[0013] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0014] like Figure 1 As shown, the utility model provides a replenishing system for insufficient lubricating oil in a gearbox 10, wherein a driving wheel 11 is arranged in the gearbox 10 and contains lubricating oil, and the lower end of the driving wheel 11 is immersed in the lubricating oil so as to drive the lubricating oil to splash and lubricate when the driving wheel 11 rotates; the utility model comprises a sensor 20, an oil reservoir 30, an oil pump, and a controller 40; the sensor 20 is arranged on the gearbox 10, and the sensor 20 comprises a Hall sensor 21, a tilt sensor 22, a temperature sensor 23, a resistance level sensor 24, and an absolute pressure sensor 25 so as to monitor the gearbox 10; the oil reservoir 30 is connected to the gearbox 10 by a pipeline, and the oil reservoir 30 also contains lubricating oil; the oil pump is arranged between the gearbox 10 and the oil reservoir 30, so as to pump the lubricating oil in the oil reservoir 30 into the gearbox 10; the controller 40 is respectively connected to the sensor 20 and the oil pump in communication, so as to receive the signal of the sensor 20 and to control the opening and closing of the oil pump; the oil pump is a prior art and will not be described in detail here.

[0015] Furthermore, one Hall sensor 21 is provided for monitoring the rotation speed of the driving wheel 11, two tilt sensors 22 are provided, and the two tilt sensors 22 are respectively used to monitor the roll angle of the gearbox 10 and the overhead angle of the gearbox 10, one temperature sensor 23 is provided for monitoring the internal temperature of the gearbox 10, one resistance liquid level sensor 24 is provided for monitoring the oil height, and one absolute pressure sensor 25 is provided for monitoring the internal air pressure of the gearbox 10.

[0016] Furthermore, the gearbox 10 also includes a driven wheel 12. Both the driving wheel 11 and the driven wheel 12 are gears that mesh with each other. The driving wheel 11 and the driven wheel 12 are used to drive the lubricating oil to splash when rotating.

[0017] Furthermore, a speaker is included, and the speaker is communicatively connected to the controller 40 to generate sound to remind the user.

[0018] Specifically, the controller 40 contains a lubrication simulation analysis module, an intelligent training module and an early warning decision module. By acquiring, processing and transmitting the signals collected by the sensor, the real-time working condition of the splash lubrication of the gearbox 10 is monitored and captured. After the signal is processed into corresponding data, it is transmitted to the lubrication simulation analysis module as working condition data, and splash lubrication simulation analysis is performed on the corresponding working condition. The lubricating oil liquid volume fraction and lubricating oil amount of important parts such as the bearing area and the gear meshing area in the analysis results are extracted as lubrication effect evaluation data, and the working condition data and the lubrication effect evaluation data are merged into a multi-working condition simulation data set (the amount of data can be appropriately increased or decreased according to the computing power of the computer, and a representative working condition can be selected to constitute the data set) and transmitted to the intelligent training module. After learning and training the machine learning model of the module, the lubrication effect evaluation index of the real-time splash lubrication working condition collected by the sensor 20 can be predicted, and the prediction data of the corresponding working condition (the oil liquid volume fraction and the lubricating oil amount of the key parts) is output. The predicted data is transmitted to the early warning decision module, compared and judged with the set threshold value, and the predicted data less than the threshold value is warned by the early warning decision module, and a warning sound is issued through the speaker;

[0019] Specifically, the Hall sensor 21 monitors the rotation speed of the driving wheel 11, which is installed on the axle of the driving wheel 11 outside the housing of the gearbox 10; two tilt sensors 22 are installed outside the housing of the gearbox 10 and in a position to avoid interference, vibration, and impact, and are kept parallel to the gearbox 10, one of which monitors the roll angle of the gearbox 10, and the other monitors the pitch angle of the gearbox 10; the temperature sensor 23 monitors the internal temperature of the gearbox 10, which is installed inside the housing of the gearbox 10 and avoids affecting the lubrication; the resistance level sensor 24 monitors the oil height, which is installed in the housing of the gearbox 10, at the bottom of the lubricating oil; the absolute pressure sensor 25 monitors the internal air pressure, which is installed inside the housing of the gearbox 10 and avoids affecting the lubrication; the information collected by the sensor 20 reflects the various working conditions of the gearbox 10 during splash lubrication, and these working condition information are used as data, namely working condition data, and the working condition data is transmitted to the lubrication simulation analysis module, and the simulation calculation can be performed after the simulation model is set accordingly. At the same time, the working condition data collected by the sensor 20 is also transmitted to the intelligent training module as input to generate prediction data;

