DRIVE APPARATUS FOR HYBRID VEHICLE

摘要

A drive apparatus for a hybrid vehicle includes: an engine applying a drive force to drive wheels via a drive shaft; a motor applying a drive force to the drive wheels via a rotation shaft; a planetary gear mechanism having first, second, and third elements lining up sequentially with a gap interposed therebetween corresponding to a gear ratio; and an automatic transmission having input and output shafts rotatably connected to the drive wheels, and changing a gear ratio obtained by the division of the rotation speed of the input shaft by the rotation speed of the output shaft, wherein the input and drive shafts are connected to the second element, the output shaft and one end of the rotation shaft are connected to the first element, and the output shaft and the other end of the rotation shaft are connected to the third element.

1. A drive apparatus for a hybrid vehicle comprising:
an engine that applies a drive force to drive wheels via a drive shaft; a motor that applies a drive force to the drive wheels via a rotation shaft; a planetary gear mechanism that has a first element, a second element, and a third element which line up sequentially with a gap interposed therebetween corresponding to a gear ratio in a speed diagram; and an automatic transmission that has an input shaft, and an output shaft rotatably connected to the drive wheels, and changes a gear ratio that is obtained by the division of the rotation speed of the input shaft by the rotation speed of the output shaft, wherein the input shaft and the drive shaft are connected to the second element, the output shaft and one end of the rotation shaft are connected to the first element, and the output shaft and the other end of the rotation shaft are connected to the third element.
