ABSTRACT:
Turbine powered, self-propelled vehicles utilizing multiple electric motors in sets to comprise part of a novel modular electric powertrain drive system. This novel powertrain system is particularly applicable to larger weight class tracked military vehicles, such as an M-1 tank. However, other large or smaller weight class turbine powered vehicles, are candidates including both track and wheel driven types, as well as certain airborne type vehicles such as helicopters and ground-effect vehicles. The modular powertrain drive system hereof basically comprises a plurality of electric high speed drive motors and also of electrical power generator devices, such as alternators, arranged to be commonly driven by the turbine's effective output shaft. The generator devices will supply the requisite power to the plurality of high speed, heavy duty, electric drive motors circumferentially arranged, each with a drive pinion gear to operatively engage the periphery of a sun gear or ring gear fixed on an output drive shaft disposed concentrically to sets of the circumferentially arranged drive motors and their pinion gears. Preferably there are two sets of the multiple drive motors which together with their output drive shafts collectively act as final output drives for the various type vehicles. The unique concept embodies said plural motors which have relatively low torque, so that their collective high speed input is converted to relatively low speed but high torque output. Torque-speed changes are accomplished through power controller devices by which the operator can vary the electrical energy delivered collectively by the generator devices to the collective sets of drive motors.
