It includes a clutch friction plate drive disc, which is a stepped annular disc. Both the front and back sides of the drive disc are bolted with heat-conducting plates. By incorporating a heat dissipation device, when the temperature exceeds a preset trigger value, cooling oil, driven by an oil pump and guided by the oil passage space at the clutch edge, flows from the inlet into the cooling oil flow channel and then out from the outlet.

Description

Technical Field

[0001] This invention relates to the field of clutch friction plate technology, specifically to a low-wear automotive clutch friction plate and alarm system. Background Technology

[0002] Clutch friction plates function primarily through friction. Located between the engine and transmission, they transmit power. Therefore, friction generates a large amount of heat during operation. Existing friction plates only have traditional heat dissipation holes, making it impossible to control the heat dissipation process based on the actual temperature.

[0003] The existing clutch friction plates have the following defects:

[0004] 1. Application document US20180180136A1 ， The main consideration was to achieve a tight connection between the structures by forming a clutch damping system consisting of a pendulum body, a rolling structure, and an insert part, without considering how to achieve rapid heat dissipation while reducing the wear of the friction plates.

[0005] 2. The application document WO2016050569A1 mainly considers that if the torque applied to the torque limiter by the damping device is lower than the predetermined value, the damping device can be kept fixed to the hub and rotate with the hub. However, it does not consider real-time monitoring of the temperature on the friction plate to facilitate subsequent heat dissipation and alarm.

[0006] 3. Patent document CN110462240 mainly considers reducing viscous torque to facilitate smooth gear shifting, gear changing, and neutral shifting, but does not consider that existing friction plates cannot control the heat dissipation process according to temperature conditions, resulting in poor flexibility.

[0007] 4. Patent document CN112413018B mainly considers how to improve the accuracy of the wear judgment of the electronic clutch, but it cannot prompt the driver to take timely countermeasures when the friction plate shows abnormal temperature. Summary of the Invention

[0008] The purpose of this invention is to provide a car clutch friction plate with low wear and an alarm system to solve the problems mentioned in the background art.

[0009] To achieve the above objectives, the present invention provides the following technical solution: a low-wear automotive clutch friction plate, comprising a clutch friction plate drive disc, wherein the clutch friction plate drive disc is a stepped ring, and a heat-conducting base plate is bolted to both the front and back of the clutch friction plate drive disc. A heat dissipation device is provided inside the heat-conducting base plate and the clutch friction plate drive disc, wherein the heat dissipation device includes a cooling oil flow channel opened inside the clutch friction plate drive disc and multiple airflow channels opened inside the heat-conducting base plate. A liquid inlet is opened at the top of the clutch friction plate drive disc, and a liquid outlet is opened on the front of the clutch friction plate drive disc, wherein the liquid outlet is located to the side and below the liquid inlet.

[0010] Friction plates are bolted to the sides of both sets of heat-conducting base plates that are far apart from each other. A shock-absorbing plate is installed inside the friction plate. Four sets of heat dissipation holes are opened through the front of the shock-absorbing plate, and the two ends of the heat dissipation holes are smooth arc-shaped.

[0011] Preferably, the front of the shock absorber is provided with four sets of mounting slots, and the four sets of mounting slots are located between four sets of heat dissipation holes. Each of the four sets of mounting slots is equipped with a telescopic rod and a spring, and the spring is located on the outside of the telescopic rod. The front of the shock absorber is equipped with a driven disc hub, and the driven disc hub is located on the inside of the four sets of springs and heat dissipation holes.

[0012] Preferably, the clutch friction plate drive disc is equipped with two sets of temperature detection modules, and the temperature detection modules are located inside the cooling oil flow channel.

[0013] Preferably, the system includes a temperature information monitoring system, a data communication system, a data analysis system, a cooling control system, and an alarm system. The temperature information monitoring system is used to monitor the temperature of the two sets of friction plates and the heat-conducting base plate in real time. The data communication system is used to transmit the real-time temperature data monitored by the temperature information monitoring system to the data analysis system. The cooling control system is used to control the heat dissipation device to dissipate heat. The alarm system is used to alert the driver that the vehicle clutch temperature is abnormal.

[0014] Preferably, the temperature information monitoring system includes two sets of temperature detection modules, and the cooling control system includes a control valve and a trigger set value range. The control valve is used to control whether the cooling oil flows into the cooling oil flow channel and the airflow channel.

