Definitions

  • the invention relates to an inductive transformer, in particular a rotary transformer, for signal and energy transmission between moving components according to the preamble of the main claim.
  • bidirectional data transmission between the steering column and the steering wheel should be possible with simultaneous energy transmission from the steering column to the steering wheel.
  • the energy transfer can be approx. 1 W if only the steering wheel electronics need to be supplied, and an additional 120 W if a steering wheel heater is to be supplied.
  • information regarding the actuation of the horn, the control buttons for driving comfort, a telephone call button, speed control (cruise control), certain radio functions or airbag monitoring and ignition can be replaced.
  • a winding spring for data transmission and / or a slip ring for energy transmission is conventionally provided.
  • an inductive transmitter for transmitting measurement data and electrical energy between two mutually movable components with a primary and a secondary transmitter part is advantageously further developed with the means specified in claim 1.
  • a transmitter for the transmission of measurement data and a transmitter for the transmission of electrical energy.
  • the primary and the secondary transmitter parts of each transmitter are housed in separate, magnetically largely shielded chambers, which are formed by concentric and radial metal walls on the movable components, with the concentric walls each other grip that they form the radially successive chambers.
  • a metallic chamber element can be arranged on each of the mutually movable components, each of which has a double U-shape in radial section and whose concentric walls are arranged in such a way that they interlock without interfering with the rotary movement.
  • This is preferably applied in such a way that the one transmitter parts and chamber elements are attached to the steering spindle of a vehicle and the other transmitter parts and chamber elements are attached to the steering column of a vehicle.
  • the middle separator of the two chamber elements serves as a magnetic part for both parts of the transmission, but has no significant crosstalk, since in most applications, e.g. in the motor vehicle, frequencies of 50 kHz or several megahertz only a magnetic skin effect occurs and the magnetic interactions do not have a disruptive effect.
  • 1 and 2 each show a view of a rotary transmitter between a steering spindle and a steering column of a motor vehicle with separate transmitter parts for a signal and an energy transmission in separate chambers.
  • FIG. 1 shows an inductive transformer which has chamber elements 1 and 2 which intermesh like a comb and are part of a steering device for a motor vehicle, which is not shown here and is not explained in detail.
  • the chamber element 1 is attached to a steering column, for example, and the chamber element 2 is then attached to a steering spindle.
  • the end of the steering spindle can be rotated by means of a steering wheel, the steering spindle being rotatably held on the steering column, which is firmly connected to the chassis of the vehicle.
  • a primary transmitter part 3 is arranged on element 1 and a secondary transmitter part 4 on element 2 for signal transmission and a primary transmitter part 5 on element 1 and a secondary transmitter part 6 on element 2 for energy transmission. This can then be used to transmit measurement data and electrical energy between sensors arranged, for example, on the steering spindle and a central evaluation unit in the vehicle.
  • a chamber 7 for signal transmission By forming the comb-like concentric and radial walls of the chamber elements 1 and 2 here is a chamber 7 for signal transmission and a chamber 8 for energy transmission. Mixing signal and energy transmission can thus be avoided in a simple manner by the thus achieved formation of two transmitters separated by chamber walls.
