Definitions

  • this thrust motor comprising windings and a movable part.
  • the thrust motor is used to move a switching axis to electrically connect contacts and thus to close a circuit of a starter motor.
  • the movable part is also connected to a driver, which in turn interacts with an engagement lever for engaging a pinion.
  • a starting device with an engaging relay in which the movable part of the engaging relay is connected to a driver that is relatively movable to the movable part.
  • the engagement relay it can happen that the pinion rests on the face of the ring gear of the internal combustion engine and a contact device is switched on for switching on a starter motor of the starting device. A maximum current may flow through the contact device and thus through the starter motor, while the pinion is still in contact with the ring gear.
  • an engagement relay for an electrical machine and a method for operating an electrical machine, in particular designed as a starting device, with an engagement relay having the features of the independent patent claims are proposed.
  • the advantages of the invention of the engagement relay are that the proposed arrangement ensures that switching on the contact device of the engagement relay in order to switch on a starter motor of the starting device can only be closed when the pinion is at least partially engaged in the ring gear of the internal combustion engine. As a result, there is a risk that the pinion will jump over a tooth gap in the toothed ring and thereby the toothed ring or the pinion itself will no longer be damaged ("ratcheting"). By the gap or the associated stop of the stop part with the driver, the closing of the contact device is for Switching of the starter motor is prevented mechanically if the pinion is not at least partially meshed with the ring gear.
  • FIG 1 a view of a starting device 10 with part of an on-board network 13 is shown schematically. Furthermore, at the left end is the Figure 1 A toothed ring 15 of an internal combustion engine 17 is shown in detail.

  • the in Figure 1 The circuit shown shows the circuit or current path via which the electrical energy supply of the starting device 10 takes place.
  • the engagement relay 20 is connected to a positive pole of the power supply 27 via a so-called terminal 30.
  • the current then runs into the starter motor 23 via a so-called terminal 45.
  • a contact bridge 50 onto what is known as a plus bolt 51 and a minus bolt 52. Then, when the start switch 28 is closed, a current flows through the positive bolt 51, the contact bridge 50 and the negative bolt 52 into the starter motor 23 and drives it at full power.
  • two auxiliary contacts 53 and 54 are electrically conductively connected to one another by the contact bridge 50 or, alternatively, a similar contact. This leads to a pull-in winding 55 being energized.
  • this engagement relay 20 for actuating the contact bridge 50 has an apparatus, referred to here as a thrust motor 60 with the movable part 57, which, by energizing the pull-in winding 55 and also a holding winding 63, develops a force that enables the contact bridge 50 Via the movable part 57 - preferably designed as a magnet armature - to move against various resistances (springs for example).
  • FIG. 2 a more specific embodiment of the engagement relay 20 with the thrust motor 60 is shown in an initial position.
  • a contact device 65 is shown, to which, inter alia, the contact bridge 50, the plus bolt 51 and the minus bolt 52 belong.
  • this also includes an auxiliary contact 53 and an auxiliary contact 54.
  • these two auxiliary contacts 53, 54 serve to energize a pull-in winding 55 after the start switch 28 has been closed.
  • the contact bridge 50 is seated on a switching axis 67, which is passed through a magnetic yoke 70.
  • the contact bridge 50 is seated on an insulating sleeve 72.
  • the insulation sleeve 72 is inserted and guided in a cylindrical recess in the magnetic yoke 70.
  • a contact compression spring 73 is supported at its left end and thus at an end facing away from the contact bridge 50, on a shoulder of the switching axis 67, also not designated in detail from.
  • a stop element 75 rests on a pin 76 of reduced diameter.
  • the stop element 75 preferably designed as a simple perforated plate - rests with a surface which is directed towards the contact bridge 50 against a bottom 77 of a blind hole-like recess 78.
  • the blind hole-like recess 78 is made at one end 79 of the movable part 57. This end 79 faces away from the contact bridge 50.
  • the movable part 57 has - starting from the base 77 - a through opening 80 in the manner of a through hole.
