[0028] Reference Figure 1 , shows one of the schematic diagrams of a diaphragm spring provided in an embodiment of the present application; referring to Figure 2 , shows a second schematic diagram of a diaphragm spring provided in an embodiment of the present application. Figures 1 to 2 As shown, the diaphragm spring includes a diaphragm body 10 .

[0029] The diaphragm body 10 is provided with a first through-hole 101, and the first through-hole 101 passes through the diaphragm body 10. The diaphragm body 10 is further provided with a plurality of arc-shaped communicating holes 102 and a plurality of second through-holes 103. Each arc-shaped communicating hole 102 and each second through-hole 103 passes through the diaphragm body 10. The plurality of arc-shaped communicating holes 102 are spaced apart along the circumferential direction of the first through-hole 101, and the first end of each arc-shaped communicating hole 102 is connected to the first through-hole 101. A second penetration hole 103 is located at the second end of an arc-shaped connecting hole 102, and the second penetration hole 103 is connected to the arc-shaped connecting hole 102. Part of the diaphragm body 10 between two adjacent arc-shaped connecting holes 102 forms a separation finger 100, and the separation finger 100 bends along the bending direction of the arc-shaped connecting hole 102; wherein, the first penetration hole 101 is used to penetrate the rotating shaft 005 of the vehicle's gearbox, and the second penetration hole 103 is used to penetrate the hook 0011 on the vehicle's clutch cover 001.

[0030] In the embodiment of the present application, since a first penetration hole 101 is provided on the diaphragm body 10 and the first penetration hole 101 passes through the diaphragm body 10, when the diaphragm spring provided in the embodiment of the present application is applied to a vehicle, the rotating shaft 005 of the vehicle's gearbox can be passed through the first penetration hole 101. Since each arc-shaped communicating hole 102 and each second through-hole 103 penetrates the diaphragm body 10, multiple arc-shaped communicating holes 102 are spaced apart along the circumferential direction of the first through-hole 101, and the first end of each arc-shaped communicating hole 102 is communicated with the first through-hole 101, and one second through-hole 103 is located at the second end of one arc-shaped communicating hole 102, and the second through-hole 103 is communicated with the arc-shaped communicating hole 102. Therefore, along the circumferential direction of the first through-hole 101, the part of the diaphragm body 10 between any two adjacent second through-holes 103 and the arc-shaped communicating hole 102 forms a separation finger 100, and the separation finger 100 is arc-shaped, and the separation finger 100 is bent along the bending direction of the arc-shaped communicating hole 102, and the first end of the separation finger 100 is close to the first through-hole 101, and the separation finger 100 is close to the first through-hole 101. 0 is away from the first penetration hole 101, so that when the diaphragm spring provided by the embodiment of the present application is applied to a vehicle, the rotating shaft 005 of the gearbox is penetrated by the first penetration hole 101, and the hook 0011 on the clutch cover 001 of the vehicle is penetrated by the second penetration hole 103, so that once the clutch of the vehicle needs to be disengaged, the release bearing 006 on the rotating shaft 005 abuts against the release finger 100, and the first end of the arc-shaped release finger 100 is equivalent to the fulcrum, and the second end of the arc-shaped release finger 100 is equivalent to the force-bearing end, that is, the fulcrum is equivalent to the active end, and the second end of the release finger 100 is equivalent to the force-bearing end, so that under the premise that the size of the diaphragm body 10 remains unchanged, the force arm of the arc-shaped release finger 100 is longer, so that the separation force applied to the release finger 100 by the release bearing 006 can be reduced. That is, in the embodiment of the present application, a first perforation hole 101 is provided on the diaphragm body 10, and a plurality of arc-shaped connecting holes 102 and a plurality of second perforations 103 are provided. The plurality of arc-shaped connecting holes 102 are equivalent to being arranged at intervals around the first perforation hole 101, and one second perforation hole 103 is connected to one arc-shaped connecting hole 102, so that an arc-shaped separation finger 100 is formed in the area between two adjacent second perforations 103 and the arc-shaped connecting hole 102. Furthermore, under the premise that the size of the diaphragm body 10 remains unchanged, the force arm of the arc-shaped separation finger 100 is longer, so that after the diaphragm spring is applied to the vehicle, the separation force applied by the release bearing 006 on the rotating shaft 005 of the gearbox to the arc-shaped separation finger 100 can be reduced.