[0015] Preferably, the alarm system includes an anomaly detection module, a warning value range, and a display terminal. The anomaly detection module is used to determine whether the temperature has risen abnormally, and the display terminal includes an in-vehicle display screen to alert the driver that the vehicle clutch temperature is abnormal.

[0016] Preferably, the data analysis system includes a memory, a data processing unit, and a data scanning unit. The memory is used to store real-time temperature data monitored by the temperature information detection system. The data processing unit is used to clean and correct the real-time data in the memory. The data scanning unit is used to scan the processed data in real time to determine whether it exceeds the trigger set value range.

[0017] Preferably, the method of using this automotive clutch friction plate is as follows:

[0018] S1. First, the clutch friction plate drive plate, two sets of friction plates and heat-conducting base plate are assembled in the vehicle clutch. The temperature data on the friction plates and heat-conducting base plate are obtained in real time through the temperature detection module.

[0019] S2, the data communication system transmits the real-time temperature data monitored in S to the data analysis system for storage and scanning analysis. When the temperature exceeds the trigger set value range, the control valve is opened to allow the cooling oil to flow into the heat dissipation device for rapid heat dissipation.

[0020] S3. During the heat dissipation process, the temperature detection module monitors the temperature of the friction plate and the heat-conducting base plate in real time, and the anomaly judgment module determines whether there is an abnormal increase in temperature.

[0021] S4. After detecting an abnormal temperature rise that exceeds the warning range, an alarm signal is generated and sent to the vehicle display screen to remind the driver that the temperature of the vehicle's clutch has risen abnormally. Please stop driving immediately and have the vehicle inspected and repaired promptly.

[0022] Preferably, step S2 further includes the following steps:

[0023] S21. The data communication system sends the monitored real-time temperature data to the memory for storage. Then, the data processing unit cleans the temperature data in the memory and corrects any errors in the data. Next, the data scanning unit scans the processed temperature data to determine whether the temperature exceeds the trigger set value range.

[0024] S22. Once the temperature exceeds the trigger set value range, the data scanning unit sends a control signal to the cooling control system to open the control valve. The oil pump output is guided to the inlet using the oil passage space at the edge of the clutch and enters the cooling oil flow channel. Then it flows out from the outlet. Then, relying on the pressure and centrifugal force of the oil, the oil flows along the gap between the friction plate and the heat-conducting plate. Part of the oil flows into the airflow channel. Under the action of centrifugal force, the oil will flow to the outer edge of the heat-conducting plate and then fall back into the oil sump. The other part of the oil flows along the gap of the friction plate from the inner edge to the outer edge of the friction plate under the action of centrifugal force and then falls back into the oil sump. The cooling oil flowing through will carry away the heat on the clutch friction plate drive plate, friction plate and heat-conducting plate.

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] 1. This invention, equipped with a heat dissipation device, ensures that when the temperature exceeds a preset trigger value, cooling oil, driven by an oil pump and guided by the oil passage space at the edge of the clutch, flows from the inlet into the cooling oil flow channel and then out from the outlet. The oil then flows along the gap between the friction plates and the heat-conducting base plate. Part of the oil flows from one end of the inner edge of the heat-conducting base plate into the airflow channel, and under centrifugal force, flows out from the outer edge of the heat-conducting base plate and falls back into the oil sump. The flowing oil carries away the clutch friction plate drive disc and the heat-conducting base plate, achieving rapid cooling. Another portion of the oil flows along the gaps in the friction plates and, under the action of centrifugal force, from the inner edge to the outer edge of the friction plates, finally falling back into the oil sump. The oil carries away the heat from the friction plates, achieving rapid cooling and preventing the friction plates from being in a high-temperature environment for a long time, which would affect the service life of the clutch. Moreover, the cooling oil coats the surface of the friction plates. When the clutch is disengaged, the friction plates slip against each other due to the presence of oil pressure. When the clutch is engaged, the pressure applied squeezes out the oil in the middle of the friction plates, which can make the engagement very tight and transmit torque, effectively reducing clutch wear.

