ABSTRACT:
The disclosure concerns an elastic coupling of disc construction. The coupling has a central disc which is positioned within an inner chamber that is defined by two side discs, and the side discs are joined together at their peripheries. The discs are attached at a hub at their axes. The side discs are of greater circumference than the central disc. A projection extending in from the side discs toward the central disc has circumferentially opposite abutment surface sides. In the central disc, a recess is defined into which the aforesaid projection extends. The recess has opposed abutment surface sidewalls, and each of these abutment surface sidewalls is opposed to a respective abutment surface side on the projection. The resulting pair of displacement chambers defined by the abutment surfaces on the projection and the cooperating abutment surfaces on the central disc are connected by a throttle opening, whereby as one displacement chamber enlarges as the central disc and the side discs rotate with respect to each other, the other displacement chamber correspondingly decreases in volume and fluid will move between the displacement chambers, thereby damping the relative rotation of the discs. There are elastic coupling elements or springs joining the central and side discs. The central disc has a through port that receives the springs of the elastic coupling elements and the side discs have recesses in which the springs are also supported.
