Patent
CA 2501011
A twin-clutch transmission is provided in which the center distance between input shafts and an auxiliary speed-change shaft can be shortened and the number of gears can be reduced, causing the transmission to be reduced in size and weight. A twin-clutch transmission is provided which includes a first input shaft and a second input shaft, an auxiliary speed- change shaft, and a plurality of gear pairs. The first and second input shaft are connected, through a first clutch C1 and a second clutch C2, respectively, to an input element, and disposed on the same axis. The auxiliary speed-change shaft is disposed parallel to the first and second input shafts. The plurality of gear pairs are provided between the first and second input shafts and the auxiliary speed-change shaft. One of the first and second clutches C1 and C2 is selectively engaged while the other is disengaged, and one of the first and second input shafts that is coupled to the corresponding one of the first and second clutches C1 and C2 is interlocked with the auxiliary speed-change shaft through engagement of a required one of the plurality of gear pairs, thereby achieving a required speed-change ratio. An input path from the input element to the first clutch C1 is different from that to the second clutch C2, and primary ratios of the input paths are set to values, respectively, different from each other.
