SWING ARM AND VARIABLE VALVE LIFT DRIVE DEVICE WITH SWING ARM

摘要

Disclosed is a swing arm. The swing arm comprises a swing arm body (1), a first rotation center (11) and a second rotation center (12) are set on the swing arm body (1), when the swing arm swings around the first rotation center (11), a valve rod is driven to perform linear reciprocating motion to open or close a valve, and when the swing arm swings around the second rotation center (12), a position of the first rotation center (11) is adjusted. Further disclosed is a variable valve lift drive device with the swing arm. The variable valve lift drive device can implement continuous variations of the valve lift, prolong the service life of parts, and reduce the manufacturing cost and fuel consumption of a motor.
