CONTINUOUS VARIABLE VALVE LIFT DEVICE AND OPERATION LOGIC

摘要

PURPOSE: A continuous variable valve lift device and operation logic are provided to enable exact advanced angle adjustment and improve advanced angle effect by fixing an advanced angle lever and a joggling cam on the same shaft. CONSTITUTION: A continuous variable valve lift device comprises a vibration outer wheel(300), a rocker arm(400), an advanced angle lever(500), and a joggling cam(700). The vibration outer wheel is vertically moved by the rotation of a roller link(200) connected to a rotation shaft(100). The rocker arm is vertically moved by the vibration outer wheel. The advanced angle lever is connected to the rocker arm and selects the advanced angle or rearward angle. The joggling cam rotates based on the fixed shaft by the vertical movement of the joggling cam to open and close a valve. The joggling cam engages with the rocker arm. The roller tank is contacted with the main surface of the vibration outer wheel.
