Abstract

The utility model discloses a mutual spare inflatable tire and rim thereof, which comprises a tire body 1, a cavity 2 and a rim 5, wherein two or more than two completely independent and parallel circular cavities 2 are formed inside the tire body 1 under the action of the tire body 1 and the rim 5, the cavities can be used for placing inner tubes and can be filled with gas to be made into a tubeless tire, and when one of the cavities bursts or loses the air, the other cavities can keep normal air pressure to ensure the normal work of the tire. The cavities independent of each other are in a common utilization relationship and a standby relationship, which is very important for dealing with accidents.

Description

Standby each other inflatable tire and wheel rim thereof

The utility model relates to a kind of tire, particularly a kind of rubber tire; The utility model also relates to the wheel rim that a kind of kissing of tire is therewith joined.

As everyone knows, has only an inflatable cavity in the cross-sectional plane of existing inflatable tire, this structure, no matter be tube-tyre or tubeless tires, as long as explosion or disappointing phenomenon take place in its arbitrary position, will cause whole tire normally not use, the generation of this situation, gently then make troubles to work, heavy then cause major accident.With the automobile is example, and " expressway safety driving guide " book that China Machine Press publishes in December, 1997 has one " vehicle on highway reason cartogram " to show that burst tyre accounts for the vehicle reason and causes 56.4% of traffic accident for the 106th page; The 127th page with " from the statistics of domestic tens main traffic accidents, the traffic accident that tire fault causes almost accounts for the over half of traffic accident sum ", this shows the importance of tire.Present tire manufacturing only is to study, improve on the employed in the mill raw MAT'L, and on its geometry without any breakthrough.

Main purpose of the present utility model is to prevent burst tyre and the serious accident that causes, makes the user safer, convenient; The another one purpose is to realize two or more gas-filled cavity independently of the present utility model under the cooperation of this wheel rim.

For achieving the above object, technical solution adopted in the utility model is: in the inside of tire cross-sectional plane, be designed to the tire body be made up of two or more cavitys, these two or more cavitys are joined by the kiss of the geometric configuration of Outer Tyre and wheel rim and are realized.

Outstanding contributions of the present utility model are: when one of them cavity generation explosion or disappointing phenomenon, other cavity then can keep normal barometric pressure, can guarantee the normal operation of this tire; The utility model has only been done pioneering design on its geometry, its separate cavity is common utilization relation, be again mutual standby relation, this is very important for dealing with burst accident, has fundamentally guaranteed life and property safety in user and the surrounding environment.

Now in conjunction with the accompanying drawings the specific embodiment of the present utility model is further elaborated.

Accompanying drawing is the schematic sectional view of a kind of embodiment of the present utility model.

Now with the example explanation of being designed to of two cavitys:

By accompanying drawing as can be known, the utility model is made up of body 1, cavity 2, tyre bead 3 and the wheel rim 5 of Outer Tyre, because the effect of tire body 1, wheel rim 5 and ring washer 6, make the inside of tire body 1 form two independent, arranged side by side fully circular airtight cavitys 2, this cavity both can be laid tire inner tube, can fill with gas again and make inner tube free tire, valve can be drawn from the wheel rim of a side separately; In the groove 4 of tyre bead, tyre bead in the middle of it both can have been fixed can play sealing function again in the middle of ring washer embedded in the middle of on the wheel rim; Two cavitys have independently played the effect of two tires, because of factor incomplete same in many ways such as its physical property, air pressure, environment, thereby, explosion takes place simultaneously and the probability of the phenomenon of losing heart minimum; Wheel rim is to have increased middle ring washer on the basis of traditional wheel rim, realizes goal of the invention to cooperate the utility model.As needs, can be designed to a plurality of cavitys, principle is the same.

Claims

1, a kind of cover tire of standby inflatable tire each other is characterized in that: there are two or more circular cavities separate, arranged side by side (2) inside in tire body cross section (1);

2, the described tire kissing of a kind of and claim 1 wheel rim (5) of joining is characterized in that being made up of the back-up ring more than three or three (6).
