Description

AKTUATOR FUR DIE BETÄTIGUNG EINER MECHANISCHEN BREMSE EINES KRAFTFAHRZEUGES ACTUATOR FOR ACTUATING A MECHANICAL BRAKE OF A MOTOR VEHICLE

Die Erfindung betrifft einen Aktuator für die Betätigung einer mechanischen Bremse eines Kraftfahrzeuges, bestehend aus einem um eine Achse drehbaren Eingangselement, an dem einerseits eine Kraftquelle angreift und das andererseits in zwei verschiedene Richtungen wirkende Zugkräfte ausübt, wobei zwischen den zwei Zugkräften ein Ausgleich stattfindet. Dabei ist insbesondere an eine sogenannte Handbremse gedacht, auch wenn sie nicht mittels eines Handhebels betätigt wird, die auf die beiden Räder einer Achse wirkt; deshalb der Ausgleich der Zugkräfte.The invention relates to an actuator for the actuation of a mechanical brake of a motor vehicle, consisting of an input member rotatable about an axis, on the one hand, a power source attacks and on the other hand exerts tensile forces acting in two different directions, wherein between the two tensile forces compensation takes place. In particular, a so-called handbrake is intended, even if it is not operated by means of a hand lever, which acts on the two wheels of an axle; therefore the compensation of the tensile forces.

Aus der WO 03/008248 Al, sind Aktuatoren bekannt, auf deren Eingangselement zwei einander diametral gegenüber liegende Führungen angebracht sind, über die ein Zugelement S-förmig geführt ist. Ein Ende des Zugelements ist mit der Bremse des einen Rades verbunden, das andere mit der des anderen. Zum Anziehen der Bremse wird das Eingangselement verdreht, sodass in beiden Richtungen eine Zugkraft ausgeübt wird. Dadurch dass das Zugelement sich zwischen den Führungen verschieben kann, erfolgt der Kraftausgleich zwischen den beiden Radbremsen. Das Zugelement gleitet auf den Führungen oder es wird durch Rollen umgelenkt. Im ersteren Fall wird es durch Reibung verschlissen. Jedenfalls aber ist das Zugelement, in der Regel ein relativ steifes Drahtseil, beim Ablaufen über die Führungen einer Wechselbiegung ausgesetzt, die es auch verschleisst.From WO 03/008248 Al, actuators are known, on whose input element two diametrically opposite guides are mounted, over which a tension element is guided in an S-shape. One end of the tension element is connected to the brake of one wheel, the other with that of the other. To tighten the brake, the input member is twisted, so that a tensile force is exerted in both directions. The fact that the tension element can move between the guides, the force balance takes place between the two wheel brakes. The tension element slides on the guides or it is redirected by rolling. In the former case, it is worn by friction. In any case, however, the tension element, usually a relatively stiff wire rope, when running over the guides exposed to a bending, it also wears out.

Funktionell haften der bekannten Lösung zwei Nachteile an: Erstens fallt die Bremse an beiden Rädern, also ganz, aus, wenn das Seil an einer Stelle reisst. Zweitens ändert sich der Hebelarm beim Anziehen der Bremse in der Weise, dass er am Beginn, wenn die Bremse noch gar nicht greift, am größten und am Ende, wenn die größte Kraft benötigt wird, am kleinsten ist. Es sollte aber ge- rade umgekehrt sein. Dann wäre auch die Dauerbelastung des Zugelements bei tagelang angezogener Handbremse am kleinsten.Functionally, the known solution has two disadvantages: First, the brake on both wheels, that is, completely, falls out when the rope breaks at one point. Secondly, when the brake is applied, the lever arm changes in such a way that, at the beginning, when the brake is not yet engaged, it is the smallest and at the end, when the greatest force is needed, it is the smallest. But it should be the other way around. Then the continuous load of the tension element for days tightened handbrake would be the smallest.

Es ist somit Aufgabe der Erfindung, einen Aktuator zu schaffen, der die angeführten Nachteile vermeidet. Er soll bei kleinen Einbaumaßen einen angepass- ten Kraftverlauf und einen reibungslosen Kraftausgleich ermöglichen, ohne dass bei Seilriss die gesamte Bremse ausfallt.It is therefore an object of the invention to provide an actuator which avoids the mentioned disadvantages. With small installation dimensions, it should allow for an adapted force curve and a smooth force compensation without the entire brake failing during rope breakage.

