Description

Die Erfindung betrifft einen Drosselklappenstutzen mit einem an einer Seite angeflanschten Sollwertgeber, welcher eine mit einem Stellhebel verbundene, durch zwei Lager gelagerte Stellwelle hat. Solche Drosselklappenstutzen sind in Kraftfahrzeugen vorhanden, bei denen beispielsweise für eine Geschwindigkeitsregelung oder Leerlaufregelung die Drosselklappe motorisch verstellbar ausgebildet ist.The invention relates to a throttle valve connector with a flange mounted on one side of the setpoint generator, which has a control shaft connected to a control lever and supported by two bearings. Such throttle valve bodies are present in motor vehicles in which the throttle valve is designed to be motor-adjustable, for example for speed control or idling control.

Bei Drosselklappenstutzen dieser Art darf die Drosselklappenwelle nicht drehfest mit der Stellwelle verbunden sein, damit durch die Bewegungen der Drosselklappenwelle nicht zugleich der Sollwert des Sollwertgebers verstellt werden kann. Wären die Stellwelle und die Drosselklappe miteinander drehfest verbunden, so würde eine durch einen Fehler in Offenrichtung fahrende Drosselklappe zwangsläufig den Sollwert höher einstellen und es käme zu einem vollständigen öffnen der Drosselklappe.In throttle valve bodies of this type, the throttle valve shaft must not be connected to the actuating shaft in a rotationally fixed manner, so that the setpoint of the setpoint generator cannot be adjusted by the movements of the throttle valve shaft. If the control shaft and the throttle valve were connected to one another in a rotationally fixed manner, a throttle valve traveling in the open direction due to a fault would inevitably set the setpoint higher and the throttle valve would open completely.

Schwierigkeiten bereitet bei solchen Drosselklappenstutzen die Lagerung der Stellwelle, da die Platzverhältnisse im Motorraum im Bereich des Drosselklappenstutzens sehr beengt sind und deshalb der Sollwertgeber möglichst kompakt ausgebildet sein muß. Man könnte den Platz für die Lagerung der Stellwelle auf der Seite der Drosselklappe einsparen, wenn man die Stellwelle fest mit der Drosselklappenwelle verbinden oder diese einstückig mit ihr ausbilden würde. Dann träte jedoch der zuvor angeführte Effekt auf, daß die Drosselklappenwelle den Sollwert im Sollwertgeber verstellen könnte, so daß diese Möglichkeit der Platzeinsparung nicht in Frage kommt.Difficulties with such throttle valve bodies are the mounting of the actuating shaft, since the space in the engine compartment in the area of the throttle valve body is very cramped and the setpoint generator must therefore be as compact as possible. One could save the space for the positioning of the actuating shaft on the side of the throttle valve if one would connect the actuating shaft firmly to the throttle valve shaft or form it in one piece with it. Then, however, the above-mentioned effect would occur that the throttle valve shaft could adjust the setpoint in the setpoint generator, so that this possibility of saving space is out of the question.

Der Erfindung liegt die Aufgabe zugrunde, einen Drosselklappenstutzen der eingangs genannten Art so auszubilden, daß er möglichst kompakt baut, eine Kopplung der Stellwelle mit der Drosselklappenwelle jedoch vermieden werden kann.The invention has for its object to design a throttle valve assembly of the type mentioned in such a way that it is as compact as possible, but coupling of the actuating shaft to the throttle valve shaft can be avoided.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das der Drosselklappenwelle zugewandte Ende der Stellwelle in oder auf der Drosselklappenwelle relativ zur Drosselklappenwelle drehbar gelagert ist.This object is achieved in that the end of the actuating shaft facing the throttle valve shaft is rotatably mounted in or on the throttle valve shaft relative to the throttle valve shaft.

