Abstract

구조적으로 간단하고 오일의 리크특성을 향강시켜 타이밍 벨트의 장력변화에 따라 적절히 장력을 조절할 수 있도록 하기 위하여 엔진블럭에 고정설치되는 중공상의 몸체와: 이 몸체의 내측에 슬라이드 가능하게 설치되며 일측단이 텐셔너 아암과 접촉하는 로드부재와, 상기한 몸체 내측의 일정한 위치에 배치되며 좌우로 연통하는 통로가 형성된 고정부재와, 몸체의 타측단에 제3스프릭을 통하여 탄성적으로The hollow body is fixed to the engine block so as to be simple in structure and to improve the oil leakage characteristics so that the tension belt can be properly adjusted according to the tension change of the timing belt. A rod member contacting the tensioner arm, a fixing member disposed at a predetermined position inside the body and having a passage communicating from side to side, and elastically through a third sprinkler at the other end of the body;

설치되는 가동부재를 포함하며, 강기한 통로를, 타이밍 벨트의 장력이 클때 차단하고 작을때 개방하는 체크밸브수단에 의허 로드부재와 고정부재 사이에 형성되는 제1유압실과, 상기한 고정부재와 가동부재A first hydraulic chamber formed between the rod member and the fixing member by a check valve means for blocking the rigid passage when the tension of the timing belt is large and opening when the tension belt is large, and movable with the fixing member. absence

사이에 형성되는 제2유압실의 오일이, 타이밍 벨트의 장력이 클때 고정부재와 몸체 사이로 흐르고 타이밍 벨트의 장력이 작을때 통로를 통하여 흐르도록 하여 힘의 평형을 유지하는 자동차의 타이밍 벨트 장력 조절장치를 제공한다.The timing belt tension control device of a vehicle which maintains an equilibrium of force by allowing the oil of the second hydraulic chamber formed therebetween to flow between the fixing member and the body when the timing belt tension is large and through the passage when the timing belt tension is small. To provide.

Claims

A hollow body fixedly mounted to the engine block, a rod member slidably installed inside the body and having one end thereof in contact with the tensioner arm, and a passage disposed at a predetermined position inside the body and communicating from side to side A fixed member and a movable member elastically installed at the other end of the body through a third spring, and fixed with the rod member by a check valve means for opening and closing the rigid passage when the timing belt tension is large. The forming sinus between the members causes a passage between the first hydraulic chamber and the oil of the second hydraulic chamber formed between the fixed member and the movable pushing member to flow between the fixing member and the body when the timing belt is large and the tension of the timing belt is small. A timing belt tensioning device for a vehicle that flows through to maintain a balance of forces.

2. The timing belt tension adjusting device for an automobile according to claim 1, wherein the tech valve means includes a check ball in contact with the passage, a first spring for pressing the check ball into the passage, and a retainer for supporting the first spring. .