Erfindungsgemäß wird das dadurch erreicht, dass an einander diametral gegenüber liegenden Punkten des Eingangselementes ein erster und ein zweiter zweiarmiger Hebel gelagert ist, welche beiden Hebel mit ihren ersten nach innen gerichteten Armen ineinander greifen und deren zweite nach aussen gerichtete Arme jeweils am aktuatorseitigen Ende eines Zugelementes angreifen.According to the invention this is achieved in that at diametrically opposite points of the input element, a first and a second two-armed lever is mounted, which engage both levers with their first inwardly directed arms and their second outwardly directed arms each at the actuator end of a tension element attack.

Letzteres sichert auch bei Seilriss die Funktion zumindest einer der beiden Radbremsen. Trotzdem ist dank eines weiteren Merkmales der Erfindung für einen reibungs- und verschleisslosen Kraftausgleich gesorgt. Dadurch, dass die inneren Enden der zweiarmigen Hebel ineinander greifend kinematisch gekoppelt sind, bewegt sich bei einseitigem Zug der eine äussere Arm in der- selben Richtung wie der andere. So erfolgt der Kraftausgleich mit einem Minimum an bewegten Teilen, die noch dazu Gleichteile sein können.The latter also ensures the function of at least one of the two wheel brakes even when the rope breaks. Nevertheless, thanks to a further feature of the invention provides for a frictionless and wear-free force compensation. Due to the fact that the inner ends of the two-armed levers are kinematically coupled to one another in the case of a one-sided pull, an outer arm moves in this way. the same direction as the other. Thus, the force balance is carried out with a minimum of moving parts, which can still be the same parts.

Vorzugsweise schließen die beiden Hebel mit ihren Zugelementen bei gelöster Bremse im Wesentlichen einen rechten Winkel ein (Anspruch 2). Dadurch entspricht auch der Verlauf des Übersetzungsverhältnisses den spezifischen Anforderungen: Bei Verdrehen des Eingangselementes wird der Normalabstand des Zugelements von der Schwenkachse des Eingangselementes immer kleiner, was einer progressiv steigenden Übersetzung entspricht. Die größte Kraft wird ausgeübt, wenn die Bremse fast ganz angezogen ist.Preferably, the two levers with their tension elements close when the brake is essentially a right angle (claim 2). As a result, the course of the transmission ratio also meets the specific requirements: When the input element is rotated, the normal distance of the tension element from the pivot axis of the input element becomes ever smaller, which corresponds to a progressively increasing ratio. The greatest force is exerted when the brake is almost fully tightened.

Die Hebel können auf verschiedene Weise ineinander greifend gekoppelt sein. In einer Ausfuhrungsform haben die ineinandergreifenden Arme der Hebel an ihren Enden ineinander greifende Zähne (Anspruch 3). Sie bilden dann einen Sektor eines Zahnrades, was eine exakte kinematische Kopplung bedeutet.The levers may be interlocked in various ways. In one embodiment, the interlocking arms of the lever at their ends interlocking teeth (claim 3). They then form a sector of a gear, which means an exact kinematic coupling.

In einer anderen, in der Herstellung billigeren Ausfuhrungsform hat der eine der ineinandergreifenden Arme an seinem Ende eine in Längsrichtung des Hebels verlaufende Führung und der Arm des anderen Hebels hat einen in diese Führung eingreifenden Zapfen (Anspruch 4), wobei die Führung vorzugs- weise ein Langloch ist (Anspruch 5). Zur weiteren Schonung der Zugelemente sind sie mit den äusseren Enden der Hebel (21,22;41,42; 61,62) gelenkig verbunden (Anspruch 6).In another embodiment, which is cheaper to manufacture, one of the intermeshing arms has at its end a guide extending in the longitudinal direction of the lever and the arm of the other lever has a pin engaging in this guide (claim 4), the guide preferably being one Slot is (claim 5). For further protection of the tension elements, they are articulated to the outer ends of the levers (21, 22, 41, 42, 61, 62) (claim 6).