  • the switching axis 67 is supported in this through opening 80 by means of a sliding bush 81.
  • a contact restoring spring 82 is supported on an end face of the sliding bush 81, which is not designated in detail and which is directed towards the contact bridge 50. At another end of the contact return spring 82, the latter is supported on the magnetic yoke 70.
  • a guide element 83 adjoins the end 79 of the movable part 57, which is preferably embodied here as a bushing, for example. This guide element 83 is fixed in place at its end facing the movable part 57.
  • a stop part 84 and a driver 85 are arranged in this guide element 83.
  • the stop part 84 and the driver 85 are held at a distance by a spring 86, which is designed here as a compression spring, for example, and by a force exerted by this spring 86.
  • the driver 85 is constructed as follows: from the side facing the movable part 57, a section 87 follows, which is particularly preferred and is designed here, for example, as a ring-like collar. This section 87 has an outer circumference with a radially outwardly directed surface 88. The driver 85 is guided in the guide element 83 with this radially outwardly directed surface 88. This enables the driver 85 to be guided precisely in the guide element 83 in the direction of an axis 89 which corresponds to a direction during switching and thus the movement of the contact bridge 50 and the movement of the movable part 57. In the direction facing away from the movable part 57, the driver 85 has a section 90 which is particularly preferably designed as an annular cylinder.
  • a preferably circular end face 91 At the end of the section 90 furthest away from the movable part 57 there is a preferably circular end face 91. Between this end face 91 and an end face of the stop element 75 there extends a return spring 92, which is particularly preferably designed as a compression spring. Between the end face 91 and a further end face 93 is a connecting section 94. In the direction facing away from the movable part 57, a slot 95 follows in the driver 85, which is particularly preferably designed as a longitudinal slot. A further end face 96 is located in the direction that is remote from the movable part 57, so that the slot 95 extends in the direction of the axis 89 between the two end faces 93 and 96.
  • the end face 96 is followed by an end section 97, which at this point preferably connects side parts of the slot 95, preferably in one piece.
  • the driver 85 thus includes, inter alia, the section 87 as a ring-like collar, the section 90, the connecting section 94, the side parts of the slot 95 and the end section 97.
  • the stop part 84 is particularly preferably constructed like a disk. It has a preferably disk-like pin part 98 which itself has an end face 99 directed in the direction of the axis 89 and at the same time towards the end face 96. Also directed in the direction of the axis 89 and, in this case, aligned with the end face 93, the pin part 98 has a further end face 100. the pin part 98 extends particularly preferably between the two end faces 99 and 100. The pin part 98 is guided at its end directed in the direction of the contact bridge 50 by means of a guide device 101 in the guide element 83 in such a way that the stop part 84 carries out a preferably exclusively axial movement, which runs in the direction of the axis 89.
  • the guide device 101 has two arms 102 extending from the pin part 98. Both arms 102 each have a guide section 103 which extends like a rod in the direction of the axis 89. These guide sections 103 have a surface 104 pointing away from the axis 89, ie radially outward from there, over which the stop part 84 is guided in the guide element 83 in such a way that this stop part 84 is movably guided in the direction of the axis 89 is.
  • a section of the engagement lever 22 engages in the installed state of the engagement relay 20. Due to a preferred installation position of the engagement relay 20 relative to a housing of the starting device 10, the driver 85 lifts the section 87 from a stop element 110 when the engagement lever 22 is inserted into the slot 95 (distance w not equal to zero).
  • FIG. 2 shows the rest position of the engagement relay 20
  • Figure 3 shows Figure 3 the engaging relay 20 shortly after the engaging relay 20 is switched on with an already slightly changed position of the movable part 57.
  • the stop element 75 with its surface facing the contact bridge 50 is already slightly lifted from the surface or the bottom 77 of the movable part 57. Accordingly, there is a distance d between the stop element 75 and the floor 77.
  • the situation shown in this figure is intended to show a situation of the mechanics in the engaging relay 20 or in the starter or the starting device 10, in which all so-called backlashes, ie axial play in the starting device 10 or the engaging relay, up to the imminent shifting of the pinion 25 20 are used up.