[0027] 2. This invention incorporates a temperature information monitoring system. Two sets of temperature detection modules monitor the temperature of the two sets of heat-conducting plates in real time. The real-time temperature data is transmitted to the data analysis system via a data communication system for storage, analysis, processing, and scanning. This facilitates the subsequent flow of cooling oil into the heat dissipation device to quickly dissipate heat from the clutch friction plates. Furthermore, when the temperature rises abnormally, an alarm system is triggered to alert the driver that the clutch temperature is abnormal.

[0028] 3. This invention is equipped with a cooling control system. The data scanning unit scans the processed data and compares it with the trigger set value range to determine whether it exceeds the trigger set value range. When the temperature exceeds the trigger set value range, a control command is sent to the cooling control system to open the control valve and allow the cooling oil to flow into the heat dissipation device. The flow of the cooling oil carries away the heat on the clutch friction plate drive disc, friction plate and heat-conducting base plate, thus achieving rapid heat dissipation.

[0029] 4. This invention incorporates an alarm system. During the heat dissipation process, the temperature detection module continuously monitors the temperature on the heat-conducting substrate in real time and transmits the data to the data analysis system for storage and processing. The anomaly detection module compares the processed data before and after to determine whether the temperature on the heat-conducting substrate shows a decreasing trend during the cooling process. If the anomaly detection module determines that the temperature of the heat-conducting substrate has abnormally increased and exceeds the warning value range during the heat dissipation process, it will send an alarm message to the display terminal, prompting the driver to immediately stop driving and promptly inspect and repair the vehicle to avoid danger caused by clutch failure.

[0043] Example 1

[0044] Please see Figure 1 , Figure 2 , Figure 4 and Figure 5 The present invention provides an embodiment of a low-wear automotive clutch friction plate, comprising a clutch friction plate drive disc 1, wherein the clutch friction plate drive disc 1 is a stepped ring, and a heat-conducting base plate 6 is bolted to both the front and back of the clutch friction plate drive disc 1. A heat dissipation device is provided inside the heat-conducting base plate 6 and the clutch friction plate drive disc 1. The heat dissipation device includes a cooling oil flow channel 4 opened inside the clutch friction plate drive disc 1 and multiple airflow channels 7 opened inside the heat-conducting base plate 6. A liquid inlet 3 is opened at the top of the clutch friction plate drive disc 1, and a liquid outlet 5 is opened at the front of the clutch friction plate drive disc 1, and the liquid outlet 5 is located to the side and below the liquid inlet 3.

[0045] Friction plates 2 are bolted to the sides of the two sets of heat-conducting base plates 6 that are far apart from each other. A shock-absorbing plate 12 is installed inside the friction plate 2. Four sets of heat dissipation holes 10 are opened through the front of the shock-absorbing plate 12, and the two ends of the heat dissipation holes 10 are smooth arc-shaped.

[0046] Furthermore, before using the automotive clutch friction plate, the clutch friction plate drive plate 1, two sets of friction plates 2, and two sets of heat-conducting plates 6 are assembled. Then, the assembled clutch friction plate is installed in the clutch, and the roller is fitted into the driven plate hub 13. The heat on the friction plate 2 is transferred to the clutch friction plate drive plate 1 via the heat-conducting plates 6. During subsequent use, when the temperature monitored by the temperature detection module 8 exceeds the trigger set value range, the control valve opens, and cooling oil enters the clutch under the delivery of the oil pump. Guided by the oil passage space at the edge of the clutch, the oil flows from the inlet 3 into the cooling oil flow channel 4, and then flows out from the outlet 5. The oil then flows along the gap between the friction plate 2 and the heat-conducting plates 6. Some oil flows from one end of the inner edge of the heat-conducting plates 6 into the airflow channel 7, and under the action of centrifugal force, flows out from the outer edge of the heat-conducting plates 6 and falls back into the oil sump. The flowing oil will carry away the friction plate drive plate 1 and the heat-conducting plates 6. The oil in plate 6 achieves rapid cooling. Another portion of the oil flows along the gaps of friction plate 2 from the inner edge to the outer edge under the action of centrifugal force, and finally falls back into the oil sump. The oil carries away the heat on friction plate 2, achieving rapid cooling and preventing friction plate 2 from being in a high-temperature environment for a long time, which would affect the service life of the clutch. The cooling oil is wrapped around the surface of friction plate 2. When the clutch is disengaged, friction plate 2 slips against each other due to the presence of oil pressure. When the clutch is engaged, the oil in the middle of friction plate 2 is squeezed out due to the applied pressure, so that the engagement is tight and torque is transmitted. This can effectively reduce clutch wear and thus extend the service life of the clutch. When the cooling device is not turned on, the airflow will enter the airflow channel 7 for heat dissipation due to the rotation of clutch friction plate drive plate 1 and friction plate 2. At the same time, the heat dissipation through hole 10 will assist in heat dissipation. Since the two ends of the heat dissipation through hole 10 are smooth arc-shaped, stress concentration can be effectively reduced.

