[0002] The clutch pressure plate is an important structure on the clutch. It is made of wear-resistant asbestos and copper wire. The most widely used type is the friction clutch with spring compression. 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, which plays an important role in the driving safety of the vehicle.

[0003] Chinese patent publication number CN222615866U discloses an anti-rotation device for a clutch cover assembly. This utility model includes a pressure cover, a diaphragm spring, a support ring, a fastening assembly, a connecting assembly, and a pressure plate. The diaphragm spring is fixedly connected to the pressure cover by rivets. The support ring abuts against both sides of the diaphragm spring. The outer sides of both support rings are provided with slots. The fastening assembly includes a slot seat that passes through the slot and through the diaphragm spring, a cover that is connected to the slot seat by screws, a first spring that is set at the top of the slot seat and the cover, an abutment block that is set at the top of the first spring, and a limiting rod that is set at the bottom of the abutment block. The connecting assembly is arranged inside the pressure cover, and the pressure plate is arranged on the left side of the connecting assembly.

[0004] In the clutch provided by this patent, the installation of the pressure plate is relatively complicated. Before installing the pressure plate, it needs to be manually positioned, which is inconvenient.

[0005] Therefore, a clutch pressure plate mounting structure is needed to solve the above problems. Utility Model Content

[0006] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0007] To address the technical problems mentioned in the background section, some embodiments of this application provide a clutch pressure plate mounting structure, including: a pressure cover, on which a flywheel is mounted by mounting bolts; a diaphragm spring, mounted on the pressure cover; and a pressure plate, mounted on the side of the diaphragm spring away from the pressure cover. The pressure plate has mounting portions distributed circumferentially, and a mounting structure is provided between the mounting portions and the pressure cover. The mounting structure includes: a fixing sleeve fixedly mounted on the mounting portions, and a threaded hole coaxially arranged with the fixing sleeve on the mounting portions; a positioning cylinder coaxially arranged with the fixing sleeve on the pressure cover; a sliding head slidably disposed within the positioning cylinder; a fixing bolt passing through the sliding head; and one end of the fixing bolt extending into the threaded hole and threadedly engaging with the threaded hole.

[0008] Furthermore, a transmission steel plate is provided between the mounting part and the pressure cover. One end of the transmission steel plate is fixed on the pressure cover by screws, and the other end of the transmission steel plate has a mounting hole. The sliding head passes through the mounting hole, and a pressure ring is provided on the sliding head. The pressure ring and the fixing sleeve are respectively clamped on both sides of the transmission steel plate.

[0009] Furthermore, the sliding head has a sliding end that is slidably disposed within the positioning cylinder, and a guide protrusion is fixedly disposed on the sliding end.

[0010] Furthermore, the retaining sleeve has an insertion end that is embedded within the retaining sleeve.

[0011] Furthermore, a driven plate is provided between the sliding head and the flywheel, and friction plates are fixedly installed on both sides of the driven plate.

[0012] Furthermore, a positioning part is fixedly provided on the pressure cap, and a positioning notch is provided on the diaphragm spring for the positioning part to pass through.

[0013] Furthermore, a positioning groove is provided on the pressure plate, and one end of the positioning part is inserted into the positioning groove through the positioning notch, and the positioning part is inserted into the positioning groove and slides in cooperation with the positioning groove.

[0014] The beneficial effects of this application are as follows:

[0015] With the sliding head, when the pressure plate is installed, one end of the sliding head is embedded in the fixed sleeve, which can pre-position the pressure plate and facilitate subsequent installation and fixation. With the fixed bolt and screw hole, when installation, one end of the fixed bolt is threaded into the screw hole, and the end of the fixed bolt squeezes the sliding end, so that the pressure ring on the sliding end fixes the transmission steel plate. With the sliding head, when installing the transmission steel plate, one end of the transmission steel plate is first fixed with a screw, and then the sliding head of the transmission steel plate passes through the installation hole of the transmission steel plate to pre-limit the transmission steel plate and prevent it from being installed in the subsequent pressure plate.

