[0002] The clutch is a crucial component in the automotive transmission system, enabling the cutting off and transmission of power between the engine and the gearbox. The pressure plate, as a key component of the clutch, is assembled with the clutch discs and achieves frictional engagement of the clutch by applying pressure.

[0003] In current engine assembly lines, to ensure that the clutch does not disengage completely after installation, preventing difficulties in shifting gears, the clutch pressure plate must be in a compressed state before tightening the clutch bolts. Furthermore, the coaxiality of the clutch driven plate and crankshaft must be guaranteed after the pressure plate is installed. Current technology often involves manual positioning and installation of the pressure plate, which is not only difficult to perform but also struggles to guarantee positioning accuracy after installation, frequently requiring disassembly and reassembly, making installation extremely inconvenient. Therefore, a clutch pressure plate clamping mechanism is proposed. Utility Model Content

Example

[0020] Please see Figure 1-5 This utility model provides a technical solution: a clutch pressure plate clamping mechanism, including a positioning ring seat 1, a positioning shaft 2, a clamping cylinder 3, a limiting pressure ring 4, and a spring 5 for assisting in pressure plate installation, as shown in the attached figure. Figure 3As shown, the positioning ring seat 1 is a circular ring seat. The positioning ring seat 1 is positioned and installed on the end seat of the clutch through screw holes. Specifically, in order to facilitate the positioning and installation of the positioning ring seat 1, mounting side seats 6 are uniformly fixed in a circular shape on the outer edge of the positioning ring seat 1. A bolt mounting hole is opened through the middle of the mounting side seat 6. A fastening bolt is installed on the inner side of the bolt mounting hole. The positioning ring seat 1 is fixed and installed on the end seat of the clutch through the fastening bolt. An external ring frame support positioning auxiliary structure is adopted. The positioning ring seat 1, which is positioned and installed on the end seat of the transmission, is used as the reference positioning structure. The positioning ring seat 1 is installed and positioned by the mounting hole position at the end of the transmission, which has good positioning accuracy and installation convenience.

[0021] To achieve the mounting support between the positioning shaft 2 and the clamping cylinder 3, as shown in the attached... Figure 3 As shown, a mounting bracket 7 is provided in the middle of the positioning ring seat 1. Three mounting brackets 7 are provided, arranged in a circumferential shape and integrally fixedly installed on the front middle of the positioning ring seat 1. The positioning shaft 2 is rotatably mounted in the middle of the positioning ring seat 1 supported by the mounting brackets 7. Specifically, see attached... Figure 4 As shown, to facilitate the support and installation of the positioning column 2, a mounting seat is integrally fixed on the cross side of the middle of the mounting bracket 7. The positioning column 2 is rotatably mounted on the middle of the mounting seat through bearing support. After installation, the end of the positioning column 2 is aligned and inserted into the transmission shaft hole in the middle of the clutch driven plate. During installation, the alignment and insertion of the positioning column 2 with the transmission shaft hole in the middle of the clutch disc, combined with the support and positioning of the positioning ring seat 1, can achieve the positioning and calibration of the coaxiality of the pressure plate installation, eliminating the complicated debugging and calibration operations, and effectively improving the convenience and accuracy of the pressure plate installation and positioning. To facilitate the rotation operation of the positioning column 2, see attached... Figure 3 As shown, a drive seat 8 is provided at the front of the positioning column 2. The drive seat 8 is fixedly installed at the front end of the positioning column 2. After the pressure plate is positioned, the positioning column 2 can be rotated by turning the drive seat 8. The installation positioning accuracy of the pressure plate can be pre-tested by the trial rotation of the clutch driven plate. The limiting pressure ring 4 is used for the pressure support of the pressure plate pressing part. The limiting pressure ring 4 is movably fitted to the outside of the positioning column 2 by the spring 5. Specifically, see attached... Figure 5 As shown, the limiting pressure ring 4 is circular. The limiting pressure ring 4 is movably mounted to the rear end of the positioning shaft 2. The rear end of the spring 5 is fixedly mounted to the front part of the limiting pressure ring 4, and the front end of the spring 5 is supported by the rear part of the mounting shaft seat.

