DRIVING DEVICE FOR WHEEL OF AIRPLANE
First Claim
1. A driving device for wheel of airplane driving the wheel in such a direction same as the revolution of the wheel after landing by utilizing the relative atmospheric air flow the airplane receives before landing, comprising;
- a ringed flat plate constituting the attaching means to attach on the side surface of the tire,fins arranged at the predetermined pitch in the peripheral direction on the ringed plate, the fins being obviously arranged on the ringed plate so that the torque by the fin at the lower side of the tire in the direction same as the revolution of the wheel after landing is larger than the torque by the fin at the upper side of the tire reverse to the revolution of the wheel after landing,wherein, the ringed plate is attached to the side surface of the tire.

Abstract
The device of this invention comprises a revolution drive disc 20 which has a rubber ringed plate 21 and plural fins 22. The fins 22 are obliquely attached on the outside surface of the ringed plate 21 so that torque by the fin 22 at the lower side of the tire in the direction same as the revolution of the wheel after landing is larger than the torque by the fin 22 at the upper side of the tire in the direction reverse to the revolution of the wheel after landing. The revolution drive disc is adhered on the side surface of the tire 17 through the rubber group adhesive. The wheel of the airplane, drawn out from the body, rotates in the direction same as the revolution of the wheel after landing due to the atmospheric air flow by the flight before landing. Thus the change of the number of the revolution at the moment of touch down on landing is reduced or gone, resulting in the reduction of the wear and damage of the tire and the reduction or prevention of the adhere of the remnant or residue of the tire on the runway.

9. A driving device for wheel of airplane driving the wheel in such a direction same as the revolution of the wheel after landing by utilizing the relative atmospheric air flow the airplane receives before landing comprising;
-
a pair of ringed flat plates which are arranged parallel in the axial direction at the predetermined space and constitute the selective attaching means to attach to the side surface of the tire, fins arranged between the pair of ringed plates peripherally in the predetermined pitch, the fins being obliquely disposed so that the rotational and normal torque normal to the direction of the revolution after landing by the lower portion of the tire is lager than the rotational and reverse torque reverse to the direction of the revolution after landing by the bottom portion of the tire, the revolution drive disc is comprised of the pair of ringed plates and the fins, and one of the pair of the ringed plates is attached to the side surface of the tire by the adhesive. - View Dependent Claims (10, 11, 12, 13, 14)
