Abstract
A switchable valve train for gas-exchange valves of internal combustion engines with a rocker arm device (), in which a rocking motion about a rocker arm axis () can be introduced by at least one cam (), one tappet, or the like, wherein this rocking motion can be transmitted to at least one valve (). The rocker arm device () is formed from at least one cam lever part () in working connection with the cam () and a valve lever part () in working connection with the valve (), which are supported so that they can rock about the rocker arm axis (). A coupling device is constructed between the cam lever part () and the valve lever part (), in order to selectively engage and disengage the transmission of the rocking motion.
