AI Technical Summary

Technical Problem

Conventional height adjustment devices for vehicles are separate from the steering system and fail to address vehicle instability due to centrifugal forces during high-speed turns, leading to potential accidents.

Method used

An improved steering device integrates a weight, drive device, and gyro device to control vehicle body tilt by detecting vehicle speed and steering angle, using weights to counteract centrifugal forces.

Benefits of technology

Enhances vehicle stability during high-speed lane changes, reducing the risk of accidents by stabilizing the vehicle body against centrifugal forces.

Abstract

To provide an improved steering device with vehicle body control by a weight by combining the weight, a driving device, a gyro device, and a steering device.SOLUTION: Since a vehicle body tends to lean to the right due to centrifugal force when a steering wheel is turned to the left, the vehicle body is equipped so that the vehicle body is inclined to the left by moving a weight such as a battery for traveling to the left, and its angle is set to 1 to 30 degrees from a horizontal line with the right as a center. On the other hand, since the vehicle body tends to lean to the left due to centrifugal force when the steering wheel is turned to the right, the vehicle body is equipped so that the vehicle body is inclined to the right by moving the weight such as the battery for traveling to the right, and its angle is set to 1 to 30 degrees from the horizontal line with the left as the center. Also, a traveling speed, a gyro, and a steering angle are detected to adjust an inclination angle of the vehicle body.SELECTED DRAWING: Figure 7

Description

[Technical Field]

[0001] This invention relates to an improved steering device that combines a weight, a drive device, a gyro device, and a steering device, and that allows vehicle body control by weight. [Background technology]

[0002] Conventionally, vehicles equipped with height adjustment devices are used to restore the tilt of the vehicle body on rough roads or to restore the floating or sinking of the front of the vehicle during sudden acceleration or deceleration, and are independent devices separate from the steering system. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Utility Model Application Publication No. 03-113211 [Patent Document 2] Patent Application No. 2019-140295 Summary of the Invention [Problem to be solved by the invention]

[0004] This had the following drawbacks: Conventionally, vehicles equipped with height adjustment devices are used to restore the tilt of the vehicle body on rough roads or to restore the floating or sinking of the front of the vehicle during sudden acceleration or deceleration, and are independent devices separate from the steering system. The law of inertia applies to objects, and when a vehicle changes direction at high speed, it tilts significantly in the opposite direction, causing it to lose stability and resulting in traffic accidents such as slipping and rolling over. The present invention has been made to eliminate the above-mentioned drawbacks. [Means for solving the problem]

[0005] Now, let me explain the solution with reference to the diagram: (a) As shown in Figure 1, when the handlebars (1) are turned to the left, the body (2) tends to tilt to the right due to centrifugal force, as shown in Figure 2. Therefore, as shown in Figure 3, a weight (8) such as a running battery moves to the left, causing the body (2) to tilt to the left. The angle should be centered to the right and between 1 and 30 degrees above the horizon. (b) As shown in Figure 4, when the handlebars (1) are turned to the right, the body (2) tends to lean to the left due to centrifugal force, as shown in Figure 5. Therefore, as shown in Figure 6, a weight (8) such as a running battery moves to the right, causing the body (2) to lean to the right. The angle should be 1 to 30 degrees from the horizontal, with the left at the center. (c) As shown in Figure 7, the vehicle speed, gyro and steering angle are detected to adjust the tilt angle of the vehicle body. The present invention is an improved steering device with the above-mentioned configuration that controls the vehicle body using weights. [Effects of the Invention]

[0006] Therefore, a car equipped with this device can be driven with several times greater stability than a conventional car when changing lanes at high speeds, against the harmful centrifugal forces acting on the car body. [Brief explanation of the drawings]

[0008] Hereinafter, an embodiment of the present invention will be described. Now, let me explain the solution with reference to the diagram: (a) As shown in Figure 1, when the handlebars (1) are turned to the left, the body (2) tends to tilt to the right due to centrifugal force, as shown in Figure 2. Therefore, as shown in Figure 3, a weight (8) such as a running battery moves to the left, causing the body (2) to tilt to the left. The angle should be centered to the right and between 1 and 30 degrees above the horizon. (b) As shown in Figure 4, when the handlebars (1) are turned to the right, the body (2) tends to lean to the left due to centrifugal force, as shown in Figure 5. Therefore, as shown in Figure 6, a weight (8) such as a running battery moves to the right, causing the body (2) to lean to the right. The angle should be 1 to 30 degrees from the horizontal, with the left at the center. (c) As shown in Figure 7, the vehicle speed, gyro and steering angle are detected to adjust the tilt angle of the vehicle body. When a car is fitted with this device, the weight (8) moves from side to side, causing the body to tilt in proportion to the speed, gyro and steering angle, giving the car what is commonly known as traction.
