Abstract: A self-adjusting mechanism for a friction clutch is disclosed. The mechanism includes first and second hub members with mating ratchet teeth, and an adjustment arm having a non-slip connection with the first hub member for driving the first hub member in opposite rotational directions, and a worm gear which, when rotated, moves an adjustment ring of the clutch to adjust the friction surfaces to compensate for wear. The mechanism also includes a lost-motion connection located between the worm gear and the release mechanism of the clutch. The adjustment arm on the first hub member has a connection with the release mechanism of the clutch. The release mechanism is movable through an adjustment cycle during which the worm gear is rotated to move the adjustment ring of the clutch to adjust friction surfaces to compensate for wear.

Abstract: A clutch brake for use in association with a braking mechanism for braking rotation of a shaft connecting an engine to a transmission. The clutch brake includes first and second clutch brake sections having first and second lock plates. The first and second clutch brake sections are selectively configurable in a disconnected configuration and a connected configuration. The clutch brake further comprises a fastening mechanism on the first and second lock plates for fastening the first and second clutch brake sections in the connected configuration. The fastening mechanism includes a first fastening component on the first lock plate and a second fastening component on the second lock plate. The first fastening component further includes a fastener body movably mounted in an opening in the first lock plate, and a fastening arm extending from the fastener body. The fastener body is movable from a fastening position, to a release position.

Abstract: A friction clutch assembly connects driving and driven shafts and has a pressure plate axially moveable between an engaged position transmitting torque from the driving shaft to the driven shaft and a disengaged position. The assembly includes levers and a plurality of centrifugal-assist weights on the levers adjacent outer ends of the levers. The centrifugal-assist weights are arranged to apply an increased force urging the pressure plate to its engaged position upon rotation of the cover and the levers. The centrifugal-assist weights are suitably configured to provided the desired amount of increased force.
