4 Chassis guideline

With the aid of a vehicle guideline system and the defined point of origin, (coordinates zero point), any
point on the vehicle can be clearly identified.
The Body/Equipment Mounting Directives and the 3D data refer to this defined point of origin and the
associated guideline system.

4.1 Guideline system

X-axis: Parallel to roadway in longitudinal direction of the vehicle
with positive direction opposite to direction of travel
Y-axis: Parallel to roadway, lateral to direction of travel
with positive direction towards right side of vehicle
Z-axis: Height axis at right angle to road
with positive direction upwards

4.2 Origin

X=0 Center of the front axle
Y=0 Chassis frame axis of symmetry
Z=0 Center of upper row of bores in longitudinal frame member,
distance to bottom of upper flange: 57.5 mm
Note
Most of the dimensions cited in these Body/Equipment Mounting Directives have been
rounded off; tolerances are not taken into account.
