Definitions
- the invention relates to a starter for an internal combustion engine according to the preamble of the independent claim.
- a starter is described for example in the Automotive Handbook of Bosch, 25 Aufläge, p.986 in the embodiment as a thrust screwdriver starter, which is controlled by a so-called engagement relay.
- This relay assumes the functions of indenting, i. Tracing the pinion of the starter motor in the ring gear of an internal combustion engine, and switching the main current of the starter motor.
- a so-called engagement relay assumes the functions of indenting, i. Tracing the pinion of the starter motor in the ring gear of an internal combustion engine, and switching the main current of the starter motor.
- starter design requires only a single relay and can thus be produced relatively inexpensively, on the other hand arise for the Einspurvorgang and for switching the high motor current difficult working conditions.
- the switching device for the main current of the starter whose maximum possible torque is already generated when cranking out of a standstill out. If in this case the pinion of the starter motor is not fully into the ring gear of the Internal combustion engine istikspurt, it can at least over the life of the starter away to unduly large loads of the teeth come with the risk of breaking out of one or more teeth.
- the starter according to the invention with the features of the independent claim has the advantage that by the meshing of the pinion with a delayed connection of Partial windings of the field winding the characteristics of the starter motor are influenced so that the teeth between the starter motor and engine during Einspurvorgang is significantly less burdened. Furthermore, the speed behavior during startup of the starter, in particular by the shift of the idle speed, positively influenced. By the addition of additional pole pairs with the associated part windings of the field winding the maximum available torque of the starter is only reached at a time when the
- the partial windings of the field winding can be operated either in series and / or in shunt to the armature of the motor. While the torque of the motor when starting the motor is reduced by reducing the partial windings operated in series, it is possible by the connection of individual partial windings in shunt to armature to straighten the speed characteristic and the speed behavior of the starter less dependent on
- Exciter winding are arranged on separate poles of the stator, in particular, when the stator is six-pole formed with six partial windings on three pole pairs, wherein the partial windings in pairs on opposite poles are applied to the stator circumference. This results in their switching and delayed connection a symmetrical arrangement of the exciter part windings, whereby the startup of the engine is improved.
- Semiconductor devices are used, preferably transistors or GTO (gate turn-off) thyristors.
- a particularly simple and inexpensive starter design is obtained in a single-stage energization of the starter motor, a pull-in winding switches together with a holding winding of the Einspurrelais a normally open, energized on the first one or more exciter part windings of the starter motor and the starter motor until the end of Einspurterrorism the Einspurrelais on the all
- the holding winding and the pull-in winding of the Einspurrelais preferably sit on the same relay core. In the case of a single-stage energization they are switched in the same direction, whereby the necessary total flux is achieved with a smaller number of turns and / or lower excitation current. In opposite flooding of the common relay core, as used in two-stage energization of the motor, the winding with the smaller flooding are used to dampen the switching process.
- the number of turns and the excitation currents of the holding winding and the pull-in winding are expediently chosen so that the holding winding with a high number of turns and a sufficient
- Excitation current causes the switching operation of the Einspurrelais, while the intake winding is equipped with a significantly lower number of turns, but a much higher excitation current leads, which is sufficient to easily twist the armature when meshing.
- FIG. 1 shows a schematic representation of a thrust
- FIG. 2 shows a circuit diagram of a single-stage energized starter in a conventional design with a series-connected winding and optionally an additional shunt winding;
- FIG. 3 shows a circuit diagram of a single-stage energized starter with a series-closed-loop winding in accordance with the invention
- FIG. 4 shows a circuit diagram of a two-stage energized starter with a series-closure excitation winding in accordance with the invention
- FIG. 6 shows a third circuit diagram of a two-stage energized starter according to the invention, wherein the field winding of the starter motor partially as
- a series winding and partially designed as a shunt winding are shown.
- FIG. 1 shows schematically the mechanical structure of the starter 10 according to the invention in the embodiment as a push-screw drive starter for an internal combustion engine.
- the starter 10 has a starter motor 12, the output shaft 14 has a coarse thread 16 which cooperates with a corresponding female thread in a driving shaft 18.
- the output shaft 14 via an unillustrated, interposed
- the Mit technicallyschaft 18 is fixedly connected to the outer ring of a freewheel ring 20, the inner ring carries a pinion 22.
- the pinion 22 and the freewheel 20 are on the output shaft 14 to a Stop 24 mounted axially displaceable.
- the pinion 22 is thereby meshed in a ring gear 26 of an internal combustion engine, not shown.
- the axial displacement takes place by means of a switching device shown in detail in the following figures in the form of a
- Relay assembly 28 which engages via a reversing lever 29 and a Einspurfeder 32 on the freewheel 20.
- a voltage source 34 of the arrangement is a battery which is connected to its negative pole 31 to ground and with its positive pole 30 on the one hand directly and on the other hand via a
- Ignition switch 36 is connected to the relay assembly 28.
- a field winding 37 is supplied with a series winding 38 and a shunt winding 39, which are connected via brushes 40 and 42 and via the collector 44 of the motor, or directly to ground.
- the armature of the starter motor 12 is denoted by 46, its stator 48.
- FIG. 2 shows a circuit diagram of a single-stage energized starter in a conventional design.
- the positive pole 30 of the voltage source is connected on the one hand via the ignition start switch 36 and a connection 50 and on the other hand directly to an engagement relay 49.
- This comprises a holding winding 52 and a pull-in winding 54 which have the same winding sense, are wound on the same core and both are connected to the connection 50 with a winding end.
- the other winding end of the holding winding 52 is connected to the negative pole 31 and to ground
- the corresponding other winding end of the pull-in winding 54 is connected via the series winding 38 and the armature 46 of the starter motor 12 to the negative pole 31 and to ground.
