Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of waveform sheets for driven disk assemblies, and particularly to waveform sheets for driven disk assemblies. Background Technology
[0002] The driven plate assembly is the core component of the automotive clutch, and the wave plate, as a key elastic element in the driven plate assembly, mainly plays the role of buffering and shock absorption, compensating for wear, and transmitting torque.
[0003] To this end, patent CN219712125U discloses a wave plate for a driven disc assembly, including an annular wave plate body. The annular wave plate body is provided with several sets of first mounting holes and several L-shaped notches spaced apart. A first bending portion is provided on the left side of the L-shaped notch, and a second bending portion, a third bending portion, a fourth bending portion, and a fifth bending portion are provided on the right side. The first bending portion, the second bending portion, the third bending portion, the fourth bending portion, and the fifth bending portion divide the annular wave plate body into four damping portions. The outer ring of the annular wave plate body is directly bent through several bending portions to form an integral wave plate, eliminating the need for piece-by-piece installation. The outer side is provided with L-shaped notches and first square notches to prevent tearing, and the inner ring is provided with several second square notches to prevent tearing. The second square notches are also used for the adaptation of the damping spring in the driven disc. After installation, the damping spring is located in the second square notch.
[0004] The existing technical solutions described above have the following drawbacks: Although the outer ring of the annular wave sheet is directly bent to form an integral wave sheet through several bending parts, eliminating the need for individual installation, and the outer side is provided with an L-shaped notch and a first square notch to prevent tearing, and the inner ring is provided with several second square notches to prevent tearing, and the second square notches are also used for the adaptation of the damping spring in the driven plate, and the damping spring is located in the second square notch after installation, the existing wave sheet used in the driven plate assembly has certain limitations in use. Due to the frequent engagement and disengagement of the clutch during vehicle operation, the wave sheet is subjected to periodic axial pressure and torque for a long time, which can easily lead to elastic fatigue failure and a decrease in buffering performance.

[0057] Through the auxiliary cooperation between the heat dissipation hole 31 and the heat sink 32, heat can be transferred to the heat sink 32 through the thermally conductive silicone layer 33.
[0058] Working principle: When the operator uses the waveform sheet body 11;
[0059] First, when heat is generated during the operation of the waveform sheet body 11, a heat sink 32 is fixedly connected to the back of the waveform sheet body 11, and the heat can be transferred to the heat sink 32 through the thermally conductive silicone layer 33.
[0060] Next, a heat dissipation hole 31 is provided in the middle region of the waveform sheet body 11, which can accelerate heat dissipation through the spiral guide groove when the air flows.
[0061] This step can prevent the waveform body 11 from overheating during use, which would cause the waveform performance to degrade.
