Description

TECHNICAL FIELD

[0001] The application relates to the clutch technical field, in particular to a friction plate with an alarm function for an automobile air conditioner clutch and a use method thereof. BACKGROUND

[0002] A clutch is needed on a compressor of an automobile air conditioner, and a friction plate is one of essential components of the clutch. When the friction plate contacts with a flywheel on the compressor, the friction plate will have a short-time relative friction sliding, the friction plate is prone to generate a large amount of heat, and the friction plate is prone to appear problems such as wear and bending during long-time use. In addition, the compressor is prone to appear oil seepage during long-time use, the oil seepage to the flywheel on the compressor is prone to cause the friction plate and the flywheel to continuously slide relative to each other due to oil lubrication, and the traditional friction plate for the clutch generally does not have an alarm function and cannot alarm when the friction plate is abnormal.

[0003] The existing composite door has the following defects:

[0004] 1. The patent document US20020043441A1 discloses a friction plate and a multi-plate clutch using the friction plate. The friction plate in the patent can prevent adjacent parts of the friction material segment from being peeled off or broken, but the friction plate cannot alarm when the temperature of the friction plate is abnormally high or the friction plate abnormally vibrates. Therefore, a friction plate for an automobile air conditioner clutch capable of alarming when the temperature of the friction plate is abnormally high or the friction plate abnormally vibrates is needed to solve the problem.

[0005] 2. The patent document US09109641B2 discloses a molded friction plate for a wet friction clutch. The friction plate in the patent does not have the function of scraping off the oil on the flywheel opposite to the friction plate. When the oil exists on the flywheel, the friction plate and the flywheel are prone to slide relative to each other for a long time, so that the friction plate cannot transmit the rotation of the flywheel. Therefore, a friction plate for an automobile air conditioner clutch capable of scraping off the oil on the flywheel opposite to the friction plate and having an alarm function is needed to solve the problem.

[0006] 3. The patent document JP2005273788A discloses a friction plate of a clutch device. The friction plate in the patent cannot store the oil falling on the flywheel opposite to the friction plate. The oil falling on the inner wall of the bottom of the clutch is prone to be continuously stained by the friction plate and the flywheel, which affects the friction effect of the friction plate and the flywheel. Therefore, a friction plate for an automobile air conditioner clutch capable of storing the oil on the inner wall of the bottom of the clutch and having an alarm function is needed to solve the problem.

[0007] 4、Patent document CN111828513B discloses a clutch friction plate and its manufacturing method and application. The friction plate in the patent cannot self-check whether the friction plate is bent. Long-time bending of the friction plate can easily affect the friction performance of the friction plate, and the bent part can also easily cause damage to the flywheel in long-time contact with the friction plate. Therefore, a friction plate with alarm function for automobile air conditioner clutch is needed to solve the problem. SUMMARY

[0008] One object of the present application is to provide a friction plate with alarm function for automobile air conditioner clutch and its use method, which can solve the technical problems in the prior art.

[0010] A second hydraulic cylinder is installed on the bottom inner wall of the mounting ring, and the second hydraulic cylinder is electrically connected with the controller, a second piston rod is installed on the output end of the second hydraulic cylinder, a dirt removal assembly is installed on one end of the second piston rod, and the dirt removal assembly is used to scrape off the oil stains on the flywheel of the compressor on which the friction plate body is installed.

[0011] Preferably, a friction material layer is installed on the back surface of the friction plate body, a plurality of first positioning holes are symmetrically installed on the front surface of the friction plate body, and a first mounting shaft hole is formed through the back surface of the friction plate body.

[0012] Preferably, a vibration sensor is installed on the inner wall of one side of the mounting ring, and the vibration sensor is electrically connected with the controller.

