초록 ▼

A diaphragm spring is maintained in concentric relation with the clutch axis by integral support means formed on the clutch cover member. The diaphragm spring has a plurality of openings and the integral support means includes circumferentially spaced tang portions extending axially from the cover through certain of the openings and circumferentially spaced tab portions extending axially from the cover through other of the openings in the diaphragm spring. The tang and tab portions engage the openings in such a manner as to prevent both relative radial movement between the diaphragm spring and cover and relative rotational movement therebetween.

In a clutch the combination comprising: a. a rotatable flywheel; b. a cover secured to said flywheel for rotation therewith; c. an axially movable driven member positioned adjacent said rotatable flywheel and movable into driving engagement therewith; d. an axially movable pressure plate disposed between said cover and said driven member for engaging said driven member with said flywheel; e. resilient strap means drivingly connecting said pressure plate to said cover and permitting relative axial movement therebetween; f. a diaphragm spring disposed between said cover and pressure plate having an annular bearing portion engaging said cover and said pressure plate to move the latter into engagement with said driven member and a plurality of integral radially inwardly extending levers defined by radial slots in said spring operable to move said spring out of contact with said pressure plate; g. a series of spaced openings formed in said diaphragm spring and at the radial extremity of said slots and adjacent said bearing portion of said spring, each opening defining a pair of flat, radially extending side walls on said levers and a flat, outer horizontally extending connecting wall adjacent the radially inward edge of said bearing portion, said side walls being connected to said outer wall by radiused corners; h. axially extending radial supporting means integral with said cover, extending through certain of said spaced openings and having a flat, circumferentially extending surface engaging said flat, outer, horizontally extending connecting wall between said radiused corners for preventing relative radial movement between said cover and said diaphragm spring; and i. axially extending rotational support means integral with said cover, located radially inwardly of said radial support means, extending through certain other of said spaced openings and extending across said openings from one of said side walls to the other of said side walls and having flat radial side edges engaging said pair of flat side walls on said levers for preventing relative rotational movement between said cover and said diaphragm spring.
