2.3 SYSTEM DESCRIPTION, STEERING COLUMN
The height and the tilt angle of the steering
column can be adjusted manually. An 85mm
difference in height can be achieved between
the lowest and highest positions by pulling the
steering wheel upwards. There is a 15_ angle
between the two extreme tilting positions.
A spring-loaded clamping mechanism fixes the
2
steering column in position. An air cylinder
located behind the steering column serves to
release the steering column pneumatically.
Once the steering column has been released, its
movements are cushioned by a gas damper.
The gas damper ensures that the steering
column cannot drop after being released and
that it can easily be pulled upwards.
The control valve (switch) is located on the front
of the steering column. The valve is equipped
with a calibrated vent. Should you forget to
secure the column, this vent ensures that the air
cylinder is bled in approximately 30 seconds.
Such gradual bleeding will take place when the
switch is unloaded. In the top position (convex
shape on switch) the cylinder is being vented,
whereas in the bottom position the cylinder is
being bled rapidly.
