c) Setting of the Camber
The camber is the inclination of the wheel level as viewed from the front (vertical).
Negative inclination
(Top wheel edge points inwards)
A negative inclination on the front wheels increases the lateral cornering powers of the wheel when driving through bends, the steering reacts more directly and
steering forces are reduced. At the same time the wheel is pushed onto the axle leg in the direction of the axis. This stops an axial bearing clearance, the driving
behaviour is calmer.
A negative inclination on the rear wheels reduces the tendency of the rear of the vehicle to swerve in bends. By setting a negative inclination, the wear on the
inside of the tires increases. However, this effect can be compensated by setting a toe-in.
Shifting the camber in positive direction up to a positive camber, however, reduces the side tracking power of the wheels!
Setting of the camber on front and rear wheels
The clamping screws for fine adjustment of the camber are each located in the top transverse control arms.
• Turn the clamping screw in the upper control arm clockwise: The wheel top edge is pulled inwards towards a "nega-
tive camber".
• Twist the clamping screw in the upper transverse link counter-clockwise: The wheel top edge is pulled outwards
towards a "positive camber".
Ensure a balanced adjustment of the lateral track forces of the front and rear axis, because differences may lead to
oversteering/understeering.
d) Setting the Alignment
This alignment designates the position of the wheel level to the driving direction.
During the drive the tyres are pushed apart in the front because of the rolling friction and this is why they are no longer precisely parallel to the driving direction.
To balance this, the tyres of the stationary vehicle can be adjusted in a way so that they point slightly towards the inside. This toe-in improves the lateral
cornering of the tire and thus a more direct response to the 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. A trail
angle of 0° on the front axis ensures the best driveability on almost any ground.
A trail angle of more than 3° toe-in or toe-out leads to handling problems and reduces the speed.
For a rough setting of the alignment, you can screw the outer track rods
on the steering plate onto two additional attachment spots (2). This also
changes the Ackermann angle. Clamping screws (1) for separate wheel
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 wheel must not exceed 4°!
Toe-in (a):
Turning the clamping screws (1) towards the front lengthens the outer steering link; the wheel is pulled outwards
via the steering knuckle arm on the back. This setting leads to faster wear on the inside of the tyres.
Toe-out (b):
Turning the clamping screws (1) towards the back shortens the outer steering link, the wheel is pulled inwards
via the steering knuckle arm on the back. This setting leads to faster wear on the outside of the tyres.
