PROBLEM TO BE SOLVED: To provide a compactly constituted parallel shaft type transmission, by reducing the number of wet multiple disc clutches, by reducing the size in the axial direction as compared with the number of shift stages. SOLUTION: A first idle driving passage and a second idle driving passage are arranged for transmitting rotation of an input shaft to an intermediate shaft. The first idle driving passage includes a one-way clutch capable of transmitting input shaft side rotation only to the intermediate shaft side. The second idle driving passage includes the wet multiple disc clutch for connecting a gear rotatably installed on the intermediate shaft to the intermediate shaft. Thus, the intermediate shaft is rotated at a first rotating speed via the first idle driving passage, and is rotated at a second rotating speed faster than the first rotating speed via the second idle driving passage when engaging the clutch. Thus, the number of shift stages more by one than the number of wet multiple disc clutches can be provided. COPYRIGHT: (C)2008,JPO&INPIT |
