A variable valve drive for a lifting valve, in particular for a charge-exchange valve of an internal combustion engine, which is periodically movable between a closed position and an open position indirectly by way of a cam of a camshaft, comprising a switchable rocker lever arrangement for the actuation of the lifting valve, having a transmission rocker lever and a valve rocker lever which are mounted so as to be pivotable on different rocker lever axles (13, 23), which rocker lever axles are each parallel to the camshaft axis, wherein the valve rocker lever is, at a first end, in operative contact with the lifting valve and has, at a second end, a roller, wherein the transmission rocker lever is, at a first end, in engagement with a cam of the camshaft and is, at a second end, operatively connected via a contour surface to the roller of the valve rocker lever, such that a rocking movement of the transmission rocker lever generates a rocking movement of the valve rocker lever, during which the roller of the valve rocker lever rolls on the contour surface; and an actuating device for the switching of the rocker lever arrangement, by means of which actuating device the contour surface is rotatable around the rocker lever axle of the transmission rocker lever by means of a planetary gearing so as to generate a displacement of a rolling region of the roller of the valve rocker lever on the contour surface (16; 516), characterized a) in that the transmission rocker lever has: a1) at least one planet gear of the planetary gearing, which is guided by a planet carrier element of the transmission rocker lever, wherein the planet carrier element has the first end, which is in engagement with a cam of the camshaft; and a2) a ring gear of the planetary gearing, which has the contour surface on the outer circumferential side and engages into the at least one planet gear; and b) in that a sun gear of the planetary gearing is connected rotationally conjointly to a shaft which is able to be rotated by the actuating device. a switchable rocker lever arrangement for the actuation of the lifting valve, having a transmission rocker lever and a valve rocker lever which are mounted so as to be pivotable on different rocker lever axles (13, 23), which rocker lever axles are each parallel to the camshaft axis, wherein the valve rocker lever is, at a first end, in operative contact with the lifting valve and has, at a second end, a roller, wherein the transmission rocker lever is, at a first end, in engagement with a cam of the camshaft and is, at a second end, operatively connected via a contour surface to the roller of the valve rocker lever, such that a rocking movement of the transmission rocker lever generates a rocking movement of the valve rocker lever, during which the roller of the valve rocker lever rolls on the contour surface; and an actuating device for the switching of the rocker lever arrangement, by means of which actuating device the contour surface is rotatable around the rocker lever axle of the transmission rocker lever by means of a planetary gearing so as to generate a displacement of a rolling region of the roller of the valve rocker lever on the contour surface (16; 516), characterized a) in that the transmission rocker lever has: a1) at least one planet gear of the planetary gearing, which is guided by a planet carrier element of the transmission rocker lever, wherein the planet carrier element has the first end, which is in engagement with a cam of the camshaft; and a2) a ring gear of the planetary gearing, which has the contour surface on the outer circumferential side and engages into the at least one planet gear; and b) in that a sun gear of the planetary gearing is connected rotationally conjointly to a shaft which is able to be rotated by the actuating device. a) in that the transmission rocker lever has: a1) at least one planet gear of the planetary gearing, which is guided by a planet carrier element of the transmission rocker lever, wherein the planet carrier element has the first end, which is in engagement with a cam of the camshaft; and a2) a ring gear of the planetary gearing, which has the contour surface on the outer circumferential side and engages into the at least one planet gear; and a1) at least one planet gear of the planetary gearing, which is guided by a planet carrier element of the transmission rocker lever, wherein the planet carrier element has the first end, which is in engagement with a cam of the camshaft; and a2) a ring gear of the planetary gearing, which has the contour surface on the outer circumferential side and engages into the at least one planet gear; and b) in that a sun gear of the planetary gearing is connected rotationally conjointly to a shaft which is able to be rotated by the actuating device.
