STOP AND START

In this permanently engaged gear mechanism, the bearing, ERS 1way clutch assembly, and ERS ring gear sub-assembly are positioned between the crankshaft and flywheel sub-assembly, allowing the pinion gear of the starter assembly and the ERS ring gear sub-assembly to be continuously engaged.

When the engine is being started or restarted, the starter assembly starts operating and the ERS ring gear sub-assembly rotates. The inner race of the ERS ring gear sub-assembly pushes the sprags against the outer race, locking the ERS ring gear sub-assembly to the crankshaft, thus turning the crankshaft and starting the engine.

After the engine has started, the crankshaft starts turning faster than the ERS ring gear sub-assembly. When this happens, the sprags of the ERS 1way clutch assembly are released and the ERS ring gear sub-assembly and the crankshaft are unlocked. If the starter stops, the ERS ring gear sub-assembly also stops.
