CPC F16D 7/025 (2013.01) [F16F 15/1297 (2013.01)] | 7 Claims |
1. A torque limiter for a drivetrain, comprising:
an axis of rotation extending along an axial direction;
a friction lining under a pre-stress acting in the axial direction, the friction lining comprising a cutout;
a drive side;
an output side connected to the drive side by the friction lining in a torque-transmitting manner until a limiting torque is reached;
a first friction surface on a one of the drive side or the output side;
a first contact surface between the friction lining and the first friction surface, the first contact surface comprising a first mean friction radius;
a second friction surface on the other of the drive side or the output side; and,
a second contact surface between the friction lining and the second friction surface, the second contact surface comprising a second mean friction radius, different than the first mean friction radius, wherein:
the cutout reduces the second contact surface and increases the second mean friction radius; and
when the limiting torque is exceeded:
the friction lining slides on the first friction surface; and
the friction lining is frictionally fixed to the second friction surface.
