Description

Tire burst two-piece type safety hub

Technical Field

The utility model belongs to the technical field of wheel hub makes, it relates to multiple tire safe wheel hub that blows out.

Background

In many traffic accidents, statistics have shown that 40% of the traffic accidents on highways are due to tire failure, with one term of flat tire accounting for more than 70% of the total number of accidents due to tire failure. Over 95% of vehicles have no precaution against high-speed tire burst, and the death rate of the burst tire is close to 100% when the speed per hour is over 140 kilometers. After sudden tire burst in high-speed running, the vehicle body is inclined and out of control, so that vehicle damage and human death accidents are listed as the accident leaders of the expressway, the tire burst accidents are high, the fatality rate is high, and the life and property safety of drivers and passengers is seriously threatened.

The common wheel hub is usually provided with bead seats at two sides of the wheel hub, and the beads at two sides of the tire are tightly sleeved on the bead seats under the action of air pressure, so that the tire cannot be separated under the blocking of the wheel rim. The middle of the tire bead seat is provided with a wheel groove for replacing a tire, and the tire bead is sunk into the groove bottom under the internal cutting action of the tire opener, so that the tire bead can be turned over a wheel rim to be taken out or sleeved.

When the tire is burst or the tire pressure is seriously reduced, the resistance of the tire to knocking off the rim is sharply reduced, the tire can be separated from the rim seat under the action of the deviation force, and the tire is separated from the hub. The wheel hub sinks to directly contact with the road surface after the tire loses the supporting force, and at the moment, the vehicle loses balance, so that the vehicle is out of control to generate serious phenomena of sideslip, side turning and the like. The tire wall after the tire is inflated is a main part for supporting the weight of a vehicle, and when the tire is punctured seriously, the tire wall usually has instant crack (the time is less than 0.1 second), and the tire can be separated from a hub, so that the tire loses the supporting force instantly. The vehicle running at high speed is out of control which can not be saved due to tire burst of the front and rear wheels. The tire burst is a very serious safety accident, and particularly the tire burst occurs on a highway.

The existing methods for dealing with flat tires are divided into four types: one is the so-called "runflat" technique of reinforcing the wall thickness of the tire, which can be done at the expense of tire shock absorption and ride comfort, and is inconvenient and costly due to the tire being too stiff when repairing and replacing the tire. Secondly, the automobile owner is helped to prevent the occurrence of tire burst in a tire pressure early warning mode, but the technology cannot play a role in the occurrence of accidents, and the tire burst happens instantly and causes are various, so that the problem of only tire pressure is limited. In addition, the technologies of electronic auxiliary braking, direction locking and the like on the tire pressure early warning device have high realization difficulty, poor reliability and high cost. Thirdly, install the bed hedgehopping device additional in wheel hub and increase the wheel hub diameter so that the wheel can support after the tire bursts and travel, this type of device not only can produce certain influence to dynamic balance, the stability of high-speed vehicle that traveles to install to the tire dismouting behind this type of device relatively complicated, cause the trouble to user's daily use maintenance, consequently can't promote on a large scale. Fourthly, a fixing ring is additionally arranged on the edge of the inner wall of the tire, so that the edge of the inner edge of one side of the tire is fixed with the hub, the tire does not fall off the hub due to the effect of the fixing ring when the tire is blown out, and the effect after the tire is blown out at high speed is also limited.

Disclosure of Invention

The utility model provides a simple structure, convenient installation and use and improved working efficiency for solving the technical problems existing in the prior art.

The utility model discloses a solve the technical scheme that technical problem that exists among the well-known technique took and be:

the utility model provides a two formula safety wheel hub of tire puncture, includes wheel hub, installs the tire on wheel hub, its characterized in that: the wheel hub adopts split type structure, interior hub and foreign wheel hub promptly, and interior hub and foreign wheel hub include the tire of normally traveling respectively and have the rib of splicing each other along interior position of interior hub outside and foreign wheel hub inboard inside, and the diameter of its outer wheel hub is greater than the diameter of interior hub, installs the shock attenuation tire in the outer lane of outer wheel hub, after the installation interior, foreign wheel hub forms overall structure.

The utility model discloses can adopt following technical measure:

the tire burst safety hub comprises a spoke and a rim, wherein the spoke comprises a spoke central disc; and the outer ring of the wheel rim is provided with a damping tire.

And reinforcing ribs which are spliced mutually are arranged between the inner hub and the outer hub.

After the shock absorption tire is installed on the outer hub, the radius of the outer wheel is 2cm-2.5cm smaller than that of the inner wheel.

The utility model has the advantages and positive effects that: because the utility model adopts the above technical scheme. 1. The problem that a vehicle with a burst tire can continuously and safely run for a certain distance at a certain speed due to the diameter difference between the safety device and the inner wheel at the instant of the burst tire is solved, and the safety device has a good protection effect on the air leakage, the air shortage or the over-low tire pressure of the tire. 2. When the wheels are scratched to the road teeth, the safety device can protect the normally running tire, so that the service life of the tire is prolonged. 3. In order to reduce the impact force, a high-strength shock-absorbing tire is mounted on the outer edge of the outer hub to reduce the impact force caused by tire burst. 4.
