Description

Technical Field

[0001] The present invention relates to the technical field of vehicles, and in particular to a clutch temperature measuring device and a vehicle. Background Art

[0002] The clutch is a key core component in the vehicle. In order to ensure the smooth transmission of transmission power and the smooth driving of the vehicle during the vehicle's starting and shifting, the clutch must maintain a large sliding speed difference, but this will also generate a large amount of friction heat. If the temperature of the clutch friction plate is too high and the heat generated is not dissipated in time, it will have a great impact on the service life and performance stability of the friction plate group, and thus affect the performance of the vehicle. Therefore, it is necessary to detect the temperature of the friction plate through a clutch temperature measuring device.

[0003] Some clutch temperature measuring devices in the prior art are used in bench tests, but this test scheme is inconsistent with the high-speed rotation state of the friction plate when the actual vehicle is working. The reliability of test temperature and other data is low, and it cannot more truly reflect the actual temperature of the clutch friction plate under the actual vehicle driving state. Some are also used in actual vehicles, and the temperature of the friction plate is detected by a temperature sensor embedded in the outer friction plate of the friction plate. The temperature sensor is usually connected to a transmitting module through a wire, so that the temperature parameter detected by the temperature sensor is transmitted to an external terminal through the transmitting module. The transmitting module is usually set on the inner damping plate of the friction plate. The wire crosses the inner damping plate and the outer friction plate and the wire is exposed. The wire lacks protection and is easily damaged. In addition, the outer friction plate and the inner damping plate will swing back and forth relative to each other when the clutch is working, which can easily cause the wire to be damaged.

[0042] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0043] Some clutch temperature measuring devices in the prior art are used in bench tests, but this test scheme is inconsistent with the high-speed rotation state of the friction plate when the actual vehicle is working. The reliability of test temperature and other data is low, and it cannot more truly reflect the actual temperature of the clutch friction plate under the actual vehicle driving state. Some are also used in actual vehicles, and the temperature of the friction plate is detected by a temperature sensor embedded in the outer friction plate of the friction plate. The temperature sensor is usually connected to a transmitting module through a wire, so that the temperature parameter detected by the temperature sensor is transmitted to an external terminal through the transmitting module. The transmitting module is usually set on the inner damping plate of the friction plate. The wire crosses the inner damping plate and the outer friction plate and the wire is exposed. The wire lacks protection and is easily damaged. In addition, the outer friction plate and the inner damping plate will swing back and forth relative to each other when the clutch is working, which can easily cause the wire to be damaged.

[0044] In this regard, this embodiment provides a clutch temperature measuring device to solve the above problem.

[0045] Please refer to Figures 1 to 5 The clutch temperature measuring device includes a friction plate 1, a temperature sensor 2, a transmitting module 3, a wire 4, a first bracket 5 and a second bracket 6.

[0046] The friction plate 1 includes an inner damping plate 11 and an outer friction plate 12 coaxially sleeved on the inner damping plate 11 . The outer friction plate 12 is connected to the inner damping plate 11 through a damping spring 13 , and the outer friction plate 12 can swing relative to the inner damping plate 11 .

[0047] Specifically, a plurality of damping springs 13 are connected between the outer friction disc 12 and the inner damping disc 11, and the plurality of damping springs 13 are evenly distributed along the circumferential direction of the inner damping disc 11, so that the outer friction disc 12 can swing relative to the inner damping disc 11 to a certain extent. In the acceleration condition and the braking condition, the relative swinging directions of the outer friction disc 12 and the inner damping disc 11 are opposite. Specifically, when the damping spring 13 is naturally extended, the relative swinging angle of the inner damping disc 11 and the outer friction disc 12 is 0°, and when the friction plate 1 is working, the relative swinging angle range between the outer friction disc 12 and the inner damping disc 11 is [-a, b], and the maximum relative swinging angle between the outer friction disc 12 and the inner damping disc 11 is β, β=a+b. In which, a and b are both positive numbers. By way of example, in this embodiment, a=9°, b=11°, and in other embodiments, the values ​​of a and b can also be set according to the specific model of the friction plate 1.

[0048] Please refer to Figure 1 The temperature sensor 2 is arranged on the outer friction plate 12 and is used to collect the temperature of the outer friction plate 12. The transmitting module 3 is arranged on the inner shock absorbing plate 11. The wire 4 is connected between the temperature sensor 2 and the transmitting module 3. The transmitting module 3 is used to send the temperature parameters detected by the temperature sensor 2 to the control terminal.