[0022] The clamping cylinder 3 is a pneumatic cylinder, and it is supported and installed in the middle of the positioning ring seat 1 by the mounting bracket 7. See attached diagram for details. Figure 3 As shown, three clamping cylinders 3 are provided. The clamping cylinders 3 are fixedly installed to the front middle of the mounting bracket 7 by bolts. In order to facilitate contact and support with the pressure plate, as shown in the attached figure... Figure 4 As shown, a limiting block 9 is provided at the push rod end of the clamping cylinder 3. The limiting block 9 is a round rubber block. The limiting block 9 is fixedly installed with the push rod end of the clamping cylinder 3. An installation auxiliary structure is adopted for cylinder pre-clamping. The clamping cylinder 3 is installed on the mounting bracket 7 side of the positioning ring seat 1. After the pressure plate is installed and positioned, the pressure plate can be temporarily clamped and limited by pushing the support of the clamping cylinder 3. While providing pre-tightening pressure to the pressure plate, it can avoid the pressure plate displacement caused by bolt tightening operation, which is conducive to improving the installation convenience and installation accuracy of the pressure plate.

[0023] Working principle or structural principle: During operation, after the clutch disc is installed, the pressure plate is initially aligned and installed on the outer mating side of the disc. Then, the limiting pressure ring 4 is fitted onto the upper part of the positioning shaft 2. After completion, the mounting side 6 of the positioning ring seat 1 is aligned and aligned with the mounting hole on the upper part of the clutch end seat. The positioning ring seat 1 is then tightened with bolts to complete its positioning and installation. During installation, the position of the pressure plate is adjusted so that the positioning shaft 2 in the middle of the positioning ring seat 1 is aligned and engaged with the drive shaft hole in the middle of the disc. The limiting pressure ring 4 is then supported and installed on the pressure plate portion of the pressure plate. The alignment and engagement of the positioning shaft 2 with the drive shaft hole in the middle of the clutch disc, combined with the support and positioning of the positioning ring seat 1, allows for the coaxiality calibration of the pressure plate installation. Further adjustments to the pressure plate are then made. The installation position ensures that the pressure plate and the screw holes on the upper part of the disc are aligned and overlapped. Then, the bolts are initially inserted into the inner side of the screw holes. After completion, the internal disc is rotated by the drive seat 8 to ensure smooth rotation of the disc. Then, the pressure plate is stabilized and the air valve is opened. The three sets of clamping cylinders 3 work to make the limit pressure block 9 press against the outer edge of the pressure plate, temporarily clamping and limiting the positioning of the pressure plate. While providing pre-tightening pressure to the pressure plate, it can also prevent the pressure plate from shifting due to bolt tightening operations. After clamping, the disc is installed and adjusted again by turning the drive seat 8 to ensure smooth rotation of the disc. Then, the bolts are tightened and locked one by one by an electric wrench to complete the installation of the pressure plate. Afterwards, the clamping cylinder 3 is depressurized and reset, and the positioning ring seat 1 is removed to complete the installation.

[0024] In summary, this clamping mechanism adopts an external ring frame support positioning auxiliary structure. The positioning ring seat 1, which is positioned and installed with the transmission end seat, serves as the reference positioning structure. The positioning ring seat 1 relies on the mounting holes at the transmission end for installation and positioning, which has good positioning accuracy and installation convenience. A positioning column 2 is supported and installed in the middle of the positioning ring seat 1 by a mounting bracket 7. During installation, the positioning column 2 is aligned and inserted with the transmission shaft hole in the middle of the clutch disc, and the positioning ring seat 1 supports and positions the pressure plate to achieve coaxiality positioning calibration, eliminating complicated debugging and calibration operations. This effectively improves the installation and positioning convenience and accuracy of the pressure plate. The installation auxiliary structure for cylinder pre-clamping is adopted. A clamping cylinder 3 is installed on the mounting bracket 7 side of the positioning ring seat 1. After the pressure plate is installed and positioned, the clamping cylinder 3 pushes against the support to temporarily clamp and limit the positioned pressure plate. While providing pre-clamping pressure to the pressure plate, it can avoid pressure plate displacement caused by bolt tightening operations, which is conducive to improving the installation convenience and accuracy of the pressure plate.
