Definitions

  • the invention relates to a bistable solenoid with an excitation coil and, with respect to the excitation coil by a switching current in the excitation coil in a first switching position and a second switching position, adjustable piston and a piston position detector for detecting whether the piston is moved to its first or second switching position has.
  • the piston is connected to a sealing element, which releases or interrupts the flow of a medium through a valve arranged outside the switching magnet, depending on the piston position.
  • the document EP 2 164 081 A2 discloses a switching magnet in which the piston position detector is formed by two mechanical contacts. Depending on the switching position of the piston of the solenoid either one or the other mechanical contact is closed.
  • the provision of mechanical contacts has the disadvantage of additional friction and mechanical wear of the contacts.
  • the invention has for its object to provide a solenoid with piston position detector, in which the above-mentioned disadvantages are avoided.
  • this task is solved by means of the features of claim 1, characterized in that the piston position detector is formed by at least one magnetic flux density in the magnetic circuit generating permanent magnet and arranged in the magnetic circuit magnetic field sensor, both fixed with respect to the exciter coil fixed in the Switching magnets are provided, and wherein the piston position detector has evaluation means which evaluate the magnetic flux density in the magnetic circuit, which is measured by the magnetic field sensor and is dependent on the switching position of the piston in order to detect the piston position.
  • the advantage is obtained that the detection of the current position of the piston in the switching magnet takes place without contact. Since the magnetic field sensor does not detect the magnetic field generated by the exciting coil only for switching the switching position of the piston, but the magnetic field always present through the permanent magnet, the detection of the piston position can always take place when the piston has assumed one of its two possible switching positions.
  • position detectors are known in which on the Moving part (eg locking pin or piston) is a permanent magnet is fixed and detected with a stationary magnetic field sensor, whether the permanent magnet is close (eg first switching position) or far away (eg second switching position) of the magnetic field sensor.
  • this additional permanent magnet on the moving part can be dispensed with because the magnetic field of the permanent magnet is used for position detection, which is provided for holding the piston in its second switching position.
  • costs can be saved in the production of the solenoid.
  • the piston without a permanent magnet mounted on the piston can be made lighter and more mobile, which is advantageous both in terms of the switching speed and for the current required for switching current of the switching current.
  • FIG. 1 shows a bistable solenoid 1 as part of a bistable diaphragm valve, which is designed according to this example for shutting off or releasing a water pipe of a car.
  • the water is supplied to the diaphragm valve in a volume and discharged through another volume of the diaphragm valve again.
  • the solenoid 1 has a piston 4, which in FIG. 1 is shown in its first switching position.
  • a spring 5 presses a stop ring 6 with a spring force FK in the direction R against a stop surface 7 of the housing of the solenoid 1.
  • the volume and the other volume are connected together and it is the water flow in the line of the Diaphragm valve released.
  • the piston 4 is displaceable against the spring force FK against the direction R in a second switching position.
  • a sealing element not shown in the figures seals the volume against the other volume, so that the flow of water is interrupted in the line.
  • Switching magnets according to the invention can be used for a large number of other application examples, which are not discussed in more detail in this description.
  • the solenoid 1 is formed bistable, which is why the piston 4 is positioned either held in its first switching position or in its second switching position.
  • the spring 5 holds the piston 4 with the spring force FK in its first switching position.
  • the switching magnet 1 further has a permanent magnet 8 which exerts a magnetic attraction force MK against the direction R on the piston 4 via a pole core 9.
  • the magnetic attraction force MK is too weak to move the piston 4 from its first switching position to its second switching position.
  • the spring force FK is too weak to move the piston 4 from its second switching position to its first switching position.
  • the solenoid 1 now further comprises an excitation coil 10, in which a switching current (DC) can be fed with a first polarity to move the piston 4 from its first switching position to its second switching position, and in a switching current with a second polarity can be fed to adjust the piston 4 from its second switching position to its first switching position.
  • a switching current DC
  • the shift solenoid 1 further includes a piston position detector for detecting whether the piston is adjusted to its first or second shift position. On the basis of this information from the piston position detector, for example, the vehicle electronics check the switching state of the piston 4 and initiate appropriate measures in case of deviations from the desired state.
  • the piston position detector comprises a Hall sensor 11, the permanent magnet 8 and evaluation means, which in the FIG. 1 are not shown in detail.
