed around the wheel disk. The wheel disk can have a substantially conical shape when in an unloaded state, but be flexible such that it can deform under load to optimize and/or maximize contact area between the tread member and a driving surface.

Abstract: A wheel assembly includes a wheel and a hub assembly. The hub assembly includes a retainer housing, retaining member, biasing element, and restraining element. The retainer housing includes a wheel mounting sleeve and pin sleeve. The wheel mounting sleeve includes an axle bore configured to receive an axle and configured to be inserted within a sleeve bore of the wheel. The pin sleeve includes a first end fluidly communicating with the sleeve bore, a second end, and a conduit therebetween. The retaining member, disposed within the conduit, is configured to operatively engage an axle groove and includes a lip wider than a first end shoulder to prevent the retaining member from exiting the first end. The biasing element, disposed within the conduit, is configured to bias the retaining member towards the axle bore. The restraining element is configured to prevent the retaining member from exiting the second end.

Abstract: A wheel when viewed from the outside having the general appearance of a wheel with a tread pattern. The wheel comprising a hub having a central bore dimensioned and configured to receive an axle, a web extending radially from the hub, and an annular rim encircling the web, the rim including a plurality of deep recesses extending in a transverse direction from an inner surface to an outer surface of the rim, each deep recess having a depth substantially equal to a width of the rim. The wheel further includes a plurality of shallow recesses each having a depth less than the deep recesses.

Abstract: Freewheel flow track systems are adapted for transporting pallets and/or cartons in heavy-duty pallet and carton flow applications. A flow track system may include multiple track sub-assemblies, each track sub-assembly including multiple wheel assemblies. Each wheel assembly comprises a wheel rotatably mounted on an axle. A lubricant coating may be fixed to and bonded with the axle. The wheel may be constructed from a polycarbonate-based resin that is impregnated with a lubricant for providing lifetime lubrication to the wheels. The wheel includes a hub, a rim concentric with the hub, a web connecting the hub to the rim, and ribs connecting the hub to the rim through the web.

Abstract: A wheel for a child's toy formed from a first and second section. The first section is made from a material having a Shore A durometer of 100 or less. The second section is disposed within the first section. The second section is made from a rigid material and provides structural support for the wheel.