[0031] Reference Figure 1-5 A clutch pressure plate mounting structure includes: a pressure cover 10, a flywheel 11, mounting bolts 12, a diaphragm spring 13, a pressure plate 14, and a mounting part 15. The flywheel 11 is connected to the power output end of the engine. The pressure cover 10 is fixed to the flywheel 11 by the mounting bolts 12. The pressure plate 14 is mounted between the flywheel 11 and the pressure cover 10. A driven plate 16 is disposed between the flywheel 11 and the pressure plate 14. The driven plate 16 is connected to the power output shaft of the clutch. The pressure plate 14 presses the driven plate 16 against the flywheel 11 to output power. Friction plates are fixedly disposed on both sides of the driven plate 16. A diaphragm spring 13 is disposed between the pressure cover 10 and the pressure plate 14. The flywheel 11, driven plate 16, and diaphragm spring 13 can refer to existing clutch structures and will not be described in detail further. A circumferentially distributed positioning part 17 is fixedly provided on the pressure cover 10. A positioning notch 18 is provided on the diaphragm spring 13. The positioning part 17 limits the diaphragm spring 13 through the positioning notch 18. At the same time, a positioning groove 19 is provided on the pressure plate 14. The positioning part 17 slides into the positioning groove 19 through one end of the positioning notch 18, thereby limiting the pressure plate 14.

[0032] Multiple mounting portions 15 are circumferentially distributed on the pressure plate 14. A fixing sleeve 22 is fixedly connected to each mounting portion 15. Each mounting portion 15 also has a threaded hole 27 coaxially aligned with the fixing sleeve 22. A positioning cylinder 23 coaxially aligned with the fixing sleeve 22 is provided on the pressure cover 10. A sliding head 24 is slidably disposed within the positioning cylinder 23. A fixing bolt 26 passes through the sliding head 24, with one end extending into the threaded hole 27 and threadedly engaging with it. When the pressure plate 14 is installed, the fixing bolt 26 passes through the pressure plate 14 and is threadedly connected to the threaded hole 27.

[0033] The sliding head 24 has a sliding end 29 slidably disposed within the positioning cylinder 23. A guide protrusion 31 is fixedly disposed on the sliding end 29. A groove 30 is formed inside the positioning cylinder 23, and the guide protrusion 31 is embedded in the groove 30 and slides along the groove 30. When installing the pressure plate 14, one end of the sliding head 24 extends into the fixing sleeve 22 to position the pressure plate 14. At the same time, the sliding head 24 guides the pressure plate 14 to apply pressure evenly to the driven plate 16.

[0034] A transmission steel plate 20 is provided between the mounting part 15 and the pressure cover 10. One end of the transmission steel plate 20 is fixed to the pressure cover 10 by a screw 21, and the other end of the transmission steel plate 20 has a mounting hole through which a sliding head 24 passes. A pressure ring 25 is provided on the sliding head 24, and the pressure ring 25 and the fixing sleeve 22 are respectively clamped on both sides of the transmission steel plate 20. When one end of the fixing bolt 26 is inserted into the screw hole 27 and the fixing bolt 26 is tightened, the head end of the fixing bolt 26 will abut against the sliding end 29, causing the sliding head 24 to move until the pressure ring 25 abuts against one side of the transmission steel plate 20 to position the transmission steel plate 20.

[0035] The fixing sleeve 22 has an insertion end 28 that is embedded in the fixing sleeve 22. When installing the transmission steel plate 20, the insertion end 28 is first passed through the mounting hole of the transmission steel plate 20, and then the transmission steel plate 20 is fixed on the pressure cover 10 by screws 21 to pre-position the transmission steel plate 20, which facilitates the subsequent installation of the pressure plate 14.

[0036] Working process or usage method:

[0037] 1. During installation, first insert the insertion end 28 through the mounting hole of the transmission steel plate 20, and then fix the transmission steel plate 20 to the pressure cover 10 with screws 21 to pre-position the transmission steel plate 20. Then install the pressure plate 14 by inserting one end of the sliding head 24 into the fixing sleeve 22 to guide the pressure plate 14. At the same time, the positioning part 17 and the positioning groove 19 are used to limit the installation position of the pressure plate 14.

[0038] 2. Then, insert the fixing bolt 26 through one end of the fixing sleeve 22 into the screw hole 27. By tightening the fixing bolt 26, the end of the fixing bolt 26 abuts against one end of the sliding end 29, thereby causing the sliding end 29 to move closer to the pressure plate 14. This causes the pressure ring 25 and the fixing sleeve 22 to abut against both ends of the transmission steel plate 20, limiting the transmission steel plate 20. At this time, the insertion end 28 slides in the fixing sleeve 22. Through the sliding end 29 and the positioning cylinder 23, the pressure plate 14 is guided, so that the pressure plate 14 applies pressure evenly to the driven plate 16.
