Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the running of a four-wheeled vehicle. Conventionally, when a four-wheeled vehicle runs and turns its wheels, the vehicle body tilts outward in the direction opposite to the turning direction, and at the same time the centrifugal force This causes a force to be thrown outwards, and in addition, a force to throw the cargo and the driver outwards, resulting in a loss of body balance and a failure to turn the steering wheel, even if the vehicle is not necessarily overspeeding. Drivers may jump into the opposite lane and collide with oncoming cars or utility poles, or they may fail to turn the steering wheel more than necessary due to their haste, causing them to roll over. Many drivers know that tilting the car by a certain degree makes steering easier and easier to drive.

The present invention eliminates the above-mentioned drawbacks of four-wheeled vehicles, and improves running safety (hard to rollover, hard to slip, the vehicle body leans inward in the turning direction,
Also, since there is no difference between the inner wheels, the rear wheels follow the track of the front wheels, and the turning angle of the wheels can be less than half of the turning angle of the conventional front wheels. Conventionally, the maximum turning angle was 45 degrees, so it only needed to be less than half that, 22.5 degrees, and Figure 1 shows the maximum turning angle.
Shows 22.5 degrees.

If the configuration of the present invention is explained based on the drawings, the first
In the figure, reference numeral 1 denotes a handle; for example, when it is rotated to the right, it passes through the worm wheel 2, the steering arm 4 that communicates with the steering gear 3, the steering rod 5, and the steering arm 6.
The wheel axle 7 is pivoted around the steering joint 8 by a guide fitting 9, and when the vehicle turns in the direction of the arrow in the detailed view of FIG. Since the wheel axle 9 is tilted, the wheel axle 7 rises diagonally upwards, and the wheels go up and the car body goes down.Also, the other wheel axle 10 goes down and the car body goes up, and the rear wheels go up and down in the same way. , the right axle arm 12 is connected to the wheel axle 7 and the pointing arm 6
The wheel axle 7 rotates around the steering joint 8 perpendicular to the plane, and the right axle arm 12 is fixed in the same plane. In a four-wheeled vehicle such as a passenger car, which is connected to the transmission rod 11 by a pin at its end, and which has a relatively light body weight, the centrifugal force causes straight-line (tangential) ) has a small kinetic energy, so it is clear from Figure 3 that the angle can be smaller than the 5° angle shown in Figure 3.
For this reason, the guide bracket diagram for a car body with a 3° inclination is shown in Figure 4.
4, the guide fitting 9 of FIG. 2 and the steering joint 8 of FIG. 1 are joined, and the inclination angle of the guide fitting 9 is also reduced.

Since the present invention is constructed as described above, when the handle 1 is rotated, for example, to the right, the front and rear wheels on the right side move upward while turning, and the wheels on the left side move downward. As a result, the vehicle body leans to the right. This downward and upward force is balanced on the left and right balances, and when returning to a straight line while driving, the centrifugal force causes the vehicle body to move in the direction (the vehicle body always tilts inward when turning). This makes it easier to operate the steering wheel, and when the car body is tilted, the centrifugal force acts on the body instead of on the body, making the body even more stable. Moreover, the present invention can be applied not only to rear-wheel drive vehicles but also to front-wheel drive vehicles, and in terms of ride comfort, unlike conventional vehicles, the uncomfortable bumping of the body against the left and right inner walls while driving is avoided. Also, the outside wheels do not make any squeaking noises or strain the drive system when turning, and the outer wheels are lowered, extending toward the ground, and are therefore centered around the center of gravity of the car. , the car body rotates, the inner wheels are pressed against the ground at the same time, and the rear wheels do not move towards the inner wheels, but move towards the outer wheels.
Immediately, it passes through the tracks of the front wheels, eliminating the force of overturning.
Furthermore, as mentioned above, the present invention protects drivers and pedestrians from accidents.Also, the present invention maintains the vehicle body horizontally when traveling on a straight road, and prevents the front and rear wheels from turning when traveling straight. For example, conventional cars drive
After traveling 500m, the direction of the vehicle changed to the right by 1°.
If you correct the steering wheel to the left by feeling it with your eyes, the front and rear wheel turning vehicle will travel 250 meters and change direction by 1 degree (when the front wheels change direction by 0.5 degrees to the right and the rear wheels change direction by 0.5 degrees to the left). However, a car is not as safe as it is when traveling in a straight line, and its ability to prevent rollovers during corrections is more than worth its salt, especially on expressways.