  • a magnetic circuit is formed, via which the magnetic flux of the permanent magnet 8 from the permanent magnet 8 via the pole core 9, the piston 4 and the air gap between the piston 4 and the pole core 9 or the housing, is passed through the housing of the switching magnet 1 to the permanent magnet 8.
  • a switching current is impressed into the excitation coil 10
  • the magnetic flux of the excitation coil superimposed on the magnetic flux of the permanent magnet 8, whereby the piston 4 is adjusted between its two switching positions.
  • the Hall sensor 11 is now mounted between the piston 4 and the housing in the region of the magnetic circuit, which is why the Hall sensor 11 measures the magnetic flux density in the magnetic circuit.
  • FIG. 2 a measurement characteristic M of the flux density measured in millitesla [mT] by the Hall sensor 11 as a function of the length in millimeters [mm] of the air gap of the piston 4 to the pole core 9 is shown.
  • the length of the air gap is about 0 mm and the Hall sensor 11 measures a magnetic flux density of about 24 mT.
  • Evaluation means of the piston position detector are now adapted to detect that the piston 4 is adjusted to its first switching position when the measured magnetic flux density is less than a lower threshold OS of 7 mT. Furthermore, the evaluation means of the piston position detector detects that the piston 4 is adjusted to its second switching position when the measured magnetic flux density is greater than an upper threshold value US of 18 mT.
  • the dependence of the magnetic flux in the magnetic circuit on the switching position of the piston 4 and the application of the upper threshold OS and lower threshold US has the advantage that the piston position detector can detect the switching position of the piston 4 without contact and without an additional permanent magnet.
  • the specified threshold values are to be understood as an example and depend on the particular design of the switching magnet and the magnetic field strength of the permanent magnet.
  • the Hall sensor 11 may be formed as a threshold value switch, which advantageously thereby already takes over the evaluation of the evaluation. As a result, it is thus possible to dispense with separate evaluation means.
  • a solenoid 12 is shown as a second embodiment of the invention.
  • the switching magnet 12 has the same structure as the switching magnet 1, wherein additionally a second permanent magnet 13 is attached as part of the piston position detector on the side of the Hall sensor 11 on the piston 4.
  • the second permanent magnet 13 can be used to influence the magnetic flux density at the magnetic field sensor. For some magnetic field sensors, a signal symmetric about the 0-point is advantageous. In this case, the second permanent magnet 13 is reversely poled as the permanent magnet. 8
  • NdFeB magnets known to those skilled in the art from other fields. These NdFeB magnets are characterized by their large magnetic field strength with relatively small volume of the permanent magnet.
  • the position of the Hall sensor 11 immediately adjacent to the displaced in its first switching position piston 4 has proved advantageous for constructive considerations.
  • Other positions of the Hall sensor 11 in the region of the magnetic circuit or the stray field of the magnetic circuit would be possible for the measurement of the magnetic flux density in the magnetic circuit.
  • a threshold value of the magnetic flux density would have to be determined which corresponds to the respective length of the air gap between the piston 4 and the pole core 9.
  • the bistable solenoid could also have a permanent magnet on each side of the piston, in which case the spring 5 would not be necessary and each of the permanent magnets would hold the piston in one of the two shift positions. Furthermore, it is also possible to use arrangements with two coils and a radial permanent magnet between the coils.
  • the solenoid could have a connectable to a data bus control electronics, the from the data bus, a switching information can be fed and which is designed to evaluate the switching information and for outputting the switching current to the excitation coil.
  • a data bus protocol the protocol according to a so-called LIN bus (Local Interconnected Network) has proven to be advantageous in automotive applications.
  • the bistable solenoid can also be provided in a switching valve, with the example, the water or oil supply is controlled.
  • the advantage is obtained that a likewise connected to the LIN bus control unit of a car via only one data line can deliver the switching information to the bistable switching valve, whereby costs can be saved and digital processing is possible.
  • the evaluation means of the Kolbepositionsdetektors a position information can be delivered to the control electronics, which at certain times (eg every three seconds) and / or on request of the control unit of the car outputs the position information via the data bus to the control unit.
  • the control unit of the car is always informed about the current position of the piston of the bistable switching valve, whereby the troubleshooting in the workshop is much easier.
  • the magnetic flux density of the permanent magnet 8 may be mitigated weakening or amplifying.
  • the polarity as attenuating has proven to be advantageous in the embodiment.
