Definitions

  • the invention relates to a device for transmitting a torque, in particular for a hydrodynamic machine, with a measuring system having the features of the preamble of claim 1.
  • Hydrodynamic systems in particular in the form of hydrodynamic brake devices, also called retarders, are known in a large number of designs from the prior art.
  • these comprise a first blade wheel acting as a rotor, which is rotatably connected or connectable to a shaft to be braked, and a stator, which is fastened to a stationary component, in particular a housing, and is supported on it.
  • the rotor and the stator form a working space that can be filled with operating fluid, wherein the operating medium generates a braking torque when it is circulated through the rotor on the stator.
  • the brake torque that can be generated depends on many parameters. Thus, manufacturing tolerances have an influence on the function of the retarder. These cause, for example, that there are deviations between the desired and actually acting braking torque. A theoretically achievable braking torque could thus remain unused or there are undesirably large deviations in the other direction, for example, reaction deviations may occur.
  • measuring systems which measure the braking torque acting, as disclosed, for example, in DE10 2005 052 105.
  • a system is proposed in which a device for detecting the supporting torque between the stator and the housing is used.

  • two shaft sections are provided on the shaft, which consist of a ferromagnetic material and which correspond with a respective magnetic field sensor. The angle change, with torsion of the shaft, is a measure of the applied torque.
  • the physical measuring principle of magnetostriction has been known for a long time, in which a steel shaft in the measuring region, a shaft section region, is magnetized in such a way that a permanent magnetic field of suitable structure results. Under torsion, the magnetic flux density changes in the vicinity of the shaft and as a result, the inductance of the adjacent housing-fixed coil. With a suitable electrical circuit, the inductance change can be converted into a torque-proportional measurement signal. This measurement is made without contact.
  • a disadvantage of this type of measurement is that the measurement signal depends strongly on the radial distance between the coil and the shaft or magnetic shaft section range. If the distance changes, measuring errors occur at the measuring points. Therefore, at least two measuring points are required offset by 180 °, so that by averaging the signals of the error can be eliminated.
  • the shaft is surrounded at the measuring points by a respective ring, which holds the measuring coils in position. Replacing this ring is only possible with very large assembly costs. Since the price and the lifetime of the sensors are very small in relation to the entire machine, this assembly unfriendliness is a major obstacle.
  • One of the objects of the invention is to obviate the drawbacks and to provide a device in which the measuring system for detecting a variable characterizing the torque is improved.
  • Claim 1 describes the solution according to the invention of the task. Further advantageous embodiments and preferred variants of the solution are described in the subclaims dependent thereon.

  • Figure 1 shows an example of a device with shaft 5 and measuring system.
  • the measuring system includes an electronic circuit 14 with a voltage input for power supply and an output for the measurement signal.
  • This electronic circuit feeds the coil with a high-frequency oscillation signal in the kHz range.
  • the magnetic flux density is determined metrologically from the required time to inductive saturation of the respective coil. This result is finally processed into a stable standardized measurement signal.
