Abstract:
1. A torque transmitting device in a drive train of a motor vehicle for transmission of torque between a drive unit having an output shaft and a transmission having at least one transmission input shaft that is coupled to the output shaft of the drive unit by a clutch, said torque transmitting device comprising: a torsional vibration damper positioned between the drive unit and the transmission and including a primary flywheel mass, a secondary flywheel mass, and at least one energy storage device carried by the primary flywheel mass for engagement with an output part carried by the secondary flywheel mass, wherein the primary flywheel mass and the secondary flywheel mass of the torsional vibration damper and the clutch are each radially supported on respective bearings each carried by the at least one transmission input shaft and are each rotatable relative to the at least one transmission input shaft, wherein the primary flywheel mass is operatively connected through a radially-extending carrier plate that includes a radially-extending outer attachment flange for attachment to a drive plate that is operatively connected with the drive unit output shaft, and that includes a radially-extending inner attachment flange that abuts a radial step formed on an annular connecting element, wherein the outer and inner radially-extending flanges of the carrier plate are spaced from each other in an axial direction of the torque transmitting device, wherein the primary flywheel mass and the carrier plate are attached to the annular connecting element, wherein the annular connecting element includes two opposed end faces including a first radially-extending end face that faces the transmission and to which the primary flywheel mass is attached, and a second radially-extending end face that faces the drive unit and to which the carrier plate is attached, wherein a radially outwardly facing step is provided on the first end face of the annular connecting element to abut a radially inner circumferential rim of the primary flywheel mass, wherein the radial step is provided on the second end face of the annular connecting element to abut a radially inner circumferential rim of the carrier plate, and wherein the radial step and the radially outwardly facing step are disposed radially inward of a radially outermost surface of the annular connecting element.
