Claims
- 1. A multi-wheel vehicle comprising:
a pair of first running wheels serving as driving wheels; a pair of second running wheels disposed before or behind said pair of first running wheels, wherein said pair of second running wheels are laterally turned into the traveling direction of said vehicle; a pair of third running wheels disposed before or behind said pair of first running wheels; a prime mover: a speed change operation means; a steering operation means; a transmission drivingly connected with said prime mover; and a pair of running-driving axles onto which said respective first running wheels are attached, wherein said transmission applies composite force of first equal rotational forces in the same directions and second equal rotational forces in opposite directions onto said pair of first running wheels, wherein said speed change operation means is manipulated so as to regulate the direction and magnitude of said first rotational forces, and wherein said steering operation means is manipulated so as to regulate the direction and magnitude of said second rotational forces.
- 2. The multi-wheel vehicle as set forth in claim 1, wherein said second running wheels are steerable wheels interlocking with said steering operation means.
- 3. The multi-wheel vehicle as set forth in claim 1, wherein said second running wheels are castors.
- 4. The multi-wheel vehicle as set forth in claim 1, wherein said pair of second running wheels are disposed before said pair of first running wheels, and said pair of third running wheels are disposed behind said pair of first running wheels.
- 5. The multi-wheel vehicle as set forth in claim 1, wherein said pair of second running wheels are disposed behind said pair of first running wheels, and said pair of third running wheels are disposed before said pair of first running wheels.
- 6. The multi-wheel vehicle as set forth in claim 1, further comprising:
a pair of second axles disposed in parallel to said pair of running-driving axles, wherein said third running wheels are attached onto said respective second axles.
- 7. The multi-wheel vehicle as set forth in claim 6, wherein driving force of said running-driving axles is transmitted to said pair of second axles.
- 8. The multi-wheel vehicle as set forth in claim 7, wherein a pair of power transmission mechanisms are interposed between said respective running-driving axles and said respective second axles so as to rotate said pair of second axles in the same rotational direction of said first running-driving axles.
- 9. A multi-wheel vehicle comprising:
a pair of first running wheels serving as driving wheels; a pair of castors as second running wheels disposed before or behind said pair of first running wheels; a pair of third running wheels disposed before or behind said pair of first running wheels; a prime mover: a speed change operation means; a steering operation means; a transmission drivingly connected with said prime mover; and a pair of running-driving axles onto which said respective first running wheels are attached, wherein said transmission applies composite force of first equal rotational forces in the same directions and second equal rotational forces in opposite directions onto said pair of first running wheels, wherein said speed change operation means is manipulated so as to regulate the direction and magnitude of said first rotational forces, and wherein said steering operation means is manipulated so as to regulate the direction and magnitude of said second rotational forces.
- 10. The multi-wheel vehicle as set forth in claim 9, wherein said pair of castors are disposed before said pair of first running wheels, and said pair of third running wheels are disposed behind said pair of first running wheels.
- 11. The multi-wheel vehicle as set forth in claim 9, wherein said pair of castprs are disposed behind said pair of first running wheels, and said pair of third running wheels are disposed before said pair of first running wheels.
- 12. The multi-wheel vehicle as set forth in claim 9, further comprising:
a pair of second axles disposed in parallel to said pair of running-driving axles.
- 13. The multi-wheel vehicle as set forth in claim 12, wherein driving force of said running-driving axles is transmitted to said pair of second axles.
- 14. The multi-wheel vehicle as set forth in claim 13, wherein a pair of power transmission mechanisms are interposed between said respective running-driving axles and said respective second axles so as to rotate said pair of second axles in the same rotational direction of said first running-driving axles.
