ABSTRACT:
The torsional vibration damper has annular cover and side discs which are connected with one another in sealed manner in the region of their external circumference and are sealed off in the region of their internal circumference through annular discs movably in relation to a hub disc arranged between these discs. The closed annular space thus produced contains lubricant to reduce wear in the springs which rotationally elastically couple the components of the torsional vibration damper. At least one of the cover or side discs is made axially elastic. Resilient members are provided which clamp the hub disc in between the sealing friction discs and ensure a defined friction torque dimensioned especially for idling operation.
