[0056] The specific embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely intended to illustrate and explain the present application, and are not intended to limit the present application.

[0057] Participation Figure 1 As shown in the figure, the structure of an integrated monitoring system for the lubricating oil state of a gearbox and axle provided by the present application includes:

[0058] Gearbox 1 and axle 2, both of which are equipped with lubricating oil and installed on a vehicle;

[0059] Pipeline 3, which is connected to the gearbox 1 and the axle 2;

[0060] Valve 4, which is installed on the pipeline 3 and used to control the on-off of the lubricating oil between the gearbox 1 and the axle 2;

[0061] Lubricating oil quality sensor 5, which is installed in the pipeline 3 and used to monitor the state of the lubricating oil;

[0062] Control system 6, which is used to control the opening or closing of the valve 4 and to control the lubricating oil quality sensor 5 to monitor the state parameters of the lubricating oil when the valve 4 is opened and the lubricating oil in the gearbox 1 and the axle 2 flows to the pipeline 3, wherein the state parameters of the lubricating oil include at least one of the viscosity, acid value and particle content of the lubricating oil.

[0063] The valve 4 is used to control the communication of the lubricating oil in the gearbox and the lubricating oil in the axle, and when the communication is not needed, it ensures the stability of the lubricating oil level in the gearbox and the lubricating oil level in the axle, and ensures the reliability of operation.

[0064] In some embodiments, referring to Figure 1 As shown in the figure, the monitoring system further includes an oil pump 7 connected to the pipeline 3, which is used to pump the lubricating oil in the gearbox 1 and the axle 2 to the pipeline 3, so that the control system 6 controls the lubricating oil quality sensor to monitor the state of the lubricating oil.

[0065] The oil pump is used to provide power for the flow of the lubricating oil in the gearbox and the lubricating oil in the axle in the pipeline, and at the same time, the amount of lubricating oil in the gearbox and the amount of lubricating oil in the axle can be controlled based on the pumping direction of the oil pump.

[0066] In some embodiments, referring to Figure 1As shown, the integrated monitoring system further comprises an angle sensor 8 for monitoring the slope where the vehicle is located, so that the control system 6 controls the opening or closing of the valve 4 according to the slope to prevent excessive accumulation of lubricating oil in the gearbox 1 or axle 2;

[0067] a temperature sensor 9 for monitoring the temperature of the lubricating oil, so that the control system 6 determines whether to collect the lubricating oil state parameters monitored by the lubricating oil quality sensor 5 according to the temperature.

[0068] The gearbox and axle lubricating oil state monitoring system provided by the present application realizes the function of monitoring the lubricating oil in the gearbox and axle simultaneously by using one lubricating oil quality sensor through the oil pipe, which saves one sensor and reduces the cost compared with the traditional method. In addition, the control of the communication state of the lubricating oil in the gearbox and the lubricating oil in the axle is realized based on the valve, which avoids the disordered flow of the lubricating oil in the gearbox and the lubricating oil in the axle under the condition of excessive slope, and solves the problems of excessive and insufficient lubricating oil in the gearbox / axle.

[0069] Referring to Figure 2 As shown, the embodiment of the present application provides an implementation flowchart of a monitoring method applied to the integrated monitoring system of the lubricating oil state of the gearbox and axle, which comprises the following execution steps:

[0070] Step 200: When receiving the instruction of monitoring the state of the lubricating oil in the gearbox and axle of the vehicle, open the valve to make the lubricating oil in the gearbox and axle flow to the pipeline.

[0071] Step 201: Monitor the state parameters of the lubricating oil by using the lubricating oil quality sensor, and determine whether to issue an alarm information according to the relationship between the state parameters and the set threshold.

[0072] Among them, the state parameters of the lubricating oil include at least one of the viscosity, acid value and particle content of the lubricating oil.

