Description

technical field [0001] The invention relates to the technical field of transmission lubrication, in particular to a system and a testing method for testing the amount of lubricating oil in a transmission and the ventilation. Background technique [0002] The amount of lubricating oil in an automobile transmission is a crucial factor for the overall performance of the transmission. The amount of lubricating oil directly affects the gear lubrication effect, oil temperature stability, assembly transmission efficiency and internal structure life of the transmission. Therefore, it is extremely important to test and evaluate the transmission lubricating oil quantity accurately and efficiently. Usually, the transmission lubricating oil quantity test needs to carry out multiple sets of complex tests with different oil quantities and different working conditions. However, there are some problems of low efficiency and low precision in the transmission lubricating oil quantity test pro...

Problems solved by technology

Usually, the transmission lubricating oil quantity test needs to carry out multiple sets of complex tests with different oil quantities and different working conditions. However, there are some problems of low efficiency and low precision in the transmission lubricating oil quantity test process: (1) During the lubricating oil quantity test process , needs to go through multiple filling / draining of oil. At present, most of them use measuring cups and funnels for filling. There is a small amount of lubricating oil hanging on the funnel and measuring cups every time they are filled. After multiple rounds of filling, the accuracy of the amount of oil It will be greatly reduced, and the efficiency will be low while affecting the test results; (2) When detecting whether the vent plug is leaking oil, the test personnel need to be close to the high-speed rotating test bench to observe, and it is dangerous to find the oil leak situation and give an alarm; (3) The oil temperature in the detection record is discontinuous, there is no over-temperature alarm, and each link is independent and discontinuous, which is not conducive to the subsequent processing and analysis of the test results by the test personnel
