ABSTRACT:
A mechanical automatic torque limiting clutch containing an axially frangible and easily replaceable component is disclosed. The clutch is capable of limiting torque output by adjusting the friction between spring loaded input and output plates, and further is capable of preventing damage to other driveline components due to axial tension loads imparted to the driveline. The clutch allows a central axial bolt to break in tension should axial tension loads be applied which exceed the limits of the bolt, thereby protecting the remainder of the driveline components. When such a break occurs, the only damage done is to the bolt itself, which allows the input and output sides of the clutch to separate into two components which are quickly, easily and economically reassembled with a new bolt. Provision for weaker tensile loads is provided by use of bolts containing one or more grooves or indentations, which serve to reduce the cross sectional area and therefore the tensile strength of the bolt to the desired degree, or with a smaller diameter bolt and properly sized sleeves in order to prevent play between the bolt and axial bolt hole.
