Calculation of the axle load distribution by
measurement on an actual vehicle
W = Gross vehicle weight [kg]
Wf = Total load on the front two axles when the
vehicle is loaded [kg]
Wr = Total load on the rear two axles when the
vehicle is loaded (simultaneous measurement)
[kg]
wf = Total load on the front two axles when the
vehicle is empty (simultaneous measurement)
[kg]
wff = Load on the first front axle when the vehicle is
empty [kg]
wfr = Load on the second front axle when the vehicle
is empty [kg]
wr = Total load on the rear two axles when the
vehicle is empty (simultaneous measurement)
[kg]
= Horizontal distance between the front two axles
when the vehicle is empty [m]
L = Horizontal distance between the center of the
front two axles and the rear axle [m]
p1, p2, p3 ··· pn = Load due to the loaded goods and
occupants [kg]
a1 , a2 , a3 ··· an = Horizontal distance between the
location on which load p1, p2, p3 ··· pn acts and the rear axle [m]
Pf = Load on the front axle due to the loaded goods
and occupants [kg]
/2(wff – wfr)
Wf = wf + + Pf