Durch diese Gestaltung kann auf die Lagerung der Stellwelle auf der Seite der Drosselklappenwelle verzichtet werden, da sie von der Drosselklappenwelle an einer Seite gehalten wird. Ein Verdrehen der Stellwelle durch die Drosselklappenwelle ist jedoch ausgeschlossen, da die Stellwelle verdrehbar in der Drosselklappenwelle gelagert ist. Dank der Erfindung läßt sich die Baugröße des Drosselklappenstutzens vermindern, ohne daß dadurch sicherheitstechnische Nachteile eintreten.This design means that the actuating shaft on the side of the throttle valve shaft can be dispensed with, since it is held on one side by the throttle valve shaft. However, twisting of the actuating shaft by the throttle valve shaft is excluded, since the actuating shaft is rotatably mounted in the throttle valve shaft. Thanks to the invention, the size of the throttle valve body can be reduced without this resulting in safety-related disadvantages.

Eine besonders hohe Sicherheit gegen ein durch einen Fehler hervorgerufenes Hochfahren der Drosselklappe läßt sich erreichen, wenn die Lagerung der Stellwelle in oder auf der Drosselklappenwelle zwei relativ zueinander verdrehbare Lagerflächenpaare hat. Eine solche Lagerung ist redundant. Sollte es zu einem Blockieren von zwei zusammengehörigen Lagerflächen kommen, so können sich die beiden anderen Lagerflächen des anderen Lagerflächenpaares relativ zueinander verdrehen, so daß die drehbare Lagerung erhalten bleibt.A particularly high level of security against the throttle valve being raised due to an error can be achieved if the mounting of the actuating shaft in or on the throttle valve shaft has two pairs of bearing surfaces which can be rotated relative to one another. Such storage is redundant. If two associated bearing surfaces are blocked, the other two bearing surfaces of the other pair of bearing surfaces can rotate relative to one another, so that the rotatable bearing is retained.

Konstruktiv besonders einfach ist der Drosselklappenstutzen ausgebildet, wenn gemäß einervorteilhaften Ausgestaltung der Erfindung die Stellwelle mit einem Lagerzapfen verdrehbar in eine Lagerbuchse greift, welche ihrerseits verdrehbar in eine Lagerbohrung der Drosselklappenwelle angeordnet ist.The throttle valve assembly is particularly simple in construction if, according to an advantageous embodiment of the invention, the actuating shaft rotatably engages with a bearing pin in a bearing bush, which in turn is arranged rotatably in a bearing bore of the throttle valve shaft.

Fluchtungsfehler zwischen der Stellwelle und der Drosselklappenwelle können dadurch ausgeglichen werden, daß der Lagerzapfen ballig ist.Alignment errors between the actuating shaft and the throttle valve shaft can be compensated for by the fact that the bearing journal is spherical.

Die Fertigungskosten sind insgesamt besonders niedrig, wenn die Lagerbuchse aus einem Lagermetall besteht. Es lassen sich dadurch sehr gute Reibverhältnisse zwischen dem Lagerzapfen und der Lagerbuchse einerseits und andererseits zwischen der Lagerbuchse und der Wandung der Lagerbohrung erzielen.The overall manufacturing costs are particularly low if the bearing bush consists of a bearing metal. This makes it possible to achieve very good frictional relationships between the bearing journal and the bearing bush on the one hand and on the other hand between the bearing bush and the wall of the bearing bore.

Statt zum Ausgleich von Fluchtungsfehlern den Lagerzapfen ballig auszubilden, kann man auch die Lagerbuchse außenseitig ballig ausbilden.Instead of making the bearing journal spherical to compensate for misalignment, the bearing bush can also be spherical on the outside.

Eine weitere Ausführungsform der Erfindung, die ebenfalls zwei unabhängig voneinander verdreh bare Lagerflächenpaare aufweist, besteht darin, daß in den einander zugewandten Stirnflächen der Drosselklappenwelle und der Stellwelle fluchtend zueinander jeweils eine Lagerbohrung vorgesehen ist und daß ein Lagerstift verdrehbar in beide Lagerbohrungen greift.Another embodiment of the invention, which also has two mutually independently rotatable bearing surface pairs, is that in the mutually facing end faces of the throttle valve shaft and the actuating shaft in alignment with each other, a bearing bore is provided and that a bearing pin rotatably engages in both bearing bores.

