Abstract:
1. A hybrid differential gear device comprising: a first differential gear mechanism distributing driving force from a vehicle to a front tire wheel side and a rear tire wheel side, said first differential gear mechanism including an internal gear as a first element, a sun gear as a second element having an axis the same as an axis of said internal gear, plural planetary gears as a third element disposed between said sun gear and said internal gear, one element selected from the group of said first element, said second element and said third element is an input element and the remaining elements are respectively a first output element and a second output element; a second differential gear mechanism distributing said distributed driving force by said first differential gear mechanism to a right tire wheel and a left tire wheel in said front tire wheel side or said rear tire wheel side; said second differential gear mechanism including a pair of side gears connecting respectively to said right tire wheel and said left tire wheel in said front tire wheel side or said rear tire wheel side, at least one pair of pinion gears engaging with said one pair of side gears, and a plurality of pinion gear shafts rotatably supporting said one pair of pinion gears; and a differential case housing said first differential gear mechanism and said second differential gear mechanism; said pinion gear shafts are supported non-rotatably and movably along a rotational axis of said differential case against one of said first output element and said second output element.
