2) Overrunning Clutch
The overrunning clutch prevents the armature from
being driven by the rotational force of the engine when
the pinion and the engine flywheel ring gear are in mesh.
1. When power is transmitted, the rotational force of the
outer clutch gear (1) drives the pinion gear (6)
through the roller (2).
2. Even when the pinion gear is driven by the engine
flywheel ring gear and its speed exceeds that of the
outer clutch gear, the rotation force of the ring gear
is not transmitted to the outer clutch gear.
