Definitions

  • the invention relates to a drive arrangement with a permanent magnet which is movably arranged between two magnet poles which are electrically excitable by means of an excitation coil and are located opposite one another and are connected by a yoke which is coupled to a part to be driven.
  • Such a drive arrangement is known from DE-OS 29 06 335.
  • a permanent magnet consisting of two oppositely magnetized halves is provided, which is movably arranged transversely to the two magnetic poles. If the magnetic poles are excited via the excitation coil, then half of the permanent magnet is drawn between the two magnetic poles, the direction of magnetization of which corresponds to the direction of magnetization of the two magnetic poles. The permanent magnet remains in this position as long as the corresponding magnetization of the magnetic poles is maintained. If the magnetic poles are magnetized in the other direction, the permanent magnet with its other half is drawn between the magnetic poles and remains in this position as long as the magnetization of the magnetic poles is maintained. In order to keep the permanent magnet in the end positions, the two magnetic poles must remain constantly excited. If the excitation is switched off, the permanent magnet assumes a central position in which the two halves of the permanent magnet are in equal parts under the two magnetic poles.
  • a permanent magnet that is only magnetized in one direction is suspended between the two electrically excitable magnetic poles so that it can vibrate by means of a spring.
  • the magnetic poles must remain permanently excited, at least for holding the permanent magnet in its one end position.
  • the invention has for its object to provide a drive arrangement of the type mentioned so that the permanent magnet and thus a coupled, driven element remains in the position reached by excitation of the magnetic poles, without the excitation being maintained after reaching this position got to.
  • the permanent magnet is arranged to be movable from one to the other magnetic pole, between these two magnetic poles there being at least a distance corresponding to the thickness of the permanent magnet plus the length of the adjustment path that laterally outside the clear space between the two magnetic poles
  • a third magnetic pole is arranged in the center of the two magnetic poles and is connected to the conclusion that the two opposite magnetic poles can also be excited by the excitation coil of the same name and the third magnetic pole of the same name can be excited with respect to these two magnetic poles, so that the thickness of the permanent magnet continues is greater than the sum of half the distance between the two magnetic poles and half the width of the third magnetic pole in the direction of adjustment of the permanent magnet, and an air gap between the permanent magnet and the third magnetic pole consists.
  • Such a construction of the drive arrangement results in two defined end positions of the permanent magnet, in which the permanent magnet is held solely by its magnetism, without the magnetic poles having to be electrically excited.
  • the magnetic flux of the permanent magnet closes via the third magnetic pole, the yoke and the magnetic pole against which the permanent magnet rests at the respective end position. Due to the force of the magnetic flux, the permanent magnet is thus held securely in the end position reached in each case.
  • the magnetization of the magnetic poles corresponding to the adjustment of the permanent magnet is achieved in that the excitation coil consists of two identical coil halves which are arranged on both sides of the connection point of the third magnetic pole in the magnetic circuit and are excited in opposite directions.
  • the magnetic holding force acting on the permanent magnet in the end positions can be increased in that plates made of ferromagnetic material are arranged on the two sides of the permanent magnet facing the opposite magnetic poles and the total thickness of the plates and the permanent magnet is greater than the sum of half the distance between the magnetic poles and is half the width of the third magnetic pole in the direction of adjustment of the permanent magnet. Due to the plates placed on the permanent magnets, the magnetic flux is increasingly guided to the third magnetic pole and the holding force is increased in this way. In addition, the plates for the magnet act as protection against destruction in the event of a switchover impact.
  • the permanent magnet can get stuck in a central position in front of the third magnetic pole. Such sticking can be avoided with certainty in that the thickness of the permanent magnet is greater than the width of the third magnetic pole lying in the direction of adjustment of the permanent magnet. As a result of this dimensioning of the permanent magnet thickness, the permanent magnet is safely pulled into one of the two end positions even with faulty pulses.
  • a tight fit of the permanent magnet on the magnetic pole in question is ensured in that the thickness of a plate is at most equal to the width lying in the direction of adjustment of the permanent magnet.
  • a sufficient tightening force is achieved in that the total thickness of the plates and the permanent magnet is greater than half the distance between the magnetic poles plus half the width of the third magnetic pole in the direction of adjustment of the permanent magnet, the overhang being Plates and the permanent magnet over the outer edge of the third magnetic pole is at most 75% of the thickness of a plate.
  • a constructive embodiment of the drive arrangement is characterized in that the two magnetic poles and the yoke connecting them have the shape of a C, the third magnetic pole being arranged with its free end pointing towards the opening and the permanent magnet at one end of a spring tongue fixedly clamped with its other end or pivotably mounted.
