Abstract
The utility model relates to a wired pressure measurement-based central tire inflation and deflation device. The wired pressure measurement-based central tire inflation and deflation device is characterized in that a frame is provided with an electromagnetic combination valve box, a pressure sensor, a control valve and an electromagnetic valve combination are arranged in the electromagnetic combination valve box, thus forming a detection air way, an inflation air way and an deflation air way. The wired pressure measurement-based central tire inflation and deflation device has the beneficial effects that a sensor module on a wheel is transplanted in the electromagnetic combination valve box on the frame, the traditional wireless pressure signal transmission mode is optimized into a wired transmission, and the problem of radio frequency interference can be thoroughly solved.
Description
Technical field
The utility model belongs to central vehicle tire deflation system charge control technology, relates to signal transmission and fluid mode.
Background technology
Along with the development of automotive technology, the central vehicle tire deflation system charge uses in increasing vehicle, and this system can improve safety and the crossing ability of vehicle greatly.Traditional central tire air-charging and air-discharging system is at motor tire a pressure detection module (being sensor assembly) to be installed, this inside modules includes pressure sensor and radio frequency chip, can detect in real time tire pressure, and force value is sent out by the receiver module reception of installing on the vehicle frame by wireless radio frequency mode.This product is installed simple, and is easy to use, but weakness is the as easy as rolling off a log radio-frequency (RF) interference that is subject to penetrating, and can make the improper inflation of tire and venting under some certain interference frequency range.
Summary of the invention
The purpose of this utility model provides a kind of wire transmission, avoids the central tire aerating and exhaust device of radio-frequency (RF) interference to remedy the deficiency of prior art.
The utility model for the technical scheme that realizes purpose is: a kind of central tire aerating and exhaust device based on wired pressure measurement, it is characterized in that: be provided with the electromagnetic assembled clack box at vehicle frame, be provided with pressure sensor, control cock and electromagnetic valve combination in the electromagnetic assembled clack box.
Optimize: the inflation gas circuit, namely detect gas circuit, be followed successively by ventilating control valve, tire selector valve, pressure sensor, rotary seal air chamber, wheel limit valve; Be connected with gas exhausting valve by pipeline between ventilating control valve and the tire selector valve.
Optimize: the venting gas circuit is followed successively by between venting control cock, reducing valve, tire selector valve, pressure sensor, rotary seal air chamber, wheel limit valve reducing valve and the tire selector valve and is connected with gas exhausting valve by pipeline.
Optimize, the ventilating control valve of inflation gas circuit and venting gas circuit venting control cock, reducing valve are in parallel.
The beneficial effects of the utility model are: the sensor assembly on the wheel is transplanted in the electromagnetic assembled clack box on the vehicle frame, and traditional pressure signal wireless transmission method is optimized for wire transmission, has thoroughly solved the radio-frequency (RF) interference problem.

The specific embodiment
Embodiment:
The below is described in further details the utility model.
This device is comprised of source of the gas 1, filter 2, electromagnetic assembled clack box 12, rotary seal air chamber 9, wheel limit valve 10 and tire 11.Wherein electromagnetic assembled clack box 12 inside include: venting control cock 3, reducing valve 4, ventilating control valve 5, gas exhausting valve 6, tire selector valve 7 and pressure sensor 8.The notable feature of this device is that pressure sensor 8 has been transplanted to electromagnetic assembled clack box 12 inside.
This device possesses tire pressure and detects three kinds of functions of automatic inflating and automatic deflation.Be lower than and open filling channel under the level threshold value in limited time to tyre inflating when detecting tire pressure; When being higher than upper threshold, opens tire pressure bleed passage to bleeding a tire; Obviously the tire pressure detection is crucial.
Tire pressure measuring ability: open ventilating control valve 5 and tire selector valve 7, high pressure gas are by source of the gas 1 process filter 2, ventilating control valve 5, tire selector valve 7, pressure sensor 8, rotary seal air chamber 9, wheel limit valve 10 flows to tire 11, behind the elapsed time t, close ventilating control valve 5 and tire selector valve 7, pipeline air pressure reaches balance between tire selector valve 7 and the tire 11, the pressure that pressure sensor 8 detects is exactly tire 11 actual pressures, after pressure sensor 8 pressure are read, open blow off valve 6 and tire selector valve 7, gas moment in the pipeline is drained, wheel limit valve 10 cuts out, and tire 11 keeps pressure.
Automatic inflating function: be lower than under the level threshold value in limited time when detecting tire pressure, open charge valve control cock 5 and tire selector valve 7, high pressure gas flow to tire 11 by source of the gas 1 through filter 2, ventilating control valve 5, tire selector valve 7, pressure sensor 8, rotary seal air chamber 9, wheel limit valve 10, to tire 11 inflations.Close ventilating control valve 5 in the time of in tire pressure reaches the level threshold value scope, open gas exhausting valve 6, get rid of the pipeline overbottom pressure wheel limit valve 10 cuts out, tire 11 keeps pressure, reaches the inflation purpose.
Automatic deflation function: be higher than on the level threshold value in limited time when detecting tire pressure, need to open venting control cock 3 and tire selector valve 7, high pressure gas by source of the gas 1 through filter 2, venting control cock 3, reducing valve 4 after step-down be low-pressure gas, low-pressure gas flows to tire 11 through tire selector valve 7, pressure sensor 8, rotary seal air chamber 9, wheel limit valve 10 again, make tire 11 venting, close venting control cock 3 behind the deflation time t2, open ventilating control valve 5 and carry out a tire pressure measuring ability, detect tire pressure and whether reach threshold range.Open blow off valve 6 eliminating pipeline overbottom pressure hour wheel limit valves 10 in the time of in tire pressure reaches threshold range and close, tire keeps pressure.
