Definitions

  • the invention relates to a lifting magnet according to the features of the preamble of claim 1.
  • Such a solenoid is from the DE 196 22 794 A1 known.

  • a pole core and a magnetic piston displaceable along a center axis of the bobbin in the direction of the pole core to a Hubendposition are arranged, wherein the housing has a through hole for the magnetic piston on its side opposite the pole core.
  • Electromagnetic solenoids (often referred to as electromagnetic actuators) are used in many areas to perform setting or switching functions. The limiting of the stroke movement is typically carried out by a mechanical stop in the Hubendposition. The approach of this end position is also associated with mechanically damped versions with a noise, which is very often perceived by the user as disturbing. Technically possible control of the lifting operation, for example by way detection and current control are not used for cost reasons in standard applications.

  • An annular plain bearing bush 6 is seated in the through hole 1e of the transverse leg 1c of the iron yoke element 1 and extends into the through hole 4a of the bobbin 4.
  • This annular plain bearing bush 6 is provided on its inner circumferential surface with a sliding layer, for example a PTFE layer.

  • the present invention has for its object to improve the known lifting magnet to the effect that an increase in the tightening force in Hubend Scheme the magnetic piston is avoided and thus to reduce the noise when switching the solenoid considerably. Furthermore, the invention has for its object to provide a solenoid, which has an improved controllability of the displacement of the magnetic piston.
  • the inventively generated parasitic air gap leads to an increased magnetic resistance in the magnetic circuit, which reduces the lifting force when the magnetic piston approaches its Hubendposition and thereby the speed of the Reduce the impact of the magnetic piston on the pole core or prevent the impact at all.
  • This innovation allows virtually silent switching of the solenoid.
  • an additional parameter influencing the working air gap force characteristic is introduced by the innovation according to the invention, with which the working air gap force characteristic, in particular in the stroke end region, can additionally be influenced and optimized for the respective application purpose.

  • a spring biases the magnetic piston against the force exerted by the exciter coil magnetic force, wherein the spring force of the spring is designed so that the magnetic piston is spaced in its Hubendposition of the pole core.
  • the magnetic piston has a reduced piston diameter in the control section, whereby a parasitic air gap in the passage opening of the piston-side region of the iron yoke element adjusts in the course of the displacement of the magnetic piston in the direction of Hubendposition upon entry of the control section into the passage opening, since the Increased distance between the wall of the through hole and the generatrix of the magnetic piston.
  • the diameter of the magnetic piston in the control section can be reduced in one or more stages, whereby the parasitic air gap gradually increases as the magnetic piston approaches the stroke end position.
  • the diameter of the magnetic piston in the control section in a direction opposite to the pole core direction are at least partially steadily reduced, whereby a more uniform course of the working air gap force characteristic is achieved because the parasitic air gap changes continuously.
  • the control portion of the magnetic piston may be conical or the generatrix of the control portion of the magnetic piston at least partially have a curved course in order to achieve a particularly uniform course of the working air gap force characteristic.
  • the control section of the magnetic piston is realized by a shortened compared to conventional magnetic piston length of the magnetic piston by the length of the magnetic piston is chosen so short that in Hubendposition the magnetic piston of the control portion of the magnetic piston or only partially protrudes into the passage opening at the piston-side region of the iron yoke element.
  • the parasitic air gap in this case extends over the entire cross-sectional area of the through-hole and the magnetic flux of force concentrates on the part of the control section of the magnetic piston which projects into the through-hole. As this part becomes smaller and smaller with the movement of the magnetic piston into the stroke end position, the magnetic resistance increases and hence the lifting force decreases.
  • FIGS. 2 to 6 These embodiments represent modifications of the lifting magnet shown in Fig. 1 and described in detail above, wherein for components used in both the known and in the lifting magnet according to the invention, the same reference numerals are used in the drawings and referred to their function on the above description becomes.
  • the illustrated in Fig. 2 first embodiment of a lifting magnet according to the invention comprises a magnetic iron yoke element 1 in the form of a U-shaped bracket, which is bent, for example, of sheet metal.

  • the bobbin 4 has an axial passage opening 4a in which a pole core 2 is arranged at one end.
  • an annular plain bearing bush 6 and a magnetic piston 15 mounted therein displaceably made of a soft magnetic material.
  • the magnetic piston 15 When the exciting coil 3 is supplied with electric current, the magnetic piston 15 is attracted by the electromagnetic force of the exciting coil 3 and displaced along a center axis M in the axial through hole 4a of the bobbin 4 in the direction of the pole core 2 to a stroke end position HE.
  • the iron yoke element 1 has at the pole core 2 opposite piston-side region, ie the transverse leg 1c, a through hole 1 e, which is dimensioned so that the magnetic piston 15 can pass.
  • the construction of the solenoid is conventional.

  • the control section 15a is characterized by a decreasing diameter, this diameter - starting from the diameter D1 of the central portion of the (cylindrical) magnetic piston 15 to the end remote from the pole core 2 end of the control section to a diameter D2, wherein the transition from the larger diameter D1 to the smaller diameter D2 is continuous, wherein the generatrix of the control section 15a presents as a quarter circle.
  • the control portion 15a of the magnetic piston 15 enters the through hole 1e from the outside. Due to the continuously decreasing diameter of the control section 15a, a parasitic air gap 16 is caused in the passage opening 1e, which reduces the magnetic flux from the transverse leg 1c of the iron yoke element 1 and thereby also reduces the lifting force.
  • the magnetic flux is lowest when the magnetic piston 15 has reached the stroke end position, as shown in the working air gap force diagram of FIG. It can be seen from the characteristic curve B that at the beginning of the stroke, if the working air gap 8 has a length of 6 mm, the lifting force amounts to slightly more than 2 N. As the working air gap decreases, the lifting force increases to a.
  • the control section 15 enters the through hole 1 e and thereby generates the parasitic air gap 16 (or increased due to manufacturing tolerances and the presence of plain bearing bush 6 existing parasitic air gap).
  • the parasitic air gap 16 leads to a decrease in the lifting force to about 3 N at the Hubendposition HE.
  • the reduced lifting force at the end of the stroke allows for almost silent switching operations of the solenoid.
  • a further measure is provided which allows virtually noiseless switching operations.
  • This measure includes the interpretation of the spring force of a known spring 19 (see spring 9 in Fig. 1), which serves as a return element for the magnetic piston 15, such that the Hubendposition HE not by a mechanical stop of the magnetic piston 15 on the pole core 2, but by an equilibrium of forces exerted by the spring 19 on the magnetic piston 15 Spring force with the electromagnetic forces generated by the exciting coil 3, is determined.
  • the magnetic piston 15 is at its stroke end position HE spaced from the pole core 2 by about 0.5 mm, or in other words remains a residual working air gap of zero , 5 mm in length.

  • the parasitic air gap generated thereby is designated by the reference numeral 26.

  • a fifth embodiment of a lifting magnet according to the invention is shown in longitudinal section.
  • This embodiment differs from the previous embodiments in that the control portion 55a of the magnetic piston 55 has no shape deviating from the cylinder shape, but is designed as an end portion of the magnetic piston having an unchanged diameter D1.
  • the length L of the magnetic piston 55 is selected so that the control portion 55a does not project into the through hole 1 e of the iron yoke element 1, but flush with the inner surface of the transverse leg 1 c.

Since this part becomes smaller and smaller in accordance with the travel length of the magnetic piston in the stroke end position HE, the magnetic resistance increases and hence the lift force sharply drops, as shown in the curve C in the working air gap force diagram of FIG ,
