Abstract: The present invention relates to a freewheel-damper assembly (2) for a motor vehicle, having a torsional vibration damper (18) with a primary element (20) which is connectible or connected, on a drive side (36) of the torsional vibration damper (18), to a drive shaft (38), and with a secondary element (22) which is torsionally elastically coupled to the primary element (20) and which is connectible or connected, on an output side (46) of the torsional vibration damper (18) facing away from the drive side (36), to a transmission input shaft (48), and with a starter freewheel (58), via which the primary element (20) can be indirectly or directly driven by a starter motor (60). The starter freewheel (58) is arranged on the output side (46) of the torsional vibration damper (18). The present invention moreover relates to a drivetrain for a motor vehicle having such a freewheel-damper assembly (2).

Abstract: The present invention relates to a freewheel damper arrangement (2) for a motor vehicle having a torsional vibration damper (18) having a damper shell (22), spring elements (30) arranged in the damper shell (22) and a damper flange (34) coupled torsionally elastically to the damper shell (22) via the spring elements (30), and a starter freewheel (20) having a first race (58) which can be driven by a starter motor (70) and a second race (60) which is assigned to the damper shell (22), between which clamping elements (62) are arranged. The second race (60) is non-rotatably fastened to the damper shell (22).
