<p>PURPOSE:To make it possible to smoothly run a vehicle on a bad road or even on the water, by making both tread distances between front wheels and as well rear wheels substantially equal and as well using balloon type wheels as the front and rear wheels. CONSTITUTION:Wheels 3, 3, 4, 4 are of balloon type and have large ground contact areas while the road surface gripping of the wheels is enhanced. The tread distances between the front wheels and as well the rear wheels are made substantially equal to each other, and further, the gravitational center of a vehicle body is in the vicinity of the crossing point of the line connecting between the center of the right front wheel 3 and the center of the left rear wheel 4, and the line connecting between the center of the left front wheel 3 and the center of the right rear wheel 4. With this arrangement, the distribution of load exerted to the wheels 3, 3, 4, 4 is made uniform, and the contact surface pressures between the tires and the road surface are made equal together so that drive force may be sufficiently transmitted to the road surface, resulting in that the occurrence of slip may be eliminated.</p> |
