    摘要: An exemplary differential apparatus for a vehicle includes: a compound planetary gear set and a planet carrier. In particular, the compound planetary gear set is formed as a combination of first and second planetary gear sets, the first planetary gear set is formed as a single pinion planetary gear set having a first sun gear and a plurality of first pinion gears, and the second planetary gear set is formed as a double pinion planetary gear having a second sun gear disposed coaxially and in parallel with the first sun gear, the plurality of first pinion gears shared with the first planetary gear set, and a plurality of second pinion gears. The planet carrier has an exterior circumference connected to an external gear and is connected to first and second pinion shafts that rotatably support the first and second pinion gears of the second planetary gear set.

    摘要: A power transmission apparatus for an electric vehicle including a motor as a power source may include: a compound planetary gear set formed as a combination of first and second planetary gear sets sharing a sun gear and a plurality first pinion gears; a first brake selectively connecting a first ring gear of the first planetary gear set to a transmission housing; and a second brake selectively connecting the shared sun gear of the first and second planetary gear sets to the transmission housing. In particular, a second ring gear of the second planetary gear set is fixedly connected to a rotor of the motor and thus continuously receives a torque of the motor, and the power transmission apparatus outputs a shifted torque through a planet carrier rotatably supporting the plurality of first pinion gears and a plurality of second pinion gears of the first planetary gear set.
