PCT No. PCT/SE87/00520 Sec. 371 Date Jun. 9, 1989 Sec. 102(e) Date Jun. 9, 1989 PCT Filed Nov. 5, 1987 PCT Pub. No. WO88/03492 PCT Pub. Date May 19, 1988.A wheel assembly for moving an object, such as load carrying vehicles, and similar types of machines. The assembly enables unique motion possibilities, such as changing the direction of the object's motion perpendicularly to a preceding direction of motion. The assembly includes a wheel, which can be either driven or freely rotatable, for propelling the vehicle. The rolling point of the wheel rests upon a support surface, which is positioned at a radial distance from a drive shaft. To change the direction of motion, the wheel is rotated around the drive shaft, along a circle having the aforementioned radius. |
