Abstract
A power transmission system is provided which can prevent a feeling of inertia travel due to torque transmission interruption occurring when a dog clutch is engaged to shift the speed position, without increasing the axial length of a transmission. An input shaft is connected to a prime mover via a main clutch. Gear pairs are formed by input and output gears arranged on the input shaft and output shafts, respectively. A dog clutch connects one of the gear pairs to the input or output shaft. An auxiliary shaft is connected to the prime mover. Transmission paths are formed on the auxiliary shaft for transmitting the driving force of the prime mover to the output shaft at different gear ratios. In shifting the speed position, an assist clutch supplies the driving force to the output shaft via the auxiliary shaft and a selected transmission path.
