Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure, 1-wheel box, 2-pressure transducer, 3-data collector, 4-computing machine, 5-display.
Embodiment
For further understanding technology contents of the present utility model, characteristics and effect, enumerate following example now, and conjunction with figs. is described in detail as follows:
With reference to accompanying drawing 1.
Embodiment 1
A kind of construction machinery gear box pressure test device comprises computing machine 4, data collector 3 and pressure transducer 2, and computing machine 4 is equipped with data processing software, and data collector 3 adopts USB interface or serial port data line connected mode with computing machine 4.Data collector 3 even is equipped with 9 pressure transducers 2.Computing machine is provided with display 5, and display 5 can show pressure value and pressure history.
The concrete structure of present embodiment and course of action thereof:
Construction machinery gear box 1 is made up of torque converter and variator and hydraulic control system, its hydraulic control system more complicated, and after breaking down, those skilled in the art and operating personnel are difficult to accurately judge.
Common engineering mechanical gear box 1 retreats fourth gear for the fourth gear of advancing, inside has 6 clutch assemblies, they are respectively to advance and back clutch, 1 grade and 3 grades of clutch couplinges, 3 grades and 4 grades of clutch couplinges, each clutch coupling all has a pressure tap, also have two torque converter imports and top hole pressure in addition, designing altogether on the wheel box hydraulic control system usually has 9 pressure taps.1,2 interfaces are surveyed the torque converter inlet and outlet pressure in the data collector, and the 3-9 interface is surveyed wheel box clutch pressure and hydraulic system pressure, and the interface of this data collector is extendible.
With reference to Fig. 1, this example needs to survey 9 pressure of wheel box, be connected to 9 pressure transducers on the corresponding pressure tap of wheel box by the pressure measurement flexible pipe, data line with sensor connects with the corresponding interface of data collector again, open the power supply of computing machine and data collector, wherein the power supply of data collector can adopt powered battery, has improved the adaptability of data collector like this.After preliminary work finishes, data analysis software in the operation computing machine, starting engine or wheel box drive motor turn round wheel box under the rotating speed of setting, data collector begins to gather the wheel box pressure data and passes to computing machine in real time to be handled, this moment, driver and operating personnel can carry out gear-change operation, can observe simultaneously the pressure history on the computing machine, also can select to preserve data and curve, so that with post analysis.Software can provide the pressure range of general wheel box, for the reason of the trouble location of analyzing wheel box and generation fault.
Computing machine can print pressure curve simultaneously, and the technician is according to the data of test, can analyze the wheel box fault after comparing with empirical data.
