Abstract

본 발명은 시린더 블럭의 헤드 높이를 낮추고, 엔진의 성능을 향상시킴과 아울러 연비 및 배출물을 개선하며, 연소실 및 점화 플러그의 설치위치에 제약을 받지 않도록 하는 자동차의 흡, 배기밸브 구동 시스템을 제공하는데 목적이 있다.The present invention provides a vehicle intake and exhaust valve drive system that lowers the head height of the cylinder block, improves engine performance, improves fuel economy and emissions, and is not restricted by the installation location of the combustion chamber and the spark plug. The purpose is to.

이를 실현하기 위하여 본 발명은, 크랭크 축과 연결되어 동력전달이 가능한 풀리를 축의 일측단에 설치하고, 흡기 및 배기행정에 관계하는 캠 프로파일을 보유하는 1쌍의 플레이트를 상기한 축에 일체로 형성함과 아울러 이 플레이트의 외주에 롤러를 보유하는 피스톤을 배치하여 캠 플레이트 하우징에 형성된 유압 실린더내에서 직선이동이 가능하게 하고, 상기한 유압 실린더를 흡, 배기밸브를 구동시키기 위한 밸브 실린더와 관으로 연결하여 유압 전달을 가능하게 하는 자동차의 흡, 배기밸브 구동 시스템을 제공한다.In order to realize this, the present invention provides a pulley which is connected to the crankshaft and is capable of transmitting power at one end of the shaft, and integrally forms a pair of plates on the shaft which hold a cam profile related to the intake and exhaust stroke. In addition, by arranging a piston holding a roller on the outer periphery of the plate, linear movement is possible in the hydraulic cylinder formed on the cam plate housing, and the hydraulic cylinder is connected to a valve cylinder and a pipe for driving the intake and exhaust valves. Provided is an intake and exhaust valve driving system of a vehicle that enables hydraulic transmission by connecting.
