Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of clutch monitoring for vehicles, and in particular to a device for monitoring the temperature of rotating components of a clutch assembly. BACKGROUND

[0002] The clutch is the first assembly of the transmission system, and the driving part thereof is connected to the flywheel of the engine through a motion shaft, and the driven part is connected to the gearbox. When the vehicle shifts gears, the clutch friction plate and the driven disc and the pressure plate will slide and generate heat. When the road is congested, the vehicle crawls at low speed, the clutch is frequently combined and separated, and is in a semi-linked state for a long time. The temperature of the clutch rises continuously, and serious burning phenomenon may occur. If a clutch temperature sensor is installed on a commercial vehicle, the excessively high temperature of the clutch caused by road conditions, operation methods or other reasons can be effectively identified, and the driver can take necessary intervention measures in time to avoid the burning phenomenon and improve the service life of the clutch.

[0003] Since the clutch is a rotating component, the industry usually uses a non-contact temperature measurement method to measure the temperature of the rotating component. Non-contact temperature measurement is achieved through the thermal radiation effect between the measured object and the temperature sensing element. For example, the reading of the infrared temperature measurement on a shiny or polished metal surface is greatly affected.

[0004] In Chinese patent CN115217872A, a clutch temperature measurement device and assembly method for a whole vehicle are also disclosed, which includes a thermocouple arranged on the surface of the clutch pressure plate. The temperature measurement lead of the thermocouple is led out from the back of the clutch pressure plate, passes through a hole to the back of the flywheel, and then passes through the engine crankshaft to the shock absorber on the front end face of the engine crankshaft. A temperature storage device is installed on the front end of the shock absorber and electrically connected to the temperature measurement lead.

[0005] However, due to some factors, the accuracy of temperature measurement is generally not high:

[0006] 1. The non-contact temperature measurement method is easily affected by environmental factors, such as ambient temperature, dust, and fog.

[0007] 2. It is only limited to measuring the external temperature of the object, and cannot measure the internal and external temperatures of the object in real time, resulting in low accuracy.

[0008] To solve the above problems, a device for monitoring the temperature of the clutch friction plate is provided, which can monitor the rotating components of the clutch in real time. SUMMARY

[0009] The embodiments of the present application provide a device for monitoring the temperature of rotating components of a clutch assembly to solve the problem of low accuracy and inconvenience of real-time monitoring of the existing rotating component temperature measurement device in the related art.

[0010] This application provides a device for monitoring the temperature of rotating components of a clutch assembly, including:

[0011] A rotating component, comprising a flywheel, a pressure plate, a friction plate disposed between the flywheel and the pressure plate, and a motion shaft for driving and connecting the flywheel, the pressure plate and the friction plate;

[0012] The friction plate has a countersunk hole, and the flywheel has a blind hole;

[0013] A temperature measuring mechanism is used to measure the real-time temperature of a rotating component. The temperature measuring mechanism includes a first temperature measuring unit that measures the internal temperature of the friction plate through a countersunk hole in the friction plate, and a second temperature measuring unit that measures the surface temperature of the friction plate through a blind hole in the flywheel.

[0014] In some embodiments, the first temperature measuring unit includes:

[0015] The first temperature sensor is disposed in the countersunk hole of the friction plate;

[0016] A first conductive copper ring is disposed inside the motion shaft;

[0017] The first heat-resistant wire is used to connect the first temperature sensor and the first conductive copper ring.

[0018] In some embodiments, a first brush is provided on the first conductive copper ring;

[0019] The first brush is pressed onto the first conductive copper ring by the first spring.

[0020] In some embodiments, the motion shaft has a first groove for placing a first conductive copper ring;

[0021] A first insulator is provided between the first groove and the first conductive copper ring.

[0022] In some embodiments, the second temperature measuring unit includes:

[0023] The second temperature sensor is disposed in the blind hole of the flywheel;

[0024] The second conductive copper ring is disposed on the moving shaft;

[0025] The second heat-resistant wire is used to connect the second temperature sensor and the second conductive copper ring.

[0026] In some embodiments, a second brush is provided on the second conductive copper ring;

[0027] The second brush is pressed onto the second conductive copper ring by a second spring.

[0028] In some embodiments, the motion shaft is further provided with a second groove for placing a second conductive copper ring;

[0029] A second insulator is provided between the second groove and the second conductive copper ring.

[0030] In some embodiments, the flywheel is further provided with a third spring for bringing the second temperature sensor into contact with the friction plate.

[0031] In some embodiments, the first heat-resistant conductor is a composite material.

