Definitions

  • the invention relates to a speed sensor, in particular a gearwheel sensor, with a magnet and two Hall elements. can be moved past the speed sensor.
  • Such speed sensors are used wherever the speed or a rotational movement of a component is to be detected.
  • a preferred area of application is, for example, the automotive industry and in particular the automatic one
  • ABS Brake system
  • ASR automatic slip control
  • the known speed sensors emit an output signal when switched on, that is to say when current is supplied to them, which can be detected by the electronic control.
  • a gearwheel sensor it cannot be concluded from the presence of the output signal of this speed sensor whether a tooth or a tooth gap is assigned to the Hall IC.
  • Countable pulses only occur when the ferro-magnetic component is rotated and a complete signal period has arisen, i.e. a complete tooth and an entire tooth gap must have passed the Hall IC. So this sensor can only detect transitions.
  • the invention proposes that the speed sensor, in particular gear sensor according to the preamble of claim 1 corresponding to the characterizing Part of this claim is formed.
  • This speed sensor emits a defined switch-on signal when it is switched on and the gearwheel or similar component is stationary, i.e. there is in any case a defined switch-on state that can be appropriately detected and processed by the electronic control.
  • the pulses are counted in the same way as with the known speed sensor, i.e. For example, when a tooth reaches the Hall IC, a positive pulse is generated, while this pulse is absent when the tooth gap arrives at the Hall IC.
  • Another advantage of this speed sensor is that you can get by with a weaker magnet, which is correspondingly cheaper, which also allows the manufacturing costs of this speed sensor to be reduced.
  • the Hall element detects the height of the magnetic field in its area.
  • the basic field is the same for both Hall sensors.
  • the gearwheel or the like is closer to one Hall element than the other, the increase in the magnetic field is greater when the component is present on the Hall element near the component than on the component remote from the component.
  • a tooth follows a tooth gap, which brings about a further increase in the magnetic field. If the difference is now formed in a differential amplifier from the total amount of the magnetic field on the near-component and on the far-away Hall element, this results in a value different from zero. This enables an immediate conclusion to be drawn about the presence of a tooth or a tooth gap, because it is a defined signal which is also emitted when the gear is stationary.
  • both Hall elements are equally close to the tooth, and therefore the difference in the entire magnetic field at the differential amplifier gives the value zero there.
  • sensor 1 is assigned to a gearwheel 2 in the radial direction, ie it is aligned with a radius 3 of the gearwheel in the radial direction. According to the diagram, this refers to the magnet 4.
  • the tooth 5 is assigned the north pole of the magnet, for example, while the south pole points in the opposite direction.
  • a first Hall element 6 is located between the tooth 5 and the north pole of the magnet, while the magnet 4 is arranged between this first Hall element and a second Hall element 7.
  • this Hall IC 8 naturally also has conventional electronics, in particular a protective circuit. There is no difference to that the known speed sensors.
  • the second Hall element is farther away from the tooth 5 than the first Hall element 6. This means that the tooth 5 and also the gearwheel 2 itself cause a higher magnetic field on the first Hall element 6 than on second Hall element 2. If the signals from these two Hall elements are fed into a differential amplifier of a known type, this results in a non-zero value at the output of the differential amplifier, which leads to the unambiguous identification of the tooth and the tooth gap, ie, already after the definite signal is available for switching on, even if the gear is still stationary.
  • the front side of the first Hall element is assigned to the north pole and the rear side of the second Hall element is assigned to the south pole.
  • the second Hall element is attached to the first in a position turned through 180 °.

Abstract

Afin d'obtenir un capteur de la vitesse de rotation, notamment de la vitesse de rotation d'une roue dentée, qui émette dès sa mise sous tension un signal défini qui permette de déterminer sans aucun doute si le capteur, dans le cas d'un capteur de la vitesse de rotation d'une roue dentée, est associé à une dent ou à un entredent, on associe les deux éléments à effet Hall (6, 7) chacun à un des deux pôles magnétiques, ou, en d'autres termes, l'aimant est situé entre le premier élément à effet Hall (6) et le deuxième élément à effet Hall (7), par rapport à la pièce ou à la roue dentée (2).
