Abstract
Description
Claims (4)
- 평면형으로 이루어지며 구동을 위한 홈이 형성되어 있는 캠;캠의 홈을 따라 움직임으로써 캠의 회전운동을 직선운동으로 변환시키는 아암;상기한 아암의 끝에 고정장착되어 캠의 홈에 삽입 결합됨으로써 아암과 캠을 연결하여 주며 아암의 마모를 방지하기 위한 캠펠로우핀;변속을 위한 쉬프트 포크 및 인서트팁;아암과 쉬프트 포크를 연결시켜 주며 변속기구의 지지를 위한 고정축; 및쉬프트 포크와 아암의 사이에 설치되어 변속력을 저장함으로써 아암의 회전력을 쉬프트포크에 전달하는 스프링을 포함하여 이루어지는 것을 특징으로 하는 4륜구동 자동차의 부변속기용 변속기구.
- 제 1 항에 있어서,운전자의 의지에 따라 변속하기 위해 모터가 회전하여 캠이 회전하여도 도그 클러치가 치합조건이 되지 안아 변속이 불가능한 경우에는, 상기한 아암은 캠의 트랙을 따라 회전하면서 쉬프트 포크와 아암의 사이에 설치되어 있는 스프링을 벌려서 회전력을 탄성 에너지로 저장하는 것을 특징으로 하는 4륜구동 자동차의 부변속기용 변속기구.
- 제 2 항에 있어서,도그 클러치의 치합조건이 이루어진 뒤에는 쉬프트 포크와 아암의 사이에 설치되어 있는 스프링에 저장되어 있던 탄성 에너지로 인해서 쉬프트 포크가 회전되고, 쉬프트 포크의 회전은 도그 클러치를 움직이게 함으로써 변속이 이루어지는 것을 특징으로 하는 4륜구동 자동차의 부변속기용 변속기구.
- 제 1 항에 있어서,상기한 캠은 소결법으로 제작되는 것을 특징으로 하는 4륜구동 자동차의 부변속기용 변속기구.