[0049] Specifically, the temperature sensor 2 is embedded in the outer friction disc 12 to protect the temperature sensor 2. In this embodiment, the probe of the temperature sensor 2 is exposed to the outer friction disc 12, and the probe of the temperature sensor 2 is slightly lower than the surface of the outer friction disc 12 to protect the temperature sensor 2 and facilitate the temperature sensor 2 to collect the real-time temperature of the surface of the outer friction disc 12 during the operation of the clutch.

[0050] Please refer to Figure 1 The first bracket 5 is installed on the outer edge of the inner damping plate 11, the second bracket 6 is installed on the inner edge of the outer friction plate 12, and the second bracket 6 and the first bracket 5 are staggered along the circumferential direction of the friction plate 1; the wire 4 includes a flexible wire 41, the first end of the flexible wire 41 is fixed to the first bracket 5, and the second end of the flexible wire 41 is fixed to the second bracket 6. The two ends of the flexible wire 41 are fixed by the first bracket 5 and the second bracket 6, which can constrain and protect the flexible wire 41 to a certain extent, and when the outer friction plate 12 swings back and forth relative to the inner damping plate 11, under the constraint of the first bracket 5 and the second bracket 6, the flexible wire 41 rolls and deforms synchronously, which can avoid prolonging the crease of the flexible wire 41 and prolong the service life of the flexible wire 41, thereby improving the reliability of the clutch temperature measuring device.

[0051] Please refer to Figure 6In this embodiment, the second bracket 6 and the first bracket 5 are staggered along the circumferential direction of the friction plate 1, which means that when the relative swing angle between the inner damping plate 11 and the outer friction plate 12 is 0°, the first bracket 5 and the second bracket 6 partially overlap and partially stagger in the circumferential direction of the friction plate 1, and the central angle of the friction plate 1 corresponding to the overlapping part of the first bracket 5 and the second bracket 6 is approximately 20°, and the central angle corresponding to the staggered part of the first bracket 5 and the second bracket 6 is approximately 4°. This arrangement can make up for the problem of inconsistent amplitudes of the outer friction plate 12 swinging in the forward and reverse directions relative to the inner damping plate 11.

[0052] Optionally, in this embodiment, the first bracket 5 is fixed to the inner damping plate 11 by a plurality of bolts 7, and the second bracket 6 is fixed to the outer friction plate 12 by a plurality of bolts 7. In other embodiments, the first bracket 5 may also be fixed to the inner damping plate 11 by gluing, and the second bracket 6 may be fixed to the outer friction plate 12 by gluing.

[0053] Optionally, see Figure 1 , the wire 4 also includes a first connecting wire 42 and a second connecting wire 43, the first connecting wire 42 is connected between the first end of the flexible wire 41 and the transmitting module 3, and the second connecting wire 43 is connected between the second end of the flexible wire 41 and the temperature sensor 2. The temperature parameter collected by the temperature sensor 2 is transmitted to the transmitting module 3 through the second connecting wire 43, the flexible wire 41 and the first connecting wire 42, and is wirelessly transmitted to the control terminal by the transmitting module 3. In this embodiment, the first connecting wire 42, the flexible wire 41 and the second connecting wire 43 can be separately arranged or integrally arranged.

[0054] Optionally, the first connecting wire 42 is fixed to the inner damping disc 11, and the second connecting wire 43 is fixed to the outer friction disc 12. The first connecting wire 42 and the second connecting wire 43 can be fixed by wire harness fixing or gluing.

[0055] Optionally, see Figures 2 to 6 , the flexible wire 41 is set to a U-shaped structure. It can be understood that the opening of the U-shaped structure is opened along the circumferential direction of the friction plate 1. When the first bracket 5 moves relative to the second bracket 6, the flexible wire 41 can always maintain the U-shaped structure, and the lengths of the two sides of the U-shaped structure increase and decrease, and the rolling deformation of the flexible wire 41 can avoid the generation of creases.

[0056] Optionally, the flexible conductor 41 is a cable having certain flexibility, and the arc bend of the U-shaped structure has certain tension, so that when the first bracket 5 moves relative to the second bracket 6, it can roll and deform well and maintain the shape of the U-shaped structure.

[0057] Optionally, see Figure 6The flexible wire 41 includes a first connecting section 411, a first buffer section 412, a rolling section 413, a second buffer section 414, and a second connecting section 415 connected in sequence. The first connecting section 411 is fixedly connected to the first bracket 5, and the first buffer section 412 and the first connecting section 411 are coplanar. The second connecting section 415 is fixedly connected to the second bracket 6, and the second buffer section 414 and the second connecting section 415 are coplanar. When the outer friction disc 12 swings relative to the inner damping disc 11, it will drive the rolling section 413 of the flexible wire 41 to roll. The rolling section 413 is U-shaped. During the rolling of the rolling section 413, the two sides of the U-shape increase and decrease. The first buffer section 412 and the second buffer section 414 are used to provide buffering during the rolling process of the flexible wire 41 to avoid stress concentration at the first connecting section 411 and the second connecting section 415, which may cause the flexible wire 41 to be damaged.

