According to the present invention, a vehicle drive system comprises: a differential gear (1) connected to a drive shaft (120) that is connected to a transmission disconnected from an engine by releasing a clutch by clutch pedal operation; and a damping apparatus (10) generating damping action to the differential gear (1) with damping hydraulic pressure in a release state of the clutch by being supplied with hydraulic pressure to release the clutch as the damping hydraulic pressure. Therefore, shock vibration and noise can be reduced in a repeated power control condition in accordance with release of the clutch, and in particular, an unnecessary fuel efficiency loss can be prevented by a damping effect generated in case of the release of the clutch.
본 발명의 차량 구동계는 클러치 페달 조작에 의한 클러치 해제로 엔진과 연결이 차단되는 변속기에 이어진 드라이브 샤프트(120)와 연결된 디퍼렌셜 기어(1), 클러치를 해제시키는 유압을 댐핑 유압으로 공급받아 클러치의 해제 상태에서 댐핑 유압으로 디퍼렌셜 기어(1)에 댐핑 작용을 발생시키는 댐핑 기구(10)가 포함됨으로써 클러치 해제에 따른 반복적인 동력 단속 조건에서 충격성 진동 및 소음 저감이 이루어지고, 특히 클러치 해제 시에만 발생되는 댐핑 효과로 불필요한 연비손실도 예방되는 특징을 갖는다.
