Hybrid drive device

摘要

A hybrid drive device includes: a gear mechanism that divides and transmits rotary power of an internal-combustion engine to first motor generator and second motor generator; a first shaft to which rotary power of the first motor generator is transmitted; a rotary element; a second shaft to which rotary power of the rotary element is transmitted after deceleration; a third shaft to which rotary power of the second shaft is transmitted after deceleration; a first power-transmission switching mechanism that can switch rotary power of the second motor generator among a state of being transmitted to the rotary element, a state of being transmitted to the third shaft, and a state of not being transmitted; and a second power-transmission switching mechanism that can switch rotary power of the first shaft between a state of transmission to the second shaft and a state of not transmitted.

1. A hybrid drive device, comprising:
a gear mechanism formed of a planetary gear mechanism which is disposed between a first motor generator and a second motor generator, and wherein the gear mechanism divides and transmits rotary power from an internal combustion engine to the first motor generator and the second motor generator; a first shaft positioned relative to the first motor generator so that rotary power from the first motor generator is transmitted to the first shaft; a rotating element; a second shaft positioned relative to the rotating element so that rotary power from the rotating element is transmitted to the second shaft; a third shaft which drives wheels and is positioned relative to the second shaft so that rotary power from the second shaft is transmitted to the third shaft; a first power transmission switching mechanism that can switch among a state wherein the rotary power from the second motor generator is transmitted to the rotating element, a state wherein transmission to the third shaft is allowed, and a state wherein transmission to the rotating element and to the third shaft is not allowed; and a second power transmission switching mechanism that can switch between a state wherein transmission of the rotary power from the first shaft to the second shaft is allowed, and a state wherein transmission to the second shaft is not allowed, wherein the first shaft and the second shaft are coaxially disposed; the third shaft and the rotating element are coaxially disposed; the first shaft is disposed on a different axis from the rotating element; and wherein the planetary gear mechanism comprises:
a sun gear that connects to the first motor generator;a pinion gear(s) that engages with the sun gear;a ring gear that engages with the pinion gear(s) and connects to the second motor generator; anda carrier that rotatably supports the pinion gear(s) and, outputs rotary power from the internal combustion engine to the pinion(s) gears.
