Abstract
A front-rear axle driving torque transmission apparatus, which can improve a degree of freedom with respect to a change of torque distribution to a front wheel driving axle and a rear wheel driving axle by making the best use of a wet-type multiple disc clutch. The front-rear axle driving torque transmission apparatus includes: power input means; differential planetary gear driving means for rotating a front wheel side output shaft and a rear wheel side output shaft at a different rotational speed on the basis of a power inputted by the power input means; and clutch means for locking an operation of the differential planetary gear driving means so that the front wheel side output shaft and the rear wheel side output shaft can be rotated at the same rotational speed. The apparatus has a structure in which the power input means, the differential planetary gear driving means and the clutch means are successively arranged as a unit on an identical axial line in a state of crossing between the rear wheel side output shaft and the front wheel side output shaft arranged on the identical axial line.