[0032] In some embodiments, the first heat-resistant conductor is wrapped with an insulating tube.

[0033] This application provides a device for monitoring the temperature of rotating components in a clutch assembly. During clutch operation, a first temperature sensor installed inside the friction plate transmits the internal temperature of the friction plate in real time to a first brush via a first heat-resistant wire. The temperature signal is then transmitted to a display instrument for display. This allows for real-time monitoring of the internal temperature of the friction plate, avoiding the problem of only measuring the external temperature, which leads to unclear internal temperature, temperature data deviation, reduced accuracy, and reduced efficiency.

[0034] During clutch operation, while the friction plates monitor their internal temperature in real time, a second temperature sensor is located in a blind hole in the flywheel. The opening of the blind hole faces the friction plates, and the measuring end of the second temperature sensor extends out of the blind hole to contact the friction plates. As the friction plates rotate, they continuously contact the second temperature sensor. The second temperature sensor compresses the third spring behind it, causing it to retract. Then, the spring's rebound force causes it to retract and contact the friction plates again. This allows the sensor to continuously measure the surface temperature of the friction plates. This avoids the problem of the second temperature sensor having a fixed extension length. If the extension length is too long, it will jam the friction plates, damaging both the friction plates and the second temperature sensor. If the extension length is too short, it will not be able to contact the friction plates for temperature measurement, reducing the accuracy of temperature measurement.

[0035] By monitoring the external and internal temperatures of the friction plates in real time, the accuracy of temperature measurement for rotating components is further improved, thereby extending the lifespan of the rotating components and providing a better understanding of their real-time status.

[0036] Non-infrared temperature measurement also improves the accuracy of temperature measurement and avoids significant impact on readings on bright or polished metal surfaces.

[0037] The first and second heat-resistant conductors are made primarily of copper wire. In areas where the first heat-resistant conductor needs to be bent or is prone to bending, a more flexible and durable guide wire is used instead of copper wire. This not only meets the installation error requirements for temperature measurement but also increases the lifespan of the first and second heat-resistant conductors. It also prevents the first and second heat-resistant conductors from being bent for extended periods at bends or areas prone to bending, which could lead to breakage or damage.

[0043] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0044] This application provides a device for monitoring the temperature of rotating components of a clutch assembly, which solves the problems of existing rotating component temperature measuring devices being inconvenient for real-time detection and having low accuracy.

[0045] See Figures 1-3As shown, this application embodiment provides a device for monitoring the temperature of rotating components of a clutch assembly, including:

[0046] Rotating component and temperature measuring mechanism, the temperature measuring mechanism is used to measure the real-time temperature of the rotating component.

[0047] The rotating components include a flywheel 11, a pressure plate 22, a friction plate 1 disposed between the flywheel 11 and the pressure plate 22, and a motion shaft 5 for driving and connecting the flywheel 11, the pressure plate 22 and the friction plate 1.

[0048] When the vehicle starts, the driver depresses the clutch, and the pressure plate 22 separates from the friction plate 1. At this time, the pressure plate 22 is not in contact with the flywheel 11 at all. When the vehicle is driving normally, the pressure plate 22 is pressed tightly against the friction plate 1 of the flywheel 11. At this time, the friction between the pressure plate 22 and the friction plate 1 is relatively large, and the input shaft and the output shaft maintain relative static friction. The two rotate at the same speed. When the clutch is partially depressed, the friction between the pressure plate 22 and the friction plate 1 is small, and the pressure plate 22 of the clutch and the friction plate 1 on the flywheel 11 are in a state of sliding friction. The speed of the flywheel 11 is greater than the speed of the output shaft, and the power transmitted from the flywheel is transmitted to the gearbox.

[0049] When the vehicle starts, the friction plate 1 contacts the flywheel 11. At this time, the internal temperature of the friction plate 1 can be measured by the first temperature measuring unit. This avoids the situation where only the external temperature measuring unit measures the surface temperature of the friction plate 1, which would prevent real-time monitoring and cause the friction plate 1 to be damaged and unable to be replaced in time if the internal temperature is too high to be monitored.

[0050] When the vehicle is in motion, the flywheel 11 contacts the friction plate 1. At this time, the outer surface temperature of the friction plate 1 can be continuously measured by the second temperature measuring unit, and the outer surface temperature of the friction plate 1 can be monitored in real time. At the same time, the first temperature measuring unit inside the friction plate 1 is also monitoring in real time. This state allows the first and second temperature measuring units to work simultaneously, improving the overall monitoring of the friction plate 1 and improving the accuracy of the temperature measurement of the friction plate 1. It avoids the problem of insufficient temperature measurement and large temperature deviation caused by a single measurement method, which would prevent the driver and the vehicle's computer system from correctly judging the state of the friction plate 1.

