Description

Technical Field

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

[0002] The clutch is a component in the automotive transmission system that separates and connects the powertrain. It is one of the main components of a car and is located inside the flywheel housing between the engine and the gearbox. The clutch assembly is fixed to the rear surface of the flywheel with screws, and the output shaft of the clutch is the input shaft of the gearbox.

[0003] Existing clutches are mainly divided into diaphragm clutches and helical clutches. Traditional diaphragm clutches are widely used, have a relatively simple structure, are mass-produced, but have a short lifespan. Their structure includes a pressure plate, pressure plate, diaphragm spring, support pins, support rings, and transmission plates. The transmission plates connect the clutch pressure plate and pressure plate. Because the clutch is constantly disengaging and engaging during operation, the diaphragm spring and pressure plate support ring are prone to wear due to constant contact, causing changes in their contact point. This affects the clutch's leverage ratio, resulting in significant variations in the clutch's clamping and disengaging forces. The separation and connection of torque transmission between the pressure plate and friction plates leads to continuous wear on the pressure plate contact surface, resulting in large fluctuations in the pressure plate clamping force. This easily causes starting shuddering and abnormal noises, significantly impacting the clutch's lifespan.

[0004] Therefore, a clutch cover structure 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 above, some embodiments of this application provide a clutch cover structure, comprising: a main body having a plurality of circumferentially distributed connecting ears on the main body; and a support ring component disposed inside the main body. The support ring component includes: an abutment ring and a support ring, the abutment ring and the support ring being rotatably engaged, one side of the abutment ring abutting against a diaphragm spring, and circumferentially distributed support blocks fixedly disposed on the main body. The support ring has a plurality of sets of support platforms circumferentially distributed, one set of support platforms including a plurality of supports with progressively increasing heights, and the support blocks abutting against the support platforms.

[0007] Furthermore, bolt holes are provided on the support platform, and bolts are installed on the main body. Multiple sets of bolts are provided, with one end of each bolt threaded into the bolt hole, thereby fixing the main body and the support ring together.

[0008] Furthermore, multiple sleeves are fixedly arranged circumferentially on the abutment ring, and a connecting rod corresponding to the sleeve is fixedly arranged on the main body. The sleeve is inserted into the connecting rod and slides with the connecting rod. A spring is connected between the sleeve and the inner wall of the connecting rod, and the two ends of the spring are fixedly connected to the sleeve and the connecting rod respectively.

[0009] Furthermore, a central hole is provided on the main body, and multiple sets of circumferentially distributed bent pieces are fixedly installed on the support ring, with one end of the bent piece extending into the central hole and fitting against the inner wall of the central hole.

[0010] Furthermore, the main body is provided with connecting ears, a transmission bar is installed on the connecting ears, and multiple mounting platforms are provided on the connecting ears. One end of the transmission plate is installed on the mounting platform, and the multiple mounting platforms have a height difference.

[0011] Furthermore, the connecting ear has multiple screw holes located on the mounting platform. Screws are installed in the screw holes to fix the transmission plate to the connecting ear.

[0012] Furthermore, multiple evenly distributed guide blocks are fixedly installed at the lower end of the abutment ring.

[0013] The beneficial effects of this application are as follows: By using the abutment ring and support ring, when the diaphragm spring wears out, the abutment ring will no longer be tightly attached to the diaphragm spring or the tightness will be insufficient. By adjusting the support block to a support platform that is farther away from the diaphragm spring, the support ring can be tightly attached to the diaphragm spring to ensure the tightness. By mounting one end of the transmission plate onto different mounting platforms, the elasticity and transmission effect of the transmission plate are ensured. Anti-disengagement shoulders are set to prevent the transmission plate from coming off, and fixing screws are used to fix the transmission plate. Attached Figure Description

[0022] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] Reference Figure 1-8 A clutch cover structure includes: a main body 10, connecting ears 11, and a support ring 12. The main body 10 serves as a component of the clutch; the clutch's limiting groove 31 is connected via a transmission plate 24. A diaphragm spring 30 is provided between the main body 10 and the connecting ears 11. The specific structure and connection method of the diaphragm spring 30 and the limiting groove 31 can be derived from existing clutch structures and will not be described in detail here. The main body 10 has four circumferentially distributed connecting ears 11, on which the transmission plate 24 is mounted. Two mounting platforms 20 are provided on the connecting ears 11. One end of the transmission plate 24 is mounted on the mounting platform 20, and the other end of the transmission plate 24 is connected to the limiting groove 31 and fixed with screws. It should be noted that the two mounting platforms 20 have different heights. By mounting one end of the transmission plate 24 onto different mounting platforms 20, the elasticity and transmission effect of the transmission plate 24 are ensured. An anti-disengagement shoulder 23 is provided on one side of the mounting platform 20 to block the transmission plate 24 and prevent it from disengaging.

