ABSTRACT:
A power transmission for automotive vehicles includes a trans-axle housing formed therein with first, second and third compartments which are in open communication with each other and store therein an amount of lubricating oil, a change-speed gear transmission mounted within the first compartment, a first transfer gear mechanism mounted within the second compartment and in drive connection with the gear transmission, and a second transfer gear mechanism mounted within the third compartment and in drive connection coaxially with the first transfer gear mechanism. For sufficient lubrication of the second transfer gear mechanism, an oil pump is mounted within the first compartment to be driven by the output drive power from the gear transmission and is connected to a communication passage extending to the third compartment through the second compartment to introduce lubricating oil discharged from the oil pump into the third compartment.
