Definitions

  • the invention relates to a starting device Starting an internal combustion engine, with those in the preamble of the features mentioned in the main claim.
  • a starting device is known from DE 19702932 A1, where the one caused by an engagement relay Pinion's toe-in speed is reduced by the magnetic force between a feed winding and an engagement anchor while retracting the engagement anchor is reduced.
  • the pinion's toe-in speed follows at a tooth-on-tooth position between the pinion and a ring gear one Internal combustion engine a reduced impact speed and thus a reduced impact.
  • the toe-in of the Ritzels becomes the starter motor and thereby that Pinion operated at a greatly reduced speed.
  • the Period in which the toe-in speed and the Rotation speed of the pinion is reduced follows another period in which the toe speed or pulling force in the engagement relay is increased again.
  • the pre-engagement mechanism and the starter motor from the control and / or regulating device via separate circuits and each independent switching elements are to be controlled.
  • This is particularly in relation to the described state of the Technology is an advantage, as this means that the switching process for the Starter motor regardless of the moving masses of the One-track mechanism such as the engagement anchor or the Lane spring is. Switching on the starter motor can thereby better on the actual penetration depth of the Ritzels can be matched in the ring gear.
  • Another The advantage is the use of a sensor from which the Position of the pinion with respect to the ring gear determined can be.
  • An advantageous embodiment is in this Context the use of a displacement sensor from which for example a tooth-on-tooth position or the Penetration depth of a pinion in the ring gear derived can be. From a corresponding signal is for the Control and / or regulating device e.g. the tooth-on-tooth position recognizable so that the tax and / or Control device by rotating the pinion Control the pulsed current of the starter motor, and thereby Penetration by creating a tooth-gap position can ease.
  • the controls depending on the depth of penetration Control and / or regulating device the load-free or Shutdown or starting with partial load.
  • the starting process can be done with the help of a or several sensors can also be optimized in terms of time. Time optimization is e.g. possible because as soon as a recognized tooth-gap position is present Twist the pinion to create a tooth-gap position omitted. This recognition of a present Tooth-gap position is possible, for example, in that a displacement sensor detects the path covered by the pinion and as a path signal to the control and / or regulating device emits.
  • the pinion position is detected by means of sensors different ways possible.
  • a distance sensor can Example a field plate sensor can be used, the one on attached a toe-in component of the starter Magnetized foil senses, making it proportional Signals are generated.
  • Another method is for example the use of a force sensor on the toe-in force transmitting part, the force sensor in particular serves to detect a tooth-on-tooth position.
  • the speed the internal combustion engine is to be detected, for example thereby possible that indirectly from the pinion speed on the Speed of the internal combustion engine is closed.
  • FIG. 1 shows the schematic representation of a Starting device 10 according to the invention with a starter motor 11, the armature shaft 12 and a straight toothed Shaft-hub connection 13 with a drive shaft 14 is rotatably connected, the driver shaft 14 on the Armature shaft 12 is displaceable in a straight line.
  • the Driver shaft 14 is in turn via a freewheel 15 a pinion 16 connected.
  • the entrainment 14, the Freewheel 15 and pinion 16 are on armature shaft 12 can be moved in a straight line.
  • the starting device 10 with an electric solenoid 19, also a solenoid called, equipped, the lifting movement by a linearly displaceable rod 20 via one on the rod 20 hinged lever 21 via a driver 22 on the Entrainment 14 is transferred.
  • the solenoid 19, the Rod 20, the lever 21 and the driver 22 thus form a pre-engagement mechanism 23.
  • the solenoid 19 and the Starter motor 11 are controlled by a control and / or Control device 24 controlled.
  • the tax and / or Control device 24 comprises a microprocessor 25, a Switching unit 26 and a switching unit 27.
  • the Microprocessor 25 evaluates the signals from a speed sensor 28 and a displacement sensor 29 made in the pinion area are arranged in a fixed position.
  • the microprocessor 25 can alternatively, instead of the signals from the displacement sensor 29 Signals of an alternative to the path sensor 29 to be provided Evaluate force sensor 30.
