Abstract:
A power transmission apparatus for an automobile having a mechanism in which a rotational force of an internal combustion engine and a rotational force of an electric motor are synthesized or selectively switched to drive a drive wheel, the rotational force of said internal combustion engine or said drive wheel being convertible by a generator into electric power for being supplied to said electric motor, comprising:a mechanism configured to disconnect said generator from a rotational force transmission system comprised of said internal combustion engine and said drive wheel; wherein the rotational force transmission system has a mechanism for switching a first transmission system having a first speed change ratio to or from a second transmission system having a second speed change ratio such that, with rotation transmitted by said first transmission system, the rotational force transmission system is disconnected from said generator and, with rotation transmitted by said second transmission system, the rotational force transmission system is connected to said generator.
