Abstract:
A compact planetary differential includes a drive input ring gear having external teeth and a planet gear carrier connected rotationally fixed to the drive input ring gear. First planet gears are located on a first axial side of the planet gear carrier, and second planet gears are located on a second axial side, with the first and second planet gears being arranged in intermeshing pairs, and the planet gear carrier including interface openings. Pin plates include aligned openings for first planet gears and the second planet gears. Pinion shafts extend through these aligned openings and pinion shaft openings in the planet gear carrier. A single one of the first or second planet gears is rotatably supported on each respective one of the pinion shafts. A first sun gear engages with the first planet gears, and a second sun gear engages with the second planet gears.
