PURPOSE:To improve the running performance by engaging the input gear linked to the front wheel with the output gear fixed to the transmission device for the rear wheels and by transmitting the power with large torque so as to avoid the deficiency of driving force. CONSTITUTION:An output shaft 5b of a mission case 5 and an input shaft 17a of a rear wheel differential gear case 17 are linked together by a propeller shaft 21b which is connected concentrically to a rear wheel transmission shaft 21a penetrating through a front wheel differential gear case 16. On the other hand, an output bevel gear 25 is externally fitted to the rear wheel transmission shaft 21a in the front wheel differential gear case 16, and an input gear 26 engaged with the output bevel gear 25 is linked to a front wheel 1 through a differential gear 27 and a front wheel transmission shaft 22; thus the power is transmitted to the front wheel 1. In this way, the torque loss is reduced in the power transmission from the output shaft of the mission case to the input shaft of the differential gear case for the rear wheels. |
