Abstract:
A power transmission apparatus for an automobile comprising: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 is converted into electric power by a generator, and said electric power is supplied to said electric motor; anda mechanism for disconnecting said generator from a rotational force transmission system constructed by said internal combustion engine and said drive wheel, wherein the rotational force transmission system has a mechanism for selectively switching a first transmission system having a first transmission ratio, a second transmission system having a second transmission ratio, and a neutral state for disconnecting the rotational force transmission system;in the case where rotation is transmitted by said first transmission system, the rotational force transmission system is disconnected from said generator; andin the case where rotation is transmitted by said second transmission system, the rotational force transmission system is connected to said generator.
