Description

Technical Field

[0001] This invention relates to the field of lubricating oil monitoring, and more specifically to a lubricating oil quality monitoring system for vehicle axles with active filtration. Background Technology

[0002] When a vehicle is in motion, the friction between the tires and the road surface generates heat and energy loss. To reduce this friction and heat loss, axles use lubricating oil to lubricate the wheels and bearings, reducing friction and improving fuel efficiency.

[0003] Using the right lubricating oil ensures proper vehicle operation and extends vehicle life. Regularly changing the lubricating oil is also a preventative maintenance measure, helping to identify and resolve potential vehicle malfunctions, such as the accumulation of waste deposits, metal particles, and other residues.

[0004] Current axle lubricant monitoring systems are typically passive, requiring periodic replacement of clamp samples for analysis. This monitoring method is not ideal because it cannot monitor impurities and contaminants in the axle lubricant in real time, ultimately making it difficult to ensure the normal operation of machinery and equipment and to take necessary maintenance measures in a timely manner. Summary of the Invention

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] Please see Figures 1-3 As shown, the present invention is a lubricating oil quality monitoring system for vehicle axles with active filtration, comprising:

[0044] The sampling module is used to acquire the impurity content, which reflects the quality of the lubricating oil, in real time.

[0045] The first analysis module is used to score the lubricating oil based on the impurity content to obtain an oil quality evaluation value, and can detect the quality of the lubricating oil.

[0046] The active filtration module is used to execute corresponding active filtration strategies based on oil quality evaluation values, thereby filtering impurities inside the lubricating oil.

[0047] The second analysis module is used to obtain an active filtration effect score based on the impurity content after the active filtration strategy is implemented, thereby judging the oil quality and filtration effect after active filtration.

[0048] The early warning module is used to process the active filtration module according to the active filtration effect score, so as to ensure that the filter screen 7 filters the lubricating oil normally.

[0049] Methods for obtaining oil quality evaluation values ​​include:

[0050]

[0051] S1 represents the impurity content of the lubricating oil before it enters the active filtration module; Z represents the preset lubricating oil standard value; and F represents the oil quality evaluation score, which can determine the quality of the lubricating oil.

[0052] The specific structure and active filtering strategy of the active filtering module include:

[0053] The specific structure of the active filtering module includes an oil pipe 1 and a limit housing 2. The limit housing 2 is fixedly installed on the outer surface of the oil pipe 1. Inside the limit housing 2, a first micro-cylinder 3 is evenly and fixedly installed. The top of the first micro-cylinder 3 is fixedly connected to a filter screen plate 7. Inside the limit housing 2 and on one side of the filter screen plate 7, a cleaning plate 6 is slidably clamped. At the center of the top of the cleaning plate 6, a limit rod 5 is fixedly connected. At both ends of the top of the cleaning plate 6, slag discharge pipes 4 are fixedly connected. The top of the limit rod 5 is fixedly connected to a second micro-cylinder. At the bottom end of the cleaning plate 6, a slag suction nozzle 9 is provided;

[0054] The active filtering strategy includes:

[0055] When F < a, it indicates that the evaluation value score of the oil product is within the normal range, so the active filtering module does not need to be started.

[0056] When F > b, it indicates that the evaluation value score of the oil product is outside the normal range, and the active filtering module needs to be started to make the three groups of filter screen plates 7 operate.

[0057] When a < F < b, it indicates that the quality of the oil product starts to decline, so the active filtering module needs to be started to make the two groups of filter screen plates 7 operate;

[0058] Among them, a and b are respectively the critical range values of F.

[0059] The method for obtaining the active filtering effect score includes:

[0060] The formula for the active filtering effect score:

[0061] When P > 1, it indicates that the evaluation value of the oil product before the active filtering module is greater than the evaluation value of the oil product after the active filtering module, so the filtering effect is not good;

[0062] When P < 1, it indicates that the evaluation value of the oil product before the active filtering module is less than the evaluation value of the oil product after the active filtering module, achieving effective filtering;

[0063] Among them, F is the evaluation value of the oil product before starting the active filtering module, and F1 is the evaluation value of the oil product after starting the active filtering module.

[0064] The specific structure of the warning module includes an alarm unit, and the alarm unit includes a warning light. The warning light can warn the driver that the filtering effect of the active filtering module is not good and the side of the filter screen plate 7 needs to be cleaned;

[0065] If P > Y1 > 1, it indicates that the side of the filter screen plate 7 is blocked, and the cleaning plate 6 is started to descend to clean the blockage on the side of the filter screen plate 7;

[0066] If P < Y1 < 1, it indicates that the flow on the side of the filter screen plate 7 is normal, and no adjustment is made.

[0067] Y1 is a preset standard threshold. During the early warning process, the active filtration effect score P is compared with the preset standard threshold Y1 to determine whether the filtration effect of the filter screen 7 is normal.

