Description

Technical Field

[0001] This application relates to the field of clutch pressure plate technology, and more specifically, to a clutch pressure plate assembly. Background Technology

[0002] When a car starts, it gradually accelerates from a completely stationary state. The clutch plate in the clutch is connected to the transmission system. Depressing the clutch pedal can separate the clutch plate from the engine flywheel. After the engine starts, the flywheel rotates. Gradually release the clutch pedal, and the clutch plate will gradually engage tightly with the flywheel under the pressure of the internal pressure plate. Driven by the flywheel, the car gradually starts moving.

[0003] Existing clutch pressure plates and covers are usually connected by a transmission plate. The transmission plate serves to transmit power and also provides a certain amount of axial movement extension for the pressure plate. When the clutch is depressed, the spring diaphragm drives the clutch plate to release. However, it is difficult to adjust the transmission plate during the installation of existing clutch pressure plates.

[0004] Therefore, a clutch pressure plate assembly is needed to solve the above problems. Utility Model Content

[0005] 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.

[0006] To address the technical problems mentioned in the background section, some embodiments of this application provide a clutch pressure plate assembly, including: a pressure cover, a pressure plate, a connecting member installed between the pressure cover and the pressure plate, a diaphragm spring installed inside the pressure cover between the pressure cover and the connecting member; a flywheel for transmitting engine power; a clutch plate abutting against the flywheel to transmit power to the output shaft; a fixing block fixedly disposed on the pressure cover, the fixing block having a sliding groove, an mounting block sliding along the axis of the pressure cover disposed in the sliding groove, one end of the connecting member being installed and connected to the mounting block by a first bolt group, and the other end of the connecting member being installed and connected to the pressure cover by a second bolt group; a threaded hole being provided on the mounting block, a through hole being provided on the fixing block, an adjusting screw passing through the through hole and inserted into the threaded hole and threadedly connected to the threaded hole, the distance between the mounting block and the pressure cover being adjusted by rotating the adjusting screw, thereby adjusting the deformation of the connecting member.

[0007] By using the fixed block and the mounting block, the mounting block can be moved by rotating the adjusting screw, which facilitates the adjustment of the deformation of the connecting parts. When the clutch is depressed, the center position of the diaphragm spring is pressed, so that the edge of the diaphragm spring no longer squeezes the pressure plate, and the clutch plate is released and no longer in contact with the flywheel to disengage from the transmission. At this time, the pressure plate is pulled away from the clutch plate under the action of the connecting parts.

[0008] Furthermore, a through groove is provided on the mounting block, and the first bolt group includes a bolt and a nut. After the bolt passes through the through groove and the connector, the nut is installed to fix the mounting block and the connector in place.

[0009] The first bolt group, which includes two nuts that turn in opposite directions, is designed to prevent the first bolt group from loosening.

[0010] Furthermore, multiple circumferentially distributed limiting blocks are fixedly installed on the pressure cap. Each limiting block includes a guide section and a limiting section. The diaphragm spring is provided with a positioning groove that matches the limiting block, and the limiting block limits the diaphragm spring.

[0011] The diaphragm spring and pressure plate can be limited by the set limit block.

[0012] Furthermore, the pressure plate is provided with an annular portion, and the annular portion has multiple embedding grooves and limiting grooves distributed circumferentially, the width of the embedding grooves and limiting grooves being consistent with that of the limiting block.

[0013] With the set embedding groove and limiting groove, when installing the pressure plate, the output shaft is first embedded into the embedding groove until the limiting block is at the bottom of the embedding groove. Then, by rotating the pressure plate, the limiting block is aligned with the limiting groove and can be embedded into the limiting groove. At this time, the circumferential movement range of the pressure plate is the size of the limiting groove, ensuring that the movement of the limiting groove is stable.

[0014] Furthermore, the bottom of the embedding groove is provided with a slot, which is connected to the top of the limiting groove, and the limiting groove and the embedding groove are staggered in the vertical direction.

