Abstract:
A front-rear axle driving torque transmission apparatus, comprising: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 said differential planetary gear driving means so that said front wheel side output shaft and said rear wheel side output shaft can be rotated at the same rotational speed, said power input means, said differential planetary gear driving means and said clutch means being 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, wherein said differential planetary gear driving means and said clutch means are arranged in a housing which crosses between the rear wheel side output shaft and the front wheel side output shaft arranged on the identical axial line, and is rotated around the identical axial line integrally with said power input means, and the housing rotating integrally with said power input means is composed of a clutch housing of said clutch means and a power input housing which are coupled together by a plurality of bolts, said power input housing including a power input carrier of said differential planetary gear driving means, and said power input housing and said power input carrier being a one-piece component of the transmission apparatus.
