Abstract:
A starter system for an internal combustion engine, for starting the engine by driving a crankshaft for rotation,the starter system comprising: a hydraulic actuator that is driven by hydraulic pressure; a first rotational shaft that is driven for rotation by said hydraulic actuator; an electric motor; a second rotational shaft that extends in parallel with said first rotational shaft and is driven for rotation by said electric motor; a driven gear that rotates in unison with the crankshaft; a driving gear that is brought into meshing engagement with said driven gear when the engine is started; a third rotational shaft that is connected to said driving gear; a first driving force-transmitting mechanism that connects said first rotational shaft and said third rotational shaft to each other in a disconnectable manner, for transmitting rotation of said first rotational shaft to said third rotational shaft; and a second driving force-transmitting mechanism that connects said second rotational shaft and said third rotational shaft to each other in a disconnectable manner, for transmitting rotation of said second rotational shaft to said third rotational shaft.