[0015] Furthermore, the thickness of the limiting segment is consistent with the size of the slot, allowing the limiting segment to slide into the limiting groove through the slot.

[0016] Furthermore, a radially extending heat dissipation channel is provided inside the pressure plate, with both ends of the heat dissipation channel being connected.

[0017] With the heat dissipation channel in place, when the pressure plate rotates, one end of the heat dissipation channel moves faster. At this time, the air pressure is lower, which can draw the hot air near the center of the pressure plate to the outside and avoid the temperature from getting too high.

[0018] The beneficial effects of this application are as follows: 1. By using the fixed block and the mounting block, the mounting block can be moved by rotating the adjusting screw, which facilitates the adjustment of the deformation of the connecting parts. When the clutch is depressed, the center position of the diaphragm spring is pressed, so that the edge of the diaphragm spring no longer squeezes the pressure plate, and the clutch plate is released and no longer in contact with the flywheel to disengage from the transmission. At this time, under the action of the connecting parts, the pressure plate is pulled away from the clutch plate.

[0019] 2. With the set embedding groove and limiting groove, when installing the pressure plate, first embed the output shaft into the embedding groove until the limiting block is at the bottom of the embedding groove. Then, by rotating the pressure plate, the limiting block is aligned with the limiting groove and can be embedded into the limiting groove. At this time, the circumferential movement range of the pressure plate is the size of the limiting groove, ensuring that the movement of the limiting groove is stable.

[0020] 3. Through the heat dissipation channel, when the pressure plate rotates, one end of the heat dissipation channel moves faster. At this time, the air pressure is lower, which can draw the hot air near the center of the pressure plate to the outside and avoid the temperature from getting too high. Attached Figure Description

[0028] It should be noted that the terms "a" and "a plurality of" used in this disclosure are illustrative rather than restrictive, and those skilled in the art should understand that, unless otherwise expressly indicated in the context, they should be understood as "one or more".

[0029] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] Reference Figure 1-7A clutch pressure plate assembly includes: a pressure cover 10, a pressure plate 11, a connecting member 16, a diaphragm spring 25, a flywheel 12, a clutch disc 13, an output shaft 14, a fixing block 15, a sliding groove 22, a mounting block 17, a first bolt group 18, and a second bolt group 23. The connecting member 16 is installed between the pressure cover 10 and the pressure plate 11. The diaphragm spring 25 is installed inside the pressure cover 10, located between the pressure cover 10 and the connecting member 16. When the clutch is engaged, the transmission structure compresses the center of the diaphragm spring 25, causing the edge of the diaphragm spring 25 to no longer compress the pressure plate 11. This causes the clutch disc 13 to release and no longer contact the flywheel 12, disengaging from the transmission. At this time, the connecting member 16 pulls the pressure plate 11 away from the clutch disc 13. For specific structure details, refer to existing clutch technology. The engine drives the flywheel 12 to rotate. The clutch plate 13 is located on one side of the pressure plate 11. When the clutch plate 13 is squeezed and pressed against the flywheel 12 by the pressure plate 11, the clutch plate 13 rotates with the flywheel 12 and transmits power to the output shaft 14.

[0031] A fixing block 15 is fixedly installed on the pressure cover 10. The fixing block 15 has a sliding groove 22, and an installation block 17 is installed in the sliding groove 22, which slides along the axis of the pressure cover 10. One end of the connecting member 16 is installed and connected to the installation block 17 by a first bolt group 18, and the other end of the connecting member 16 is installed and connected to the pressure cover 10 by a second bolt group 23. The connecting member 16 can be a clutch transmission plate. During installation, the connecting member 16 and the installation block 17 are connected by the second bolt group 23 and the first bolt group 18. At this time, the pressure plate 11 rotates with the pressure cover 10 and can have a certain amount of axial movement through the connecting member 16.

