FILTER FOR A PNEUMATIC TIRE

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.

1. A pneumatic tire assembly comprising:
a tire having a pneumatic cavity; a filter disposed between the pneumatic cavity and atmosphere, the filter being constructed of a hydrophobic material for avoiding all liquid adhesion; first and second sidewalls extending respectively from first and second tire bead regions to a tire tread region, the first sidewall having at least one bending region operatively bending when radially within a rolling tire footprint; and a sidewall groove defined by groove walls positioned within the bending region of the first tire sidewall, the sidewall groove deforming 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, an air passageway is defined by the sidewall groove and deforms segment by segment between an expanded condition and an at least partially collapsed condition in response to respective segment by segment deformation of the sidewall groove when radially within the rolling tire footprint.