[0013] Preferably, a first hydraulic cylinder is symmetrically mounted on the inner wall of the mounting ring, and the first hydraulic cylinder is electrically connected to the controller. A first piston rod is mounted on the output end of the first hydraulic cylinder. A guide tube is movably mounted on the outer side of the first piston rod. A first pressure plate is mounted on one end of the guide tube. A pressure sensor is symmetrically mounted on the front side of the first pressure plate. The pressure sensor is electrically connected to the controller and is located inside the guide tube. Heat insulation cotton is mounted on the front side of the first pressure plate. A second mounting shaft hole is opened through the front side of the first pressure plate. A second positioning hole is symmetrically opened through the front side of the first pressure plate. The farthest stroke of the first piston rod can just drive the first pressure plate to contact the front side of the friction plate body. A second storage groove is opened through the front side of the first pressure plate.

[0014] Preferably, the decontamination assembly includes a first mounting frame and a first rubber pad. The front of the first mounting frame is connected to one end of the second piston rod, and the first rubber pad is installed through the back of the first mounting frame. A vibrator is installed on the front of the first mounting frame and is electrically connected to the controller.

[0015] Preferably, the decontamination assembly includes a second mounting frame and a rotating rod. The front of the second mounting frame is connected to one end of the second piston rod. The rotating rod is movably mounted through the inner side of the second mounting frame. A rubber sleeve is mounted on the outer side of the rotating rod. A second rubber pad is mounted on the inner wall of the back of the second mounting frame. A vibrator is mounted on the front of the second mounting frame and is electrically connected to the controller.

[0016] Preferably, an oil reservoir is installed on the front side of the friction plate body, an inlet pipe is installed at the input end of the oil reservoir, and one end of the inlet pipe penetrates the back side of the friction material layer. A first sponge is installed inside the oil reservoir, and a second sponge is installed inside the inlet pipe, with the second sponge connected to the first sponge.

[0017] Preferably, a pressure rod is movably installed through the front of the oil storage box, and a second pressure plate is installed at one end of the pressure rod.

[0018] Preferably, the method of using the friction plate for the automotive air conditioning clutch with alarm function is as follows:

[0019] S1. Install the friction plate body on the clutch, and then install the clutch end cover on the compressor. When the friction plate body moves towards the compressor flywheel and contacts the flywheel, if the friction plate body and the flywheel can make normal contact and there is no relative sliding between the friction plate body and the flywheel, then the friction plate body is in normal use.

[0020] S2. When there is relative sliding between the friction plate body and the flywheel, the friction plate body and the flywheel generate a lot of heat due to friction and sliding. The temperature sensor detects the temperature rise of the friction plate body and transmits the temperature information to the controller. The controller controls the alarm to sound an alarm.

[0021] S3. When the connection between the friction plate body and the clutch becomes loose, the friction plate body is also prone to vibration when it slides into contact with the flywheel. The vibration sensor can measure the vibration of the friction plate body and the mounting ring and transmit the vibration information to the controller. The controller then controls the alarm to sound an alarm.

[0022] S4. When the compressor leaks oil onto the flywheel, the second hydraulic cylinder can drive the first mounting frame to move backward so that the first rubber pad contacts the flywheel on the compressor. When the flywheel rotates, the first rubber pad can scrape off the oil on the surface of the flywheel, thereby reducing the possibility of slippage when the flywheel contacts the friction plate body due to too much oil on the flywheel. The scraped oil can flow along the first rubber pad to the bottom inner wall of the clutch, and then enter the oil reservoir through the inlet pipe. The second sponge can absorb the oil behind the friction plate body and enter the inlet pipe. The second sponge can transfer the oil to the first sponge, making it easier for the oil to enter the oil reservoir. The oil stored in the oil reservoir can store heat and absorb some of the heat of the friction plate body when the heat of the friction plate body increases, reducing the damage to the friction plate body caused by high temperature.

