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 setpoint transmitter flanged on one side, which has an actuating shaft connected to an actuating lever and supported by two bearings. Such throttle body are present in motor vehicles, for example for speed control or idle control, the throttle valve is motor-adjustable.
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 the case of throttle valve bodies of this type, the throttle valve shaft must not be connected to the actuating shaft in a rotationally fixed manner be so that the setpoint of the setpoint generator is not at the same time by the movements of the throttle valve shaft can be adjusted. If the control shaft and the throttle valve were connected to one another in a rotationally fixed manner, then 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 supports are the mounting of the actuating shaft because of the space in the engine compartment in the area of the throttle valve connector are very cramped and therefore the setpoint generator must be as compact as possible. You could have the space for the storage of the control shaft on the Save the side of the throttle valve if you firmly connect the control shaft to the throttle valve shaft or would train them in one piece with her. Then, however, the previously 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 a throttle body of the type mentioned train that he builds as compact as possible, but coupling the actuating shaft to the throttle valve shaft can be avoided.
Diese Aufgabe wird erfindungsgemäß gelöst, durch die Merkmale gemäß Anspruch 1.This object is achieved according to the invention by the features according to claim 1.
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.With this design, the positioning shaft can be dispensed with on the side of the throttle valve shaft because it is held on one side by the throttle valve shaft. A turning of the control shaft through the throttle valve shaft is excluded, however, since the actuating shaft can be rotated in the throttle valve shaft is stored. Thanks to the invention, the size of the throttle body can be reduced without that this results 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 flap being raised due to an error can be achieved if the positioning of the control shaft in or on the throttle valve shaft two relatively has mutually rotatable bearing surface pairs. Such storage is redundant. Should it be one Blocking of two related storage areas come up, so the other two storage areas can turn the other pair of bearing surfaces relative to each other so that the rotatable bearing is obtained remains.
Konstruktiv besonders einfach ist der Drosselklappenstutzen ausgebildet, wenn gemäß einer vorteilhaften 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 connector is particularly simple in construction, if according to an advantageous Embodiment of the invention, the actuating shaft with a bearing pin rotatably engages 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 control shaft and the throttle valve shaft can be compensated 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 cost is particularly low if the bearing bush is made from a bearing metal consists. This allows very good frictional relationships between the bearing journal and the bearing bush achieve 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 used Form crowned on the outside.
Eine weitere Ausführungsform der Erfindung, die ebenfalls zwei unabhängig voneinander verdrehbare 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 independently rotatable bearing surface pairs has, is that in the 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 an adverse effect, if According to another development of the invention, the bearing pin in a bearing bore with a spherical bearing journal and is supported in the other bearing bore with a cylindrical bearing journal.

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 adjusting