  • Such slack can be or are, for example, distances between the end face 99 and an upper end of the engagement lever 22. Furthermore, slacks that can act between the engagement lever 22 and a pinion shaft 106 are also possible. In this situation, a gap s between the end faces 100 and 93 is preferably still of the size that is also shown during the rest position Figure 2 present. A distance a still corresponds to a distance between the ring gear 15 and the pinion 25 in the idle state. A distance k which exists between a contact bridge 50 and the auxiliary contacts 53, 54 is still zero here. This means that the pull-in winding 55 is energized.
  • the engagement relay 20 for an electrical machine which is preferably used as a starting device 10 for engaging a pinion 25, is thus disclosed.
  • the engagement relay 20 has a contact device 65 for connecting electrical contacts 120, 121.
  • the electrical contact 120 is connected in particular to a plus bolt 51 and the electrical contact 121 in particular to a minus bolt 52.
  • the engagement relay has a thrust motor 60 which is used to move the switching axis 67.
  • the thrust motor 60 has a movable part 57, which is preferably designed as a magnet armature. Accordingly, the thrust motor 60 is designed, for example, as a so-called lifting magnet.
  • the movable part 57 serves to actuate the switching axis 67.
  • the movable part 57 is connected to a driver 85.
  • a stop part 84 is movable relative to the movable part 57 of the thrust motor 60, and when the engagement relay 20 is in a state of rest there is a gap s between the stop part 84 and the driver 85.
  • a spring 86 holds the stop member 84 and the driver 85 at a distance.
  • a compression spring is arranged between the stop part 84 and the driver 85. This means that it is provided in particular that the spring 86 is designed as a compression spring.
  • the stop part 84 and the driver 85 are guided against one another. In particular, it is provided that the stop part 84 and the driver 85 are guided directly against one another.
  • the peg part 98 is designed in particular in the manner of a plate and can therefore be guided easily in the slot 95 with the plate-like surfaces of the peg part 98. This means that the stop part 84 seated in the slot 95 cannot be rotated about the axis 89. A small torsional backlash is only possible, particularly preferably, in order to prevent an undesired blockage between the two parts.
  • a pin part 98 which is designed in particular in the manner of a plate, engages in a slot 95 of the driver 85 and, as a result, the stop part 84 and the driver 85 are guided against one another.
  • the stop part 84 has a radially outwardly directed surface 104, the stop part 84 being guided in the guide element 83 by means of this surface 104.
  • the component driver 85 interacting with the stop part 84 has a section 87, in particular designed as a ring-like collar, which has a radially outwardly directed surface 88, the driver 85 being guided with this surface 88 in the guide element 83.
  • the driver 85 has a collar-like section 87 and the switching axis 67 has a stop element 75, in particular at its end facing the driver 85, in particular carries it.
  • a further stop element 110 is arranged between the collar-like section 87 and the stop element 75, which in the idle state, in particular the non-installed engagement relay 20, is a stop for the collar-like section 87 and in the switching state a stop for the further stop element 75 , in particular the switching axis 67.
  • the further stop element 110 is held between the guide element 83, in particular a collar 125, of the guide element 83 designed as a bushing, and an end face 128 of the movable part 57.
  • a starting device 10 with an engaging relay 20 according to one of the embodiment variants described above is provided.
  • Figure 4 shows the engagement relay 20 in the starting device 10 in a situation in which a distance a between the pinion 25 and the ring gear 15 is now zero.
  • the distances s and k are preferably unchanged, ie the distance for k is as already in FIG Figure 3 in principle zero, since the contact bridge 50 is in contact with the auxiliary contacts 53, 54.
  • the representations of the distance k are in Figure 3 and Figure 4 symbolic.
  • a pinion 25 is designed as a so-called plug-in pinion, as is the case in the exemplary embodiment, but not necessarily the case, there is a further distance m, which denotes a so-called plug-in pinion path.
