PROBLEM TO BE SOLVED: To provide a running drive device of a vehicle, which can be downsized by arranging an input shaft for running and an input shaft for turning with a high space efficiency.SOLUTION: A drive device 1 for running comprises a pair of right and left planetary gear mechanisms 16L, 16R which are connected to a pair of right and left axles 9L, 9R of a vehicle, respectively, an input shaft 14 for running which inputs power from a running drive system 1A to sun gears of the planetary gear mechanisms 16L, 16R to rotate the axles 9L, 9R in the same direction at the same speed, and an input shaft 15 for turning which inputs power from a turning drive system 1B to ring gears of the planetary gear mechanisms 16L, 16R to rotate them in opposite directions to each other and differentiate rotation speeds of the axles 9L, 9R. The input shaft 14 for running and the input shaft 15 for turning are arranged on the same axis, and the input shaft 14 for running is arranged passing through the input shaft 15 for turning which is formed cylindrical.SELECTED DRAWING: Figure 3

    【課題】走行用入力シャフトおよび旋回用入力シャフトをスペース効率よく配置することにより小型化が可能な車両の走行駆動装置を提供する。【解決手段】走行用駆動装置1は、車両の左右一対の車軸9L、9Rにそれぞれ連結された左右一対の遊星歯車機構16L、16Rと、走行駆動系1Aからの動力を遊星歯車機構16L、16Rの太陽ギヤに入力し、車軸9L、9Rを同方向に同速度で回転させる走行用入力シャフト14と、旋回駆動系1Bからの動力を遊星歯車機構16L、16Rのリングギヤに入力して互いに逆方向に回転させ、車軸9L、9Rの回転速度に差を生じさせる旋回用入力シャフト15とを備える。走行用入力シャフト14と旋回用入力シャフト15は同軸上に配置され、走行用入力シャフト14は、円筒状に構成された旋回用入力シャフト15を貫通して配置されている。【選択図】図3
