Definitions
- the invention relates to an electric combustion engine actuator with a Stell Clean and a Stellmimik for actuating the object StellThates, and in particular relates to gas-conducting actuators, and in this case in particular exhaust gas leading actuators.
- Exhaust gas engine governors are actuators that are fed with exhaust gases from the internal combustion engine. Such actuators are, for example, driven by an electric drive exhaust gas recirculation valves or so-called wastegate valves of turbochargers. Also, an actuator for adjusting the turbine geometry on the exhaust side of a turbocharger is an actuator in this sense.
- the object of the invention is in contrast, to create a powerful electric actuator for a gas-efficient electric actuator.
- the actuating mimic of the internal combustion engine actuator according to the invention has to actuate the object Stell réellees a planetary gear, one planetary gear an eccentrically arranged driver, which actuates the object Stell réelle.
- the planetary gear further comprises a fixed internally toothed ring gear, a coaxial to the ring gear rotatable rotor disc which is driven by an electric rotary drive, and an externally toothed planet gear, which is mounted eccentrically and rotatably on the rotor disc.
- the epicyclic gear From the rotational movement of the rotary drive, which is passed to the rotor disc, the epicyclic gear produces a slightly arcuate or linear movement of the driver. Due to the linear or quasi-linear movement of the driver and the parts driven therewith, the wear of the driver is significantly reduced by the elimination of transverse forces, especially in regular fast adjusting movements.
- epicyclic gear can be configured so that in the positions where high position object holding forces can occur, a high force at low speed is generated. Due to the high reduction ratio in the two end positions, the regulation of the degree of opening can also be carried out very precisely in the region in this position, for example with a low valve opening degree.
- the two end positions of the valve body or the valve disk are those in which high holding forces can occur.
- a very high actuating force is generated by the planetary gear, which is always sufficiently large to break up encrustations even with large valve plates.
- the force is reduced considerably and the speed is increased accordingly.
- the epicyclic can be realized by the epicyclic a high valve stroke, which in turn allows high flow rates. Only these circumstances allow it, an electric one Internal combustion engine actuator for controlling a gas flow containing exhaust gases to use.
- the Planetenrad- outer diameter corresponds to 0.5 times the ring gear inner diameter and corresponds to the eccentricity of the driver, which drives the valve stem, the radius of the planet gear.
- a planetary gear is realized, which provides a linear movement of the driver in a diameter of the ring gear available, which has a high actuating force and a total of a large stroke at the end positions.
- a linear position sensor is provided which detects the linear position of the driver or the object Stellêtes.
- a linear sensor can be used to determine the position of the position object, which directly indicates the linear position of the position object. A computational linearization of the linear sensor signal is no longer required.
- Figure 1 an electric engine actuator, which is designed as an exhaust gas recirculation valve, in longitudinal section in
- FIG. 2 shows the electric combustion engine actuator in FIG. 1 in a middle opening position
- Figure 3 three components of the epicyclic gear of the internal combustion engine actuator
- Figure 4 a diagram of the driver force on the driver path.
- actuator 10 designed as an exhaust gas recirculation valve 10 engine actuator 10 is shown in longitudinal section, as it may be arranged in the course of an exhaust gas recirculation line.
- the actuator 10 has an actuating mechanism 14 for actuating a position object 12, which in the present case is a gas valve 12 with a linearly guided valve stem 26 and a valve disk 28.
- the gas valve 12 may for example also be a wastegate valve of a turbocharger, which is designed in the form of a rotary valve or the like.
- the control mimic 14 has a fixed internally toothed ring gear 16, a to the ring gear 16 coaxial rotatable carrier 18, which is driven by an electric rotary drive 20, an externally toothed planet gear 22 which is eccentrically and rotatably mounted on the rotor disc 18, and a planetary gear 22nd eccentric and fixed associated driver 24, which actuates the object 12 Stell réelle.
- the control mimic 14 is therefore an epicyclic gearbox whose one planet gear 22 has a lever arm 23 with a driver 24.
- the outer diameter of the planet gear 22 is exactly 0.5 times the inner diameter of the ring gear 16. Further corresponds to the eccentricity of the driver 24, so the lever arm length of the lever arm 23 exactly the radius of the planetary gear 22. In this geometric constellation leads the driver 24 exactly a linear movement. The valve rod 26 can therefore be driven directly by the driver 24. There are no transverse forces generated on the valve rod 26, so that the storage of the valve rod 26 wears less.
- the actuator 10 has a fixed linear position sensor 30, which determines the exact linear position of the valve stem 26. In order to determine the linear position of the valve stem 26, no further conversion is required.
- a position sensor is an optical, magnetic, capacitive or another sensor in question.
- the driving force is shown on the driver path.
- the force or entrainment force in the region of the two end positions is a multiple of the force in the largest part between the
