SYSTEMS OPERATION
The damperconsists essentially ofsix coil springs
1 and two friction plates 2. Its hub is splined to
the shaft and one of the friction plates is bolted to
flywheel 3.
The combination of coil springs and friction
plates absorbs power impulse from the engine
which would otherwise be transmitted directly to
the gears in the transmission as when the engine
is quickly accelerated or decelerated and shocks
from the ground through power train.
