Abstract
A gear assembly for a motor vehicle includes first clutch configured to selectively couple an input shaft to an output shaft and a second clutch configured to selectively couple the input shaft to a planetary gear train. When the first clutch is activated and the second clutch is not activated, the input torque is transmitted from the input shaft to the output shaft such that the output torque relative to the input torque is a first gear ratio. When the second clutch is activated and the first clutch is not activated, the input torque is transmitted from the input shaft to the output shaft through the planetary gear train such that the output torque relative to the input torque is a second gear ratio. When neither the first clutch nor the second clutch are activated, the input torque is not transmitted from the input shaft to the output shaft.
