Definitions

  • the invention relates to a starter protection circuit for the starting device of an internal combustion engine of a vehicle, in particular a motor vehicle, according to claim 1, part 1 (compare JP-A-58 197 469).
  • the internal combustion engines of vehicles are equipped with an electrically operated starting device.
  • an engagement relay can be actuated, which connects a starter device to a battery of the vehicle and produces a mechanical connection between the starter and the internal combustion engine via a pinion arrangement.
  • the driver of the vehicle opens the start switch by releasing the ignition key, as a result of which the engagement relay drops out and the starter is deactivated.
  • the starter is only suitable for short-term operation that is, it can only withstand a warming caused by the relatively large starter current for a short time during a starting process. In this respect, there is a starter failure (mostly total damage due to overheating) if, for example, the starter switch "gets stuck", since this leads to continuous operation of the starter for which it is not designed.
  • the starter protection circuit according to the invention with the features mentioned in the main claim has the advantage that sticking of the starter switch or the like does not lead to destruction of the starting device, in particular its starter device. If the starter z. B. actuated for an impermissibly long time as a result of a fault (in particular the start switch gets stuck), a thermal switch assigned to it responds. The response of the thermal switch due to a corresponding heating of the starter device has the result that a relay is actuated which interrupts the starter operation. In this respect, the starter is switched off before it destroys itself due to the developing heat. In order to be able to restart the starter after a cooling-down period despite the stuck start switch, a relay actuation button is provided. This can preferably be operated from the driver's seat. The actuation causes the relay to switch, so that the starter is no longer interrupted.
  • the starter protection circuit according to the invention therefore not only offers overload protection of the starting device, but also gives the possibility to restart an initially interrupted starter operation despite an error.
  • the relay has a latching circuit.
  • the relay position which interrupts starter operation can therefore be maintained by the self-holding circuit.
  • the relay actuation button preferably has a break contact which is located in the self-holding circuit of the self-holding circuit. The actuation of the relay actuation button interrupts the self-holding circuit, so that the previously energized relay drops out again, which means that starter operation is possible again if the thermal switch has returned to its cold switching state.
  • the thermal switch has a normally open contact when a limit temperature is exceeded. If the limit temperature is exceeded, this make contact closes, which excites the winding of the relay and assumes a switching state that interrupts starter operation.
  • the thermal switch can be coupled directly to the starter via a heat-conducting connection, so that it detects the temperature of the starter and accordingly assumes its cold switching state or its hot switching state.
  • the thermal switch may be flowed through by an actuating current of an engagement relay of the starter.
  • the actuation current activates the engagement relay and thus the starter. It is thus ensured that the starter also operates when the actuation current occurs, so that monitoring the actuation current is equivalent to monitoring the starter.
  • the actuating current itself heats the thermal switch so that the thermal switch responds when a predetermined current flow duration is exceeded. The starter operation is therefore monitored over time.
  • the arrangement can preferably be designed such that the relay switches off the supply voltage of the engagement relay. As a result, the engagement relay drops out, so that the current supplied directly from the vehicle's battery to the starter is interrupted.
  • the relay has a make contact and a break contact, the make contact being in the self-holding circuit and the break contact being connected downstream of the start switch and being arranged in a circuit associated with the engagement relay.
  • the relay for the interruption of the starter operation keeps in latched state via the mentioned normally open contact.
  • the break contact makes the engagement relay de-energized.
  • the closer of the thermal switch is connected in parallel to the closer of the relay, so that when the thermal switch responds, the relay is energized and - after a cooling phase - the relay remains held in place by the normally open contact assigned to it, even though the closer of the thermal switch has returned to its open position .
  • the thermal switch is designed as a change-over contact, the changeover contact of which is in series with the start switch and whose pole, which is connected to the changeover contact in the cold switching state, is connected to the engagement relay via an opener of the relay and which is also connected in the hot switching state the switch-connected contact pole leads to the winding of the relay.
  • the engagement relay is accordingly supplied via the make contact. If the relay picks up by responding to the thermal switch, the break contact interrupts the circuit leading to the engagement relay, which means that the starter operation is interrupted. At the same time, the make contact then holds the relay in the pulled position via a self-holding circuit. An opener of a relay actuation button is located in this self-holding circuit, so that during its operation the relay can be returned to its dropped position and - after the cold switching state of the thermal switch has been taken - a renewed starter operation can take place.
  • the thermal switch has an opener, one first pole of which is connected to the ignition switch and the other, second pole of which is connected to the engagement relay via an opener of the relay, and that one end of the winding of the relay is on the second pole and the other end of the winding is connected to the starter pole of the start switch via the break contact of the relay actuation switch.
  • the engagement relay is supplied via the thermal switch and the normally closed contact of the relay.
  • the winding of the relay is in the non-excited state Condition as both winding connections are at approximately the same potential. If the thermal switch responds, i.e.
  • the thermal switch has a make contact, one pole of which leads to a battery of the vehicle, preferably to its positive pole, and the other pole of which leads to the connections of a pull-in and a holding winding of the relay , that the other connection of the holding winding is connected to the starter-side pole of the start switch via the opener of the relay actuation switch, which also leads to the engagement relay via an opener of the relay, and that the other connection of the pull-in winding is connected to the battery, preferably to its negative pole .
  • the engagement relay is controlled by the start switch, a connection that supplies via the normally closed contact of the relay.
  • the relay position is indicated by a control lamp. As a result, the driver is always informed about the current operating status.
  • the starter protection circuit 1 of FIG. 1 is connected to a battery 2 of a vehicle, not shown, and interacts with a starting device or a starter 3 of an internal combustion engine of the vehicle, also not shown.
  • the positive pole 4 of the battery 2 is connected via a line 5 to a terminal 30 of the starter 3.
  • the positive pole 4 is connected to a battery-side pole 6 of a start switch S, which is located on the dashboard of the vehicle and can be actuated with the ignition key.

  • the self-holding circuit 29 of the self-holding circuit 28 formed in this way contains the relay actuation button D designed as a break contact 32, actuation of this button, which is preferably possible from the driver's seat, causes the relay R to drop, which, owing to the position in the closed position, faulty start switch S is again activated via the break contact 10, the engagement relay 25, so that the starter operation can be resumed.
  • FIG. 2 shows a further exemplary embodiment of a starter protection circuit 1, the same parts being provided with the same reference symbols.

  • a self-holding circuit 28 is also present here, which has a self-holding circuit 29.
  • the thermal switch T cools down again, so that the changeover contact 35 returns to its cold switching state, so that there is a connection between the terminal 36 and the pole 37.

As a result, the starter 3 stops operating.
  • the thermal switch T As long as the thermal switch T is in its cold switching state (according to FIG. 3), there is a bridging of the connections of the winding 23 of the relay R (terminals 85 and 86). As soon as, however, as mentioned above, the thermal switch T assumes its hot switching state, in which the opener 52 interrupts the bridging, there is a connection between the positive pole 4 of the battery 2 and the terminal 50. This connection runs via the in the closed position located start switch S, the break contact 62 of the relay actuation button D and the winding 23 (in parallel also via the control lamp L). The current flowing through this connection is sufficient to keep the relay R in its energized state; however, it is not large enough to hold the engagement relay 25 in the energized state.
