Description
Technical field
The utility model belongs to the particular pressure switch of a kind of many grades of pressure switches and high pressure automatically unloading.
Background technology
Along with the fast development of highway, the speed per hour of vehicle is also in continuous lifting.Yet vehicle tyre was inflated foot and can be produced following defective when running at high speed:
1. easily produce the crown rapid wear, cause tyre life to shorten;
2. owing to the relative friction of tire, tyre temperature is risen, cause HTHP, the serious accident that happens occasionally and blow out with ground.
Yet tyre underpressure, its side easily produces fatigue wear, and long-term the use makes the tire premature aging, simultaneously, increases with contact resistance of ground, and oil consumption increases, and can lead to a disaster when serious.
Therefore, the tire pressure of appropriateness is one of the safe operation of support vehicles and the important measures that improve tire useful life, and also the monitoring system of tire will become one of important setting of car load configuration thus.
At present, tire monitor system roughly has following three class formation forms:
(1) sensitive switch that will monitor tire pressure is selected the version connect with tire air inlet
The defective that this version exists is: this covering device or the part that must will connect with valve inside during inflation are pulled down, and after inflation finishes, are installed again, and so not only time-consuming and cost improves; The wheel end (be tire side fixedly the metal dish of cover tire on) that exposes that pressure monitor is installed on wheel rim damages outward appearance easily; Continuous lifting along with the speed of a motor vehicle, supporting tyre valve core exposed junction is all shorter, and quality is little, to avoid the fatigue wear of valve inside when running at high speed, now if a microswitch or things such as miniature transmitter or connecting tube are installed outside valve inside, make in running at high speed, under the centripetal acceleration effect, can aggravate the fatigue wear of valve inside, will shorten the useful life of valve inside greatly.
(2) tire pressure detects and triggers sensitive switch when having selected gas leakage for use, with the version of wireless signal transmission
This version has tangible hysteresis effect.For example, when the speed of a motor vehicle at 120 kilometers/hour, a front tyre HTHP is blown out, instantaneous, tire is reported to the police from the 1.6kgf/cm2 that 3.8kgf/cm2 (is example with the car) drops into setting, may be when reporting to the police, pressure has been zero, and the driver does not in time take measures just to have collided or knock the traffic accident of safety barrier.
(3) more tire monitor system has all been selected the version of wireless transceiver system for use
This version makes the energy consumption of the detection transmitter module (if words of real-time monitoring) that is installed on the tire bigger, more existing tire pressure testing products have been selected import high power capacity lithium battery for use, nearly hundred yuan/to keep longer service time, the expense that four wheels change primary cell is higher, and obviously use cost is higher.
