POWER TRANSMISSION APPARATUS FOR VEHICLE

摘要

A power transmission apparatus for a vehicle may include a first input shaft on which at least one input gear is disposed, a second input shaft on which at least one other input gear is disposed, a first shifting output device including at least one shifting gear and a first output shaft, the at least one shifting gear being selectively synchronized with the first output shaft such that torque input from the first and second input shafts is output to a final drive gear, a second shifting output device including at least one other shifting gear and a second output shaft, the at least one other shifting gear being selectively synchronized with the second output shaft such that the torque input from the first and second input shafts is output to the final drive gear, and an idle device including an idle shaft and at least three idle gears.

1. A power transmission apparatus for a vehicle, comprising:
a first input shaft comprising a solid shaft on which at least one input gear is disposed, the first input shaft being selectively connectable with an output side of a power source by a first clutch; a second input shaft comprising a hollow shaft on which at least one other input gear is disposed, the second input shaft surrounding the first input shaft at a forward portion of the first input shaft without interference, the second input shaft being selectively connectable with the output side of the power source by a second clutch; a first shifting output device including at least one shifting gear and a first output shaft, the first output shaft being disposed parallel to the first and second input shafts, the at least one shifting gear being rotatably disposed on the first output shaft and continuously engaged with the at least one input gear or the at least one other input gear, and the at least one shifting gear being selectively synchronized with the first output shaft such that torque input from the first and second input shafts is shifted and output to a final drive gear; a second shifting output device including at least one other shifting gear and a second output shaft, the second output shaft being disposed parallel to the first and second input shafts, the at least one other shifting gear being rotatably disposed on the second output shaft and continuously engaged with the at least one input gear or the at least one other input gear, and the at least one other shifting gear being selectively synchronized with the second output shaft such that the torque input from the first and second input shafts is shifted and output to the final drive gear; and an idle device including an idle shaft and at least three idle gears disposed on the idle shaft, the idle shaft being disposed parallel to the first and second input shafts, a first idle gear of the three idle gears being fixed to the idle shaft and engaged with one of the at least one shifting gear and the at least one other shifting gear of the first and second output shafts, a second idle gear of the three idle gears being engaged with one of the at least one input gear and the at least one other input gear and selectively synchronized with the idle shaft, and a third idle gear of the three idle gears engaged with a shifting gear fixed to one of first output shaft and second output shaft the first output shaft and the second output shaft and selectively synchronized with the idle shaft.