Die Stellwelle ist zuverlässig gehalten, ohne daß sich geringe Fluchtungsfehler störend auswirken, wenn gemäß einer anderen Weiterbildung der Erfindung der Lagerstift in einer Lagerbohrung mit einem balligen Lagerzapfen und in der anderen Lagerbohrung mit einem zylindrischen Lagerzapfen gelagert ist.The actuating shaft is held reliably without minor misalignments having a disruptive effect if, according to another development of the invention, the bearing pin is mounted in a bearing bore with a spherical bearing journal and in the other bearing bore with a cylindrical bearing journal.

Die Erfindung läßt zahlreiche Ausführungsformen zu. Zur weiteren Verdeutlichung sind drei davon in der Zeichnung dargestellt und werden nachfolgend beschrieben. Diese zeigt in

  • Fig. 1 einen Schnitt durch einen Randbereich eines Drosselklappenstutzens nach der Erfindung mit einem Sollwertgeber,
  • Fig. 2 eine Seitenansicht des Verbindungsbereiches einer Stellwelle mit einer Drosselklappenwelle des Drosselklappenstutzens in einer gegenüber Figur 1 abgewandelten Ausführung,
  • Fig. 3 eine Seitenansicht einer zweiten Ausführungsform einer Stellwelle mit einer Drosselklappenwelle des Drosselklappenstutzens.
The invention allows numerous embodiments. For further clarification, three of them are shown in the drawing and are described below. This shows in
  • 1 shows a section through an edge region of a throttle valve assembly according to the invention with a setpoint generator,
  • 2 shows a side view of the connection area of an actuating shaft with a throttle valve shaft of the throttle valve connector in a variant modified from FIG. 1,
  • Fig. 3 is a side view of a second embodiment of an actuating shaft with a throttle valve shaft the throttle body.

Die Figur 1 zeigt teilweise einen Drosselklappenstutzen 1, an welchem ein Sollwertgeber 2 angeflanscht ist. Im Drosselklappenstutzen 1 ist eine Drosselklappenwelle 3 drehbar gelagert, welche eine Drosselklappe 4 haltert.FIG. 1 partially shows a throttle valve connector 1, to which a setpoint generator 2 is flanged. In the throttle valve neck 1, a throttle valve shaft 3 is rotatably mounted, which holds a throttle valve 4.

Fluchtend zur Drosselklappenwelle 3 ist im Sollwertgeber 2 eine Stellwelle 5 angeordnet, welche drehfest mit einem Stellhebel 6 verbunden ist, mit dem der Sollwertgeber 2 verstellt wird, um einen gewünschten Sollwert vorzugeben. Nicht gezeigt ist in derZeichnung ein auf der dem Sollwertgeber gegenüberliegenden Seite des Drosselklappenstutzens 1 angeordneter Stellmotor, der die Drosselklappenwelle 3 entsprechend der Vorgaben des Sollwertgebers 2 verstellt.Aligned to the throttle valve shaft 3, an actuating shaft 5 is arranged in the setpoint generator 2, which is connected in a rotationally fixed manner to an actuating lever 6, with which the setpoint generator 2 is adjusted in order to specify a desired setpoint. Not shown in the drawing is a servomotor which is arranged on the side of the throttle valve connector 1 opposite the setpoint generator and which adjusts the throttle valve shaft 3 in accordance with the specifications of the setpoint generator 2.

Die Stellwelle 5 ist auf der der Drosselklappenwelle 3 abgewandten Seite auf übliche Weise mittels eines Wälzlagers 7 im Gehäuse 8 des Sollwertgebers 2 gelagert. Auf der der Drosselklappenwelle 3 zugewandten Seite greift die Stellwelle 5 mit einem Lagerzapfen 9 in eine Lagerbohrung 10, welche von der Stirnseite her in die Drosselklappenwelle 3 hineinführt. Auf dem Lagerzapfen 9, der bei dieser Ausführungsform zylindrisch ausgebildet ist, sitzt eine Lagerbuchse 11 aus einem Lagermetall, die eine ballige Außenmantelfläche hat.The control shaft 5 is mounted on the side facing away from the throttle valve shaft 3 in the usual way by means of a roller bearing 7 in the housing 8 of the setpoint generator 2. On the side facing the throttle valve shaft 3, the actuating shaft 5 engages with a bearing pin 9 in a bearing bore 10, which leads into the throttle valve shaft 3 from the front side. On the bearing pin 9, which is cylindrical in this embodiment, a bearing bush 11 made of a bearing metal is seated and has a spherical outer surface.

