Abstract

PURPOSE:To reuse a tire until the lives of parts except a crown part are exhausted by exchangeably forming the crown part. CONSTITUTION:A tire is composed of fundamental parts and an exchanging crown part. The fundamental part consists of the crown part, a shoulder part, a side part and a bead part. A usually worn part is the crown part, and the shoulder part, the side part and the bead part have a longer life in comparison with the crown part. In this invention, since a worn part is the exchange crown part, the tire can be reused until the lives of the shoulder part, the side part and the bead part are exhausted by exchanging the crown part for reusing the tire. In addition, since only the exchanging crown part can be individually manufactured, the tire can be easily processed when a foreign matter enters the crown part, and the performance of the tire can be improved.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention extends the life of the entire tire by replacing the crown portion of the tire.

[0002]

2. Description of the Related Art Since a tire is made as an integral type, even if the basic part, shoulder part, side part and bead part can be used when the crown part is worn out, it is not only wasteful but also wasteful. There was a problem with the processing of old tires.

[0003]

As described in the prior art, there is a problem that the base portion, the shoulder portion, the side portion and the bead portion cannot be used even if the crown portion is worn.

[0004]

In order to achieve the above object, the tire according to the present invention has a structure in which the crown portion can be exchanged, and by exchanging the crown portion, the tire can be reused until its life reaches another portion. It is possible to do

[0005]

[Function] Since it is possible to manufacture only the crown part by replacing the crown part, the crown part can be easily processed such as mixing foreign matter into the crown part, and the tire can be reused at low cost. The transportation and storage costs are reduced, and the life of the tires is extended, so that the number of old tires is reduced and the amount of old tires to be processed is reduced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a diagram showing an example of the present invention in a tire cross section and showing names of parts for explaining the present invention. FIG. 2 is a diagram showing the meshing of the present invention.
Use them by meshing so that points and A'points and B and B'points match. With this structure, it is possible to identify one point on the crown or the basic part, set a mark or groove there to facilitate the cutting of the reinforcing material of the replacement crown at the time of replacement, and transmit the force more efficiently. Is possible. FIG. 3 shows a perspective view of the entire replacement crown portion in the present invention. The mounting of the crown portion in the present invention will be described. The tire is evacuated and the circumference of the basic part is bent to insert it inside the replacement crown part. At this time, the heat generated between the replacement crown part and the basic part at the contact part between the replacement crown part and the basic part. In order to prevent heat and improve heat conduction, an adhesive bonding material is attached. After mating, the tire is integrated with the tire by injecting air into the tire and returning the concave curve of the basic part to the original shape. FIG. 4 is a diagram showing four connections of replacement crown portions in the present invention, and it is possible to form a replacement crown portion having a strength capable of resisting a lateral force of a tire. FIG. 5 is a perspective view of a cross section of an embodiment of the present invention. FIG. 6 is a perspective view of a cross section of an embodiment of the present invention, showing that the replacement crown portion is designed to be wider than the basic portion to reduce wear of the shoulder portion.

[0007]

As described above, by exchanging the crown portion, the life of the entire tire is extended, and it becomes possible to manufacture only the crown portion, so that the design of the crown portion and the selection of materials can be further expanded. The performance can be improved, the storage cost and the transportation cost can be reduced because only the crown part needs to be stored and transported, and the life of the tire as a whole is extended, so that the throughput of the old tire is reduced.
