Abstract

A double clutch assembly includes: a center plate, first and second disks, first and second pressure plates, a connecting plate, a cover plate, a pulling cover, first and second diaphragm springs, and a guide plate. In particular, the pulling cover is formed with an engagement recess, an engagement slot is formed at the second diaphragm spring, and the guide plate includes a body, an exterior engagement end protruding toward the second diaphragm spring and inserted into the engagement slot and the engagement recess, an interior engagement end formed at an interior circumference of the body, and a fixing end inserted into an incision slit of the second diaphragm spring.

First claim

What is claimed is:

1. A double clutch assembly, comprising:
a center plate;
first and second disks disposed at opposite sides of the center plate, respectively;
a first pressure plate disposed at a distal side of the first disk;
a second pressure plate disposed at a distal side of the second disk;
a connecting plate disposed at a distal side of the second pressure plate and configured to receive an engine torque;
a cover plate disposed at a distal side of the first pressure plate and fixedly coupled with the center plate;
a pulling cover disposed at a distal side of the cover plate and connected with the second pressure plate;
a first diaphragm spring disposed between the first pressure plate and the cover plate and configured to introduce an axial direction displacement to the first pressure plate;
a second diaphragm spring disposed between the cover plate and the pulling cover and configured to introduce an axial direction displacement of the cover plate; and
a guide plate fixedly coupled to the cover plate and configured to guide the second diaphragm spring in an axial direction,
wherein the pulling cover is formed in a disc shape and is formed with a plurality of engagement recesses at an interior circumference portion of the pulling cover,
wherein a plurality of engagement slots are formed along an exterior circumference of the second diaphragm spring, and
wherein the guide plate comprises:
a body having a ring shape;
a plurality of exterior engagement ends formed at an exterior circumference of the body and protruding toward the second diaphragm spring to be inserted into the plurality of engagement slots and the plurality of engagement recesses;
a plurality of interior engagement ends formed at an interior circumference of the body; and
a plurality of fixing ends each protruding from the interior circumference of the body between adjacent interior engagement ends and inserted into an incision slit of the second diaphragm spring.

2. The double clutch assembly of claim 1 , wherein the guide plate further comprises a protrusion end having a ring shape and configured to: protrude toward the second diaphragm spring and form a contact point with the second diaphragm spring.

3. The double clutch assembly of claim 1 , wherein the pulling cover is formed with a second supporting end configured to: protrude toward the second diaphragm spring and support a surface of the second diaphragm spring, thereby forming a second pivot point at which the second diaphragm spring pivotally operates with respect to the pulling cover.

4. The double clutch assembly of claim 1 , wherein the plurality of engagement recesses are formed by a predetermined depth in a radial direction such that the interior circumference portion of the pulling cover is configured to form a curved line.

5. The double clutch assembly of claim 1 , wherein each engagement slot of the plurality of engagement slots is formed as a slot formed in parallel with the exterior circumference of the second diaphragm spring and having an open end to the exterior circumference of the second diaphragm spring.

6. The double clutch assembly of claim 1 , wherein each interior engagement end of the plurality of interior engagement ends of the guide plate is formed with a pin hole to be engaged with the cover plate.

7. The double clutch assembly of claim 1 , wherein each fixing end of the plurality of fixing ends is formed with two wing portions to be fitted to the incision slit of the second diaphragm.

8. A double clutch assembly, comprising:
a center plate;
first and second disks disposed at opposite sides of the center plate, respectively;
first and second pressure plates disposed at distal sides of the first and second disks, respectively;
a connecting plate disposed at a distal side of the second pressure plate and configured to receive an engine torque;
a cover plate disposed at a distal side of the first pressure plate and fixedly coupled with the center plate;
a pulling cover disposed at a distal side of the cover plate and connected with the second pressure plate;
a first diaphragm spring configured to introduce an axial direction displacement to the first pressure plate;
a second diaphragm spring configured to introduce an axial direction displacement to the second pressure plate; and
a guide plate disposed between the cover plate and the second diaphragm spring,
wherein the guide plate comprises:
a body formed in a ring shape;
a plurality of exterior engagement ends formed at an exterior circumference of the body and protruding toward the second diaphragm spring to be inserted into a plurality of engagement slots formed at an exterior circumference of the second diaphragm spring and to be inserted into a plurality of engagement recesses formed at an interior circumference of the pulling cover;
a plurality of interior engagement ends each formed at an interior circumference of the body and having a pin hole to be engaged with the cover plate by an engagement pin;
a plurality of fixing ends each protruding from the interior circumference of the body between adjacent interior engagement ends and inserted into an incision slit of the second diaphragm spring; and
a protrusion end of a ring shape protruding toward the second diaphragm spring and forming a contact point with the second diaphragm spring.

9. The double clutch assembly of claim 8 , wherein each fixing end of the plurality of fixing ends comprises two wing portions to be fitted to the incision slit.

10. The double clutch assembly of claim 8 , wherein the pulling cover is formed in a disc shape and is formed with a plurality of engagement recesses at an interior circumference portion of the pulling cover by a predetermined depth in a radial direction such that the interior circumference portion of the pulling cover is configured to form a curved line.

11. The double clutch assembly of claim 8 , wherein the pulling cover is formed with a second supporting end protruding toward the second diaphragm spring and supporting a surface of the second diaphragm spring, thereby forming a second pivot point at which the second diaphragm spring pivotally operates with respect to the pulling cover.

12. The double clutch assembly of claim 8 , wherein each engagement slot of the plurality of engagement slots of the second diaphragm spring is formed as a slot formed in parallel with the exterior circumference of the second diaphragm spring and having an open end to the exterior circumference of the second diaphragm spring.