[0047] Example 2

[0048] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The present invention provides an embodiment of a car clutch friction plate with low wear. The front of the shock absorber 12 has four sets of mounting slots, which are located between four sets of heat dissipation holes 10. Each of the four sets of mounting slots is equipped with a telescopic rod 11 and a spring 9, with the spring 9 located on the outside of the telescopic rod 11. The front of the shock absorber 12 is equipped with a driven disc hub 13, which is located inside the four sets of springs 9 and the heat dissipation holes 10.

[0049] The clutch friction plate drive disc 1 is equipped with two sets of temperature detection modules 8, and the temperature detection modules 8 are located inside the cooling oil flow channel 4.

[0050] Furthermore, the two clutch friction plates are driven by axial pressing and releasing. During the pressing and releasing process, there will be fluctuations. When the friction plate 2 is subjected to fluctuations, the spring 9 and heat dissipation hole 10 on the damping plate 12 will partially contract. After the fluctuations subside, the spring 9 and heat dissipation hole 10 will return to normal. The impact is reduced by the four sets of springs 9 and heat dissipation holes 10, avoiding the reduction of the service life of the clutch friction plate due to frequent impacts. When assembling the clutch friction plate and the clutch body, the roller shaft in the clutch is fitted into the driven plate hub 13.

[0051] The temperature detection module 8 monitors the temperature on the heat-conducting base plate 6 in real time. Since the heat-conducting base plate 6 is used to transfer the temperature on the friction plate 2 to the clutch friction plate drive disc 1, and the temperature on the heat-conducting base plate 6 is similar to that on the friction plate 2, the temperature detection module 8 can monitor the real-time temperature on the friction plate 2 and the heat-conducting base plate 6, which facilitates the subsequent analysis and processing of the monitored data.

[0052] Example 3

[0053] Please refer to Figures 1 and 2. An embodiment of the present invention provides an alarm system for a car clutch friction plate with low wear, including a temperature information monitoring system, a data communication system, a data analysis system, a cooling control system, and an alarm system. The temperature information monitoring system is used to monitor the temperature of the two sets of friction plates 2 and the heat-conducting base plate 6 in real time. The data communication system is used to transmit the real-time temperature data monitored by the temperature information monitoring system to the data analysis system. The cooling control system is used to control the heat dissipation device to dissipate heat. The alarm system is used to alert the driver that the vehicle clutch temperature is abnormal.

[0054] The temperature information monitoring system includes two sets of temperature detection modules 8.

[0055] Furthermore, the temperature information monitoring system is an integral part of the entire alarm system. The temperature information monitoring system includes two sets of temperature detection modules 8, which are mainly used to monitor the temperature of the heat-conducting base plate 6 and the friction plate 2 in real time. Since the friction plate 2 mainly uses friction for transmission, a large amount of heat energy is generated when the plates rub against each other, causing the temperature to rise. The temperature on the friction plate 2 will be transferred to the clutch friction plate drive disc 1 through the heat-conducting base plate 6. Therefore, the temperature monitored by the temperature detection module 8 is the temperature on the friction plate 2 and the heat-conducting base plate 6. The temperature detection module 8 monitors the temperature in real time and then transmits the real-time data to the data analysis system through the data communication system.

[0056] Example 4

[0057] Please refer to Figures 1 and 2. An embodiment of the present invention is provided: an alarm system for a car clutch friction plate with low wear. The data analysis system includes a memory, a data processing unit, and a data scanning unit. The memory is used to store real-time temperature data monitored by the temperature information detection system. The data processing unit is used to clean and correct the real-time data in the memory. The data scanning unit is used to scan the processed data in real time to determine whether it exceeds the trigger set value range.

