Steering System
Components
Antijerk Valves
Description
Antijerk Valves provide
smoother steering on
articulated vehicles, such as
Wheel Loaders. This is
achieved by a pressure
sequence valve mounted on
a block. Patent pending.
(For more information see
Vickers
® Screw-in Cartridge
Valves Cat. V-VLOV-MC001-E2.)
Features
Dramatically reduces jerk
when steering is stopped
quickly and while making
aggressive changes in
direction. The valve works by
monitoring the margin
pressure acting on the
steering valve. Margin
spikes when steering wheel
speed is reduced
aggressively. When this
occurs a small amount of
damping flow is allowed
across the turn ports. Unlike
accumulators this valve will
not have a negative affect on
roading performance, and it
is more cost effective than
cushion valves.
Applications
CF1 is supply from the
pump or priority valve, CF2
should connect to the
steering valve UPSTREAM
of any check valves, LS1 &
LS2 are the steering valve
load-sense connection, R&L
are pass through ports for
the turn lines. The setting of
the valve needs to be higher
than the normal difference in
pressures between CF and
LS, i.e. if CF-LS is 150PSI
then a good setting to start
with is 200PSI.
