Description
Technical field
The utility model relates to the detection technique field of engineering truck variator valve body, is specifically related to a kind of vehicular transmission application valve body pick-up unit.
Background technology
In the variator of engineering truck, in valve body, the break-make of oil circuit is the key that can Hydrodynamic transmission normally work.If stopping up or fault appears in oil circuit, will directly affect the transmission performance of car load, even there is the stuck problem such as flame-out.Existing such Hydrodynamic transmission valve body proving installation generally adopts primary instrument directly to measure, and can only manually operate valve body testing procedure, will repeatedly shift gears test to certain valve body especially time, more need manually to operate, operator should Monitoring Data, operation gearshift again, workload is very large.In addition, the working electromagnet valve in valve body is more, and is installed on valve inner, when fault, cannot judge defect or the solenoid valve failure of oil circuit, only have the test by repeatedly just can complete single sleeve valve body to valve body dismounting inspection, hand labor intensity further raises, and work efficiency is lower.
Utility model content
The purpose of this utility model is: provide a kind of vehicular transmission application valve body pick-up unit, solving the existing complicated operation of traditional detection device, hand labor intensity is large, precision is low and affect the problem of work efficiency.
The purpose of this utility model is achieved by the following technical solution:
A kind of vehicular transmission application valve body pick-up unit, comprise total power switch, Universal Switching Power Supply, controller and the shunt of series connection successively, on controller, be connected with respectively monitoring modular and pressure transducer, on controller, be also connected with test start-stop button, described total power switch and shunt are provided with external interface.
Described total power switch is connected with 220V alternating current, and shunt detects solenoid valve with need and is connected.
Described monitoring modular is provided with alarm lamp.
Described shunt has 10 and specification to be 2A, 200mV.
The range of described pressure transducer is 4Mpa, output 0-5V signal.
Described pressure transducer has 6.
The beneficial effects of the utility model are:
Compared with prior art, the vehicular transmission application valve body pick-up unit that the utility model provides has the following advantages:
1, the equal real-time inspection and control of output input signal of proving installation, can understand the failure cause in process of the test in time, helps operating personnel to complete sooner analytic process;
2, install concentratedly, operation, demonstration, monitoring integration, improved operability and the practicality of test process;
3, versatility is high, can adapt to dissimilar valve body test request.
Brief description of the drawings
Fig. 1 is system chart of the present utility model;
In figure: 1-controller, 2-Universal Switching Power Supply, 3-pressure transducer, 4-shunt, 5-monitoring modular, 6-alarm lamp, 7-tests start-stop button, 8-total power switch.
Embodiment
Below in conjunction with drawings and Examples, the technical solution of the utility model is described further, but described in desired protection domain is not limited to;
As shown in Figure 1, the vehicular transmission application valve body pick-up unit that the utility model provides, it comprises total power switch 8, Universal Switching Power Supply 2, controller 1 and the shunt 4 of connecting successively, on controller 1, be connected with respectively monitoring modular 5 and pressure transducer 3, on controller 1, be also connected with test start-stop button 7, total power switch 8 and shunt 4 are provided with external interface.
Described total power switch 8 is connected with 220V alternating current, and shunt 4 detects solenoid valve with need and is connected; 220V alternating current is driving power, and the solenoid valve that drives this device to detect need detects.
In order to show fast the state of monitoring modular 5, described monitoring modular 5 is provided with alarm lamp 6.
Described shunt 4 has 10 and specification to be 2A, 200mV, and its tracking that can simultaneously complete 10 solenoid valves detects, and has effectively improved detection efficiency.
In order to ensure accuracy of detection and to be controlled to pump, the range of described pressure transducer 3 is 4Mpa, output 0-5V signal.
In order to be convenient to monitor the oil pressure value of valve body, described pressure transducer 3 has 6.
Embodiment: when use, thereby 220V interchange is accessed in Universal Switching Power Supply 2 and made 220V alternating current change 24V direct current into for whole proving installation power supply by total power switch 8; Export at controller 1 between the signal wire of each solenoid valve and connect respectively shunt 4, the specification of shunt 4 adopts 2A, 200mV, totally ten of quantity, and controller 1 is monitored the current value of electromagnetic valve work by measuring shunt 4 magnitudes of voltage.The output signal of pressure transducer 3 is connected in controller 1, and it is 4Mpa that the specification of pressure transducer 3 adopts range, is output as 0-5V signal, and totally six of pressure transducer 3 quantity are monitored the oil pressure value of valve body by gaging pressure sensor 3 magnitudes of voltage.In the time carrying out valve body test, press successively total power switch 2 and test start-stop button 7, proving installation just can carry out the work of valve body gearshift loop test repeatedly, if will stop test, again presses test start-stop button 7.
The valve body Motion control algolithm executive routine of controller 1 is pressed N gear successively, 1 gear, 2 gears, 3 gears, 4 gears, 5 gears, 6 gears, 5 gears, 4 gears, 3 gears, 2 gears, 1 gear, N gear; R keeps off N gear to carry out after the work of solenoid valve logical combination, then carries out above-mentioned gearshift circulation, and the duration of each gear is 6s.In the time that controller 1 finds that oil pressure numerical value in monitoring modular 5, current values are undesired, can tell operating personnel to answer checkout failure cause by alarm lamp 6.If electromagnetic valve current numerical value lower than setting value, can judge that electric control part is divided and break down, when oil pressure numerical value is lower than setting value, may be electric signal fault, may be also Hydraulic Elements occur that clamping stagnation or valve body exist leakage failure.
Through after 100 loop tests repeatedly, the sustainable rising of working oil temperature of valve body, now fluid is thinning, is very easy to find whether defectiveness of valve body blank.
