Definitions

  • the invention relates to an inductive transformer consisting of two coils each with a core.
  • Such inductive transformers are used for the transmission of Data and / or energy between two are relative to each other used moving parts; z. B. in the form of Drehübertragern for transmitting data and / or energy in turning Parts (eg steering wheels in motor vehicles) or in the form of Linearübertragern with linearly moving parts.
  • the transformers consist of two coils, each with a core, the both cores are movable relative to each other.
  • the data and / or Energy transfer by means of induction (transformer principle).
  • an inductive transformer which consists of two coils one core each.
  • the two cores are movable relative to each other.
  • Of the Transformer is additionally equipped with an oscillating circuit, which with a the two coils is connected. With this circuit switches are controlled. This Switches are switched on or off by several magnets.
  • the oscillating Circuit is used to shut off the coil when a threshold frequency is reached.
  • a threshold frequency is reached.
  • the inventive inductive transformer with the features of Claim 1 has the advantage that the transformer very small and compact builds. Because two separate systems with different functions integrated in a single inductive transformer system are, reduces the number of items. this leads to a cost saving with the same functionality.
  • FIG. 1 shows a first embodiment of the invention shown.
  • the inductive Transformer designed as a rotary transformer. It consists of two Coils 1, 2 each having an annular core 3, 4, one of which - In the embodiment of the core 3 - rotatable about an axis Z. is stored.
  • the two cores 3, 4 can be L-shaped in cross section be educated.
  • the core 4 facing leg of the L of core 3 is with a contour 5, here a slope, Provided.
  • the slope opposite is at the core 4 a Magnetic field-sensitive sensor 6 is arranged as the Hall sensor, magnetoresistive sensor o. The like. Be formed can.
  • Figures 2 and 3 show a further embodiment, in which of the inductive transformer as a linear transformer is trained.
  • a linear transformer z. B. with removable seats in motor vehicle signals from controls and Side airbags or power for seat heating or servomotors
  • the position of the seats can be transferred automatic seat adjustment can be measured.
  • the linear transformer according to Figures 2 and 3 operates on the Same principle as the rotary transformer of Figure 1.
  • the coil 2 is with its core 3 in the direction of the arrows X in Figure 2 movable.
  • the core 4 is at its the core 3 facing side provided with a contour 5, as in the Embodiment of Figure 1 is designed as a slope.
  • the slope is at least one free leg of the U educated.
  • Core 3 at least one free leg of the U a sensor. 6 arranged. If both free legs of the U of core 4 with a contour 5 are provided, it is also possible to both free legs of the U of core 3 to attach a sensor 6.
  • the air gap 7 between the two cores 3 changes and 4. This causes a change in the magnetic flux, the can be measured by the sensor 6.
  • the measured magnetic River is in direct proportion to the position of the two Cores 3 and 4 to each other.
