Abstract
This invention relates to a driving apparatus being provided for an aircraft or other wheeled vehicle by providing at least two frictional rollers which are mounted spaced from each other and adapted to be positioned on opposite sides of the wheel assembly of the vehicle, whether this wheel assembly consists of a single wheel or two or more wheels. A moving or pressing means is provided for pressing the rollers into frictional contact with the wheels of such wheel assemblies by, for example, controlling the spacing between the rollers. Drive means are then provided for rotating at least one of the friction rollers causing the vehicle wheel or wheels in contact therewith to also be rotated to move the vehicle.
Claims63
An auxiliary apparatus for moving a vehicle having at least one wheel assembly on a surface, the apparatus comprising in combination:
- at least two friction rollers mounted spaced from each other;
- a connecting member for interconnecting said at least two friction rollers;
- positioning means adapted to permit said rollers to be positioned on opposite sides of a wheel assembly of said vehicle;
- pressing means for controlling the length of said connecting member between said rollers to thereby press said rollers against and into frictional contact with said wheel assembly;
- and
- drive means for rotating at least one of said rollers;
- whereby at least one wheel of said wheel assembly may be rotated by said roller to move said vehicle.
A method for moving a vehicle having at least one wheel assembly on a surface comprising the steps of:
- positioning an auxiliary apparatus having at least two friction rollers with the friction rollers on opposite horizontal sides of said wheel assembly, at least one of said rollers being positioned below the axis of at least one wheel of said assembly;
- controlling the spacing between said rollers to press all of said rollers into frictional contact with the wheels of said assembly, the contact points for at least two of said rollers being on opposite horizontal sides of said wheel assembly and the contact point for at least one of said rollers being below the axis of at least one of said wheels;
- and
- driving at least one of said rollers to rotate, thereby rotating the wheel in frictional contact therewith to move said vehicle.
An auxiliary apparatus for moving a vehicle having at least one wheel assembly on a surface comprising in combination:
- a U-shaped frame;
- means for mounting at least two friction rollers on said frame;
- positioning means adapted to position said frame around said wheel assembly with said rollers positioned on opposite horizontal sides of said wheel assembly;
- means for controlling the length of the connecting leg of said U-shaped frame, said means being operative when the length of said leg is shortened to press all said rollers into frictional contact with the wheels of said wheel assembly;
- and
- drive means for rotating at least one of said rollers;
- whereby at least one wheel of said wheel assembly may be rotated by said roller to move said vehicle.
An auxiliary apparatus for moving a vehicle having at least one wheel assembly on a surface, the auxiliary apparatus being locatable independent of the vehicle to be moved, the auxiliary apparatus comprising in combination:
- at least two friction rollers:
- means for positioning said friction rollers with at least one of said rollers on each horizontal side of said wheel assembly and with at least one of said rollers being positioned below the axis of at least one wheel of said assembly;
- means for moving at least one of said rollers in a direction to cause all of said rollers to be pressed into frictional contact with the wheel or wheels of said assembly, the contact points for at least two of said rollers being on opposite horizontal sides of said wheel assembly and the contact point for at least one of said rollers being below the axis of at least one of said wheels;
- and
- means for driving at least one of said rollers to rotate, thereby rotating the wheel in frictional contact therewith to move said vehicle.
A method for moving a vehicle having a least one wheel assembly on a surface comprising the steps of:
- providing an auxiliary apparatus locatable independent of the vehicle to be moved and having at least two friction rollers;
- positioning the auxiliary apparatus with the friction rollers on opposite horizontal sides of said wheel assembly, at least one of said rollers being positioned below the axis of at least one wheel of said assembly;
- moving at least one of said rollers in a direction to cause all of said rollers to be pressed into frictional contact with the wheels of said assembly, the contact points for at least two of said rollers being on opposite horizontal sides of said wheel assembly and the contact point for at least one of said rollers being below the axis of at least one of said wheels;
- and
- driving at least one of said rollers to rotate, thereby rotating the wheel in frictional contact therewith to move said vehicle.
An auxiliary apparatus for moving a vehicle having at least one wheel assembly on a surface, the auxiliary aparatus being locatable independent of the vehicle to be moved, the auxiliary apparatus comprising in combination:
- at least two friction rollers:
- means for positioning said friction rollers with at least one of said rollers on each horizontal side of said wheel assembly and with at least one of said rollers being positioned below the axis of at least one wheel of said assembly;
- means for controlling the spacing said rollers to press all of said rollers into frictional contact with the wheels of said assembly, the contact points for at least two of said rollers being on opposite horizontal sides of said wheel assembly and the contact point for at least one of said rollers being below the axis of at least one of said wheels;
- and
- means for driving at least one of said rollers to rotate, thereby rotating the wheel in frictional contact therewith to move said vehicle.
