Setting The Shock Absorbers - Reely ROAD Promotion 30 Notice De Montage

b) Setting the shock absorbers
The spring elements of the all-wheel suspension of the chassis consist each of a coil spring (1) in whose
center an oil dampened suspension () is located.
The oil-dampened shock absorbers are mounted on the lower transverse links and at the top on the
damper plate on the differential housings. On the top, the coil springs rest against a screw ring (3) on
the outer tube of the shock absorber and a plate on the bottom end of the piston rod.

Turning the screw ring towards the top relieves the spring. Turning it downward increases the spring
preload. The spring preload can thus be finely adjusted according to surface and manner of driving.
A steeper angle of attack (just as a higher spring preload) causes a higher pressure on the lower
transverse links, whereby the chassis is slightly lifted.
A flater angle of attack (or a lower spring preload) causes the chassis to sink deeper under its own weight. In this way a higher/lower setting of the chassis
can be achieved (setting ground clearance).
The setting of the suspension influences not only the ability of the model to "even out" road unevenness, but also the behavior in bends.
This driving behavior is called to "oversteer" or to "understeer".
Understeering driving behavior:
The model is difficult to steer around the bend, "pushes" the front wheels outwards (too much traction of the
rear axle or too little traction of the steered front axle.
As a counter measure the suspension should be set harder at the rear (or softer at the front).
Over-steering driving behavior
The model "pulls" in the bend, the rear tends to swerve (too little traction on the rear axle or too much traction at the steered front axle).
As a counter measure the suspension should be set softer at the rear (or harder at the front).
Over-steering or under-steering driving behaviour can be the result of uneven cornering powers of front and rear axle due to incorrect setting of the cam-
ber.
As a basic setting, the front axle should be set approximately 5 mm lower than the rear axle!
Check the impact of the shock absorbers:
•
Lift the model at the rear axle and drop it.
•
The model should not deflect until lock and only top out once without any reverberation!
•
Test the shock absorbers of the front axle in the same way.
Changing shock absorbers (at the lower suspension)
•
Moving the lower transverse link towards the inside (steep angle of attack) reduces the progressivi-
ty. After a little deflection the suspension is already harder. At the same time the vehicle is brought
in a higher position.
•
Moving towards the outside (shallow angle of attack) increases the progressivity, the suspension
reacts softer and becomes harder with increasing deflection. The position of the vehicle is lowered.
In the case of a shallow angle of attack, the chassis has a deeper spring deflection so that the
suspension reacts.
Setting the spring preload
•
Increasing the spring preload
•
Turn the screw ring on the outer tube of the shock absorber clockwise.
•
Decreasing the spring preload
•
Turn the screw ring on the outer tube of the shock absorber anticlockwise.
The spring preload and the fixing points of the shock absorbers of one axle have to be
adjusted identically on the right and left!
