FIELD: engine building.
SUBSTANCE: invention can be used in valve drives of internal combustion engines. Adjustable valve drive (10) with cam system (14) with an adjustable position for an internal combustion engine includes shaft (12), cam base (22), force transfer mechanism (16) with lever axis (42) and force transferring element (40), actuator (24), (26) for movement of cam base (22) along the axis, and support device (46). Cam base (22) is located on shaft (12) without the possibility of rotation and with the possibility of displacement along the axis, and it contains first cam (28) and second cam (29). Force transfer mechanism (16) is described with lever axis (42) and force transferring element (40), in particular, a rolling lever or a rocker arm, made with the possibility of rotation around lever axis (42) and, depending on the axial position of cam base (22), selectively kinematically connected between first cam (28) and a valve of gas distribution mechanism (18, 20) of the internal combustion engine or between second cam (29) and the valve of gas distribution mechanism (18, 20). Support device (46) at least partially embraces lever axis (42), and actuator (24), (26) is installed on it. Support device (46) embraces lever axis (42) with several parts. Alternatively, support device (46) contains the first bearing element and the second bearing element, which are attached to each other, and each of which forms part of a composite mount, in particular, a mount semiring of lever axis (42). A vehicle is disclosed.
EFFECT: prevention of undesired bends capable of forming deformations of a lever axis under the action of forces for movement of a base, occurring during operation of actuators.
