PATENT OF THE WEEK – TIRE PRESSURE REGULATION SYSTEM

The TIRE PRESSURE REGULATION SYSTEM was invented on Donald G. Martus (Mt. Clemens, MI) on 18th February 1986, bearing the patent number US4570691A.

This invention relates to a wheel-tire assembly for use on a ground vehicle (e.g., a military truck) operating on soft or hard terrain over a range of vehicle speeds.

A vehicle wheel-tire assembly wherein the tire has a low inflation pressure (large tire footprint) in a low vehicle speed range, and a large inflation pressure (small tire footprint) in a high vehicle speed range. The tire is partitioned into a series of circumferential compartments, with each compartment being provided with a valve mechanism for introducing air into the compartment and/or withdrawing air from the compartment as needed to maintain desired inflation pressures in the different vehicle speed ranges. The system is contained entirely in the wheel-tire assembly; no external air compressors or control valves are utilized.
