Description

Automobile tire with higher safety performance

Technical Field

The utility model relates to a tire technical field specifically indicates a higher automobile tire of security performance.

Background

The tire is an important component of an automobile, the current tire is usually a vacuum tire, a spare vacuum tire is arranged on the automobile, the spare vacuum tire needs to be replaced to continue driving under the condition that the tire is used for a long time or is pricked, the number of road traffic deaths continues to rise according to the report of the current situation of global road safety in 2018 of the world health organization (world health organization), 135 ten thousand deaths are caused every year, and the number of deaths caused by the direction failure due to the tire breakage on the expressway accounts for the majority. And the traditional vacuum tire has the following defects:

1. spare tires for automobiles are not changed by many people, particularly women;

2. the replacement of the spare tire at a high speed has great danger and has very high probability of causing rear-end collision or secondary damage;

3. the traditional tire has the risk of tire burst, and the direction is not easy to control and traffic accidents are easy to occur when the tire bursts;

4. if the air leakage of the traditional tire is not in time, the vacuum tire and the wheel hub are deformed and damaged, so that the unnecessary high cost for replacing the tire or the wheel hub is caused;

5. an automobile usually has only one spare tire, and if a plurality of tires are damaged simultaneously, the spare tire is not enough;

6. spare tires for automobiles are usually placed in the trunk of the vehicle, occupying storage space.

Therefore, a new tire with a safety spare tire, which has high safety performance and strong practicability, is urgently needed.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is to overcome above technical defect, provide the higher automobile tire of security performance to solve above-mentioned technical problem.

In order to solve the technical problem, the utility model provides a technical scheme does: the automobile tire with high safety performance comprises a hub and a vacuum tire mounted on the hub, wherein a boss is arranged on the periphery of the inner surface of the hub, a solid spare tire located on the inner side of the vacuum tire is sleeved on the periphery of the outer surface of the boss, connecting holes are fixedly connected to the lower ends of two sides of the solid spare tire, a threaded hole corresponding to the connecting hole is formed in the boss, and the solid spare tire is inserted into the connecting hole through a screw and is in threaded connection with the boss through the threaded hole 7.

Compared with the prior art, the utility model the advantage lie in: when the outside vacuum child blows out or leaks gas, inside solid spare tyre of fixing on wheel hub can play the supporting role the same with the tire, need not to change also can normal the traveling to the maintenance point of spare tyre, there is not the problem of changing spare tyre on the highway, it is comparatively convenient to use, need not join in marriage spare tyre in addition simultaneously, practice thrift the occupation space of trunk, when blowing out, the condition that the steering wheel is not good to be controlled can not appear, in addition even if a plurality of tires blow out or leak gas simultaneously, also can normally travel, the security performance is higher, the practicality is stronger.

As an improvement, a cast integrated structure is arranged between the boss and the hub, so that the stability is high, and the large-batch production can be realized.

As an improvement, the damping holes are formed in the periphery of the two sides of the solid spare tire, so that the damping effect of the solid spare tire is improved, and the comfort of drivers and passengers is improved.

As an improvement, the outer surface of the boss is positioned outside the hub, and the part of the hub provided with the solid spare tire is higher than the part of the hub provided with the vacuum tire, so that the solid spare tire is not split and spliced on the boss during installation and can be directly sleeved on the boss with an integral inner diameter, and the assembly is more convenient during production.
