Description

Technical Field

[0001] The utility model relates to the technical field of transmission control, and particularly relates to a quantitative control fuel filling system for a transmission. Background Art

[0002] In the transmission component system, the lubrication system plays an important role. At the same time, fuel filling for the transmission needs to be quantitatively filled to ensure that each component is lubricated. At the same time, an appropriate fuel filling amount can reduce various losses, improve efficiency, and reduce material costs, saving costs. If the lubricating oil is insufficient and the oil level is low, key components will be insufficiently lubricated, the pressure cannot be established, and power transmission cannot be carried out, resulting in transmission failures; if there is too much lubricating oil, it will cause excessive heat generation during operation, resulting in too high a transmission oil temperature, affecting the performance of the lubricating oil, excessive additional losses, and reduced transmission efficiency. At the same time, during the operation of the transmission, the oil overflows from the transmission, polluting the environment.

[0003] Therefore, it is particularly important to fill the fuel according to the designed oil level. While meeting the lubrication requirements of the components inside the transmission and the requirements of the hydraulic system stability for the oil volume, the fuel filling amount of the lubricating oil should be reduced as much as possible. This can not only reduce costs but also reduce the stirring power loss of the gears. The reasonable fuel filling amount of the transmission is the first parameter to be confirmed during the test verification stage of the transmission. And it is particularly important to achieve quantitative and fixed-level fuel filling. Summary of the Utility Model
