ABSTRACT:
Torque transmitting fluid couplings of two types are described, one a thermatically controlled coupling and the other a torque limiting coupling. Both are characterized by the use of parts which can be manufactured at low cost and easily and quickly assembled, and contribute to greater efficiency in operation than fluid couplings of these types which have heretofore been marketed. Both utilize a housing or casing which is die-cast complete and finish bored, a drive shaft and coupling flange made of two separate pieces, which are welded together, ball bearing mounts, a cover or cover member made as a metal stamping, and a drive disc which is die-cast, in a single piece, to provide a friction ring and friction segments molded integrally therewith. In the thermatically-controlled type, the cover is part of a cover assembly, which comprises a bracket for supporting a bimetal strip, a steel guide bushing riveted to the cover and in which a piston or pin is adapted to be slidably mounted, and a rubber piston seal for preventing leakage of fluid through the cover. The thermatically-controlled type also includes a plate and spring assembly, comprising a divider plate made as a steel stamping and a spring made of spring steel and supporting a weir made of a graphite-filled material.
