Actuating system for mode-switching rocker arm device

摘要

An actuating system for a mode-switching rocker arm device includes an elongate actuator shaft having a central axis that is parallel with and spaced apart from a central axis of an engine camshaft. An actuator lever extends in a generally radial direction from the actuator shaft to engage a locking pin of the rocker arm device. A cam follower engages and is pivotally oscillated relative to the central axis of the actuator shaft by an actuator cam lobe of the engine camshaft. A clutch/brake assembly is associated with the actuator shaft and the cam follower. The clutch/brake assembly is operable to selectively transfer pivotal oscillation of the cam follower to pivotal movement of the actuator shaft and actuator lever to thereby translate the locking pin and cause the rocker arm device to switch mode.
