Description
Kontaktgeber für elektromagnetisch schaltbare Zahnräderwechselgetriebe, insbesondere für Kraftfahrzeuge Die Erfindung betrifft einen Kontaktgeber für elektromagnetisch schaltbare Zahnräderwechselgetriebe, insbesondere für Kraftfahrzeuge, mit einer um die Kanten einer quadratischen Auflagefläche kippbaren Kontaktplatte, .durch die beim Kippen der Kontakt für den zugeordneten Gang .geschlossen wird.Contactor for electromagnetically switchable gear change gears, in particular for motor vehicles The invention relates to a contactor for electromagnetic switchable gear change transmission, in particular for motor vehicles, with a contact plate tiltable around the edges of a square support surface which is closed when the contact for the assigned gear is tilted.
Im Kraftfahrzeugbau sind unter anderem zwei Schaltsysteme bei -der Verwendung elektromagnetisch geschalteter Wechselgetriebe bekannt.In automotive engineering, there are two switching systems in -the Use of electromagnetically switched change gears known.
Es handelt sich einmal um das Vorwählsystem, bei welchem durch einen Vorwählschalter der gewünschte Gang vorgewählt wird, ohne daß die Vorwählung einen Schaltvorgang auslöst. Beim Betätigen der Kupplung wird dann der Stromkreis geschlossen und der Schaltvorgang vollzogen.It concerns the preselection system, in which by a Selector switch the desired gear is preselected without preselecting one Switching process triggers. When the clutch is operated, the circuit is then closed and the switching process is completed.
Bei dem anderen Schaltsystem wird beim Betätigen der elektrischen Schaltung zunächst automatisch ausgekuppelt, und an den Entkupplungsvorgang schließt sich selbsttätig der Schaltvorgang an.In the other switching system, when the electrical The gearshift is initially automatically disengaged, and the disengagement process closes the switching process starts automatically.
Im ersten Fall ist ein Kontaktgeber erforderlich, dessen Kontakte dauernd geschlossen bleiben (Dauerkontaktgabe), damit die Stromkreise für den einzuschaltenden, vorgewählten Gang vorbereitet sind. Im zweiten Fall ist ein Kontaktgeber erforderlich, bei welchem die Kontakte nur so lange geschlossen bleiben, als der Schalthebel angedrückt ist (Tippkontaktgabe), damit die Schaltspulen nicht unnötig lange unter Strom stehen.In the first case, a contactor is required, its contacts remain permanently closed (permanent contact) so that the circuits for the to be switched on, selected gear are prepared. In the second case, a contactor is required, in which the contacts remain closed only as long as the switch lever is pressed is (tapping contact) so that the switching coils are not energized for an unnecessarily long time.
Aufgabe der Erfindung ist es, für beide unterschiedlichen Arten des Kontaktgebers möglichst einheitliche Konstruktionsteile zu erreichen und das Prinzip auf eine einfache Art zu verwirklichen.The object of the invention is for both different types of Contactor to achieve construction parts that are as uniform as possible and the principle in a simple way.
Es ist ein Kontaktgeber bekannt, bei dem eine Kontaktplatte um die Kanten einer quadratischen Auflage geschwenkt wird, wobei je nach Schwenkrichtung der Stromkreis für einen bestimmten Gang geschlossen wird. Dieser Kontaktgeber ist jedoch nur als Tippschalter zu verwenden, wobei für jeden Gang ein eigener, auf die Kontaktplatte außerhalb der als Unterstützungsfläche dienenden quadratischen Auflage einwirkender Druckknopf zum Schwenken der Kontaktplatte vorgesehen ist, und hat den Nachteil, daß eine Ganganzeige fehlt. Sobald dieser Schalter losgelassen wird, kann der Fahrer nicht mehr sehen, welcher Gang geschaltet ist.There is a contactor known in which a contact plate around the Edges of a square support is pivoted, depending on the pivot direction the circuit for a specific gear is closed. This contactor is but only to be used as a tip switch, with a separate one for each gear the contact plate outside the square serving as a support surface Support acting push button is provided for pivoting the contact plate, and has the disadvantage that a gear indicator is missing. As soon as this switch is released the driver can no longer see which gear is engaged.
