Abstract:
A torsional vibration damping device in the drive train of a motor vehicle, comprising:a first cover plate rotatably arranged for rotating about an axis of rotation;a second cover plate fixed with respect to rotation to said first cover plate and arranged at an axial distance from said first cover plate;a coaxial internally located part arranged between said first and second cover plates and rotatable about said axis of rotation relative to said first and second cover plates;a spring element having a spring force circumferentially arranged between said internally located part and said first and second cover plates such that said internally located part is rotatable relative to said first and second cover plates against said spring force; anda plurality of discrete distance pieces axially arranged between said first and second cover plates for holding said first cover plate at said axial distance from said second cover plate, each of said plural distance pieces having a joint region proximate each axial end of said each of said plural distance pieces for connecting said distance piece to said first and second cover plates and a connecting region extending between said first and second cover plates, wherein said each of said plural distance pieces comprises a U-shaped configuration so that a first radial distance between said joint regions and said axis of rotation is different from a second radial distance between said connecting region and said axis of rotation, and wherein said internally located part comprises circumferentially extending apertures through which said plural distance pieces respectfully extend, said joint regions of said plural distance pieces being inserted into corresponding openings in said first and second cover plates.
