Abstract
A transfer case of a motor vehicle drivetrain includes a planetary gear set including a ring gear to receive input torque, and a pinion assembly having pinion gears in mesh with the ring gear and a carrier to carry the pinion gears and transmit output torque. A sun gear is in mesh with the pinion gears, is selectively connectable to the carrier and rotatable therewith in a two-wheel drive mode and in a four-wheel-drive high range mode, and is selectively fixable against rotational motion in a four-wheel drive low range mode.
Claims15
A motor vehicle transfer case, comprising:
- an input to receive torque;
- an output to transmit torque;
- and
- a planetary gear set between the input and the output, and including:
- a ring gear connected to the input,
- a pinion assembly connected to the output and including pinion gears in mesh with the ring gear and a carrier to carry the pinion gears, and
- a sun gear in mesh with the pinion gears, selectively connectable with the carrier to rotate with the carrier in a two-wheel drive mode and in a four-wheel-drive high range mode, and selectively groundable against rotation in a four-wheel-drive low range mode.
