Device for keeping automobile body stable after tire burst

Abstract

The invention discloses a device for keeping an automobile body stable after tire burst. The device comprises a hub, a tire, a tire pressure monitor, a controller, a gas supply device and an auxiliary supporting device, wherein the tire is mounted on the outer circle of the hub; the auxiliary supporting assembly is arranged in a gap between the outer circle of the hub and the tire and comprises a supporting ring and a plurality of supporting assemblies which are uniformly distributed along the supporting ring; the tire pressure monitor and a starter of the gas supply device are electrically connected with the controller separately; and the tire pressure monitor can monitor a tire pressure change range in real time. After tire burst of an automobile, signals are transmitted to the controller, the controller transmits signals to the starter of the gas supply device, the gas supply device inflates the auxiliary supporting device, then the auxiliary supporting device can support the automobile body, the circumstance that the automobile body is out of balance due to impact caused by instantaneous distance from the automobile to the ground during tire burst is avoided, the heights of tires on two sides of the automobile can be stabilized in time, and the overall running balance of the automobile is guaranteed.

Description

technical field [0001] The invention relates to a safety device for an automobile, in particular to a device for maintaining the stability of the vehicle body after a tire blows out. Background technique [0002] Overheating of tires caused by high-speed driving, increased tire pressure, or punctured tires by sharp and hard objects may cause car tires to blow out. Car tire blowout accidents have always been one of the most troublesome problems in the automotive industry and transportation departments. When a tire blows out, The whole vehicle will instantly tilt to the side of the punctured tire, and when the vehicle is traveling at a speed above 60km / h, once a punctured tire occurs, the driver has almost no time to react, and the thickness of the tire becomes smaller instantly, which directly leads to an instantaneous The impact of the drop from the ground will cause the body to lose balance, and the vehicle will instantly deviate from the original route and even be overturn...

Problems solved by technology

[0002]The overheating of tires caused by high-speed driving, the increase of tire pressure, or the puncture of tires by sharp and hard objects may cause car tire blowouts. One of the most troublesome problems of the traffic department, when a tire blows out, the whole vehicle will instantly tilt to the side of the blown tire, and when the vehicle is traveling at a speed above 60km / h, once a wheel blows out, the driver has almost no time to react , the thickness of the tires becomes smaller instantly, which directly leads to the impact of the instantaneous distance from the ground to the high-speed driving body, and then the body loses its balance. Once a tire blowout accident occurs on a motor vehicle traveling on the road, the vehicle will be damaged at the slightest, and the car will be destroyed or even cause a chain accident, resulting in heavy losses.

[0003] In the prior art, in order to avoid the vehicle out of control caused by the vehicle tire blowout, the following technical solutions are mainly included: one is to set a safety device on the wheel hub so that when the explosion occurs After the tire, the safety device can serve as an auxiliary support to reduce the instantaneous drop from the ground caused by a unilateral tire blowout, but the height difference between the safety device and the tire is too large to assist after a blowout Support function, if the height difference is too small, it will increase the weight of the wheel hub and affect the flexibility of the vehicle. It is actually very difficult to inflate a leaky tire to the air pressure that can support the vehicle body in a short period of time; one is to use the active safety control technology of the vehicle to deal with the sudden tire burst when the vehicle is driving at high speed. Rely on the body dynamic stability system carried by the vehicle to indirectly deal with sudden tire blowouts, but this technology has high application costs and poor applicability
