Abstract
The present invention relates to a switchable actuation device () for a gas exchange valve. The switchable actuation device () comprises a two-piece rocker arm (). Said rocker arm comprises a first rocker arm portion (), which is mounted pivotably about a rocker arm shaft () and to which a bearing sleeve () is fastened concentrically with the rocker arm shaft (), and a second rocker arm portion () mounted pivotably on the bearing sleeve (). Furthermore, both the first and the second rocker arm portions () each comprise a cut-out (), wherein a locking element () of a coupling device () of the switchable actuation device () can optionally be brought into and out of engagement with the two cut-outs (). An actuation of the poppet valve, preferably a change between a closed position and an open position of the poppet valve, is interrupted if the locking element () is not in engagement with the two cut-outs (). The invention also relates to an internal combustion engine () and a motor vehicle ().
