Dual clutch type automated transmission apparatus

A dual clutch type automated transmission apparatus, comprising:

• a first input shaft;
• a second input shaft provided for rotating independently from a rotation of the first input shaft;
• an output shaft;
• a dual clutch mechanism comprising:
• a first clutch portion connected to the first input shaft;
• a first clutch actuator for operating the first clutch portion for establishing and interrupting a first torque transmitting path between the first input shaft and the output shaft;
• a second clutch portion connected to the second input shaft;
• and
• a second clutch actuator for operating the second clutch portion for establishing and interrupting a second torque transmitting path between the second input shaft and the output shaft;
• the dual clutch mechanism selectively establishing and interrupting the first torque transmitting path between the first input shaft and the output shaft and the second torque transmitting path between the second input shaft and the output shaft;
• a plurality of first gear trains for selectively connecting and disconnecting the first and second input shafts to and from the output shaft for transmitting a torque transmitted from the first and second input shafts to the output shaft at a different speed ratio;
• a plurality of first connecting portions provided at the plurality of first gear trains for selectively connecting and disconnecting the first and second input shafts to and from the output shaft (5) via one of the plurality of first gear trains;
• a second gear train provided between the first input shaft and the output shaft for transmitting the torque transmitted from the first input shaft to the output shaft;
• a second connecting portion provided at the second gear train and connected to the second clutch actuator, the second connecting portion operated by the second clutch actuator to connect and disconnect the first input shaft to and from the output shaft via the second gear train when the second clutch actuator operates the second clutch portion to interrupt the second torque transmitting path between the second input shaft and the output shaft.
