Abstract: An apparatus is provided for use in a method of making a torque converter clutch. The torque converter clutch is comprised of an annular clutch plate to which is secured or bonded an annular friction surface. The annular friction surface is formed on the machine by die-stamping, from a flat sheet of friction material, successive arcuate segments.

Thus, the disk-shaped works are finally rotated in an integral relationship by the pin.

Abstract: A clutch structure has a housing in which is slidably disposed a fluid-operated piston, a plurality of inner and outer splined friction plates and a return spring assembly. The friction plates have formed thereon a spline portion such that alternating discs have the splines extending radially outward, engaging the housing, or extending radially inward, away from the housing. The clutch structure is assembled by positioning the clutch housing in a fixture composed of a ring which is sized to accommodate the outer spline of the one set of friction plates. The plates are arranged in two vertical stacks with the inner splined plates in one stack and the outer splined plates in the other. The plates are alternately installed in the housing by descending from the stacks solely by the force of gravity until a desired number of plates have been installed. The piston and a pressure plate can be installed in the housing prior to mounting the housing to the fixture, if desired.

The cover is centered on and is fastened to a flywheel of the output element before the tool is extracted from the output element, thereupon the clutch plate and ultimately from the housing. The tool is provided with a movable holding portion which maintains the tips of prongs forming part of the diaphragm spring in abutment with a locating portion of the tool to thus maintian the tips in a selected axial position. The holding portion can be disengaged from and can be moved through the splined hub of the clutch plate in response to angular and/or other movement relative to at least one of the centering portions.

Abstract: The present invention provides methods and apparatus for installing a cylindrical body, having a plurality of external axial splines, within a stack of annular plates, said plates having radially inner teeth for meshing with said splines. The method includes the placement of a cylindrical alignment tool, having a plurality of external splines, in a position subsequently to be occupied by said cylindrical body. The annular plates are placed about said alignment tool, with the teeth of said annular plates meshing with said alignment tool. Then, an axially compressive force is applied to said stack of plates to maintain axial alignment of the teeth of adjacent plates. This axial compressive force is supplied by a high pressure fluid which is communicated to a piston engaging said stack of plates. Then, the alignment tool is removed while said axial compressive force is retained on said stack of plates.
