Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this application based on the specific circumstances.

[0051] This application discloses a novel flexible flywheel vibration damper.

[0052] Please see Figure 1 One embodiment of a novel flexible flywheel vibration damper provided in this application includes:

[0053] Flexible disk assembly 1, driven disk 2, flywheel body 3, clamping pad 4, and clamping elastic element 5.

[0054] The flywheel body 3 is mounted on the flexible disk assembly 1. Specifically, in order to better achieve the installation fit, the flywheel body 3 is provided with positioning holes and the flexible disk assembly 1 is provided with positioning bosses that are aligned and fitted with the positioning holes.

[0055] The driven disc 2 is installed on the side of the flywheel body 3 facing away from the flexible disc assembly 1, with the flywheel body 3 at the bottom and the pressing elastic element 5 at the top. Specifically, the driven disc 2 is installed on the flywheel body 3 in the center and upward.

[0056] The clamping elastic element 5 is installed on the side of the driven plate 2 facing away from the flywheel body 3, and the clamping pad 4 is installed between the driven plate 2 and the clamping elastic element 5; specifically, the clamping pad 4 clamps the elastic element 5 as a butterfly spring, with its small end facing the clamping pad 4 and installed on the clamping pad 4.

[0057] The flexible disk assembly 1 has multiple limiting members 13 arranged along its circumferential direction; the limiting members 13 can be bent and pressed against the pressing elastic member 5 to press the pressing elastic member 5 onto the pressing pad 4.

[0058] The gap between the limiting members 13 on the flexible disk assembly 1 can avoid the installation of the clamping pad 4, so that the clamping pad 4 can be installed on the driven disk 2 through the gap between the limiting members 13 on the flexible disk assembly 1.

[0059] The novel flexible flywheel vibration damper designed in this application has the following beneficial effects:

[0060] 1. By setting multiple circumferentially distributed and bendable limiting members 13 on the flexible disk assembly 1, the pressing elastic member 5 is pressed onto the pressing pad 4; by using the bent limiting members 13 in the form of bent claws to replace the traditional cover plate structure riveting form to press the pressing elastic member 5 onto the pressing pad 4, this design can eliminate the cover plate structure and assembly rivets, reduce the number of parts, and thus effectively reduce weight and achieve lightweighting.

[0061] 2. Compared with the traditional cover plate structure riveting method, the installation of the bending limiting part 13 to fasten and press the elastic part 5 is more convenient, which simplifies the production process, reduces production costs, and improves product competitiveness.

[0062] The above is Embodiment 1 of a novel flexible flywheel vibration damper provided in this application. The following is Embodiment 2 of a novel flexible flywheel vibration damper provided in this application. Please refer to the following for details. Figures 1 to 7 .

[0063] Based on the solution of Embodiment 1 above:

[0064] Furthermore, the limiting component 13 is integrally molded onto the flexible disc assembly 1. From a manufacturing perspective, the integral molding process simplifies the originally complex assembly process, reducing the manpower, material resources, and time costs associated with separately manufacturing and assembling the limiting component 13 and the flexible disc assembly 1, greatly improving production efficiency and enabling products to enter the market more quickly to meet the production needs of automakers. In terms of structural stability, integral molding avoids problems such as loosening and displacement that may occur in traditional connection methods. The limiting component 13 and the flexible disc assembly 1 are seamlessly integrated, maintaining precise engagement and clamping of the elastic component 5 even when the car is running at high speed, frequently starting and stopping, or encountering bumpy road conditions, ensuring stable operation of the flywheel shock absorber and effectively reducing the risk of failure. Regarding the goal of lightweighting, integral molding eliminates the weight of rivets and redundant connecting structures, while optimizing the overall structural layout, allowing the component to further reduce its weight while meeting mechanical performance requirements.

[0065] Furthermore, the limiting member 13 has a sheet-like structure. Compared to strip-like or rod-like structures, the sheet-like structure design allows for a larger contact area between the limiting member 13 and the clamping elastic member 5, thus better securing the clamping elastic member 5. From the perspective of production process adaptability, the sheet-like structure is relatively simple and regular, making it easier to achieve high-precision and high-efficiency mass production in mold manufacturing, injection molding, or stamping processes.

[0066] Furthermore, there are at least three limiting members 13, which are evenly distributed circumferentially. This increased number and even distribution of the limiting members 13 allows for more reliable pressing of the clamping elastic member 5 onto the clamping pad 4. The specific number of limiting members 13 can be varied according to actual needs, as described in this application. Figure 1 The design includes 9 limiting components.

[0067] Furthermore, such as Figure 2 As shown, the driven disc 2 includes a face riveting assembly 201, a first clamping plate 202, a second clamping plate 206, a third clamping plate 207, a vibration damping elastic assembly 203, a damping disc 204, a disc hub 205, a first driven elastic element 208, a second driven elastic element 209, and a clamping disc 210.