[0023] S5. When the friction plate body is damaged by bending, the first pressure plate can be moved backward by the first hydraulic cylinder. The first pressure plate is driven by the first hydraulic cylinder to the farthest stroke and just contact the front of the friction plate body. When the friction plate body is bent, the first pressure plate will generate pressure on the pressure sensor due to the pressure of the bent part of the friction plate body. When the pressure sensor measures the increase in pressure of the first pressure plate, it transmits the pressure information to the controller, and the controller controls the alarm to sound an alarm.

[0024] Preferably, step S4 further includes the following steps:

[0025] S41. When it is necessary to clean the oil inside the oil storage box, remove the friction plate body from the compressor, then press the pressure rod backward. The pressure rod moves backward and drives the second pressure plate to squeeze the first sponge, so that the oil inside the first sponge is discharged from the liquid inlet pipe, thereby realizing the discharge of the oil stored inside the oil storage box.

[0026] Compared with the prior art, the beneficial effects of the present invention are:

[0027] 1. In this invention, when the friction plate body moves towards and contacts the flywheel of the compressor, and there is relative sliding between the friction plate body and the flywheel, a large amount of heat is generated due to frictional sliding. The temperature sensor detects the temperature rise of the friction plate body, and the controller controls the alarm to sound. When the connection between the friction plate body and the clutch becomes loose, the friction plate body is also prone to vibration when it slides into contact with the flywheel. The vibration sensor can measure the vibration of the friction plate body and the mounting ring and transmit the vibration information to the controller. The controller controls the alarm to sound. This invention enables the friction plate of the automotive air conditioning clutch with alarm function to detect the temperature of the friction plate body through the temperature sensor and measure the vibration of the friction plate body and the mounting ring through the vibration sensor. When the temperature sensor detects a temperature rise or the vibration sensor detects abnormal vibration, the controller controls the alarm to sound.

[0028] 2. When the compressor leaks oil onto the flywheel, the invention can use a second hydraulic cylinder to move the first mounting frame backward, causing the first rubber pad to contact the flywheel on the compressor. As the flywheel rotates, the first rubber pad can scrape off the oil on the surface of the flywheel, thereby reducing the possibility of slippage when the flywheel contacts the friction plate body due to excessive oil on the flywheel. Similarly, the friction plate of the car air conditioning clutch with alarm function can be moved backward by the second hydraulic cylinder to make the first rubber pad contact the flywheel on the compressor. As the flywheel rotates, the first rubber pad can scrape off the oil on the surface of the flywheel, thereby reducing the possibility of slippage when the flywheel contacts the friction plate body due to excessive oil on the flywheel.

[0029] 3. This invention allows oil on the bottom inner wall of the clutch to enter the oil reservoir through the inlet pipe. The second sponge can absorb oil behind the friction plate body and enter the inlet pipe. The second sponge can then transfer oil to the first sponge, making it easier for the oil to enter the oil reservoir. Furthermore, the oil stored in the reservoir can store heat, absorbing some of the heat from the friction plate body when its temperature increases, reducing damage caused by high temperatures. When cleaning the oil in the reservoir is necessary, the friction plate body is removed from the compressor, and then the pressure rod is pressed backward. The pressure rod moves backward, causing the second pressure plate to press against the first... The sponge is squeezed to discharge the oil inside the first sponge through the inlet pipe, thereby discharging the oil stored in the oil reservoir. This allows the oil on the bottom inner wall of the clutch friction plate with alarm function to enter the oil reservoir through the inlet pipe. The second sponge can absorb the oil behind the friction plate body and enter the inlet pipe. The second sponge can then transfer the oil to the first sponge, making it easier for the oil to enter the oil reservoir. The oil stored in the oil reservoir can also store heat, absorbing some of the heat from the friction plate body when the heat increases, reducing damage to the friction plate body caused by high temperature.

