ABSTRACT:
A clutch for a tire lift/carrier winch includes a drive plate and a driven plate having a plurality of elongate springs thereon. The driven plate includes circumferentially spaced driven end portions which are positioned in driving engagement with circumferentially spaced drive portions of the drive plate to permit rotation of the driven plate upon rotation of the drive plate when the load on the cable winding spool is within a prescribed limit. However, when the load on the cable winding spool exceeds the prescribed limit, the elongate springs on the driven plate function as cantilevered spring segments deflectable about respective fulcrums in such a manner as to prevent rotation of the driven plate upon rotation of the drive plate.
