Abstract
A disk-type flexible coupling, specifically for installation into the drive train of a motor vehicle between a combustion engine and a transmission, has a first coupling half. The first coupling half, by use of two side disks which are connected for torsional strength on the outer circumference, encloses a second clutch half which is formed by at least one center disk which is assigned to one hub. The coupling halves are interconnected through flexible coupling elements and have limited torsion relative to each other. The side disks border a liquid-tight inside chamber which is filled with a damping medium and which receives the center disk. In the inside chamber, a floating damping ring is provided which has limited torsion relative to the two coupling halves. The damping ring, together with the first coupling half, forms a first displacement chamber. The damping ring, together with the second coupling half, forms at least one second displacement chamber. The volume of both displacement chambers is variable. The first and second displacement chambers are connected conductively.
