Description

Technical Field

[0001] The utility model relates to the technical field of clutch accessories, and particularly relates to a multi-disc clutch friction plate assembly. Background Art

[0002] A clutch is a mechanism that transmits power by axially pressing and releasing two flat clutch friction plates. The clutch friction plate assembly is mainly composed of a driven plate, a torsional damper, a friction plate, rivets and other structures.

[0003] In the existing clutch friction plate assembly, the friction plate is mainly fixed on the driven plate by riveting. It is necessary to drill holes in the friction plate and the driven plate first, and then press and fix the two with rivets. However, the friction plate is inevitably worn during use, which easily causes the end of the rivet to be worn off and the friction plate to fall off. Summary of the Utility Model

[0004] Based on this, the purpose of the utility model is to provide a multi-disc clutch friction plate assembly to solve the technical problems mentioned in the above background art.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: A multi-disc clutch friction plate assembly includes a driven plate. Two fixing plates are sleeved on the outer circle of the driven plate. Coarse surfaces are arranged on both sides of the fixing plates, and a friction plate is fixed on one side of the coarse surface through an adhesive layer. A fastening hole is formed on one side of the friction plate, and an adhesive block is arranged inside the fastening hole.

[0006] By adopting the above technical scheme, the friction plate is connected to the fixing plate through an adhesive and the coarse surface. The arrangement of the coarse surface increases the contact area between the adhesive and the fixing plate, and the rough surface of the friction plate itself can also increase the contact area with the adhesive, so that the friction plate is stably connected to the fixing plate. The adhesive will enter the fastening hole. After the adhesive cures, an adhesive layer and an adhesive block are formed. Both the adhesive block and the fastening hole are frustum-shaped, which can hold the friction plate and further prevent the friction plate from falling off. Even if the adhesive block is worn, it can still support the friction plate.

[0007] Further, both the fastening hole and the adhesive block are frustum-shaped, and the adhesive block is fixedly connected to the adhesive layer by an integral molding method.

[0008] By adopting the above technical scheme, the adhesive will enter the fastening hole. After the adhesive cures, an adhesive block integrated with the adhesive layer is formed. Both the adhesive block and the fastening hole are frustum-shaped, which can hold the friction plate and further prevent the friction plate from falling off. Even if the adhesive block is worn, it can still support the friction plate.

[0009] Further, the adhesive blocks and fastening holes are grouped in pairs, divided into multiple groups, and the multiple groups of adhesive blocks and fastening holes are distributed in an annular array.

[0010] By adopting the above technical solution, the contact area with the friction plate is increased by increasing the number of adhesive blocks, and the friction plate can be effectively pulled by the adhesive blocks to achieve the effect of auxiliary support, effectively avoiding the falling off of the friction plate.

[0011] Further, a plurality of fixing holes are provided on both sides of the driven disk and the two fixing plates, and a plurality of rivets are respectively connected inside the plurality of fixing holes.

[0012] By adopting the above technical solution, after the friction plate is fixed, the staff sleeved the fixing plate on the driven disk, and then the staff passed the rivet through the fixing hole and removed the core of the rivet, so as to fix the fixing plate and the driven disk.

[0013] Further, the cross-section of the fixing plate is in a "Y" shape, and the two fixing plates are mirror-symmetrically arranged.

[0014] By adopting the above technical solution, the two fixing plates have a split structure to facilitate the connection between the fixing plate and the driven disk, so as to facilitate the subsequent insertion of rivets to fix the structure.

[0015] Further, a plurality of friction plates, adhesive layers and roughened surfaces are provided, and the plurality of friction plates, adhesive layers and roughened surfaces are distributed in an annular array.

[0016] By adopting the above technical solution, the roughened surface increases the contact area between the adhesive layer and the fixing plate, and the rough surface of the friction plate itself can also increase the contact area with the adhesive layer, so that the friction plate is stably connected to the fixing plate.

[0017] Further, the first reinforcing ribs and the second reinforcing ribs are fixed on both sides of the fixing plate.

[0018] By adopting the above technical solution, the structural strength of the fixing plate is increased by the arrangement of the first reinforcing ribs and the second reinforcing ribs, avoiding the occurrence of bending deformation of the fixing plate.

[0019] Further, a plurality of the first reinforcing ribs and the second reinforcing ribs are provided, and the plurality of the first reinforcing ribs and the second reinforcing ribs are distributed in an annular array.

[0020] By adopting the above technical solution, the support area of the fixing plate is increased by increasing the number of the first reinforcing ribs and the second reinforcing ribs, so as to further improve the structural strength of the fixing plate.

[0021] In summary, the main beneficial effects of the present utility model are as follows:

[0022] 1. In the present utility model, through the settings of the fixing plate, adhesive layer, adhesive block, roughened surface, and fastening holes, the friction plate is connected to the fixing plate through an adhesive and the roughened surface. The setting of the roughened surface increases the contact area between the adhesive and the fixing plate, and the rough surface of the friction plate itself can also increase the contact area with the adhesive, so that the friction plate is stably connected to the fixing plate. Moreover, the adhesive will enter the fastening holes. After the adhesive cures, an adhesive layer and adhesive blocks are formed. Both the adhesive blocks and the fastening holes are frustum-shaped, which can hold the friction plate and further prevent the friction plate from falling off. Even if the adhesive blocks are worn, they can still provide auxiliary support for the friction plate; effectively avoiding the phenomenon that the rivets are worn flat and the friction plate falls off.

