Air relief valve for electrically controlled tire explosion avoiding system

Abstract

The invention relates to an air relief valve, in particular to an air relief valve for an electrically controlled tire explosion avoiding system. The air relief valve comprises a valve body and a valve core, wherein the valve body is used for fixing the air relief valve onto a tire, and facilitates the arrangement of the valve core at the same time; the valve body is provided with a notch; the valve core has a hollow structure provided with an exhaust channel, and the valve body rotatably sleeves the valve core; a valve core body is provided with a damage piece at the position relative to thenotch; the air relief valve also comprises a thermal sealing plastic packaging cover; the notch and the damage piece are also sealed together by the thermal sealing plastic packaging cover, so that adamage type sealing structure is formed. Under normal circumstances, the air relief valve realizes good air seal by means of the thermal sealing plastic packaging cover; when deflation is needed, thevalve core of the air relief valve is tried to be rotated, so that the thermal sealing plastic packaging cover is destroyed by using a damage head, and the tire pressure is accordingly reduced rapidly; therefore, the working states of wheels at the left and right sides of a car is enabled to be consistent rapidly, and the control ability is recovered.

Description

technical field [0001] The invention relates to an air release valve, in particular to an air release valve used in an electronically controlled tire blowout avoidance system. It is suitable for medium and high-end passenger cars equipped with tire pressure measurement system, steering wheel angle sensor and wheel speed sensor. Background technique [0002] A tire blowout during driving will cause serious traffic safety accidents, because the tire blowout almost always occurs during high-speed operation, especially when the steering wheel blows out, and the body loses balance due to the inclination of the car body. The rolling radius of the left and right steering wheels and The assisting force between the tire and the ground is quite different. At this time, the car almost loses its steering control ability and serious deviation occurs. If it is forced to brake, it will aggravate the deviation. If it is forced to correct the direction, it will increase the possibility of th...

Problems solved by technology

The former requires experienced and calm drivers to achieve limited results. The latter has so-called anti-explosion tires and other similar technologies to increase the rolling radius of the wheel after a puncture. It is only used on very limited vehicles and can only reduce the degree of danger to a limited extent.