  • the pull-in winding 55 is energized. Since the starter motor 23 is arranged in the current path of the pull-in winding 55 and the current is so large that the starter motor 23 rotates, ultimately a pinion 25 also rotates. Furthermore, this means that the stop element 110 according to the illustration Figure 6 presses on the stop element 75. The distance d has therefore now reached its maximum. Furthermore, the distance or gap s between the two end faces 93, 100 has now decreased. In the course of the increase in the distance w or, if applicable, the emergence of the distance w, a gap or distance k not equal to zero is now also established.
  • the gap s is now also compared to the previous states, which in the Figures 2 to 5 shown reduced in size.
  • the driver 85 compared with the situation according to Figure 5 , its position has not changed, since the distances a and m have not changed, and the end section 97 with its end face 96 rests unchanged against the upper end of the engagement lever 22.
  • a method for operating an electrical machine, in particular designed as a starter device 10, with an electrical starter motor 23 and with an engagement relay 20, wherein after the engagement relay 20 is switched on, a contact device 65 is to be actuated and a switch of the circuit of the starter motor 23 is thereby closed is, wherein a movable part 57 of a thrust motor 60 of the engaging relay '20 is connected to a driver 85 and by an engagement movement of the movable part 57 of the driver 85 on an engaging lever 22 causes an engaging force to engage a pinion 25 in a ring gear 15, wherein A stop part 84 is arranged between the movable part 57 of the thrust motor 60 and the driver 85, initially with a gap s with an initial size between the driver 85 and the stop part 84 and when moving the movable part 57 of the thrust motor 60 when switching the gap s we downsized d.
  • the gap s is reduced.
  • the movable part 57 of the thrust motor 60 is prevented from moving further and, as a result, further movement of the switching axis 67 and thereby closing of the contact device 65 is initially stopped.
  • FIG 7 a further state of the engagement relay 20 or the starting device 10 is shown.
  • This state follows the state shown in Figure 6 is shown.
  • the distances a and m are still zero.
  • the distance k increases, in other words, the distance between the contact bridge 50 and the contact surface of the positive pin 51 or the contact surface of the negative pin 52 becomes smaller.
  • the gap s is now also zero, ie the distance between the stop part 84 and the driver 85 cannot be reduced any further.
  • the distance v can accordingly no longer be increased in this situation either. This also applies to the distance w.
  • a stop element 75 arranged on the switching axis 67 is placed against the stop element 110 on the movable part 57 of the thrust motor 60. Before or after the stop element 75 arranged on the switching axis 67 is applied to the stop element 110 on the movable part 57 of the thrust motor 60, the driver 85 is removed from the stop element 110 on the movable part 57 of the thrust motor 60, and thereby a spring force of the spring 86 between the stop part 84 and the driver 85 enlarged.
  • a so-called “blind circuit” of the starting device 10 occurs, ie the start switch 28 has been actuated (starting device 10 switched on), but the pinion 25 cannot mesh with the ring gear 15. Accordingly, in this situation it is necessary to switch off the starting device 10 so that a holding winding 115 is switched off and does not overheat.
  • Such a shutdown can either be done manually by the vehicle driver (manual opening of the Start switch 28) or by a control device, not shown here or shown in more detail, which detects this situation (no engagement of the pinion 25 in the ring gear 15 possible) and then automatically, e.g. B. after the lapse of time, temperature of a winding, such as a holding winding 115, the circuit to the starting device 10 opens.
  • the movement of the movable part 57 enables the stop element 110 to move forward, so that a force continues to act on the stop element 75 and consequently also on the switching axis 67 in the direction of the contact bridge 50.
  • the contact bridge 50 will touch the contact surface of the positive bolt 51 and the negative bolt 52 and thereby close the main current path of the starter motor 23.
  • the movable part 57 of the thrust motor 60 is thus moved and the switch of the circuit of the starter motor 23 is thereby closed.
  • the starter motor 23 will then drive the pinion 25 with maximum power and the internal combustion engine 17 can be started.

