Abstract

구동액슬차동장치는 푸쉬로드(76)위에 미끄러지게 수용되고 이 푸쉬로드위의 플랜지(177)에 대해 정합된 차동 록킹 커브 클러치 칼라(60)용 시프트포오크(72),(74)를 구비하고 있다.
푸쉬로드는 차동캐리어의 보(80)에 미끄러질 수 있게 수용된 단과, 공압동력시프톤(186)를 나삿니로 맞물리는 다른 단을 지닌다.
슬롯(191)이 조절 공구용 푸쉬로드의 나사깍이된 단에 제공되어 있고 록킹스크루(192)가 조절후 푸처로드에 대해 나사각이되어 있다.
공압제어신호 포트틀 포함하는 피스톤 커버(188)가 차동캐리어에 부착되어 있다.
