Definitions

  • Electromechanical drive for controlling and regulating a throttle valve acting as a flow modulator in a pipe
  • the invention relates to an electromechanical drive for controlling and regulating a throttle valve functioning as a flow modulator with an axis in a tube.
  • EP 0 647 348 B1 proposes an electromechanical drive with a rotor and a stator, the rotor being connected directly to the axis of the throttle valve. This makes it possible for the flow modulator to reach frequencies in the order of a few hundred hertz.
  • the invention is based on the object of providing a drive for controlling and regulating a throttle valve functioning as a flow modulator, which is robust and is inexpensive and which enables higher accelerations by reducing the mass to be moved and thereby a significant increase in the usable frequency range.
  • the drive should have a low power consumption and enable control of the vibration behavior.
  • the invention is based on the basic idea of providing a drive in which a translatory movement is generated, which is converted into a tilting movement in the region of the axis of the throttle valve.
  • the translational movement is generated in a vibration generator, in which one end of a rod is set in vibration, the vibration can be generated in the form of an up and down movement or a back and forth movement.
  • This translational movement is converted into a tilting movement in the region of the axis of the throttle valve, the movement being understood to mean an oscillation of approximately 3 to 10 degrees around a rest position. That is, the throttle valve performs a controlled or regulated flutter movement.
  • a coil with an iron core, to which an active counter bearing is assigned, can be used as the vibration generator.
  • the active counter bearing can be a spring of a coil or a magnet.
  • Pneumatic, hydraulic solutions are also conceivable.
  • Compressible media e.g. a gel pad is also possible.
  • a piezo component to which a counter bearing is assigned, can be used as the vibration generator.
  • the counter bearing can also be designed as a piezo block.
  • the vibration is converted into a tilting movement by the appropriate connections in the region of the axis.
  • the rod is supported in such a way that a lever is created and the other end of the rod is connected to the axis of the throttle valve via an eccentric.
  • Another possibility is to connect the rod to the axis of the throttle valve via gear wheels.
  • the rod When the rod moves back and forth, the rod is connected to the axis of the throttle valve via a rocker arm.
  • the tilting movement of the throttle valve can be limited by end stops.
  • the vibration behavior can be controlled and a targeted influence can be exerted on the vibration behavior by a damping element which is arranged on the rod.
  • This damping element can be designed passively or actively. By actively controlling the damping element, age-related changes can be eliminated.
  • the following advantages are achieved by the drive according to the invention: only small masses have to be moved. This enables faster movements and accelerations. It is much cheaper than the drives known from the prior art. There are no storage problems. A larger frequency range is possible. The vibration can be influenced in a targeted manner by means of adjustable damping.
  • the drive according to the invention has a low current consumption.
  • a pipe is to be understood as any pipe through which a fluid flows and whose flow is to be influenced by the throttle valve acting as a flow modulator. This is e.g. B. the case with exhaust pipes.
  • Another application is the intake pipe of an internal combustion engine.
  • FIG. 1 shows a schematic illustration of a drive with a vibration generator with up and down movement in a side view
  • FIG. 2 shows the drive of FIG. 1 in a top view
  • FIG. 3 shows an exemplary embodiment of the vibration generator with piezo components
  • FIG. 4 shows an exemplary embodiment of the vibration generator with a coil and a spring
  • FIG. 5 shows an embodiment of the vibration generator with two coils
  • FIG. 6 shows a schematic illustration of a drive with a vibration generator with a back and forth movement
  • Figure 7 shows another embodiment of the drive with a vibration generator with a back and forth movement
  • Figure 8 shows an embodiment of the drive with a gear.
  • FIG. 1 shows a tube 1 in which a throttle valve 2 with an axis 3 is arranged. On the axis 3, an eccentric 4 is attached, which is connected to a rod 5.
  • the rod 5 is stored in a bearing 6.
  • the other end of the rod 5 is located in a vibration generator which consists of a coil 8 with an iron core 9 and a coil 10 with an iron core 9a and a spring 11.
  • An oscillation of the rod 5 is generated by the oscillation generator.
  • the bearing 5 balances the rod 5 such that the vibration generator only has to work against the damping of the damping element 7. This mass distribution enables high accelerations / speeds.
  • Figure 2 shows the drive of Figure 1 in plan view.
  • the reference symbols have the same meaning as in FIG. 1.
  • the throttle valve 2 with the axis 3 is arranged in the tube 1.
  • the axis 3 is mounted outside of the tube 1 in a bearing 12.
  • the damping element 7 can be regulated by a controller 13.
  • a regulator 14 regulates the vibration generator.
  • FIG. 3 shows an oscillation generator for the up and down movement.
  • the rod 5 is located at one end between two piezo components 20 and 21, which cause the rod 5 to oscillate up and down.
  • the rod is caused to oscillate up and down by a coil 8 with an iron core 9 and a spring 11 as an active counter bearing.
  • FIG. 5 shows a vibration generator for the up and down movement with a coil 8 with an iron core 9 and a coil 10 with an iron core 9a as an active counter bearing.
  • FIG. 6 shows a vibration generator for a back and forth movement.
  • a coil 23 and a coil 24 generate a magnetic field, by means of which a magnet 25, which is connected to the rod 5, can be set in vibration.
  • the rod 5 is held by springs 26 and 27 and possibly dampened in the vibration.
  • the back and forth vibration of the rod 5 is transmitted to the throttle valve via a rocker arm 28 which is fastened to the axis 3 of the throttle valve 2.
  • the rocker arm converts the translatory movement into a rocking movement.
  • the tilting movement is limited by an end stop 29.
  • FIG. 7 shows an oscillation generator for the back and forth movement.
  • the piezo block 20 with the spring 26 causes the rod 5 to oscillate back and forth, which is thus transmitted via the rocker arm 28 as a rocking movement to the throttle valve 2, which is not shown.
  • a damping element 30 is arranged, which also serves as a guide sleeve.
  • FIG. 8 shows a vibration generator 31 for the back and forth movement.
  • the rod 5 is designed in the region of the axis 3 as a rack 32.
  • the rack 32 engages in a gear 33 which is fixed on the axis 3.
  • the back and forth movement or the tilting movement is limited by end stops 34 and 34a.
