Description

  The present invention relates to general automobiles such as three or more passenger cars, buses, trucks, and heavy machinery.

  More than 100 years have passed since the automobile was developed. Although automobile wheels have evolved from circular to cylindrical and wooden to rubber, the basic shape is circular and not much changed. A circular wheel has an advantage that it is excellent in ability to rotate in a direction perpendicular to the central axis and is stable because the axis is fixed. The direction of travel can be freely changed by steering the central axis to the left and right.

Embodiments of the present invention will be described below with reference to the drawings.
FIG. 1 shows a cross-sectional view of a spherical wheel in an automobile of the present invention. As shown in FIG. 1, most of the outer peripheral surface of the spherical wheel is covered with a rubber tire 11, and the inside is a cavity 12. The inside is filled with compressed air and maintains a spherical shape. Several portions of the rubber tire 11 are provided with air filling ports 13 so that air can be filled therein. The mechanism of the air filling port 13 is the same as that of a general automobile wheel. The air filling port 13 has a structure that is slightly deeper than the rubber tire 11 so as not to hit the road surface.

  FIG. 2 shows an external view of a spherical wheel. Although the air filling port can be filled with air only at one place, it is desirable that there are several places for filling the air while it is installed in the automobile. For example, when a regular tetrahedron inscribed in a spherical surface is imaged, four air filling ports are arranged at the positions of the four apexes.

  In FIG. 3, the external view of the holder | retainer which fixes a spherical wheel is shown. A cage main body 32 is arranged so as to cover the spherical wheel 31. The upper part of the cage main body 32 has a hexagonal plate shape with three legs growing from it. The cage main body 32 is not in direct contact with the spherical wheel 31, but is in contact with nine holding balls 33 attached to the cage main body 32. At least four holding balls 33 are necessary for fixing the spherical wheel 31, but a certain amount of the holding balls 33 located on the upper part of the spherical wheel 31 is required to support the weight of the vehicle body. This time it was six. All the holding balls 33 contain grease inside the cage body 32 so that the frictional force is reduced with respect to the spherical wheels 31 and the cage body 32. As a result, the position of the spherical wheel 31 is completely fixed, but the rotation can be freely performed in any direction. There is a refracting portion 34 on one leg of the cage body 32. Normally, it is in a closed position as shown in the figure, but when the spherical wheel 31 is replaced, it is bent outward. Although not shown in the figure, a vehicle body is on the upper part of the cage via a suspension and a shock absorber. The suspension and shock absorber are almost the same as those of a conventional automobile.

  In FIG. 4, the external view which looked at the holder | retainer from the side is shown.

  FIG. 5 shows a driving device for driving a spherical wheel. As described above, the cage 52 is arranged so as to cover the spherical wheel 51. A drive shaft 53 is arranged in a gap portion of the cage 52 while shifting the angle. A drive shaft belt 54 is attached to a contact portion between the spherical wheel 51 and the drive shaft 53 so that the spherical wheel 51 can be driven by a frictional force. The rotation from the drive shaft at the center of the vehicle body is transmitted to the drive shaft, and is transmitted by the universal joint 55 at an angle shifted immediately before the wheel portion. When the first drive shaft 53a and the second drive shaft are rotated in the same direction, that is, in the same phase, the automobile advances in the front-rear direction and in the vertical direction in the figure.

  A method of steering left and right will be described with reference to FIG. When the same driving force is transmitted from the drive shaft at the center of the vehicle body to the two drive shafts, the wheel advances straight in the direction of the figure. If the power from the drive shaft is transmitted using a differential with a difference in torque, the left and right power can be adjusted. As shown in the figure, when the first drive shaft 62 is transmitted with a stronger power than the second drive shaft 63, it can proceed straight from the right. Conversely, if the first drive shaft 62 is transmitted with weaker power than the second drive shaft 63, it can proceed straight from the left.

  FIG. 7 shows a method of driving a spherical wheel left and right. As shown in the figure, when the first drive shaft 72 is rotated in the opposite direction to the second drive shaft 73, that is, in the opposite phase, the spherical wheel 71 can be driven in the left-right direction.

  FIG. 8 is used to show a method of translating a vehicle from side to side. As shown in the figure, when the four spherical wheels are driven in the same direction on the left and right, the automobile moves in parallel to the left and right.

  FIG. 9 shows a method of rotating the automobile. As shown in the figure, when two front wheels and two rear wheels among the four spherical wheels are driven in the left and right direction, the automobile rotates.

  FIG. 10 shows a braking device for braking a spherical wheel. A braking device 103 is disposed in a gap portion of the cage 102. Although not shown in the drawing, a driving device is positioned on the braking device 103 as shown in FIG. The brake device 103 is interlocked with a brake pedal. When the brake pedal is depressed, the brake device 103 is pressed against the spherical wheel 101 and brakes by frictional force.
