A dual clutch transmission comprises a first set of input gears 206, 207, 208, 209 each of which meshes with one of a first set output gears 220, 221, 222, 223 a second set of input gears 210, 211, 212, 213 each of which meshes with a respective one of a second set of output gears 224, 225, 226, 227. A first clutch 215 is associated with the input gears 206, 207, 208, 209 and a second clutch 216 is associated with the input gears 210, 211, 212, 213 and the output gears 210, 211, 212, 213. At least one of the input and output gears can freely rotate on a shaft and a gear ratio selection mechanism 231 selects a gear ratio by locking the gear to the shaft. In use either the first clutch 215 is engaged and the second clutch 216 disengaged and drive is transmitted via a selected pair of the first set of input and output gears or the second clutch 216 is engaged and the first clutch 215 disengaged and drive is transmitted via a selected pair of the second set of input and output gears. |
