Method of assembling a sub-assembly of a diaphragm spring friction clutch

摘要

The invention relates to diaphragm spring friction clutches in which the diaphragm spring is supported on a cover by tabs which extend through slots between the fingers of the diaphragm spring and are bent radially outwards on assembly over an adjacent arc of a fulcrum ring which is on the opposite side of the spring to the cover. To achieve firm clenching of the diaphragm spring and the fulcrum ring by the tabs, during the bending operation each tab is supported against radially inward movement where it extends through the spring slot while the fulcrum ring is supported against radially outward movement over those arcs which are gripped by the tabs.