[0030] 4. When the friction plate body is damaged by bending, the first pressure plate will exert pressure on the pressure sensor due to the pressure of the bent part of the friction plate body. When the pressure sensor measures an increase in the pressure of the first pressure plate, it transmits the pressure information to the controller. The controller then controls the alarm to sound an alarm. Attached Figure Description

[0046] The device includes a friction plate body 1 and a mounting ring 6. A friction material layer 2 is mounted on the back of the friction plate body 1. Multiple first positioning holes 3 are symmetrically mounted on the front of the friction plate body 1. A first mounting shaft hole 30 is formed through the back of the friction plate body 1. A temperature sensor 4 is mounted on the front of the friction plate body 1. A first receiving groove 5 is formed through the back of the friction plate body 1. The friction plate body 1 provides mounting positions for other components of the device, allowing them to be installed. The friction material layer 2 can contact the flywheel on the compressor, thereby increasing the friction between the friction plate body 1 and the flywheel, making it less prone to friction between them. The first positioning holes 3 serve a positioning function, allowing the friction plate body 1 to be precisely installed in the appropriate position inside the clutch. The first mounting shaft hole 30 can be fitted with a shaft inside the clutch, allowing the friction plate body 1 to be installed inside the clutch. The temperature sensor 4 measures the temperature of the friction plate body 1 and transmits the temperature information to the controller 7. A storage slot 5 provides storage space for either the first mounting frame 17 or the second mounting frame 24. A mounting ring 6 is mounted on the front of the friction plate body 1. A controller 7 is mounted on one inner wall of the mounting ring 6 and is electrically connected to the temperature sensor 4. An alarm 9 is mounted on one inner wall of the mounting ring 6 and is electrically connected to the controller 7. A vibration sensor 8 is mounted on one inner wall of the mounting ring 6 and is electrically connected to the controller 7.

The controller 7 can receive signals from the temperature sensor 4, the vibration sensor 8, and the pressure sensor 14, and control the alarm 9, the first hydraulic cylinder 10, the second hydraulic cylinder 15, and the vibrator 33. The controller 7 can also be electrically connected to the central control system of the vehicle, allowing the vehicle control system to control the controller 7. The alarm 9 can emit an alarm sound. The vibration sensor 8 can detect the vibration intensity of the friction plate body 1 and transmit the vibration information to the controller 7.

[0047] Please see Figure 1 , Figure 2 and Figure 4 One embodiment of the present invention is a friction plate for an automotive air conditioning clutch with an alarm function;

[0048] The system includes a first hydraulic cylinder 10 and a first pressure plate 12. The first hydraulic cylinder 10 is symmetrically mounted on the inner wall of the mounting ring 6 and is electrically connected to the controller 7. A first piston rod 11 is mounted on the output end of the first hydraulic cylinder 10. A guide tube 13 is movably mounted on the outer side of the first piston rod 11. The first pressure plate 12 is mounted on one end of the guide tube 13. Pressure sensors 14 are symmetrically mounted on the front side of the first pressure plate 12 and are electrically connected to the controller 7. The pressure sensors 14 are located inside the guide tube 13. The front of the plate 12 is fitted with heat insulation cotton 28. A second mounting shaft hole 31 is provided through the front of the first pressure plate 12. A second positioning hole 32 is symmetrically provided through the front of the first pressure plate 12. The maximum stroke of the first piston rod 11 can just drive the first pressure plate 12 to contact the front of the friction plate body 1. A second storage groove 34 is provided through the front of the first pressure plate 12. The first hydraulic cylinder 10 can convert hydraulic energy into kinetic energy, thereby driving the first piston rod 11 to move back and forth. The first piston rod 11 can drive the guide tube 13 by moving backward. Moving backward, the guide tube 13 can guide the first piston rod 11, allowing the first piston rod 11 to move back and forth inside the guide tube 13. The pressure sensor 14 can measure the pressure between the first piston rod 11 and the first pressure plate 12. The first pressure plate 12 can squeeze the front of the friction plate body 1. When the front of the friction plate body 1 bends, the first pressure plate 12 will exert pressure on the pressure sensor 14 due to the pressure of the bent friction plate body 1. After the pressure of the pressure sensor 14 increases, the controller 7 will control the alarm 9 to sound an alarm. The heat insulation cotton 28 plays a role in heat insulation, which can reduce the heat effect on the controller 7 when the friction plate body 1 generates heat due to friction. The second mounting shaft hole 31 allows the mounting shaft on the clutch to pass through, allowing the mounting shaft to enter the first mounting shaft hole 30 through the second mounting shaft hole 31. The second positioning hole 32 plays a positioning role, allowing the friction plate body 1 to be accurately installed in the appropriate position inside the clutch. The second storage groove 34 can provide storage space for the first mounting frame 17 or the second mounting frame 24.

