TRANSMISSION FOR HYBRID VEHICLE

摘要

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.

1. A transmission for hybrid vehicle, the transmission comprising:
an input shaft to be rotatably connected to a rotary shaft of an engine; an output shaft to be rotatably connected to drive wheels; a change-speed gear assembly including drive gears disposed on the input shaft, driven gears disposed on the output shaft to mesh with the drive gears, the drive gears and driven gears making change-speed stages, respectively, wherein: a specific drive gear of the drive gears and a specific driven gear of the driven gears, which make a specific change-speed stage of the change-speed stages, are made switchable between an idling state and a rotary connection state: and the other drive gears and driven gears, which make change-speed stages other than the specific change-speed stage, are made switchable between an idling state and a rotary connection state, respectively; an engine-side connector operating to switch one of the drive gears and the driven gears, which make change-speed stages other than the specific change-speed stage, between the idling state and the rotary connection state, respectively; and a motor-side connector including a motor-side drive gear to be rotatably driven by a motor while meshing with a motor-side driven gear doubled as one of the specific drive gear and the specific driven gear, a drive-side sub-connector operating to switch the specific drive gear between the idling state and the rotary connection state, and a driven-side sub-connector operating to switch the specific driven gear between the idling state and the rotary connection state.
