Definitions

  • the invention relates to a circuit arrangement for starting an internal combustion engine with at least one starter, comprising a starter motor, a Einspurrelais, a switching relay and a control relay, wherein the control relay is controlled by an ignition switch and a current path from the starter motor by means of the switching relay is switchable.
  • the invention further relates to a method of a starter control, in particular a circuit arrangement of a starter, preferably parallel switchable starters, for starting an internal combustion engine, wherein the starter with a starter motor, a control relay, a Einspurrelais and a switching relay is formed, the Einspurrelais of Control relay is controlled and the switching relay is driven by Einspurrelais.
  • starting devices which are arranged in parallel and connected, known to start an internal combustion engine.
  • Such an internal combustion engine is usually very large and has, for example, a displacement of several 10 or 100 liters.
  • the Einspurvor Vietnamese may have different Einspur profession because a tooth-on-tooth position of a starter pinion in the sprocket requires a longer Einspurvorgang than a tooth-gap position.
  • the main current for the at least two starter motors is released at the same time, only when all closing operations have been carried out.
  • the following relays are switched in sequence, or closed: It is driven by a Zündstrompfad in a control relay, which releases a Einspurrelais. If all single-track relays are energized, at least one switching relay is switched through, which releases the main current for each starter motor. The starter is switched off in the same sequence. The energization of control relay, then Einspurrelais and last switching relay is interrupted, so that the associated current paths are opened.
  • the DE 10 2005 006 248 A1 describes a starter assembly for starting an internal combustion engine with multiple starters in parallel.
  • the switching relay is controllable at least in the switch-off depending on the occurrence of a defined event. This has the advantage that the switching relay earlier in time can interrupt a current path from the starter motor, in particular a main current path, so that a backward current is avoided.
  • the switching relay can release the current path of the starter motor so defined that significantly reduced in the shutdown when licking a starter pinion sprocket, or even prevented.
  • An idea on which the invention is based is therefore to turn off the starter motor earlier in time than in the above-described prior art when switching off the at least one starter, in order to avoid pinion prellers.
  • Pinion prellers occur when the starter pinion moves again in the direction of the sprocket of the internal combustion engine and thus causes wear on the sprocket and / or the starter pinion.
  • the defined event is defined by the fact that the circuit arrangement is formed electromechanically.
  • the occurrence of the defined event at the shutdown is stable and safe switching realized and also constructed as simple and inexpensive.
  • the switching relay is arranged in the switchable from the control relay current path of the Einspurrelais.
  • the switching relay is switched off simultaneously with the Einspurrelais.
  • the switching relay is not switched off, as in the above-described prior art, by the Einspurrelais.
  • the time for switching off the current path for the starter motor in contrast to the prior art, moved much further forward, so that pinion spellers are avoided or significantly reduced in intensity. Abrasive behavior is reduced, thereby increasing the life of a starter.
  • the switching relay has two control switches.
  • the first control switch is in Einspurvorgang the Einspurrelais that closes simultaneously by reaching the maximum Einspurtiefe when meshing a switch through which the switching relay can be energized.
  • a second control switch is provided in order to control the switching relay in a specific relationship in the Ausspurvorgang or shutdown of Einspurrelais.
  • the second control switch is the control relay.
  • the control relay is actuated both in the single-track and in the Ausspurvorgang as a second control switch actually before the first control switch.
  • Switching relays and control relays as well as single track relays are thus linked together as electromechanical switches.
  • the control relay switches both a current path from the latching relay and a current path from the switching relay.
  • the single-track relay switches a current path from the switching relay.
  • the circuit arrangement is designed as electronic control with electronic circuit breakers. This has the advantage that the switching times, in particular of the switching relay can be adjusted even more individual, so that the intensity of sprocket bouncers can be better suppressed.
  • the starters are for Switching of the main current for the respective starter motor in the starter serially coupled so that they are turned on only when all Einspurrelais have closed a switch on Einspurrelais.
  • the switching relays are each individually switched off by the control relay in the respective starter.
  • the object is also achieved by a method in that the switching relay is switched off depending on a defined event.
  • the defined event is previously determined manufacturer and operating side and can be realized either electromechanically or electronically, for example by detecting a specific sensor value by means of a sensor.
  • a computer program product may be provided which is loaded with program instructions into a program memory of a controller and performs the method described herein when the program is executed in the controller.
  • a computer program product has the advantage that it can be implemented as a module in already existing controllers and that it can easily be adapted to individual and application-specific specifications, whereby a correction to empirically determined values is very easily possible.
  • the switching relay is switched off simultaneously with the Einspurrelais of the control relay.
  • An electromechanical control has the advantage that a long service life with a high reliability can be realized.
