Claim:
1. A differential system for transmitting a driving power from an input shaft to a pair of output shafts, the differential system comprising: a drive gear for receiving a rotational input from the input shaft; a driven gear defining an axis of rotation and driven by the drive gear, the driven gear defining a central bore and a plurality of slots radially spaced about the axis of rotation and extending from the central bore; a spider member having a central body portion with a plurality of legs extending radially therefrom, each of the plurality of legs having an end portion partially received in one of the plurality of slots; a spider gear supported on each of the plurality of legs of the spider member; at least one cover member coupled to the driven gear to retain the legs in the corresponding plurality of slots; a differential casing enclosing at least the driven gear and the spider member; a bearing disposed between the at least one cover member and the differential casing, the bearing supporting a rotation of the cover member about the axis of rotation relative to the differential casing, an inner circumference of the bearing defining a projected space relative to the axis of rotation; and a side gear connected with each of the pair of output shafts, the side gear configured to be in mesh with each of the spider gears and nested within the projected space of the bearing inner circumference.
