A non-inflatable tire for an agricultural implement, including a sole, a tread, and a pair of sidewalls connecting the sole to the tread is provided. A first sidewall extends from the sole to the tread, while the second includes an internal portion which extends from the sole to the tread and an external portion projecting from the tread. The first sidewall and the tread are designed so as to jointly hold the external portion of the second sidewall in line with the internal portion.

This invention discloses a novel product of a Wheel Hub Assembly for damping and noise reduction. It absorbs vibration and noise of brake rotor and brake drum in the braking process by changing flange face structure as well as adding damping coating. During the production, the flange face of the Wheel Hub Assembly is equipped with one or several technical groove(s) while a damping coating is designed to reduce vibration and noise. The damping coating is made of rubber materials, composite materials, damping coating materials or high polymer materials. In this invention, the damping coating is added between wheel hub and brake disk or brake drum. This can not only absorb a part of noise, but also reduce braking vibration to decrease the noise.

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.

A bicycle wheel has a wheel frame. The wheel frame is a hollow and annular frame and is composited by multiple equally sized wheel bars. Each one of the wheel bars has two halves connected to each other to form the wheel bar, and each one of the two halves being made by laminating, heating and forming a thermoplastic prepreg. The equally sized wheel bars are connected to each other to form the bicycle wheel.

Provided is a non-pneumatic tire in which a plurality of curved sections (21d) to (21 f) and (22d) to (22f) curved inward in a tire circumferential direction are formed at elastic connecting plates (21) and (22) in an extension direction in which the elastic connecting plates (21) and (22) extend when seen in a tire side view such that curved directions are alternately opposite to each other in the extension direction, outer curved sections (21e) and (22e), inner curved sections (21d) and (22d), and extension sections (21i) (22i) extending throughout both of the curved sections and in which inflection sections (21g) and (22g) formed between both of the curved sections are disposed, are formed at the elastic connecting plates (21) and (22), and the extension sections (21i) and (22i) extend along reference lines having radii of curvature larger than that of the outer curved sections (21e) and (22e) and the inner curved sections (21d) and (22d) when seen in the tire side view and extend from first end portions (21a) and (22a) of the elastic connecting plates (21) and (22) connected to an outer tubular body (13) to arrive at a central portion in at least the extension direction.

A wheel for a non-motorized vehicle (e.g., a shopping cart) can include a housing assembly and a tread assembly. The housing assembly can be configured to sealingly house electronics or other components. The tread assembly can removably mate with the housing assembly such that the electronics or other components remain closed and/or sealed within the housing assembly when the tread assembly is mated or unmated with the housing assembly.

A vehicle wheel includes: a wheel having a rim; a sub-air chamber member serving as a Helmholtz resonator; and a support member integrated with the sub-air chamber member and joined to the rim. The sub-air chamber member is made of a synthetic resin. The support member is made of a metal.

A bicycle wheel comprises a rim and a valve assembly. The rim includes a radially inner wall having an inner opening and a radially outer wall having an outer opening. A first portion of the rim includes a first securing feature (e.g., inner threads). The valve assembly is positioned in the inner opening and outer opening and includes a second securing feature (e.g., outer threads) engaging the first securing feature. The rim can include a plate that defines the first engaging feature. The valve assembly preferably includes a valve stem and a resilient bumper coupled to the valve stem and aligned with a second portion of the rim. The valve assembly can further include a seal member compressed between the valve stem and the rim. Preferably, the seal member is positioned in an annular groove in an underside of an enlarged head of the valve stem.

A protector for a wheel is formed from a plurality of segments. Each segment is formed from a synthetic material and has an arcuate distal edge of a first radius, the distal edge forming a lip to engage a distal edge of the wheel. Each segment has at least two spoke adjacent edges and an arcuate proximal edge with a second radius less than the first radius. In some embodiments, the proximal edge defines a hook to engage an inner recess of the wheel. Each spoke adjacent edge is configured to reside near a spoke of the wheel during use. In some embodiments, a protrusion extended from the lip serves as a pinch point when a tire deforms during an impact event.

A cast wheel having an alloy substrate includes a primary surface and a secondary surface. A first polymeric coating is applied to the primary surface and to the secondary surface sealing the cast alloy wheel within the first polymeric coating. An intermediate polymeric coating is applied over the first polymeric coating. The intermediate polymeric coating is coated with metal using physical vapor deposition with the metal being aesthetically distinguishable from the first polymeric coating. A third polymeric coating is applied over the metal. The third polymeric coating, the intermediate coating and the metal from the primary surface of the cast alloy wheel are removed aesthetically distinguishing the primary surface from the secondary surface. A fourth polymeric coating is applied over the primary surface and the secondary surface.