  • the switching relay is switched off in time and / or set before the Einspurrelais off.
  • an electronic or electromechanical, adjustable time delay element can be provided in order to predefine a defined time difference between the switching off of the switching relay and the latching relay in the switch-off process, in order to avoid so-called pinion bouncing, that is to say a readjusting movement after the picking up of a starter pinion.
  • the switching relay is only switched on when the control relay and the Einspurrelais are closed. This avoids that the starter motor is energized early. Furthermore, it is thus possible according to the invention to interrupt the current for the starter motor solely by the control relay.
  • the respective switching relays for the respective starter motor are only turned on when all Einspurrelais and in particular all control relays have closed switch. This ensures that each individual starter is not overloaded and all starters start with a high level of safety with a small tolerance range at the same time the internal combustion engine.
  • Single-stage single-track relays are used for small internal combustion engines. A required rotational movement of the starter pinion takes place for example via a coarse thread in the starter.
  • the Einspurrelais is formed in two stages in a starter arrangement with multiple starters, with a pull-in winding and a holding winding.
  • the pull-in winding is connected in the current path of the switch motor, so that the starter motor is slightly turned when meshing to avoid a tooth-on-tooth position as possible, so that a tooth-gap position is generated with high security between sprocket and starter pinion ,
  • the Fig. 1 shows a schematic circuit diagram of a circuit arrangement for starting an internal combustion engine by means of a starter 1, which, as in the Fig. 2 shown, connected in parallel with a second and can be arranged.
  • the starter 1 comprises a starter motor 2 and a control relay 3, which is arranged in an ignition path 38 with a mechanically or electronically controlled ignition switch 8.
  • a Einspurrelais 4 is provided to Swiss-Shiffer a starter motor 2 and a control relay 3, which is arranged in an ignition path 38 with a mechanically or electronically controlled ignition switch 8.
  • the Einspurrelais 4 is provided to Swiss-puren an unillustrated starter pinion in the ring gear of an internal combustion engine, not shown.
  • the Einspurrelais 4 has a Einspurwicklung 5 and a holding winding 6.
  • the Einspurwicklung 5 is high impedance, so that the starter motor 2 undergoes a small cranking to avoid a tooth-on-tooth position of starter pinion and ring gear when meshing. If the Einspurrelais 4 Solutionspurt, the Einspurwicklung 5 is turned off by a mechanically coupled switch 53 and the Einspurrelais 4 is held with a small current in the engaged state. The Einspurrelais 4 closes upon reaching the maximum Einspurtiefe a switch 54, so that a switching relay 7 is energized and the internal combustion engine with a maximum current can start the engine.
  • the battery positive pole is designated as terminal 30 and the earthing as terminal 31. Between the battery positive pole terminal 30 and a starter drive terminal 50, the ignition switch 8 is arranged.
  • the switching relay 7 is coupled to a second control switch to avoid in the Ausspurvorgang the starter pinion whose potential movement back towards the ring gear.
  • This second control switch is preferably activated as a function of the occurrence of a specific, defined event.
  • the defined event is "free" selectable.
  • the event can be perceived by means of a detector, or also by means of a switch.
  • the switching relay 7 in a switchable by the control relay 3 current path 50.5 arranged by Einspurrelais 4.
  • the switching relay 7 which turns on the main current for the starter motor 2 at a terminal 45, time significantly earlier than in a known from the prior art circuit or starter control, are switched off, so that pinion bumpers are avoided and thus wear on the ring gear or on the tooth flanks of the starter pinion or on one of the two gears, significantly reduced and / or prevented.
  • the switching off of the switching relay 7 is exactly defined by an event dependent.
  • the Einspurrelais 4 is thus switched off simultaneously with the switching relay 7 from the control relay 3.
  • thermal switch 9 is connected in series with the control relay 3 in the starter 1.
  • the thermal switch 9 generates the same turn-off behavior as opening the ignition switch 8.

  • the control relay 3, 3 'then switches in each case a Einspurrelais 4, 4'.
  • the Einspurrelais 4, 4 ' may each have different Einspur profession, since for example in a starter 1, the tooth-on-tooth position is present and the starter pinion is slightly energized by the starter motor 2 by a high-impedance Einspurwicklung 4.
  • the starter motors 2, 2 ' are evenly loaded when starting the internal combustion engine, the starter are connected in series' so that the switching relay 7, 7' for switching a main flow or main flow path 30.2, 30.2 'at terminals 45, 45' of the starter motors 2, 2 'are energized only when all Einspurrelais 4, 4' are fullyLespurt.
  • a switch 54, 54 'on Einspurrelais 4, 4' is closed.
