e) Setting the Servo Saver
The steering of the vehicle is designed as an axle leg
steering.
The pivoting movement of the servo control lever (A) has
A
an effect on the steering linkage (B) and on one arm (C)
E
C
of the servo saver.
B
The servo saver consists of two right-angled levers (C and
D
D), which are not rigidly coupled but can be moved against
each other via a spring on one level with the steering lin-
G
kage.
F
The second lever arm of the servo saver (D) moves the
steering plate (E) which in turn causes the steering deflec-
tion of the front wheels via the two track rods (F).
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 lever arms (C and
D) of the servo saver.
The effect of the servo saver can be adjusted with a knurled nut (G) 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.
f) Mechanical Lowering
For lowering the chassis, it is also possible to reduce the
rebound clearance mechanically. There is a small adjus-
table grub screw in each of the 4 transverse links for this;
see circle in the figure on the right.
When the grub screw is turned in further, the transverse
link cannot extend as far anymore; this lowers the chas-
sis.
