Description

Technical Field

[0001] This utility model relates to the field of clutch pressure plate technology, and in particular to a clutch pressure plate structure. Background Technology

[0002] In the automotive clutch system, the clutch pressure plate is the core component that enables the separation and engagement of power between the engine and the transmission. Its performance directly affects the smoothness of gear shifting, power transmission efficiency, and service life of the vehicle.

[0003] In the long-term use of existing clutch pressure plate structures, the connection between the pressure plate and the internal elastic element is mostly fixed with a single bolt or welded. This is prone to loosening or cracking at the weld due to vibration and uneven stress, resulting in unstable pressure plate pressure and affecting the reliability of power transmission. In addition, the bottom of the pressure plate is in direct contact with the driven plate, and wear is severe after long-term friction. In traditional structures, the pressure plate body and wear-resistant parts are mostly designed as one piece, and the entire pressure plate needs to be replaced after wear, which not only increases the cost of parts but also extends the maintenance time. Utility Model Content

[0004] The purpose of this invention is to provide a clutch pressure plate structure to solve the defect that the existing clutch pressure plate structure is not easy to connect securely.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a clutch pressure plate structure, including a pressure plate;

[0006] The pressure plate has a connecting structure installed inside. The connecting structure includes an annular groove at the top of the pressure plate, a support ring installed inside the annular groove, a disc spring fixed inside the support ring, a release finger fixed inside the disc spring, an installation hole at the edge of the support ring, a connecting hole at the bottom of the annular groove, a first bolt installed inside the installation hole and the connecting hole, a first nut installed outside the first bolt inside the connecting hole, and a locking sleeve fitted outside the connecting hole at the bottom end of the first nut.

[0007] An installation structure is installed at the bottom of the pressure plate.

[0008] Preferably, the outer side of the support ring is fitted into the inner side of the annular groove, the separation fingers are evenly distributed inside the disc spring, and the center points of the pressure plate and the disc spring are located on the same straight line.

[0009] With the above structure, the annular groove positions the support ring on the pressure plate during use, ensuring accurate installation and preventing offset. This ensures that the center points of the pressure plate and the disc spring are on the same straight line, allowing the elastic force generated by the disc spring to be evenly transmitted to the pressure plate along the central axis, thus ensuring uniform pressure distribution of the pressure plate on the driven plate.

[0010] Preferably, the mounting holes are evenly spaced at the edge of the support ring, and the connecting holes are evenly spaced at the bottom of the annular groove. The mounting holes and connecting holes correspond one-to-one, and the bottom of the connecting holes extends through the interior of the pressure plate to the bottom of the pressure plate.

[0011] With the above structure, the installation holes and connection holes are evenly distributed during use, and the connection between the first bolt and the first nut can make the force between the support ring and the pressure plate evenly distributed on each connection point, avoiding loosening or damage caused by excessive local stress, thereby enhancing the connection stability of the overall structure.

[0012] Preferably, the first bolt and the first nut are threaded together, the locking sleeve is made of rubber, and the inside of the locking sleeve fits into the outside of the first bolt.

[0013] With the above structure, the support ring is firmly fixed in the annular groove of the pressure plate by the first bolt and the first nut during use. The locking sleeve is made of rubber, which has good elasticity and friction. When the locking sleeve is placed on the outside of the first bolt, it will generate a certain clamping force on the first bolt, which can effectively prevent the first bolt and the first nut from rotating relative to each other due to vibration, impact and other factors during clutch operation, thereby preventing the connection from loosening and ensuring the long-term stability of the connection between the support ring and the pressure plate.

[0014] Preferably, the mounting structure includes a wear-resistant bottom ring mounted on the bottom of the pressure plate, a first connecting block fixed to the outer side of the pressure plate, a second connecting block fixed to the outer side of the wear-resistant bottom ring, through holes provided inside the first and second connecting blocks, a second bolt installed inside the through holes, a second nut installed outside the second bolt, and a heat dissipation groove provided at the bottom end of the wear-resistant bottom ring.

[0015] Preferably, the outer diameter of the wear-resistant bottom ring is the same as the outer side of the pressure plate, the first connecting blocks are evenly distributed on the outer side of the pressure plate, the second connecting blocks are evenly distributed on the outer side of the wear-resistant bottom ring, and the first connecting blocks and the second connecting blocks correspond one-to-one.

[0016] The above structure ensures a stable connection through evenly distributed and precisely matched connecting blocks during use. This guarantees that the wear-resistant bottom ring moves synchronously with the pressure plate during operation without relative displacement. Consequently, the pressure applied by the pressure plate to the driven plate through the wear-resistant bottom ring is stable and uniform, ensuring smooth and reliable power transmission.

[0017] Preferably, the second bolt and the second nut are threaded together, and the heat dissipation grooves are distributed in a ring at equal intervals at the bottom end of the pressure plate.

[0018] With the above structure, the heat dissipation grooves are distributed in a ring at equal intervals at the bottom of the pressure plate during use, which can significantly increase the contact area between the wear-resistant bottom ring and the air. When the clutch is working, the friction between the wear-resistant bottom ring and the driven plate will generate a lot of heat. The ring at equal intervals can accelerate the dissipation of heat and prevent heat from accumulating in the wear-resistant bottom ring and surrounding parts.

