Definitions
- Engagement relay for and method for operating a preferably designed as a starting device electrical machine with an engagement relay
- the advantages of the invention of the engagement relay are that it is achieved by the proposed arrangement that turning on the contact means of the contactor to turn on a starter motor of the starting device, compelling can only be closed when the pinion at least partially meshes in the ring gear of the internal combustion engine is. This is a risk that the pinion skips a tooth gap in the ring gear and thereby the ring gear or the pinion itself is damaged ("ratcheting") no longer given ..
- FIG. 1 shows a schematic view of a starting device with an engagement relay, connected in a vehicle electrical system of a motor vehicle
- Figure 2 shows an engagement relay in a longitudinal section
- Figures 3 to 7 show at least partially cut the relay in longitudinal section to different motion situations.
- FIG. 1 schematically shows a view of a starting device 10 with a part of a vehicle electrical system 13. Furthermore, a toothed rim 15 of an internal combustion engine 17 is shown in detail at the left end of FIG.
- the starting device 10 has an engagement relay 20, an engagement lever 22, a starter motor 23 and further and, among other things, a pinion 25.
- the illustrated in Figure 1 part of the electrical system shows a typically referred to as a starter battery power supply 27 and a start switch 28.
- Der shown in Figure 1 circuit shows the circuit or current path through which the electrical power supply of the starting device 10 takes place.
- the engagement relay 20 is connected via a so-called terminal 30 with a positive pole of the power supply 27. Via a so-called terminal 45, the current then flows into the starter motor 23.
- a contact bridge 50 on a so-called plus pin 51 and a minus pin 52 moves. Then, when the start switch 28 is closed, a current flows via the plus pin 51, the contact bridge 50 and the minus pin 52 into the starter motor 23 and drives it at full power. With the switching on of the start switch 28 while still before activation or movement of the contact bridge 50, two auxiliary contacts 53 and 54 are interconnected electrically lei tend through the contact bridge 50 or alternatively a similar contact. This results in that a pull-in winding 55 is energized.
- this engagement relay 20 for actuating the contact bridge 50 has a here called thrust motor 60 apparatus with the movable part 57 which develops by energizing the pull-in winding 55 and a holding winding 63, a force that allows the contact bridge 50 via the movable part 57 - preferably leads out as a magnet armature - against different resistors (springs, for example) to move.
- FIG. 2 shows a more concrete embodiment of the engagement relay 20 is shown with the thrust motor 60 in an initial position.
- a contact device 65 is shown, to which inter alia the contact bridge 50, the plus pin 51 and the minus pin 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 closing the start switch 28.
- 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 insulating sleeve 72 is inserted and guided in a cylindrical recess in the magnetic yoke 70.
- a contact pressure spring 73 is supported at its left end and thus at one end, which faces away from the contact bridge 50, at a likewise unspecified shoulder of the switching axis 67th from.
- end 74 of the switching axis 67 sits a stop element 75 on a reduced diameter pin 76.
- the stop element 75 - preferably designed as a simple perforated plate - is located with a surface which is directed to the contact bridge 50 at a bottom 77 of a blind hole-like recess 78 at.
- the blind hole-like recess 78 is introduced at one end 79 of the movable part 57. This end 79 is remote from the contact bridge 50.
- the movable part 57 has - starting from the bottom 77 - a through hole 80 in the manner of a through hole.
- the switching axis 67 is mounted by means of a slide bush 81.
- a contact restoring spring 82 is supported at a unspecified end face of the sliding bushing 81, which is directed to the contact bridge 50.
- a contact restoring spring 82 is supported at another end of the contact return spring 82, this is supported on the magnetic yoke 70 from.
- a guide member 83 connects to which is preferred and here exemplified as a socket.
- This guide element 83 is fixedly secured at its end directed towards the movable part 57.
- a stop member 84 and a driver 85 are arranged in this guide element 83.
- the stop member 84 and the driver 85 are held by a spring 86, which is exemplified here as a compression spring, and by a force exerted by this spring 86 force at a distance.
