Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention provides a lateral groove in a traveling division zone such as a center line or a lane on an ordinary road or an expressway,
The present invention relates to a device for generating a vibration sound with a tire running on a lateral groove and forming the lateral groove.

[0002]

2. Description of the Related Art In general roads and highways, especially on driveways with many curves, on the road surface at a curved portion, a number of fine vertical grooves extending along the traveling direction over almost the entire road surface or lateral grooves perpendicular to the traveling direction. Is provided
The prevention of the hydroplane phenomenon is performed by preventing the sideslip of the tire, enhancing the braking effect, and preventing the formation of a partial pool of water. When the vehicle travels in this groove portion, fine vibrations are generated in the tires, which not only give small vibrations to the vehicle body and the driver but also generate noise, which has the effect of alerting the driver and the effect of preventing drowsy driving.

On the other hand, white lines are marked at regular intervals between the driving lanes and on the shoulders of highways including general roads and the Shuto Expressway, and when the vehicle runs on these roads, there is a slight bump on the white lines. There are those that generate vibration noise on the tire, and those that stick the white line material with many round protrusions on the surface of the material that becomes the white line on the road surface, and when you run on it, vibration noise is generated, Vibrating noises are usually experienced by the driver to help him know that he is turning away.

By the way, in the grooving work for forming a groove on the road surface, a large number of diamond blades having a diameter of 20 to 30 cm and a width of about 5 mm are piled up at an interval of 10 to 20 mm on the lower part of the work vehicle to make the total width of 1 A cutting wheel of about 1 to 1.5 m is provided separately from the running wheel, and the cutting wheel is rotated to a depth of 3
The cutting work is performed by running the work vehicle at a low speed while making a cut of 5 mm or 5 mm and spraying the cooling water to the cut portion.

[0005]

Grooving of a vertical groove or a horizontal groove on a road surface is usually performed on a curved portion, and in addition, it is necessary to call a driver's attention to a slope, a dangerous place, or a driver. It is only done for a specific range, such as a place with. Therefore, from the viewpoint of preventing the driver from falling asleep, it was effective only in the portion where each groove was applied.

The marking of broken white lines between the driving lanes and the shoulders of the road at regular intervals is for the purpose of identifying the driving range of the driver, and a slight vibration is given to the vehicle running on it. However, it is not possible to give a clear warning to the driver, and in particular, it is not possible to cope with a dozing driving.

On the other hand, a working machine for grooving a road surface is designed to rotate a large number of the diamond blades, which are stacked on an axis at right angles to the running direction of the vehicle, so that the running of the worker makes the cutting progress. When forming a vertical groove on a road surface, a long section with a width of about 1 to 1.5 m is cut, and this is repeated in parallel to perform a grooving operation for a predetermined road surface area. Since the working machine has such a configuration, when forming the lateral groove of the road surface, the working vehicle is run in a direction perpendicular to the traveling direction of the road to perform cutting work by 1 to 1.5 m, and Since the work vehicle is moved 1 to 1.5 m in the traveling direction, the same work is performed again, and this process is repeated, the lateral groove cannot be formed efficiently.

Therefore, the present invention warns the driver of the vehicle that the vehicle body is out of the traveling boundary area by vibrating the grooves and tires of the road surface together with the white line, and in particular, prevents accidents due to drowsiness. At the same time, it is an object of the present invention to provide a device for easily and efficiently forming the groove.

It is possible to warn the driver of the vehicle that the vehicle body deviates from the traveling boundary area along with the white line by vibrating and vibrating the groove and tire of the road surface, and forming the groove easily and efficiently. It was made possible.

[0010]

Since the present invention is configured as described above, when the vehicle travels on the lateral groove formed along the vehicle traveling direction in the portion that divides the vehicle traveling boundary area, the vibration of the vehicle is caused by the contact between the tire and the lateral groove. A sound is generated to give a warning to the driver by vibrating sound that the driving vehicle is out of the traveling boundary area and is dangerous.

When forming the lateral groove, the heater provided in front of the work vehicle is operated to heat the road surface to soften the road surface such as asphalt and white lines, and the work vehicle is provided to provide the rear portion of the heater. By placing the roller on a softened road surface and running the vehicle while pressing the roller against the road surface, the lateral groove forming projection formed on the outer periphery of the roller bites into the road surface and the lateral groove is imprinted on the road surface. A stable lateral groove is formed by the cooling.

It can also be configured as follows.

[0029]

Since the present invention is constructed and operates as described above, if the driver tries to get out of the traveling zone without knowing it while the vehicle is traveling, the tire runs on the lateral groove formed in the vehicle traveling boundary area. As a result, vibration noise is generated from the tire,
Along with the white line, the driver is warned, and the vibration of the tire causes the vehicle to vibrate, so that the driver can be awakened by vibrating even when the driver is asleep.

Further, when forming the road surface groove, by using the forming device as described above, it is possible to accurately and easily perform any length and any curve only by causing the work vehicle to travel along the road. Since the lateral groove forming work can be performed efficiently and the work vehicle can travel only on a part of the road surface, it is possible to reduce the closed area during the work.

Further, since it is not necessary to cut the road surface, it is not necessary to use an expensive diamond blade, the lateral groove can be formed at a low cost, and cutting powder is not generated, so that the surrounding environment can be damaged. In addition, since the material melted in the cooling water at the time of cutting does not pollute the surroundings such as the road surface and does not emit noise such as cutting noise, it is possible to perform work even in the city at night.