[0049] Please see Figure 1 , Figure 2 , Figure 5 , Figure 6 , Figure 7 and Figure 8 One embodiment of the present invention is a friction plate for an automotive air conditioning clutch with an alarm function;

[0050] The second hydraulic cylinder 15 is installed on the bottom inner wall of the mounting ring 6 and is electrically connected to the controller 7. The output end of the second hydraulic cylinder 15 is equipped with a second piston rod 16. One end of the second piston rod 16 is equipped with a cleaning component, which is used to scrape off oil stains on the flywheel of the compressor on which the friction plate body 1 is mounted. The second hydraulic cylinder 15 can convert hydraulic energy into kinetic energy, thereby driving the second piston rod 16 to move back and forth. The second piston rod 16 can drive the first mounting frame 17 or the second mounting frame 24 to move back and forth by moving back and forth.

[0051] Please see Figure 1 , Figure 5 and Figure 6 One embodiment of the present invention is a friction plate for an automotive air conditioning clutch with an alarm function;

[0052] The cleaning assembly includes a first mounting frame 17 and a first rubber pad 18. The front of the first mounting frame 17 is connected to one end of the second piston rod 16, and the first rubber pad 18 is installed through the back of the first mounting frame 17. A vibrator 33 is installed on the front of the first mounting frame 17 and is electrically connected to the controller 7. The first mounting frame 17 provides a mounting position for the first rubber pad 18, allowing the first rubber pad 18 to be installed. At the same time, the first mounting frame 17 can move the first rubber pad 18 back and forth by moving back and forth. The first rubber pad 18 can contact the flywheel on the compressor by moving backward. When the flywheel rotates, it can scrape off the oil on the flywheel. The vibrator 33 can convert electrical energy into kinetic energy, thereby driving the first mounting frame 17 to vibrate, so that the oil on the first mounting frame 17 can flow downward faster.

[0053] Please see Figure 1 , Figure 7 and Figure 8 One embodiment of the present invention is a friction plate for an automotive air conditioning clutch with an alarm function;

[0054] The cleaning assembly includes a second mounting frame 24 and a rotating rod 26. The front of the second mounting frame 24 is connected to one end of the second piston rod 16. The rotating rod 26 is movably mounted through the inner side of the second mounting frame 24. A rubber sleeve 27 is mounted on the outer side of the rotating rod 26. A second rubber pad 25 is mounted on the inner wall of the back of the second mounting frame 24. A vibrator 33 is mounted on the front of the second mounting frame 24 and is electrically connected to the controller 7. The second mounting frame 24 provides a mounting position for the rotating rod 26, allowing the rotating rod 26 to be installed. 4. The rotating rod 26 can be moved back and forth by moving back and forth. The rotating rod 26 can provide an installation position for the rubber sleeve 27, so that the rubber sleeve 27 can be installed. The rubber sleeve 27 can scrape the oil off the flywheel by moving backward and contacting the flywheel on the compressor. Since the rotating rod 26 can rotate, the friction loss between the rubber sleeve 27 and the flywheel is small, and the life of the rubber sleeve 27 is longer. The vibrator 33 can convert electrical energy into kinetic energy, thereby driving the second mounting frame 24 to vibrate, so that the oil on the second mounting frame 24 can flow downward faster.

