Abstract
An electric driving apparatus includes: a housing; an electric machine comprising a motor shaft rotatably supported by the housing; a speed shifting unit for reducing a rotation speed of a rotational driving force of the motor shaft; and a double clutch unit configured to selectively rotationally drive a pair of output shafts by receiving rotational driving force of the speed shifting unit. The speed shifting unit includes: an input gear receiving the rotational driving force of the motor shaft; a speed shifting shaft rotatably supported by the housing; an output gear provided on the speed shifting shaft to rotate together with the speed shifting shaft; and a clutch unit operative to selectively achieve a rotationally constrained engagement between the input gear and the speed shifting shaft.
