f) Setting the Servo Saver
The steering of the vehicle is designed as an axle leg steering.
The pivoting movement of the servo control lever affects one arm of the servo saver via the steering linkage.
The servo saver consists of two right-angled levers, which are not rigidly coupled but can be moved against each other
with a spring in one level with the steering linkage.
The second lever arm of the servo saver moves the steering plate which in turn causes the steering deflection of both
front wheels via the two track rods.
When hard impacts are transmitted through the steering mechanics during operation, they are not immediately trans-
mitted to the steering servo, but are absorbed with the help of the resilient connection of the two steering levers of
the servo saver.
The effect of the servo saver can be adjusted with a knurled nut
(A) by modifying the spring contact pressure on the two lever
arms.
When this is set too soft, even light impacts against the wheel will cause the two servo saver arms to twist,
which will negatively influence steering accuracy and track during driving.
However, if it is set too tightly, the servo drive may be damaged because impacts against the wheels are
passed on to the wheels unfiltered.
The manufacturer has already selected the best setting for the servo saver. Adjustment therefore usually is
not required.
