    摘要: A movable tire inflation apparatus includes an inflation device and a fixing structure. The inflation device includes a casing defining an accommodation room. The accommodation room is equipped with an inflation component, and an electrical control module which is connected electronically to the inflation component. At least one magnetic positioning member is disposed at one side of the casing. The fixing structure is disposed at an outer side of the inflation device in such a manner to fix the inflation device on an outer side of a wheel and the magnetic positioning member is magnetically positioned at one side of the wheel. In this way, the movable tire inflation apparatus is fixed on the outer side of the wheel and connected to the wheel by the inflation device, to inflate a tire as the wheel is moving, providing advantages in easy carriage, repair convenience and safety improvement.

    摘要: A tire assembly includes a reservoir, a tire, and a pressure module. The pressure module includes a first valve, a second valve, and a control unit. The first valve selectively directs air from the reservoir to the interior cavity. The second valve directs air from the interior cavity of the tire to the atmosphere. The control unit is configured to selectively send a first control signal to the first valve such that the first valve cycles from a first position, at which air is prevented from flowing from the reservoir to the interior cavity, to a second position, at which air is allowed to flow from the reservoir to the interior cavity of the tire. The control unit is configured to selectively send another first control signal to the first valve such that the first valve cycles from the second position to the first position.

    摘要: A wheel assembly has a rim with an outer radial surface. A tire coupled to the rim defines a first interior region between the outer radial surface and the tire. A bladder coupled to the rim defines a second interior region between the outer radial surface and the bladder. A third interior region is defined between the bladder and the tire. The wheel assembly includes a valve fluidly coupled to the second interior region and the third interior region. The valve is movable between a first position and a second position. The second interior region and the third interior region are fluidly isolated from one another when the valve is in the first position. The second interior region and the third interior region may be fluidly coupled to one another when the valve is in the second position.

    摘要: A pneumatic tire assembly includes a tire having a pneumatic cavity and a filter disposed between the pneumatic cavity and atmosphere. The filter is constructed of a hydrophobic material for avoiding all liquid adhesion. First and second sidewalls extend respectively from first and second tire bead regions to a tire tread region. The first sidewall has at least one bending region operatively bending when radially within a rolling tire footprint. A sidewall groove is defined by groove walls positioned within the bending region of the first tire sidewall. The sidewall groove deforms segment by segment between a non-deformed state and a deformed, constricted state in response to bending of the bending region of the first sidewall while radially within the rolling tire footprint.
