Abstract

A controlling method in a transporting machine such as airplane, automobile, etc. adapted to be obtainable a different friction resistance for a same running surface with an identical tire bringing its surface portion with a different friction coefficient in contact with the ground by means of changing an angle of a tire to a running ground surface.

Claims

1. In a vehicle, a wheel having an axis of rotation which normally extends horizontally during normal travel of the vehicle, said wheel having an outer road-engaging peripheral surface of a predetermined width in a direction parallel to the wheel axis which normally engages the road surface during normal travel of the vehicle when said wheel axis is substantially horizontal, said wheel having a region of maximum width greater than the width of said road-engaging surface situated adjacent but spaced from said road-engaging surface, and said wheel having peripheral side surfaces which are convexly curved and merge into said road-engaging surface and said region of maximum width, at least one of said side surfaces carrying a means for increasing the friction between said wheel and a road when said one side surface engages the road, said means for increasing the frictional engagement between said wheel and road being limited only to said one side surface, and tilting means operatively connected with said wheel for tilting the latter to incline said axis thereof in a direction which places said one side surface in engagement with the road to increase the frictional engagement between the wheel and road.

2. The combination of claim 1 and wherein the vehicle is a vehicle such as an automobile which is intended to travel only on a supporting road, said wheel having an outer side directed outwardly away from the vehicle and an opposed inner side, and said one surface being located at the inner side of the wheel while said tilting means coacts witH said wheel for tilting the latter between a normal position in a substantially vertical plane and an inclined position where said one surface is displaced at its lower end which engages the road outwardly away from an opposed wheel of the vehicle to increase the distance between said wheels and lower the vehicle when said wheel is tilted to place said one surface in engagement with the road.

3. The combination of claim 2 and wherein said opposed wheel is identical with the first-mentioned wheel and is a mirror image of the latter, said tilting means being operatively connected with both of said wheels for simultaneously tilting the latter between positions where both wheels are respectively in substantially parallel vertical planes to positions where the lower portions of said inside surfaces engage the road and are situated from each other by a distance greater than when said wheels are in said vertical planes.

4. The combination of claim 1 and wherein the vehicle is an airplane which engages a road during take-off and landing and during taxiing. said wheel forming one of a pair of wheels carried by an undercarriage column of the airplane, and said pair of wheels normally having a common axis of rotation, said side surface of each of said wheels which carries said friction-increasing means being situated at the outer side of each wheel, and said tilting means being carried by said column and being operatively connected with said wheels for tilting the latter simultaneously in opposite directions which displace said outer side surfaces toward each other at their lower regions in order to engage the road.

5. The combination of claim 4 and wherein said wheels are located close enough to each other to directly engage each other after said tilting means tilts said wheels through a given angle so that said wheels reinforce each other when said outer side surfaces thereof engage the road.
