The DeDion-Axle (Albert DeDion, 1899) represents a special form of a driven rigid axle, where the two wheel carriers are linked by a rigid carrier but the differential gear is fixed to the body and linked to the wheels via drive shafts. In this axle design, the wheel-load difference occurring in rigid axles with integrated differentials, in response to the propeller shaft torque is absent and the amount of unsprung masses is smaller, but these advantages are offset by the disadvantage of considerable design effort.
