Title:
AIR MAINTENANCE PUMPING SYSTEM AND TIRE
Document Type and Number:
Japanese Patent JP2016003012
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an air maintenance feature that maintains air pressure within a tire to compensate for any reduction in tire pressure over time without the need for driver intervention.SOLUTION: A tire assembly includes a tire having a pneumatic cavity, 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 radially within a rolling tire footprint, and a chafer component having an air passageway defined by an air tube deforming in response to the sidewall deforming segment by segment radially within the rolling tire footprint. The tire assembly pumps a constant volume of air for every revolution of the tire thus providing a linear pumping rate regardless of dead volumes in the tire.
