Definitions

  • the invention is based on an electromagnetic valve with at least one coil including at least one bobbin, according to the preamble of claim 1 and a method for their preparation according to claim 4.
  • electromagnetic coils are used to control by means of electromagnetic forces with valve seats cooperating valve body.
  • electromagnetic valves are used, for example, in electronically controlled brake systems (EBS) of commercial vehicles and switch or control depending on their current supply braking or control pressures.
  • EBS electronically controlled brake systems
  • valves are subjected to different operating voltages.
  • an on-board voltage of 12 volts is common, but in Europe this voltage is usually 24 volts.
  • the performance of the 12 volt and 24 volt solenoid valves should be essentially identical.
  • the coils for 12 volt solenoid valves each have a one-piece wire winding with a wire diameter of about 0.3 to 0.5 mm with a relatively high number of turns used to achieve a required electrical and / or magnetic minimum power. As a result, builds such a coil relatively large.
  • the coil for 24 volt solenoid valves uses a coil wire with a smaller wire diameter of approximately 0.2 to 0.3 mm, which makes the 24 volt coils approximately 20% smaller than the 12 volt coils. Do the washing up.
  • the respective receptacles for the different sized coils to otherwise identical identically designed solenoid valves with different dimensions, which increases the manufacturing cost unfavorably.
  • solenoid valves used in electronic regulated brake systems are usually used in so-called.
  • Pressure control modules as inlet-outlet and backup valve combination, which are installed close to the wheel or near the axis, where usually only little space is available. Therefore, there is one Need for as small as possible solenoid valves. The same applies to solenoid valves for other applications, such as solenoid valves in transmission controls.
  • the present invention is based on the object, an electromagnetic valve of the type mentioned in such a way that it can be operated in the smallest possible space without major changes with different operating voltages and still delivers substantially identical performance data such as electrical power and / or magnetic power , In addition, a method for its production must be specified.
  • the invention is based on the idea that the bobbin of the coil of the electromagnetic valve is provided with at least two separate wire windings, two of which are connected in series or parallel to each other. This includes, for example, only two wire windings connected in series or in parallel. In addition, a variety of combinations are conceivable, for example, four wire windings, of which the first and the second wire winding parallel, the second and third wire winding in
  • the number and the winding parameters of the wire windings are chosen such that, depending on the wiring of their wire windings, the wind applied to predetermined different operating voltages supplies substantially identical electrical and magnetic characteristics, such as electrical power and / or magnetic power.
  • a thinner wire than the prior art may be used, in particular with a wire diameter which corresponds to that of the wire winding of a coil of a 24 volt solenoid valve.
  • the remaining components of a 12 volt solenoid valve and the 24 volt solenoid valve as possible not differ from each other and the switching characteristics should be identical in both cases as possible, are approximately identical electrical variables such as the electrical power and magnetic power of the coils in the 12 volt solenoid valve and in the 24 volt solenoid valve desirable.
  • magnet valve types for different operating voltages can be implemented by inserting an otherwise standardized coil into a likewise standardized solenoid valve, merely by correspondingly connecting the two wire windings to the respectively required operating voltage. This saves expensive production and storage of different coils and solenoid valves.
  • the reference numeral 1 shows a coil of an electromagnetic valve, not shown otherwise, as used for example in a pressure control module of an electronically controlled braking device (EBS) of a commercial vehicle.
  • the coil is for example provided for a 12 volt solenoid valve, ie its operating voltage is 12 volts, because the electrical system of the commercial vehicle is designed for this voltage.
  • the coil includes, for example, two, preferably in terms of winding parameters such as number of turns, wire diameter, wire cross-section (round, square) and wire material identical but separate wire windings 2, 4 of conventional copper wire, which are wound on a preferably one-piece, not shown here bobbin.
  • the bobbin could also be multi-part, or each wire winding 2, 4 is associated with its own bobbin.
  • the ends 6 of the wire windings 2, 4 are led out of these so that the two wire windings 2, 4 can be connected either in series or in parallel to each other.
  • the diameter of the coil wire is, for example, 0.2 mm to 0.3 mm.
  • the two wire windings 2, 4 parallel to each other interconnected for example, characterized in that the led out of the wire windings 2, 4 ends 6 are connected to each other on a circuit board accordingly.
  • the coil 1 under different operating voltages, here for example 12 volts and 24 volts, in parallel connection and in series of their two wire windings 2, 4 substantially identical electrical parameters such as electrical power and / or magnetic power and thus forms a standardized unit Used in solenoid valves with 12 Volt and 24 Volt operating voltage.
  • the coil recordings of a 12 volt solenoid valve or a 24 volt solenoid valve, which are usually each formed by a coil bore in the valve housing have identical dimensions.
  • such a 12 volt or 24 volt solenoid valve in turn forms a standardized unit, as apart from the interconnection of the wire windings 2, 4 of the coil 1, the remaining components of the 12-volt solenoid valve and the 24-volt solenoid valve not from each other differ.
  • the invention is not limited to the embodiment with two separate wire windings 2, 4 on the bobbin. Rather, more than two separate wire windings may be provided depending on the respective predetermined operating voltages, which may also have different winding parameters such as number of turns, wire diameter, etc. The number and interconnection of the individual wire windings and their winding parameters are adjusted by the skilled person depending on the required electrical and magnetic performance and in particular of the specified operating voltages on a case by case basis.
  • the wire windings are wound on the bobbin 10 one above the other, as seen from Figure 3 evident.
  • a first wire winding 2 is wound on the one coil core 8 enclosing bobbin 10 as the innermost layer, a first wire winding 2.
  • This first wire winding 2 is in turn wrapped by a second wire winding 4 and the latter in turn by a third wire winding 12th