- the driver 85 is constructed as follows: from the side which faces the movable part 57, initially follows a section 87, which is particularly preferred and here exemplified as a ring-like collar. This section 87 has an outer periphery with a radially outwardly directed surface 88. With this radially outwardly directed surface 88 of the driver 85 is guided in the guide member 83. Thereby, a precise guidance of the driver 85 in the guide member 83 in the direction of an axis 89 is possible, which corresponds to a direction when switching and thus the movement of the contact bridge 50 and the movement of the movable member 57.
- the driver 85 has in a direction away from the movable part 57 a portion 90 which is particularly preferably designed annular cylindrical.
- a preferably circular end face 91 At the end of the portion 90 farthest from the movable part 57, there is a preferably circular end face 91. Between this end face 91 and an end face of the stopper member 75 there extends a return spring 92, which is particularly preferred as a compression spring. Between the end face 91 and a further end face 93 is a connecting portion 94. In the direction facing away from the movable part 57, in the driver 85, a slot 95 connects, which is particularly preferably designed as a longitudinal slot. In the direction away from the movable part 57, there is another end face 96, 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 portion 97, which at this point preferably integrally connects side parts of the slot 95.
- the driver 85 thus comprises 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 member 84 is particularly preferably constructed like a disk. It has a preferably disk-like pin member 98, which in the direction of the axis 89 and thereby directed to the end face 96 itself has an end face 99. Also directed in the direction of the axis 89 and aligned in this case to the end face 93, the pin member 98 has a further end face 100. D. h. the pin member 98 extends particularly preferably between the two end faces 99 and 100. The pin member 98 is guided in its direction towards the contact bridge 50 end by means of a guide device 101 in the guide member 83 such that the stop member 84 performs a preferably exclusively axial movement, which extends in the direction of the axis 89.
- the guide device 101 has two outgoing from the pin member 98 arms 102. Both arms 102 each have a guide portion 103 which extends rod-like in the direction of the axis 89. These guide portions 103 have a surface 89 pointing away from the axis 89, ie radially outwardly directed surface 104, over which the stop member 84 is guided in the guide member 83 so that this stop member 84 in the direction of the axis 89 movable and guided is. In the slot 95, ie between the end faces 96 and 99, a portion of the engagement lever 22 engages in the installed state of the engagement relay 20.
- the driver 85 lifts the portion 87 of 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
- FIG. 3 shows the engagement relay 20 shortly after switching on the engagement relay 20 with an already slightly changed position of the movable part 57.
- the stop element is shown in FIG 75 with its directed to the contact bridge 50 surface of the surface or the bottom 77 of the movable member 57 is already slightly lifted. Accordingly, there is a distance d between the stopper 75 and the bottom 77.
- the situation shown in this figure is intended to show a situation of the mechanism in the engagement relay 20 or in the starter or the starter 10, in the imminent shifting of the pinion 25 all so-called lots, ie axial play in the starter 10 and the engagement relay 20, are used up.
- lots may be or are, for example, distances between the end face 99 and an upper end of the engagement lever 22.
- a gap s between the end faces 100 and 93 is preferably still in the size which is also present during the rest position according to FIG.
- a distance a still corresponds to a distance between sprocket 15 and pinion 25 in the idle state.
- a distance k which is present 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 electric machine, which preferably serves as a starting device 10 for engaging a pinion 25, disclosed.
- the engagement relay 20 has a contact device 65 for connecting electrical contacts 120, 121.
- the electrical contact 120 is in particular connected to a plus pin 51 and the electrical contact 121 in particular to a minus pin 52.
- the engagement relay has a thrust motor 60, which serves 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 solenoid.
- the movable part 57 serves to actuate the switching axis 67.
- the movable part 57 is connected to a driver 85.
- a stop member 84 is movable relative to the movable member 57 of the thrust motor 60 and in a resting state of the engagement relay 20 is between the stop member 84 and the driver 85, a gap s.
- a spring 86 holds the stopper 84 and the driver 85 at a distance.
- a compression spring is arranged between the stop member 84 and the driver 85. D. h., That is provided in particular that the spring 86 is formed as a compression spring.
