ABSTRACT:
An elastic coupling, particularly for a multi-mass flywheel in the drive train of a motor vehicle drive. The elastic coupling has three masses which are connected to each other in each case by spring elements, a damping device being connected in parallel with each spring element. The damping device between the first and the second masses includes radially extending projections on the second mass which exert either a circumferential force on the first springs or a damping force in an adjacent fluid displacement chamber. The side walls of the fluid displacement chambers simultaneously serve as retaining shoulders for the springs in the adjacent spring chambers whereby the projections can carry out the above-mentioned dual functions. A great advantage of this arrangement is a particularly advantageous space-spacing arrangement of the damping device in the radially outer region of the elastic coupling.
