Abstract
Description
Die Erfindung betrifft eine Stelleinrichtung für ein Steuerelement, insbesondere für die Drosselklappe eines Fahrzeugmotors mit den Merk malen des Oberbegriffs des Anspruches 1.The invention relates to an actuating device for a control element, especially for the throttle valve of a vehicle engine with the Merk paint the preamble of claim 1.
Eine derartige Stelleinrichtung ist aus der DE-OS 21 19 248 bekannt. Dort ist das Steuerelement die Drosselklappe eines Motors, der Betäti gungshebel ist das Gaspedal und zwischen das aufgetrennte Gestänge ist eine Zylinder-Kolbenanordnung mit zwei Kolben eingeschaltet, von denen je einer mit einem der Gestängeteile verbunden ist. Die Kolben teilen den Zylinder in drei Kammern, von denen die zwischen den beiden Kolben liegende mit einer von den angetriebenen Rädern angetriebenen Pumpe und die beiden andern von einer von den nicht angetriebenen Rädern ange triebenen Pumpe verbunden sind. Drehen die angetriebenen Räder durch, so wird das Gestänge verlängert und damit bei vorgegebener Gaspedal stellung die Drosselklappe im Sinne einer Verringerung der Energiezu fuhr (Verringerung des Antriebsdrehmoments) verstellt.Such an actuator is known from DE-OS 21 19 248. There the control element is the throttle valve of an engine, the actuator The control lever is the accelerator pedal and is between the separated linkage a cylinder-piston arrangement with two pistons turned on, one of which one is connected to one of the rod parts. Split the pistons the cylinder in three chambers, the one between the two pistons lying with a pump driven by the driven wheels and the other two by one of the non-driven wheels driven pump are connected. Spin the driven wheels so the linkage is extended and with a given accelerator pedal position the throttle valve in the sense of reducing the energy supply drove (reduction of the drive torque) adjusted.
Auch bei sogenannten E-Gaslösungen sind Verstellungen der Betriebsmit
telzufuhr bei Auftreten von Antriebsschlupf bzw. Motorschleppmoment
bekannt.
Even with so-called e-gas solutions, adjustments of the operating agent supply are known when traction slip or engine drag torque occur.
Demgegenüber hat die erfindungsgemäße Einstellvorrichtung den Vorteil, einerseits bei Fahrzeugen ohne E-Gas eine Antriebsschlupf- bzw. Motor schleppmomentenregelung anwenden zu können und andererseits sehr viel ein facher als der Stand der Technik zu sein. Außerdem sind Stellbewegungen am Gaspedal kaum fühlbar. Bei Verwendung von mehreren Rädern ist eine Wegübersetzung möglich. Läßt man durch eines der Räder die Verstellung anzeigen (Weggeber), so gibt die Anzeige immer die Summenverstellung, z.B. der Drosselklappe durch Gaspedal und z.B. aufgrund von ASR an. Es kann natürlich auch ein anderes Element zur Antriebsdrehmomentänderung da mit verstellt werden. Die Stelleinrichtung läßt sich in einfacher Weise an jedes Fahrzeug anpassen. Außerdem ist kein Eingriff an den konstruktiven Gegebenheiten des Steuerelements notwendig.In contrast, the setting device according to the invention has the advantage on the one hand, a drive slip or motor in vehicles without E-gas to be able to apply drag torque control and on the other hand a lot to be simpler than the state of the art. There are also adjustment movements barely noticeable on the accelerator pedal. When using multiple wheels is one Path translation possible. If you let the adjustment through one of the wheels display (travel sensor), the display always shows the total adjustment, e.g. the throttle valve by accelerator pedal and e.g. due to ASR. It there can of course be another element for changing the drive torque can be adjusted with. The actuating device can be turned on in a simple manner customize each vehicle. In addition, there is no interference with the constructive Conditions of the control necessary.
Als flexibles Teil kann ein Seil, ein Band, ein Zahnriemen oder eine Kette verwendet werden.A rope, a band, a toothed belt or a can be used as a flexible part Chain can be used.
Zur Verstellung des Rads kann ein Motor vorgesehen sein, insbesondere ist jedoch ein Elektromagnet vorgesehen. Dieser kann eine Proportio nalverstellung oder eine Verstellung in Stufen bewirken.A motor can be provided to adjust the wheel, in particular however, an electromagnet is provided. This can be a proportion effect adjustment or adjustment in stages.
Anhand der Zeichnung werden Ausführungsbeispiele der Erfindung erläu tert. Es zeigenExemplary embodiments of the invention are explained with the aid of the drawing tert. Show it
Fig. 1 ein Ausführungsbeispiel mit drei Rädern, Fig. 1 shows an embodiment with three wheels,
Fig. 2 ein vereinfachtes Ausführungsbeispiel mit zwei Rädern, Fig. 2 is a simplified embodiment with two wheels,
Fig. 3 ein weiter vereinfachtes Ausführungsbeispiel mit einem Rad, Fig. 3 is a further simplified embodiment with a wheel,
Fig. 4 ein weiter vereinfachtes Ausführungsbeispiel mit einem Rad. Fig. 4 shows a further simplified embodiment with a wheel.
In Fig. 1 ist ein Gaspedal mit 1, ein geteilter Bowdenzug mit 2 a und 2 b, ein Einstellhebel mit 3, eine Feder mit 4, eine Drosselklappe mit 5 und eine in den Bowdenzug 2 eingeschaltete, in der Länge veränderbare mechanische Verbindung mit 6 bezeichnet.In Fig. 1 is an accelerator pedal with 1 , a divided Bowden cable with 2 a and 2 b , an adjusting lever with 3 , a spring with 4 , a throttle valve with 5 and a switched in the Bowden cable 2 , length-adjustable mechanical connection with 6 designated.
