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. You can also find certified performance values for each product at vbg.eu.

TRADE-OFF DC vs. V

What is a trade-off?

 

 

A component which is only subjected to a horizontal force has a certified performance value for this (Dcert). If the same component is also subjected to vertical forces (rigid drawbar), its performance in the horizontal axis will be reduced. The component will have certified performance values for this situation too (Vcert and Dc-cert).

The performance difference between Dcert and Dc-cert is the ‘trade-off’. This means that a lower V value than the certified value may be permitted, so the component can be used without any risk provided that the calculated V value does not exceed Vlimit.

To drive with this combination, you need a certificate to show that a trade-off is possible and that the coupling equipment provides adequate performance.
