PROBLEM TO BE SOLVED: To reduce a power loss and tire wear, which are caused by tire slipping associated with vehicle turning traveling of vehicle driving wheels having right and left wheels configured as coaxial double wheels, respectively.SOLUTION: A pair of right and left outside wheels of right and left driving wheels configured as coaxial double wheels, respectively, is driven via a pair of right and left first axles by a first differential gear mechanism. A pair of right and left inside wheels is driven via a pair of right and left second axles concentrically extended as hollow shafts around the first axles, by a second differential gear mechanism sharing an input rotation member with the first differential gear mechanism.SELECTED DRAWING: Figure 1
【課題】左右輪がそれぞれ同軸二重輪とされる車輌駆動輪の車輌旋回走行に伴うタイヤの滑りによる動力損失とタイヤ摩耗を低減する。【解決手段】それぞれ同軸二重輪とされる左右の駆動輪の左右一対の外側車輪を第一の差動歯車機構により左右一対の第一の車軸を経て駆動し、左右一対の内側車輪を前記第一の差動歯車機構と入力回転部材を共通にする第二の差動歯車機構により前記第一の車軸の周りに同心に中空軸として延在する左右一対の第二の車軸を経て駆動する。【選択図】図1