- the stop member 84 and the driver 85 are guided against each other. In particular, it is provided that the stop member 84 and the driver 85 are guided directly against each other.
- the guide against each other of the stop member 84 and the driver 85 is thereby possible that in the slot 95 of the driver 85, the stop member 84 is guided with the pin member 98.
- the pin member 98 is formed in particular plate-like and is thus well guided with the plate-like surfaces of the pin member 98 in the slot 95. That is, the stopper member 84 is seated in the slot 95 is almost not rotatable about the axis 89. It is only particularly preferred a small torsional play possible to prevent unwanted blockage between the two parts. Accordingly, it is provided that a pin member 98, which is in particular plate-like, engages in a slot 95 of the driver 85 and thereby the stop member 84 and the driver 85 are guided against each other.
- the stop member 84 has a radially outwardly directed surface 104, wherein the stop member 84 is guided by means of this surface 104 in the guide member 83.
- the interacting with the stop member 84 component driver 85 has a, in particular formed as an annular collar portion 87 which has a radially outwardly directed surface 88, wherein the driver 85 is guided with this surface 88 in the guide member 83. It is provided in particular that the driver 85 has a collar-like portion 87 and the switching axis 67 has a stop element 75, in particular at its end directed to the driver 85, in particular carries.
- a further stop element 110 is arranged, which in the idle state, in particular the non-installed contactor 20, a stop for the collar-like portion 87 and in the switching state, a stop for the further stop element 75th , in particular the switching axis 67 is. Furthermore, it is provided that 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 bush, and an end face 128 of the movable part 57. There is further provided a starting device 10 with an engagement relay 20 according to one of the above-described embodiments.
- 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 unchanged, ie for k is the distance, as already in 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 in Figure 3 and Figure 4 are symbolic.
- a pinion 25 is designed as a so-called plug-in pinion, as in the exemplary embodiment, but not necessarily the case, there is still a further distance m, which designates a so-called Steckritzelweg.
- the pull-in winding 55 is energized after switching on the start switch 28. 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 also a pinion 25 rotates. Furthermore, this means that the stop element 110 according to the illustration of Figure 6 on the stop element 75 presses. Accordingly, the distance d has now reached its maximum. Furthermore, the distance or gap s between the two end faces 93, 100 has now decreased. In the course of increasing the distance w or possibly the emergence of the distance w, now also a gap or distance k is set equal to zero.
- the gap s is reduced.
- the movable part 57 of the thrust motor 60 is prevented from further movement, thereby stopping further movement of the switching axis 67 and thereby closing the contact device 65 first.
- FIG. 7 shows a further state of the engagement relay 20 or the starting device 10. This condition follows the condition shown in FIG. The distances a and m are still zero. Be further absorbed by Be drawn in the moving part 57 at meanwhile constant distance d, the distance k increases, in other words, the distance between the contact bridge 50 and the contact surface of the plus pin 51 and the contact surface of the minus pin 52 is smaller. As shown, now also the gap s is zero, ie the distance between the stop member 84 and the driver 85 is not further reduced. The distance v is accordingly no longer be enlarged in this situation. This also applies to the distance w.
- a arranged on the switching axis 67 stop member 75 is thereby applied to the stop member 110 on the movable part 57 of the thrust motor 60.
- the driver 85 Before or after the application of arranged on the switching axis 67 stop member 75 on the stop member 110 on the movable part 57 of the thrust motor 60 of 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 stopper 84 and the driver 85 increases.
- the situation shown in Figure 7 is maintained as long as the tooth-on-tooth position between the pinion 25 and the ring gear 15 is maintained.
- the starter motor 23 is energized by the flow of current through the pull-in winding 55 at the beginning of the process because the pull-in winding 55 is connected in series with the starter motor 23. If the starter motor 23 is energized so strongly that it rotates sufficiently strong even after interrupting the power supply of the pull-in winding 55 (inertia), then it is possible that the pinion 25 is actually rotated by this drive so far that a tooth Gap situation between pinion 25 and ring gear 15 sets.
