TRANSMISSION APPARATUS OF HYBRID VEHICLE

摘要

A transmission apparatus of a hybrid vehicle is provided. The apparatus includes a planetary gear set including a first rotation element connected to an engine, a second rotation element connected to a first motor/generator, and a third rotation element connected to a second motor/generator. An output gear is connected to any one of the second and third rotation elements and a two-way clutch is mounted at the first rotation element. The clutch limits D stage rotation in a first side direction or limits R stage rotation in a second side direction selectively based on a position of a lever. Accordingly, the clutch performs a failsafe function by preventing a shifting stage from being applied to the R stage when the engine is driven.

1. A transmission apparatus of a vehicle, comprising:
a planetary gear set including a first rotation element connected to an engine, a second rotation element connected to a first motor/generator, and a third rotation element connected to a second motor/generator; an output gear connected to any one of the second and third rotation elements; and a two-way clutch mounted at the first rotation element and configured to limit a drive (D) stage rotation in a first side direction or limit a reverse (R) stage rotation in a second side direction selectively based on a position of a lever.
