Abstract

An operation mechanism for a dual-clutch assembly is provided. The dual-clutch assembly comprises a first clutch having a first clutch bearing, and a second clutch having a second clutch bearing. The operation mechanism comprises: a supporting member; a first operation member adapted to be rotatably coupled to the supporting member and to actuate the first clutch bearing; and a second operation member adapted to be rotatably coupled to the supporting member and to actuate the second clutch bearing. The second operation member is always spaced a predetermined distance from the first operation member in an operation direction.

First claim

What is claimed is:

1. An operation mechanism for a dual-clutch assembly, the dual-clutch assembly comprising a first clutch having a first clutch bearing, and a second clutch having a second clutch bearing, the operation mechanism comprising:
a supporting member;
a first operation member adapted to be rotatably coupled to the supporting member and to actuate the first clutch bearing; and
a second operation member adapted to be rotatably coupled to the supporting member and to actuate the second clutch bearing, the second operation member being always spaced a predetermined distance from the first operation member by the supporting member in an operation direction of the dual-clutch assembly,
wherein the first operation member has a first predefined operation range along the operation direction of the dual-clutch assembly and the second operation member has a second predefined operation range along the operation direction of the dual-clutch assembly and there is no overlap between the first predefined operation range and the second predefined operation range; and
wherein neither of the first operation member and the second operation member is positioned inside the other operation member.

2. The operation mechanism according to claim 1 , wherein the first operation member is always spaced the predetermined distance from the second operation member in an axial direction of the supporting member.

3. The operation mechanism according to claim 1 , wherein the first clutch bearing comprises a first bearing element, and the first operation member comprises a first bearing area configured to contact the first bearing element, and
wherein the second bearing comprises a second bearing element, and the second operation member comprises a second bearing area configured to contact the second bearing element.

4. The operation mechanism according to claim 1 , wherein the supporting member comprises first and second supporting elements coupled to each other and having different heights from each other,
wherein the first supporting element comprises a first positioning portion, and the first operation member comprises a first rotation portion rotatably coupled to the first positioning portion; and
wherein the second supporting element comprises a second positioning portion, and the second operation member comprises a second rotation portion configured to be rotatably coupled to the second rotation portion.

5. The operation mechanism according to claim 4 , wherein the first operation member comprises a first guide groove formed at an end of the first operation member opposite the first rotation portion.

6. The operation mechanism according to claim 4 , wherein the second operation member comprises a second guide groove formed at an end of the second operation member opposite the second rotation portion.

7. The operation mechanism according to claim 1 , wherein the first operation member comprises a reinforcing structure.

8. The operation mechanism according to claim 7 , wherein the reinforcing structure is configured with a reinforcing rib.

9. The operation mechanism according to claim 1 , wherein the second operation member comprises an arc transitional structure.

10. A dual-clutch assembly comprising the operation mechanism according to claim 1 .

11. A vehicle comprising the dual-clutch assembly according to claim 10 .