[0051] The friction plate 1 has a countersunk hole, and the flywheel 11 has a blind hole.

[0052] The temperature measuring mechanism is used to measure the real-time temperature of the rotating component. The temperature measuring mechanism includes a first temperature measuring unit that measures the internal temperature of the friction plate 1 through the countersunk hole of the friction plate 1, and a second temperature measuring unit that measures the surface temperature of the friction plate 1 through the blind hole of the flywheel 11.

[0053] The first temperature sensor 2 of the first temperature measuring unit is set in the countersunk hole of the friction plate 1, and then connected to the first conductive copper ring 4 on the motion shaft 5 through the first heat-resistant wire 6, so that the temperature data can be transmitted to the display instrument through the first brush 8.

[0054] The second temperature sensor 10 of the second temperature measuring unit is installed in the blind hole of the flywheel 11, and then connected to the second conductive copper ring 12 on the motion shaft 5 through the second heat-resistant wire 13, so that the temperature data can be transmitted to the display instrument through the second brush 16.

[0055] By measuring the internal and external temperatures of friction plate 1 in real time, the temperature of rotating components can be monitored at all times, maintaining the working efficiency of the clutch and avoiding the situation where only the external temperature is measured, which may lead to the internal temperature being too high and thus causing the clutch to be damaged or even fail.

[0056] In some alternative embodiments, see Figure 1 and Figure 3 As shown, the first temperature measuring unit includes:

[0057] The first temperature sensor 2 is disposed inside the friction plate 1. The friction plate 1 has a blind hole, so that the first temperature sensor 2 is placed inside the blind hole, and then sealed with heat-resistant adhesive.

[0058] The first temperature sensor 2 can be a temperature sensor such as a thermocouple or a thermocouple.

[0059] The first conductive copper ring 4 is disposed inside the motion shaft 5.

[0060] The first heat-resistant wire 6 is used to connect the first temperature sensor 2 and the first conductive copper ring 4. One end of the first heat-resistant wire 6 is connected to the first temperature sensor 2 from the inside of the friction plate 1, and the other end extends from the friction plate 1 to the pressure plate 22 and then to the motion shaft 5. It then passes through the first groove 14 of the motion shaft 5 and connects with the first conductive copper ring 4 in the first groove 14, so that the first temperature sensor 2 is energized and transmits the temperature signal, and the first brush 8 outputs the temperature signal to the display instrument.

[0061] In this embodiment, a first brush 8 is connected to the first conductive copper ring 4. The temperature signal is transmitted to the display instrument through the first brush 8, so that the internal temperature of the friction plate 1 can be monitored in real time.

[0062] The first brush 8 is pressed onto the first conductive copper ring 4 by the first spring 9.

[0063] When the resistance of the first heat-resistant wire 6, the first conductive copper ring 4, and the first brush 8 is large, it will lead to an increase in contact voltage drop, which will affect the accuracy of the test data. Therefore, it is required that the contact resistance of the test system be as small as possible.

[0064] The greater the pressure of the first spring 9, the smaller the contact resistance between the first brush 8 and the first conductive copper ring 4, which is more conducive to improving the test accuracy. However, excessive pressure will cause excessive wear on the first brush 8 and the first conductive copper ring 4, which will affect normal operation. The contact pressure between the two should be controlled between 13 and 18g, and the contact resistance between the first brush 8 and the first conductive copper ring 4 should be controlled between 0.03 and 0.05Ω. The theoretical calculation of the contact resistance can refer to Formula 1.

[0065] R = K / F n ×10 3 Ω Equation 1

[0066] R: Contact resistance between the brush and the conductive copper ring;

[0067] K: Correlation coefficient with the properties of the materials constituting the contact surface and the contact form;

[0068] Point contact or line contact: 0.05~0.14;

[0069] Surface contact: 0.15~0.19;

[0070] n: A coefficient related to the contact surface pressure value and the number of contacts.

[0071] Point contact: 0.5;

[0072] Line contact: 0.75;

[0073] Surface contact: 0.8~1;

[0074] F: Contact pressure, unit: kgf

[0075] In this embodiment, a first groove 14 for placing a first conductive copper ring 4 is provided on the motion shaft 5, and a first insulator 15 is provided between the first groove 14 and the outer diameter of the first conductive copper ring 4.

