Safety tyre-burst brake deviation-rectifying system for automobile

Abstract

The invention is concerned with a safety brake error correction system when the vehicle's tire bursts. When the tire bursts, turn on the circuit to burst tire of the system by check and sending equipment and incepting and disposing equipment to burst signal, then close the liquid (gas) entering electromagnetic valve and open the liquid electromagnetic valve (exhaust valve) to break the trig pipe of burst tire and keep the brake into safety state and avoid the danger that driver stops to run in a wrong way in hurry. Control the automatic brake equipment or carry safety brake by driver will balance the huge resistance difference of tire burst among wheels. It removes the internal force when vehicle runs into a wrong way, and reminds driver by sound and light annunciator, open the left turning light, right turning light, double flash lights, emergency brake light and bugle of car to alarm cars and passerby. It relates to signal check of burst tire, sending equipment, incepting equipment, trig pipe equipment to break burst tire, controllable automatic brake equipment and sound and light alarm equipment.

Description

Technical field: [0001] The invention relates to an automobile tire blowout safety brake deviation correction system, in particular to a safety device which can automatically disconnect the brake pipeline of a blown tire wheel and apply brakes to all wheels that have not blown out when the automobile tire blows out technical background: [0002] In the process of high-speed driving, tire blowout is the most worrying and most difficult to prevent for all drivers. The incidence and severity of traffic accidents caused by car blowout increase with the increase of vehicle speed. One of the main causes of accidents. For solving this safety problem, people have designed devices such as automobile tire blowout safety device and automatic brake, but do not fundamentally solve the problem, there are still two outstanding problems: the one, existing brake system and blowout automatic brake device are not enough.

Problems solved by technology

For solving this safety problem, people have designed devices such as automobile tire blowout safety device and automatic brake, but do not fundamentally solve the problem, there are still two outstanding problems: the one, existing brake system and blowout automatic brake device are not enough. It has the function of only applying braking force to all wheels other than punctured tires to eliminate the internal force of vehicle deviation. Therefore, when a car driving at high speed suddenly punctures, it cannot brake urgently. Once emergency braking is implemented in a hurry, the consequences will be more serious; The device that automatically warns approaching vehicles and pedestrians to pay attention to the danger avoidance device, while the driver instinctively focuses on controlling the direction, has no time to manually turn on the warning lights and honk the horn, and cannot fulfill the warning obligation to public safety

[0003] Chinese Invention Patent Publication No. CN 1669851A "hydraulic isolation oil cylinder and automatic emergency braking system for automobile tire blowout" uses a detection unit to pick up the tire blowout signal and transmits it to the servo unit to drive the brake unit to work. Emergency braking, but the braking force is also applied to the punctured wheel. Considering the complexity of the road conditions and the increasing speed of the vehicle, there is a certain danger to the high-speed car.

Both theory and practice have shown that it is not suitable to brake when a tire blows out in a high-speed car, because it will vibrate violently when the tire blows out, and the direction is unstable and difficult to control. The resistance of the tire suddenly increases sharply, which causes the internal force of the vehicle to deviate. If you brake at this time, the wheel with a punctured tire is very easy to brake due to the increase in friction, while the wheel without a puncture on the other side is relatively difficult to brake, and the vehicle deviates. The internal force of the car will continue to increase, and the risk of deviation will become more serious, and it is very easy to cause serious deviation and cause a crash or rollover
