Intelligent wheel anti-collision system

Abstract

The invention discloses an intelligent wheel anti-collision system, and belongs to the technical field of automobile safety. In order to timely increase the contacting area and friction force of a tire and a road surface during emergency braking at a critical juncture for improving the braking effect, according to the following adopted technical measures, a microphone, a Doppler detecting device and / or a distance measuring device are mounted on an automobile, the microphone, the Doppler detecting device and / or the distance measuring device are connected with a computer, and the computer is connected with a cover opening device; a pressure reducing valve communicates with an inner cavity of the tire and is mounted on a wheel hub of a wheel, an exhaust port of the pressure reducing valve issealed by an exhaust cover which can be opened, and an cover opening groove or other devices being facilitated for cover opening is machined in the exhaust port; the pressure reducing valve communicates with the inner cavity of the tire and is wrapped by a sealed container and is mounted on the wheel hub of the wheel; and the cover opening device is mounted on the circumference where the exhaust cover passes. According to the anti-collision system of the intelligent wheel, an exhaust device is mounted on the tire, air pressure of the tire can be lowered instantly under controlling of a personor a computer, and the contacting area of the tire and the road surface is increased greatly.

Description

technical field [0001] The invention belongs to a field of automobile safety technology. Background technique [0002] Long braking marks can always be seen on the road at the scene of a tragic traffic accident, which records information such as the starting point of braking and the speed of the car. But another piece of information it records has been ignored by people, that is, the misery and helplessness of the tires, which is caused by the high-temperature melting and falling off of the rubber of the tires during the high-speed and high-pressure friction with the road surface, and is bonded together with the road surface. . This phenomenon clearly shows that the contact area between the tire and the road surface is too small. Because the contact area between the tire and the road surface is too small, a small part of the rubber bears this huge friction. At the same time, the long braking marks also indicate that the braking effect is not good. The friction force betwe...

Problems solved by technology

However, reducing the air pressure of the tires will increase the driving resistance, increase fuel consumption and other problems, and also affect the service life of the tires. Obviously, the two are a pair of contradictions.