[0073] According to the relationship between the state parameters and the set threshold, it is determined whether to issue an alarm information, for example, the change of the viscosity of the lubricating oil ≥10%, or the change of the acid value ≥1mg / g, or the iron content ≥2000ug / g, no pre-warning is issued, otherwise, an alarm information is issued to prompt the driver and other personnel of the state of the lubricating oil, and make maintenance planning and maintenance measures in advance.

[0074] In some embodiments, the monitoring method further comprises:

[0075] Obtaining the slope where the vehicle is located monitored by the angle sensor, and determining whether to open the valve according to the slope where the vehicle is located; if the slope where the vehicle is located is less than or equal to the preset slope threshold, the valve is opened; if the slope where the vehicle is located is greater than the preset slope threshold, the valve is not opened.

[0076] For example, -1%≤ slope information of the vehicle ≤ 1%, open the valve; slope information of the vehicle > 1% or < -1%, do not open the valve. It should be understood that the preset slope threshold can be set according to specific application scenarios, which is not limited herein.

[0077] It should be noted that -1%≤ slope information of the vehicle ≤ 1% means that the slope where the vehicle is located is approximately no slope, and the road is flat, and the slope information of the vehicle > 1% or < -1% means that there is a slope.

[0078] Based on the slope control valve of the vehicle, the communication between the lubricating oil in the gearbox and the lubricating oil in the axle is further controlled, which is communicated when the slope is small and is not communicated when the slope is large, thereby avoiding the risk of accumulation or too much lubricating oil in the gearbox or the axle.

[0079] In some embodiments, the monitoring method further comprises:

[0080] The acquisition step: acquiring the temperature information of the lubricating oil monitored by the temperature sensor;

[0081] The judgment step: judging whether to collect the lubricating oil state parameter monitored by the lubricating oil quality sensor according to the temperature information. If the temperature information of the lubricating oil is greater than or equal to the preset temperature threshold, the lubricating oil state parameter monitored by the lubricating oil quality sensor is collected. If the temperature information of the lubricating oil is less than the preset temperature threshold, the above-mentioned acquisition step and judgment step are continued to be executed cyclically.

[0082] It should be understood that when the temperature of the lubricating oil is low, the viscosity of the lubricating oil is high, and the flowability is poor, and local lubricating oil accumulation and other phenomena are easy to occur near the lubricating oil quality sensor probe, resulting in test distortion. When the temperature of the lubricating oil is increased, the viscosity of the lubricating oil is reduced, and the flowability is good, and the lubricating oil near the lubricating oil quality sensor probe flows smoothly, thereby ensuring that the lubricating oil quality data obtained by the test can represent the overall quality of the gearbox and the axle. Therefore, the present embodiment selects to collect the data of the lubricating oil quality sensor when the temperature of the lubricating oil is increased to 60℃, and it should be understood that the preset temperature threshold can be set according to specific application scenarios, which is not limited herein.

[0083] Further, when the temperature information of the lubricating oil ≥ 60℃, the data of the lubricating oil quality sensor is collected; when the temperature information of the lubricating oil < 60℃, the monitoring is continued, but no collection is performed.

[0084] When the lubricating oil reaches a certain temperature, the value of the lubricating oil quality sensor is collected, thereby avoiding the risk of data distortion of the lubricating oil quality sensor caused by too large viscosity of the lubricating oil at low temperature.

[0085] In some embodiments, the viscosity of the lubricating oil is calculated according to the following formula:

[0086]

[0087] In the formula, V represents the viscosity of the lubricating oil, T represents the input torque of the gearbox, n represents the input rotation speed of the gearbox, L represents the oil level of the lubricating oil of the gearbox, 、 、 represents the fitting coefficient of the gearbox.

[0088] In some embodiments, the acid value of the lubricating oil is calculated according to the following formula:

[0089]

[0090] In the formula, represents the acid value increase value of the lubricating oil caused by the oil stirring of a single gear per unit time, represents the temperature information of the gearbox, represents the acid value influence coefficient, and n represents the input rotation speed of the gearbox.

