d) 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 shocks are transmitted from the wheels into the steering mechanics during operation, they are not immediately
transmitted to the steering servo, but are absorbed by the resilient connection of the two lever arms of the servo saver.
The effect of the servo saver can be adjusted with a
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.
