摘要： A valve control for an internal combustion engine may include a tilt lever, a cam shaft, two cam groups arranged on the cam shaft, a roller bolt arranged on the tilt lever, and an adjusting assembly including a switching pin that engages through the roller bolt. The roller bolt may include two rotatable rollers. The switching pin may be adjustable into a switching position and into a home position. The switching pin may cooperate with a slotted guide of the cam shaft when in the switching position and may have no contact with the slotted guide when in the home position. When the switching pin is in the switching position, the two rollers may be axially adjustable via the adjusting assembly. The switching pin may be axially movable in the roller bolt and the two rollers may be axially movable on the roller bolt into one of two roller positions.

摘要： The present disclosure concerns a slotted guide of a valve train of an internal combustion engine. The slotted guide includes two guide tracks, which cross one another in a crossing region, for guiding a switching pin of a cam follower of the valve train. The two guide tracks have an on-track region, a crossing region, and an off-track region. At least one radial projection, structured and arranged to protrude beyond the slotted guide in a radial direction, is provided in or downstream from the off-track region of at least one guide track.

摘要： A valve train of an internal combustion engine may include a camshaft, first and second cams, a rocker arm assembly having a displacement bolt, which may be adjustable between at least first and second positions in the axial direction and on which at least one cam roller, may be mounted in an axially fixed and rotatable manner, wherein the displacement bolt may be mounted in associated bearing lugs of the rocker arm assembly, a guide contour arranged on the camshaft and having first and second guide tracks, a switching pin, which may be arranged in the displacement bolt and which may optionally engage with the first or second guide track to adjust the displacement bolt between the first and second positions. In the first and second positions, the cam roller may cooperate with the first and second cams, respectively. First and second catch recesses may be provided on the displacement bolt. A catch device may engage with a catch element, which may be biased into the first or second catch recess and which may secure the displacement bolt in the first or second position. The first and second guide tracks may cross one another in a crossing region. A third catch recess may be provided between the first and second catch recesses, wherein a first catch protuberance may be arranged between the first and the third catch recesses, and a second catch protuberance may be arranged between the second and the third catch recesses, wherein the catch element may engage with the third catch recess in the crossing region.

摘要： A method for producing a roller bearing may include threading a cam roller onto a bearing sleeve until the cam roller abuts a first axial flange of the bearing sleeve and inserting a counter holder into the bearing sleeve until the first axial flange of the bearing sleeve abuts a stop of the counter holder. The method may also include heating the bearing sleeve and forming an opposite second axial flange via inserting a forming punch into the bearing sleeve after heating the bearing sleeve. The second axial flange may be formed such that the cam roller is held in the bearing sleeve with radial play and axial play after the bearing sleeve cools down. The method may further include removing the forming punch and the counter holder from within the bearing sleeve.

摘要： A rotor shaft for a rotor of an electric machine is provided. The rotor shaft includes a hollow shaft extending along an axial direction that is rotatably mounted about an axis of rotation, which delimits a hollow shaft interior that can be flowed through by a coolant. Further, the rotor shaft includes a sensor device arranged in the hollow shaft interior for determining a current rotary position or/and current rotational speed of the hollow shaft.

摘要： A valve train may include a camshaft, a cam sleeve adjustable in an axial direction between first and second positions and non-rotatably arranged on the camshaft, a first cam and at least one second cam, a pin and at least one cam follower mounted thereon, a guide contour arranged on the cam sleeve and having first and second guide tracks, and a control pin optionally engaging in the first or second guide track to adjust the cam sleeve between the first and second positions. The at least one cam follower in the first and second positions may interact respectively with the first and second cams. On the camshaft or an internal surface of the cam sleeve, first and second snap-in recesses and a third snap-in recess therebetween may be arranged. A snap-in device having a snap-in element preloaded into the snap-in recesses may be provided, the snap-in recess fixing the cam sleeve in the first or second position. The first and second guide tracks may intersect in an intersection region. Between the first and third snap-in recesses and between the second and third snap-in recesses, first and second snap-in humps may respectively be arranged. The snap-in element may engage in the third snap-in recess when the control pin is in the intersection region.
