Description

Technical Field

[0002] The clutch pressure plate is one of the key components in the clutch system. It is usually a metal disc installed in the clutch assembly. The main function of the clutch pressure plate is to apply pressure to make the clutch plate contact or separate with the flywheel. When the driver steps on the clutch pedal, the clutch pressure plate will gradually transmit the power transmitted by the engine to the gearbox through the action of the pressure plate and the clutch spring, and finally drive the wheels.

[0003] After searching, the new clutch pressure plate with announcement number CN220769999U includes a main body and a plurality of ear pieces, and also includes: a plurality of reinforcing rib plates, wherein the plurality of reinforcing rib plates are used to reinforce the plurality of ear pieces; a fixing ring, wherein the fixing ring is located above the main body; a diaphragm spring is placed above the main body, and a plurality of limiting posts under the fixing ring are respectively passed through the through holes of the diaphragm spring, and a plurality of rivets are used to sequentially install the fixing ring, the limiting posts and the main body to fix the diaphragm spring to the main body; the use of the fixing ring ensures that if a rivet becomes loose during operation of the clutch pressure plate, the entire pressure plate will not be affected, thereby increasing the life of the pressure plate; a plurality of heat dissipation holes dissipate heat for the pressure plate, thereby preventing the temperature of the pressure plate from being too high and affecting the service life of the pressure plate; the reinforcing rib plates are used to reinforce the plurality of ear pieces to enhance the strength of the main body, thereby preventing the rebound force of the diaphragm spring acting on the ear piece from causing the main body to deform and reducing the life of the pressure plate.

[0004] Based on the above patent, its background technology mentions that when the pressure plate in the clutch presses the friction plate to engage with the flywheel, the clutch pressure plate will be significantly deformed under the reaction force of the diaphragm spring, resulting in a part of the outer pressure plate not pressing the friction plate, which is not conducive to the clutch engagement. In this regard, in order to solve this technical problem, this application proposes a pressure plate for a truck clutch. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0025] Reference Figure 1-3The utility model provides an embodiment: a pressure plate for a truck clutch, comprising a pressure plate body 1, a plurality of limit support arc plates 10 are evenly fixedly connected to the top of the pressure plate body 1, a plurality of mounting plates 3 are evenly fixedly connected to the outside of the pressure plate body 1, a torque support block 2 is fixedly connected to the left side of the mounting plates 3, a plurality of positioning notches 11 are opened on the inner side of the limit support arc plates 10 around the top of the pressure plate body 1, positioning and fixing columns 7 are inserted inside the positioning notches 11, a support and limiting component is installed outside the positioning and fixing columns 7, a cooling and heat dissipation component is installed inside the pressure plate body 1, and the support and limiting component includes A reinforcing support ring 8 is located outside the positioning and fixing column 7, and a plurality of limiting support blocks 6 are evenly and fixedly connected to the outside of the reinforcing support ring 8. The inside of the positioning and fixing column 7 is provided with a mounting through-slot 14, and the outside of the limiting support block 6 is respectively nested in the notch between the limiting support arc plates 10, and the inside of the mounting through-slot 14 is interspersed with a fixing bolt 15, and the top of the fixing bolt 15 is fixedly connected with a fixing sheet 9, and the bottom end of the inner part of the positioning notch 11 is provided with a fixing notch 12, and the bottom end of the fixing bolt 15 is respectively threadedly connected to the inside of the fixing notch 12, and the outer side of the reinforcing support ring 8 is respectively correspondingly fitted to the inner side of the limiting support arc plate 10;

[0026] When the pressure plate is assembled and installed, the multiple positioning and fixing columns 7 inside the reinforcing support ring 8 are respectively inserted into the interior of the positioning slots 11, and the outer side of the reinforcing support ring 8 is fitted to the inner side of the limiting support arc plate 10, and the limiting support block 6 is nested in the slot between the limiting support arc plates 10, so that the reinforcing support ring 8 and the limiting support arc plate 10 are tightly nested. At this time, the fixing bolt 15 is passed through the interior of the installation through-slot 14 and threadedly connected to the interior of the fixing slot 12, so that the reinforcing support ring 8 is fixed to the outside of the pressure plate body 1. When the shaft body generates a strong torque rotation force on the pressure plate body 1, the multiple limiting support arc plates 10 disperse the generated rotation force and transmit it to the reinforcing support ring 8, which is further stabilized by the mutual extrusion between the limiting support block 6 and the limiting support arc plate 10. At the same time, the torque support block 2 supports the mounting plate 3 to further offset the torque, thereby ensuring the stability of the installation, further improving the stability of the device, and improving the pressure plate's ability to resist compression and deformation, thereby further improving the service life of the pressure plate.

[0027] Reference Figure 1 , Figure 2 and Figure 4 The cooling and heat dissipation component includes a plurality of outer heat dissipation holes 4 located on the inner and outer sides of the pressure plate body 1, and a plurality of inner heat dissipation holes 5 are provided inside the pressure plate body 1 and inside the outer heat dissipation holes 4.

[0028] During the operation of the pressure plate, a higher temperature will be generated on the inner side of the pressure plate, and the temperature will be transmitted to the outside along the pressure plate body 1, and then transported to the outside along the heat dissipation grooves 13, and then discharged to the outside through the outer heat dissipation holes 4 and the inner heat dissipation holes 5. The heat is conducted to the outside through the heat dissipation grooves 13 and the pressure plate body 1 at the same time, and discharged to the outside through the outer heat dissipation holes 4 and the inner heat dissipation holes 5, thereby accelerating the heat dissipation efficiency, and quickly pulling the heat generated by friction on the inner side of the pressure plate when it is working to the outside, thereby further improving the heat dissipation ability of the device.

At this time, the fixing bolt 15 is passed through the inside of the installation through-slot 14 and threadedly connected to the inside of the fixing slot 12, so that the reinforcing support ring 8 is fixed to the outside of the pressure plate body 1. When the shaft body generates a strong torque rotation force on the pressure plate body 1, the multiple limiting support arc plates 10 will distribute the generated rotation force. The heat is dispersed and transmitted to the reinforcing support ring 8, and is further stabilized by the mutual squeezing between the limiting support block 6 and the limiting support arc plate 10. At the same time, the torque support block 2 supports the mounting plate 3 to further offset the torque, thereby ensuring the stability of the installation. During the operation of the pressure plate, a higher temperature will be generated on the inner side of the pressure plate, and the temperature will be transmitted to the outside along the pressure plate body 1, and transported to the outside along the heat dissipation grooves 13, and then discharged to the outside through the outer heat dissipation holes 4 and the inner heat dissipation holes 5, and the heat is conducted to the outside through the heat dissipation grooves 13 and the pressure plate body 1 at the same time, and discharged to the outside through the outer heat dissipation holes 4 and the inner heat dissipation holes 5, thereby accelerating the heat dissipation efficiency.
