Description

Novel automobile tire free of worry during tire burst

The technical field is as follows:

the utility model relates to a motor vehicle safety equipment field of traveling, concretely relates to carefree automobile tire of blowing out, more specifically say and relate to and avoid the vehicle to lead to the emergence of the serious accident of car destruction people's death after the sudden blowing out in the driving, effectively guarantee the safety of people's lives and property.

The background art comprises the following steps:

various vehicles are inevitably subjected to tire burst accidents during running, and the tire is punctured due to over inflation, insufficient air pressure or worn and aged tires and sharp objects pressed on the road surface. Once a tire burst accident happens to an automobile running on a highway, a driver is mishandled or lacks control experience, the automobile can be out of control, deviated, rushes out of a lane or even overturns, rushes out of a guardrail to the opposite lane and collides with the automobile running in the reverse direction, the automobile is damaged if the automobile rushes out of the guardrail, personnel on the automobile are injured, huge economic loss is brought, and serious people endanger life and cause irrecoverable serious consequences. There are data indicating that the rate of tire burst accidents occurring on the highway is 34% of all accidents, indicating that the consequences of a tire burst are very severe. The existing explosion-proof tire is improved and reinforced at two sides of an outer tire, a rubber structure of a tire side wall is enhanced on the basis of a common radial tire, steel fiber cloth is additionally attached to the wall to improve the strength of the tire side wall, and the tire wall is thicker, harder and heavier. The wheel is supported by the tire sidewall to run for a distance after the tire is punctured. However, the tyre is hard, the shock absorption effect of the tyre is weakened, the road noise is much larger, the driving comfort is reduced, the manufacturing cost is high, and the tyre is generally configured only on high-grade vehicles.

The utility model has the following contents:

the invention aims to overcome the defects that when a tire burst accident occurs, the spare tire in the outer tire of the vehicle instantly falls to the ground and immediately plays a role in playing a role of the spare tire to play a role in the normal running of the vehicle, so that the vehicle cannot deviate or slightly deviate and is controlled by a driver to correct the deviation, the vehicle cannot collide with a guardrail and other vehicles or cause great loss caused by overturning and the like, and the problem of life threatening does not exist.

The principle of the technical scheme of the invention is as follows: the bicycle tire or the motorcycle tire additionally arranged in the outer tire does not work in normal running because the bicycle tire or the motorcycle tire is not attached to the outer tire and is in a suspended state about 25mm away from the outer tire surface, only when the tire is blown, the bicycle tire or the motorcycle tire can instantly fall to the ground and is in contact with the road surface, the outer diameter of the bicycle tire or the motorcycle tire is not much smaller than the outer diameter of the tire in normal running (about 30-40 mm), the ground clearance is generally only about 10-20 mm, the bicycle tire or the motorcycle tire can still smoothly transit after falling to the ground to keep stable forward rolling to continue running of the vehicle, and a driver can stop and change the tire to an emergency lane or a nearby service area when hearing the noise of the blown tire and feeling that the tire slightly shakes. The added tyre can be a solid rubber tyre. The bicycle tire is provided with a steel ring, 2 steel rings are stressed simultaneously, the steel rings are connected by adopting a steel plate strip, a plurality of steel plate strips are arranged at equal intervals along the circumference of the steel ring, and the steel plate strips are welded on the steel ring. The screw rod is vertically connected and tightly pushed between the steel plate strip and the automobile hub, a plurality of bolt holes are formed in corresponding positions on the hub, an aluminum alloy sleeve is welded in the hole opening in a centering mode, and the screw rod of the full-length bicycle wire extends to the center of the steel plate strip connected with the bicycle steel ring until the screw rod is tightly pushed by screwing the sleeve. The height of the sleeve is 10-15mm lower than that of an outer wheel rim of the automobile hub, so that the principle of mounting the outer wheel tire is not influenced. The force transmission path is as follows: bicycle tire-steel rim-steel plate strip-screw-rod-automobile hub. A plurality of rubber positioning blocks are arranged in the gap between the two sides of the bicycle tire and the outer tire at equal intervals to ensure that the rubber positioning blocks are arranged in the outer tire in the middle, and the rubber blocks are adhered to the side wall of a bicycle steel ring by glue. For truck tires with larger load capacity and size, 2 bicycle tires can be changed into 1 or 2 motorcycle tires, and the number of the tires is determined by ensuring that the bearing capacity of the tires meets the requirement of the large-tonnage truck.
