Patent ID: 7661331

Claim:
A shifting device for a dual clutch transmission, the dual clutch transmission including a first input shaft, a second input shaft, and a counter shaft arranged in parallel with one another, a dual clutch including a first clutch for transmitting rotation of a drive shaft that is driven to rotate by a power source to the first input shaft and a second clutch for transmitting rotation of the drive shaft to the second input shaft, a first gear change mechanism including at least a first gear train provided between the first input shaft and the counter shaft and a first switching clutch for selecting a power transmission performed by the first gear train, and a second gear change mechanism including at least a second gear train provided between the second input shaft and the counter shaft and a second switching clutch for selecting a power transmission performed by the second gear train, the shifting device comprising: a shift mechanism operating the first and second switching clutches and including a first shifter that includes a first follower pin and a first shift fork engaging with a switching member provided at the first switching clutch, the first shifter being slidably arranged in parallel with the first input shaft and the counter shaft; the shift mechanism including a second shifter that includes a second follower pin and a second shift fork engaging with a switching member provided at the second switching clutch, the second shifter being slidably arranged in parallel with the second input shaft and the counter shaft; the shift mechanism including a cam member driven by a motor to rotate and at which a single cam groove is formed, the cam groove passing through a position away from a rotational center of the cam member; and the first and second follower pins engaging with different positions on the cam groove from each other and operating the first and second switching clutches to be associated with each other.
