Abstract
Description
Technical Field
[0001] This application belongs to the technical field of clutch components, and more specifically, relates to a pre-damped inverted universal driven plate assembly and clutch for both large and small horsepower applications. Background Technology
[0002] The clutch is a crucial component of an automotive transmission system, and the driven plate, as its core part, together affect the vehicle's power transmission, driving smoothness, and safety. Clutches are classified into push clutches and pull clutches. A pull clutch typically consists of a release ring, diaphragm spring, pressure plate, driven plate, and flywheel. When the release ring is not subjected to external force, it moves towards the flywheel under the action of the diaphragm spring, and the pressure plate presses the driven plate against the flywheel, thus achieving power transmission.
[0003] When a pull clutch engages, the release ring moves closer to the flywheel. This is especially true when the friction plates on the outer ring of the driven plate wear thinner, causing the release ring to move even closer to the flywheel. This makes it easier for the release ring to interfere with the driven plate. Therefore, sufficient space needs to be reserved in the design to avoid interference problems.
[0004] In modern vehicles of varying horsepower, the driven disc of the clutch typically features a pre-damper in addition to the main shock absorber, to further reduce power impact and ensure smooth operation of the transmission system. However, current pre-dampers are quite thick, which exacerbates interference issues when the driven disc with the pre-damper is used in a pull-type clutch, necessitating a solution. Utility Model Content
[0005] In view of this, the present application provides a pre-damping inverted universal driven plate assembly and clutch for both large and small horsepower, in order to solve the technical problem in the prior art that the release ring is prone to interference with the pre-damping device.
[0006] To achieve the above objectives, the technical solution adopted in this application is as follows:
[0007] On the one hand, a pre-damped inverted universal driven disc assembly for both large and small horsepower is provided, including:
[0008] The friction disc has its central area offset away from the flywheel.

It should be understood that the specific embodiments described herein are merely illustrative and are not intended to limit the scope of this application.

They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.
[0032] Please refer to the following: Figures 1 to 3 The following describes the pre-damped inverted universal driven disc assembly for both large and small horsepower provided in the embodiments of this application. A pre-damped inverted universal driven disc assembly for both large and small horsepower includes:
[0033] The friction disc has its central area offset away from the flywheel.
[0034] The pre-damper is located on the side of the friction disc facing the flywheel in the central area and is suitable for circumferential damping.
[0035] The inner hub is located at the center of the friction disc via a pre-damping device.
[0036] Compared with the prior art, the pre-damping inverted universal driven disc assembly for both large and small horsepower in this application embodiment installs the pre-damper on the side of the friction disc's central area facing the flywheel, avoiding interference between the pre-damper and the release ring; at the same time, offsetting the central area of the friction disc away from the flywheel ensures sufficient distance between the pre-damper and the flywheel, preventing interference between them; moreover, the space on both sides of the central area of the friction disc can be reasonably allocated by controlling the offset amount, improving the rationality of the design.
[0037] In this embodiment, the overall structure of the friction disc can refer to the prior art, the only difference being that the central region is offset away from the flywheel. This offset of the central region of the friction disc away from the flywheel can be understood as the central surface of the central region of the friction disc being further away from the flywheel than the central surface of the outer ring region of the friction disc.
[0038] The inner disc hub is mounted at the center of the friction disc via a pre-damper. The structure of the pre-damper and the inner disc hub can refer to existing technology. The interior of the inner disc hub typically has splined holes for connecting a splined shaft. The installation position of the pre-damper differs from existing technology; in this embodiment, it is installed on the side of the friction disc's central region facing the flywheel.
[0039] Please see Figures 1 to 3 As a specific embodiment of the pre-damping inverted universal driven disc assembly for various horsepower ratings provided in this application, the friction disc includes:
[0040] The main plate body has a central area that is concave away from the flywheel.
[0041] Two clamping discs are located on either side of the central area of the main disc body and are circumferentially rotatable relative to the main disc body;
[0042] The shock-absorbing spring is located between the two clamping plates and is arranged around the circumference of the friction disc. One end of the spring abuts against the two clamping plates, and the other end abuts against the main disc body.
[0043] In this embodiment, by recessing the central area of the main disc body away from the flywheel, the central area of the friction disc is offset away from the flywheel.
[0044] In practical implementation, two clamping discs are located on either side of the main disc body and are fixed together by pins. The two clamping discs can rotate circumferentially relative to the main disc body at a certain angle. A damping spring is installed between the two clamping discs, with one end abutting against the two clamping discs and the other end abutting against the main disc body, thus buffering the circumferential impact force between the clamping discs and the main disc body. More specifically, the two clamping discs have corresponding notches, and the main disc body also has notches corresponding to the notches on the two clamping discs. The damping springs are installed in three corresponding notches. The friction disc may have multiple damping springs distributed circumferentially.
[0045] Please see Figure 1 and Figure 2 As a specific embodiment of the pre-damped inverted universal driven disc assembly for both large and small horsepower provided in this application, the pre-damper is located on the outside of the clamp near the flywheel.
[0046] In practice, the pre-damper is fixed to the outside of the clamp near the flywheel, and
[0047] Please see Figures 1 to 3 As a specific embodiment of the pre-damping inverted universal driven disc assembly for both large and small horsepower provided in this application, the inner disc hub is installed at the center of the two clamping discs and can rotate circumferentially relative to the clamping discs.
[0048] In practice, the two clamping plates have a central opening, and the inner hub is installed at the center of the two clamping plates and can rotate circumferentially relative to the clamping plates at a certain angle.
[0049] Please see Figures 1 to 3 This application embodiment also provides a clutch, the clutch including: a pre-damped inverted universal driven plate assembly of different horsepower as described above.
[0050] Compared with the prior art, the clutch in the embodiments of this application can adopt a push clutch or a pull clutch structure. By adopting the pre-damped inverted universal driven plate assembly of any of the above, similar functions and effects are achieved, which will not be described in detail here.
[0051] Please see Figure 1 and Figure 2 As one specific embodiment of the clutch provided in this application, the clutch is a pull clutch.
[0052] For pull clutches, when the friction plates on the outer ring of the friction disc wear down, the release ring at the center of the diaphragm spring will move closer to the center of the friction disc. (See also...) Figure 1 and Figure 2 In contrast, interference with the driven plate is more likely. In this embodiment, the above-mentioned pre-damped inverted universal driven plate assembly for both large and small horsepower is applied to the pull clutch, which can better solve the interference problem.
[0053] Please see Figure 1 and Figure 2 As one specific embodiment of the clutch provided in this application, the clutch includes a release ring, the inner diameter of which is larger than the outer diameter of the end of the inner disc hub facing away from the flywheel.
[0054] In this embodiment, the end of the inner hub facing away from the flywheel is smaller and can enter the interior of the separation ring, allowing the separation ring to get closer to the inner hub without interference.
[0055] In practice, the separation ring is installed at the center notch of the diaphragm spring to pull the middle part of the diaphragm spring away from the flywheel.
[0056] Please see Figure 1 and Figure 2 As one specific embodiment of the clutch provided in this application, the clutch includes a flywheel, and a recessed area for avoiding the pre-damping device is formed in the middle of the flywheel.
[0057] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
