US 12,359,694 B2 · Torsional vibration damper having an axis of rotation for a drive train

Abstract

A torsional vibration damper for a drive train includes an axis of rotation, a multi-flange damper for damping torsional vibrations, a torque limiter unit for limiting a maximum transmissible torque, an outer hub connecting the multi-flange damper to the torque limiter unit for torque transmission, and an inner hub for connection to a transmission input shaft. The multi-flange damper has a plurality of flanges. The torque limiter unit is arranged radially inside the multi-flange damper and includes an inner plate and an outer plate. The outer hub is arranged radially between the multi-flange damper and the torque limiter unit and the inner hub is arranged radially inside the torque limiter unit. The outer hub includes an external toothing engaged with each of the plurality of flanges and an internal toothing engaged with the outer plate.
