Definitions
- Inductive transformer consisting of two coils with one core each
- the invention relates to an inductive transformer consisting of two coils, each with a core.
- Such inductive transmitters are used for the transmission of data and / or energy between two parts moving relative to one another; z. B. in the form of rotary transmitters for the transmission of data and / or energy in rotating parts (z. B. steering wheels in motor vehicles) or in the form of linear transmitters with parts moving linearly to each other.
- the transformers consist of two coils, each with a core, the two cores being movable relative to one another.
- the data and / or energy transmission takes place by means of induction (transformer principle).
- the inductive transformer according to the invention with the features of claim 1 has the advantage that the transformer is very small and compact. Since two separate systems with different functions are integrated in a single system, the number of individual parts is reduced. This leads to cost savings with the same functionality.
- FIG. 1 shows a section through an inductive transformer in the form of a rotary transformer
- Figure 2 shows an inductive transformer in the form of a linear transformer
- the inductive transformer is designed as a rotary transformer. It consists of two coils 1, 2, each with an annular core 3, 4, one of which - in the exemplary embodiment, the core 3 - is rotatably supported about an axis Z.
- the two cores 3, 4 can have an L-shaped cross section.
- the leg of the L of the core 3 facing the core 4 is provided with a contour 5, here a bevel.
- a magnetic field-sensitive sensor 6 is arranged on the core 4, which acts as a Hall sensor, magnetoresistive sensor or the like. can be trained.
- FIGS. 2 and 3 show a further embodiment in which the inductive transformer is designed as a linear transformer.
- the inductive transformer is designed as a linear transformer.
- z. B in removable seats in motor vehicle signals from controls and side airbags or energy for seat heating or actuators transmitted and in addition the position of the seats can be measured with automatic seat adjustment.
- the linear transformer according to FIGS. 2 and 3 works on the same principle as the rotary transformer according to FIG. 1.
- Two coils 1, 2, each with a core 3, 4, are also provided, the two cores 3, 4 being U-shaped in cross section could be. However, they can also be L-shaped.
- the core 2 of the coil 2 can be moved in the direction of the arrows X in FIG. 2.
- the core 4 is provided on its side facing the core 3 with a contour 5 which, as in the exemplary embodiment according to FIG. 1, is designed as a bevel.
- the bevel is formed on at least one free leg of the U.
- a sensor 6 is arranged on the core 3 on at least one free leg of the U on the side opposite the slope. If both free legs of the U of core 4 are provided with a contour 5, it is also possible to attach a sensor 6 to both free legs of the U of core 3.
- the air gap 7 between the two cores 3 and 4 changes. This results in a change in the magnetic flux, which can be measured by the sensor 6.
- the measured magnetic flux is directly related to the position of the two cores 3 and 4.
- only the coil 1 in the core 4 has current flowing through it, while the coil 2 in the core 3 has no current flowing through it and is only used for induction with the coil 1 in the core 3.
