Abstract
A power transmission system capable of preventing a feeling of inertia travel caused by torque transmission interruption, without increasing the axial length of a transmission, thereby improving the speed position-shifting performance of the transmission, includes a plurality of gear pairs and synchromeshes connecting the plurality of gear pairs to an input or output shaft. A driving force assist mechanism supplies the driving force of a prime mover to the output shaft during a shift in speed position and a supplemental driving force has an auxiliary shaft arranged in parallel with the input and output shaft. An intermediate gear is connected to the input shaft and integrally formed with the auxiliary shaft. Auxiliary gears are connected to the output shaft and rotatably arranged on the auxiliary shaft. An assist clutch fastens one of the auxiliary gears to the auxiliary shaft during the shift in speed position.
