  • Power transmission for an automobile
    Patent number: 4376370
    Abstract: A power transmission for an automobile, which is provided with an oil circulation type fluid coupling and a clutch mechanism so that power may be transmitted from an output shaft of an engine to an input shaft of a gear transmission. The output and input shafts support an intermediate shaft to which a pump at the fluid coupling is rotatably supported, so that a partition for supporting the intermediate shaft is eliminated. At the fluid coupling are provided an oil-charge passageway for charging to the fluid coupling a part of lubricating oil for the engine and an oil-return passageway for collecting into an engine oil pan the oil flowing out of the fluid coupling.
