Abstract

1493002 Mounting clutch discs on hubs FICHTEL & SACHS AG 8 April 1975 [13 April 1974] 14346/75 Heading F2U A clutch disc assembly comprising first and second cover discs 3, 4 connected together as by rivets 6 is resiliently-mounted on a hub 1, 2 by means of helical springs 7 mounted in windows in the parts, a control plate 9 being provided between the hub disc 2 and the cover disc 4 carrying the linings 5 and having at least one bent-over lug 12 pressed against an edge of a corresponding window with a corresponding helical spring; the friction disc 13 between the control plate and the cover disc has a greater friction value than that of the friction disc 14 between the control plate and the hub disc so that upon traction (anticlockwise) the control plate is held by the helical spring and the cover discs slip with the greater amount of friction and so that upon thrust by the mass of the vehicle (clockwise) when the hub disc moves first, the control plate is released from spring pressure, and is taken along by the cover discs and slips with the smaller amount of friction on the hub disc. As shown, a further friction disc 15 of small friction value and an intermediate disc 16 is provided and the whole assembly is pressed together by a spring 8. The friction disc 13 may be made of an organic composition and the friction discs 14, 15 may be made of P.T.F.E. In another embodiment, Figs. 4 to 6 (not shown) the control plate (10) has two lugs (12) for engaging windows in the hub disc (2) and two lugs (17) for engaging in openings (18) in the cover disc (4), the latter lugs ensuring frictional drive of the control plate by the cover disc in the thrust direction when the difference of the friction values is not sufficient.