Die veränderbare mechanische Verbindung 6, die mit den beiden Teilen des Bowdenzuges 2 verbunden ist, enthält ein flexibles Band, das hier als Zahnriemen ausgebildet ist und das teilweise um ein Umlenkrad 8, ein Stellrad 9 und ein Geberrad 10, die als Zahnräder ausgebildet sind (sh. Fig. 1a) herumgeführt ist. Während der Abstützpunkt des Umlenkrads 8 und des Geberrads 10 fest steht, ist das Stellrad 9 mit dem Anker 11 eines Elektromagneten 12 mit einer Wicklung 13 verbunden.The changeable mechanical connection 6 , which is connected to the two parts of the Bowden cable 2 , contains a flexible band, which is designed here as a toothed belt and which is partially around a deflection wheel 8 , a setting wheel 9 and an encoder wheel 10 , which are designed as toothed wheels ( sh. Fig. 1a) is led around. While the support point of the deflection wheel 8 and the sensor wheel 10 is fixed, the setting wheel 9 is connected to the armature 11 of an electromagnet 12 with a winding 13 .
Bei Ansteuerung der Wicklung 13 des Elektromagneten 12 erfolgt eine Ver schiebung des Ankers 11 entsprechend der angelegten Spannung nach unten, damit eine Verlängerung der zwischen Gaspedal 1 und Einstellhebel 3 wirksamen mechanischen Verbindung und damit eine entsprechende Verstel lung der Drosselklappe 5 ohne Änderung der Gaspedalstellung. Die An steuerspannung für die Elektromagnetwicklung kann durch eine von der Differenz der Drehzahlen nicht angetriebener und angetriebener Fahrzeug räder abhängige Spannung erfolgen, so daß hierdurch eine Antriebs schlupfregelung bzw. Schleppmomentregelung ermöglicht wird.When the winding 13 of the electromagnet 12 is actuated, a displacement of the armature 11 takes place in accordance with the applied voltage downward, so that an extension of the mechanical connection effective between the accelerator pedal 1 and the adjusting lever 3 and thus a corresponding adjustment of the throttle valve 5 without changing the accelerator pedal position. The control voltage for the electromagnetic winding can be done by a voltage dependent on the difference in the speeds of the non-driven and driven vehicle wheels, so that this makes a drive slip control or drag torque control possible.
Das Geberrad 10 treibt einen Weggeber 14 bekannter Bauart an (z.B. Widerstandsveränderung aufgrund einer Schleiferbewegung), so daß die Ausgangsspannung des Weggebers 14 ein Maß der Drosselklappenstellung und zwar hervorgerufen durch Gaspedalstellung und Bowdenzugverlängerung darstellt.The encoder wheel 10 drives a displacement sensor 14 of a known type (for example a change in resistance due to a wiper movement), so that the output voltage of the displacement sensor 14 represents a measure of the throttle valve position, namely caused by the accelerator pedal position and Bowden cable extension.
Fig. 2 unterscheidet sich von Fig. 1 lediglich dadurch, daß das Um lenkrad 8 entfallen ist. Fig. 2 differs from Fig. 1 only in that the order steering wheel 8 is omitted.
In Fig. 3 ist auch noch ein separates Geberrad 10 entfallen und das Stellrad 9 übernimmt noch dessen Funktion. In Fig. 3, a separate encoder wheel 10 is also omitted and the adjusting wheel 9 still takes over its function.
Der Elektromagnet 6 ist hier so ausgebildet, daß er durch Ansteuern einer ersten Wicklung 13′ den Anker 11 im Bereich 15 zu verstellen vermag und damit die Drosselklappe gegen die Kraft einer Feder 16 mit der Federkon stanten F 2 bis in die Verschließstellung bringen kann. Mit einer zweiten Wicklung 13′′ kann hier aber noch die aufgrund der Fahrpedalstellung ge schlossene Drosselklappe im Bereich 17 entgegen der Kraft der Feder 18 (F₃) geöffnet werden (bei Motorschleppmoment). Wenn die Federkonstante der Feder 4 F 1 ist, so muß hier gelten: F 1<F 2<F 3.The electromagnet 6 is designed here so that it can adjust the armature 11 in the region 15 by driving a first winding 13 'and thus the throttle valve against the force of a spring 16 with the Federkon constant F 2 can bring into the closed position. With a second winding 13 '' but here the closed due to the accelerator pedal position throttle valve in the area 17 against the force of the spring 18 ( F ₃) can be opened (at engine drag torque). If the spring constant of the spring 4 is F 1 , then the following must apply: F 1 < F 2 < F 3 .
Insbesondere bei einer Anordnung der Fig. 3 ist es vorteilhaft auch mög lich, nur die Hülle 20 des Bowdenzuges aufzutrennen. Hier wird die Seele 21 des Bowdenzuges um das Rad 9 gelegt und durch zwei z.B. an der Stellein richtung 24 angebrachte Festpunkte 22, 23 werden die Hüllenteile 20 a und b abgestützt. (Fig. 4)In particular with an arrangement of FIG. 3, it is advantageously also possible to separate only the casing 20 of the Bowden cable. Here, the soul 21 of the Bowden cable is placed around the wheel 9 and the shell parts 20 a and b are supported by two fixed points 22 , 23 , for example on the Stellin device 24 . ( Fig. 4)
