VIBRATION ISOLATION STRUCTURE OF POWER UNIT INCLUDING TORQUE DAMPERS

摘要

A vibration isolation structure of a power unit in which an internal combustion engine is provided with transmissions, including plural transmission gears and a power transmission shaft that pivotally supports the plural transmission gears, and torque dampers are provided between a pair of adjacent transmission gears and the power transmission shaft. The vibration isolation structure can suppress torque fluctuation itself accompanying gearshift and driving reaction force to small fluctuation, and reduce the size of the power unit.
