Abstract

To provide desired shaft torque to a drive wheel without increasing the number of parts or increasing the size of a motor, to improve cooling capability of a generator housed inside a transmission case, and to improve energy transmission efficiency and electrical generation efficiency in an engine unit of a hybrid vehicle. A power unit structure for a hybrid vehicle is provided with an engine (20), a continuously variable transmission (23), a driven shaft (60), a drive motor (21b) and a reduction gear mechanism (69). The drive motor (21b) is attached to the reduction gear mechanism (69).

Description

[0001] Cross References to Related Applications [0002] This non-provisional application is related to Japanese Patent Applications 2003-338823, 2003-338824, 2003-338825 (each filed on September 29, 2003). The entirety of each of the above documents is incorporated into this application by reference. technical field [0003] The present invention relates to a power unit structure of a hybrid vehicle having an engine and an electric motor as power sources. Background technique [0004] In the background art, a well-known hybrid vehicle has a power transmission device for transmitting power of an engine to drive wheels mounted in a gearbox. The power transmission unit combines and transmits the power of the engine and the motor to a drive shaft (for example, Japanese Patent Publication Hei 8-175473). The hybrid vehicle disclosed in the above-mentioned document has a generator connected directly or through a reduction gear to a drive shaft in a power transmission. [0005] ...
