To provide a drive unit of an electric motor-type four-wheel-drive car, which can achieve efficient transmission of a driving force of an electric motor and an improvement in steering property.SOLUTION: A drive unit of an electric motor-type four-wheel-drive car comprises two electric motors, two differential mechanisms, first-eighth connection/disconnection mechanisms, and a sprocket mechanism. Driving forces from the electric motors are distributed and transmitted independently on the right and left sides to front and rear wheels via the connection/disconnection mechanisms, the connection/disconnection states of which are controlled, the sprocket mechanism, and the differential mechanisms. Thereby, torque vectoring is achieved on the right and left sides while differential functions for the front and rear wheels are fulfilled.SELECTED DRAWING: Figure 1

    【課題】電動モータの効率的な駆動力伝達と操舵性の向上を実現可能な電動モータ式四輪駆動車の駆動装置を提供する。【解決手段】電動モータ式四輪駆動車の駆動装置は、2つの電動モータ、2つの差動機構、第1断接機構乃至第8断接機構およびスプロケット機構を具備し、左右独立して電動モータからの駆動力を、断接状態が制御された上記断接機構と上記スプロケット機構と上記差動機構とを介して前輪および後輪に分配および伝達することで、前後輪での差動機能を発揮しつつ左右のトルクベクタリングを実現している。【選択図】 図1
