Abstract

A clutch, comprising, in combination: a) a rotary handwheel; b) a cover or cover secured to said steering wheel to rotate therewith; c) an axially movable driven member, located adjacent to said rotary and movable flywheel to drive coupling therewith; d) an axially movable pressure plate, disposed between said cover and said driven member for coupling said driven member with said steering wheel; e) means of elastic bands connecting said pressure plate to said cover for driving and allowing relative axial movement between them; f) a diaphragm spring disposed between said covers and pressure plate, having an annular support part which is applied to said cover and pressure plate for moving the latter into engagement with said actuating member and a plurality of integral levers which extend radially inward, defined by radial slits 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 end of said slits or slots and adjacent said support part of said spring, each opening defining a pair of radially extending flat side walls, said levers, and a horizontal, flat, outer connection wall, adjacent to the radially internal edge of said support part, said side walls being connected to said outer wall by rounded corners; h) axially extending radial support means, integral with said cover, which extend through some of said spaced openings and having a circumferentially extending flat surface, which is applied to said outer flat connecting wall which is extends horizontally, between said rounded corners, to prevent 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, which extend through some of said other separate openings and which pass through said openings from one of said side walls to the other of said side walls and which have flat radial side edges which are applied to said pair of side walls in said levers to prevent the relative rotation movement between said cover and said spring of diaphragm (Machine-translation by Google Translate, not legally binding)
