摘要： A torque limiter for a drive train includes a rotational axis, a first cover disc and a second cover disc, a central disc arranged axially between the cover discs, a first friction lining and a second friction lining, a radially outer connector and a radially inner connector, and a spring element. The first friction lining is for frictionally locking torque transmission between the first cover disc and the central disc, and the second friction lining is for frictionally locking torque transmission between the second cover disc and the central disc. The radially outer connector is permanently connected to the cover discs in a torque-transmitting manner, and the radially inner connector is permanently connected to the central disc in a torque-transmitting manner. The spring element is arranged between the central disc and the first friction lining or the second friction lining.

摘要： 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.
