CONTINUOUSLY VARIABLE VALVE LIFT DEVICE USING 3D CAM FOR VEHICLE

摘要

A continuously variable valve lift device using a 3D cam of a vehicle is provided to enhance durability of the 3D cam by removing eccentric force applied to the 3D cam. A continuously variable valve lift device comprises a camshaft(5) coupled with 3D cams(10,20), a locker arm(40) provided at a lower portion of the camshaft, a driving member connected to a locker shaft(30), and bearings(53,63) for lifting valves(15,25). The valves are connected to the locker arm such that the valves are lifted. The driving member is inserted into the locker shaft connected to one side of the locker arm. The bearings are inserted into a bearing shaft(35) connected to the other side of the locker arm.