[0058] The cooling control system includes a control valve and a trigger setpoint range. The control valve is used to control whether the cooling oil flows into the cooling oil flow channel 4 and the airflow channel 7.

[0059] Furthermore, the data is transmitted to the memory of the data analysis system for storage. Then, the data processing unit cleans the real-time data stored in the memory, corrects any errors in the data, and centrally organizes and analyzes the data. After that, the processed data is scanned and compared with the trigger set value range. When the scanned temperature information exceeds the trigger set value range, a control command is sent to the cooling control system to open the control valve, allowing the cooling oil to flow into the heat dissipation device. The flow of the cooling oil carries away the heat from the clutch friction plate active disc 1, friction plate 2, and heat-conducting base plate 6, achieving rapid heat dissipation.

[0060] Example 5

[0061] Please refer to Figures 1 and 2. An embodiment of the present invention provides an alarm system for a car clutch friction plate with minimal wear. The alarm system includes an anomaly judgment module, a warning value range, and a display terminal. The anomaly judgment module is used to determine whether the temperature has risen abnormally. The display terminal includes an in-vehicle display screen for alerting the driver to abnormal clutch temperature.

[0062] Furthermore, during the heat dissipation process, the temperature detection module 8 continues to monitor the temperature of the heat-conducting base plate 6 in real time and transmits the data to the data analysis system for storage and processing. The anomaly judgment module compares the processed data before and after to determine whether the temperature of the heat-conducting base plate 6 shows a downward trend during the heat dissipation process of the cooling oil. If the anomaly judgment module determines that the temperature of the heat-conducting base plate 6 has abnormally increased during the heat dissipation process, the data scanning unit will scan the data in real time and compare it with the warning value range. Once the temperature exceeds the warning value range, an alarm message will be sent to the display terminal to remind the driver that the clutch of the vehicle has an abnormally high temperature. The driver should stop driving immediately and check and repair it in time to avoid danger due to clutch failure.

[0063] Furthermore, the method of using this automotive clutch friction plate is as follows:

[0064] S1. First, the clutch friction plate drive plate 1, two sets of friction plates 2 and heat-conducting base plate 6 are assembled in the vehicle clutch. The temperature data on the friction plates 2 and heat-conducting base plate 6 are obtained in real time through the temperature detection module 8.

[0065] S2, the data communication system transmits the real-time temperature data monitored in S1 to the data analysis system for storage and scanning analysis. When the temperature exceeds the trigger set value range, the control valve is opened to allow the cooling oil to flow into the heat dissipation device for rapid heat dissipation.

[0066] S3. During the heat dissipation process, the temperature detection module 8 monitors the temperature of the friction plate 2 and the heat-conducting base plate 6 in real time, and the anomaly judgment module determines whether there is an abnormal increase in temperature.

[0067] S4. After detecting an abnormal temperature rise that exceeds the warning range, an alarm signal is generated and sent to the vehicle display screen to remind the driver that the temperature of the vehicle's clutch has risen abnormally. Please stop driving immediately and have the vehicle inspected and repaired promptly.

[0068] Step S2 further includes the following steps:

[0069] S21. The data communication system sends the monitored real-time temperature data to the memory for storage. Then, the data processing unit cleans the temperature data in the memory and corrects any errors in the data. Next, the data scanning unit scans the processed temperature data to determine whether the temperature exceeds the trigger set value range.

[0070] S22. Once the temperature exceeds the trigger set value range, the data scanning unit sends a control signal to the cooling control system, opens the control valve, and uses the oil passage space at the edge of the clutch to guide the oil output by the oil pump to the inlet 3 and into the cooling oil flow channel 4. Then it flows out from the outlet 5. Then, relying on the pressure and centrifugal force of the oil, the oil flows along the gap between the friction plate 2 and the heat-conducting base plate 6. Part of the oil flows into the airflow channel 7. Under the action of centrifugal force, the oil will flow to the outer edge of the heat-conducting base plate 6 and then fall back into the oil pool. The other part of the oil flows along the gap of the friction plate 2 from the inner edge to the outer edge of the friction plate 2 under the action of centrifugal force and then falls back into the oil pool. The cooling oil flowing through will carry away the heat on the clutch friction plate drive plate 1, the friction plate 2 and the heat-conducting base plate 6.

