Abstract
A method of fabricating a fluid coupling assembly (20, 120, 220, 320 and 420) of the type including a housing having spaced side walls (24, 124, 224 and 434) extending radially relative to an axis (A) and defining a fluid chamber surrounding a disc (30, 130) supported by a shift (26) extending through and rotatably supported by one of the side walls with cooling fins for cooling the fluid chamber. The invention is characterized by fabricating a cooling sub-assembly (44, 46, 48, 144, 244, 246, 248, or 444) of cooling fins connected to a ring (50, 54, 58, 150, 250, 350, 450 and 472) having an axis with the cooling fins extending radially and axially of the ring. Subsequently, the cooling sub-assembly is secured to the housing by placing the ring axially between the side walls so as to transmit heat from the housing to the cooling fins. The housing and/or the disc may be fabricated from sheet metal. The cooling sub-assemblies may be of various embodiments and a plurality of cooling sub-assemblies (44, 46, 48) may be attached to each housing.
