VARIABLE VALVE LIFT APPARATUS

摘要

PURPOSE: A variable valve lift device is provided to simplify structure and to be used without the excessive design change of the general valve train. CONSTITUTION: A variable valve lift device comprise a drive eccentric cam(12), an amplification rotating arm(20), a variable eccentric cam(32), an output cam(90), a binding link(70), and a connecting unit. The drive eccentric cam is axis-connected to the drive shaft. The amplification rotating arm rotates along the drive eccentric cam. The output cam is rotatably formed in the drive shaft. The variable eccentric cam is axis-connected with a control axis which is parallel to the driving shaft. The binding link rotates along the variable eccentric cam.