[0020] Specifically, the lubrication simulation analysis module is composed of fluid simulation software based on the particle method, such as particleworks, preonlab, shondy, etc., which are multi-physics field simulation analysis software that can perform lubrication simulation analysis of the gearbox 10, output the lubricating oil liquid volume fraction, and calculate the amount of lubricating oil. According to the various working condition data transmitted by the sensor 20, the corresponding working condition conditions are set in the simulation software, and monitoring sections or windows are set for important parts such as the bearing area and the gear meshing area. Then, through simulation calculation, the evaluation data reflecting the good or bad lubrication effect can be obtained and output: such as the amount of lubricating oil in the bearing area, the oil liquid volume fraction at the gear meshing area, etc. Finally, the working condition data and the lubrication effect evaluation data are merged into a multi-working condition simulation data set (this data set does not have to calculate all the collected working conditions, only some typical working conditions, and the specific number can be appropriately increased or decreased according to the computing power of the computer);

[0021] Specifically, the working condition data and lubrication effect evaluation data together constitute a multi-working condition simulation data set, which drives the intelligent training module. The module uses a machine learning model (such as a BP neural network) to perform deep mining and regression training on the multi-working condition data set, and quickly analyzes the real-time working condition data collected by the sensor 20, and generates the lubrication effect evaluation data predicted by the model in real time (when there is new input data, the model can generate corresponding output data based on the patterns and rules it has learned). The generated prediction data is used by the early warning decision module to analyze and judge the risk of insufficient lubrication;

[0022] Specifically, the early warning decision module is mainly composed of a main control unit and a lubrication shortage risk analysis unit. The main control unit obtains the prediction data generated by the intelligent training module, and the lubrication shortage risk analysis unit analyzes and judges the prediction data through threshold comparison. For the prediction data less than the threshold, the main control unit triggers the above-mentioned speaker to issue a warning. If the number of risk warnings reaches 3 within the specified time, the vehicle will be stopped and left to stand for 1 hour (to allow the lubricating oil to fully flow back to the bottom), and the main control unit will control the oil pump to open and pump the lubricating oil in the oil reservoir 30 into the gearbox 10, so that the oil is kept within the factory-set liquid level height range to prevent a large oil stirring power loss;

[0023] Specifically, through simulation analysis, a monitoring window is set for the lubrication area of ​​the bearing part, and the lubricating oil flow rate at the location can be obtained from the simulation results. For the bearing part of the gearbox 10 commonly used in passenger cars, when the lubricating oil flow rate is in the range of 0.1-0.3L / min, the lubrication effect is better. Therefore, the threshold of the lubricating oil flow rate of the bearing part in the early warning decision module can be set to 0.1L / min. If the lubricating oil flow rate of the bearing part in the corresponding predicted data is less than the threshold, the speaker is triggered to sound an alarm;

[0024] Specifically, through simulation analysis, a monitoring window is set for the lubrication area at the gear meshing, and the lubricating oil liquid integral fraction at the meshing area can be obtained in the simulation result. For the meshing area of ​​the gearbox 10, when the oil liquid integral fraction is continuous and the minimum value is not less than 0.6, the lubrication effect is good. Therefore, the threshold value of the oil liquid integral fraction at the gear meshing in the early warning decision module can be set to the oil liquid integral fraction being continuous and the minimum value being not less than 0.6. If the oil liquid integral fraction at the gear meshing in the corresponding prediction data is less than the threshold, the speaker is triggered to sound an alarm.