[0068] The sampling module includes a micro-pump and a detector. Oil troughs 8 are evenly distributed at the bottom of the oil pipe 1. The micro-pump and detector are installed inside the oil troughs 8. The micro-pump is used to extract lubricating oil from inside the oil troughs 8. The oil troughs 8 are distributed on both sides of the filter screen 7, allowing for the detection of the lubricating oil filtered by the filter screen 7. This determines the filtration effect of the filter screen 7 on impurities in the lubricating oil. The micro-pump can be controlled to extract lubricating oil from inside the oil troughs 8, facilitating the detector's detection of the extracted lubricating oil and obtaining oil parameter data. The parameter data is then compared to determine the current impurity content of the lubricating oil. A micro-oil pump is fixedly connected to the top of the oil residue conduit 4, facilitating the absorption of impurities scraped from the sides of the filter screen 7, ensuring the filtration effect of the filter screen 7.

[0069] The early warning module is used to monitor the filtration efficiency of the filter plate, determine whether the filter plate can filter the lubricating oil normally, and at the same time, it can warn that there is a lot of blockage on the side of the filter screen plate 7. It can also activate the cleaning plate 6 to drive the scraper 10 to scrape and clean the blockage on the side of the filter screen plate 7, so as to ensure the normal filtration effect of the filter screen plate 7 on the lubricating oil. The scraper 10 is located on the side of the cleaning plate 6 above the suction nozzle 9, and the suction nozzle 9 and the scraper 10 are not in the same vertical direction, so that the suction nozzle 9 can easily remove the blockage scraped by the scraper 10.

[0070] By dividing the filter plates into three groups to perform multi-stage filtration of the lubricating oil, impurities can be filtered out on the side of the filter screen 7, thereby reducing the flow of impurities in the lubricating oil and reducing the wear caused by impurities on the internal parts of the axle. At the same time, the detector can be controlled to monitor the impurity content after filtration by the three groups of filter plates, and the three sets of data can be compared to determine whether the quality of the lubricating oil meets the standard value.

[0071] Working principle of the present invention: The acquisition module first controls the micro pump to extract the lubricating oil before the first group of filter plates 7 inside the axle, facilitating the detector to detect the collected lubricating oil to obtain the initial impurity content S1 of the detection. Then, the ratio of the impurity content S1 to the preset lubricating oil standard value Z is used to obtain the oil quality evaluation value F. Therefore, when F < a, the active filtration module does not need to be started. When F > b, the active filtration module needs to be started to make the three groups of filter plates 7 operate. When a < F < b, the active filtration module needs to be started to make the two groups of filter plates 7 operate. Among them, when the active filtration module operates, it will control the first micro cylinder 3 to drive the filter plate 7 connected to one end to descend, so that the filter plate 7 filters the lubricating oil in the oil circuit, preventing impurities from flowing with the lubricating oil in a cycle and affecting the normal operation of the axle. Then, the acquisition module is started again to detect the lubricating oil after active filtration to obtain the second oil quality evaluation value F1. Then, the ratio of the oil quality evaluation value F obtained for the first time to the second oil quality evaluation value F1 is used to obtain the active filtration effect P. Therefore, when P > 1, it means that the filtration effect is not good. When P < 1, it means that the active filtration module can filter impurities normally. Then, after the active filtration module has been used for a long time, if P > Y1 > 1, the warning module will be started, and then the cleaning plate 6 will be started to descend to clean the blockage on the side of the filter plate 7. If P < Y1 < 1, no adjustment will be made. When cleaning the blockage on the side of the filter plate 7, first start the second micro cylinder to drive the cleaning plate 6 connected to one end to descend along the side of the filter plate 7 through the limiting rod 5. At the same time, the cleaning plate 6 will push the scraping plate 10 to scrape the impurities on the side of the filter plate 7, and at the same time start the micro oil pump to extract the scraped impurities through the slag suction nozzle 9, so as to dredge the side of the filter plate 7 until the second micro cylinder drives the cleaning plate 6 to rise and reset. Then, start the active filtration module again to detect the lubricating oil filtered by the filter plate 7, and compare the oil quality evaluation value F before and after and the second oil quality evaluation value F1 again. If P < 1, it means that the blockage on the side of the filter plate 7 can be removed. Therefore, the monitoring impurity content of the lubricating oil is obtained through the acquisition module, and the oil quality evaluation value F of the oil product and the active filtration effect score P are obtained, so as to evaluate the oil quality of the lubricating oil inside the axle, and the impurities and pollutants inside the lubricating oil can be actively filtered to ensure the quality of the lubricating oil inside the axle.

[0072] The above has described an embodiment of the present invention in detail, but the content is only the preferred embodiment of the present invention and cannot be considered as limiting the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