[0031] In the related art, the diaphragm spring includes a diaphragm body 10, and a first penetration hole 101, a plurality of strip-shaped connecting holes and a plurality of second penetration holes 103 can also be set on the diaphragm body 10. The first penetration hole 101, the connecting hole and the second penetration hole 103 all pass through the diaphragm body 10, and the plurality of connecting holes are spaced around the first penetration hole 101, and the second penetration hole 103 is arranged on one side of the connecting hole. One connecting hole is connected to one second penetration hole 103, and the plurality of connecting holes are all connected to the first penetration hole 101, so that along the circumferential direction of the first penetration hole 101, the area between two adjacent connecting holes and the second penetration hole 103 forms a linear separation finger. The first end of the linear separation finger is close to the first penetration hole 101, and the second end of the linear separation finger is away from the first penetration hole 101. Therefore, after the diaphragm spring in the related technology is applied to the vehicle, the rotating shaft 005 of the gearbox is penetrated into the first penetration hole 101. The first end of the linear separation finger is equivalent to the fulcrum, and the second end of the linear separation finger is equivalent to the force point. The force arm of the linear separation finger is the distance from the first end to the second end of the linear separation finger, and the force arm of the linear separation finger is shorter, resulting in a larger separation force to be applied.

[0032] In the embodiment of the present application, a first perforation hole 101 is provided on the diaphragm body 10, and a plurality of arc-shaped connecting holes 102 and a plurality of second perforation holes 103 are provided. The plurality of arc-shaped connecting holes 102 are equivalent to being arranged at intervals around the first perforation hole 101, and one second perforation hole 103 is connected to one arc-shaped connecting hole 102, thereby forming an arc-shaped separation finger 100 at a position between two adjacent second perforations 103 and the arc-shaped connecting hole 102. Compared with the linear separation finger in the related art, if the size of the diaphragm body 10 is kept unchanged, the first arc-shaped separation finger is kept unchanged. The positions of the two ends remain unchanged. The arc-shaped separation finger 100 of the present application is equivalent to adjusting the position of the first end, that is, it is equivalent to adjusting the position of the first end of the linear separation finger, so that the initial position of the first end of the linear separation finger is offset relative to the initial position of the linear separation finger, which is equivalent to extending the length of the lever arm of the linear separation finger, that is, the length of the lever arm of the arc-shaped separation finger 100 in the embodiment of the present application is greater than the length of the lever arm of the linear separation finger in the related art, which is equivalent to increasing the lever ratio of the separation finger 100 in the embodiment of the present application, so that the applied separation force is reduced.

[0033] In addition, in the embodiment of the present application, a first perforation hole 101 is provided on the diaphragm body 10, and a plurality of arc-shaped connecting holes 102 and a plurality of second perforations 103 are provided, so that an arc-shaped separation finger 100 is formed in the area between two adjacent second perforations 103 and the arc-shaped connecting holes 102. That is, in the embodiment of the present application, there is no need to additionally provide a separation finger 100 on the diaphragm body 10. The separation finger 100 and the diaphragm body 10 are an integrated structure, and the separation finger 100 and the diaphragm body 10 are located in the same plane. The separation finger 100 does not protrude from the diaphragm body 10, thereby reducing the space occupied by the diaphragm spring in the vehicle.

[0034] It should be noted that in the implementation of this application, the number of arcuate communicating holes 102 can be set according to actual needs. For example, the number of arcuate communicating holes 102 is 16, and another example is the number of arcuate communicating holes 102 is 8. The specific number of arcuate communicating holes 102 is not limited in this embodiment of the application. In addition, the number of second through-holes 103 is the same as the number of arcuate communicating holes 102.

[0035] In addition, in some embodiments, the center lines of the plurality of arc-shaped communication holes 102 are all bent in the same direction.

[0036] With this arrangement, the centerlines of the multiple arcuate communication holes 102 all curve in the same direction, which is equivalent to the arc line of each arcuate communication hole 102 bending in the same direction. This avoids the problem of two adjacent arcuate communication holes 102 bending in opposite directions, which would result in a limited number of arcuate communication holes 102. In other words, by setting the centerlines of each arcuate communication hole 102 to curve in the same direction, a larger number of arcuate communication holes 102 can be provided on the diaphragm body 10, thereby increasing the number of arcuate separation fingers 100, allowing the diaphragm spring to better meet actual needs.

[0037] Of course, in the embodiment of the present application, among the multiple arc-shaped communicating holes 102, the center lines of at least two arc-shaped communicating holes 102 may be bent in opposite directions. This embodiment of the present application does not limit this.

[0038] In addition, in the embodiment of the present application, the center line of each arc-shaped connecting hole 102 can be bent in the clockwise direction. Of course, the center line of each arc-shaped connecting hole 102 can also be bent in the counterclockwise direction. This embodiment of the present application does not limit this.

