Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tire pressure indicating means for a tubeless tire which is used in a vehicle having a light load and is attached to a wheel. When the tire pressure falls below a normal value, the tire pressure indicating means is displayed to a driver. The present invention relates to a display means for notifying that a tire pressure has dropped due to air leakage or other reasons, and inspecting the tire or calling attention to take emergency measures.

[0002]

2. Description of the Related Art Most of tires used in general light-load vehicles are tubeless tires. A tubeless tire mounted on the outer periphery of a wheel of this kind has an airtight rubber sheet called an inner liner adhered to the inside of the tire, and a portion in contact with the wheel is formed with an annular edge portion. The gas filled in the tire can be safely sealed. Further, when a sharp foreign matter is stabbed into the tire, the inner liner shrinks to maintain the tire pressure, and it is possible to prevent the gas in the tire from suddenly leaking due to puncture or the like.

However, if the driver does not notice that the sharp foreign matter is stuck into the tire and the phenomenon of gas leakage occurs as described above, the tire pressure is extremely lowered after a certain amount of running. Excessive wear may occur on the tire, in which case the worn tire cannot be reused and the entire tire must be replaced.
Therefore, if a sharp foreign object pierces the tire and causes air leakage, there is a situation in which the tire must be replaced anew under the circumstances of the driver's carelessness or without any warning in advance. Not only increases the economic burden, but also becomes a great concern from the aspect of safety. Therefore, the driver needs to detect a decrease in tire pressure in advance.

[0004]

The present invention has been eagerly developed in view of the above situation in the conventional tubeless tire. That is, if the tire pressure is lower than the normal value, this is displayed to the driver at any time to inform that the tire pressure is decreased due to air leakage or other causes, or inspect the tire, or An object of the present invention is to provide a display means for calling attention to take emergency measures.

[0005]

A tire pressure indicating means for a tubeless tire according to a first aspect of the present invention comprises a wheel to which the tubeless tire is attached, a tire pressure detecting means, and a displaying means. The wheel detects the tire pressure at an appropriate position on the corresponding surface in contact with the tubeless tire,
A tire pressure detection unit having a wireless transmission function is provided, and the display unit has a function of receiving an information signal output from the tire pressure detection unit, and a display unit that displays information output from the tire pressure detection unit. And, it is provided at an appropriate place in the vehicle.

In the tire pressure indicating means for a tubeless tire according to a second aspect of the present invention, the indicating means according to the first aspect is provided at an appropriate place where a driver in the vehicle can visually observe, or on a dashboard.

In the tire pressure indicating means for a tubeless tire according to a third aspect, the display form of the indicating portion of the indicating means according to the first aspect is a tire pressure meter corresponding to four tires, or a light emitting diode or the like is used. The optical display method used, a warning sound method, or an identification method based on color change is selected.

BEST MODE FOR CARRYING OUT THE INVENTION The tire pressure indicating means for a tubeless tire according to the present invention comprises a tire pressure detecting means provided on a wheel to which the tubeless tire is attached and an indicating means provided at an appropriate position in the vehicle. This is for notifying the driver of an abnormality in tire pressure. In order to explain the structure and characteristics of the tire pressure indicating means of such a tubeless tire, specific examples will be given and described in detail below with reference to the drawings.

[0009]

BEST MODE FOR CARRYING OUT THE INVENTION As shown in FIGS. 1, 2 and 3, a tire pressure indicating means for a tubeless tire according to the present invention comprises a wheel (1) to which a tubeless tire (2) is attached, a tire pressure detecting means (3), And display means (4). The wheel (1) is provided with a tire pressure detecting means (3) at an appropriate position on the corresponding surface in contact with the tubeless tire (2). The tire pressure detection means (3) is a device that detects the tire pressure in the tubeless tire (2) and outputs the obtained information by a wireless transmission method. Further, the tire pressure in the tubeless tire (2) is displayed on a display means (4) separately provided at an appropriate place of the vehicle. That is, it may be provided at an appropriate location where the driver can see it or on the dashboard. In the embodiment, an example provided on the dashboard is disclosed. Further, the display means is provided with four tire pressure meters corresponding to the respective tires as disclosed in FIG. 3, and displays the tire pressure level. Therefore,
Regarding the tire pressure, the driver constantly obtains information as to whether all four tubeless tires (2) maintain normal tire pressure or whether one of them has abnormal tire pressure. You can As a matter of course,
The form of the display means (4) is an optical display system using a light emitting diode or the like, or a combination of display by a warning sound,
Alternatively, another format such as an identification method based on color change can be adopted.

Therefore, the sharp foreign matter of the tire gets stuck,
When the tire pressure decreases due to gas leakage of the tubeless tire (2), the tire pressure detection means (3) constantly detects the tire pressure and outputs the obtained information to the display means (4), so that the driver dashes. By the display means (4) provided on the board, the tire pressure abnormality can be known, and an effect of giving a warning to the driver can be obtained. In addition, the driver can detect an abnormal tire pressure of the tubeless tire (2) at an early stage, and can take emergency measures before causing excessive tire wear, resulting in excessive friction between the tire and the road surface. It is possible to prevent the wear due to, and to improve the traveling safety.

The above is a preferred embodiment of the present invention and does not limit the scope of the present invention. Therefore, any modifications and changes that can be made by those skilled in the art that have an equivalent effect on the present invention and are within the scope of the spirit of the present invention are included in the claims of the present invention.
