Abstract

본 발명은 타이밍벨트에 작용하는 미세한 진동까지 모두 흡수할 수 있도록 텐션조절장치의 구조를 개량하여 신속한 응답성 및 원가절감에 도움을 주도록 안출한 차량의 타이밍벨트 텐션조절장치에 관한 것으로, 타이밍벨트(10)에 접촉되어 설정된 장력을 주는 동시에 타이밍벨트(10)의 이동방향으로 회전되도록 하는 텐셔너풀리(20)와, 텐셔너풀리(20)를 일단에 굴대설치하는 동시에 엔진블럭(30)의 힌지보울트(40)에 타단을 굴대설치하여 좌, 우 요동되도록 하는 가동텐셔너아암(50)과, 가동텐셔너아암(50)의 하부에 위치되게 힌지보울트(40)에 고정설치되는 고정텐셔너아암(60)과, 가동텐셔너아암(50)과 고정텐셔너아암(60) 사이에 설치하여 가동텐셔너아암(50)의 요동시 자연스럽게 슬립되도록 하는 베어링(70)과, 양단이 가동텐셔너아암(50)과 고정텐셔너아암(60)에 각각 걸리도록 힌지보울트(40)에 끼운뒤 가동텐셔너아암(50)이 탄력있게 벌어지거나 오무라져서 텐셔너풀리(20)로 타이밍벨트(10)의 장력을 조절하도록 하는 토션스프링(80)으로 차량의 타이밍벨트 텐션조절장치를 구성하여, 토션스프링에 의하여 타이밍벨트에 작용하는 미세한 진동까지 모두 흡수할 수 있도록 한다.The present invention relates to a timing belt tension control device of a vehicle which is designed to improve the response structure and cost reduction by improving the structure of the tension control device to absorb even minute vibrations applied to the timing belt. 10) the tensioner pulley 20 and the tensioner pulley 20 to be rotated in the direction of movement of the timing belt 10 while giving a set tension, and at the same time, a hinge bolt of the engine block 30 A movable tensioner arm 50 for mandrelating the other end to the left and right to swing, a fixed tensioner arm 60 fixed to the hinge bolt 40 to be positioned below the movable tensioner arm 50; A bearing 70 installed between the movable tensioner arm 50 and the fixed tensioner arm 60 so as to naturally slip when the movable tensioner arm 50 swings, and both ends of the movable tensioner arm 50 and the fixed tensioner arm 6; The torsion spring (80) is inserted into the hinge bolt (40) so as to be locked to each other and then the tensioner arm (50) is elastically opened or retracted to adjust the tension of the timing belt (10) with the tensioner pulley (20). By configuring the timing belt tension control device of the vehicle, it is possible to absorb all the minute vibration to the timing belt by the torsion spring.
