Torque-switched clutch

A torque-switch clutch between an input shaft and an output shaft, which transfers into a release position from a positive-locking connection when a limiting torque is reached, the clutch comprising two positive-locking elements, each of which is pivotably mounted on the output shaft for movement between a latch locking position and a latch overrun position, and interacts with a respective positive-locking recess provided on the input shaft, each positive locking element being mounted on a respective cup element which is displaceable in the output shaft in a direction substantially perpendicular to the shaft axis, and the cup elements being urged radially outwards of the output shaft by resilient means, so that each positive-locking element is movable against a force exerted by said resilient means out of a coupling position into a release position in a non-destructive manner, wherein the positive-locking element are configured to move by both an anticlockwise and clockwise rotation of the shaft when the limiting torque is exceeded from a latch locking position to a latch overrun position and in the latch overrun position a torque transmission is produced by a reversal of the direction of rotation until a limiting torque has been reached.

A torque-switched clutch between an input shaft and an output shaft, which transfers into a release position from a positive-locking connection when a limiting torque is reached, the clutch comprising at least one positive-locking element, which is connected to output shaft and interacts with a positive-locking receiver of the input shaft, the positive-locking element being movable out of a coupling position into a release position in a non-destructive manner, wherein the positive-locking element is arranged so as to be rotatable relative to the input shaft for movement between a latch locking position and a latch overrun position, wherein the positive-locking element is connected to a first cup element, which can be displaced in the output shaft substantially perpendicular to the shaft axis, an element for applying a force to the positive-locking element being accommodated in the interior of the cup, wherein a spring element is arranged substantially concentric with a first compression spring, the first compression spring effecting the application of said force to the positive-locking element.
