Description of drawings
Below in conjunction with the drawings and specific embodiments the technical solution of the utility model is further described in detail.
Fig. 1 is the agent structure schematic diagram of hydraulic automatic speed variator testing table of the present utility model.
Fig. 2 is the structural drawing of oil temperature automatic control system.
Embodiment
As shown in Figure 1, the kernel subsystems of experiment control system and working-condition monitoring system is integrated in the illustrated industrial computer control system, instrument system belongs to the peripheral subsystem of working-condition monitoring system, and experiment control system is communicated by letter in the industrial computer control system with the working-condition monitoring system kernel subsystems.Input-driven system is comprised of drive motor, frequency converter, sensor and shaft coupling, illustrated " drive motor frequency converter " square frame represents the main body regulation and control parts of input-driven system, and " moment instrument " square frame has represented the sensor units such as many driving rotating speeds, moment.The main body regulation and control parts of input-driven system, sensor unit, variator ECU (Electrical Control Unit), oil temperature automatic control system, hydraulic oil automatic filling/drainage system, instrument system are respectively by CAN bus and the communication connection of industrial computer control system.
The oil temperature automatic control system comprises oil temperature heating arrangement, heating controller and oil temperature sensor.Hydraulic oil automatic filling/drainage system comprises fuel reserve tank, oil filling/drainage device, and one section of the oil temperature heating arrangement is positioned at fuel reserve tank, and the other end connects heating controller, and heating controller connects described experiment control system.The I/O end of oil temperature filling/drainage device connects tested hydraulic automatic speed variator, and the control end of oil temperature filling/drainage device connects described experiment control system.Oil temperature sensor connects working-condition monitoring system.
According to the hydraulic automatic speed variator characteristic, transmission oil need to reach approximately 80 ℃ design temperature in the process of the test, is higher than environment temperature far away.Traditional mode of operation is before test, adds the hydraulic oil under the environment temperature, by opening variator work, by the slow effect that heats up of self physical construction drive hydraulic working oil realization.And in the utility model owing to having adopted the oil temperature automatic control system, can judge current oil temperature according to the host computer working-condition monitoring system before the test, whether to need to be determined transmission oil is heated or lowered the temperature operation by experiment control system, heat up if need, then system program control is opened the oil temperature control system automatically to the transmission oil control that heats up, after reaching design temperature, change hydraulic oil automatic filling system works over to, will reach the hydraulic oil of design temperature according to setting the consumption automatic filling to variator.
Oil temperature automatic control system and tested hydraulic automatic speed variator consist of circulating oil path.In process of the test, keep the oil temperature automatic control system to be in all the time opening.When sensor detection oil temperature was lower than the design temperature scope, system opened heating arrangement automatically, hydraulic oil is flow to be back to variator inside after heat at oil temperature automatic control system place; When oil temperature is higher than the design temperature scope, close heating arrangement, open heat abstractor, by the oil temperature automatic control system hydraulic oil is carried out radiating and cooling, regulate in real time gearbox oil temperature and be in the normal working temperature scope.
Fig. 2 has provided a kind of embodiment of oil temperature automatic control system, when temperature sensor 2 detection oil temperatures are lower than the design temperature scope, and the oily heat temperature raising that heating arrangement 1 is given in the fuel reserve tank 7.After arriving design temperature, oil filling/drainage device injects oil in the variator 10 by the first filtrator 4, flow sensor 3, retaining valve 5.After test was finished, the oil in the variator 10 arrived in the fuel reserve tank 7 by its drain pan drain tap, 6 extractions of the second filtrator.If the oil temperature in the variator 10 is too high, then start cool-heat-exchanger, through the 3rd filtrator 8, to the oily circulation cooling cooling in the variator 10.
Because there is the intrinsic phenomenon of neutral gear band row rotating speed in hydraulic automatic speed variator, just allows to start to walk engage a gear (switching to 1 grade or reverse gear from neutral gear) and only have in the variator fluid drive strategy when output shaft is almost static.On test-bed, because output shaft is unloaded, therefore because band row phenomenon has caused the output shaft rotating speed higher, directly have influence on the variator engage a gear of can't starting to walk.The output brake system is used for fictitious load, comprises Brake Block and brake monitor, brake monitor and experiment control system communication connection, and tested hydraulic automatic speed variator OSS connects working-condition monitoring system.When the operation of needs variator starting engage a gear, by experiment control system the output brake system work of opening is set, restriction output shaft rotating speed raises.Behind starting engage a gear EO, judge that by experiment control system automatically will export brake system unclamps, and does not affect follow-up test project gear-change operation.
In order to prevent fault to the safety of testing table, testing table is set with the many places emergency stop function, except " suddenly stopping " button is installed at testing table hardware operation platform, has also set various emergency stop action panes on the experiment control system control desk.During practical application, select different scram buttons according to the field failure urgency level respectively.Selecting the first emergency stop push button is that " disable motor " reduces to zero with the input-driven system motor speed; Also can select the second emergency stop push button, only close tested hydraulic automatic speed variator ECU (Electrical Control Unit); Can also select the 3rd emergency stop push button " to stop in emergency ", a whole set of stand arrangement running of emergent stopping.
It should be noted last that, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although with reference to preferred embodiment the utility model is had been described in detail, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
