Description

A SEALING PAD FOR PREVENTING AIR LEAKS FROM A VEHICLE TIRE Technical Field
The mechanical engineering related to a sealing pad for preventing air leaks from a vehicle tire. Background Art
Due to the constantly increasing number of motorcyclists and according to the collected data, it is found that the most common problem faced by the consumers or the motorcyclists is air leakage from a tire. To address the aforementioned problem, the invention, therefore, will focus on the inner tube, because of the inner tube acting as an air confinement, in particular, of the motorcycle tire which contains an inner tube. The most common problem encountered by the users is the problem of the air leakage from the inner tube which is caused by several possible reasons, such as a sharp object penetrating through tire, the tire friction, or inner tubes degeneration, etc. In the event of the air leakage from a tire, the users need to have the inner tube patched or replaced. According to the aforementioned problem, it is found that the average life span of the inner tube is approximately 6 - 8 months. Due to its non-reusable and non-recyclable condition, these damaged inner tubes cause waste problem. With this regard, the concept of inventing the novel products is initiated. That is the sealing pad for preventing air leaks from a tire that can confine the air better than or equivalent to the inner tube, but easier to use, with lesser risks of air leakage during its use, and has longer life span.
Summary and Object of the Invention
A sealing pad for preventing air leaks from a vehicle tire according to the present invention is composed of an elastic material, wherein the sealing pad is formed or molded into a cylindrical loop with a diameter corresponding to diameter of circumferential surface of wheel drum, and the surface area of the sealing pad has a width corresponding to entire surface size of wheel drum from one side of rim to the other side of wheel drum rim. An air filling valve is placed in the middle of surface area of the sealing pad and is attached to the sealing pad as one unit., wherein the air filling valve is inserted via a through hole of said wheel drum to fill air into a vehicle tire; and the sealing pad is placed between the wheel drum and the vehicle tire. The sealing pad is covered on the entire surface from one side of wheel drum rim to the other side of wheel drum rim, and both sides of the vehicle tire superimpose the area of both rim sides of the sealing pad. Therefore, the surface area of the sealing pad is compressed between the wheel drum and the vehicle tire to allow the sealing pad to do its job for preventing air leakage from the vehicle tire when filling air into the vehicle tire.
An object of this invention is to provide a sealing pad for preventing air leakage from a vehicle tire. When air is filled through the sealing pad, pressure inside the vehicle tire will be created. Then, the inside pressure causes vehicle tire to inflate, pushing the sealing pad against entire surface of the wheel drum; thus preventing filled air from leaking out. When in use, the weight of the vehicle pressuring on the tire will change the volume inside the vehicle tire. This results in increasing pressure inside the vehicle tire. Thus, the compression between the vehicle tire and the sealing pad will be increased, enabling higher ability to confine air in the tire. In this regard, said sealing pad is adopted to replace inner tube because it is easier to use than the existing tires, as well as lesser risks of damage during its use.

Fig.1 and Fig. 2 illustrate a sealing pad for preventing air leaks from a vehicle tire according to the invention. The sealing pad (1) is formed of an elastic material, such as natural rubber or synthetic rubber. The sealing pad (1) is formed or molded to cylindrical loop with diameter corresponding to diameter of circumferential surface of wheel 102 of the wheel drum 101, and surface area 2 of the sealing pad 1 has a width corresponding to entire surface size from one rim side of wheel drum rim 103 to the other side of wheel drum rim 103 of the wheel drum 101. In the middle area of the surface area 2 of the sealing pad 1 , there is an air filling valve 3 attached to the sealing pad 1 as one unit, in which the air filling valve 3 is inserted via a through hole 104 of the wheel drum 101 to fill air into the vehicle tire 201.
The sealing pad 1 is placed between the wheel drum 101 and the vehicle tire 201 when vehicle tire 201 is mounted on wheel drum 101, wherein the sealing pad 1 is covered on entire surface from one rim side of wheel drum 103 to the other side of wheel drum rim 103 of the wheel drum 101, and both rim sides of the vehicle tire 201 are placed over the area of both sides of the sealing pad 1. Therefore, the surface area 2 of sealing pad 1 is compressed between wheel drum 101 and vehicle tire 201 to allow sealing pad 1 to do its job for preventing air leaks from vehicle tire when filling air into the vehicle tire 201. Referring to Fig. 3, it shows mounting of sealing pad for preventing air leaks from the vehicle tire, according to the invention, on wheel drum 101 and vehicle tire 201, wherein the sealing pad 1 is placed between the wheel drum 101 and the vehicle tire 201, the sealing pad 1 will cover entire surface from one side of wheel drum rim 103 to the other side of wheel drum rim 103 of the wheel drum 101. The air filling valve 3 of the sealing pad 1 is inserted via the through hole 104 of the wheel drum 101 to fill the air into the vehicle tire 201. Both rims of the vehicle tire 201 are placed over both sides of the sealing pad 1.
Referring to Fig. 4, it shows air filling into the vehicle tire 201 when the sealing pad for preventing air leaks from the vehicle tire, according to the invention, has been mounted on wheel drum 101 and vehicle tire 201. Filled air through air filling valve 3 of the sealing pad 1 creates the pressure inside the vehicle tire 201, wherein said inner pressure causes the inflation of the vehicle tire 201 , pushing sealing pad 1 against entire surface from one side of wheel drum rim 103 to the other side of wheel drum rim 103 of the wheel drum 101. This prevents the filled air from leaking out. When the vehicle is in use, the weight of the vehicle will change the inner volume of the vehicle tire 201, resulting in increasing pressure inside the vehicle tire 201. Thus, the compression between the vehicle tire 201 and the sealing pad 1 will be increased, enabling higher ability to confine air.
The Best Mode of Invention
As same as mentioned in Detailed Description of a preferred embodiment.
