Definitions

  • the invention relates to a Einspurrelais for the starter of an internal combustion engine with a relay winding, with an armature with which a lever for meshing a pinion of a starter in a ring gear of the internal combustion engine can be actuated and with a switch on the armature, in the rest position a first Circuit for slowly starting the starter via a resistor closes and turns on the energization of the relay winding the starter in a second circuit directly to the electrical power supply to drive the internal combustion engine after meshing of the pinion with maximum electrical energy.
  • the invention further relates to a starter for an internal combustion engine with a Einspurrelais, in particular with the features described above, with a Zitzelverdus driving, wherein the Zitzelverdus sensible comprises the switch with a resistance to slow start of the starter.
  • a single-stage system has a pull-in winding and a holding winding. With the Einspurwicklung the armature and the movable pinion is meshed and held with the holding winding in the engaged state. The single-track winding generates a higher magnetic flux than the holding winding, so that the combination of pull-in and hold winding reduces the total amount of relay heating compared to the starter with only one pull-in winding.
  • a two-stage starter works with a slow scrambler or twister in the first stage. In the first stage, the current at the starter is reduced by a switched electrical resistance, and in the second stage, the starter is directly connected to the electrical power supply, thus turning maximum.
  • a two-stage system usually has only one pull-in winding and no separate hold-up winding.
  • the resistance for the first stage is integrated in recent developments as a resistance wire meandering in the relay winding or arranged outside.
  • EP 0 953 200 B1 describes an engagement relay for a starter of an internal combustion engine with a switch as a changeover contact, which switches in the rest position the starter motor for smooth starting via a resistor and in the working position directly to the electrical supply, in which case the resistor is switched off.
  • the resistor is meandering integrated as a resistance wire or arranged on the outside of the pull-in winding.
  • An essential idea of the invention is to arrange the resistor outside the relay winding, thus reducing the heating behavior in the relay and to concentrate the resistor to a compact size.
  • the object is achieved with a Einspurrelais in that the first circuit has a compact resistor made of resistive material, which is spatially separated from the relay winding. This results in a simple construction, since the resistance material is easy to arrange and does not have to be integrated complicated inside and outside the relay winding. This creates a simplified production with high rationalizing potential.
  • the heating of a resistance wire according to the prior art had the disadvantage that it can melt at too high currents, thus becomes electrically conductive and may undergo an electrical connection to the relay winding, which could lead to a faulty control of the starter and thus to a total failure of the starting system. Due to the spatial separation of the resistance, the necessary Verfstrom can be easily adjusted by adjusting the resistance.
  • the resistor is formed on the changeover switch. This has the advantage that the resistor is disconnected from the relay winding and does not directly cause a heating of the relay winding, so that burning through the resistor has no direct influence on the relay winding. Blowing the resistor with the prior art wound resistance wire is also prevented by employing a compact, thicker resistance material.
  • the resistor is fixedly arranged on the switch. From the contact plate at anchor thus the first circuit is closed with the stationary resistor. The contact plate of the armature then closes after extending the second circuit.
  • the resistor is alternatively movably arranged at the armature for switching, the resistor conducts only in the first circuit and in the second current is a good electrically conductive material, in particular a contact plate is connected ,
  • the resistor is designed as a plate and thereon a conductive contact plate fixed to the armature, wherein the contact plate is adapted to the contacts of the second circuit.
  • the relay winding is formed with a pull-in and a holding winding.
  • the pull-in winding and at the same time a low Verwindstrom for the starter driven and after reaching the armature in its extended position, i. a switching of the second circuit of the pull-in winding switched to the holding winding, which generates a lower heating of the Einspurrelais, since less current and a smaller magnetic flux is generated.
  • the object is also achieved with a starter for an internal combustion engine, in that the resistor is made of compact resistor material and is spatially separated from the relay winding of the single track relay.
  • the resistor is an ohmic resistor and may be located in the electrical circuit on the electric starter at any location where it is electrically isolated from other components.
