Weight distribution
To meet customer needs and ensure the smooth operation of the vehicle and its du
-
rability, when building a body to join a particular chassis, proper weight distribution
of the whole vehicle should be ensured, so that the maximum allowable load capac
-
ity of the axles can be utilised. Always take legal requirements and the technical ca
-
pabilities of each vehicle into account.
The ultimate goal is to achieve the best possible location of the body on the chassis.
For this purpose, the following guidelines should apply:
Unilateral axle load:
When the body is planned and designed, unilateral load situations should be avoided.
The maximum load difference between the wheels on the same axle must never ex
-
ceed 4 %, in order to avoid the inclination of the vehicle to one side. This difference
will always be applied to the actual axle load, not to the admissible axle load.
