Description

Technical Field

[0001] The utility model relates to the technical field of clutches, in particular to an anti-cracking automobile clutch pressure plate. Background Art

[0002] The clutch is located in the flywheel housing between the engine and the gearbox. The clutch assembly is fixed to the rear plane of the flywheel with screws. The clutch output shaft is the input shaft of the gearbox. The torque generated by the engine is transmitted to the driven plate through the friction between the flywheel and the contact surface between the pressure plate and the driven plate. When the driver steps on the clutch pedal, the large end of the diaphragm spring drives the pressure plate to move backward through the transmission of the mechanical parts, and at this time the driven part is separated from the active part.

[0003] The current clutch pressure plate will heat up during use, and the pressure plate is generally made of solid material and has a certain thickness, so it is difficult for the pressure plate to quickly dissipate heat after heating up. After long-term use, the material will crack due to the high temperature environment, resulting in reduced friction performance. Therefore, the utility model proposes an anti-cracking automobile clutch pressure plate. Utility Model Content

[0006] Furthermore, the contact ring, the inner ring plate, the outer ring plate and the flap are an integrated structure, and the contact ring is made of a high temperature resistant metal material.

[0007] Furthermore, a plurality of through holes for passing the screw rods are formed on the side of the cover plate, and a nut is connected to the surface of one end of the screw rod passing through the through hole.

[0008] Furthermore, a circular opening is opened in the middle of the cover plate, and the diameter of the circular opening is the same as the diameter of the inner ring plate.

[0010] Furthermore, a plurality of heat dissipation holes are provided on the cover plate.

[0011] Furthermore, a plurality of connecting columns are fixed to the side of the cover plate away from the contact assembly.

[0012] Beneficial effects of the utility model:

[0013] When the utility model is in use, the anti-cracking automobile clutch pressure plate is provided with a cover plate, a contact assembly and a support heat dissipation assembly. The pressure plate body is composed of the cover plate and the contact assembly, and the contact assembly includes a contact ring, an inner ring plate and an outer ring plate. Therefore, the interior of the pressure plate is hollow in design, and the support heat dissipation assembly can ensure the strength of the pressure plate.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figure 1-Figure 4 As shown, it relates to an anti-cracking automobile clutch pressure plate, including a cover plate 1 and a contact assembly 2, the contact assembly 2 includes a contact ring 21 that is in contact with the clutch friction plate, an inner ring plate 22 is fixed on the surface of the contact ring 21 and close to its circular hole, an outer ring plate 23 is fixed on the side of the surface of the contact ring 21, a flap 24 is fixed on the side of the outer ring plate 23 away from the contact ring 21, a plurality of screws 25 for connecting the cover plate 1 are fixed on the surface of the flap 24, and a support heat dissipation assembly 6 is connected through the cover plate 1.

[0023] A plurality of connecting columns 8 are fixed to the side of the cover plate 1 away from the contact assembly 2 .

[0024] In this embodiment, the connecting column 8 is used to connect the spring sheet of the clutch, and the pressure plate can be driven to move through the spring sheet.

[0025] The contact ring 21 , the inner ring plate 22 , the outer ring plate 23 and the flap 24 are an integrated structure, and the contact ring 21 is made of high temperature resistant metal material.

[0026] When the pressure plate is in use, the contact ring 21 is in contact with the friction plate, so the temperature of the contact ring 21 will increase. The use of high-temperature resistant metal material can increase the service life of the contact ring 21.

[0027] A plurality of through holes 3 for passing the screw rods 25 are formed on the side of the cover plate 1 , and a nut 4 is connected to the surface of one end of the screw rod 25 passing through the through hole 3 .

[0028] When assembling the pressure plate, after the cover plate 1 and the flap 24 are attached to each other, the screw rod 25 is passed through the through hole 3 on the cover plate 1 , and then the nut 4 is screwed on the screw rod 25 .

[0029] A circular opening 5 is formed in the middle of the cover plate 1 , and the diameter of the circular opening 5 is the same as the diameter of the inner ring plate 22 .

[0030] The circular opening 5 and the middle portion of the inner ring plate 22 are used for passing the drive shaft of the gearbox.

[0031] The support heat dissipation assembly 6 includes a plurality of arc-shaped pieces 61 penetrating the cover plate 1 . A heat-conducting ring plate 62 is fixedly connected to one side of the plurality of arc-shaped pieces 61 . The heat-conducting ring plate 62 is in contact with the contact ring 21 .

[0032] Since the heat conductive ring plate 62 is in contact with the contact ring 21, the arc-shaped sheet 61 also supports the contact assembly 2. Therefore, although a hollow space is formed inside the cover plate 1 and the contact assembly 2, the strength of the pressure plate can still be guaranteed and the weight of the pressure plate can be reduced.

[0033] The cover plate 1 is provided with a plurality of heat dissipation holes 7. The heat dissipation holes 7 can further improve the heat dissipation effect after the contact ring 21 is heated.

[0034] Working principle: The pressure plate can be fixedly connected to the spring sheet through the connecting column 8. When the pressure plate is in use, the contact ring 21 will contact the friction plate of the clutch, causing the temperature of the contact ring 21 to increase, and the contact ring 21 will conduct the heat to the heat-conducting ring plate 62, and then transfer it to a number of arc-shaped sheets 61 through the heat-conducting ring plate 62, thereby increasing the heat dissipation area, achieving rapid heat dissipation of the contact ring 21, and avoiding cracking due to high temperature. Therefore, the pressure plate not only has good heat dissipation, but also has the characteristics of light weight.
