Vectoring axle drive

A vectoring drive for a vehicle comprising:

• a case;
• a motor disposed in the case and including a rotor, a tubular output shaft defining a central opening, and a stator disposed around an outer diameter of the rotor;
• a linking shaft extends through the central opening;
• a torque multiplying gear set connected to the tubular output shaft provides torque to the linking shaft;
• a first planetary gear set on a right end of the linking shaft has a first sun gear that receives torque through the linking shaft from the torque multiplying gear set;
• a second planetary gear set on a left end of the linking shaft has a second sun gear that receives torque through the linking shaft from the torque multiplying gear set;
• a first grounding clutch normally locks a first ring gear of the first planetary gear set to the case;
• a second grounding clutch normally locks a second ring gear of the second planetary gear set to the case;
• a right axle shaft operatively connected to a first carrier of a first plurality of planet gears of the first planetary gear set;
• and
• a left axle shaft operatively connected to a first carrier of a second plurality of planet gears of the second planetary gear set, wherein torque is provided equally to both right and left axle shafts with both ring gears locked, wherein torque provided to the right axle shaft is reduced by the first grounding clutch partially releasing the first ring gear and selectively allowing the first ring gear to slip, and wherein torque provided to the left axle shaft is reduced by the second grounding clutch partially releasing the second ring gear and selectively allowing the second ring gear to slip.

A torque vectoring system comprising:

• a housing with a first end and a second end disposed opposite the first end;
• an interconnecting member rotationally supported by the housing;
• a first planetary gear set and a second planetary gear set disposed adjacent the first end and the second end of the housing, respectively;
• a first sun gear and a second sun gear of the first and the second planetary gear sets, respectively, are each fixedly joined for common rotation to the interconnecting member;
• a first output member and a second output member, and wherein the first output member is fixedly joined for common rotation to a first carrier member of the first planetary gear set, and the second output member is fixedly joined for common rotation to a second carrier member of the second planetary gear set;
• a first clutch selectively connects a first ring gear of the first planetary gear set to the housing;
• and
• a second clutch selectively connects a second ring gear of the second planetary gear set to the housing, wherein partial release of the first clutch reduces a first torque ratio between the interconnecting member and the first output member and partial release of the second clutch reduces a second torque ratio between the interconnecting member and the second output member.
