FRONT SUSPENSION
The rebound stroke is illustrated in this drawing. Once the
wheel has overcome the bump, the spring forces the damper
rod to force the piston back through the damper. Here. oil
flows with little resistance into the cylinder, but there is
considerable resistance caused by the damping valve in the
piston.
Resistance resulting from
the passage of oil through
the orifice creates a dampin!
Telescopic Fork:
The telescopic fork serves as a skeletal member of the vehicle
framework, a means for turning the vehicle and as the front
suspension.
When the fork sliders move telescopically on the compression
stroke, oil in Chamber B flows through the orifice in the fork
tube into Chamber C, while the oil in Chamber B pushes past
the free valve and up into Chamber A. The resistance in this oil
flow absorbs shock on compression.
As the fork nears full compression, the tapered oil lock piece
comes into play to hydraulically prevent the fork from
bottoming.
On the rebound stroke, oil in Chamber A flows through the
orifice in the top of the fork piston into Chamber
C.
Here the
resulting resistance serves as a damping force and the tenden-
cy of the spring to rebound quickly is controlled.
The rebound spring absorbs the shock of the.fork legs extend-
ing outward. Oil in Chamber C flows through the orifice in the
bottom of the fork piston into Chamber
B
at this time.
The wheel
encounters
a hole.
