Abstract
A vehicular drive system which includes a first electric motor, a power distributing mechanism (first gear device), a second electric motor, and a step-variable automatic transmission (second gear device), and in which the first electric motor and the power distributing mechanism constitute a first unit, while the second electric motor and the automatic transmission constitute a second unit, and wherein the power distributing mechanism has an output shaft, and the automatic transmission has an input shaft which is connected to the output shaft, whereby a drive force can be transmitted between the first unit and the second unit. The individually prepared first unit and the second unit are assembled together into the vehicular drive system such that the output shaft of the power distributing mechanism and the input shaft of the automatic transmission are connected to each other. Accordingly, the drive system has an improved efficiency of assembling.
