Abstract
A torque vectoring differential apparatus disposed in a vehicle powertrain includes an engine, transmission, and a torque vectoring differential. The torque vectoring differential includes a bevel gear differential assembly having a carrier input and side gear outputs. The side gear outputs are controlled to distribute torque from the torque and speed from the input member to the individual side gears through two speed control mechanisms each of which is controlled by respective individually selectively engageable torque-transmitting mechanisms. The differential assembly, and the speed control mechanisms are disposed in separate housings.