[0076] There are several first conductive copper rings 4, which are arranged at equal intervals along the length of the motion axis 5. There are also several first grooves 14, which are matched with the first conductive copper rings 4.

[0077] The first insulator 15 can be made of insulating materials such as PEEK or fiberglass cloth.

[0078] In this embodiment, the first heat-resistant wire 6 is made of composite material.

[0079] The first heat-resistant conductor 6 is mainly made of copper wire. In some places where the first heat-resistant conductor 6 needs to be bent or is easily bent, a more flexible heat-resistant conductor is used instead of copper wire.

[0080] The first heat-resistant conductor 6 can be a composite wire composed of copper wire material in the main body and carbon nanotube fiber material at the bend, but it is not limited to a wire composed of copper wire and carbon nanotube fiber composite material. It can be applied to any heat-resistant material and heat-resistant and flexible material.

[0081] The carbon nanotube fibers contain single-walled carbon nanotubes and double-walled carbon nanotubes.

[0082] In this embodiment, the heat-resistant conductor material can be carbon fiber, copper wire, or other materials. The flexibility of carbon fiber is generally tested by the tensile strength of the knots, while copper wire is wound. Obviously, carbon fiber is more flexible than copper wire. That is, in this solution, the parts that are prone to bending can be replaced with more flexible carbon fiber conductors instead of copper wires. A comparison table of conductive material properties is attached:

[0083]

[0084] Table 1: Comparison of Conductive Material Properties

[0085] As shown in the table, the disadvantage of carbon fiber is its high resistivity, which makes it more prone to generating heat. To verify the effect of carbon fiber resistance on the temperature testing system, a 10cm long carbon fiber wire can be connected in series with the temperature testing system, and the difference in the instrument readings before and after the connection can be compared.

[0086] The display instrument used is AI-518, the temperature sensor is PT100, and the carbon fiber resistance is 3.6Ω~4.0Ω. Table 2 shows the temperature test results for carbon fiber and non-carbon fiber components.

[0087]

[0088] Table 2: Temperature Tests for Carbon Fiber and Non-Carbon Fiber Tests

[0089] The data shows that although carbon fiber has a high resistivity and is more prone to heating, its impact on the temperature testing system is small and within an feasible error range. Therefore, carbon nanotube fiber material can be used for the first heat-resistant wire 6 in places where bending is required and where bending is likely.

[0090] Carbon nanotube fiber wires can be of any length, depending on specific requirements. The wire resistance of carbon nanotube fiber wires is 0.5 ohms / cm.

[0091] The copper wire and carbon nanotube fiber wire are connected by crimping them together using terminals.

[0092] In this embodiment, the first heat-resistant conductor 6 is wrapped with an insulating tube 20. The insulating tube 20 is a ceramic insulating tube made of alumina ceramic to provide insulation and prevent leakage.

[0093] In some alternative embodiments, see Figures 1-3 As shown, the second temperature measuring unit includes:

[0094] The second temperature sensor 10 is disposed inside the flywheel 11, and a countersunk hole is opened on the flywheel 11 so that the second temperature sensor 10 is installed in the countersunk hole.

[0095] The second temperature sensor 10 also uses a temperature sensor such as a thermocouple or a thermocouple.

[0096] The second conductive copper ring 12 is disposed inside the motion shaft 5.

[0097] The second heat-resistant wire 13 is used to connect the second temperature sensor 10 and the second conductive copper ring 12.

[0098] One end of the second heat-resistant wire 13 is connected from the inside of the flywheel 11 to the second temperature sensor 10, and the other end extends from the inside of the flywheel 11 to the inside of the motion shaft 5, and then passes through the second groove 18 of the motion shaft 5, and is connected to the second conductive copper ring 12 in the second groove 18, so that the second temperature sensor 10 is energized and transmits temperature signals, and the second brush 16 outputs the temperature signals to the display instrument.

[0099] When the resistance of the second heat-resistant wire 13, the second conductive copper ring 12, and the second brush 16 is large, it will lead to an increase in contact voltage drop, which will affect the accuracy of the test data. Therefore, it is also required that the contact resistance of the test system be as small as possible.

[0100] Furthermore, when the pressure of the second spring 7 is greater, the contact pressure between the second brush 16 and the second conductive copper ring 12 is also controlled between 13 and 18 g, and the contact resistance between the second brush 16 and the second conductive copper ring 12 is also controlled between 0.03 and 0.05 Ω. The theoretical calculation of its contact resistance can refer to the above formula 1.

