Description

Technical Field

[0001] The utility model relates to the technical field of diaphragm springs, and particularly relates to a diaphragm spring with high heat dissipation performance. Background Art

[0002] The diaphragm spring is a key part on the automotive diaphragm clutch, and plays the role of pressing the pressure plate and separating the lever.

[0003] During the use of the diaphragm spring, a large amount of heat will be generated due to reasons such as frictional heat generation and internal energy conversion. The traditional diaphragm spring usually only opens several heat dissipation holes on its surface for heat dissipation, but the heat dissipation capacity of these heat dissipation holes is often limited. Especially under high-load and high-frequency working conditions, the speed of dissipating heat may not be able to keep up with the speed of heat generation, resulting in the accumulation of heat inside the diaphragm spring, thus leading to an increase in temperature. High temperature is likely to reduce the stiffness of the diaphragm spring, increase stress relaxation, and even cause material degradation, thereby affecting the performance and service life of the clutch. Content of the Utility Model

[0004] The purpose of the utility model is to provide a diaphragm spring with high heat dissipation performance to solve the above problems existing in the prior art.

[0005] The technical solution for the utility model to solve the above technical problems is as follows:

[0006] A diaphragm spring with high heat dissipation performance includes a diaphragm spring body. On the surface of the diaphragm spring body, centered on the central hole of the diaphragm spring body, a plurality of radial grooves are arrayed. And at one end of each radial groove far away from the central hole, it is communicated with the stress hole of the diaphragm spring body. A heat conduction column is embedded in the radial groove. On both side surfaces of the diaphragm spring body and between adjacent two of the radial grooves, centered on the central hole, multiple circles of heat dissipation blocks are circumferentially arrayed and embedded. Both ends of the heat dissipation block are connected with the corresponding heat conduction column, and heat dissipation holes are opened on the heat dissipation blocks.

[0007] The beneficial effect of the utility model is that when heat is generated in the diaphragm spring body, the heat can be transferred through the heat conduction column, so that the heat can quickly transfer from the center to the outside, avoiding the accumulation of heat inside. Through the connected heat dissipation blocks, the heat in the heat conduction column can be quickly extracted, and then through the heat dissipation holes opened on the heat dissipation blocks, the heat is dissipated through the way of air convection; through the above method, the heat conduction efficiency is improved, the residence time of heat inside the diaphragm spring body is reduced, and the accumulation of heat at the center of the diaphragm spring body is avoided under high-load and high-frequency working conditions.

[0008] On the basis of the above technical solution, the utility model can also be improved as follows.

[0009] Further, heat dissipation holes are also formed in several of the heat conduction columns.

[0010] Further, the heat conduction performance of the heat dissipation block far from the central hole is better than that of the heat dissipation block close to the central hole.

[0011] Further, a protective sleeve is installed at the central hole.

[0012] Further, reinforcing rib strips are fixedly installed on both side surfaces of the diaphragm spring body, between the protective sleeve and the heat dissipation block, and between adjacent circles of the heat dissipation blocks.

[0013] Further, reinforcing rib strips are also fixedly installed on both side surfaces of the diaphragm spring body outside the stress holes.

[0014] Further, a zinc yellow antirust paint layer is sprayed on the outer surface of the diaphragm spring body. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Figure 1 It is a schematic diagram of the overall structure of the present invention.

[0016] In the drawings, the list of components represented by each reference numeral is as follows:

[0017] 1. Diaphragm spring body; 2. Radial groove; 3. Heat conduction column; 4. Stress hole; 5. Heat dissipation block, 6. Heat dissipation hole, 7. Central hole, 8. Protective sleeve, 9. Reinforcing rib strip. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The principles and features of the present invention will be described below with reference to the drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0019] As Figure 1 shown, Embodiment 1 of the present invention is a diaphragm spring with high heat dissipation performance, which includes a diaphragm spring body 1. The surface of the diaphragm spring body 1 is centered on the central hole 7 of the diaphragm spring body 1, and a plurality of radial grooves 2 are arranged in an array. One end of each radial groove 2 far from the central hole 7 communicates with the stress hole 4 of the diaphragm spring body 1. A heat conduction column 3 is embedded in the radial groove 2. On both side surfaces of the diaphragm spring body 1 and between adjacent two radial grooves 2, a plurality of circles of heat dissipation blocks 5 are embedded in a circumferential array with the central hole 7 as the center. Both ends of the heat dissipation block 5 are connected to the corresponding heat conduction column 3, and heat dissipation holes 6 are formed in the heat dissipation block 5.

