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.
