<p>The arrangement to oppose difference in relative rotational speed between two rotatable shafts (1, 2) including a primary element, made to rotate with one of the shafts, and a secondary braking element, made to rotate with the other shaft, whereby both sets of braking elements could be changed from a free running position to an engaged position in order to oppose the difference in rotational speed between the two shafts. One of the shafts is carrying a rotatable unit that is showing an angled surface, circular and slightly off 90 degree from the drive shafts. This unit is connected to one side of the braking element and rotating together and sideways movable relatively to the other braking element belonging to the other shaft. Fitted to one of the shafts is a rotatable unit containing a set of movable pistons, relatively running together with the angled surface, in such a way that when a torsional movement takes place at least one of the pistons is pushing back against the fluid system pressure.</p> |
