Abstract
A differential apparatus comprises: a differential casing; a first side gear rotatably arranged within the differential casing and connected to the first shaft; a second side gear rotatably arranged within the differential casing in parallel to the first side gear and connected to the second shaft; at least one short pinion gear housed in a bore formed in the differential casing so as to be rotated within the bore and around the first and second side gears together with the differential casing; at least one long pinion gear housed in another bore formed in the differential casing in parallel to and in mesh with the short pinion gear so as to be rotated within the bore and around the first and second side gears together with the differential casing; and a viscous coupling. The first and second side gears are geared to each other through the short and long pinion gears so as to be rotated differentially relative to each other, when the short and long pinion gears are driven by the differential casing. The differential apparatus can generate a torque sensitive differential limiting force uniform both when a torque is transmitted to the first shaft under the condition that the second s…
