A system for a vehicle is disclosed. The system comprises a gear box. The gear box comprises a first shaft coupled to a first motor and a second shaft coupled to the second motor and a third shift. Each shaft extends through a respective pinion. The gearbox has a first shifter for the first motor and a second shifter for the second motor. The shifters are configured to selectively engage a respective pinion to an appropriate shaft as needed. The gear box further comprises a fourth shaft extending through a first gear and a second gear and an other pinion. The first gear meshes with a first pinion. The second gear meshes with a second pinion. The other pinion meshes with a third pinion and a fourth gear. A differential is mechanically coupled to the fourth gear and a left axle shaft and a right axle shaft.

Redundant, fault tolerant traction drive axle for vehicle

Systems and methods for reducing a likelihood that an engine exceeds its torque or power limit at a specific speed are provided. Also provided are systems and methods for reducing a likelihood that DC-DC converters and AC inverters overload a generator at a specific speed.

Low engine speed electric accessory load regulation on moving vehicles

A transmission drive system (TDS) has two AC induction traction motors, each operatively coupled to two semi-independent coaxial traction shafts, and two AC induction steer motors coaxially mounted on a common steer axis parallel to the coaxial traction shafts. A steering gear assembly, preferably between the traction and steering motors, has a common steer input shaft operatively connected to the two AC induction steering motors. Two planetary gear sets have the two traction shafts being operatively connected with one of a two planet gear carriers, or two ring gears, respectively. The other of the planet gear carriers or the ring gears are operatively connected with each other. Two offset gears mounted to the steer input shaft and meshing with two sun gears, respectively, including a reversing idler gear interposed between one of the two offset gears and one of the two sun gears.
