Definitions

  • the invention relates to a device according to the preamble of the main claim.
  • sensor systems for detecting the angular position of a shaft of the internal combustion engine, in particular the crankshaft or the camshaft.
  • Such systems are designed, for example, as segment systems in which sensor disks rotate with the shaft, the circumference of which is provided with a number of segments proportional to the number of cylinders of the internal combustion engine, ie elongated marked areas.
  • the number of segments is half the number of cylinders.
  • the number of segments is equal to the number of cylinders, since it is known that the crankshaft rotates at twice the speed of the camshaft.
  • Each segment is assigned to a cylinder (s) of the internal combustion engine (when the crankshaft is detected), and every ignition or injection process is controlled depending on the passage of the associated segment.
  • the leading edge of the segment is recognized in a stationary receiving element and the control processes for the internal combustion engine are triggered by suitable time control over the entire segment length.
  • segment systems with segments of the same size have the disadvantage that it is not possible to assign them sufficiently for a distributor-free or two-circuit (eg eight-cylinder engine) high-voltage distribution.
  • encoder disk is required depending on the number of cylinders.
  • these encoder disks also differ from one vehicle type to another. This means that a large number of different encoder disks is required, which complicate both the manufacture and the storage.
  • the device according to the invention with the characterizing features of the main claim has the advantage that a modular system can be built for different types of vehicles and different numbers of cylinders. Depending on the number of cylinders of the internal combustion engine, segments can be arranged on a uniform encoder disk.
  • the device is particularly simple since the same components can be assembled. The device can thus be used for several different systems. It is also possible to produce only a single, uniform segment part, which can then also be used for the segments without marking properties by removing the extension and while maintaining the crescent-shaped contour. You only have to take care once when dimensioning that the calculated unbalance is zero.
  • FIG. 1 shows a basic illustration of a sensor disc with arranged segments
  • FIG. 2 shows a one-part segment before and after removal.
  • Fig. 1 10 denotes a sender disk which rotates with the crankshaft or the camshaft of an internal combustion engine.
  • two components 11, 12 are arranged, which are operatively connected to a spatially fixed receiving element 13.
  • the type of interaction of the components 11, 12 with the receiving element 13 can be very different.
  • the components 11, 12 can be punched out of ferromagnetic sheet metal or made of cast iron, and an inductive sensor is used as the receiving element 13, which already has a magnetic flux in the idle state.
  • Both components 11, 12 are of equal length and are diametrically opposite. Furthermore, the components 11, 12 consist of a sickle 14 or 14a and a nose 15 or 15a with steeply falling flanks, both of which are then arranged one behind the other in the circumferential direction of the encoder disk 10.
  • the sickle and the nose are two separate parts that differ depending on component 11 or 12 Lich arranged to each other.
  • the sickle 14 and the sickle 14a are thus of the same design and are labeled with different digits only for clarity. The same applies to the noses 15, 15a.
  • only two parts (sickle, nose) need to be manufactured in order to build up the different components 11 and 12.
  • the sickle 14 is arranged so that the inclined plane of the sickle 14, ie the side facing the circumference of the encoder disc 10 or the receiving element 13, rises against the direction of rotation of the encoder disc.
  • the nose 15 is arranged at the foot of the sickle 14, ie at the outlet of the inclined plane.
  • the nose 15 and the sickle 14 must connect directly to one another to avoid false impulses. Furthermore, the nose 15 and the sickle 14 have the same overall height.
  • the nose 15a faces the center of the encoder disk 10. Furthermore, the sickle 14a is displaced such that the side of the component 12 facing the circumference of the sensor disk 10 has a circular contour. The center of this contour coincides with the center of the encoder disc 10. This circular contour is achieved by moving the outlet of the sickle 14 from the base of the nose 15 to its head. It can be seen that the head of the nose 15 must also be circular. The head of the nose 15 must fit seamlessly into the contour of the component 12. It therefore has the same radius as the inclined plane of the sickle 14. Thus, it is possible to selectively assemble both components 11 and 12 with a uniform sickle 14 and a nose 15. It is therefore easy to build a modular system. However, the unbalance ratios due to the different center of gravity ratios and the centrifugal forces thus acting on the components 11, 12 must be taken into account. The calculated unbalance must always be zero.
  • the encoder disc is attached to the crankshaft of an internal combustion engine, and is therefore suitable for controlling four-cylinder engines. If the encoder disk 10 is to be used for an internal combustion engine with eight cylinders, three components 12 and one component 11 are to be arranged on the encoder disk at equal angular distances. A nose 15 is only necessary once for the assignment of the pulses to the individual cylinders.
  • the component 11 in one piece, as shown in FIG.
  • the nose 15b and the sickle 14b are thus firmly connected to one another.
  • the nose 15b has to be removed up to the sickle outlet while maintaining the circular contour of the sickle part. This can e.g. done by milling.
  • the length of the component must not be changed.
  • the receiving element 13 first detects the front flank of the component 12, for example the component 12.
  • the ignition process can then be triggered, for example, between the start of component 12 and an n angular position corresponding to the rear flank of nose 15a.
  • the signals generated by the components 11, 12, 15 and 15a in the receiving element 13 are fed to a control circuit for the ignition, injection and the like of the motor vehicle. It is therefore an exact to Order of the ignition pulses for a distributor-free high-voltage distribution possible with a single encoder, the more precise mode of operation is generally known and is therefore not described in detail here.