Im Folgenden wird die Erfindung anhand von Abbildungen beschrieben und erläutert. Es stellen dar:In the following the invention will be described and explained with reference to figures. They show:

- Fig. 1 : Eine schematische Skizze einer Fahrzeugachse mit dem erfindungsgemäßen Aktuator, - Fig. 2: Eine erste Ausführungsform, entspannt,1 shows a schematic sketch of a vehicle axle with the actuator according to the invention, FIG. 2: a first embodiment, relaxed,

- Fig. 5: Wie Fig. 4, gespannt.- Fig. 5: As Fig. 4, stretched.

In Fig.l ist die Achse eines Kraftfahrzeuges angedeutet und mit 1 bezeichnet, ihr linkes Rad mit 2 und ihr rechtes Rad mit 3. Von einem erfindungsgemäßen Aktuator 4 mit einer Kraftquelle 5 fuhren Drahtseile 6,7 zu Bremshebeln 8, 9, mit denen nicht dargestellte Radbremsen betätigt werden.In Fig.l the axis of a motor vehicle is indicated and denoted by 1, her left wheel with 2 and her right wheel with 3. From an actuator 4 according to the invention with a power source 5 rode wire 6.7 to brake levers 8, 9, with which not shown wheel brakes are actuated.

Fig. 2 zeigt den Aktuator der Radbremsen in ungespannter Stellung, das heißt, die Radbremsen sind gelöst. In einem nicht dargestellten Aktuatorträger ist ein Eingangselement 10 um eine Achse 11 drehbar gelagert. Das Eingangselement 10 ist hier eine Kreisscheibe, an deren Peripherie eine Kraftquelle, hier ein elektrischer Getriebemotor über ein Zahnrad 12, angreift. An dem Eingangselement 10 ist in ersten Punkten 13, 14 ein erster Hebel 15 und ein zweiter Hebel 16 schwenkbar gelagert. Der Punkt ist hier beispielsweise ein Zapfen. Die Hebel 15,16 sind zweiarmige Hebel mit den inneren Armen 15a, 16a und den äusseren Armen 15b, 16b. Die inneren Arme 15a, 16a haben an ihren inneren Enden ineinander greifende Zähne 17,18, die jeweils vorzugs- weise Segmente eines Zahnrades sind.Fig. 2 shows the actuator of the wheel brakes in an untensioned position, that is, the wheel brakes are released. In an actuator carrier, not shown, an input element 10 is rotatably mounted about an axis 11. The input element 10 is here a circular disk, on whose periphery a power source, here an electric geared motor via a gear 12, engages. At the input element 10, a first lever 15 and a second lever 16 is pivotally mounted in first points 13, 14. The point here is for example a pin. The levers 15,16 are two-armed lever with the inner arms 15a, 16a and the outer arms 15b, 16b. The inner arms 15a, 16a have at their inner ends interlocking teeth 17,18, which are each preferably segments of a gear.

An zweiten Punkten 21, 22 nahe den äusseren Enden der äusseren Arme 15b, 16b greifen die zu den Radbremsen führenden Zugmittel 6, 7 an. Die Zugmittel 6, 7 sind Drahtseile, die stellenweise von einer Hülle umgeben sind und so einen Bowdenzug bilden, was nicht dargestellt ist. In der gezeigten ungespannten Stellung schließen die Arme 15,16 mit den Zugmitteln 6,7 ungefähr einen rechten Winkel ein. Bei symmetrischer Einstellung, wenn weder Kraft- noch Wegunterschiede auszugleichen sind, liegen die ersten PunkteAt second points 21, 22 near the outer ends of the outer arms 15b, 16b, the traction means 6, 7 leading to the wheel brakes engage. The traction means 6, 7 are wire ropes, which are surrounded in places by a sheath and form a Bowden cable, which is not shown. In the illustrated untensioned position, the arms 15,16 close with the traction means 6,7 about a right angle. For symmetrical adjustment, if neither Power or path differences are to be compensated, are the first points

13,14 und die zweiten Punkte 21,22 ungefähr auf einer Linie.13,14 and the second points 21,22 approximately on a line.