Procédé pour faire fonctionner une machine électrique en particulier formée comme un dispositif de démarrage (10) ayant un moteur de démarreur électrique (23) et un relais d'engrènement (20), dans lequel après la mise en marche du relais d'engrènement (20), un dispositif de contact (65) est actionné, en fermant ainsi un commutateur du circuit du moteur de démarreur (23), dans lequel une pièce mobile (57) d'un moteur de poussée (60) du relais d'engrènement (20) est reliée à une coulisse (85) et un mouvement d'actionnement de la pièce mobile (57) de la coulisse (85) crée une force d'engrènement sur une fourchette d'engrènement (22) afin d'engrener un pignon (25) dans une couronne dentée (15),
    dans lequel une pièce de butée (84) est mobile par rapport à la pièce mobile (57) du moteur de poussée (60),
    dans lequel il existe tout d'abord un espace (s) ayant une taille initiale entre la coulisse (85) et la pièce de butée (84) et pendant le mouvement de la pièce mobile (57) du moteur de poussée (60), l'espace (s) est réduit pendant la commutation,
    caractérisé en ce qu'une pièce de pivot (98) de la pièce de butée (84) s'engage dans une fente (95) de la coulisse (85), dans lequel la fente (95) s'étend entre deux surfaces frontales (93, 96) de la fente (95), la pièce de butée (84) et la coulisse (85) étant ainsi guidées l'une par rapport à l'autre.
  7. Procédé selon la revendication 6, caractérisé en ce qu'un enroulement d'appel (55) du moteur de poussée (60) est alimenté en courant, dans lequel l'alimentation en courant de l'enroulement d'appel (55) alimente en particulier le moteur de démarreur (23) monté en série avec cet enroulement d'appel (55), en mettant ainsi le pignon (25) en rotation.
  8. Procédé selon la revendication 6 ou 7, caractérisé en ce que pendant le mouvement de la pièce mobile (57) du moteur de poussée (60), un axe de commutation (67) est déplacé pendant la commutation, dans lequel un commutateur (56) initialement fermé est ouvert pour alimenter un enroulement d'appel (55) en courant, et en ce que l'espace (s) est réduit à l'encontre d'une force élastique d'un ressort (86) entre la pièce de butée (84) et la coulisse (85).
  9. Procédé selon la revendication 8, caractérisé en ce que pendant le mouvement de la pièce mobile (57) du moteur de poussée (60) pour la commutation, l'espace (s) est réduit de sorte que la coulisse (84) vient en butée contre la pièce de butée (84).
  10. Procédé selon la revendication 8 ou 9, caractérisé en ce que le pignon (25) vient en butée avec l'une de ses dents contre l'une des dents de la couronne dentée (15) et l'espace (s) se réduit ensuite.
  11. Procédé selon la revendication 10, caractérisé en ce que la mise en butée du pignon (25) contre la couronne dentée (15) empêche un mouvement supplémentaire de la pièce mobile (57) du moteur de poussée (60) et ainsi un mouvement supplémentaire de l'axe de commutation (67), en arrêtant ainsi initialement une fermeture du dispositif de contact (65).
  12. Procédé selon la revendication 11, caractérisé en ce qu'un élément de butée (75) agencé sur l'axe de commutation (67) d'un élément de butée (75) est appliqué sur la pièce mobile (57) du moteur de poussée (60).
  13. Procédé selon la revendication 12, caractérisé en ce qu'avant ou après l'application de l'élément de butée (75) agencé sur l'axe de commutation (67) sur l'élément de butée (110) de la pièce mobile (57) du moteur de poussée (60), la coulisse (85) s'éloigne de l'élément de butée (110) de la pièce mobile (57) du moteur de poussée (60), en augmentant ainsi une force élastique du ressort (86) entre la pièce de butée (84) et la coulisse (85).
  14. Procédé selon la revendication 12 ou 13, caractérisé en ce qu'une dent du pignon rotatif (25) commence par s'engrener entre deux dents de la couronne dentée (25).
  15. Procédé selon la revendication 14, caractérisé en ce que la pièce mobile (57) du moteur de poussée (60) avance, en fermant ainsi le commutateur du circuit du moteur de démarreur (23).
