Abstract
A differential gear train for a wheeled vehicle includes a first housing, a first cover, a second housing, a second cover, a plurality of pinions, a first sun gear, and a second sun gear. Thus, the first sun gear drives the second sun gear by provision of the pinions at different positions so that the second propeller shaft in the second sun gear is directly driven by the first propeller shaft in the first sun gear by transmission of the first sun gear, the second sun gear and the pinions to perform a direct transmission exactly without incurring deflection, thereby enhancing the precision of transmission.
