Patent ID: 7025681

Claim:
A drive train comprising a torsional vibration damper and a torsionally flexible coupling assembled into a modular unit with a common damping mass for the torsional vibration damper and for the torsionally flexible coupling, the modular unit being arranged between a drive side and a driven side, the drive side and the driven side being axially spaced from each other and being coupled to each other by the modular unit, the common damping mass being comprised of a damping mass of the torsional vibration damper on the driven side which is resiliently connected to a spring means to a part on the drive side, a damping mass of the torsionally flexible coupling on the drive side which is resiliently connected by another, separate spring means to a part on the driven side, and a part common to the torsional vibration damper and the torsionally flexible coupling, the latter part holding the damping mass of the torsional vibration damper and the torsionally flexible coupling, the common damping mass, the part on the drive side and the part on the driven side forming concentrically arranged innermost, middle and outermost parts connected in pairs by radial leaf springs constituting said spring means, the leaf springs passing through openings in the middle part between the innermost and outermost parts.
