Internal combustion engine valve drive arrangement

摘要

In an internal combustion engine valve drive arrangement having cam elements which are supported on a camshaft so as to be axially displaceable and having switch gates which are coupled to the cam elements and have gate tracks with track segments and switching segments for displaceing the cam elements, the track segments and the switching segments are formed, at least in part, in partial areas of the switch gates.

1. An internal combustion engine valve drive arrangement having three axially displaceable cam elements (10, 11, 12) with a switch gate (13), coupled to the cam elements (10, 11, 12), the switch gate (13) including gate tracks (14, 15) with track segments (16, 17, 18, 19) and switching segments (20, 21, 22, 23, 24, 25), formed in three different gate elements (26, 27, 28) and being disposed between two cam elements (10, 11) for displacing the cam elements (10, 11, 12) with the two gate elements (26, 27) disposed adjacent the cam elements (10, 11) being formed integrally with the respective adjacent elements (10, 11), the track segments (16, 17, 18, 19) and the switching segments (20, 22, 23, 25) being formed to extend continuously over the gate elements (26, 27, 28) so that, in a partial area, the guide tracks (14, 15) have a double function providing for an insertion or a removal of a switch pin (31, 32) and for a switching of the displaceable cam elements (10, 11, 12).
