Definitions

  • the invention relates to a direct drive for a throttle shaft in a throttle body.
  • Direct drives are known for example from US 5,738,072. As a rule, this involves the arrangement of a coil, which is acted upon by electric current and a rotor arranged in its area of action, which is provided with permanent magnets and is set into a rotary motion by the coil induction.
  • the invention has for its object to provide a direct drive for a throttle shaft in a throttle body, with which a position detection of the throttle is continuously possible and requires only a relatively small space.
  • a direct drive for a throttle shaft in a throttle body which consists of a coil and a rotor arranged directly adjacent to the coil, in which the rotor consists of a steel ring, in which a first inner inner magnetic shell and a second inner magnetic shell lie opposite each other and abut on its outer side a first outer magnetic shell and a second outer magnetic shell opposite each other and in which the steel ring is connected at its end facing the throttle valve with the throttle shaft, and in which in the region facing away from the throttle end of the Steel ring centered a sensor for position detection of Throttle valve is arranged.
  • the rotor is located directly next to the coil.
  • the first outer magnetic shell and the second outer magnetic shell serve to drive the rotor via the coil. It has surprisingly been found that with the direct drive for a throttle shaft in a throttle body position detection of the position of the throttle in the throttle body is possible in a relatively simple manner, with only relatively little space is required because the arrangement of the sensor over a portion of the Coil is realized.
  • the arrangement of the steel ring has the advantage that the magnetic fields, due to the first inner magnetic shell and the second inner magnetic shell on the one hand and the first outer magnetic shell and the second outer magnetic shell on the other hand not adversely affect each other, so that the sensor with accurate information about the actual position of the throttle in the throttle body is supplied, which can then be passed on to the control units.
  • a preferred embodiment of the invention is that the first inner magnetic shell and the first outer magnetic shell and the second inner magnetic shell and the second outer magnetic shell are each arranged parallel to each other on the same half of the steel ring. This advantageously facilitates the manufacture of the rotor of the direct drive for a throttle shaft.
  • the first inner magnetic shell and the first outer magnetic shell and the second inner magnetic shell and the second outer magnetic shell each have the same magnetic polarity. In this way, the course of the magnetic lines in the area of the steel ring can be optimized, whereby the quality of the information supplied to the sensor can also be optimized.
  • a further preferred embodiment of the invention is that the steel ring in the region facing away from the throttle end has an annular groove in which the first inner magnetic shell and the second inner magnetic shell abut the steel ring.
  • the first inner magnetic shell and the second inner magnetic shell can be securely fixed in a relatively simple manner in the steel ring, while preventing the first inner magnetic shell and the second inner magnetic shell over the entire width of the steel ring extend. It is advantageous that the first inner magnetic shell and the second inner magnetic shell are only in the region of the sensor and thus even the smallest disturbing influences on the actual drive can be avoided.
  • a further embodiment of the invention is that the first inner magnetic shell or the second inner magnetic shell at a distance a of 1 mm to 3 mm are arranged to the annular groove defining stop of the steel ring. In this way, the shielding effect of the steel ring can be optimized, which has an advantageous effect on the position detection of the throttle valve.
  • the first inner magnetic shell and the second inner magnetic shell or the first outer magnetic shell and the second outer magnetic shell are each arranged as a single part.
  • the item thus acts as a ring magnet. This facilitates the production of the direct drive for a throttle shaft, since the number of items that must be fixed in the region of the rotor is reduced.
