Abstract:
An actuating system for use with at least one mode-switching rocker arm device of an internal combustion engine, said at least one rocker arm device having a locking pin, said engine having a camshaft with a camshaft central axis, said actuating system comprising:an elongate actuator shaft having a central axis, said central axis being substantially parallel relative to and spaced apart from the camshaft central axis; at least one actuator lever, said at least one actuator lever being pivotally coupled to said actuator shaft and extending therefrom in a generally radial direction, each said at least one actuator lever being one of in engagement with and disposed proximate to a corresponding said locking pin; a cam follower configured for being pivotally oscillated relative to said central axis of said actuator shaft by an actuator cam lobe of the engine camshaft; and a clutch/brake assembly associated with said actuator shaft and said cam follower, said clutch/brake assembly being operable to selectively transfer pivotal oscillation of said cam follower to pivotal movement of said at least one actuator lever to thereby translate each said locking pin.