[0023] 2. In the present utility model, through the settings of the first reinforcing rib and the second reinforcing rib, the structural strength of the fixing plate is increased by the settings of the first reinforcing rib and the second reinforcing rib, avoiding the phenomenon of the fixing plate bending and deforming; improving the structural strength and extending the service life.

The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present utility model and should not be construed as limiting the present utility model.

[0030] Next, the embodiments of the present utility model will be described according to the overall structure of the present utility model.

[0031] Embodiment 1:

[0032] A multi-disc clutch friction plate assembly, as Figures 1-4As shown in the figure, it includes a driven plate 1. Two fixing plates 2 are sleeved on the outer ring of the driven plate 1. The cross-section of the fixing plate 2 is in a "Y" shape. The two fixing plates 2 are arranged mirror-symmetrically. The staff sleeved the fixing plate 2 on the driven plate 1 to complete the connection; both sides of the fixing plate 2 are provided with roughened surfaces 9. One side of the roughened surface 9 is fixed with a friction plate 6 through an adhesive layer 7. There are multiple friction plates 6, adhesive layers 7 and roughened surfaces 9. The multiple friction plates 6, adhesive layers 7 and roughened surfaces 9 are all distributed in an annular array. After the binder cures, an adhesive layer 7 and an adhesive block 8 are formed. The setting of the roughened surface 9 increases the contact area between the adhesive layer 7 and the fixing plate 2, and the rough surface of the friction plate 6 itself can also increase the contact area with the adhesive layer 7, so that the friction plate 6 is stably connected to the fixing plate 2; a fastening hole 10 is opened on one side of the friction plate 6. An adhesive block 8 is arranged inside the fastening hole 10. Both the fastening hole 10 and the adhesive block 8 are frustum-shaped. The adhesive block 8 is fixedly connected to the adhesive layer 7 by an integral molding method. The adhesive block 8 and the fastening hole 10 are in a group, and there are multiple groups in total. The multiple groups of adhesive blocks 8 and fastening holes 10 are all distributed in an annular array. The binder will enter the fastening hole 10. After the binder cures, an adhesive block 8 integrated with the adhesive layer 7 is formed. Both the adhesive block 8 and the fastening hole 10 are frustum-shaped, which can hold the friction plate 6 and further prevent the friction plate 6 from falling off. Even if the adhesive block 8 is worn, it can still assist in supporting the friction plate 6.

[0033] Refer to Figure 2 and Figure 3 , in the above embodiment, a plurality of fixing holes 11 are respectively opened on both sides of the driven plate 1 and the two fixing plates 2. A plurality of rivets 3 are respectively connected inside the plurality of fixing holes 11. The staff sleeved the fixing plate 2 on the driven plate 1, and then the staff passed the rivets 3 through the fixing holes 11 and removed the cores of the rivets 3, so as to fix the fixing plate 2 and the driven plate 1.

[0034] Embodiment Two:

[0035] On the basis of the above Embodiment One, in order to increase the structural strength of the fixing plate 2, the following settings are now made.

[0036] Refer to Figures 1-4 , in the above embodiment, a first reinforcing rib 4 and a second reinforcing rib 5 are respectively fixed on both sides of the fixing plate 2. There are multiple first reinforcing ribs 4 and second reinforcing ribs 5. The multiple first reinforcing ribs 4 and second reinforcing ribs 5 are all distributed in an annular array. By setting the first reinforcing rib 4 and the second reinforcing rib 5, the structural strength of the fixing plate 2 is increased, and the phenomenon of the fixing plate 2 bending and deforming is avoided.

[0037] The implementation principle of the present utility model is as follows: First, during production, the staff grinds the surface of the fixed plate 2 to form multiple roughened surfaces 9. Then, the staff uses an adhesive to bond the friction plate 6 to the fixed plate 2. After the adhesive cures, an adhesive layer 7 and adhesive blocks 8 are formed. The setting of the roughened surfaces 9 increases the contact area between the adhesive layer 7 and the fixed plate 2, and the rough surface of the friction plate 6 itself can also increase the contact area with the adhesive layer 7, thereby stably connecting the friction plate 6 to the fixed plate 2. Moreover, the adhesive will enter the fastening holes 10, and after curing, adhesive blocks 8 integrated with the adhesive layer 7 are formed. Both the adhesive blocks 8 and the fastening holes 10 are frustum-shaped, which can hold the friction plate 6 and further prevent the friction plate 6 from falling off. Even if the adhesive blocks 8 are worn, they can still provide auxiliary support for the friction plate 6;

[0038] After fixing the friction plate 6, the staff sleeved the fixed plate 2 on the driven disk 1. Then, the staff passed the rivet 3 through the fixing hole 11 and removed the core of the rivet 3, thereby fixing the fixed plate 2 to the driven disk 1. At the same time, the structural strength of the fixed plate 2 is increased through the settings of the first reinforcing rib 4 and the second reinforcing rib 5, avoiding the occurrence of bending and deformation of the fixed plate 2. During use, the driving device in the clutch makes the two clutch friction plate assemblies fit together, thereby being able to transmit power, and the separation of the two clutch friction plate assemblies ends the power transmission.
