CONTINUOUS VARIABLE VALVE LIFT APPARATUS

摘要

A continuous variable valve lift device can be implemented without modulating the structure of conventional valve train by using the cam shaft of general valve device. A continuous variable valve lift device comprises an input cam(100) equipped on an input shaft, a valve opening/closing unit(600), a rocker arm rotation axis(200), a rocker arm(300) input rotating around the rocker arm rotation axis along with the rotation of the input cam, an output cam(400) which is mounted on the rocker arm and opens/closes the valve opening/closing unit, and a control unit(500) adjusting the location of the rocker arm rotation axis.