[0055] Please see Figure 1 , Figure 3 and Figure 9 One embodiment of the present invention is a friction plate for an automotive air conditioning clutch with an alarm function;

[0056] The friction plate body 1 includes an oil reservoir 19 and a pressure rod 22. The oil reservoir 19 is mounted on the front side of the friction plate body 1. An inlet pipe 20 is installed at the input end of the oil reservoir 19, and one end of the inlet pipe 20 penetrates the back side of the friction material layer 2. A first sponge 21 is installed inside the oil reservoir 19, and a second sponge 29 is installed inside the inlet pipe 20, and the second sponge 29 is connected to the first sponge 21. A pressure rod 22 is movably mounted through the front side of the oil reservoir 19, and a second pressure plate 23 is installed at one end of the pressure rod 22. The oil reservoir 19 serves to store oil and provides an installation position for the first sponge 21. The first sponge 21 can be installed, and the inlet pipe 20 can provide a transmission path for the oil inside the clutch to enter the oil reservoir 19. The first sponge 21 can absorb oil, so that the oil can be stored inside the oil reservoir 19. The second sponge 29 can absorb the oil behind the friction plate body 1, so that the oil can more easily enter the inlet pipe 20. The pressure rod 22 can drive the second pressure plate 23 to move back and forth by moving back and forth. The second pressure plate 23 can squeeze the first sponge 21 by moving backward, so that the oil inside the first sponge 21 is squeezed out, which facilitates the discharge of the oil inside the oil reservoir 19.

[0057] The usage method for the friction plate of the car air conditioning clutch with alarm function is as follows:

[0058] S1. Install the friction plate body 1 on the clutch, and then install the clutch end cover on the compressor. When the friction plate body 1 moves toward the compressor flywheel and contacts the flywheel, if the friction plate body 1 and the flywheel can make normal contact and there is no relative sliding between the friction plate body 1 and the flywheel, then the friction plate body 1 is in normal use.

[0059] S2. When there is relative sliding between the friction plate body 1 and the flywheel, the friction plate body 1 and the flywheel generate a lot of heat due to friction and sliding. The temperature sensor 4 detects the temperature rise of the friction plate body 1 and transmits the temperature information to the controller 7. The controller 7 controls the alarm 9 to issue an alarm.

[0060] S3. When the connection between the friction plate body 1 and the clutch becomes loose, the friction plate body 1 is also prone to vibration when it slides into contact with the flywheel. The vibration sensor 8 can measure the vibration of the friction plate body 1 and the mounting ring 6 and transmit the vibration information to the controller 7. The controller 7 controls the alarm 9 to issue an alarm.

[0061] S4. When the compressor leaks oil onto the flywheel, the second hydraulic cylinder 15 can drive the first mounting frame 17 to move backward so that the first rubber pad 18 contacts the flywheel on the compressor. When the flywheel rotates, the first rubber pad 18 can scrape off the oil on the surface of the flywheel, thereby reducing the possibility of slippage when the flywheel contacts the friction plate body 1 due to too much oil on the flywheel. The scraped oil can flow along the first rubber pad 18 to the bottom inner wall of the clutch, and then enter the oil storage box 19 from the inlet pipe 20. The second sponge 29 can absorb the oil behind the friction plate body 1 into the inlet pipe 20. The second sponge 29 can transfer the oil to the first sponge 21, making it easier for the oil to enter the oil storage box 19. The oil stored in the oil storage box 19 can store heat and absorb some of the heat of the friction plate body 1 when the heat increases, reducing the damage to the friction plate body 1 caused by high temperature.

[0062] S5. When the friction plate body 1 is damaged by bending, the first pressure plate 12 can be moved backward by the first hydraulic cylinder 10. The first pressure plate 12, driven by the first hydraulic cylinder 10, just contacts the front of the friction plate body 1 at its farthest stroke. When the friction plate body 1 is bent, the first pressure plate 12 will exert pressure on the pressure sensor 14 due to the pressure of the bent part of the friction plate body 1. When the pressure sensor 14 measures the increase in pressure of the first pressure plate 12, it transmits the pressure information to the controller 7. The controller 7 controls the alarm 9 to issue an alarm.