[0032] The mounting block 17 has a threaded hole 21, and the fixing block 15 has a through hole. The adjusting screw 19 passes through the through hole and is inserted into the threaded hole 21, where it is threadedly connected. By rotating the adjusting screw 19, the distance between the mounting block 17 and the pressure cap 10 is adjusted, thereby adjusting the deformation of the connecting piece 16. Rotating the adjusting screw 19 moves the mounting block 17, facilitating the adjustment of the deformation of the connecting piece 16. When the clutch is depressed, the center position of the diaphragm spring 25 is pressed, so that the edge of the diaphragm spring 25 no longer presses against the pressure plate 11, causing the clutch plate 13 to release and no longer contact the flywheel 12, disengaging from the transmission. At this time, under the action of the connecting piece 16, the pressure plate 11 is pulled away from the clutch plate 13.

[0033] In one embodiment, a plurality of circumferentially distributed limiting blocks 24 are fixedly disposed on the pressure cap 10. Each limiting block 24 includes a guide section 28 and a limiting section 29. The diaphragm spring 25 has a positioning groove 26 adapted to the limiting block 24, and the limiting block 24 limits the diaphragm spring 25. When the diaphragm spring 25 is installed, the limiting block 24 can be embedded into the positioning groove 26 to guide the diaphragm spring 25.

[0034] The pressure plate 11 has an annular portion with multiple circumferentially distributed embedding grooves 27 and limiting grooves 30. The width of the embedding grooves 27 and limiting grooves 30 is the same as that of the limiting block 24. When installing the pressure plate 11, the limiting block 24 is first embedded into the embedding groove 27. Then, by rotating the pressure plate 11, the limiting block 24 is positioned in the limiting groove 30, allowing it to continue embedding into the limiting groove 30 for installation.

[0035] The bottom of the embedding groove 27 is provided with a slot, which communicates with the top of the limiting groove 30. The limiting groove 30 and the embedding groove 27 are staggered in the vertical direction, and the thickness of the limiting section 29 is the same as the size of the slot. When the pressure plate 11 rotates, the limiting section 29 rotates into the limiting groove 30 through the slot and can move along the limiting groove 30. At this time, the circumferential movement range of the pressure plate 11 is the size of the limiting groove 30, ensuring that the movement of the limiting groove 30 is stable.

[0036] The pressure plate 11 has four radially extending heat dissipation channels 31. The two ends of the heat dissipation channels 31 are connected. When the pressure plate 11 rotates, one end of the heat dissipation channel 31 moves faster. At this time, the air pressure is lower, which can draw the hot air near the center of the pressure plate 11 to the outside to avoid the temperature from getting too high and ensure the cooling effect.

[0037] Working process or usage method: 1. During installation, first install the diaphragm spring 25 inside the pressure cover 10, and use the limiting block 24 and positioning groove 26 for positioning and guidance. After the diaphragm spring 25 is installed, install the pressure plate 11. First, make the limiting section 29 embedded in the embedding groove 27. By rotating the pressure plate 11, make the limiting section 29 embedded in the limiting groove 30, and then install the pressure plate 11 in place. 2. The connector 16 is installed between the pressure plate 11 and the cover 10 by the first bolt group 18 and the second bolt group 23. When the connector 16 needs to be adjusted, the adjusting screw 19 is rotated to drive the mounting block 17 to move, thereby deforming the connector 16 and adjusting the connector 16 so that when the clutch is pressed again, the connector 16 pulls the pressure plate 11 to fully disengage from the clutch plate 13.

[0038] The above description is merely a selection of preferred embodiments of this disclosure and an explanation of the technical principles employed. Those skilled in the art should understand that the scope of the application involved in the embodiments of this disclosure is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the above-described application concept. For example, technical solutions formed by substituting the above-described features with (but not limited to) technical features with similar functions disclosed in the embodiments of this disclosure.