  • the diagram according to FIG. 2 shows at a) the temporal voltage profile of U 10 , the voltage which is present at the input of the control and / or regulating device 24 or the starting device 10; in Figure 2b) the voltage curve U 19 is shown on the electric solenoid 19; Figure 2c) shows the time course of the voltage U 11 across the starter motor 11; Figure 2d) shows the time course of the feed path s 16 of the pinion 16; FIG. 2e) shows the idealized time profile of the current I 32 flowing via the start switch 32 .
  • the pinion 16 has reached the sprocket at the time t 1 as shown in Figure 2d and s can be seen from the Vorspurwegs sixteenth
  • the displacement sensor 29 detects the displacement s 16 covered by the pinion and outputs this as a displacement signal to the control and / or regulating device 24. If, for example, the displacement sensor detects the path of the pinion 16 at time t 2 and then at time t 3 , the control and / or regulating device 24 according to FIG. 2d recognizes a tooth-on-tooth position, since there is no change of path when that Path signal remains the same.
  • the microprocessor 25, as part of the control and / or regulating device 24, then controls the switching unit 27.
  • the starter motor 11 With a tooth-on-tooth position of the pinion with the ring gear, the starter motor 11, and thus the pinion 16, is to be rotated relative to the ring gear 34. Accordingly, the starter motor 11 is energized with a current pulse at time t 4 , so that, in the best case, after only one pulse at time t 41 , as can be seen from FIGS. 2c and 2d, a tooth-gap position has already resulted. If an impulse is not sufficient, the process can be repeated. Characterized in that the solenoid 19 continues to be operated with the clocked current I 19 , the pinion 16 finally engages by the toe-in force, and has reached a maximum engagement depth at time t 5 .
  • the starter motor 11 is switched off by the control and / or regulating device 24.
  • the starter motor 11 is only supplied with current once again when the control and / or regulating device 24 has detected a sufficiently large engagement depth of the pinion 16, the minimum penetration depth, by means of the displacement sensor 29 or the force sensor 30.
  • the control and / or regulating device 24 recognizes this by comparing the path signal of the path sensor 29 corresponding to the path covered by the pinion 16 with a predetermined value s v of the pinion path s 16 .
  • the force sensor 30 Since the force sensor 30 generates a force-proportional signal rather than a path-proportional signal, a tooth-on-tooth position or complete engagement up to a stop can also be reliably detected by means of the force sensor 30. In both cases, there are increased signals due to mechanical stresses, from which one can conclude one of the two positions.
  • the force sensor sends the respective signal to the control and / or regulating device 24, which compares it with predetermined reference values and can thus recognize, for example, a tooth-on-tooth position or complete engagement. If the control and / or regulating device 24 detects a sufficiently large engagement depth, for example at the time t 5 , FIG.
  • the microprocessor 25 controls the switching unit 27, which then starts the t 6 for some, for example as in FIG. 2 c shown, initially operates three pulses on average over time with partial load, whereby only a part of the maximum possible power of the starter motor 11 is transmitted. Thereafter, the starter motor 11 is operated at full load without clocking until the internal combustion engine starts, until the internal combustion engine turns automatically from time t 7 . If the clock stage in the switching unit 27 has a contact resistance, as is the case, for example, with field effect transistors, the voltage at the starter motor 11 is also reduced, as a result of which the power of the starter motor 11 is reduced again on average over time.
  • the starting device can be determined. If the starter motor 11 or, for example, the pinion 16 has exceeded a certain speed threshold, the control and / or regulating device 24 switches off the pre-engagement mechanism 23 and the starter motor 11 at time t 8 in an advantageous embodiment. By means of a return spring 35, the pinion 16 is subsequently moved out into a secured end position.
  • control and / or regulating device 24 processes the toe-in and engagement of the pinion 16 in the ring gear 34, as well as the turning and turning of the internal combustion engine in a purely time-controlled manner.
