Embodiment Construction
[0014] In addition, when compared with the transmission oil temperature measured by the sensor, if the measured value is greater than the set value, it means that the current temperature exceeds the temperature required by our test. At this time, the transmission oil temperature needs to be cooled. , through the action of the circulating oil pump and the internal oil pump of the gearbox, the transmission oil is pumped into the circulation circuit respectively. At this time, under the action of the controller, the cooling unit starts to start, and the stirring device transfers heat evenly to the energy exchange tank. Through the heat exchange between the energy transfer medium in the energy exchange tank and the circulation circuit pipeline, the transmission oil temperature reaches the value set by the controller.
[0015] The invention is not limited to the embodiments discussed above. The above description of specific implementations is intended to describe and illustrate the...

The invention discloses a system for controlling oil temperature of a speed changing box, and a using method thereof. The system comprises a controller, the speed changing box, a temperature sensor, a circulating oil pump, an energy exchange groove, a heating unit and a cooling unit; the controller is used for setting the controlled target oil temperature; and the sensor measures the oil temperature of the speed changing box; an inner oil pump in the speed changing box, an oil inlet and outlet of a cooling pipe and the energy exchange groove form a first circulation loop; and an oil filling port on the speed changing box, an external circulation pump and the energy exchange groove form a second circulation loop. The capacity of testing the performance of the speed changing box quickly at different oil temperatures is achieved.
Description
technical field [0001] The invention relates to a test technology for the performance of auto parts, in particular to a test control system of an auto gearbox at different oil temperatures and a use method thereof. Background technique [0002] The transmission oil temperature has a great influence on the performance and control of the transmission, and it is necessary to test the transmission under different oil temperature conditions during the automobile development process. The traditional laboratory method is to park the car in a low-temperature environment cabin or a high-temperature environment cabin, and gradually realize the change of the transmission oil temperature by changing the temperature of the air in the environment cabin and the heat conduction through the transmission case. However, the disadvantages of the traditional test method are the high energy consumption of the environmental chamber, the long time to achieve the target oil temperature, and the oil ...
