  • the camshaft is mechanically driven via a timing chain or timing belt from the crankshaft.
  • a so-called electromagnetic valve train In the case of a fully variable valve train, an "actuator unit" is assigned to each valve or "valve group" of a cylinder.
  • actuator units In a basic type (so-called stroke actuators), a valve or a valve group is associated with an opening and a closing magnet. By energizing the magnets, the valves can be moved axially, ie opened or closed.
  • a control shaft is provided with a cam, wherein the control shaft is pivotable by an electric motor back and forth.

  • the stroke control takes place here via a map-controlled electric motor, to whose rotor a shaft is arranged with a rotatably connected control cam.
  • the motor oscillates or reciprocates and the control cam periodically presses the gas exchange valve into its open position via a pivoting lever.
  • the gas exchange valve is closed by the spring force of a valve spring.
  • an additional spring is attached to the shaft.
  • the forces of valve spring and additional spring are such that during periodic operation of the rotary actuator device according to the position of the gas exchange valve, the kinetic energy is stored either in the valve spring or in the additional spring.

  • This second actuator does not fully open the valve and is used only for small strokes in the range of low engine speeds.
  • the Drehaktuatorvortechnisch is energized so that the shaft pivots only in the direction of the second actuating element, while at high speeds is pivoted exclusively in the direction of the first actuating element. Due to the small stroke, the rotary actuator device advantageously consumes less power at low speeds.
  • the object of the invention is to provide a device for controlling the Hubverlaufes a gas exchange valve, which ensures an improvement in the electrical energy consumption of an actuator.
  • the inventive device for controlling the Hubverlaufes a gas exchange valve comprises a control device (so-called setpoint controller), which drives a drive device (eg the electric motor of a rotary actuator or the electromagnets of an electromagnetic Hubaktuators or the drive means of a Schwenkaktuators) according to a stored desired trajectory, wherein the desired trajectory is such that the ideal swing-out behavior of the energy storage drive element energy storage system (spring-mass-spring system) of the actuator device (in addition to be driven valve unit with gas exchange valve and closing spring) is represented by them.

Due to this regulation then sets in Control behavior in which the electric motor only out of the ideal (calculated) vibration system deviating environmental influences such as friction and gas backpressure by feeding additional drive energy.
  • An ideal swing-out behavior in the sense of the invention is characterized in that a vibration behavior free of friction losses and environmental influences such as gas and gas back pressures is present. Ideally, an ideal vibration behavior corresponds to the calculated vibration curve of the system free of any kind of losses.
  • the invention is a spring-mass-spring system (according to the DE 101 40 461 A1 ) with a valve return spring or opening spring (spring 1), a valve return spring counteracting opening spring (spring 2) and moving in this system between the springs mass (for example: rocker arm, drive cam together with the drive shaft and rotor of the driving electric motor, mass shares of the drive cam in the opening direction acting opening spring and gas exchange valve in addition to mass fractions of the moving closing spring).
  • spring 1 valve return spring or opening spring
  • spring 2 valve return spring counteracting opening spring
  • moving in this system between the springs mass for example: rocker arm, drive cam together with the drive shaft and rotor of the driving electric motor, mass shares of the drive cam in the opening direction acting opening spring and gas exchange valve in addition to mass fractions of the moving closing spring.
  • the device comprises a Drehaktuatorvorraum according to the not previously published DE 103 58 936 ,

Regarding the particular embodiment of such two control tracks having double cam is at this point the content of the DE 102 52 991 A1 included in the disclosure of this application.
  • a plurality of so-called ideal set paths are deposited, each set path describing a different valve lift.
  • FIG. 1 shows the schematic representation of a Drehaktuatorvortechnische for driving a gas exchange valve 2 of an internal combustion engine, not shown.
  • the essential components of this device are, in particular designed as a servomotor electric motor 4 (drive means), a driven by this, preferably two cams 6a, 6b different strokes camshaft 6 (actuator), one with the camshaft 6 on the one hand and with the gas exchange valve 2 on the other operatively connected rocker arm 8 (transmission element) for transmitting movement of the predetermined by the cam 6a, 6b lifting height to the gas exchange valve 2 and one, the gas exchange valve 2 in the closing direction with a spring force acting and designed as a closing spring first energy storage means 10 and, via the camshaft 6 and the drag lever 8, the gas exchange valve 2 acted upon by an opening force and designed as an opening spring second energy storage means 12.

  • the electric motor 4 In order to ensure a low-energy operation of the electric motor 4, which drives the existing gas exchange valve 2 via the camshaft 6, in addition to the optimal design of the counteracting springs (closing spring 10, opening spring 12) and the ideal positioning of rotation and articulation points in the geometry the device itself, the electric motor 4 via a control device 20 according to a desired path SB1, SB2, SB3, which maps the ideal swing-out behavior of the spring-mass-spring system regulated. In particular, this regulation is effected by controlling the rotor profile of the electric motor 4 which drives the at least one actuating element 6, 6a, 6b.
  • the ideal path profile of the rotor which resonates as part of the vibration system, becomes analogous to the ideal vibration curve of the overall system to monitor the actual position of the rotor, an unillustrated displacement sensor is present, which transmits a sensor signal S to the control device 20 or another control device.
  • the electric motor 4 is controlled by the control device 20 such that the at least one gas exchange valve 2 from a first Ventilendlage E1, which corresponds for example to the closed valve position, in a second Ventilendlage E2, E2 ', for example, a partial (E2': Operahub) or maximum opened (E2: full stroke) valve position corresponds, is transferred and vice versa.
  • the system is ideally designed so that the actuator 6, 6a, 6b in the absence of environmental influences (in particular friction and gas back pressure) the way between two end positions R1 - R2 or R1 '- R2' without feeding additional energy, ie without active drive through the Drive device 4, travels and thus engages supportive only in the environmental conditions occurring in practice.
  • the system according to the invention is preferably designed such that in the maximum end positions R1, R2 of the rotor (oscillation end positions at maximum oscillation stroke) each are in a torque-neutral position, in which the forces occurring are in an equilibrium of forces and in which the rotor without application of a additional holding force is held.
  • the rotor thus oscillates from one end position E1, E1 'to the other end position E2, E2' alone due to the forces stored in the energy storage means 10, 12 without feeding an additional energy, such as by the electric motor 4.
  • the ideal decay behavior would be thus that of a perpetuum mobile (infinite constant vibration).
  • the FIG. 2 shows a time chart with nominal paths of the rotor angle of the drive motor of a rotary actuator over time, by means of which a control of the stroke of gas exchange valves according to the invention takes place. Due to the nominal paths, the ideal decay behavior (stroke progression) of a rotary actuator device is determined according to FIG FIG. 1 displayed. Shown are three different nominal paths SB1, SB2, and SB3, wherein the first nominal path SB1 the maximum stroke (rotor oscillates between R1 and R2 back and forth, valve position between E1 and E2 adjusts) of the gas exchange valve represents Tö1 at a given control time with a first valve opening time.
  • the nominal paths SB2 and SB3 each describe partial strokes (rotor oscillates between R1 'and R2' back and forth, valve position between E1 and E2 'adjusts) with shortened valve opening times Tö2 and Tö3.
  • VH_max represents the maximum valve lift
  • VH_teil a possible partial lift that has been set, for example, on the basis of one of the setpoint paths SB2 or SB3.