Die Toleranzen der Bauteile im Verbindungsbereich zwischen der Drosselklappenwelle 3 und der Stellwelle 5 sind derart, daß sich der Lagerzapfen 9 bei einer Relativbewegung zwischen der Stellwelle 5 und der Drosselklappenwelle 3 in der Lagerbuchse 11 dreht. Sollte es jedoch in diesem Bereich zu einem Festfressen kommen, dann vermag sich die Lagerbuchse 11 mit dem Lagerzapfen 9 in der Lagerbohrung 10 zu drehen.The tolerances of the components in the connection area between the throttle valve shaft 3 and the actuating shaft 5 are such that the journal 9 rotates in the bearing bush 11 when there is a relative movement between the actuating shaft 5 and the throttle valve shaft 3. However, should seizing occur in this area, then the bearing bush 11 can rotate with the bearing pin 9 in the bearing bore 10.

Bei der Ausführungsform nach Figur 2 hat zum Ausgleich von Fluchtungsfehlern der Lagerzapfen 9 der Stellwelle 5 eine ballige Oberfläche. Die Lagerbuchse 11 in der Lagerbohrung 10 ist innen und außen zylindrisch. Genau wie bei der zuvor erläuterten Ausführungsform dreht sich normalerweise der Lagerzapfen 9 in der Lagerbuchse 11, jedoch kann sich bei einer Schwergängigkeit in diesem Bereich die Lagerbuchse 11 auch in der Lagerbohrung 10 verdrehen.In the embodiment according to FIG. 2, the journal 9 of the actuating shaft 5 has a spherical surface to compensate for misalignments. The bearing bush 11 in the bearing bore 10 is cylindrical inside and outside. Exactly as in the embodiment explained above, the bearing journal 9 normally rotates in the bearing bush 11, but if the binding is difficult in this region, the bearing bush 11 can also rotate in the bearing bore 10.

Gemäß Figur 3 ist fluchtend zur Lagerbohrung 10 auch in der Stirnfläche der Stellwelle 5 eine Lagerbohrung 12 vorgesehen. Ein Lagerstift 13 sitzt mit seinem balligen Zapfen 9 verdrehbar in der Lagerbohrung 10 und hat auf seiner gegenüberliegenden Seite einen zylindrischen Zapfen 14, der in der Lagerbohrung 12 verdrehbar sitzt. Auf diese Weise sind wiederum zwei Lagerstellen verwirklicht, so daß bei einem Blockieren der einen Lagerstelle die andere eine Drehbewegung zulassen kann.According to FIG. 3, a bearing bore 12 is also provided in alignment with the bearing bore 10 in the end face of the actuating shaft 5. A bearing pin 13 is rotatably seated with its spherical pin 9 in the bearing bore 10 and has on its opposite side a cylindrical pin 14 which is rotatably seated in the bearing bore 12. In this way, two bearing points are again realized, so that if one bearing point is blocked, the other can allow a rotary movement.

Bei den Ausführungsbeispielen gemäß den Figuren 1 und 2 greift die Stellwelle 5 jeweils mit einem Zapfen 9 in die Lagerbohrung 10 der Drosselklappenwelle 3. Möglich ist natürlich auch eine kinematische Umkehr, gemäß der die Drosselklappenwelle 3 mit einem Zapfen in die Stellwelle greifen würde. Denkbar ist es auch, daß die Stellwelle nicht in die Drosselklappenwelle, sondern über die Drosselklappenwelle greift.In the exemplary embodiments according to FIGS. 1 and 2, the actuating shaft 5 engages with a pin 9 in the bearing bore 10 of the throttle valve shaft 3. Of course, a kinematic reversal is also possible, according to which the throttle valve shaft 3 would engage in the actuating shaft with a pin. It is also conceivable that the actuating shaft does not engage in the throttle valve shaft, but rather via the throttle valve shaft.
