Description

Technical Field

[0001] This utility model relates to the field of clutch pressure plate technology, specifically a clutch pressure plate with good heat dissipation. Background Technology

[0002] The clutch pressure plate is an important component used for power transmission in a clutch. Together with the engine flywheel and friction plates, the pressure plate forms a friction system. When the clutch engages, the diaphragm spring pushes the pressure plate, causing it to contact the friction plates. Through relative sliding friction, the clutch gradually locks up and completes the engagement. Due to the frequent gear shifting of the clutch, the friction system generates a lot of heat. The difference in linear velocity between the inner and outer diameters of the pressure plate leads to uneven heat distribution, causing thermal deformation of the pressure plate. This results in a reduction in the actual contact area between the pressure plate and the friction plates, a decrease in torque transmission capacity, and even permanent deformation, cracking, and burning of the pressure plate.

[0003] Existing clutch pressure plates suffer from slippage when the clutch pedal is released and they engage with the clutch discs, reducing engine power output efficiency. Furthermore, existing clutch pressure plates have poor heat dissipation and low strength. Therefore, designing a clutch pressure plate with improved heat dissipation is essential. Utility Model Content

[0004] The purpose of this invention is to provide a clutch pressure plate with good heat dissipation, which avoids the problem of slippage when the clutch pedal is released and contact with the clutch disc. It also has a heat dissipation effect, which prevents deformation or cracking caused by temperature changes during use and extends the service life of the pressure plate body.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a clutch pressure plate with good heat dissipation, comprising a pressure plate body, a central hole at the center of the pressure plate body, the pressure plate body comprising an inner plate surface and an outer plate surface; a plurality of rivet holes are arranged in a circular array on the top edge of the pressure plate; the height of the inner plate surface gradually decreases towards the central hole, and a thickened sleeve is provided on the outer plate surface; a plurality of short protruding ridges are arranged in a circular array on the top of the thickened sleeve, and a plurality of arc-shaped heat dissipation grooves are arranged in a circular array on the top of the thickened sleeve and the pressure plate body, all of the short protruding ridges being located between two adjacent arc-shaped heat dissipation grooves; a long protruding ridge is provided on the side of the arc-shaped heat dissipation groove away from the short protruding ridges, and two adjacent long protruding ridges are in a figure-eight shape.

[0006] Preferably, the outer circumferential wall of the thickened sleeve is provided with a circular array of several inwardly recessed pressure plate rivet grooves, and the rivet holes are located in the pressure plate rivet grooves.

[0007] Preferably, the outer wall of the thickened sleeve has a plurality of wave-shaped heat dissipation grooves, which are located between two adjacent pressure plate rivet grooves.

[0008] Preferably, the top circular array of the inner disk surface is provided with a plurality of heat dissipation ridges.

[0009] Preferably, the top circular array of the inner disk surface is provided with a plurality of recessed holes, the recessed holes being located between two adjacent heat dissipation ridges.

[0010] Preferably, the pressure plate body is made of HT200 gray cast iron.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0012] This invention, by thickening the sleeve on the pressure plate body and incorporating an arc-shaped heat dissipation groove on the thickened sleeve, avoids slippage when the clutch pedal is released and the clutch disc comes into contact with the clutch. Simultaneously, the short and long protruding ridges on the thickened sleeve enhance the strength of the pressure plate body. When the pressure plate body rotates, the arc-shaped heat dissipation grooves, short and long protruding ridges increase the contact area with the atmosphere, increasing the heat dissipation area while maintaining the rigidity and strength of the pressure plate. This allows heat to be carried away from the pressure plate body, reducing the temperature of the pressure plate and friction plates, thereby preventing deformation or cracking due to temperature changes during use and extending the service life of the pressure plate body.

A number of rivet holes 5 are arranged in a circular array on the top edge of the pressure plate. The height of the inner plate surface 3 gradually decreases towards the central hole 2. A thickened sleeve 6 is provided on the outer plate surface 4. A number of short protruding ridges 7 are arranged in a circular array on the top of the thickened sleeve 6. A number of arc-shaped heat dissipation grooves 8 are arranged in a circular array on the top of the thickened sleeve 6 and on the pressure plate body 1. All the short protruding ridges 7 are located between two adjacent arc-shaped heat dissipation grooves 8. A long protruding ridge 9 is provided on the side of the arc-shaped heat dissipation groove 8 away from the short protruding ridges 7, and two adjacent long protruding ridges 9 are in the shape of an "eight".

