CAM ELEMENT FOR A VALVE-GEAR DEVICE |
摘要 |
<p>In a cam element for a valve drive train device of an internal combustion engine having at least one cam comprising at least two partial cams which are arranged next to one another and have a shared base circle phase in at least one angular camshaft range for valve lift switching by displacing their axial position with respect to a cam follower from one of the partial cams to another of the partial cams, the partial cams are angularly displaced in an axially overlapping arrangement. Also, between adjacent partial cams, a circular undercut is formed which has a center that is slightly offset from the rotational axis of the cam element so as to facilitate a switch over of valve actuation from one to another of the adjacent partial cams.</p> |
