1. A torque limiter for a drive train, comprising:
a rotational axis;
a first cover disc and a second cover disc;
a central disc arranged axially between the first cover disc and the second cover disc;
a first friction lining arranged axially between the first cover disc and the central disc for frictionally locking torque transmission between the first cover disc and the central disc;
a second friction lining arranged axially between the second cover disc and the central disc for frictionally locking torque transmission between the second cover disc and the central disc;
a radially outer connector permanently connected to the first cover disc and the second cover disc in a torque-transmitting manner; and
a radially inner connector permanently connected to the central disc in a torque-transmitting manner, wherein the central ring is a single-piece ring comprising;
an outer ring portion comprising multiple separate radially outer segments spaced apart from one another in radial overlap with the first friction lining and the second friction lining in a rotation direction, the radially outer segments forming a spring element arranged between the first friction lining or and the second friction lining; and
multiple separate radially inner segments spaced apart from one another in the rotation direction and connected directly to a torsional vibration damper.
