C) Setting The Camber; D) Setting The Wheel Alignment - Reely ROAD Predator XL Operating Instructions Manual

c) Setting the camber

The camber is the inclination of the wheels to the perpendicular.
Negative camber
(wheel top edges point inwards)
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 bends. 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 transverse links.
• Turn the straining screw in the upper transverse link clockwise: The wheel top edge is pulled
inwards towards a "negative camber".
• Turn the straining screw in the upper transverse link 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 wheel alignment

The wheel alignment 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). A toe angle
of 0° at the front axle ensures the best driveability on almost any ground.
A toe angle of more than 3° toe-in or toe-out leads to handling problems and reduces the speed.
For a rough adjustment of the alignment, the outer steering links can be screwed to two additional attachment points (2) on the steering plate. This also changes
the Ackermann steer angle. Straining screws (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.
