A power transmission apparatus may include a first motor-generator including a first stator fixed to a first housing, and a first rotor; a second motor-generator including a second stator fixed to a second housing and a second rotor; a first planetary gear set including first and third rotation elements connected to the first rotor and a first wheel, respectively, and a third rotation element; a second planetary gear set including fourth, fifth and sixth rotation elements connected to the second rotor, a second wheel, and the third rotation element, respectively; a first clutch selectively locking up the first planetary gear set by selectively connecting two out of the first to third rotation elements; a second clutch selectively locking up the second planetary gear set by selectively connecting two of the fourth to sixth rotation elements; and a brake selectively fixing the third and sixth rotation elements to a third housing.

Power transmission apparatus for electric vehicle

A mobility hub is composed of a plurality of layers and serves as a terminal of a ground mobility and an air mobility. The mobility hub includes: a ground layer provided with an entrance of the ground mobility; a port layer provided with a taking-off and landing site of the air mobility; and a middle layer provided between the ground layer and the port layer. The middle layer has the ground mobility elevating in a space with the ground layer, is provided with a plurality of connection slots to which the ground mobility is connected, and provides an activity space through the ground mobility if the ground mobility is coupled to the connection slot.
