c) Setting the camber
The camber is the inclination of the wheels to the perpendicular.
Negative camber
Positive camber
(wheel top edges point inwards) (wheel top edges point outwards)
A negative camber at the front wheels increases the cornering forces of the wheel when driving in bends, the steering responds more directly, the steering forces
are reduced. At the same time the wheel is pushed onto the axle leg in the direction of the axis. This disables axial bearing clearance, the driving behaviour is
calmer.
A negative camber at the rear wheels reduces the tendency of the rear of the vehicle to swerve in curves. By setting a negative camber, the wear on the inside
of the tires increases. However, this effect can be compensated by setting a toe-in.
Setting a positive camber reduces the cornering forces of the wheels!
Setting the camber at front and rear wheels
Die straining screws used to fine-tune the camber are located at the upper control arms.
• Turn the straining screw in the upper control arm clockwise: The wheel top edge is pulled inwards
towards a "negative camber".
• Turn the straining screw in the upper control arm anti-clockwise: The wheel top edge is pulled
outwards towards a "positive camber".
Make sure the settings for the cornering forces of the front and the rear axle are well-balanced,
as differences can cause "oversteering" or "understeering" driving behaviour.
d) Setting the track
The track designates the position of the wheel level to the driving direction.
When driving, the tyres are pushed apart at the front because of the rolling friction and are therefore no longer exactly parallel to the driving direction. To
compensate this, the tyres can be adjusted (when the vehicle is not moving) so that they point slightly inwards. This toe-in improves the cornering of the tyre and
thus results in a more direct control of the steering.
If a softer steering response is desired, the toe-out can be adjusted accordingly, i.e. the wheels of the vehicle point outward (when it is not moving).
For a rough adjustment of the track, the outer steering links can be screwed to two additional attachment points on the steering plate. This also changes the
Ackermann steer angle. Straining screws (see ill. below, right, pos. 1) for separate alignment of the front wheels are located in the right and left steering link
between the steering lever and the steering plate.
The toe-in of the front wheels must not exceed 4°!
Toe-in (a):
Turning the straining screws (1) forward lengthens
the outer steering link, the wheel is pushed outwards
via the steering knuckle arm at the back. With this
setting, the wheels wear off a lot faster on the inside.
Toe-out (b):
Turning the straining screws (1) backward shortens
the outer steering link, the wheel is pulled inwards
via the steering knuckle arm at the back. With this
setting, the wheels wear off a lot faster on the outside.
