To provide a driving device of a four wheel drive vehicle which can control driving force to be transmitted to left and right driving wheels at front and rear sides only by output control of left and right electric motors without using a front-rear difference rotation absorption mechanism such as a coupling.SOLUTION: A driving device of an electric motor type four wheel drive vehicle includes: a first motor and a second motor provided at one of a front wheel side and a rear wheel side; a first differential mechanism connected to the first motor; a second differential mechanism connected to the second motor; and a propeller shaft which transmits power between the front wheel side and the rear wheel side. The first differential mechanism distributes output torque of the first motor to a left wheel at one of the front wheel side and the rear wheel side and the other of the front wheel side and the rear wheel side. The second differential mechanism distributes output torque of the second motor to a right wheel at one of the front wheel side and the rear wheel side and the other of the front wheel side and the rear wheel side.SELECTED DRAWING: Figure 1

    【課題】カップリングのような前後差回転吸収機構を用いることなく、左右の電動モータの出力制御のみにより前後左右の各駆動輪へ伝達する駆動力を制御可能な、四輪駆動車の駆動装置を提供する。【解決手段】電動モータ式の四輪駆動車の駆動装置は、前輪側及び後輪側のうちの一方側に設けられた第1のモータ及び第2のモータと、第1のモータに接続された第1の差動機構と、第2のモータに接続された第2の差動機構と、前輪側と後輪側との間で動力を伝達するプロペラシャフトと、を備え、第1の差動機構は、前輪側又は後輪側のうちの一方側の左輪と、前輪側又は後輪側のうちの他方側と、に第1のモータの出力トルクを分配し、第2の差動機構は、前輪側又は後輪側のうちの一方側の右輪と、前輪側又は後輪側のうちの他方側と、に第2のモータの出力トルクを分配する。【選択図】図1
