Elastic coupling for internal combustion engine flywheel

摘要

The coupling has a first section (1) surrounding two side discs (1.1,1.2) fixed to the outer circumference. A second section (2) has at least one hub mounted disc positioned between the discs of the first section. Each section has springs (4) to connect them for limited relative rotation. All discs define a fluid sealed chamber. The radially outer area of the chamber has at least one damping fluid filling and a pressure chamber with a throttle opening. The pressure chamber has two first cams (2.3) which are mounted to the coupling section. Second cams (1.5) divide the pressure chamber into two sub chambers (6.1,6.2).