[0020] When the diaphragm spring body 1 generates heat, the heat can be transferred through the heat conduction columns 3, enabling the heat to quickly transfer from the center to the outside, avoiding heat accumulation inside. Through the connected heat dissipation block 5, the heat in the heat conduction columns 3 can be quickly extracted, and then through the heat dissipation holes 6 opened on the heat dissipation block 5, the heat is dissipated through air convection; in this way, the heat conduction efficiency is improved, the residence time of heat inside the diaphragm spring body is reduced, and heat accumulation at the center of the diaphragm spring body 1 is avoided under high-load and high-frequency working conditions.

[0021] In Embodiment 2 of the present utility model, a diaphragm spring with high heat dissipation performance, on the basis of Embodiment 1, heat dissipation holes 6 are also provided on several heat conduction columns 3.

[0022] By providing heat dissipation holes 6 on the heat conduction columns 3, when the heat conduction columns 3 transfer heat, part of the heat can be dissipated by themselves, improving the heat dissipation efficiency.

[0023] In Embodiment 3 of the present utility model, a diaphragm spring with high heat dissipation performance, on the basis of Embodiment 1 or 2, the heat conduction performance of the heat dissipation block 5 far from the central hole 7 is better than that of the heat dissipation block 5 close to the central hole 7.

[0024] The material of the second heat dissipation block 5 has better heat conduction performance and heat dissipation performance than the material of the first heat dissipation block 4. Through such a design, when heat is conducted from the center point of the diaphragm spring body to the outside, it is first absorbed and dissipated partly by the first heat dissipation block 4, and the remaining heat continues to be conducted outward to the second heat dissipation block 5. Since the heat dissipation performance and heat conduction performance of the second heat dissipation block 5 are stronger, it can more effectively handle these remaining heats, thus avoiding excessive heat accumulation in a certain area; at the same time, the material of the second heat dissipation block 5 can be made of red copper, while the first heat dissipation block 4 can be made of copper alloy

[0025] In Embodiment 4 of the present utility model, a diaphragm spring with high heat dissipation performance, on the basis of any one of Embodiments 1 to 3, a protective sleeve 8 is installed at the central hole 7.

[0026] During the working process of the diaphragm spring body 1, the central hole 7 rubs against other components, resulting in wear. Installing the protective sleeve 8 can effectively reduce this friction, thereby extending the service life of the diaphragm spring body 1.

[0027] In Embodiment 5 of the present utility model, a diaphragm spring with high heat dissipation performance, on the basis of Embodiment 4, reinforcing ribs 9 are fixedly installed on both side surfaces of the diaphragm spring body 1 and between the protective sleeve 8 and the heat dissipation block 5 and between adjacent heat dissipation blocks 5.

[0028] The reinforcing rib 9 can significantly improve the rigidity of the diaphragm spring body 1 and its surrounding components. This helps to prevent deformation and vibration generated under high-speed rotation or high-load conditions, ensuring the stable operation of the clutch.

[0029] Embodiment 6 of the present utility model is a diaphragm spring with high heat dissipation. On the basis of any one of Embodiments 1 to 5, reinforcing ribs 9 are also fixedly installed on both side surfaces of the diaphragm spring body 1 and outside the stress holes 4.

[0030] During the operation of the diaphragm spring body 1, certain stresses and loads will be generated. The reinforcing rib 9 can effectively disperse and bear these stresses and loads, reduce the phenomenon of stress concentration, and lower the risk of damage caused by excessive stress.

[0031] Embodiment 7 of the present utility model is a diaphragm spring with high heat dissipation. On the basis of any one of Embodiments 1 to 6, a zinc yellow antirust paint layer is sprayed on the outer surface of the diaphragm spring body 1.

[0032] The zinc yellow antirust paint layer can form a dense protective film on the surface of the diaphragm spring body 1, effectively isolating the direct contact between air, moisture and other corrosive media and the base material, thereby preventing oxidation corrosion on the surface of the spring.

[0033] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
