[0037] To more clearly illustrate the above-mentioned objectives, features, and advantages of this application, specific embodiments of this application are described in detail in conjunction with the accompanying drawings in this section. Besides the embodiments described in this section, this application can also be implemented in other different ways. Those skilled in the art can make corresponding improvements, modifications, and substitutions without departing from the spirit of this application; therefore, this application is not limited to the specific embodiments disclosed in this section. The scope of protection of this application should be determined by the claims.

[0038] (First Implementation)

[0039] like Figures 1 to 5 As shown, the first embodiment of this application proposes a spoke spring vibration damper, which includes a cover plate 1, a diaphragm spring 2, a support washer 3, a spoke assembly 4, a hub 5, an inner peripheral fastener 6, and an outer peripheral fastener 7. The spoke spring vibration damper is generally disc-shaped.

[0040] like Figure 2 As shown, the hub 5 may include an axial extension 51 and a radial extension 52. The axial extension 51 may extend along the axial direction A and the circumferential direction C to form a cylindrical shape, and the radial extension 52 may extend along the radial direction R and the circumferential direction C to form a disc shape or annular shape. The axial extension 51 may be connected to the radially inner side of the radial extension 52; preferably, the two may be integrally formed. As an example, the hub 5 may be used to connect to the crankshaft of an internal combustion engine.

[0041] The spoke assembly 4 can be annular. The spoke assembly 4 is sleeved on the axial extension 51, and the inner circumference of the spoke assembly 4 can be fixedly connected to the radial extension 52 by the inner circumference fastener 6.

[0042] The support washer 3 can be annular and can be fitted onto the axial extension 51. The support washer 3 and the radial extension 52 can be respectively disposed on both sides of the spoke assembly 4. As an example, the inner circumferential fastener 6 can be a rivet or a screw, and the inner circumferential fastener 6 can pass through the radial extension 52, the spoke assembly 4 and the support washer 3, thereby connecting them together.

[0043] like Figures 3 to 5 As shown, the spoke assembly 4 may include multiple spoke modules 41. The spoke modules 41 are generally fan-shaped, and the multiple spoke modules 41 can be arranged in a ring along the circumferential direction C of the spoke spring damper.

[0044] The spoke module 41 may include a center portion 411, an outer ring portion 412, and spoke portions 413. The center portion 411 and the outer ring portion 412 may be arc-shaped, and the spoke portions 413 may extend radially R along the spoke spring damper as a whole. The center portion 411 and the outer ring portion 412 can be connected via the spoke portions 413. More specifically, a center portion 411 and an outer ring portion 412 can be connected via multiple spoke portions 413. The spoke portions 413 may be made of an elastic material, such as a sheet of metal. The spoke portions 413 are elastically deformable, allowing the center portion 411 and the outer ring portion 412 to rotate relative to each other. When torque vibration occurs in the spoke assembly 4, these spoke portions 413 are elastically deformable, allowing the inner periphery (center portion 411) and the outer periphery (outer ring portion 412) of the spoke assembly 4 to rotate relative to each other within a certain range (depending on the magnitude of the torque and the elastic deformation capability of the spoke portions 413), thereby buffering the torque vibration. Here, the spoke module 41 may include multiple integral spoke module sheets, that is, the central part 411, the outer ring part 412 and the spoke part 413 of a spoke module sheet may be integrally formed.

[0045] The center portion 411 may be provided with a center mounting hole 414, and the center portion 411 may be connected to the radial extension portion 52 by passing through the center mounting hole 414 and connecting to the radial extension portion 52 through the inner peripheral fastener 6.

[0046] The outer ring portion 412 may be provided with an outer ring portion mounting hole 415. As an example, the outer peripheral fastener 7 may be a rivet or a screw. By passing the outer peripheral fastener 7 through the outer ring portion mounting hole 415 and connecting it to the cover plate 1, the outer ring portion 412 can be connected to the cover plate 1.

[0047] In the circumferential direction C of the spoke spring damper, the stiffness of multiple spoke modules 41 can be the same. Here, the same stiffness mainly refers to the same stiffness of the spoke section 413.

[0048] The diaphragm spring 2 can be annular, and the diaphragm spring 2 can be sleeved on the axial extension 51. A part of the diaphragm spring 2 is connected to one of the central part 411 and the outer ring part 412, and the other part of the diaphragm spring 2 abuts against the other of the central part 411 and the outer ring part 412, so that when the central part 411 and the outer ring part 412 rotate relative to each other, the diaphragm spring 2 can (directly or indirectly) rub against the other of the central part 411 and the outer ring part 412.

