Abstract

목적: 본 발명의 목적은 V형 엔진의 실린더헤드에 축받이한 2개의 캠축의 각 스프로켓에 감기는 체인에 일정 장력을 부여하는 텐셔너자체의 강성향상 및 실린더헤드의 텐셔너 부착부위의 파손을 회피할 수 있어 콤팩트화를 달성할 수 있는 V형 엔진의 동밸브 구동장치를 실현하는데 있다.PURPOSE: The object of the present invention is to improve the rigidity of the tensioner itself, which imparts a constant tension to the chain wound on each sprocket of the two camshafts supported by the cylinder head of the V-type engine, and to avoid the damage of the tensioner attachment part of the cylinder head. In order to achieve compactness, a copper valve driving device for a V-type engine can be realized.

구성: 이목적을 달성하기 위하여 본발명은 V자형상 실린더블록의 2개의 실린더뱅크에 각각 부착하여 설치한 실린더헤드에 각각 2개의 캠축을 축받이하여 설치한 V형 엔진의 동밸브 구동장치에 있어서 상기 실린더헤드의 헤드볼트가 삽통되는 볼트 삽통용 보스부의 볼트삽통방향 선상에 위치시켜서 상기 2개의 캠축에 각각 스프로켓을 부착하여 설치하고, 이들 각 스프로켓에 체인을 감아서 설치하고, 이 체인에 일정장력을 부요하는 텐셔너를 설치하여, 상기 실린더헤드에 상기 텐셔너의 텐셔너 본체가 끼워지는 본체끼움용 보스부와 상기 텐셔너의 텐셔너지지부가 부착되는 지지부 부착용 보스부를 설치함과 동시에 상기 본체 끼움용 보스부를 상기 지지부 부착용 보스부에 의해 상기 볼트 삽통용 보스부에 일체적으로 연결하여 설치한 것을 특징으로 한다.Composition: In order to achieve this purpose, the present invention is a copper valve driving apparatus of a V-type engine provided with two camshafts respectively installed in a cylinder head attached to two cylinder banks of a V-shaped cylinder block. The head bolt of the head is placed on the bolt insertion direction line of the bolt insertion boss section through which the head bolt is inserted, and the sprockets are attached to each of the two camshafts, respectively. Install a tensioner to install a main body fitting boss portion into which the tensioner main body of the tensioner is fitted, and a support portion attachment boss portion to which the tensioner support portion of the tensioner is attached, and at the same time, the main body fitting boss portion is provided with the support portion attachment boss. And integrally connected with the bolt insertion boss by means of the do.
