<p>A dual clutch transmission having two input shafts individually connected to clutches, an intermediate shaft, and an output shaft, wherein the idle of the intermediate shaft in high-speed travel etc. of the vehicle is prevented to avoid excessive stirring of lubricating oil in the transmission and an increase in noise. In the transmission, a direct connection clutch (C3) is provided between one (S2) of the input shafts and an output shaft (S4) and, in addition, an intermediate shaft connection clutch (C4) for permitting and interrupting power transmission is provided between the intermediate shaft (S3) and the output shaft (S4). When power is directly transmitted from the input shaft (S2) to the output shaft (S4) via the direct connection clutch (C3), the intermediate shaft connection clutch (C4) is disconnected to stop rotation of the intermediate shaft (S3), preventing excessive stirring of lubricating oil caused by idle of the intermediate shaft (S3). Also, one gear train is eliminated to reduce the length of the transmission, and this is achieved by forming a transmission stage by disconnecting the intermediate shaft connection clutch (C4) and utilizing the gear train between the two input shafts and the intermediate shaft (S3).</p> |