[0049] Furthermore, the cover plate 1 is fixedly connected to the other of the central portion 411 and the outer ring portion 412, and the diaphragm spring 2 indirectly abuts against the other of the central portion 411 and the outer ring portion 412 via the cover plate 1. Thus, when the central portion 411 and the outer ring portion 412 rotate relative to each other, the diaphragm spring 2 can rub against the cover plate 1, and the friction can prevent the outer periphery of the spoke assembly 4 from rotating relative to the inner periphery of the spoke assembly 4.

[0050] It is understandable that when the outer periphery of the diaphragm spring 2 is connected to the outer ring 412, the inner periphery of the diaphragm spring 2 can also rub against the radial extension 52 or the support washer 3.

[0051] like Figure 1 and Figure 2 As shown, in this embodiment, the cover plate 1 is generally annular, and the cover plate 1 can be fixedly connected to the axial side of the outer ring portion 412. For example, there can be two cover plates 1, and the two cover plates 1 can be respectively disposed on the axial sides of the outer ring portion 412. When the outer periphery of the spoke assembly 4 rotates relative to the inner periphery of the spoke assembly 4, the cover plate 1 also rotates with the outer periphery of the spoke assembly 4 relative to the inner periphery of the spoke assembly 4.

[0052] Two diaphragm springs 2 can be provided, with each diaphragm spring 2 positioned on one side of the spoke assembly 4 along its axial direction. The inner circumference of the diaphragm spring 2 can be fixedly connected to the center portion 411. Specifically, the inner circumference of the diaphragm spring 2 can have a through hole, through which an inner circumferential fastener 6 can pass to fix the diaphragm spring 2 to the center portion 411. Along the axial direction A, the diaphragm spring 2 can be located between the cover plate 1 and the spoke assembly 4, with the outer circumference of the diaphragm spring 2 abutting against the cover plate 1. The diaphragm spring 2 is deformed by the cover plate 1 along the axial direction A. When the outer circumference of the spoke assembly 4 rotates relative to the inner circumference of the spoke assembly 4, the cover plate 1 can move relative to the diaphragm spring 2, causing friction between the contact surfaces of the cover plate 1 and the diaphragm spring 2. This friction can hinder the rotation of the outer circumference of the spoke assembly 4 relative to the inner circumference of the spoke assembly 4.

[0053] like Figure 3 and Figure 4 As shown, in the circumferential direction C of the spoke spring damper, multiple spoke modules 41 can contact each other to form a ring. This contact includes the central portion 411 and / or the outer ring portion 412 contacting each other and arranging in a ring along the circumferential direction C. In this embodiment, the central portions 411 of multiple adjacent spoke modules 41 can contact each other to form a ring, and the outer ring portions 412 of multiple adjacent spoke modules 41 can be spaced apart by a certain distance.

[0054] Optionally, the spoke module 41 can be integrally formed or formed by stacking multiple layers (i.e., multiple spoke module sheets) together. The spoke module 41 can be manufactured using a stamping process. Compared to the annular spoke assembly 4, the fan-shaped spoke module 41 is smaller in size, easier to manufacture, and less expensive.

[0055] In one possible implementation, the spoke assembly 4 may include a first spoke module and a second spoke module, which are arranged alternately along the circumferential direction C. The first spoke module and the second spoke module have different stiffnesses. This difference in stiffness mainly refers to the different stiffness of the spoke portion 413 of the first spoke module and the spoke portion 413 of the second spoke module. This allows for flexible combinations of spoke modules with different stiffnesses to create various spoke assemblies 4, depending on actual needs. It is understood that the spoke assembly 4 may include two or more spoke modules with different stiffnesses.

[0056] It is understandable that different stiffnesses of spoke modules can be achieved by constructing spoke modules with different structures or materials, or by stacking different numbers of spoke module sheets along the axial direction in a single spoke module.

[0057] (Second Implementation)

[0058] Figure 6 A spoke spring damper according to a second embodiment of this application is shown. Components that are the same as or similar to those in the spoke spring damper of the first embodiment are labeled with the same reference numerals, and detailed descriptions of these components are omitted.

