b) Setting the Alignment
Wheel alignment (toe-in = figure „A“, toe-out = figure „B“) describes
the relation of the wheel level to the driving direction.
While driving, the tyres are pushed apart in the front because of the
rolling friction. This is why they are no longer precisely parallel to the
driving direction.
To compensate, the tyres of the stationary vehicle can be adjusted so
that they point slightly inwards. This toe-in improves lateral cornering
of the tyres and leads to a more direct response to steering.
If a milder response to steering is desired, this can be achieved
accordingly by adjusting a toe-out, i.e. the wheels of the stationary
vehicle point outward.
An alignment angle of more than 3° toe-in (A) or toe-out (B) will lead to handling problems and decreased
speed. It will also increase tyre wear.
The figure above shows a strongly over-emphasised setting. It is only used for showing the difference
between toe-in and toe-out. If such a setting is used for the vehicle, it will be very difficult to control!
Setting front axle alignment:
For the front axle, alignment can be set by twisting the
steering knuckle arm (A). Because it has a left and right
hand thread each, it does not need to be dismantled to
be adjusted.
Turn both track rod levers evenly (left and right front wheel).
Otherwise, you need to adjust the trim of the transmitter (or
even change the steering servo control by adjusting the
servo rod).
At the linkage angle (B) and in the axle stub (C) there are
several attachment points for the steering knuckle arm,
which are used for changing the turning angle of the front
wheel (Ackermann angle).
The manufacturer already selected the best setting. Therefore, you should not change these attachment points (B)
and (C).
Setting rear axle alignment:
The track of the rear axle in this vehicle is set and cannot be changed.