[0039] In addition, in some embodiments, the plurality of arcuate connecting holes 102 are evenly spaced along the circumferential direction of the first through-hole 101. With this arrangement, the arcuate separation fingers 100 formed between two adjacent arcuate connecting holes 102 and the second through-hole 103 are equivalent to the arcuate separation fingers 100 being evenly spaced along the circumferential direction of the first through-hole 101, that is, the first ends of the arcuate separation fingers 100 are evenly spaced along the circumferential direction of the first through-hole 101, and the second ends of the arcuate separation fingers 100 are evenly spaced along the circumferential direction of the first through-hole 101. Therefore, after the diaphragm spring provided by the embodiments of the present application is applied to a vehicle, when the release bearing 006 applies force to the plurality of separation fingers 100, the plurality of separation fingers 100 can be subjected to balanced force, and the diaphragm spring can transmit the force to the clutch cover 001 more evenly.

[0040] Additionally, in some embodiments, Figure 2 As shown, the area between two adjacent arc-shaped connecting holes 102 and two adjacent second through-holes 103 forms a separation finger 100. The length of the moment arm of separation finger 100 is L, satisfying the requirement of L > 70 mm. This arrangement allows the moment arm of separation finger 100 to be longer, thereby effectively increasing the leverage ratio of separation finger 100 and reducing the separation force applied to the diaphragm spring.

[0041] It should be noted that the length of the lever arm of the separation finger 100 can be set according to actual needs. For example, the length of the lever arm of the separation finger 100 is 80 mm, another example, the length of the lever arm of the separation finger 100 is 88.5 mm, and another example, the length of the lever arm of the separation finger 100 is 90 mm. This embodiment of the present application is not limited to this.

[0042] Of course, in the embodiment of the present application, the size of the diaphragm body 10 can also be set according to actual needs, so that the length of the force arm of the arc-shaped separation finger 100 can also be less than 70 mm. This embodiment of the present application does not limit this.

[0043] Additionally, in some embodiments, Figure 2 As shown, the width of the arc-shaped connecting hole 102 is M, which satisfies: 2mm≤M≤8mm. Through such an arrangement, the size of the arc-shaped separation finger 100 can be made appropriate, so that the separation finger 100 can effectively transmit force.

[0044] It should be noted that the width of the arc-shaped communicating hole 102 can be set according to actual needs. For example, the width M of the arc-shaped communicating hole 102 is 2 mm, another example, the width M of the arc-shaped communicating hole 102 is 3 mm, another example, the width M of the arc-shaped communicating hole 102 is 4 mm, another example, the width M of the arc-shaped communicating hole 102 is 6 mm, and another example, the width M of the arc-shaped communicating hole 102 is 8 mm. This embodiment of the present application is not limited to this.

[0045] Additionally, in some embodiments, Figure 1 or Figure 2 As shown, the first through hole 101 and the second through hole 103 are both circular holes, and the center line of the first through hole 101 coincides with the center line of the diaphragm body 10 .

[0046] By configuring both the first through-hole 101 and the second through-hole 103 as circular holes, when the diaphragm spring is applied to a vehicle, it is convenient for the transmission shaft 005 to penetrate the first through-hole 101, and it is also convenient for the hook 0011 on the clutch cover 001 to penetrate the second through-hole 103. Furthermore, the centerline of the first through-hole 101 coincides with the centerline of the diaphragm body 10, equivalent to the first through-hole 101 being positioned in the exact center of the diaphragm body 10. Consequently, once the transmission shaft 005 penetrates the first through-hole 101, when the release bearing 006 applies force to the arcuate release fingers 100, each arcuate release finger 100 receives a balanced force, and each arcuate release finger 100 is ensured to be of the same size, thereby improving the practicality of the diaphragm spring.

[0047] Of course, in the embodiment of the present application, the shape of the second through hole 103 can also be other shapes, for example, the second through hole 103 is a square hole, and another example is a hexagonal hole. The specific shape of the second through hole 103 is not limited in the embodiment of the present application.

[0048] In addition, in some embodiments, the diameter of the second penetration hole 103 can be greater than or equal to 1 mm. Through such a configuration, it can be ensured that the hook 0011 on the clutch cover 001 can be smoothly penetrated through the second penetration hole 103.

[0049] The diameter of the second through hole 103 may be 1 mm, or may be 2 mm. The specific value of the diameter of the second through hole 103 is not limited in this embodiment of the present application.