[0063] S4 also includes the following steps:

[0064] S41. When it is necessary to clean the oil inside the oil storage box 19, the friction plate body 1 is removed from the compressor, and then the pressure rod 22 is pressed backward. The pressure rod 22 moves backward and drives the second pressure plate 23 to squeeze the first sponge 21, so that the oil inside the first sponge 21 is discharged from the liquid inlet pipe 20, thereby realizing the discharge of the oil stored inside the oil storage box 19.

[0065] Working Principle: Before using the friction plate of the car air conditioning clutch with alarm function, it should be checked whether there are any problems affecting its use. First, install the friction plate body 1 on the clutch, and then install the clutch end cover on the compressor. When the friction plate body 1 moves towards and contacts the flywheel of the compressor, if the friction plate body 1 and the flywheel can make normal contact and there is no relative slippage between them, then the friction plate body 1 is in normal use. When there is relative slippage between the friction plate body 1 and the flywheel, a large amount of heat is generated due to friction. The temperature sensor 4 detects the temperature of the friction plate body 1. The temperature rises and transmits the temperature information to the controller 7. The controller 7 controls the alarm 9 to sound an alarm. When the connection between the friction plate body 1 and the clutch becomes loose, the friction plate body 1 is also prone to vibration when it slides into contact with the flywheel. The vibration sensor 8 can measure the vibration of the friction plate body 1 and the mounting ring 6 and transmit the vibration information to the controller 7. The controller 7 controls the alarm 9 to sound an alarm. When the compressor leaks oil onto the flywheel, the second hydraulic cylinder 15 can drive the first mounting frame 17 to move backward so that the first rubber pad 18 contacts the flywheel on the compressor. When the flywheel rotates, the first rubber pad 18 can scrape off the oil on the surface of the flywheel, thereby reducing the risk of too much oil on the flywheel causing friction between the flywheel and the friction plate. There is a possibility of slippage when the body 1 contacts. The scraped oil can flow along the first rubber pad 18 to the bottom inner wall of the clutch, and then enter the oil reservoir 19 through the inlet pipe 20. The second sponge 29 can absorb the oil behind the friction plate body 1 and enter the inlet pipe 20. The second sponge 29 can transfer the oil to the first sponge 21, making it easier for the oil to enter the oil reservoir 19. The oil stored in the oil reservoir 19 can store heat. When the temperature of the friction plate body 1 increases, it absorbs part of the heat of the friction plate body 1, reducing the damage to the friction plate body 1 caused by high temperature. When the friction plate body 1 suffers bending damage, the first pressure plate 12 can be moved backward by the first hydraulic cylinder 10. Driven by a hydraulic cylinder 10, the furthest stroke of the cylinder just contacts the front of the friction plate body 1. When the friction plate body 1 bends, the first pressure plate 12 will exert pressure on the pressure sensor 14 due to the pressure of the bent part of the friction plate body 1. When the pressure sensor 14 measures the increase in pressure of the first pressure plate 12, it transmits the pressure information to the controller 7. The controller 7 controls the alarm 9 to sound an alarm. When it is necessary to clean the oil inside the oil storage box 19, the friction plate body 1 is removed from the compressor, and then the pressure rod 22 is pressed backward. The pressure rod 22 moves backward and drives the second pressure plate 23 to squeeze the first sponge 21, so that the oil inside the first sponge 21 is discharged from the inlet pipe 20, thereby realizing the discharge of the oil stored inside the oil storage box 19.

Install the friction plate body (1) on the clutch, and then install the clutch end cover on the compressor. When the friction plate body (1) moves toward the compressor flywheel and contacts the flywheel, if the friction plate body (1) and the flywheel can make normal contact and there is no relative sliding between the friction plate body (1) and the flywheel, then the friction plate body (1) is in normal use.
