DRIVE SYSTEM FOR VARIABLE DISTRIBUTION OF TORQUE TO WHEELS OF A VEHICLE

Provided is a drive system (100) for a vehicle for variable distribution of torque, from a primary input (10) and secondary input (12), between a left wheel (22) and a right wheel (32) of a vehicle, the drive system (100) comprising a first (20) and second (30) torque output shaft, one for each of the left wheel (22) and the right wheel (32), an open differential (40), and independently controllable first (50) and a second (52) clutch packs, configured such that: torque from the primary input (10) is transferred to each of the torque output shafts (20, 30) via the clutch packs (50, 52); torque from the secondary input (12) is transferred to each of the torque output shafts (20, 30) via the open differential (40); torque from one output (44) of the open differential (40) is summed with torque from one clutch pack (50) output (50b) in the first (20) torque output shaft; and torque from another output (46) of the open differential (40) is summed with torque from the other clutch pack (52) output (52b) in the second (30) torque output shaft.
