  • Publication number: 20150211607
    Abstract: A transmission for hybrid vehicle includes a change-speed gear assembly, an engine-side connector, and a motor-side connector. The change-speed gear assembly includes drive gears and driven gears making change-speed stages. A specific drive gear of the drive gears, and a specific driven gear of the driven gears, making a specific change-speed stage (e.g., the fifth-speed change-speed stage) of the change-speed stages, are made switchable between the idling state and the rotary connection state. The engine-side connector switches the other drive gears and driven gears, making the other change-speed stages, between the idling state and the rotary connection state, respectively. The motor-side connector includes a motor-side drive gear meshing with a motor-side driven gear doubled as the specific drive gear. The motor-side connector switches the specific drive gear, and the specific driven gear between the idling state and the rotary connection state, respectively.
