Have been. A bent portion 31b bent inward is formed at the tip of the extension portion 31a, and the bent portion 31b is engaged with the engaging portion 7c of the flywheel 7. As a result, the clutch cover 31 cannot move toward the transmission with respect to the flywheel 7. A notch extending in the circumferential direction is formed at the tip of the extension portion 31a, and a plate 42 also extending in the circumferential direction is engaged with the notch. The plate 42 is fixed to the outer peripheral surface of the flywheel 7 by bolts 43. In this way, the clutch cover 31 cannot rotate relative to the flywheel 7 in the circumferential direction. By eliminating the bolt mounting seat of the flywheel in this manner, the flywheel 7 is reduced in size in the radial direction.
[0020]
The pressure plate 32 is an annular member arranged inside the clutch cover 31. The pressure plate 32 is formed with a pressing surface 32 a facing the friction surface 7 a of the flywheel 7.

A connection plate 34 is fixed to the other end of each stud pin 35. Wire rings 36 are arranged between the connection plate 34 and the diaphragm spring 33 and between the diaphragm spring 33 and the clutch cover 31 on the outer peripheral side of each stud pin 35. That is, the inner peripheral portion of the annular pressing portion 33 b of the diaphragm spring 33 is supported by being sandwiched between the pair of wirings 36.
[0023]
The connecting plate 34 is an annular member, and three connecting portions 34a extending in the circumferential direction R1 are integrally formed on the inner peripheral portion thereof. The distal end of the connecting portion 34a is fixed to the flange portion 32c of the pressure plate 32 by a rivet 37. The position of the rivet 37 is in the second hole 33 of the diaphragm spring 33.dIt corresponds to.

The inner peripheral end of the cone spring 38 is supported by the connection plate 34, and the outer peripheral end of the cone spring 38 urges the outer peripheral end of the diaphragm spring 33, that is, a portion close to the annular projection 32 b of the pressure plate 32 in a direction away from the pressure plate 32. . As described above, the connection plate 34 connects the clutch cover 31 and the pressure plate 32 and supports the cone spring 38 and the wiring 36. As described above, by providing the connecting plate 34 with multiple functions, the number of components is reduced.
[0025]
The plurality of locking members 40 are fixed to the pressure plate 32 by fixing pins 39, and one end of the plurality of locking members 40 sandwiches the outer peripheral end of the diaphragm spring 33 between the annular projection 32 b of the pressure plate 32.
The clutch disk assembly 10 has a friction facing 45 disposed between the friction surface 7a of the flywheel 7 and the pressing surface 32a of the pressure plate 32. The friction facing 45 is fixed to the hub 46 via a plate member.