Weiter sind Kontaktgeber bekannt, bei welchen sich der Schalthebel in einer Kugelpfanne bewegt und das andere Ende des Schalthebels in einer Kulisse geführt ist. Jeweils in denEndstellungen wird mit demSchalthebel direkt Kontakt gegeben, oder es werden Kontaktfedern zusammengedrückt.Contactors are also known in which the shift lever moves in a ball socket and the other end of the shift lever in a setting is led. In each of the end positions there is direct contact with the shift lever given, or contact springs are compressed.
Die Erfindung besteht darin, daß die Kontaktplatte mittels eines in mehreren Ebenen schwenkbaren Schalthebels über einen gefederten, am Schalthebel angeordneten Druckbolzen kippbar ist, wobei der Schalthebel zur Ganganzeige in der Schaltstellung oder annähernd in der Schaltstellung verbleibt.The invention consists in that the contact plate by means of an in several levels of swiveling shift lever via a spring-loaded, on the shift lever arranged push pin is tiltable, the shift lever for gear display in the Switch position or remains approximately in the switch position.
In der Zeichnung sind zwei Ausführungsbeispiele der Erfindung dargestellt. Es zeigt Abb. 1 den Kontaktgeber von unten .gesehen, Abb. 2 einen Längsschnitt durch den Kontaktgeber bei einer Ganganzeigestellung des Schalthebels, Abb. 3 die Draufsicht bei abgenommenem Gehäusedeckel mit Blick auf die Kontaktplatte, Abb. 4 einen Längsschnitt durch den Kontaktgeber in Mittelstellung des Schalthebels und Abb. 5 einen auszugsweisen Längsschnitt durch den Kontaktgeber in Kontaktstellung für Dauerkontakt. Das erste Ausführungsbeispiel nach Abb.2 und 4 betrifft einen Kontaktgeber für Tippkontaktgabe, während das zweite Ausführungsbeispiel nach Abb. 5 auf einen abgewandelten Kontaktgeber für Dauerkontaktgabe gerichtet ist, wie er bei Vorwählschalteinrichtungen notwendig ist.Two exemplary embodiments of the invention are shown in the drawing. Fig. 1 shows the contactor from below. Fig. 2 shows a longitudinal section through the contactor in a gear indicator position of the shift lever, Fig. 3 the top view with the housing cover removed, looking at the contact plate, Fig. 4, a longitudinal section by the contactor in the middle position of the shift lever and Fig. 5 an excerpt Longitudinal section through the contactor in the contact position for permanent contact. The first The embodiment according to Figures 2 and 4 relates to a contactor for tapping contact, while the second embodiment of Fig. 5 on a modified contactor is directed for permanent contact, as is necessary with preselector switching devices is.
Für die Verwendung des Kontaktgebers zur Direktschaltung, bei welcher bei Betätigung des Schalthebels zunächst die Kupplung gelöst und anschließend der Schaltvorgang selbsttätig vollzogen wird, ist es notwendig, alle Gänge alsTippkontakte auszubilden, d. h., beim Loslassen des Schalthebels muß der Stromkreis wieder unterbrochen werden. Der Schalthebel soll jedoch zum Zwecke der Ganganzeige in der geschalteten Stellung verbleiben.For the use of the contactor for direct switching, in which When the shift lever is operated, the clutch is first released and then the Switching process is carried out automatically, it is necessary to use all gears as tip contacts to train, d. In other words, when you let go of the shift lever, the circuit must be interrupted again will. However, the gearshift lever should be switched on for the purpose of showing the gear Remain in position.
