Land transportation vehicles using pneumatic tires loose air over time, including tractor trailers, private vehicles, race cars and other vehicle classifications. Tire pressure is important, but only a small number of attendants are concerned. Our invention is an automatic device which supplies air to tractor trailer tires using an onboard air supply. This air, supplied to the rotary air chamber system can be adjusted to a desired tire air pressure by the individual driver to suitable levels of load weights, climates, travel speed and terrain. Rotating tires at high speeds build up friction raising tire pressure to dangerous levels. This will be corrected by built in relief valves. To maintain and verify tire pressures each tire is protected by check valves and visible pressure gauges. The rotary air chamber automates, corrects continuously the neglect of proper tire maintenance, adds road safety for users and public alike.

A method of verifying the integrity of a valve in service in a tire pressure management system is disclosed.

The invention provides an anti-leakage tire and preparation method thereof. A gelatin elastic material, which is a blend of vulcanized rubber, thermoplastic elastomer and resin, is applied on the inner surface of the anti-leakage tire. The preparation method comprises the following steps: (1) adding raw materials into a reaction kettle, stirring while heating, and dispersing to obtain a uniform and flowable blend; (2) adjusting the temperature of the blend; and (3) transporting to the sprinkler of a metering pump by a transport pump, and spraying on the bottom of the inner wall of the tire to form a uniform elastomer coating with a thickness of 3 to 5 mm and with self-sealing performance. The test shows that the tire pressure is normal and no leakage is present when the tire having 10 iron nails pinned therein experiences 3,000 miles high-speed running in high-temperature and low-temperature environment. The method can effectively solve the problems of micro-leakage and pinned leakage, thus lowering the tire maintenance cost, improving the running safety and achieving remarkable social and economic benefits.

A semitrailer underbody screen and wheel-set fairing kit comprises several panels and fairings for retrofitting on conventional semitrailers. A sectioned panel like fish scales covers the dozens of transverse I-beam cross-members positioned underneath conventional enclosed trailer floors, and carries on down the length of the underbody. A v-hull air deflector is set just beneath these panel covers, ahead of the semitrailer's undercarriage, suspension and tandem rear axle wheels. Such v-hull air deflector splits and aerodynamically “flows” the air being pushed ahead outwards to the sides and around the wheels. The tandem rear axle wheels themselves are completely boxed inside full fenders that cowl over the front, sides, top, and rear. Removable access panels are provided on the outsides of the full fender units for wheel and tire maintenance. The result is significantly less wind drag and noise at highway cruising speeds. Less drag means better fuel economy for the tractor operator.