[0019] The clutch pressure plate structure provided by this utility model has the following advantages:

[0020] By incorporating a connecting structure, where the outer side of the support ring engages with the inner side of the annular groove, and with evenly spaced mounting holes and connecting holes, a precise and secure connection between the support ring and the pressure plate is achieved through the threaded connection of the first bolt and the first nut. Furthermore, a rubber locking sleeve, whose inner side engages with the outer side of the first bolt, effectively prevents the first bolt and the first nut from loosening, further ensuring the stability of the connection and reducing clutch malfunctions caused by loose connections.

[0021] With its specially designed mounting structure, the wear-resistant bottom ring, installed at the bottom of the pressure plate, directly contacts the driven plate, bearing frictional wear and effectively protecting the pressure plate body, thus reducing pressure plate wear. Simultaneously, the wear-resistant bottom ring is connected to the pressure plate via a first connecting block, a second connecting block, a second bolt, and a second nut, facilitating its installation and replacement. Furthermore, the annularly spaced heat dissipation grooves at the bottom of the wear-resistant bottom ring increase the heat dissipation area, accelerating the dissipation of heat generated by friction, preventing aging of the wear-resistant bottom ring and surrounding components due to high temperatures, ensuring the clutch's performance stability after prolonged operation, and reducing malfunctions caused by high temperatures.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-5 The present invention provides a clutch pressure plate structure, including a pressure plate 1.

[0030] Reference Figures 1-4As shown, a connecting structure 2 is installed inside the pressure plate 1. The connecting structure 2 includes an annular groove 201 at the top of the pressure plate 1. A support ring 202 is installed inside the annular groove 201. A disc spring 203 is fixed inside the support ring 202. A separation finger 204 is fixed inside the disc spring 203. An installation hole 205 is provided at the edge of the support ring 202. A connecting hole 206 is provided at the bottom of the annular groove 201. A first bolt 207 is installed inside the installation hole 205 and the connecting hole 206. A first nut 208 is installed outside the first bolt 207 inside the connecting hole 206. A locking sleeve 209 is fitted outside the connecting hole 206 at the bottom of the first nut 208. The outer side of the support ring 202 is fitted into the inner side of the annular groove 201. The separation fingers 204 are evenly distributed inside the disc spring 203. The center points of the pressure plate 1 and the disc spring 203 are on the same straight line. The mounting holes 205 are evenly distributed at the edge inside the support ring 202. The connecting holes 206 are evenly distributed at the bottom end of the annular groove 201. The mounting holes 205 and the connecting holes 206 correspond one-to-one. The bottom end of the connecting hole 206 extends through the inside of the pressure plate 1 to the bottom end of the pressure plate 1. The first bolt 207 and the first nut 208 are threaded together. The locking sleeve 209 is made of rubber. The inside of the locking sleeve 209 is fitted into the outer side of the first bolt 207.

[0031] By installing the support ring 202 inside the annular groove 201, overall stability is ensured; the disc spring 203 provides axial elastic force through the equally spaced separation fingers 204 inside, while the first bolt 207 and the first nut 208 in the mounting hole 205 and the connecting hole 206 are fastened together, and the connection sealing is further enhanced by the locking sleeve 209 made of rubber material to avoid loosening and affecting pressure stability. The separation fingers 204 are equally spaced inside the disc spring 203 to ensure that the pressure plate is subjected to uniform force and to avoid uneven wear or jamming; then when the clutch is in the engaged state, the elastic force of the disc spring 203 is transmitted to the pressure plate 1 through the support ring 202, so that the pressure plate presses tightly against the driven plate, thereby transmitting the engine power to the gearbox through friction.

[0032] Reference Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, a mounting structure 3 is installed at the bottom of the pressure plate 1. The mounting structure 3 includes a wear-resistant bottom ring 301 installed at the bottom of the pressure plate 1. A first connecting block 302 is fixed to the outside of the pressure plate 1, and a second connecting block 303 is fixed to the outside of the wear-resistant bottom ring 301. Through holes 304 are provided inside the first connecting block 302 and the second connecting block 303. A second bolt 305 is installed inside the through hole 304. A second nut 306 is installed on the outside of the second bolt 305. A heat dissipation groove 307 is provided at the bottom of the wear-resistant bottom ring 301. The outer diameter of the wear-resistant bottom ring 301 is the same as that of the outside of the pressure plate 1. The first connecting blocks 302 are evenly distributed on the outside of the pressure plate 1, and the second connecting blocks 303 are evenly distributed on the outside of the wear-resistant bottom ring 301. The first connecting blocks 302 and the second connecting blocks 303 correspond one-to-one. The second bolt 305 and the second nut 306 are threadedly connected. The heat dissipation groove 307 is evenly distributed in a ring at the bottom of the pressure plate 1.

[0033] The wear-resistant bottom ring 301 is fixed to the pressure plate via the first connecting block 302 and the second connecting block 303. The second bolt 305 and the second nut 306 pass through the through hole 304 to connect the wear-resistant bottom ring 301 to the pressure plate 1, thus facilitating the separate installation and replacement of the wear-resistant bottom ring 301. The annular heat dissipation groove 307 at the bottom of the wear-resistant bottom ring 301 can quickly dissipate the heat generated by wear resistance, preventing high temperature from causing component aging or performance degradation.