[0071] Working principle: Before using the clutch friction plate, first assemble the clutch friction plate drive plate 1, two sets of friction plates 2, and two sets of heat-conducting base plates 6. Then assemble the assembled clutch friction plate into the clutch, and it is ready to use. When the clutch is working, the temperature detection module 8 monitors the temperature on the heat-conducting base plates 6 in real time. The monitored data is transmitted to the memory for storage through the data communication system. The data processing unit cleans and analyzes the data in the memory. Then the data scanning unit scans and compares the processed data. When it is determined that the temperature exceeds the trigger set value range, a control command is sent to the cooling control system to open the control valve and allow the cooling oil to flow into the heat dissipation device. Under the action of oil pressure and centrifugal force, the cooling oil will eventually fall back into the oil sump. The flow of cooling oil carries away the heat on the clutch friction plate drive plate 1, friction plates 2, and heat-conducting base plates 6, achieving rapid heat dissipation.

[0072] Furthermore, during the heat dissipation process, the temperature detection module 8 continues to monitor the temperature of the heat-conducting substrate 6 in real time and transmits the data to the data analysis system for storage and processing. The anomaly judgment module compares the processed data with the data before and after. If the anomaly judgment module determines that the temperature of the heat-conducting substrate 6 has risen abnormally during the heat dissipation process, the data scanning unit will scan the data in real time and compare it with the warning value range. Once the temperature exceeds the warning value range, an alarm message will be sent to the display terminal to remind the driver that the vehicle's clutch has risen abnormally. The driver should stop driving immediately and have the clutch checked and repaired in time to avoid danger caused by clutch failure.

[0073] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

7. A low-wear warning system for automotive clutch plates as set forth in claim 4, characterized in that: The data analysis system includes a memory, a data processing unit, and a data scanning unit. The memory is used to store real-time temperature data monitored by the temperature information detection system. The data processing unit is used to clean and correct the real-time data in the memory. The data scanning unit is used to scan the processed data in real time to determine whether it exceeds the trigger set value range.

8. A method of using a low-wear automotive clutch plate according to any one of claims 4-7, characterized in that: The usage method of this car clutch friction plate is as follows: S1. First, the clutch friction plate drive plate (1), two sets of friction plates (2) and heat-conducting plate (6) are assembled in the vehicle clutch. The temperature data on the friction plates (2) and heat-conducting plate (6) are obtained in real time through the temperature detection module (8). S2, the data communication system transmits the real-time temperature data monitored in S1 to the data analysis system for storage and scanning analysis. When the temperature exceeds the trigger set value range, the control valve is opened to allow the cooling oil to flow into the heat dissipation device for rapid heat dissipation. S3. During the heat dissipation process, the temperature detection module (8) monitors the temperature of the friction plate (2) and the heat-conducting base plate (6) in real time, and the abnormal judgment module determines whether there is an abnormal increase in temperature. S4. After detecting an abnormal temperature rise that exceeds the warning range, an alarm signal is generated and sent to the vehicle display screen to remind the driver that the temperature of the vehicle's clutch has risen abnormally. Please stop driving immediately and have the vehicle inspected and repaired promptly.

9. The method of using a low-wear automotive clutch plate of claim 8, wherein, Step S2 further includes the following steps: S21. The data communication system sends the monitored real-time temperature data to the memory for storage. Then, the data processing unit cleans the temperature data in the memory and corrects any errors in the data. Next, the data scanning unit scans the processed temperature data to determine whether the temperature exceeds the trigger set value range. S22. Once the temperature exceeds the trigger set value range, the data scanning unit sends a control signal to the cooling control system, opens the control valve, and uses the oil passage space at the edge of the clutch to guide the oil pump output to the inlet (3) and enter the cooling oil flow channel (4). Then it flows out from the outlet (5). Then, relying on the pressure and centrifugal force of the oil, the oil flows along the gap between the friction plate (2) and the heat-conducting plate (6). Part of the oil flows into the airflow channel (7). Under the action of centrifugal force, the oil will flow to the outer edge of the heat-conducting plate (6) and then fall back into the oil pool. Another part of the oil flows along the gap of the friction plate (2) from the inner edge to the outer edge of the friction plate (2) under the action of centrifugal force and then falls back into the oil pool. The cooling oil flowing through will take away the heat on the clutch friction plate drive plate (1), friction plate (2) and heat-conducting plate (6).
