Abstract
The invention relates to an inductive transformer for transmitting measurement data and/or electrical energy between two components (1, 2) moving relative to one another, with one primary and one secondary transformer part (4, 5), in which a gap is formed between the moving components (1, 2). A slide ring (6; 7), which comprises a plastic with embedded ferromagnetic metal parts is disposed in the gap. And that the metal parts are distributed so nonhomogeneously in the plastic that their proportion, on the end with which it is solidly disposed on one of the components (1, 2), is high and becomes relatively slight toward the end with which it rubs against the respectively other component (1, 2).
Claims5
An inductive transformer for transmitting measurement data and/or electrical energy between two components (1, 2) moving relative to one another, with one primary and one secondary transformer part (4, 5), in which a gap is formed between the moving components (1, 2), characterized in that
- a slide ring (6;
- 7), which comprises a plastic with embedded ferromagnetic metal parts is disposed in the gap;
- and that
- the metal parts are distributed so nonhomogeneously in the plastic that their proportion, on the end with which it is solidly disposed on one of the components (1, 2), is high and becomes relatively slight toward the end with which it rubs against the respectively other component (1, 2).
The inductive transformer of one of the foregoing claims, characterized in that
- one transformer part (4) is mounted on the steering spindle (2) of a vehicle, and another transformer part (5) is mounted on the steering column of a vehicle;
- and that
- via the transformer parts (4, 5), a transmission of measurement data and/or energy can be performed.