  • the spring tongue provided for the movable mounting of the permanent magnet is used in that control elements are arranged on it, which cooperate with corresponding counter-elements of a device to be controlled at the same time for coupling the part to be driven by the permanent magnet.
  • the drive arrangement can advantageously be used to control heating or ventilation flaps in automobiles if the counter-elements are nozzle openings connected to a vacuum control device, to which seals arranged on the spring tongue are assigned as control elements.
  • the lossless switching end positions of the magnet arrangement are advantageous here.
  • a direct coupling of the control element or elements with the adjustable permanent magnet is made possible in that the magnetic poles are designed as hollow tubes and lie concentrically in openings in the axially spaced-apart coil halves, between which a ring is inserted as the third magnetic pole, the outer edge of which is attached to one surrounding the coil halves, there is a cylindrical yoke jacket, on which cover plates carrying the hollow tubes are attached on both end faces and that a plunger of amagnetic material penetrating the hollow tube is provided on at least one side of the permanent magnet.
  • the plunger connected to the permanent magnet can serve directly as a control element if the free end of the plunger is conical and, in the direction of adjustment of the plunger, a control opening provided with a corresponding conical counter-seat and carrying a fluid is arranged in front of this free end.
  • a compact design of the drive arrangement results from the fact that a plastic part provided with a longitudinal bore receiving the plunger with a pipe socket formed thereon is inserted into one of the hollow tubes forming the magnetic poles and at the end of the longitudinal bore the control opening is formed with the conical counter-seat, which is formed by a cavity formed between the plunger and the wall of the longitudinal bore is connected to a further control opening provided on the plastic part.
  • the magnetic poles 1 and 2 denote two opposite magnetic poles which are connected to one another via a yoke 3.
  • the magnetic poles 1 and 2 form, together with the yoke in the form of a C.
  • a third magnetic pole 4 connected to the yoke is provided in the middle of the yoke 3. With its free end 5, the third magnetic pole 4 projects toward the opening existing between the two magnetic poles 1 and 2.
  • An excitation coil consisting of two identical coil halves 6 and 7 is provided to excite the magnetic poles 1, 2 and 4.
  • a coil half 6 is arranged on one side and a coil half 7 on the other side of the junction of the third magnetic pole 4 with the yoke 3 in the return circuit of the two magnetic poles 1 and 2.
  • the two coil halves 6 and 7 are simultaneously applied to voltage and are switched or wound so that they excite the yoke 3 in opposite directions.
  • the two opposite magnetic poles 1 and 2 are always of the same name and the third magnetic pole 4 is magnetized unevenly with respect to these two magnetic poles 1 and 2.
  • An airtight housing 8 made of non-magnetic material is clamped to the two opposite magnetic poles 1 and 2.
  • a spring tongue 9 is arranged in the housing 8.
  • a permanent magnet 10 is fastened, which is guided to be movable by the spring tongue 9 in the direction of the two magnetic poles 1 and 2.
  • the spring tongue 9 With its other end 9b, the spring tongue 9 is firmly clamped in the housing 8 or held rotatably between the poles.
  • the two sides of the permanent magnet 10 lying in the adjustment direction are covered flush with plates 11 and 12 made of ferromagnetic material.
  • the arrangement of the permanent magnet 10 covered with the plates 11 and 12 on the spring tongue 9 is such that an air gap 13 exists between the side of the permanent magnet 10 facing the third magnetic pole 4 and the third magnetic pole 4.
  • This air gap can be filled by the material of the housing 8.
  • a holding force which presses it against the magnetic pole 2 is exerted on the permanent magnet 10.
  • the package consisting of the plates 11 and 12 and the permanent magnet 10 projects somewhat beyond the upper edge of the third magnetic pole 4.
  • a part of the magnetic flux passes through this projection of the plate 11 over the edge of the third magnetic pole 4 obliquely down into the third magnetic pole 4. This results in a vertically downward force component, which contributes to an increase in the holding force.
  • the plate 12 projects beyond the lower edge of the third magnetic pole 4, so that an upwardly directed force component is thereby created.
  • the two coil halves are excited so that, with the polarity of the permanent magnet 10 assumed, the two opposite magnetic poles 1 and 2 are magnetized as south poles and the third magnetic pole 4 as north poles.
  • the south pole of the permanent magnet 10 is repelled by the magnetic pole 2 magnetized as the south pole and the north pole of the permanent magnet 10 is repelled by the third magnetic pole 4 magnetized as the north pole.
  • the north pole of the permanent magnet 10 is attracted by the magnetic pole 1 magnetized as the south pole. Through these forces directed towards the magnetic pole 1, the permanent magnet 10 is moved towards the magnetic pole 1.
  • the protrusion of the plate 11 over the edge of the third magnetic pole 4 has an effect, since this generates a force component directed vertically, as already described for the holding state.
