Torsional vibration damper

摘要

The invention relates to a torsional vibration damper in which, under the action of axially elastic spring elements on the coupling members between the damper halves, relative rotations of the damper halves lead to an axial extension of the coupling members. The spring elements are designed as axially elastic diaphragm discs which also transmit torques between the damper halves, making possible the construction of simple and economical torsional vibration dampers composed of a small number of individual components. The torsional vibration damper operates in a jerk-free manner and is virtually wear-free because, due to the use in its construction of diaphragm discs which act on rolling elements, only small frictional forces occur. In the case of use of the torsional vibration damper in a clutch, transmission of large torques with large angles of rotation is possible for a small clutch diameter. By the formation of chambers filled with damping fluid adjoining the diaphragm discs, damping of the rotary motions of the damper parts based on displacement of fluid can be achieved in a simple manner. <IMAGE>
