Technical field
The present invention relates to a kind of leakage amount measuring device for electricity, particularly relate to a kind of automatic transmission application valve body from leakage amount measuring device for electricity.
Background technology
At present, application valve body is a kind of hydraulic control that is widely used in automatic transmission inside, is the core of automatic speed variator hydraulic system, and major function is to carry out the gear shift action to topworks's pressure oil output such as clutch couplinges.Application valve body is as a hydraulic system, it from leakage rate, be a key index.Knownly to application valve body, from the measuring method of leakage rate, generally take below application valve body placing container to collect the mode of leakage fluid force feed, this method does not have real-time, and the wall cling phenomenon of hydraulic oil also can have a strong impact on the accuracy of measurement.Therefore need a kind of measurement mechanism of real-time and accurately application valve body being measured from leakage rate.
Summary of the invention
The object of the invention is to overcome the weak point existed in above-mentioned technology, provide a kind of simple in structure, reasonable in design, precision is high, long service life, easy accessibility, safe and reliable, can measure real-time and accurately application valve body from the automatic transmission application valve body of leakage rate from leakage amount measuring device for electricity.
In order to achieve the above object, the technical solution used in the present invention is: comprise application valve body, described application valve body is fixedly mounted on the test tool jig, with valve body gear controller, tensimeter, be connected, the oil-in of application valve body is communicated with oil groove by outside in-line, the draining end of application valve body is communicated with oil groove by outside drain line, also is provided with successively pressure flow hybrid control unit, inlet flow rate meter on described outside in-line, also is provided with the rate of discharge meter on outside drain line.
Advantage of the present invention is:
1, simple in structure, reasonable in design, manufacture difficulty is low;
2, maintenance cost is low, and failure rate is low is measured accurately highly versatile;
3, the measuring principle of measurement mechanism is correct, measures quickness and high efficiency, can show fully and effectively that application valve body is from leakage rate.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, embodiments of the invention are described in further detail.
As shown in Figure 1, the present invention includes application valve body 7, described application valve body 7 is fixedly mounted on test tool jig 6, with valve body gear controller 5, tensimeter 8, be connected, the oil-in 12 of application valve body 7 is communicated with oil groove 1 by outside in-line 2, the draining end 11 of application valve body 7 is communicated with oil groove 1 by outside drain line 9, and on described outside in-line, 2 also are provided with pressure flow hybrid control unit 3, inlet flow rate meter 4 successively, on outside drain line 9, also are provided with rate of discharge meter 10.
The present invention is arranged on test tool jig 6 at application valve body 7, the oil-in 12 of application valve body 7 by test tool jig 6 with outside in-line 2, be connected, drain tap 11 passes through test tool jig 6 and is connected with outside drain line 9, add the oil circulation of a simple oil suction-oil return of oil groove 1 formation, wherein application valve body 7 also can drip 1 li of oil feed groove naturally from leakage flow.Fuel feeding one side on application valve body 7 left sides, hydraulic oil passes through pressure flow hybrid control unit 3 adjust fluxes and pressure, and, through inlet flow rate meter 4 measuring flows, feeds application valve body 7.Application valve body 7 is controlled by valve body gear controller 5 and is carried out gear, and the operating oil pressure of generation is measured by tensimeter 8, and valve body draining flow is discharged through outside drain line 9.What application valve body 7 produced simultaneously can flow out from leakage rate, drips oil-recovery tank 1, and the hydraulic oil of leakage is as shown in the oil droplet under application valve body in Fig. 17.Fuel feeding one side on application valve body 7 the right, the draining flow of application valve body 7, by outside drain line 9 guiding, after rate of discharge meter 10 measuring flows, flows back to oil groove 1.From the Flow continuity equation, inlet flow rate meter 4 results should be for valve body from leakage flow and valve body draining flow sum, so the measurement result that the measurement result of inlet flow rate meter 4 deducts rate of discharge meter 10 is the flow value of valve body from leakage flow.
Principle of the present invention is: the hydraulic oil in oil groove 1 is under the effect of pressure flow hybrid control unit 3, flow to inlet flow rate meter 4 by outside in-line 2, after by inlet flow rate meter 4 measuring flows, the test tool jig 6 of flowing through enters the oil-in 12 of application valve body 7.Hydraulic oil is in application valve body 7 inside, and valve body, as the pressure oil that maintains gear, is not flowed out in first, and its working pressure is recorded by tensimeter 8; Second portion, as the draining flow, flows out by outside drain line 9; Third part be valve body from leakage flow, in surface or the gap of application valve body 7, overflow, drip oil-recovery tank 1.Now the duty of valve body is that gear is controlled by valve body gear controller 5.After the draining traffic flow inlet/outlet flowmeter 10 measured flows that flowed out by outside drain line 9, backflow oil feed groove 1.Known according to the Flow continuity equation, the measurement result that valve body is inlet flow rate meter 4 from the actual flow value of leakage flow and the result of rate of discharge meter 10 poor.
Control the work gear switch of application valve body 7 by valve body gear controller 5, can obtain valve body under different gears from the leakage rate characteristic; By adjusting the fuel feeding oil pressure of pressure flow hybrid control unit 3, can obtain that under different operating pressure, valve body is from the leakage rate characteristic, working pressure shows by tensimeter 8; By changing the hydraulic oil of oil groove 1 interior different temperatures, can obtain valve body under different oil temperatures from the leakage rate characteristic, form thus and a set ofly improve comprehensive automatic transmission application valve body from the leakage rate measuring method
The present invention is based on the Flow continuity equation, make poor method by the gateway flowmeter and realized the real-time measurement from leakage flow to valve body, reliability and the accuracy of test findings have effectively been improved, for the design optimization of automatic transmission application valve body provides strong test figure support.