[0050] Additionally, in some embodiments, Figure 2As shown, the area between two adjacent arcuate connecting holes 102 and two adjacent second perforations 103 forms a separation finger 100. The distance N between the end of the separation finger 100 away from the first perforation 101 and the edge of the diaphragm body 10 satisfies the following requirement: N ≥ 10 mm. This arrangement allows for a greater distance between the arcuate separation finger 100 and the edge of the diaphragm body 10, ensuring the stability of the diaphragm spring.

[0051] It should be noted that the distance N between the end of the separation finger 100 away from the first perforation 101 and the edge of the diaphragm body 10 can be set according to actual needs. For example, the distance N between the end of the separation finger 100 away from the first perforation 101 and the edge of the diaphragm body 10 is 10 mm. For another example, the distance N between the end of the separation finger 100 away from the first perforation 101 and the edge of the diaphragm body 10 is 30 mm. This embodiment of the present application is not limited to this.

[0052] In addition, in some embodiments, the diaphragm body 10 is a circular plate. Through such an arrangement, when the diaphragm spring is applied to a vehicle, the diaphragm body 10 can be easily connected to the clutch cover 001 of the vehicle so that the diaphragm spring and the clutch cover 001 are adapted.

[0053] In the embodiment of the present application, since a first penetration hole 101 is provided on the diaphragm body 10 and the first penetration hole 101 passes through the diaphragm body 10, when the diaphragm spring provided in the embodiment of the present application is applied to a vehicle, the rotating shaft 005 of the vehicle's gearbox can be passed through the first penetration hole 101. Since each arc-shaped communicating hole 102 and each second through-hole 103 penetrates the diaphragm body 10, multiple arc-shaped communicating holes 102 are spaced apart along the circumferential direction of the first through-hole 101, and the first end of each arc-shaped communicating hole 102 is communicated with the first through-hole 101, and one second through-hole 103 is located at the second end of one arc-shaped communicating hole 102, and the second through-hole 103 is communicated with the arc-shaped communicating hole 102. Therefore, along the circumferential direction of the first through-hole 101, the part of the diaphragm body 10 between any two adjacent second through-holes 103 and the arc-shaped communicating hole 102 forms a separation finger 100, and the separation finger 100 is arc-shaped, and the separation finger 100 is bent along the bending direction of the arc-shaped communicating hole 102, and the first end of the separation finger 100 is close to the first through-hole 101, and the separation finger 100 is close to the first through-hole 101. 0 is away from the first penetration hole 101, so that when the diaphragm spring provided by the embodiment of the present application is applied to a vehicle, the rotating shaft 005 of the gearbox is penetrated by the first penetration hole 101, and the hook 0011 on the clutch cover 001 of the vehicle is penetrated by the second penetration hole 103, so that once the clutch of the vehicle needs to be disengaged, the release bearing 006 on the rotating shaft 005 abuts against the release finger 100, and the first end of the arc-shaped release finger 100 is equivalent to the fulcrum, and the second end of the arc-shaped release finger 100 is equivalent to the force-bearing end, that is, the fulcrum is equivalent to the active end, and the second end of the release finger 100 is equivalent to the force-bearing end, so that under the premise that the size of the diaphragm body 10 remains unchanged, the force arm of the arc-shaped release finger 100 is longer, so that the separation force applied to the release finger 100 by the release bearing 006 can be reduced. That is, in the embodiment of the present application, a first perforation hole 101 is provided on the diaphragm body 10, and a plurality of arc-shaped connecting holes 102 and a plurality of second perforations 103 are provided. The plurality of arc-shaped connecting holes 102 are equivalent to being arranged at intervals around the first perforation hole 101, and one second perforation hole 103 is connected to one arc-shaped connecting hole 102, so that an arc-shaped separation finger 100 is formed in the area between two adjacent second perforations 103 and the arc-shaped connecting hole 102. Furthermore, under the premise that the size of the diaphragm body 10 remains unchanged, the force arm of the arc-shaped separation finger 100 is longer, so that after the diaphragm spring is applied to the vehicle, the separation force applied by the release bearing 006 on the rotating shaft 005 of the gearbox to the arc-shaped separation finger 100 can be reduced.

[0054] An embodiment of the present application provides a clutch, which includes a clutch cover 001 and a diaphragm spring in any of the above embodiments; a plurality of hooks 0011 are provided on the clutch cover 001, one hook 0011 is penetrated through a second penetration hole 103, and the clutch cover 001 is used to abut against the engine flywheel 004.

[0055] It should be noted that, in the embodiments of the present application, Figure 3 As shown, the clutch may further include a support ring 002, which is disposed at the position where the hook 0011 penetrates the second penetration hole 103. The support ring 002 abuts against the diaphragm body 10 and can limit the position of the diaphragm body 10.
