Abstract
The utility model relates to an automobile safety device and in particular relates to a safety device used for preventing serious tilt of an automobile after tire burst, which comprises a wheel disc detachably fixed on a wheel hub of the automobile. The outer ring of the wheel disc is round, and the outer diameter of the wheel disc is bigger than the outer diameter of the wheel hub and smaller than the outer diameter of a charged tire under normal internal pressure so as to avoid serious tilt after the tire installed on the wheel disc bursts. The safety device is installed on the wheel hub, and in the case of tire burst, the safety device can substitute the tire to support the automobile, thus avoiding unnecessary loss and casualty caused by sudden tilt of the vehicle due to tire burst. The safety device can also substitute the tire to run for a stretch until the vehicle reaches a safe parking place to replace the tire or wait for rescue.
Description
Technical field
The utility model relates to a kind of automobile erecting device, relates in particular to a kind of automobile at the safety device of back knockdown of blowing out.
Background technology
The tire of automobile is generally rubber and constitutes, and inside is filled with certain gas, can support car body and in ground surface, in case the bearing the pressure that surpasses its load or meet with external object when puncturing of tire, the then phenomenon that will blow out.This phenomenon no matter occur at a high speed or the street on all be and dangerous, particularly occur in front-wheel, the run-off the straight of one side of vehicle owing to moment loses support, the vehicle that makes at high speed uplink is out of control most probably and rush at a high speed such as relative track, massif etc., the vehicle of exercising on the street very likely knocks other vehicles or the pedestrian who is exercising, cause damage always, even cause casualties.
Summary of the invention
In order to address the above problem, the utility model provides a kind of simple and reasonable, safety device of preventing knockdown behind the automobile flat tire.
To achieve these goals, the utility model is mainly solved by the following technical programs: a kind of safety device that prevents knockdown behind the automobile flat tire, this safety device comprises the dismantled and assembled wheel disc that is fixed on the wheel hub, the outer ring of wheel disc is circular, the external diameter of wheel disc is greater than the external diameter of wheel hub external diameter less than inflation back normal air pressure tire, to prevent knockdown behind the tyre explosion that this wheel disc is installed.
The cross-sectional plane of above-mentioned wheel disc is shape ringwise.
The inner ring of above-mentioned wheel disc is provided with connecting strap.
The other end of above-mentioned connecting strap is provided with reinforcing pad.
The madial wall of above-mentioned wheel disc is provided with collar.
The utility model is installed on the wheel hub, under the situation that tire is blown out, the safety device can replace the tire support vehicle, avoid causing unnecessary loss and personal casualty, and can also substitute vehicle and continue to exercise stretch to the local changing of tire of emergency or wait for rescue owing to tyre burst makes the vehicle immediate inclination.