[0027]
Although the bolt 49 is shown in FIG. 1, the bolt 49 is not used when the clutch device 1 is used. The bolt 49 is used when assembling or disassembling the clutch cover assembly 8 to the flywheel 7. The plurality of bolts 49 pass through holes formed in the inner peripheral end of the clutch cover 31, further pass through the first holes 33 c of the diaphragm spring 33, further penetrate the connection plate 34, and are screwed at the ends into the pressure plate 32. I agree.
[0028]
Next, the operation of the clutch device 1 will be described.
When the crankshaft on the engine side rotates, torque is transmitted to the flywheel 7 via the flexible plate 3 and the viscous damper mechanism 5, further transmitted to the clutch disk assembly 10, and finally output to the main drive shaft 50. The pressure plate 32 rotates integrally with the clutch cover 31 via the connection plate 34. Since the rotation of the pressure plate 32 is performed by the connection plate 34 that connects the inner periphery of the pressure plate 32 and the inner periphery of the clutch cover 31 as described above, the outer periphery of the clutch cover 31 is different from the related art. There is no need to provide a notch for accommodating the strap plate. For this reason, the strength of the clutch cover 31 is improved.
[0029]
Since the inertia member 4 is fixed to the first and second input plates 18 and 19, a sufficient inertia moment of the input system is secured in the input / output system of the power divided into the input system and the output system with the bent leaf spring 23 as a boundary. it can. Since the inertia member 4 is arranged on the outer peripheral portion, the first and second input plates 18 and 19, which are members constituting the viscous fluid filling chamber, can be made thin in the axial direction. As a result, the entire clutch device 1 is reduced in size in the axial direction. Furthermore, since the inertia member 4 extends in the axial direction, the entire clutch device 1 does not become too large in the radial direction. Even if the inertia member 4 is provided on the outer peripheral portion of the viscous damper mechanism 5, the size of the apparatus does not increase in the radial direction because the clutch mounting seat is eliminated from the flywheel 7 and the inertia member 4 is moved radially inward. This is because it can now be placed in
[0030]
When bending vibration is transmitted from the engine side, the bending vibration is absorbed by bending the flexible plate 3 in the bending direction.
When the torsional vibration is transmitted from the engine side, the first and second input plates 18 and 19 and the flywheel 7 perform periodic relative rotation. At this time, the curved leaf spring 23 is compressed in the circumferential direction, and the viscous fluid flows between the curved leaf spring 23 and the first and second input plates 18 and 19 in the viscous fluid filling chamber to generate viscous resistance. As a result, torsional vibration is effectively attenuated.
[0031]
When the driver steps on the clutch pedal, one end of the release device 54 moves the inner peripheral end of the diaphragm spring 33 toward the engine. As a result, the outer peripheral end of the diaphragm spring 33 is separated from the annular projection 32b of the pressure plate 32. Then, the pressure plate 32 is separated from the friction facing 45 of the clutch disk assembly 10 by the urging force of the connecting portion 34a of the connecting plate 34. As a result, torque transmission from the flywheel 7 to the clutch disk assembly 10 is interrupted. During the release operation described above, since the cone spring 38 applies a load on the transmission side to the diaphragm spring 33, the release load is reduced, and the pedal effort is reduced.
[0032]
When assembling the clutch device 1, the flywheel 7 and the clutch cover assembly 8 are fixed in advance. Specifically, first, the clutch cover assembly 8 and the pressure plate 32 are fixed by bolts 49 so as to be immovable in the axial direction. The bolt 49 keeps the clutch cover 31 and the pressure plate 32 close to each other despite the load from the diaphragm spring 33. The clutch cover assembly 8 in this state is brought closer to the flywheel 7 side, and the clutch cover 31ExtensionThe portion 31a is moved through the gap between the engaging portions 7c of the flywheel 7. In this state, the clutch cover assembly 8 is rotated to engage the bent portion 31b with the engaging portion 7c. Next, the bolt 43 and the plate 42 are operated from the operation hole 4b and fixed to the flywheel 7, so that the clutch cover 31 and the flywheel 7 cannot be rotated relative to each other. When the bolt 49 is removed, the pressure plate 32 and the clutch cover 31 are urged by the diaphragm spring 33 in a direction separating in the axial direction, whereby the bent portion 31b and the engagement portion 7c are firmly connected in the axial direction.
[0033]
The mechanism including the viscous damper mechanism 5, the flywheel 7, the clutch cover assembly 8 and the clutch disc assembly 10 is fixed to the flexible plate 3 and the inertia member 4 by a plurality of bolts 20. Bolt 20 is attached to clutch cover 31ExtensionThrough the portion where the portion 31a is not formed, the portion where the engaging portion 7c of the flywheel 7 is not formed and the groove 4a of the inertia member 4, the outer peripheral portions of the first and second input plates 18 and 19 are inerted. It is fixed to the member 4. By fixing the bolt 20 from the transmission side in this manner, workability is improved as compared with the related art. The reason why the bolt 20 can be fixed from the transmission side is that the bolt mounting seat of the flywheel is eliminated, and the bolt 20 can be arranged more radially inward.
[0034]
When replacing the clutch disk assembly 10, the clutch cover 31 and the pressure plate 32 are fixed again by the bolts 49. Next, the bolt 43 and the plate 42 are removed, and then the clutch cover assembly 8 is rotated to release the engagement between the bent portion 31b and the engagement portion 7c. As described above, when the clutch disk assembly 10 is replaced, the operation is simple because it is only necessary to remove the clutch cover assembly 8 from the flywheel 7. If the outer periphery of the clutch cover has been caulked to the flywheel, the flywheel must also be removed at the same time. Further, since the clutch cover 31 is circumferentially engageable with and disengageable from the flywheel 7, the clutch cover 31 is not damaged when detached from the flywheel 7. Therefore, reuse after removal is possible.
Second embodiment
In the clutch cover assembly 8 shown in FIG. 4, the number of components is reduced by eliminating the wiring compared to the first embodiment. Instead, annular bent portions 31c and 34c are formed on the clutch cover 31 and the connection plate 34, respectively. The annular bent portions 31c and 34c sandwich the diaphragm spring 33 from both sides in the axial direction.
Third embodiment

The plate member 48 is an annular member and supports the wiring 36 and the cone spring 38. The other end of each strap plate 47 is a flange of the pressure plate 32Department32c is fixed by a rivet 37. In this way, the strap plate 47 is connected so that the pressure plate 32 rotates integrally with the clutch cover 31 and urges the pressure plate 32 away from the flywheel. Also in this case, since the clutch cover 31 and the pressure plate 32 are fixed on both inner peripheral sides, there is no need to provide a cutout for accommodating the strap plate in the clutch cover 31 as in the related art. As a result, the strength of the clutch cover 31 is improved. Further, the plate member 48 supports the wiring 36 and the cone spring 38.
Sixth embodiment
The clutch cover assembly 8 shown in FIG. 8 does not include the wiring 36 as compared with the fifth embodiment. Instead, annular bent portions 31c and 48c are formed on the clutch cover 31 and the plate member 48, respectively. These annular bent portions 31c and 48c areAThe flam spring 33 is supported from both axial sides.

[0038]
【The invention's effect】
In the clutch device according to the present invention, when assembling the clutch cover assembly to the flywheel, the clutch cover assembly is bent by passing the bent engagement portion of the clutch cover between the engagement portions of the flywheel and then rotating the clutch cover. The engaging portion is engaged with the engaging portion of the flywheel. Subsequently, the flywheel and the clutch cover are disabled from rotating relative to each other by the fixing member. When the clutch cover assembly is removed from the flywheel, the above operation is performed in reverse. As described above, since the clutch mounting seat of the flywheel is eliminated, the flywheel is downsized in the radial direction. Further, since the clutch cover is circumferentially engageable with and disengageable from the flywheel, the clutch cover can be reused after being removed without being damaged at the time of removal.
