- the invention relates to an electromagnetic relay, in particular a starter relay, to a starting device with a starter relay and to a method for actuating the starting device with a starter relay.
- a starter relay for a starting device which is used to start an internal combustion engine.
- the starter relay adjusts an axially displaceable mounted starter pinion in an engaged position with a ring gear of the internal combustion engine, whereupon an electric starter motor for driving the starter pinion is set in motion.
- the starter relay has in a housing on an adjustably mounted lifting armature, which performs an energizing movement of a pull-in winding and adjusts the starter pinion via a transmission lever.
- the starter relay comprises a switching armature, which is associated with a switching winding, is energized with energization of the switching winding of the switching armature and turns on the electric starter motor.
- the lifting armature in addition to the pull-in winding is associated with a holding winding, which can be energized as an alternative to the pull-in winding.
- a holding winding which can be energized as an alternative to the pull-in winding.
- the electromagnetic relay according to the invention has an axially adjustable armature and a pull-in winding, a holding winding and a switching winding.
- the armature is adjusted at a current supply of the pull-in winding between a starting position and a deflected position, wherein the
- Adjusting movement can be used as working or driving movement, in particular for the adjustment of a starter pinion in a starting device for an internal combustion engine.
- the holding winding is connected in series with the pull-in winding. In different phases, either the
- Feeding winding energized alone or both the pull-in winding and the series-connected holding winding are energized together.
- the switching coil can be used to connect an armature in the relay
- Impose switching movement in particular to start an electric motor.
- the relay preferably has two different, separately formed armature, of which the first armature forms a lifting armature, the
- Pick-up winding and the holding winding is assigned, and the second armature a switching armature, which is associated with the switching winding.
- the lifting armature and the switching armature are preferably mounted coaxially. But they are too
- Holding winding and the energized switching winding acts.
- the switching winding is advantageously energized only at a time in which the armature, which is associated with the retraction and holding winding, is already deflected by energizing one or both of these windings.
- the series connection of pull-in winding and holding winding has the advantage that with a relatively small current, a high magnetic force can be generated on the armature.
- Holding winding are both energized in a defined phase section due to their series connection, the current level is advantageously lower than in an exclusive energization of the pull-in winding. Of the Reduced current results in less heating of the relay, which improves the life of the relay.
- the current supply to the windings is effected by switches or transistors in the relay.
- the windings can be energized in different phases of the meshing movement in different ways alone or together.
- the pull-in winding and the holding winding are in the same magnetic circuit.
- the pull-in and the holding winding can be arranged on the same winding carrier.

- Feed winding is energized.
- the holding winding is dimensioned smaller than the pull-in winding and has, for example, a smaller number of turns than the pull-in winding, so that, for example, an exclusive energization of the holding winding a smaller magnetic force is applied, which acts on the adjustable anchor.
- the pull-in winding and the holding winding are advantageously independently energized. This makes it possible, especially in the different phases during the Einspurphase either only the
- the anchor is in particular by the force of a spring element in the
- the Einspurphase includes all phase sections in the transfer of the armature from its initial position in the adjusted Einspurposition, which preferably represents the maximum deflected position of the armature. Also, the holding of the armature in the Einspurposition is encompassed by the Einspurphase. In the case of a starting device and a starter relay engages in the meshing position, the starter pinion in the ring gear of the internal combustion engine.
- the switching winding which can be started in the case of an embodiment of the electromagnetic relay as a starter relay for a starting device of the electric starter motor, advantageously acts in a different magnetic circuit.
- the pull-in winding and the holding winding are in a first magnetic circuit and the switching winding in a second magnetic circuit.
- the pull-in winding and the holding winding are energized in different phases of the Einspurphase in different ways.
- the pull-in winding and the holding winding are energized in different phases of the Einspurphase in different ways.
- Holding winding whereby the heating of the starter relay is limited.
- the energization of the holding winding takes place in particular in a phase in which the armature has already reached its Einspurposition, in which the starter pinion is in engagement with the ring gear of the internal combustion engine.
- This phase can also be referred to as a waiting phase, which occupies the starting device when the internal combustion engine is switched off, but should be restarted within a short time, for example in the case of a traffic light stop the Vehicle in which the internal combustion engine including starting device is installed.
- a further phase section adjoins the first phase section of the single-track phase, in which only the pull-in winding is energized, in which only the holding winding is energized.
- the holding winding is energized in this situation even before reaching the maximum deflected position of the armature, so that with the
- the holding winding has a magnetic force acting on the armature, which adjusts this in the direction of the deflected position. With the energizing of the holding winding acts in comparison to the pull-in winding a smaller
- Starter pinion is maintained, but a reduced current acts in the starter relay. As soon as the internal combustion engine is to be started, the switching winding is energized, whereby the electric starter motor is started.
- Fig. 1 is a starting device for an internal combustion engine with a
- Starter relay for adjusting a starter pinion

- Starter pinion 2 between the non-functional position and the engaged position is implemented.
- the rotating drive movement on the shaft 5 and the starter pinion 2 is generated by means of an electric starter motor 1 1, which via a
- Planetary gear 12 is coupled to the shaft 5. Upon actuation of the electric starter motor 1 1, the shaft 5 and thus the starter pinion 2 is rotated.
