Problems solved by technology

However, the parallel shaft type transmission has large dimensions both in the axial direction and in the radial direction, so it is not suitable for mounting on a vehicle
The power output devices in the above-mentioned documents also require relatively large-sized rotors, resulting in bulky electrical drive systems that are not suitable for installation on vehicles
In addition, the possibility of actual use of the power output equipment in the above-mentioned later documents is also low.

Abstract

The invention relates to a power output device and a hybrid vehicle with the same configured with a power distribution integrating mechanism (40) and a gear box (60). The power distribution integrating mechanism (40) is a double-stage pinion planetary gear mechanism, comprising a planet carrier (45) connected to a motor (MG2), a sun gear (41) connected to a motor (MG1) and a ring gear (42) connected to a motor (22), having a speed ratio about 0.5. The gear box (60) comprises a triple element first gearing planetary gear mechanism (PG1), a triple element second gearing planetary gear mechanism (PG2), a break coupling (BC1) designed to fix a ring gear (62) of the first gearing planetary gear mechanism (PG1) in a non-rotating manner and releasing the same in a rotating manner, and a brake coupling (BC2) designed to permit or forbid power transmission performed by the second gearing planetary gear mechanism (PG2).

Description

technical field [0001] The present invention relates to a power output device configured to output power to a drive shaft, and to a hybrid vehicle equipped with the above power output device. Background technique [0002] One existing structure of a power output apparatus includes an internal combustion engine, two electric motors, a Ravigneaux-type planetary gear mechanism, and two output members arranged to selectively connect an output member with the planetary gear mechanism to the electric motors, respectively. A parallel shaft type transmission in which one of the elements is linked (for example, see Japanese Patent Laid-Open Publication No. 2005-155891). Another existing structure of a power output apparatus includes a planetary gear mechanism having an input element connected to an internal combustion engine and two output elements respectively connected to an electric motor; The output member and the two countershafts connected to the output shaft (for example, see...
