To provide a drive wheel drive device enabling turning performance of a vehicle to be adjusted.SOLUTION: A drive wheel drive device which drives a pair of drive wheels of a vehicle comprises: a first drive power source which provides the pair of drive wheels with drive power to drive the same; a differential gear which distributes the drive power of the first drive power source to each of the pair of drive wheels and has a differential case, a pair of side gears stored in the differential case and a pinion gear stored in the differential case so as to engage with a pair of side gears; a second drive power source which provides the drive power to adjust a torque difference between the pair of drive wheels; and a gear mechanism which transmits the drive power of the second drive power source to the differential gear. The gear mechanism has: a rotating member which is installed so as to transmit drive power to the pinion gear of the differential gear and rotatable with the drive power of the second drive power source; and a transmission member which transmits rotation of the rotating member to the pinion gear.SELECTED DRAWING: Figure 1
【課題】車両の旋回性を調整可能にする駆動輪駆動装置を提供する。【解決手段】車両の一対の駆動輪を駆動させる駆動輪駆動装置は、一対の駆動輪を駆動させるための駆動力を与える第1駆動力源と、第1駆動力源からの駆動力を一対の駆動輪のそれぞれに分配するデファレンシャルギアであって、デフケースと、デフケース内に収容された一対のサイドギアと、デフケース内に収容され一対のサイドギアと噛み合うピニオンギアとを備えるデファレンシャルギアと、一対の駆動輪間のトルク差を調整するための駆動力を与える第2駆動力源と、第2駆動力源からの駆動力をデファレンシャルギアに伝達するための歯車機構とを備え、歯車機構は、デファレンシャルギアのピニオンギアに力を伝えるように設けられるとともに第2駆動力源からの駆動力によって回転可能に構成された回転部材と、回転部材の回転をピニオンギアに伝達する伝達部材とを備える。【選択図】図1
