Variable valve gear for an internal combustion engine of a motor vehicle, in particular of a commercial vehicle, having: a first exhaust valve; a camshaft; a cam carrier which is arranged on the camshaft in a manner which prevents relative rotation and allows axial movement between a first axial position and a second axial position and has a first cam and a second cam, wherein the first cam and the second cam are arranged offset in a longitudinal direction of the camshaft; and a first transmission device which, in the first axial position of the cam carrier, is in operative connection between the first cam and the first exhaust valve, and, in the second axial position of the cam carrier, is in operative connection between the second cam and the first exhaust valve; wherein the first cam is designed for a normal mode of the internal combustion engine, in which the first cam keeps the first exhaust valve open in the exhaust stroke; and the second cam is designed for an engine braking mode of the internal combustion engine, in which the second cam initially keeps the first exhaust valve closed in the compression stroke and/or in the exhaust stroke and opens the first exhaust valve before reaching a top dead centre of a piston movement; characterized in that the cam carrier has a third cam which is designed in the manner of the first cam and has a cam-less section, wherein the first cam, the second cam, the third cam and the cam-less section are arranged offset in a longitudinal direction of the camshaft, and furthermore having: a second exhaust valve; and a second transmission device which, in the first axial position of the cam carrier, is in operative connection between the third cam and the second exhaust valve, and, in the second axial position of the cam carrier, keeps the second exhaust valve closed because of the design of the cam-less section. a first exhaust valve; a camshaft; a cam carrier which is arranged on the camshaft in a manner which prevents relative rotation and allows axial movement between a first axial position and a second axial position and has a first cam and a second cam, wherein the first cam and the second cam are arranged offset in a longitudinal direction of the camshaft; and a first transmission device which, in the first axial position of the cam carrier, is in operative connection between the first cam and the first exhaust valve, and, in the second axial position of the cam carrier, is in operative connection between the second cam and the first exhaust valve; wherein the first cam is designed for a normal mode of the internal combustion engine, in which the first cam keeps the first exhaust valve open in the exhaust stroke; and the second cam is designed for an engine braking mode of the internal combustion engine, in which the second cam initially keeps the first exhaust valve closed in the compression stroke and/or in the exhaust stroke and opens the first exhaust valve before reaching a top dead centre of a piston movement; characterized in that the cam carrier has a third cam which is designed in the manner of the first cam and has a cam-less section, wherein the first cam, the second cam, the third cam and the cam-less section are arranged offset in a longitudinal direction of the camshaft, and furthermore having: a second exhaust valve; and a second transmission device which, in the first axial position of the cam carrier, is in operative connection between the third cam and the second exhaust valve, and, in the second axial position of the cam carrier, keeps the second exhaust valve closed because of the design of the cam-less section. a second exhaust valve; and a second transmission device which, in the first axial position of the cam carrier, is in operative connection between the third cam and the second exhaust valve, and, in the second axial position of the cam carrier, keeps the second exhaust valve closed because of the design of the cam-less section.