- a shunt winding can be used in basically known manner 39 of the series winding 38 and the armature 46 of the starter motor are connected in parallel.
- the holding winding 52 and the pull-in winding 54 take in this known arrangement together the work of the meshing of the pinion 22 in the ring gear 26 on the engine and at the same time the function of switching the main current for the starter motor 12. In this case meets a tooth of the pinion 22 to a gap in the ring gear 26 so only a small force is necessary for meshing. If, during meshing, a tooth of the pinion 22 strikes a tooth of the ring gear 26, the meshing spring 32 shown in FIG. 1 is tensioned during meshing and the meshing operation is carried out with its support.
- FIG. 3 shows a circuit diagram according to the invention of a single-stage energized starter with which the initially described danger of damage to the toothing between the starter and the internal combustion engine is eliminated.
- Circuit arrangement corresponds in terms of construction with a Einspurrelais 49 and its connection to the DC network 30, 31 in principle, that in Figure 2, however, in this arrangement, the relay contact 56 at startup not full motor current but it is initially only the energization of the partial windings a and f the six partial windings a, b, c, d, e and f of the excitation winding 37.
- the stator of the starter motor 12 is six-pole, at startup, however, only pole pair energized with two diametrically opposite to the stator poles, while the remaining series winding part windings b, c, d and e are switched later.
- the starter is controlled via the ignition switch 36 and the terminal 50 and in this case the positive pole 30 of the
- the starter motor 12 reaches its full power for cranking the engine at a time when the pinion 22 in the ring gear 26th Fully meshed and the risk of damage is avoided.
- Figure 4 shows a circuit arrangement for two-stage energization of the starter motor 12. In place of the
- Einspurrelais 49 in Figure 3 enters a Einspurrelais 64 with a normally closed contact 66 and a normally open contact 68.
- the normally closed contact 66 with the pull-in winding 54 and the holding winding 52 are connected via a pilot relay 70, the connection point 50 and the ignition switch 36 with the positive pole 30 of the DC voltage source ,
- the second terminal of the holding winding 52 is grounded and the negative pole 31 of the DC voltage source, while the second terminal of the pull-in winding 54 is connected on the one hand via the starter motor 12 and on the other hand via the winding 58 of a switching relay 60 to ground and to the negative pole 31 of the DC voltage source.
- the winding 58 of the switching relay 60 is energized via the connection point 5Oq, whereby the relay moves in and closes the normally open contact 62 with a delay of approximately 20-80 ms from the start of the excitation and thus the next two partial windings b and e Energized energizing coil and thus increases the performance of the starter motor 12.
- the winding 76 is now also on the connection point 5Or a further switching relay 72 energized, so that this retracts and closes with a further delay of about 20-80 ms from the start of excitation of the winding 76 its working contact 74, via which the last two partial windings c and d of the excitation winding 37 are energized and thus the starter motor 12 has reached full capacity.
- the power increase is carried out here in three instead of two switching stages, and thus the mechanical load on the pinion gear connection to the internal combustion engine is made even more uniform.
- the pull-in coil 54 advantageously dampens the dynamics of the meshing movement and at the same time supplies a sufficiently high exciter current to the series-connected partial windings a-f of the starter motor 12 in order to slightly turn it and facilitate or enable the meshing process.
- a Einspurfeder additionally be used to assist the Einspurvorgangs.
- pilot control relay 70 The use of a pilot control relay 70 is for the
- the Einspurrelais 64 can also be energized analogous to the circuit arrangement in Figure 3 directly via the ignition switch.
- it lies Motor current in the first Bestromungsphase on the pull-in winding 54 in the order of up to 200 A, so that at least for high-performance starter motors in the first stage of energization, the use of a pilot control relay to bypass the Zündstartschalters 36 is appropriate.
- FIG. 5 shows a variant of the circuit arrangement according to FIG. 4, which differs from the previously described embodiment in that the excitation current for the
- Winding 37 from the beginning of the series connection current over four partial windings a, c, d and f is performed.
- the switching on of two additional partial windings b and e takes place again via the connection point 5Oq and the switching relay 60 with a delay of approximately 20-80 ms from the start of the excitation. It is therefore again a two-stage energization of the partial windings of the excitation winding 37 analogous to Figure 4, but already in the first switching operation four partial windings are energized.
- This is made possible, in particular, by the use of the pilot control relay 70, which relieves the ignition start switch 36 and allows the higher starting current to flow through the starter motor, provided that the mechanical load on the pinion and toothed ring connection during engagement is not excessively high.
- FIG. 6 shows a further circuit variant for the energization of the partial windings af of the exciter winding 37.
- an initial energization of four partial windings a, c, d and f of the exciter winding 37 takes place analogously to the embodiment according to FIG Partial windings b and e, however, does not take place in series with the armature 46 but in shunt across the switching relay 60, the winding 58 in the same manner as in the circuit arrangement according to FIG. 5 is supplied with current via the connection point 5Oq at the same time as the armature 46 and the partial windings of the exciter winding 37 energized in series connection.
- the inventive design of the starter for an internal combustion engine is particularly suitable for launch systems, which have the necessary space for one or two additional relays. In this case, the realization of the circuit arrangement with little additional effort is possible because the circuit can be performed with existing components and thereby the life of the starter can be extended.
- the inventive division of the excitation winding 37 is not limited to a six-pole version of the starter. It is preferably suitable for all pole numbers of the stator 48, in which the spatial position of the pole pairs does not deviate too much from a diameter orientation. This is especially true for stator designs with six, eight, ten or twelve poles.
