Abstract: A valve gear has a cam shaft with a firing cam and a braking cam. A first cam follower is allocated to the firing cam with the first cam follower being provided in a firing operation for actuating a gas exchange valve. A second cam follower is allocated to the braking cam with the second cam follower being provided in a braking operation for actuating the gas exchange valve. A changeover device switches between the operations and has a tilting lever mount having a pivotably mounted mounting element on which a tilting lever belonging to the first cam follower and a tilting lever belonging to the second cam follower are pivotably mounted. The tilting lever mount has two mounting screws respectively having a ball head and the ball heads each form a ball joint together with a ball head receiver of the allocated tilting lever.

Abstract: A valve train includes a camshaft which has a cam group having a firing cam and a braking cam. A first cam follower is assigned to the firing cam with the first cam follower being provided in a firing mode for actuating a gas exchange valve. A second cam follower is assigned to the braking cam which is provided in a braking mode for actuating the gas exchange valve. A changeover device is provided to changeover between the firing mode and the braking mode. The camshaft has a separate switching cam which, in at least one operating mode, is provided to act directly on a switching element of the changeover device and which is provided for a direct changeover between the firing mode and the braking mode.

Abstract: A valve drive device for an internal combustion engine is disclosed. The valve drive device has an axially displaceable cam element and an adjusting device with a first engagement element which displaces the cam element axially into a first switching position and a second engagement element which displaces the cam element axially into a second switching position. The adjusting device has a first slotted guide track in which the first engagement element is guided in the first switching position and a second slotted guide track in which the second engagement element is guided in the second switching position. The first engagement element is positively coupled to the second engagement element. The adjusting device includes a triggering device which holds the first engagement element fixedly in the second switching position counter to a restoring force. A method for axial displacement of a rotating cam element is also disclosed.

Abstract: An adjusting device for adjusting valve clearance of a charge-cycle valve of an internal combustion machine is provided. The adjusting device includes a pivoted rocker lever, at one end of which an actuation element is positioned configured to transfer a force to the charge-cycle valve. A transmission element is attached to the actuation element at an opposite end to the charge-cycle valve of which a sleeve area is positioned, which is used to support the transmission element regarding the actuation element. A method for adjusting valve clearance of a charge-cycle valve of an internal combustion machine using an adjusting device is also provided.
