  • Patent number: 4423804
    Abstract: A friction clutch assembly incorporates a pressed steel cover member 11 having an annular pressure plate 13 arranged within a recess 12 in the cover 11. Drive straps 21 connect lugs 17 of the pressure plate to the cover and allow relative axial movement between cover and pressure plate. A diaphragm spring 22 provides a clutch clamping load tending to urge the pressure plate out of the recess in the cover. Stops 23, integral with the cover and set back from the mounting flange 14 of the cover, are arranged to engage directly the lugs 17 of the pressure plate to prevent excess movement of the pressure plate which could deflect the drive straps 21 excessively.

  • Patent number: 4413716
    Abstract: A friction clutch incorporates a flywheel 11, a driven plate 23, and pressure plate 16 with friction interfaces 24 and 25 between pairs of these members lubricated and/or cooled by fluid flung out centrifugally. A generally bell shaped distribution member constituted by a conical member 41 and part of the driven plate hub member 33 directs fluid past the interface 25 to a passage leading outward to the interface 24. Apertures 47 around the circumference of the distribution member allow some fluid to escape through the distribution member through a radial passage to the interface 25. Substantially equal distribution of oil between the two interfaces is achieved.