[0058] Optionally, see Figure 6 In this embodiment, the first connecting section 411 and the first buffer section 412 are both arc-shaped, the second connecting section 415 and the second buffer section 414 are both arc-shaped, and the center of the first connecting section 411, the center of the first buffer section 412, the center of the second connecting section 415 and the center of the second buffer section 414 all coincide with the center of the friction plate 1.

[0059] In this embodiment, the total length of the flexible wire 41 is L, and the lengths of the first connecting section 411 and the second connecting section 415 are both L. g The lengths of the first buffer section 412 and the second buffer section 414 are both L h The maximum swing angle of the outer friction plate 12 relative to the inner damping plate 11 is β, and the radii of the first connecting section 411 and the first buffer section 412 are both N r The radius of the second connecting section 415 and the second buffer section 414 are both W r The distance between the first connecting section 411 and the second connecting section 415 along the radial direction of the friction plate 1 is 2R, and the length of the rolling section 413 is L u , the total length of the flexible conductor 41 satisfies the following formula:

[0060] L=L u +2*(L g +L h );L u =(N r +W r )*π*β / 360+(W r -N r )*π / 2.

[0061] Such a configuration can make the length of the rolling section 413 compatible with the set angle range of the outer friction plate 12 swinging relative to the inner damping plate 11. g , Lh , β, N r , W r The value of R can be set according to the specific model of the friction plate 1; R = W r -N r The distance between the first connecting segment 411 and the second connecting segment 415 along the radial direction of the friction plate 1 is the diameter of the arc portion of the rolling segment 413. Therefore, the radius of the arc portion of the rolling segment 413 is R.

[0062] Optionally, please refer to the figure, when the friction plate 1 rotates, airflow can be generated, and the opening of the U-shaped structure faces the direction of the airflow. In this way, under the action of the airflow, the flexible wire 41 can be tightened, especially for the rolling section 413. When the rolling section 413 is tightened, when the outer friction plate 12 swings relative to the inner damping plate 11, the rolling effect of the flexible wire 41 will be better, which can prevent the flexible wire 41 from being loosened and causing damage.

[0063] Optionally, see Figure 4 and Figure 5 The first bracket 5 is provided with a first arc groove 51, and the second bracket 6 is provided with a second arc groove 61. The center of the first arc groove 51 and the center of the second arc groove 61 are both coincident with the center of the friction plate 1. The notch of the first arc groove 51 and the notch of the second arc groove 61 are opposite to each other along the radial direction of the friction plate 1. Along the circumferential direction of the friction plate 1, the first arc groove 51 penetrates the first bracket 5, and the second arc groove 61 penetrates the second bracket 6; the first end of the flexible wire 41 is fixed to the bottom surface of the first arc groove 51, and the second end of the flexible wire 41 is fixed to the bottom surface of the second arc groove 61. Such a configuration can further constrain the position of the flexible wire 41, and can prevent the flexible wire 41 from being damaged by contact with other external components.

[0064] Optionally, see Figure 2 and Figure 3 The clutch temperature measuring device further includes a windshield 8, one end of which is connected to the second bracket 6, and the other end of which extends into the first arc groove 51; when the friction plate 1 rotates, airflow can be generated, and along the flow direction of the airflow, the windshield 8 is located upstream of the flexible wire 41. It can be understood that when the clutch is working, a large amount of airflow will be generated. By setting the windshield 8, the force of the airflow on the rolling segment 413 is reduced while ensuring that the rolling segment 413 can be tensioned by the airflow, so as to further protect the flexible wire 41.

[0065] Optionally, see Figure 1 The clutch temperature measuring device further comprises a battery 9 disposed on the inner damping plate 11, and the battery 9 is electrically connected to the transmitting module 3. The battery 9 is used to supply power to the transmitting module 3, and the battery 9 and the transmitting module 3 are electrically connected via a power supply line 10.

[0066] This embodiment also provides a vehicle, including the clutch temperature measuring device in the above solution, and the vehicle also includes a control terminal, which is communicatively connected to the transmitting module 3. The vehicle adopts the clutch temperature measuring device, and the wire 4 has a long service life, which can ensure the reliability of the clutch temperature measuring device.
