ABSTRACT:
A twin-clutch-type transmission which can suitably change a power transmitting route, corresponding to the gear shifting conditions, without requiring complex a control, includes a first clutch mechanism, a second clutch mechanism, a first gear mechanism connected to the first output member of the first clutch mechanism, a second gear mechanism connected to the second output member of the second clutch mechanism, a control device, and an interlocking member.
The first clutch mechanism includes an input member, a first output member, a first pressure plate and a first thrust means which engages the first output member to the input member through the first pressure plate. The second clutch mechanism includes an input member, a second output member, a second pressure plate and a second thrust means which engages the second output member to the input member through the second pressure plate.
The first gear mechanism has gear sets to provide a first group of gear ratios, a second gear mechanism connected to the second output member of the second clutch mechanism. The second gear mechanism has gear sets to provide a second group of gear ratios. The control device controls thrust forces generated by the thrust means so as to change one of the two clutch mechanisms from an engaged condition to a disengaged condition and to change the other of the two clutch mechanism from a disengaged condition to an engaged condition. The interlocking member mechanically interlocks the first pressure plate of the first clutch mechanism and the second pressure plate of the second clutch mechanism.
