Abstract

4륜 구동 자동차의 제2동력 전달 계통의 액슬 디퍼렌셜은 제2구동 휠에 전달되는 토크를 제어하기 위해 평범하게 또는 개별적으로 작동될 수 있는 개별 변조식 액슬 클러치를 포함한다. 디퍼레셜은 베벨 기어 세트를 구동시키는 입력 축과, 변조식 클러치 및 좌, 우 축력 축을 포함한다. 변조식 클러치 각각은 제1 및 제2 삽입된 복수의 클러치 플레이트를 가지는 디스크 팩 클러치 어셈블리와, 볼램프 작동기 및 삽입된 클러치 플레이트에 압축력을 작용시키는 볼 램프 작동기를 작동시키는 전자기 코일을 포함하다. 좌, 우 제2휠 슬립을 제어하기 위한 작동 프로그램은 디퍼렌셜로 사용될 수 있다.
