Description

Technical Field

[0001] The utility model relates to the technical field of oil pump testing, and particularly relates to an oil pump testing mechanism for a transfer case. Background Art

[0002] An oil pump is usually installed inside a transfer case. The transfer case is an important part of an automobile and is used to distribute the power of the engine to different wheels to achieve different driving modes. The oil pump inside the transfer case can provide lubricating oil for the transfer case to reduce friction and wear and ensure the normal operation of the transfer case.

[0003] For example, the patent document with the existing patent application number 202221037957.X discloses a transfer case integrated with an oil pump. The oil pump inside the transfer case is usually driven by the engine, and the lubricating oil is transported to each component of the transfer case through an oil pipe. The working principle of the oil pump is similar to that of the engine oil pump. It sucks the lubricating oil into the pump chamber through a rotating impeller and transports the lubricating oil to each component of the transfer case through an oil pipe. After the oil pump in the above solution is assembled, it is necessary to test the oil pump, not only to test whether the sealing performance of the oil pump is good and whether there is a leakage phenomenon, but also to test whether the oil output of the oil pump meets the standard within a certain period of time. Therefore, it is necessary to design an oil pump testing mechanism for a transfer case to facilitate the detection of the assembly quality of the oil pump. Summary of the Utility Model