[0059] The difference between the spoke spring damper of the second embodiment and the spoke spring damper of the first embodiment is that the arrangement of the spoke modules 41 is different, while the structure of the spoke modules 41 of the second embodiment and the spoke modules 41 of the first embodiment can be the same.

[0060] The second embodiment of this application proposes a spoke spring damper, which includes a cover plate 1, a diaphragm spring 2, a support washer 3, a spoke assembly 4, a hub 5, an inner peripheral fastener 6, and an outer peripheral fastener 7.

[0061] On the circumferential C of the spoke spring damper, multiple spoke modules 41 can be spaced apart from each other. The space between adjacent spoke modules 41 can accommodate one or more spoke modules 41, and there can be one (or more) mounting positions for two adjacent spoke modules 41. For example, on the circumferential C of the spoke spring damper, there are mounting positions for 2n (e.g., 6) spoke modules 41, but only n (e.g., 3) spoke modules 41 are installed. In this way, compared to installing spoke modules 41 at all mounting positions (first embodiment), the second embodiment can reduce the rigidity of the spoke assembly 4, and the rigidity of the spoke assembly 4 can be easily adjusted according to actual needs without producing a completely new spoke assembly.

[0062] It is understood that the spacing between circumferentially adjacent spoke modules 41 is not limited to this. In another example, the spoke assembly 4 may contain multiple spoke module sheets that are offset in the circumferential direction C (e.g., less than the size of one spoke module 41) and overlap each other (with occlusion) when viewed axially.

[0063] In summary, the spoke assembly 4 formed by combining multiple spoke modules 41 can adjust the rigidity of the spoke assembly 4 according to actual needs through the installation method of the spoke modules 41. The spoke assembly 4 has good flexibility of use and wide applicability.

[0064] (Third Implementation)

[0065] Figure 7 A spoke spring damper according to a third embodiment of this application is shown. Components that are the same as or similar to those in the spoke spring damper of the first embodiment are labeled with the same reference numerals, and detailed descriptions of these components are omitted.

[0066] like Figure 7 As shown, the third embodiment of this application proposes a spoke spring damper, which includes a cover plate 1, a diaphragm spring 2, a support washer 3, a spoke assembly 4, a hub 5, an inner peripheral fastener 6, and an outer peripheral fastener 7.

[0067] The spoke module 41 of the third embodiment can have the same structure as the spoke module 41 of the first embodiment. Compared with the spoke spring damper of the first embodiment, the hub 5 of the spoke spring damper of the third embodiment can have a larger diameter, thereby increasing the radial spacing of the plurality of central mounting holes 414. In the circumferential direction C of the spoke spring damper, the plurality of spoke modules 41 can be spaced apart from each other. The central portions 411 of adjacent spoke modules 41 can be spaced apart from each other, and the outer ring portions 412 of adjacent spoke modules 41 can be spaced apart from each other. Depending on actual needs, identical spoke modules 41 can be combined to form a spoke assembly 4 with a larger diameter, thereby allowing the spoke assembly 4 to obtain a larger moment of inertia at the same rotational speed.

[0068] In summary, the spoke assembly 4 formed by combining multiple spoke modules 41 can adjust the moment of inertia of the spoke assembly 4 according to actual needs by adjusting the installation position of the spoke modules 41. The spoke assembly 4 has good flexibility in use and wide applicability.

In addition, the following description is provided.

[0070] (1) In the above embodiment, the diaphragm spring 2 is connected to the inner periphery of the spoke assembly 4, and the cover plate 1 is connected to the outer periphery of the spoke assembly 4. However, this application is not limited to this. In other possible embodiments, the diaphragm spring may be connected to the outer periphery of the spoke assembly, and the cover plate may be connected to the inner periphery of the spoke assembly. As long as the diaphragm spring can be fixed (directly or indirectly) to one of the inner periphery and the outer periphery of the spoke assembly, and abut against the other (directly or indirectly), frictional damping can be provided when the inner periphery and the outer periphery of the spoke assembly rotate relative to each other.

[0071] (2) In the above embodiment, cover plates 1 and diaphragm springs 2 are provided on both axial sides of the spoke assembly 4. However, this application is not limited to this. In other possible embodiments, cover plates 1 and diaphragm springs 2 may be provided only on one axial side of the spoke assembly 4.

[0072] It should be understood that at least some aspects or features of the above-described implementation methods, embodiments, or examples can be appropriately combined.