Aus Abb. 2 ist zu ersehen, daß der Schalthebel 1 in einer Kugelkalotte 2 im Gehäusedeckel 3 nach allen Seiten schwenkbar gelagert ist. In einer Axialbohrung am unteren Ende des Schalthebels 1 befindet sich ein in der Längsrichtung des Schalthebels 1 verschiebbarer Druckbolzen 4, der durch eine Feder 5 zwischen dem Schalthebel 1 und dem Druckbolzen 4 eine schwenkbare Kontaktplatte 6 an eine quadratische Fläche 7 drückt, wobei das eine Ende des Druckbolzens 4 in einer beim allgemein gebräuchlichen Vierganggetriebe quadratischen Tasche 6ca der Kontaktplatte 6 aufliegt, innerhalb welcher er begrenzt allseitig beweglich ist.From Fig. 2 it can be seen that the shift lever 1 in a spherical cap 2 is pivotally mounted in the housing cover 3 in all directions. In an axial bore at the lower end of the shift lever 1 is a in the longitudinal direction of the shift lever 1 displaceable pressure pin 4, which by a spring 5 between to the Shift lever 1 and the pressure pin 4 a pivotable contact plate 6 on a square Surface 7 presses, one end of the pressure pin 4 in a general Usual four-speed gear square pocket 6ca of the contact plate 6 rests, within which it can be moved to a limited extent on all sides.
Innerhalb des Gehäusedeckels 3 ist am Schalthebel 1 ein Bund 8 vorgesehen. Wenn der Schalthebel 1 über seine in Abb.2 gezeigte Ganganzeigestellung ohne Kontaktgabe hinaus in die Schaltstellung gedrückt wird, so steht der Bund 8 am Gehäusedeckel 3 an und verhindert zunächst, daß die Kontaktplatte 6 um die Kante der quadratischen Auflagefläche genügend weit gekippt werden kann, um Kontakt zu geben. Erst beim weiteren Andrücken in die Schaltrichtung schwenkt der Schalthebel 1 um den Berührungspunkt des Bundes 8 am Gehäusedeckel 3, wobei sich die Kugel aus dem Gehäusedeckel 3 abhebt und die Feder 5 zusätzlich zusammengedrückt wird, was die Berührung der Schaltkontakte ermöglicht.A collar 8 is provided on the shift lever 1 inside the housing cover 3. If the shift lever 1 is beyond its gear display position shown in Fig is also pressed into the switching position, the collar 8 is on the housing cover 3 and prevents first that the contact plate 6 around the edge of the square Support surface can be tilted enough to make contact. Only when further pressure in the switching direction, the switching lever 1 pivots around the point of contact of the federal government 8 on the housing cover 3, wherein the ball lifts out of the housing cover 3 and the spring 5 is additionally compressed, causing the contact of the switch contacts enables.
Wird der Schalthebel 1 wieder losgelassen, so entspannt sich die Feder 5 so lange, bis die Kugelfläche des Schalthebels 1 in der Kalotte 2 des Gehäusedekkels 3 anliegt.If the shift lever 1 is released again, the spring relaxes 5 until the spherical surface of the shift lever 1 in the spherical cap 2 of the housing cover 3 is present.
Das Drehmoment, hervorgerufen durch den federbelasteten Druckbolzen 4 und den Hebelarm der Kippkante, sowie das Gegenmoment, hervorgerufen durch den Hebelarm des Anlagepunktes am Gehäusedeckel 3 und den Gegendruck der Feder 5, sind dann in Gleichgewicht.The torque caused by the spring-loaded pressure bolt 4 and the lever arm of the tilting edge, as well as the counter torque caused by the Lever arm of the contact point on the housing cover 3 and the counter pressure of the spring 5 are then in equilibrium.
Die Kontaktplatte 6 hebt sich wieder von der Kontaktstellung ab. Der Schalthebel 1 verbleibt jedoch annähernd in der geschalteten Stellung und dient als Ganganzeige.The contact plate 6 is raised again from the contact position. Of the Shift lever 1, however, remains approximately in the shifted position and is used as a gear indicator.
Durch diese -Maßnahme ist es möglich, alle Kontakte der Gangschaltung alsTippkontakte auszubilden, ohne zusätzliche Federn für den Abhub der Kontaktplatte 6 vorsehen zu müssen.With this measure it is possible to use all contacts of the gear shift to be designed as tip contacts without additional springs for lifting the contact plate 6 to have to provide.