[0068] The first clamping plate 202 is fastened to the face riveting assembly 201; specifically, the first clamping plate 202 can be a nylon clamping plate type 1, with its four claws aligned and fastened into the four notches of the face riveting assembly 201 (the fastening and engagement of the claws and notches is an existing mating structure, which will not be described in detail).

[0069] The face riveting assembly 201 is provided with elastic mounting windows for the vibration damping elastic assembly 203 to be inserted; specifically, there are multiple elastic mounting windows, for example, 4, and there are 4 corresponding vibration damping elastic assemblies 203, which are inserted into the elastic mounting windows one by one and clamped.

[0070] The damping disc 204 is installed on the side of the first clamping plate 202 facing the clamping pad 4. Specifically, the process hole of the damping disc 204 is aligned with the process hole of the face riveting assembly 201 and is installed above the first clamping plate 202 (when the flywheel body 3 is below / the clamping elastic member 5 is above). The process hole is a hole structure with a corresponding fit, which will not be described in detail.

[0071] The hub 205 is mounted on the damping disc 204, and its external teeth mesh with the internal teeth in the middle of the damping disc 204.

[0072] The first driven elastic element 208 is installed on the second clamping plate 206. Specifically, the first driven elastic element 208 is a butterfly spring type 1, and the second clamping plate 206 is a nylon clamping plate type 2. The small end of the first driven elastic element 208 faces the second clamping plate 206 and is installed between the four claws of the second clamping plate 206. The four claws of the second clamping plate 206 are aligned and snapped into the claw holes of the clamping disk 210, thereby achieving the second clamping plate 206 being snapped onto the clamping disk 210.

[0073] The outer teeth of the third clamping plate 207 are aligned with the inner teeth of the clamping disc 210 and are mounted on the disc hub 205; specifically, the third clamping plate 207 is a nylon clamping plate type 3.

[0074] The second driven elastic element 209 is installed on the third pressing plate 207; specifically, the second driven elastic element 209 is a butterfly spring type 2, with its small end facing the third pressing plate 207 and installed on the third pressing plate 207.

[0075] The clamping disc 210 is riveted to the face riveting assembly 201 by limiting pins 211. Specifically, the process holes of the clamping disc 210 are aligned with the process holes on the face riveting assembly 201, and then riveted and fixed by multiple (e.g., four) limiting pins 211.

[0076] Furthermore, such as Figure 3 As shown, the vibration damping elastic component 203 includes a first vibration damping spring 2031 and a second vibration damping spring 2032, with the second vibration damping spring 2032 nested inside the first vibration damping spring 2031.

[0077] Furthermore, such as Figure 4As shown, the mounting window has a binding portion 6 on each of its two axial edges of the face riveting assembly 201. The binding portion 6 is used to restrict the vibration damping elastic assembly 203 in the axial direction of the face riveting assembly 201. By changing the traditional flange design of the window to a binding design, the application of the spring seat structure can be eliminated, thereby reducing the number of parts, saving installation steps and costs, and achieving the goal of lightweighting.

[0078] Furthermore, such as Figure 5 As shown, the face riveting assembly 201 includes a damping disk 2011 and a face plate assembly 2012; the face plate assembly 2012 is riveted to the damping disk 2011. Specifically, the rivet holes and process holes of the connecting piece 20122 in the face plate assembly 2012 are aligned with the rivet holes and process holes of the damping disk 2011, and the two are riveted together by solid rivets 2013.

[0079] Furthermore, such as Figure 6 As shown, the faceplate assembly 2012 includes a friction plate 20121 and a connecting plate 20122; the friction plate 20121 and the connecting plate 20122 are riveted together. Specifically, the rivet hole of the friction plate 20121 is aligned with the rivet hole of the connecting plate 20122, and the two are riveted together by a hollow rivet 20123.

[0080] Furthermore, the flexible disk assembly 1 includes a washer 12 and a flexible disk 11, with the washer 12 and the flexible disk 11 riveted together; specifically, the riveting hole of the washer 12 is aligned with the riveting boss of the flexible disk 11, and the two are riveted together to form the flexible disk assembly 1.

[0081] Correspondingly, the limiting member 13 is disposed on the flexible disk 11.

[0082] Specifically, the clamping plate 210 has its process holes aligned with the process holes of the damping plate 2011 and the damping plate 204, and is then riveted to the damping plate 2011 by four limit pins 211.

[0083] The above provides a detailed description of a novel flexible flywheel vibration damper provided in this application. For those skilled in the art, based on the ideas of the embodiments of this application, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this application.
