A drag lever for actuating a gas exchange valve of an internal combustion engine. The drag lever includes an oblong lever body formed of sheet metal material, wherein the lever body has a bottom and side walls integrally formed at an angle of about 90° onto the bottom on both sides. A first end section of the lever body includes a joint socket formed into the bottom between the side walls. The joint socket serves to pivotally moveably support the drag lever on a joint head mounted stationary in the internal combustion engine. A middle section of the lever body is provided with a cam gripping surface, and a second end section of the lever body has a contact surface extending on the bottom. The contact surface serves for actuating the gas exchange valve. The lever body is dimensioned so as to have essentially the same width in a cross section through the joint socket and in a cross section through the middle section. Starting from the first end section of the lever body, the angle of the side walls increases continually to about 90°.
1. A drag lever for actuating a gas exchange valve of an internal combustion engine, the drag lever comprising an oblong lever body formed of sheet metal material,
the lever body having a bottom and side walls integrally formed at an angle onto the bottom on both sides, the bottom extending in a lateral direction between the sidewalls, wherein the lever body has a first end section with a joint socket formed into the bottom between the side walls, wherein the joint socket serves to pivotally moveable support the drag lever on a joint head mounted stationary in the internal combustion engine, the lever body having a middle section with a cam gripping surface, and a second end section with a contact surface extending on the bottom so that the contact surface serves for actuating the gas exchange valve,
the lever body being dimensioned so as to have substantially a common width in a cross section through the joint socket and in a cross section through the middle section, wherein the sidewalls are twisted in a transition area between the middle section and the first end section such that an angle of the sidewalk relative to the lateral direction is 90° at the middle section and the angle of the side walls relative to the lateral direction decreases continually from the middle section toward the first end section of the lever body.
2. The drag lever according to claim 1 , wherein the angle of the side walls is 0° at the first end section.
3. The drag lever according to claim 1 , wherein the joint socket rises between the side walls, and wherein the bottom is located on a side of the cam gripping surface adjacent the joint socket and has a cross section which is arched in a rising direction of the joint socket.
