AI Technical Summary
Existing transmission oil supply systems are prone to air intake at low temperatures, leading to cavitation problems, and at high temperatures, they cause splashing losses. Furthermore, the structural limitations of hybrid transmissions result in insufficient storage space in the storage container, making it difficult to achieve stable control of the fluid level.
A valve device is used between the volume compensation container and the storage container. An expansion element automatically adjusts the hydraulic connection according to temperature changes to ensure stable liquid level. The expansion element, such as wax or metal alloy, adjusts the flow cross section by temperature changes to prevent air intake and splashing.
The system automatically adjusts the liquid level at different temperatures to avoid air intake and splashing losses, thereby achieving stable operation and efficient transmission of the gearbox and saving structural space.
