Description

DETAILED DESCRIPTION OF THE INVENTION In FIG. 1, the sprocket (
2) and chain (3) to transfer the rotational force to the differential (4).
), and the sprocket (6) of the output shaft (5) and chain (7) rotate the sprocket (8). The rear wheels (9) and (9a) are fitted with sprockets (8) and (8a), respectively.
) and is driven.

When the vehicle body tilts when turning, the rear fork (10), (1
0a) alternately move vertically around the differential output shafts (5) and (5a), so both rear wheels (9) and (9a) also tilt relative to the ground, as shown in Figure 2. This causes the entire vehicle to tilt at the same time.

As an effect of the present invention, even a three-wheeled vehicle can be turned with the same steering feeling as a two-wheeled vehicle. Figure 4 shows how the center of gravity moves inward and lower; Figure 5 shows how the center of gravity moves in the same way in the case of the present invention; This means that a favorable camber thrust will occur as well.

When one wheel momentarily rides on gear (11),
In FIG. 6, the rear wheels of a conventional tricycle in which both wheels are connected by a single shaft are tilted together, and the center of gravity moves. FIG. 7 shows how only one wheel springs up in the case of the present invention. As time passes in this state, the center of gravity will rise, but momentarily, the amount of movement of the center of gravity is determined by the damper (11).
Due to the function of This figure also shows that both wheels can stand vertically even if they are located on an inclined surface. On the other hand, in FIG. 6, since it is perpendicular to the slope, the center of gravity moves toward the valley side, making it easier to fall.
