Abstract
An overload clutch which is prevented from unintentionally switching into the freewheeling position when rotational vibrations occur includes torque-transmitting members held in apertures of a first clutch member and adapted to be engaged in first recesses of a second clutch member for bringing the clutch into torque-transmitting engagement. A switching ring includes second recesses adapted to align with the apertures in the first clutch member when an overload condition occurs. A circumferentially acting spring tends to hold the switching ring in the torque-transmitting position and a securing pin is mounted in the first clutch member for engagement in a detent in the switching ring to hold the switching ring in torque-transmitting position. The securing pin is held in engagement with the detent by a spring but is arranged so as to extend into the detent a distance which will permit disengagement of the securing pin when a predetermined nominal torque of the clutch is exceeded.
