| Abstract: |
Apparatus and method for reducing the air pressure ahead of the contact patch (20) of a rotating wheel (12) by directing an air jet (80) substantially at right angles or forwardly of right angle to the plane of the wheel to improve traction and heating characteristics. In an embodiment the air is heated so as to further improve the traction and other characteristics.

I CLAIM AS OUR INVENTION: 1. In a device having a rotating wheel adapted to contact a surface such that the wheel at the contact patch and the surface at the contact patch have the same velocity, means for supplying a gas jet substantially perpendicular to the plane of the wheel at a location which is slightly ahead of the contact patch.

+ IMPROVING WHEEL TRACTION
CROSS-REFERENCES TO RELATED APPLICATIONS
+ BACKGROUND OF THE INVENTION
+ Field of the Invention This invention relates in general to devices and apparatus for improving the air flow around the wheel.
Description of Related Art As wheels of vehicles rotate, the air dynamics associated with rotating wheels becomes increasingly important. When the vehicle is moving at relatively high speeds, the oncoming air can create a number of problems as it strikes the wheel. For example, the air striking a lower portion of the wheel tends to be compressed immediately in front of the contact patch between the wheel and the roadway and to lift the wheel off the roadway. This leads to heating of the ambient air, heating of the wheel, reduced traction on the road, and moisture condensation due to the air being compressed ahead of the contact patch. At extreme speeds, the heated compressed air can float the wheel out of contact with the roadway.
+ SUMMARY OF THE INVENTION
It is an object of the present invention to improve the air flow immediately before the contact patch of a rotating wheel so as to control wheel temperature, improve friction, enable faster acceleration, deceleration and higher speeds of the vehicle, and provide for improved control of the vehicle.
+ Brief Description of the Drawings
FIG. 1 is a side plan view illustrating the invention; FIG. 2 is a top plan view illustrating the invention; FIG. 3 is a top plan view illustrating the invention; FIG. 4 is a top plan view of the invention illustrating the air jet nozzle pointed in a direction somewhat ahead of perpendicular to the direction of movement of the wheel; FIG. 5 is a top plan view illustrating air ducts supplying air to air nozzles to the region ahead of the contact patches; FIG. 6 is a top partially schematic view of a modification of the invention; and FIGS. 7A, 713 and 7C are views of a spoiler incorporating the invention. ###
+ DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
As shown in FIGS. 1-6 as the vehicle moves, ambient air is forced between the tire and the road surface (the contact patch). In the present invention, high velocity air is used to divert the oncoming air as seen in FIGS. 1-6.