  • the starting device 10 does not require any sensors. Accordingly, after the start switch 32 has been closed, the control and / or regulating device 24 is switched on, whereupon the lifting magnet 19 initially only accelerates for a fixed predetermined time. In this first period, for example t 0 to t 2 , the pinion must at least ensure that the face of the ring gear is reached.
  • the starter motor 11 is briefly rotated with at least one current pulse, for example at t 4 .
  • at least this one current pulse it must be ensured that the pinion 16 can reach a minimum depth of penetration into the ring gear if the toe-in force is present.
  • the minimum penetration depth represents a size from which the pinion is considered to be at least partially engaged in the ring gear and a force can be transmitted between the tooth flanks of the pinion and the ring gear.
  • a third time period for example t 6 to t 7
  • the starter motor is operated at short intervals by the switching unit 27, so that a safe and sufficiently long time-averaged partial load operation is provided.
  • the starter motor 11 is finally operated at full load in a fourth time period, for example t 7 to t 8 , as a result of which the internal combustion engine is turned on and off.
  • the solenoid 19 and the starter motor 11 are automatically switched off by the control and / or regulating device 24 and the pinion 16 is brought into its starting position by the return spring 35.
  • control and / or regulating device In addition to this pure time control of the starting device 10, it is also possible for the control and / or regulating device to process the toe-in, engagement, turning on and spinning both partly in a time-controlled manner and partly in a path-controlled and / or force-controlled manner.
  • a partial time control as well as a partial path control is possible, for example, by the fact that the toe-in and engagement takes place, for example, in a way-controlled manner, while the turning on is carried out in a time-controlled manner with partial load and with full load.
  • Both partial time control and partial force control would mean that the toe-in and engagement would be force-controlled and the turning on with partial and full load would be time-controlled.
  • a pure time control of the sequence of the starting process, formed from toe-in, engagement, turning, turning and turning off the starting device can thus be optimized in its timing. If the displacement sensor 29 is used and by means of which an engagement is recognized immediately after the toe-in, the pinion does not have to be rotated to achieve a tooth-gap position of the pinion 16 and toothed ring.
  • the speed sensor 28 transmits indirectly via, for example, the pinion speed, the speed of the internal combustion engine to the control and / or regulating device 24, which is compared there with a preset value, so that after the self-running speed of the internal combustion engine reached at time t 8 Starting process is ended.
  • a possible embodiment of the displacement sensor 29 is e.g. on Field plate sensor, one on a track to be pre-tracked Component of the starter attached magnetized film 36 is sensed and thereby imprinted on the film magnetically opposite areas to the pinion path Generate proportional signal.
  • the force sensor 30 is on a part of the Attach toe-in mechanism 23.
  • a possible position is, for example, the attachment of the force sensor to the lever 21.
  • the speed sensor 28 is on the starting device 10 to attach that through this the speed of a Output elements is detected. Such a possible position would be, for example, close to the circumference of the freewheel 15 that its speed could be determined.
  • usable Design variants of the speed sensor 28 would be, for example a Hall sensor or also a field plate sensor.
  • the starting device 10 shown in FIG. 3 differs from that shown in FIG. 1 in that that the switching unit 27 for the starter motor 11 in this Case two different switching elements that can be connected in parallel 38 and 39 drives, here as field effect transistors are executed.
  • the toe-in of the pinion 16 takes place one of the manner described for Figure 1 and Figure 2 instead. If a tooth-on-tooth position by the microprocessor 25 recognized, this causes the switching unit 27 to Switching the switching element 38 on the starter motor 11 to operate a series resistor 40 with partial load, so that at a tooth-on-tooth position a gentle engagement is made possible.
  • the starter motor 11 is then also over this Series resistor 40 energized when the starter motor 11 first to be operated at partial load to turn the transmission off To protect sprocket 34 and pinion 16.
  • Has the pinion 16 a sufficient minimum depth of engagement in the ring gear 34 achieved under load isolation, so - as with the Variant 1 - the starter motor 11 initially with partial load and then fully energized.
  • FIG. 3 becomes the switching element from the switching unit 27 39 switched through, whereby the starter motor without Series resistor 40 is energized directly.
