D-value Truck and trailer

Truck and trailer: D-value

• Theoretical horizontal force between towing vehicle and trailer
• The D-value can only be calculated with the permissible total weight of both truck and trailer
• Calculation of the D-value (kN):

D(kN) = (g * T * R) / (T + R)

The calculated D-value can be equal to or lower than the D-value of the hitch and of the towing eye.

T =
R =

total weight of the towing vehicle in t

total weight of the drawbar trailer in t
