The transmission am oil temperature has a great impact on the performance and control of the transmission. In the process of automobile development, it is necessary to test the transmission under different oil temperatures. The traditional laboratory method is to park the vehicle in a low-temperature environment chamber or a high-temperature environment chamber, and gradually change the transmission oil temperature by changing the air temperature in the environment chamber and heat conduction through the transmission housing. However, the disadvantages of the traditional test method are high energy consumption in the environmental chamber, long time to achieve the target oil temperature, and the oil temperature cannot be stable during the test / vehicle operation.

The transmission am oil temperature control system needs to meet the requirements of quickly testing the transmission performance under different oil temperature environments, achieve the target oil temperature and keep the oil temperature constant at the target value, and keep the oil volume inside the transmission unchanged during the testing process; During the circulation and heat transfer of the transmission oil, bubbles shall be prevented and the oil shall not be damaged due to local overheating technical requirements for transmission am oil temperature control system.

1. The dynamo meter control system can control the oil temperature of the test piece;

2. The control system can monitor and control the oil temperature at the inlet / outlet of the oil circulation system;

3. Two PT100 temperature sensor interfaces are reserved. The temperature control system can collect the signal and control the circulating oil flow or cooling rate according to the signal;

4. The built-in heater can heat the circulating oil, and the heating rate is -20 ℃ -85 ℃, within 30min;

5 Add a thermostatic control valve to control the flow of external circulating water to ensure that the temperature of the test piece is constant or constant in a small range;

6. Oil circulating system includes oil filter to protect oil pump;

7. Add a filter to prevent damage to the oil pump caused by large particle chipping;

8. Adopt the form of motor + mechanical gear pump;

9. It has automatic temperature control function, automatic alarm function for oil shortage, etc.

The transmission am oil temperature control system can save a lot of energy due to the small control medium mass and target oil volume, and the time to achieve the target oil temperature is short. At the same time, it can ensure that the oil temperature remains stable during the test or vehicle operation, and greatly improve the work efficiency due to the system control.