[0091] In some embodiments, the particle content of the lubricating oil is calculated according to the following formula:

[0092]

[0093] In the formula, C represents the mass percentage concentration of the iron content in the lubricating oil, represents the mass of the iron, represents the mass of the lubricating oil.

[0094] In some embodiments, referring to FIG. 5, which is a detailed implementation flowchart of a monitoring method of an integrated monitoring system for the lubricating oil state of a gearbox and an axle provided by an embodiment of the present application, the monitoring method comprises the following execution steps: Figure 3

[0095] S1: Obtain the gradient information of the vehicle and the temperature information of the lubricating oil.

[0096] Specifically, the gradient information of the vehicle can be obtained by measuring the angle sensor installed on the vehicle; and the temperature information of the lubricating oil can be obtained by monitoring the temperature sensor installed in the gearbox, the axle or the connecting pipeline of the gearbox and the axle.

[0097] S2: Determine whether the gradient information of the vehicle is greater than or equal to -1% and less than or equal to 1%. If yes, execute step S3, otherwise execute step S1.

[0098] S3: Open the valve, and the lubricating oil of the gearbox and the lubricating oil of the axle are communicated.

[0099] S4: Determine whether the temperature of the lubricating oil is greater than or equal to 60℃. If yes, execute step S5, otherwise execute step S1.​

[0100] S5: Obtain the value from the lubricating oil quality sensor.

[0101] S6: Determine whether the change in lubricating oil viscosity is less than 10%, or the change in acid value is less than 1 mg / g, or the iron content is less than 2000 ug / g. If yes, proceed to step S7; otherwise, proceed to step S1.

[0102] S7: Issue an alarm message.

[0103] In some implementations, see Figure 4 The diagram shown is a structural schematic of another integrated monitoring system for the lubricating oil status of the transmission and axle provided in an embodiment of the present invention, including... Figure 1 The components in this system differ from others in that a first valve and a second valve are provided in the pipeline. The first valve controls the connection between the transmission and the lubricating oil quality sensor, while the second valve controls the connection between the axle and the lubricating oil quality sensor. Specifically, it includes: a transmission 1, an axle 2, a pipeline 3, a first valve 4-1, a second valve 4-2, a lubricating oil quality sensor 5, and a control system 6. Both the transmission 1 and the axle 2 have lubricating oil for lubricating internal components such as gears and bearings, and are respectively installed on the vehicle. The pipeline 3 fluidly connects the lubricating oil in the transmission 1 and the lubricating oil in the axle 2. The first valve 4-1 is installed in the pipeline 3 to control the connection between the transmission 1 and the lubricating oil quality sensor 5.

[0104] The second valve 4-2 is installed in pipeline 3 to control the connection between the axle 2 and the lubricating oil quality sensor 5; the lubricating oil quality sensor 5 is installed in pipeline 3 to monitor the health status of the lubricating oil; the control system 6 is used to control the connection status of the valve 4. In an optional embodiment, the integrated monitoring system for the gearbox and axle lubricating oil status further includes an angle sensor 8 to monitor the gradient information of the vehicle's driving, and then transmits it to the control system 6 to control the connection status of the first valve 4-1 and the second valve 4-2.

[0105] In an optional embodiment, the integrated monitoring system for the lubricating oil status of the transmission and axle further includes a temperature sensor 9, which monitors the temperature of the lubricating oil in the axle, transmission, or pipeline, and then transmits the data to the control system 6 to control whether the lubricating oil quality sensor 5 collects lubricating oil quality data.

[0106] In a preferred embodiment, the lubricating oil quality sensor 5 is a multi-parameter sensor used to monitor one or more of the physicochemical properties of the lubricating oil, such as viscosity, acid value, and particle content.

