Specific embodiment
Below against attached drawing, by the description of the embodiment, making to a specific embodiment of the invention further details of
Explanation.
As shown in Figure 1, this is used for the Oil-temperature control system of gearbox test-bed, including heat exchanger I 1, heat exchanger
II 2, oil pump 3, gearbox 4, temperature sensor I 5, pressure sensor I 6, temperature sensor II 7, pressure sensor II 8, temperature
Sensor III 9, pressure sensor III 10, flow sensor 11, manual ball valve 12, proportional control valve 13 and controller.
Heat exchanger I 1 and heat exchanger II 2 are heat-exchangers of the plate type, heat exchanger I and heat exchanger II and speed change
Case is arranged side by side, convenient for arrangement.
The primary side of heat exchanger I 1 connects the oil inlet and outlet of gearbox 4, heat exchanger I and gearbox by fluid pressure line
Between connecting line be equipped with temperature sensor and pressure sensor.Further, the oil export of gearbox and heat exchanger I
Between connecting line be equipped with temperature sensor I 5 and pressure sensor I 6, between the oil inlet and heat exchanger I of gearbox
Connecting line on be equipped with temperature sensor II 7 and pressure sensor II 8.One temperature of each installation is distinguished on disengaging oil pipe line
Whether degree, pressure sensor are normal for monitoring gearbox disengaging oil circulation.
The secondary end of heat exchanger I 1 is connected with the secondary end of heat exchanger II 2, and oil pump is located at heat exchanger I and heat exchange
On the pipeline of device II between the two, the connecting line between heat exchanger I and heat exchanger II is equipped with III 9 He of temperature sensor
Pressure sensor III 10；Connecting line between heat exchanger I and heat exchanger II is equipped with the hand for filling gear box oil
Dynamic valve, hand-operated valve are manual ball valve 12.The outlet end setting of temperature sensor III and the corresponding oil pump of pressure sensor III.
The oil pump that a controllable rotating speed is installed on fluid pressure line between heat exchanger I and heat exchanger II, passes through control
The revolving speed of liquefaction pump adjusts the flow of hydraulic oil in the pipeline.One is installed manually by three-way connection in the input end of oil pump
Ball valve opens the hand-operated valve, can be into the pipeline and the secondary end of heat exchanger I and heat exchanger II fills fluid drive
Case oil；It is also equipped with a temperature and pressure sensor in the outlet end of oil pump simultaneously, is for monitoring oil circulation in the pipeline
It is no normal.
The primary side of heat exchanger II and the gearbox outer loop water phase of test-bed connect, and set on circulating water pipe road
Proportional control valve 13 and flow sensor 11.One ratio adjusting valve and flow sensing are installed in the input end of heat exchanger II
Device, for adjusting the cooling water flow for entering heat-exchangers of the plate type II.
All temperature, pressure and flow sensors are connected with controller, proportional control valve and oil pump also with control
Device processed is connected, and realizes the automatic control of automatic gear-box oil temperature.
The cooling water of testboard bay and the gear box oil of II secondary end of heat-exchangers of the plate type carry out heat exchange, board-like heat exchange
II secondary end and I secondary end of heat-exchangers of the plate type pass through oil pump progress forced circulation, the change of last I secondary end of heat-exchangers of the plate type
Fast case oil carries out heat exchange with the gear box oil of I primary side of heat-exchangers of the plate type again.It is real in this way by way of twin-stage heat exchange
Gear box oil-gear box oil heat transfer process between cooling water-heat exchanger is showed.

PID arithmetic inside device RTU carries out feedback closed loop control, adjusts the revolving speed of oil pump and the aperture of proportioning valve in real time, so i.e.
Realize the automatic control of automatic gear-box oil temperature.When automatic transmission fluid temperature at outlet is greater than set temperature, increase
The cooling capacity of the aperture of proportioning valve, heat-exchangers of the plate type II increases, and the gear box oil temperature between heat exchanger reduces；Oil pump turns
Speed becomes faster, and the automatic transmission fluid between heat exchanger, which recycles, to be accelerated, and the cooling capacity of heat-exchangers of the plate type I increases, and is tested speed change
Case oil temperature reduces.When automatic transmission fluid temperature at outlet is less than set temperature, reduce the aperture of proportioning valve, board-like heat exchange
The cooling capacity of device II reduces, and the gear box oil temperature between heat exchanger increases；Pump speed reduces, automatic between heat exchanger
Gear box oil circulation slows down, and the cooling capacity of heat-exchangers of the plate type I reduces, and being tested TOT Transmission Oil Temperature reduces.
Meanwhile controller RTU also will real time monitoring gearbox disengaging oil temperature, pressure and oil pump out of the mouth temperature pressure
Power, to judge whether gearbox and operation of oil pump are normal.Using the outer circulation twin-stage type of cooling to automatic transmission fluid into
Row cooling, is able to achieve the automatic control of automatic gear-box oil temperature, and Oil-temperature control range is wider；Substantially increase gearbox
The control precision of oil temperature, comprehensive temperature, pressure monitoring, greatly improves the stability and the degree of automation of equipment.
The use of twin-stage heat-exchangers of the plate type, even if slightly leaking occurs in heat-exchangers of the plate type I, gearbox oil liquid will not
It is mixed into cooling water, greatly reduces the risk of test；It is easy to be transformed, the primary cooling water of heat-exchangers of the plate type II is become into heat
Water can be realized and heat to gear box oil, even if gear box oil can also maintain a stable temperature in low-load situation
It spends in range.
It above are only and preferred embodiments of the present invention are illustrated, above-mentioned technical characteristic can form multiple hairs in any combination
Bright example scheme.
The present invention is exemplarily described above in conjunction with attached drawing, it is clear that the present invention implements not by aforesaid way
Limitation, if use the improvement for the various unsubstantialities that conception and technical scheme of the invention carry out, or it is not improved will
Conception and technical scheme of the invention directly apply to other occasions, within the scope of the present invention.
