阅读说明：本技术 紧凑型离合器和离合器总成 (Compact clutch and clutch assembly ) 是由 尤世龙 于 2018-06-15 设计创作，主要内容包括：本发明提供了一种提高离合器内部空间利用率的紧凑型离合器和包括该离合器的离合器总成。该离合器包括离合器盖、杠杆系统、压盘和弹性件,杠杆系统设置在离合器盖与压盘之间,其中,弹性件设置于杠杆系统的远离离合器盖的盖端面的那侧,弹性件的固定端固定于离合器盖,弹性件具有远离固定端的自由端,自由端能与杠杆系统接触,自由端与杠杆系统的接触区域位于压盘与杠杆系统的接触区域的径向外侧,在包括离合器的离合器总成的分离过程中,弹性件始终与杠杆系统互相挤压而对杠杆系统施加朝向盖端面的作用力。弹性件的设置使离合器结构更紧凑、分离杠杆的杠杆比增加、且能在离合器发生磨损后有效降低分离力。(The invention provides a compact clutch capable of improving the utilization rate of the internal space of the clutch and a clutch assembly comprising the clutch. This clutch includes clutch cover, lever system, pressure disk and elastic component, lever system sets up between clutch cover and pressure disk, wherein, elastic component sets up in that side of the lid terminal surface of keeping away from clutch cover of lever system, the stiff end of elastic component is fixed in clutch cover, elastic component has the free end of keeping away from the stiff end, the free end can contact with lever system, the contact area of free end and lever system is located the radial outside of pressure disk and lever system's contact area, in the separation process of the clutch assembly including clutch, elastic component extrudees and exerts the effort towards the lid terminal surface with lever system each other all the time. The arrangement of the elastic piece enables the clutch structure to be more compact, the lever ratio of the release lever to be increased, and the release force can be effectively reduced after the clutch is abraded.)

1. A compact clutch comprising a clutch cover, a lever system, a pressure plate and a spring, the lever system being arranged between the clutch cover and the pressure plate, wherein,

the elastic part is arranged on the side of the lever system far away from the cover end face of the clutch cover, the fixed end of the elastic part is fixed on the clutch cover, the elastic part is provided with a free end far away from the fixed end, the free end can be contacted with the lever system, the contact area of the free end and the lever system is positioned on the radial outer side of the contact area of the pressure plate and the lever system,

during the separation process of the clutch assembly comprising the clutch, the elastic piece and the lever system are always mutually pressed to apply acting force towards the end face of the cover to the lever system.

2. The compact clutch of claim 1, wherein: the fixed end of the elastic member is fixed to the outer circumferential wall of the clutch cover.

3. The compact clutch of claim 1, wherein: the elastic member provides a supporting force for the lever system to keep the lever system in contact with the clutch cover during at least a part of the disengagement process of the clutch assembly.

4. The compact clutch of claim 1, wherein: after the clutch is assembled with the flywheel and the driven disc, the elastic piece is pressed by the lever system to be loaded with pretightening force.

5. The compact clutch of claim 1, wherein: when the clutch is not assembled with the flywheel and the driven disc and is in an initial state, the elastic piece is pressed by the lever system and is loaded with pretightening force.

6. The compact clutch of claim 1, wherein: after the clutch assembly finishes the separation action, the elastic piece and the lever system are still mutually extruded to apply acting force to the lever system.

7. The compact clutch of claim 1, wherein: the elastic component is hollow dish type, the stiff end is located the outer peripheral edges of elastic component, the free end is located the inner peripheral edges of elastic component.

8. The compact clutch according to any one of claims 1 to 7, characterized in that: the lever system comprises a disc-shaped diaphragm spring.

9. The compact clutch of claim 8, wherein: in the load-deformation curve, the deformation amount corresponding to the maximum bearable load of the diaphragm spring is approximately the same as the deformation amount corresponding to the maximum bearable load of the elastic member,

in the load-deformation curve, when the diaphragm spring is at the predetermined working position, the actual load borne by the elastic member is less than the maximum bearable load of the elastic member.

10. A clutch assembly, comprising:

the compact clutch of any one of claims 1 to 9;

a flywheel; and

a driven disk.
