Description
[technical field]
The present invention relates to a kind of vehicle tyre runflat device, especially relate to a kind of vehicle tyre runflat air pressure automatic balancing arrangement.
[background technique]
Why automobile flat tire is all in summer, and why seldom blow out winter.A very important problem is exactly temperature, and temperature rises and can make inside tires gas meet thermal expansion, causes that tire pressure is too high blows out.Tire has three air pressure, one is that (car inside door handle or the mailbox of each car cover the standard atmosphere pressure that indicates tire to standard atmosphere pressure, standard atmosphere pressure adds that 30 % of standard atmosphere pressure are the safe air pressure of tire, tire pressure exceeds the limit air pressure that safe air pressure is exactly tire, once tire pressure surpass tire bear the air pressure limit, tire has the possibility of blowing out at any time.
Existing air pressure of automobile tire automatic monitor system (TPMS), mainly be divided into two types: a kind of is indirection type TPMS, its wheel speed sensors by automobile ABS (automatically anti-lock braking system) comes the rotating speed difference between the comparative tire, to reach the purpose that monitors tire pressure, its shortcoming is that the situation that can't surpass 100 kilometers/hour to situation and the speed of two above tires while deficencys is judged.Another kind is direct-type TPMS, it utilizes and is installed in the air pressure that each baroceptor take lithium ion battery as power supply of taking turns tyre cavity is directly measured tire, and be transmitted on the monitor unit that is installed in bridge by wireless-modulated, grasp the air pressure situation of each tire.Too low or when seepage was arranged, system will automatic alarm when tire pressure.
Existing air pressure of automobile tire commonly used all can not automatically adjust both at home and abroad.When automobile running, because temperature raises, can make the inside tires air pressure increase by 10%---20%.When the foreign material such as it is nervous that tire texture often keeps, and tire is subjected to wound easily, the stone on impact road surface or the scraggly road surface of process, the moment of stress concentrates and blasts.
[summary of the invention]
In order to overcome the deficiency in the background technique, the present invention discloses a kind of vehicle tyre runflat air pressure automatic balancing arrangement, by increasing pressure relief device of the present invention, so that the automobile of running at high speed utilizes automatic decompression device of the present invention that unnecessary air pressure is released, realized the effect of runflat.
For achieving the above object, the present invention adopts following technological scheme:
