ABSTRACT:
A reversible power transmission having a pair of axially spaced selectively actuable brakes each including fixed stator disks and rotor disks. Two ring gears each have gear teeth on inner and outer surfaces with the outer teeth enmeshed with inner teeth on the rotor disks. An input shaft carries a driving sun gear. An output shaft is aligned with the input shaft. A cage carried by the output shaft has two arrays of idler pinion gears journaled in the cage with the first array driven by the sun gear and driving the second array. Each pinion of the first array is enmeshed with teeth on the inside of one of the ring gears, and each pinion of the second array is enmeshed with teeth on the inside of the other ring gear.
