Patent ID: 7491147

Claim:
A torque vectoring differential apparatus comprising: a differential mechanism having a carrier member, an input member and first and second output members disposed within a housing; a first speed control mechanism disposed within a second housing comprising a first drive gear rotatably connected to the carrier member, a first transfer gear intermeshed with the first drive gear, a first driven gear rotatably connected to the first output member, a second transfer gear intermeshed with the first driven gear, and a first selectively engageable torque-transmitting mechanism to selectively connect the first and second transfer gears to provide a speed differential between the input of the differential mechanism and said first output member; and a second speed control mechanism disposed within a third housing comprised of a second drive gear rotatably connected to the carrier member, a third transfer gear intermeshed with the second drive gear, a second driven gear rotatably connected to the second output member, a fourth transfer gear intermeshed with the second driven gear, and a second selectively engageable torque-transmitting mechanism to selectively connect the third and fourth transfer gears to provide a controlled speed differential between the differential input second output member.
