ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The invention herein relates to a composite tire comprised of a rubber tire mounted over a rim having externally an assembly of cover tire that protects the tire from puncture and wear. Such composite tire offers greatly driving safety and effectively reduces the consumption of rubber in the production of tire. Thus it is both environmentally friendly, economical, and directly enhances the value of industrial application.
2. Description of the Related Art
The construction of regular tires comes in two styles. The first one, as shown in
FIG. 1
, is to mount rubber tire

directly; the second one is to mount a band of rubber over the rim, and then arrange a rubber tube inside for accommodating air. Given the excellent properties of traction, wear-resistance and elasticity of rubber material, the aforesaid tires are arranged in such a way that they are in direct contact with ground surface, and undeniably, provide considerable comfort, speed and safety in driving. But in practical application, such tire construction also have some shortcomings:
1. Rubber cannot fend off sharp objects. Thus tires made of rubber that is either directly inflated or inflated through a rubber tube inside are susceptible to puncture by screws, nails or other hard, sharp objects scattered on the roads where vehicles travel. Punctured tire endangers driving safety, particularly when the car is carrying heavy load or traveling in high speed that it may flip over due to instantaneous deflation of tire.
2. Regular tire, be it inflated directly or through a rubber tube, is made of rubber and steel wires. When its treads are worn to a certain extent, the entire tire must be scrapped without the possibility of retreading. The remaining rubber cannot be re-utilized either. Moreover, to give tire surface certain thickness and strength, treads cannot be made too deep to begin with, which tends to necessitate tire change more frequently.
3. Rubber is not prone to decay. Its recycling and re-processing are complicated, tedious and costly. Thus the majority of used tires are not recycled, but scrapped. They are often randomly discarded and left unattended that produces an adverse impact on the environment. The pool of standing water in the inner trough of tire provides ground for propagation of disease vectors.
Thus the construction of regular tires has some shortcomings that can be improved in practical application.
SUMMARY OF THE INVENTION
The objective of the invention herein is to provide a composite tire, wherein rubber tire mounted over a rim is arranged externally with a cover tire assembly; the cover tire is lined internally with a steel jacket and the use of such tire can remove completely the risk of puncture or total wear.
Another object of the invention herein is to provide a composite tire, wherein the cover tire is supported by the inflated tire after the assembly is mounted over the tire and in contact with the ground surface in rubber material that allows its usage by vehicles completely barrier-free (providing elasticity and traction). More so, when treads in contact with the ground surface are worn out, it is only necessary to replace the cover tire without changing the entire tire, making the use of tire more economical.
Furthermore, the invention herein aims to provide a composite tire wherein the lining of steel jacket inside the cover tire protects the tire surface from puncture and air leak. Such arrangement allows treads on the outer circumference of tire to be deeper and fully utilized, and naturally prolongs the service life of tire.
Another objective of the invention herein is to provide a composite tire wherein rubber on the surface of the cover tire is more fully utilized and easily scraped off after it is worn out that allows the steel jacket to be recycled and effectively reduces the use of rubber material, making the tire both environmentally friendly and economical. It is an improvement over tires of prior art where tires are randomly disposed that causes pollution to the environment and is prone to the propagation of vectors.
