Abstract
A plural output differential drive system provides plural outputs that are differentially related to each other. Three or more output shafts are driven from a single input shaft, each output shaft being differentially linked with the other output shafts. The entire differential drive arrangement is contained within a single housing. The output shafts of the plural output differential will transfer power in applications wherein equal distribution of torque is required at three or more outputs. The input shaft may be arranged to be coaxial with the output shafts, or may be at any other angle, including orthogonal thereto. Typical applications include powering three or more live axles on vehicles, providing rotary power for developing equal torques for simultaneously tightening multiple bolts, and generating equal forces on the gripper fingers of robotic hands. In addition, the outputs can be applied to leveling devices where three or more legs must apply equal pressures on a surface. Differential action is made available to each of the tandem wheels of a truck vehicle, in one embodiment of the invention.
