Dual clutch transmission and dual clutch accuators thereof

A dual clutch transmission having multiple gears operatively coupled thereto, the dual clutch transmission comprising:

• a first input shaft and a second input shaft, the first and second input shafts disposed coaxially to each other and operatively coupled with a plurality of gears and at least one output shaft to drive the transmission with a selected one from the plurality of gears;
• a first clutch of generally annular shape, which is operatively coupled with one of the first and second input shafts to drive the transmission with a gear selected from a first set of non-consecutively numbered gears;
• a second clutch of generally annular shape, which is disposed coaxially with the first clutch and operatively coupled with the other one of the first and second input shafts to drive the transmission with a gear selected from a second set of non-consecutively numbered gears;
• a first clutch actuating device and a second clutch actuating device, each of the first and second clutch actuating devices including an actuator and a pivot member, each pivot member of the first and second clutch actuating devices configured to pivotally move about a center of pivot, said each pivot member having a first end operatively coupled to the actuator to pivotally move about the center of pivot and in a direction generally parallel to a coaxial direction of the first and second clutches, and a second end configured to pivotally move about the center of pivot and in a direction generally parallel to the coaxial direction of the first and second clutches and in an opposite direction from the moving direction of the first end as the center of pivot is located between the first end and the second end of the pivot member, the second end operatively coupled to a clutch applicator to move the clutch applicator linearly in the coaxial direction of the first and second clutches, each clutch applicator of the first and second clutch actuating devices having a cylindrical shape, the cylindrically shaped clutch applicator of the first clutch actuating device disposed coaxially with the cylindrically shaped clutch applicator of the second clutch actuating device, such that, as the pivot member of the first and second clutch actuating devices is pivotally moved about the center of pivot, its corresponding clutch applicator is moved linearly in the coaxial direction for clutch operation of the first and second clutches;
• and
• a plurality of first and second clutch levers received in a clutch retaining housing in a circularly arranged pattern, the first clutch levers operatively coupled between the first clutch and the clutch applicator of the first clutch actuating device, the second clutch levers operatively coupled between the second clutch and the clutch applicator of the second clutch actuating device;
• wherein the first clutch levers and the second clutch levers are alternately arranged in the clutch retaining housing such that the first clutch levers and the second clutch levers can operate independently to each other upon movement of the first clutch applicator or the second clutch applicator to perform a selective clutch operation between the first and second clutches.
