Double clutch assembly

A double clutch assembly, comprising:

• a cover casing adapted for receiving a driving force from an engine to rotate;
• a diaphragm spring deformable in an axial direction with respect to the cover casing to induce displacement relative to the cover casing in the axial direction of the cover casing;
• a center plate connected to the cover casing and configured to idle with respect to an input shaft of a transmission;
• an auxiliary cover casing coupled to the center plate to form a support point of the diaphragm spring together with the cover casing;
• a pressure plate selectively connected to the center plate when the diaphragm spring is contracted;
• an auxiliary pressure plate coupled to the center plate and configured to idle with respect to the input shaft of the transmission;
• an auxiliary diaphragm spring deformable in the axial direction with respect to the cover casing;
• a disc installed between the center plate and the pressure plate, the disc comprising a hub to be coupled to the input shaft of the transmission to provide the driving force transmitted through the pressure plate to the input shaft of the transmission;
• an auxiliary disc installed between the center plate and the auxiliary pressure plate, the auxiliary disc comprising an auxiliary hub to be coupled to the input shaft of the transmission to provide the driving force transmitted through the auxiliary pressure plate to the input shaft of the transmission;
• and
• a guide plate non-moveably secured to the auxiliary cover casing and fitted axially into a cutting groove of the diaphragm spring and a cutting groove of the auxiliary diaphragm spring;
• the cutting groove of the diaphragm spring is formed radially from an edge portion towards a central portion thereof;
• the cutting groove of the auxiliary diaphragm spring is formed radially from an edge portion towards a central portion thereof.
