  • Patent number: 10384529
    Abstract: A transmission for a vehicle may include a first input shaft selectively connected to an engine through a first clutch, a second hollow input shaft disposed in a front side portion of the first input shaft and selectively connected to the engine through a second clutch, a continuously variable transmission mechanism (CV) that continuously shifts and outputs rotation power transferred from the first input shaft, a shift output mechanism that receives rotation power transferred from driving gears on the second input shaft and the CV through driven gears connected to an external gear and selectively shifts and outputs the rotation power, a reverse idle mechanism that transfers the rotation power of the first input shaft to the shift output mechanism in a reverse direction, and a final reduction mechanism that reduces the rotation power output from the shift output mechanism.
