Abstract:
1. A gear assembly for a motor vehicle, comprising: an input shaft including a first end configured to receive input torque from a first vehicle component and a second end configured to transmit torque; an output shaft including a first end configured to transmit output torque to a second vehicle component and a second end configured to receive torque; a planetary gear train including a ring gear, a sun gear, a plurality of planet gears, and a carrier; and a slide member rotationally coupled to the input shaft to receive input torque; wherein the slide member is configured to slide between a first position and a second position in a sliding direction relative to the second end of the input shaft; wherein at the first position, the slide member engages the ring gear of the planetary gear train so that the slide member and ring gear rotate together to transmit torque from the input shaft to the output shaft through the slide member and planetary gear train such that the output torque relative to the input torque is a first gear ratio; wherein at the second position, the slide member engages the output shaft without engaging the planetary gear train to transmit torque from the input shaft to the output shaft through the slide member such that the output torque relative to the input torque is a second gear ratio; wherein when the slide member is between the first and second positions, the slide member engages neither the planetary gear train nor the output shaft, and the input torque is not transmitted from the input shaft to the output shaft.
