Summary: | To provide a vehicle which is driven by using rotating force outputted by a motor as driving force and capable of suppressing overheating of the motor and effectively utilizing thermal energy collected while cooling the motor.SOLUTION: A driving device 20 includes: a motor 30 for outputting rotating force used as a driving power source for driving wheels 24; and a speed reduction mechanism part 40 having a speed reduction mechanism 44 operated by receiving the rotating force outputted by the motor 30 in a speed reduction mechanism housing 42. The speed reduction mechanism housing 42 has oil in it. A heat medium flow channel 80 capable of circulating a heat medium is provided around the motor 30 and around the speed reduction mechanism part 40. The heat medium flow channel 80 can circulate the heat medium in such a manner that a flow of the heat medium from a motor 30 side to a speed reduction mechanism part 40 side and a flow of the heat medium from a speed reduction mechanism part 40 side to a motor 30 side are alternately formed.SELECTED DRAWING: Figure 2
【課題】モータから出力された回転力を動力として駆動する車両において、モータの過熱を抑制しつつ、モータの冷却に伴って改修された熱エネルギーを有効利用可能な車両の提供を目的とした。【解決手段】駆動装置20は、駆動輪24の動力源となる回転力を出力するモータ30と、モータ30から出力された回転力を受けて作動する減速機構44を減速機構ハウジング42内に備えた減速機構部40とを有する。減速機構ハウジング42内には、オイルが収容されている。モータ30の周囲、及び減速機構部40の周囲には、熱媒体を流通可能な熱媒体流路80が設けられている。熱媒体流路80は、モータ30側から減速機構部40側に流れる熱媒体の流れと、減速機構部40側からモータ30側に流れる熱媒体の流れが交互に形成されるように熱媒体を流通できる。【選択図】図2 |