[0019] In this embodiment: the thickened sleeve 6 is provided on the pressure plate body 1, and the arc-shaped heat dissipation groove 8 provided on the thickened sleeve 6 avoids the problem of slippage when the clutch pedal is released and the clutch plate comes into contact with it. At the same time, the short protrusion 7 and long protrusion 9 provided on the thickened sleeve 6 enhance the strength of the pressure plate body 1. When the pressure plate body 1 rotates, the arc-shaped heat dissipation groove 8, the short protrusion 7 and the long protrusion 9 increase the contact area with the atmosphere, increase the heat dissipation area, and maintain the rigidity and strength of the pressure plate. The heat on the pressure plate body 1 can be carried away, reducing the temperature of the pressure plate and friction plate, thereby avoiding deformation or cracking caused by temperature changes during use and extending the service life of the pressure plate body 1.

[0020] As a technical optimization of this utility model, the outer circumference of the thickened sleeve 6 is provided with a circular array of several inwardly recessed pressure plate rivet grooves 10, and the rivet holes 5 are located in the pressure plate rivet grooves 10.

[0021] In this embodiment, the pressure plate rivet groove 10 is easy to install rivets, and the protruding part of the pressure plate rivet groove 10 can carry away some of the heat on the pressure plate, thus having a heat dissipation effect.

[0022] As a technical optimization of this utility model, a number of wave heat dissipation grooves 11 are opened on the outer wall of the thickened sleeve 6, and the wave heat dissipation grooves 11 are located between two adjacent pressure plate rivet grooves 10.

[0023] In this embodiment, the wave-shaped heat dissipation groove 11 enables the pressure plate to produce a smoother transition during clutch engagement, which helps to reduce the impact and vibration during clutch engagement; at the same time, the wave-shaped heat dissipation groove 11 increases the contact area between the pressure plate and the air, thereby improving the heat dissipation effect.

[0024] As a technical optimization of this utility model, the top circular array of the inner disk 3 is provided with several heat dissipation ridges 12.

[0025] In this embodiment, the heat dissipation ridge 12 increases the contact area between the inner plate surface 3 and the cold airflow in the atmosphere, thereby increasing the heat dissipation area of ​​the inner plate surface 3, and the heat dissipation ridge 12 improves the rigidity and strength of the pressure plate.

[0026] As a technical optimization of this utility model, the top circular array of the inner disk surface 3 is provided with a number of recessed holes 13, and the recessed holes 13 are located between two adjacent heat dissipation ridges 12.

[0027] In this embodiment, the heat generated by the inner plate surface 3 can be dissipated into the atmosphere through the concave hole 13, effectively preventing the pressure plate body 1 from overheating and protecting it from damage.

[0028] As a technical optimization of this utility model, the pressure plate body 1 is made of HT200 gray cast iron.

[0029] In this embodiment: HT200 gray cast iron has high strength and wear resistance, and the carbon content of gray cast iron is usually 3%-3.6% and the silicon content is 1.4%-2%. These element contents give the pressure plate body 1 good mechanical properties and wear resistance.

[0030] Working principle and usage process of this utility model:

[0031] By providing a thickened sleeve 6 on the pressure plate body 1, and an arc-shaped heat dissipation groove 8 on the thickened sleeve 6, the problem of slippage when the clutch pedal is released and the clutch disc comes into contact with the clutch is avoided. At the same time, the short protrusion 7 and long protrusion 9 on the thickened sleeve 6 enhance the strength of the pressure plate body 1. When the pressure plate body 1 rotates, the arc-shaped heat dissipation groove 8, the short protrusion 7 and the long protrusion 9 increase the contact area with the atmosphere, increasing the heat dissipation area while maintaining the rigidity and strength of the pressure plate. This can remove the heat from the pressure plate body 1, reduce the temperature of the pressure plate and friction disc, thereby avoiding deformation or cracking caused by temperature changes during use and extending the service life of the pressure plate body 1.

[0032] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model.