In Abb. 4 ist ersichtlich, daß bei Mittelstellung des Schalthebels 1 der verschiebbare Druckbolzen 4 gegen die Wirkung einer Feder 9 auf einen Kontakt 10 drückt, der mit dem Gegenkontakt 11 den Stromkreis für die Leerlaufbetätigung schließt.In Fig. 4 it can be seen that in the middle position of the shift lever 1 the displaceable pressure pin 4 against the action of a spring 9 on a contact 10 pushes, which with the mating contact 11, the circuit for the idle actuation closes.
Der Stromkreis für den Rückwärtsgang wird mit dem Druckknopf 12 über den Kontakt 13 geschlossen. Soll das Wechselgetriebe mit Vorwählung geschaltet werden, so muß der Kontaktgeber nach dem zweiten Ausführungsbeispiel für Dauerkontaktgabe eingerichtet sein. Es wird hierbei nahezu derselbe Kontaktgeber wie beim ersten Ausführungsbeispiel verwendet, wobei lediglich nach Abb. 5 der Bund 8 am Schalthebel 1 weggelassen ist. Es wird - wie in Abb. 5 dargestellt - durch das Kippen der Kontaktplatte 6 um die Kanten der quadratischen Auflagefläche 7 der Kontakt durch den Druck der Feder 5 und den Druckbolzen 4 hergestellt. Der Schalthebel 1 bleibt in der Schaltstellung stehen und zeigt den zuletzt geschalteten Gang an. Wird der Schalthebel in eine andere Schaltstellung bewegt, so kippt die Kontaktplatte 6 um die entsprechende Kante der quadratischen Auflagefläche 7, und es wird für die nächsteGetriebestufeKontakt gegeben.The circuit for the reverse gear is with the push button 12 over contact 13 closed. If the gearbox is to be shifted with preselection, so must the contactor according to the second embodiment for permanent contact be set up. It will be almost the same contactor as with the first one Embodiment used, wherein only after Fig. 5 of the collar 8 on the shift lever 1 is omitted. It is - as shown in Fig. 5 - by tilting the contact plate 6 around the edges of the square support surface 7 of the contact by the pressure of the Spring 5 and the pressure pin 4 made. The shift lever 1 remains in the shift position and shows the last gear used. If the gear lever is turned into a moved other switching position, the contact plate 6 tilts to the corresponding one Edge of the square support surface 7, and it will contact for the next gear stage given.
Beim Vorwählsystem wird-wie bereits erwähnterst beim Betätigen der Kupplung der Stromkreis geschlossen. Nun kommt es häufig vor, daß im Anfahrgang die Kupplung sehr oft und sehr lange betätigt werden muß, z. B. an Verkehrsampeln und an Stoppstellen. Dabei würde nun ein unzulässiger Stromverbrauch eintreten, und außerdem würden die hochbelasteten Schaltspulen durchbrennen.In the case of the preselection system, as already mentioned, only when the Coupling the circuit closed. Now it often happens that in the starting gear the clutch must be operated very often and for a long time, e.g. B. at traffic lights and at stopping points. This would result in inadmissible electricity consumption, and in addition, the heavily loaded switching coils would burn out.
Erfindungsgemäß wird daher am Kontakt für den 1. Gang eine hier nicht dargestellte Anschlagfeder angebracht, welche beim Loslassen des Schalthebels 1 den Kontakt wieder abhebt. Dadurch .entsteht zwar der Nachteil, daß der 1. Gang nicht vorgewählt werden kann. Die Vorwählung ist aber im 1. Gang nicht so wichtig, da es sich um den Anfahrgang handelt. Es wird also auf den Vorteil der Vorwählung bewußt verzichtet, um einen unzulässigen Stromverbrauch und ein Durchbrennen der Schaltspulen zu vermeiden.According to the invention, there is therefore no one here on the contact for 1st gear Stop spring shown attached, which when you let go of the shift lever 1 the contact picks up again. This has the disadvantage that 1st gear cannot be selected. The preselection is not so important in 1st gear, since it is the starting gear. So it will take advantage of the preselection deliberately refrained from inadmissible power consumption and a burnout of the Avoid switching coils.