[0101] The second heat-resistant conductor 13 is also made of composite material, and has the same material and properties as the first heat-resistant conductor 6.

[0102] The second heat-resistant conductor 13 also uses copper wire as the main material. In some places where the first heat-resistant conductor 6 needs to be bent or is easily bent, a more flexible heat-resistant conductor is used instead of copper wire.

[0103] The second heat-resistant conductor 13 can be a composite wire composed of copper wire material as the main body and carbon nanotube fiber material at the bend, but it is not limited to a wire composed of copper wire and carbon nanotube fiber composite material. It can be applied to any heat-resistant material and heat-resistant and flexible material.

[0104] The experimental characteristics are described in Tables 1 and 2, and will not be explained here.

[0105] The second heat-resistant conductor 13 is also wrapped with an insulating tube 20. The insulating tube 20 is a ceramic insulating tube made of alumina ceramic to keep it insulated and prevent leakage.

[0106] In this embodiment, a second brush 16 is connected to the second conductive copper ring 12. The temperature signal is transmitted to the display instrument through the second brush 16, so that the external temperature of the friction plate 1 can be monitored in real time.

[0107] The second brush 16 is pressed onto the second conductive copper ring 12 by the second spring 7.

[0108] In this embodiment, a second groove 18 for placing the second conductive copper ring 12 is also provided on the motion shaft 5, and a second insulator 19 is provided between the second groove 18 and the outer diameter of the second conductive copper ring 12.

[0109] There are several second conductive copper rings 12, which are arranged at equal intervals along the length of the motion axis 5. There are also several second grooves 18, which are matched with the second conductive copper rings 12.

[0110] The second insulator 19 also uses insulating materials such as PEEK and fiberglass cloth.

[0111] In this embodiment, a third spring 21 is also provided inside the flywheel 11 for making the second temperature sensor 10 contact the friction plate 1.

[0112] The third spring 21 is disposed between the second temperature sensor 10 and the bottom of the blind hole, and the measuring end of the second temperature sensor 10 extends out of the blind hole and can contact the friction plate 1. By means of the third spring 21 behind it, the friction plate 1 is contacted with constant contact pressure, and the surface temperature of the friction plate 1 can be measured.

[0113] The working principle and process of this application:

[0114] During clutch operation, the internal temperature of the friction plate 1 can be transmitted in real time to the first brush 8 via the first heat-resistant wire 6 through the first temperature sensor 2 installed inside the friction plate 1. The temperature signal is then transmitted to the display instrument for display via the first brush 8. This allows for real-time monitoring of the internal temperature of the friction plate 1, avoiding the situation where only the external temperature can be measured, which would result in unclear internal temperature, temperature data deviation, reduced accuracy, and reduced efficiency.

[0115] During clutch operation, while the friction plate 1 monitors its internal temperature in real time, the second temperature sensor 10 is located in the blind hole of the flywheel 11. The opening of the blind hole faces the friction plate 1, and the measuring end of the second temperature sensor 10 extends out of the blind hole to contact the friction plate 1. As the friction plate 1 rotates, it continuously contacts the second temperature sensor 10. The second temperature sensor 10 compresses the third spring 21 behind it, causing it to retract. Then, the rebound force of the third spring 21 is used to rebound and contact the friction plate 1 again, allowing it to continuously measure the surface temperature of the friction plate. This avoids the problem of the second temperature sensor having a fixed extension length. If the length is too long, it will jam the friction plate, damaging both the friction plate and the second temperature sensor. If the length is too short, it will not be able to contact the friction plate for temperature measurement, reducing the accuracy of temperature measurement.

[0116] By monitoring the external and internal temperatures of the friction plate 1 in real time, the accuracy of temperature measurement of the rotating component is further improved, thereby extending the lifespan of the rotating component and providing a better understanding of its real-time status.

[0117] Non-infrared temperature measurement also improves the accuracy of temperature measurement and avoids significant impact on readings on bright or polished metal surfaces.

[0118] The first heat-resistant conductor 2 and the second heat-resistant conductor 13 are made primarily of copper wire. In some locations where the first heat-resistant conductor 6 needs to be bent or is prone to bending, a more flexible and durable guide wire is used instead of copper wire. This not only meets the installation error requirements for temperature measurement but also increases the lifespan of the first heat-resistant conductor 2 and the second heat-resistant conductor 13. It also prevents the first heat-resistant conductor 2 and the second heat-resistant conductor 13 from being bent for a long time at bending points or locations prone to bending, which could lead to breakage or damage.
