<p>A clutch arrangement (10) for co-axial shaft members including a drive or input shaft member (12 or 14) and a driven or output shaft member (14 or 12); the arrangement having a disc (20) concentrically mountable on one of the shaft members for rotation with the one shaft member; a plate member (28) mountable on the other shaft member for rotation therewith and so as to extend at least diametrically of the other shaft member in substantially parallel relation with the disc (20), the plate member (28) having at least two openings (46) therethrough each axially in line with the disc (20); a respective axially extending, force applying arm (48) located in each opening; a frame member (50) inter-connecting each of the force applying arms (48); and respective friction pad means (52) on each side of the disc (20), each pad means (52) being operatively mounted such that on application of an axial force to the frame member (50), the axially extended arms (48) are movable to cause each of the pad means (52) to move relative to the disc (20) from one to the other of two relative positions, in a first of which positions the pad means (52) grip the disc (20), and in the second of which positions the pad means (52) release the disc (20); the disc (20) being rotatable with each of the plate member (28), the arms (48) and the frame member (50) with the pad means (52) in their first position, and being rotatable relative to each of the plate member (28), the arms (48) and the frame member (50) with the pad means (52) in their second position.</p> |
