- Shock Absorbers
-
- Direct,
- double-acting
- hydraulic shock
- absorbers and shock
- struts are the most
- common type of
- shock absorbing
- device in use
- today.
-
- Direct hydraulic
- shock absorbers
- work by forcing
- fluid through a
- small opening,
- called a
- "restriction".
- Restricting the
- fluid flow slows
- the rapid up and
- down movement of
- the wheels as they
- move over road
- irregularities.
-
- Hydraulic shock
- absorbers
- automatically
- adjust their
- resistance to
- movement. When a
- wheel moves upward
- slowly, resistance
- is light. During
- rapid or violent
- movement, the
- resistance is
- greater because the
- fluid is forced
- through the same
- opening at a higher
- rate.
- Double-acting units
- are built to be
- effective in both
- directions because
- spring rebound can
- be as violent as
- the original bump.
-
- This system of
- shock absorber
- aided suspension
- delivers a soft
- ride over small
- bumps and controls
- spring bounce over
- large bumps.
