Description

Technical Field

[0001] This utility model belongs to the field of clutch pressure plate technology, specifically relating to a clutch pressure plate made of high-temperature resistant ceramic composite material. Background Technology

[0002] The clutch pressure plate is an important structure on the clutch. During vehicle operation, it must ensure that the clutch driven plate and flywheel are in close contact. Its main responsibility is to smoothly transmit the engine's power to the transmission and allow the driver to interrupt this power transmission when shifting gears or stopping.

[0003] Problems with existing technology:

[0004] Currently, existing clutch pressure plates generate a lot of heat due to frequent friction during operation. However, the heat dissipation performance of existing pressure plates is poor, which can easily lead to excessively high pressure plate temperatures. This can cause accelerated wear on the pressure plate. In addition, most existing pressure plates are made of cast iron, which can easily lead to thermal degradation when the friction surface temperature is too high. This can affect the normal operation of the clutch, reduce its service life, and even threaten the safety of vehicle operation. Utility Model Content

[0005] The purpose of this invention is to provide a clutch pressure plate made of high-temperature resistant ceramic composite material. By improving the material of the clutch plate, it can be made to have the characteristics of high temperature resistance, wear resistance and high strength, thereby solving the problems of pressure plate deformation and poor heat dissipation.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] A clutch pressure plate made of high-temperature resistant ceramic composite material includes a clutch cover, wherein a diaphragm spring is abutted inside the clutch cover.

[0008] The bottom of the diaphragm spring pushes the pressure plate assembly to abut against the clutch disc, and the clutch disc is fixedly installed with the flywheel;

[0009] The pressure plate assembly includes a pressure plate body that abuts against the clutch disc. A support frame is fixedly installed on the top of the pressure plate body. The top of the support frame is engaged with a diaphragm spring through a slot. The pressure plate body is fixedly installed to the clutch cover through a connecting assembly.

[0010] The top of the pressure plate body is provided with multiple heat dissipation slots, and the multiple heat dissipation slots include an inlet section, an outlet section and a negative pressure section, and the negative pressure section is connected between the inlet section and the outlet section.

[0011] The connecting components are integrally formed with the pressure plate body, and three sets of the connecting components are arranged around the top of the pressure plate body.

[0012] The connecting assembly includes a fixed base that is fixedly installed on the top of the pressure plate body, a spring plate that is fixedly installed on the top of the fixed base, and a connecting pin that is provided inside the other end of the spring plate.

[0013] The connecting pin is used to pass through the clutch cover and the spring plate, so that the top of the connecting pin abuts against the bottom of the clutch cover.

[0014] The pressure plate body includes a base layer, an internal reinforcing layer, and a surface coating on the bottom of the base layer.

[0015] The base layer is a silicon carbide matrix, the reinforcing layer is a carbon fiber braided layer, and the surface coating is a metal-ceramic coating.

[0016] The technical effects achieved by this utility model are as follows:

[0017] This invention utilizes a support frame installed on the top of the pressure plate body. Through the linkage between the slot on the top of the support frame and the connecting components, the pressure plate assembly can be stably installed with the clutch cover. Simultaneously, the support frame ensures a certain gap between the pressure plate assembly and the clutch cover, and the heat dissipation grooves effectively improve the heat dissipation of the pressure plate assembly.

[0018] This invention replaces the cast iron pressure plate body with a composite material made of silicon carbide matrix and carbon fiber braided layer, giving the pressure plate assembly better high temperature resistance and wear resistance. It also further improves the impact resistance of the pressure plate assembly. In addition, the surface coating sprayed on the friction surface of the pressure plate assembly can further reduce the friction coefficient of the pressure plate assembly, thereby improving the performance of the pressure plate assembly.

[0025] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0026] like Figure 1-4 As shown, a clutch pressure plate made of high-temperature resistant ceramic composite material includes a clutch cover 1, and a diaphragm spring 2 is abutted inside the clutch cover 1.

[0027] The bottom of the diaphragm spring 2 pushes the pressure plate assembly 3 to abut against the clutch plate 4, and the clutch plate 4 is fixedly installed with the flywheel 5;

[0028] The pressure plate assembly 3 includes a pressure plate body 31 that abuts against the clutch plate 4. A support frame 33 is fixedly installed on the top of the pressure plate body 31. The top of the support frame 33 is engaged with the diaphragm spring 2 through a slot 34. The pressure plate body 31 is fixedly installed with the clutch cover 1 through a connecting assembly 32.

[0029] See attached document Figure 1 , Figure 2 and Figure 3 In this embodiment, the top of the pressure plate body 31 is provided with a plurality of heat dissipation grooves 35, and the plurality of heat dissipation grooves 35 include an inlet section, an outlet section and a negative pressure section, and the negative pressure section is connected between the inlet section and the outlet section.

[0030] In the above embodiment, since the inlet section of the heat dissipation groove 35 abuts against the support frame 33, and the support frame 33 has a certain thermal conductivity, the heat can be absorbed by the negative pressure section set between the inlet section and the outlet section of the heat dissipation groove 35 and discharged through the heat dissipation groove 35.

[0031] Furthermore, due to the arrangement of the support frame 33, there is a certain gap between the diaphragm spring 2 and the pressure plate assembly 3, so that the heat of the pressure plate assembly 3 can be quickly discharged.

[0032] It should be noted that the connecting component 32 is integrally formed with the pressure plate body 31, and three sets of connecting components 32 are arranged around the top of the pressure plate body 31. The connecting component 32 includes a fixing seat 321 fixedly installed on the top of the pressure plate body 31, and a spring 322 is fixedly installed on the top of the fixing seat 321. At the same time, a connecting pin 323 is provided inside the other end of the spring 322. Therefore, under the elastic action of the connecting pin 323 and in linkage with the diaphragm spring 2, the movement of the pressure plate assembly 3 is made more stable.

[0033] According to the above structure, the connecting pin 323 can pass through the clutch cover 1 and the spring 322, so that the top of the connecting pin 323 abuts against the bottom of the clutch cover 1, thereby realizing the convenient installation of the diaphragm spring 2 and the pressure plate assembly 3.

[0034] See attached document Figure 1 , Figure 3 and Figure 4 In this embodiment, the pressure plate body 31 includes a base layer 311, an internal reinforcing layer 312 is provided inside the base layer 311, and a surface coating 313 is provided at the bottom of the base layer 311.

[0035] In the above embodiment, the base layer 311 is a silicon carbide substrate, the reinforcing layer 312 is a carbon fiber braided layer, and the surface coating 313 is a metal ceramic coating. The reinforcing layer 312 can enhance the structural strength of the pressure plate assembly 3, thereby improving the impact resistance of the pressure plate assembly 3. Under the action of the base layer 311 and the surface coating 313, the pressure plate assembly 3 has high temperature resistance and wear resistance.

[0036] The working principle of this utility model is as follows: the pressure plate assembly 3 and the clutch cover 1 can be installed by using the connecting component 32. When the pressure plate assembly 3 is in use, the heat dissipation performance of the pressure plate assembly 3 can be improved by the cooperation of the support frame 33 and the heat dissipation groove 35. By improving the material of the pressure plate body 31, the high temperature resistance, wear resistance and impact resistance of the pressure plate assembly 3 can be improved.

[0037] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