  • this force component is directed upward and thus supports the start-up of the permanent magnet 10.
  • the excitation of the two coil halves 6 and 7 can be switched off again.
  • the permanent magnet 10 holds itself in this end position.
  • the permanent magnet 10 is switched back to the previous end position.
  • the seal 21 arranged on the spring tongue 9 is lifted from the mouth of one nozzle opening 20 and pressed against the mouth of the other nozzle opening 19.
  • a medium flowing through the nozzle openings can be controlled.
  • a liquid can be supplied via the nozzle opening 18, which can then flow out via the nozzle opening 19 or 20 by correspondingly switching off the permanent magnet 10.
  • a vacuum accumulator to the nozzle opening 20 and an adjusting device which can be controlled by negative pressure to the nozzle opening 18.
  • the nozzle opening 19 serves as ventilation openings.
  • the nozzle In the position shown is first the nozzle connected to the vacuum accumulator opening 20 closed.
  • the two nozzle openings 18 and 19 are connected in terms of pressure via the housing cavity 17.
  • the seal 21 lies against the mouth of the nozzle opening 19 and releases the mouth of the nozzle opening 20.
  • the negative pressure prevailing in the vacuum accumulator thus becomes effective at the nozzle opening 18.
  • the adjusting device connected to the nozzle opening 18 can be actuated by this negative pressure. If the permanent magnet 10 is switched back again, the seal 21 closes the nozzle opening 20 again and the nozzle opening 18 is again connected in terms of pressure to the nozzle opening 19, so that the ambient pressure on the adjusting device becomes effective again.
  • the opposite magnetic poles 22 and 23 are designed as hollow tubes and lie concentrically in corresponding coil openings of the two coil halves 24 and 25 arranged at an axial distance. Between the two coil halves 24 and 25 there is a ring 26 made of ferromagnetic as the third magnetic pole Material inserted. This ring 26 lies with its outer circumference on a cylindrical yoke 27.
  • the yoke circuit is completed by cover plates 28 and 29 arranged on the end faces of the yoke jacket 27 and supporting the hollow tubes 22 and 23.
  • a permanent magnet 32 covered with ferromagnetic plates 30 and 31 is arranged axially displaceably between the two hollow tubes 22 and 23.
  • a plunger 33 which extends through a hollow tube 23 and whose free end 33a is conical, is connected to the permanent magnet 32.
  • the plunger 33 protrudes into a longitudinal bore 35 provided on a plastic part 34.
  • the plastic part 34 is fastened in a clamped manner in the bore of the hollow tube 23 by means of a pipe socket 34a formed thereon.
  • a control opening 36 provided with a conical counter-seat adapted to the cone of the tappet 33.
  • a further control opening 37 opens into the cavity formed between the tappet 33 and the wall of the longitudinal bore 35.
  • An amagnetic sealing tube 38 is placed on the outside of the two hollow tubes 22 and 23.
  • the permanent magnet 32 has a slight play compared to this sealing tube 38, so that it is not braked by friction during the adjustment.
  • the hollow tube 22 opposite the hollow tube 23 connected to the plastic part 34 is provided with a closure at its outer end. In this closure there is a small bore 39 which can be closed by a further plunger 40 arranged on the opposite side of the permanent magnet 32 or a sealing ring 41 is attached to the end face of the hollow tube, through which the cavity of the hollow tube 22 comes into contact when the permanent magnet 32 is in contact this hollow tube 22 is sealed off from the cavity of the other hollow tube 23 and the longitudinal bore 35.
  • the permanent magnet 32 is moved from one end position to the other by appropriate excitation of the two coil halves 24 and 25.
  • the plunger 33 is lifted from the control opening 36 provided at the end of the longitudinal bore 35. There is therefore a pressure connection between this control opening 36 and the further control opening 37.
  • the control opening 36 is connected to a negative pressure accumulator or generator, the negative pressure becomes effective at the further control opening 37 and can be used to actuate an adjustment device connected to this control opening.
  • the plunger 35 closes the control opening 36 in the manner of a needle valve and the connection to the vacuum source is interrupted. In this position, the further plunger 40 is lifted from the bore 39. There is a connection to the bore 39 via the longitudinal bore 35, the hollow tube 23 and the play between the permanent magnet 32 and the sealing tube 38, so that the ambient pressure at the further control opening 37 and the adjustment device connected to it becomes effective.
  • the drive arrangement according to the invention only requires a short energy pulse to adjust the permanent magnet 10 or 32. Thereafter, the permanent magnet 10 or 32 holds itself in the respective end position due to its magnetism.
  • the use of the drive arrangement is therefore particularly suitable where energy is only available to a limited extent, for example in a car. At When used in a car, the drive arrangement maintains its respective tax position even when the car is at a standstill.
