The D value is a reference value for the horizontal force between truck and trailer.

The coupling equipment you choose must have at least as high a D value as the calculated vehicle combination.

In order to evaluate your combination, you need to enter both the vehicle values and the certified performance values for each component of the coupling equipment.

You can find the certified performance values for the components of the coupling equipment either on the type plate affixed to the component or in the documentation for the component. 

The Dc value is a reference value for the horizontal force between truck and trailer with a rigid drawbar. Here you also need to take into account the vertical forces. The V value is a reference value for the vertical force. This value differs between vehicles with air suspension and those with other types of suspension.

The coupling equipment you choose must have at least as high Dc and V values as the calculated vehicle combination. 

In order to evaluate your combination, you need to enter both the vehicle values and the certified performance values for each component of the coupling equipment.

You can find the certified performance values for the components of the coupling equipment either on the type plate affixed to the component or in the documentation for the component.

The calculation is based on a S-Value of 1000 kg.

The D value is a reference value for the horizontal force between tractor unit and semitrailer.

For this combination, you must consider the maximum kingpin pressure, which may be limited by the total mass of the tractor unit, the max. kingpin pressure on the semitrailer and the max. kingpin pressure on the fixed or adjustable fifth wheel.

The coupling equipment you choose must have at least as high D  values as the calculated vehicle combination. 

The D value is a reference value for the horizontal force between truck and trailer.

D is the reference value for the fifth wheel coupling point.

The Dc value is a reference value for the horizontal force between truck and dolly with a rigid drawbar. Here you also need to take into account the vertical forces. The V value is a reference value for the vertical force. 

For a dolly with rigid drawbar, the Dc and V values for the chosen coupling equipment must exceed the calculated values. For a dolly with hinged drawbar, the D value for the coupling equipment must exceed the calculated Dc value for the dolly.
