Abstract
An actuator for a lever that is connected, with a valve or a wastegate or a variable turbine geometry of an exhaust gas turbocharger. The actuator includes a connecting rod between a drive and the lever. The connecting rod is rotatably supported at a location some distance from the lever. The connecting rod is further guided between the support and the lever on a circular arc.
Claims17
An actuator for a lever which is connected to one of a valve, a wastegate, or a variable turbine geometry of an exhaust gas turbocharger, the actuator comprising:
- a drive,
- a connecting rod between the drive and the lever, which connecting rod is rotatably supported at a location at a distance from the lever and which connecting rod is guided between the support and the lever on a circular arc,
- wherein the drive comprises a rotatory drive and a spiral cam or a threaded element;
- wherein the connecting rod is accommodated in a guide element, which is accommodated in a guide block;
- a linear guide that constrains a rotatable support of the connecting rod to linear movement at a location spaced from the guide element.
An actuator system comprising:
- a connecting rod comprising a first end and a second end and defining a longitudinal axis extending therebetween;
- a rotary drive comprising a threaded element, wherein the first end of the connecting rod is connected to the rotary drive such that a rotation of the rotary drive longitudinally displaces the connecting rod;
- a lever, wherein the connecting rod connects to the lever at the second end such that the longitudinal displacement of the connecting rod displaces the lever;
- a guide element comprising a sheath and a protrusion, wherein the connecting rod extends through the sheath;
- wherein the protrusion comprises an arc having a length, a center, and a radius;
- a support block configured to support the guide element, wherein the support block comprises an arcuate contour having a length, a center, and a radius and configured to receive the protrusion;
- wherein the radius of the arc of the protrusion is the same as the radius of the arcuate contour, wherein the arcuate contour comprises a groove.