  • the resistor can also be accessible from the outside of the housing to be able to be adjusted individually.
  • the resistor is arranged to Einspurrelais according to the features described above. It goes without saying that the features mentioned above and those yet to be explained below can be used not only in the respectively indicated combination but also in other combinations.
  • FIG. 1 is a schematic side view of a Einspurrelais
  • Fig. 3 is a schematic side view of an indented Einspurrelais
  • Fig. 4 is a Fig. 3 corresponding electrical circuit diagram of a starter with engaged Einspurrelais.
  • Fig. 1 shows a schematic side view abstracts and simplifies a Einspurrelais 1 with a relay winding 2 and a movable within the relay winding 2 arranged armature 3.
  • the armature 3 is acted upon springs, not shown, against the armature 3 when energized the relay winding 2 is moved in the opposite direction and thus a not shown pinion in a ring gear of an internal combustion engine ein- moves. So that the pinion can be gently engaged by the starter and does not collide tooth to tooth with the pinion and ring gear, a first stage with a small starting current is provided in the two-stage starter and a second stage, in which the starter is supplied with the full electrical power supply.
  • a changeover switch 4 is provided for switching the two-stage system.
  • the armature 3 closes at rest a first stage with a small starting current is provided in the two-stage starter and a second stage, in which the starter is supplied with the full electrical power supply.
  • a changeover switch 4 is provided for switching
  • the resistor is formed directly on the armature as a resistance plate 5 made of a compact resistance material.
  • the resistance plate 5 connects two electrically conductive terminals 6, 7 of the first circuit.
  • Terminal 6 is also called terminal 45 and is preferably grounded.
  • Terminal 7 is called terminal 5Oi because this terminal is controlled by a pilot control relay with a small control current.
  • On the resistance plate 5 is an electrically conductive contact plate 8, which has no significant ohmic resistance.
  • the contact plate 8 connects contacts 11, 12, which are designated by terminal 30 and 45, preferably have a cone-shaped contact head. The contact plate 8 closes a second circuit when the armature 3 has actuated a lever and has thus engaged the pinion from the starter into the toothed rim.
  • the Einspurrelais is applied to the terminal 5Oi by operating a non-illustrated pilot control relay with power.
  • Current flows through the resistor 5 to the starter 10.
  • the starter 10 thus slowly rotates the pinion, which is engaged in the ring gear for starting the engine. By turning a blocking is prevented.
  • the starting current flows a few fractions of a second, since the Einspurrelais 1 via the armature 3, the switch 4 is actuated and the current, as shown in Fig. 4 via the terminal 30 to the starter 10 passes.
  • FIG. 3 shows in a schematic side view corresponding to FIG. sees, the engagement relay 1 with a disengaged armature 3 due to energization of the relay winding. 2
  • the relay winding 2 comprises a pull-in winding and a holding winding.
  • the pull-in winding When closing the contacts 11, 12 of the second circuit with the contact plate 8, the pull-in winding is turned off and the holding winding is turned on, so that the Einspurrelais 1 undergoes less heating, since the holding winding is driven with a lower current. This allows a longer life of the Einspurrelais 1 with frequent and longer starts.
  • the resistor 5 which may be of any shape on the armature and made of any resistance material, interrupts the terminals 6, 7, which may also be referred to as normally closed contacts, from the first circuit.
  • Fig. 4 shows an electrical circuit diagram a closed second circuit at the changeover switch 4 due to the energization of the Einspurrelais 1 with a relay winding 3 or according to a preferred embodiment with a lower energized holding winding.
  • the resistor 5 can be designed and configured optimized for the rotation. Influences on the relay winding 2 or holding winding are no longer to be considered, since a spatial separation to the resistor 5 is provided.
  • the construction is significantly simplified and the heating behavior of the input relay 1 is reduced, which leads to an extension of the maximum duty cycle or to a higher number of operations.
  • the production is much easier and cheaper, since a winding of a resistance wire is avoided.