[0024] A support ring 12 is disposed on one side of the main body 10, located between the diaphragm spring 30 and the main body 10. One side of the support ring 12 abuts against the main body 10 to support the diaphragm spring 30. The support ring 12 needs to press firmly against the diaphragm spring 30 and ensure a certain pressing force. The support ring 12 includes an abutment ring 25 and a support ring 26, which are rotatably connected. One side of the abutment ring 25 abuts against the diaphragm spring 30. Multiple guide blocks 14 are fixedly disposed on one side of the abutment ring 25. The diaphragm spring 30 has a guide groove 32 for the guide blocks 14 to be inserted into, and a limiting groove 31 has a 33. One end of the guide block 14 is embedded in the 33, and the guide block 14 limits the movement of the diaphragm spring 30 and the 33. One end of the support ring 26 abuts against the main body 10. When the guide block 14 wears down, causing large fluctuations in the clamping force, the support ring 12 is adjusted to compensate for the diaphragm spring 30. Specifically, four sets of evenly distributed support platforms 16 are provided on one side of the support ring 26. Each set of support platforms 16 includes multiple platforms, and the heights of the multiple support platforms 16 change sequentially, for example, by raising or lowering them sequentially. A support block 18 is fixedly provided on the main body 10, abutting against the support platform 16. Initially, the support block 18 is supported on the support platform 16 closest to the diaphragm spring 30. When the diaphragm spring 30 wears down, the abutting ring 25 no longer adheres tightly to the diaphragm spring 30 or the adhesion is insufficient. By adjusting the support block 18 to a support platform 16 farther away from the diaphragm spring 30, the support ring 12 can press tightly against the diaphragm spring 30, ensuring the clamping force.

[0025] In one embodiment, bolt holes 17 are provided on the surface of the support platform 16, and bolts 19 are installed on the main body 10. When fixing the support ring 26 to the main body 10, one end of the bolt 19 is threaded into the bolt hole 17. At this time, the support ring 26 and the main body 10 are fixed, preventing relative rotation. At the same time, a bent piece 13 is fixed on the support ring 26. A central hole 15 is provided at the center of the main body 10. One end of the bent piece 13 extends into the central hole 15 and abuts against the side of the central hole 15. The central hole 15 limits the positioning of the support ring 26 and the main body 10, preventing displacement when adjusting the support ring 26. Similarly, by removing the bolts 19, the central hole 15 can be rotated to position different support platforms 16 relative to the support blocks 18. Four support blocks 18 are provided to ensure stability. It should be noted that when one side of the support block 18 abuts against the wall of one side of the support platform 16, the bolt 19 is directly opposite the bolt hole 17 provided on the support platform 16.

[0026] Multiple sets of circumferentially distributed connecting rods 28 are fixedly installed on the main body 10. Multiple sleeves 27 are fixedly connected to the support ring 26. The sleeves 27 are sleeved with the connecting rods 28 and slide in cooperation with the connecting rods 28. A spring 29 is connected between the inner wall of the sleeve 27 and the connecting rod 28. The two ends of the spring 29 are fixedly connected to the sleeve 27 and the connecting rod 28, respectively. The connecting rods 28 and the springs 29 prevent relative rotation between the support ring 26 and the main body 10.

[0027] Working process or usage method: 1. Initially, the support block 18 is supported on the support platform 16 closest to the diaphragm spring 30. When the diaphragm spring 30 wears down, the abutment ring 25 no longer adheres tightly to the diaphragm spring 30 or the adhesion is insufficient. By adjusting the support block 18 to the support platform 16 farther away from the diaphragm spring 30, the support ring 12 can abut against the diaphragm spring 30, ensuring the abutment force. The bolt 19 can be removed, and the different support platforms 16 can be positioned relative to the support block 18 by rotating the central hole 15. Through the connecting rod 28 and the spring 29, the relative rotation between the support ring 26 and the main body 10 is prevented, so that the support ring 26 always has sufficient adhesion force to the diaphragm spring 30.

[0028] 2. When fatigue deformation of the transmission plate 24 affects the transmission, the elasticity and transmission effect of the transmission plate 24 are ensured by installing one end of the transmission plate 24 on different mounting platforms 20. The transmission plate 24 is prevented from falling out by the anti-disengagement shoulder 23 and the transmission plate 24 is fixed by the fixing screw 21.

[0029] 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.
