PROBLEM TO BE SOLVED: To provide a vehicle drive device which: has a compressor driven by an internal combustion engine and an air motor driven by air compressed by the compressor; drives a vehicle with the air motor; and can improve energy efficiency in driving the vehicle by efficiently recovering exhaust heat of the internal combustion engine.SOLUTION: A vehicle drive device has an exhaust heat recovery section 27 which is installed on an air passage to supply compressed air from an air tank 23R storing air compressed by a compressor 21 to air motors 4R and 4L and recovers heat energy of exhaust flowing in an exhaust passage 11 of an internal combustion engine. The exhaust passage 11 has a linear section 11a on a passage leading to an opening section open to the atmosphere. The exhaust heat recovery section 27 also has an exhaust heat recovery passage 27a which contacts the linear section 11a of the exhaust passage 11 by being arranged parallel thereto.

    【課題】 内燃機関により駆動されるコンプレッサと、そのコンプレッサによって加圧された空気によって駆動される空気モータとを備え、空気モータによって車両を駆動する車両駆動装置であって、機関の排気熱を効率よく回収し、車両駆動エネルギ効率を高めることができる車両駆動装置を提供する。【解決手段】 コンプレッサ21により加圧された空気が貯蔵される空気タンク23R等から空気モータ4R,4L等へ加圧空気を供給する空気通路の途中に、機関の排気通路11中を流れる排気の熱エネルギを回収する排熱回収部27を設け、排気通路11は、大気に開口する開口部に至る経路中に直線部11aを有し、排熱回収部27は、排熱回収通路27aと排気通路11の直線部11aとを平行に接触させることによって構成する。【選択図】 図1
