Click to enlargeDue to the design with piston pumps, the reaction at start is instant. The diagram shows a max. acceleration from still stand -after 150 ms the slip on the driving wheels is completely stopped.

Deactivation on ABS signal
Click to enlargeThe diagram shows the pressure drop in the coupling when the ABS system is activated. The pressure, and thus the torque, decreases within 60 ms. Green curve: Brake activation Yellow curve: ABS activation Purple curve: Coupling pressure (base pressure is 4 bar).

Activation of Over-load protection valve function
The diagram shows the torque transfer in a coupling where the torque limitation is set to 1000 Nm. When max. torque is reached, the over-load protection valve opens and the torque is maintained at the pre-set value.