[0107] In some implementations, for Figure 4The system structure monitoring method includes the following steps, see details below. Figure 5 As shown:

[0108] Step 500: Obtain the slope of the vehicle as detected by the angle sensor. If the slope of the vehicle is greater than or equal to the preset slope threshold, open the first valve; if the slope of the vehicle is less than or equal to the preset slope threshold, open the second valve.

[0109] For example, when the vehicle's slope information is ≤0%, the first valve 4-1 is opened; when the vehicle's slope information is >0%, the first valve 4-1 is not opened; when the vehicle's slope information is ≥0%, the second valve 4-2 is opened; when the vehicle's slope information is <0%, the first valve 4-2 is not opened.

[0110] It should be noted that a vehicle's slope information ≤0% means that the vehicle is on a slope that is approximately flat, while a vehicle's slope information ≥0% means that there is a slope.

[0111] Step 501: Obtain the temperature information of the lubricating oil monitored by the temperature sensor. If the temperature information is greater than or equal to a preset temperature threshold, collect the lubricating oil status parameters monitored by the lubricating oil quality sensor.

[0112] When the lubricating oil temperature is low, the lubricating oil viscosity is high and its fluidity is poor. This can easily lead to localized lubricating oil accumulation near the lubricating oil quality sensor probe, resulting in test distortion. As the lubricating oil temperature rises, its viscosity decreases and its fluidity improves. The lubricating oil flows smoothly near the lubricating oil quality sensor probe, ensuring that the tested lubricating oil quality data represents the overall quality of the transmission and axle. Therefore, this embodiment selects to start collecting data from the lubricating oil quality sensor after the lubricating oil temperature rises to 60°C. It should be understood that the preset temperature threshold can be set according to specific application scenarios and is not limited here.

[0113] Step 502: Based on the relationship between the lubricating oil status parameters and the set threshold, determine whether to issue an alarm message.

[0114] Specifically, when the quality indicators of the lubricating oil in the transmission and axle are detected to be out of standard, an alarm message is issued to inform the driver and other personnel of the lubricating oil status and to make maintenance plans and measures in advance.

[0115] See Figure 6 The diagram shown is a detailed implementation flowchart of another integrated monitoring method for the lubricating oil status of the transmission and axle provided by an embodiment of the present invention, including the following execution steps:

[0116] S10: Obtain vehicle gradient information and lubricating oil temperature information.

[0117] S20: Determine whether the vehicle slope information is less than or equal to 0%, if yes, execute step S40, otherwise execute step S10.

[0118] S30: Determine whether the vehicle slope information is greater than or equal to 0%, if yes, execute step S50, otherwise execute step S10.

[0119] S40: The second valve 4-2 is opened, and the axle lubricating oil is communicated with the sensor.

[0120] S50: The first valve 4-1 is opened, and the gearbox lubricating oil is communicated with the sensor.

[0121] S60: Determine whether the lubricating oil temperature is greater than or equal to 60℃, if yes, execute step S70, otherwise execute step S10.

[0122] S70: Obtain the lubricating oil quality sensor value.

[0123] S80: Determine whether the lubricating oil viscosity change is less than 10%, or the acid value change is less than 1mg / g, or the iron content is less than 2000ug / g, if yes, execute step S90, otherwise execute step S10.

[0124] S90: Issue an alarm information.

[0125] Through the above scheme, the first valve and / or the second valve can be opened separately according to the slope information to monitor the lubricating oil state, and whether the sensor value is collected is determined by monitoring the lubricating oil temperature. When the lubricating oil temperature is low, the lubricating oil viscosity is high, the flowability is poor, and local lubricating oil aggregation and other phenomena are easily formed near the lubricating oil quality sensor probe, which leads to test distortion. When the lubricating oil temperature is high, the lubricating oil viscosity is low, the flowability is good, the lubricating oil near the lubricating oil quality sensor probe flows smoothly, and the lubricating oil quality data obtained by the test can represent the overall quality of the gearbox and the axle.
