Abstract
In this device, two stacks of discs form at least two sub-assemblies separated by an axially movable intermediate pressure disc, the first of these sub-assemblies being located between the intermediate pressure disc and a stop integral with one of the bodies, whereas the second is located between the intermediate pressure disc and an end pressure disc also axially movable, the control means exerting their action in the direction of the stop, first of all on the two pressure discs so as to cancel out the clearances between the discs of the first sub-assembly, then on the end pressure disc so as to cancel out the clearances between the discs of the second sub-assembly and finally on the whole of the discs of both sub-assemblies so as to compress them. PAC BACKGROUND OF THE INVENTION The present invention relates to multi-disc torque transmission device in oil, of the type comprising a first stack of discs rigidly locked in rotation with a first body and a second stack of discs rigidly locked in rotation with a second body, the discs of the first stack being inserted between the discs of the second and at least one of the two bodies being free to rotate in relation to the other, and c…
