【正文】 he current in the clutches 42 of the two torque couplings 24 and 26, the torque can be divided between the two drive wheels 2 and 4 to best acmodate the driving conditions under which the vehicle A operates. For example, if the vehicle A negotiates a left turn, particularly at higher speeds, more torque should be delivered the right drive wheel 2 than to the left drive wheel 4. The clutches 42 in the two torque couplings 24 and 26 are adjusted accordingly. To this end the vehicle A may be provided with accelerometers for determining lateral and longitudinal accelerations and yaw, and hence the severity of turns negotiated, as well as speed sensors for determining the velocities of the two axle shafts 10 and 12, preferably from the antilock braking system for the wheels 2 and 4. More sensors may determine the position of the steering wheel and the temperatures of the clutches 42 and of the wheel service brakes. These sensors produce signals which may be fed to a microprocessor in the vehicle, which microprocessor would determine the best apportionment of torque between the two driving wheels 2 and 4 and control the current in the clutches 42 of the two torque couplings 10 and 12 accordingly. A modified electric drive axle C (FIGS. 6 amp。 7) likewise distributes torque between the left and right drive wheels 2 and 4, apportioning it best to respond to the conditions under which the vehicle A operates. It includes (FIG. 7) an axial flux motor 84, a housing 86 in which the two torque couplings 24 and 26 are enclosed, and a right angle drive 88 located within the housing 86 between the motor 84 and the hubs 40 of the torque couplings 24 and 26. The motor 84 includes a stator 92 and a rotor 94, as well as a motor shaft 96 in which the rotor 94 is mounted. The shaft 96 rotates about an axis Y oriented at a right angle to the axis X. The right angle drive 88 includes a pinion shaft 100 which rotates in the housing 86 about the axis X on antifriction bearings 102. One end of the shaft 100 is connected to the motor shaft 94, while the other end has a beveled pinion 104 on it. In addition, the right angle drive 88 has a connecting shaft 106 which extends between the two hubs 40 and rotates about the axis X. Its ends are fitted to the two drive hubs 40 with mating splines, and the hubs 40 rotate in the housing 86 on bearings 36. The motor 84, when energized, applies torque to and rotates the pinion shaft 100. The pinion 104 at the end of the shaft 100 rotates the spur gear 108 which in turn rotates the connecting shaft 106 and the hubs 40 at the end of it. The hubs 40 deliver the torque to the torque couplings 24 and 26 which function as they do in the drive axle A. Other socalled hook ups are possible for the two torque couplings 24 and 26one, for example, in which the armature 52 of the clutch 42 may be connected to the drive hub 40. Also the positions of the clutch 42 and 44 in each of the torque couplings 24 and 26 may be reversed, with the clutch 42 being connected to the drive flange 46.