Die gespannte Stellung der Fig. 3 wird erreicht, indem das Zahnrad 12 das Eingangselement 10 um einen rechten Winkel gegen den Uhrzeigersinn dreht. In dieser Stellung sind die Bezugszeichen mit einem Apostroph versehen. Der dabei von den dritten Punkten 21, 22 bis zu der Stellung 21 ', 22' erzeugte Hub ist mit 23 bezeichnet. Bei dieser Bewegung verringert sich der Abstand 26 des Zugmittels 7 auf den radialen Abstand 26'. Dadurch ist die Kraftübersetzung umso höher, je näher man sich der gespannten Stellung nähert.The cocked position of Fig. 3 is achieved by the gear 12, the input member 10 rotates by a right angle in the counterclockwise direction. In this position, the reference numerals are provided with an apostrophe. The stroke generated by the third points 21, 22 up to the position 21 ', 22' is designated by 23. During this movement, the distance 26 of the traction means 7 reduces to the radial distance 26 '. As a result, the closer you get to the tensioned position, the higher the force transmission.

Die Ausfuhrungsform der Fig. 4 unterscheidet sich von der vorhergehenden durch eine andere Ausbildung ineinandergreifenden Teile der beiden Hebel und dadurch, dass als Kraftquelle ein Handhebel 32 vorgesehen ist, der hier direkt auf das Eingangselement wirkt. Die Bezugszeichen der der vorherge- henden Ausfuhrungsform entsprechenden Teile sind um 20 erhöht. In den ersten Punkten 33, 34 des Eingangselementes 30 ist wieder jeweils ein erster Hebel 35 und ein zweiter Hebel 36 schwenkbar gelagert. Diese Hebel 35, 36 sind hier um die ersten Punkte 33,34 schwenkbare zweiarmige Hebel, deren innere Arme 35 a, 36a ineinander greifen und an deren äusseren Armen 35b,36b in Punkten 41,42 die Zugmittel 6,7 angreifen. Die Punkte können auch wieder Zapfen oder Ausnehmungen für verdickte Enden der Zugmittel sein, was im Detail nicht dargestellt ist.The embodiment of Fig. 4 differs from the preceding by another embodiment interlocking parts of the two levers and in that as a power source, a hand lever 32 is provided, which acts directly on the input member. The reference numerals of the parts corresponding to the previous embodiment are increased by 20. In the first points 33, 34 of the input element 30, in each case a first lever 35 and a second lever 36 are pivotally mounted again. These levers 35, 36 are pivotable about the first points 33,34 two-armed lever, the inner arms 35 a, 36 a interlock and engage the traction means 6,7 at the outer arms 35 b, 36 b in points 41,42. The points can also be pins or recesses for thickened ends of the traction means, which is not shown in detail.

Die kinematisch gekoppelten inneren Arme 35a, 36a überdecken einander teilweise, weshalb der überdeckte Teil des Armes 35a strichliert ist. Er hat einen Zapfen 37, der in eine Führung 38, hier ein Langloch, eingreift. An zweiten Punkten 41, 42 sind wieder die Zugmittel 6, 7 angebunden. Die gespannte Stellung der Fig. 5 wird durch Umlegen des Handhebels 32 um einen rechten Winkel gegen den Uhrzeigersinn erreicht. In dieser Stellung sind die Bezugszeichen wieder mit einem Apostroph versehen. Der dabei von den dritten Punkten 41, 42 zurückgelegte Hub ist mit 43 bezeichnet, der radiale Abstand der Zugmittel 7 mit 46 beziehungsweise 46'. In dem Maße, in dem sich dieser radiale Abstand verringert, steigt die auf die Zugmittel 6, 7 ausgeübte Kraft bei unveränderter auf das Eingangselement 10,30 wirkender Kraft. The kinematically coupled inner arms 35a, 36a partly overlap each other, so that the covered part of the arm 35a is dotted. He has a pin 37, which engages in a guide 38, here a slot. At second points 41, 42 again the traction means 6, 7 are connected. The cocked position of Fig. 5 is achieved by tilting the hand lever 32 by a right angle in the counterclockwise direction. In this position, the reference numerals are again provided with an apostrophe. The case covered by the third points 41, 42 stroke is designated 43, the radial distance of the traction means 7 with 46 and 46 '. As this radial distance decreases, the force exerted on the traction means 6, 7 increases while the force acting on the input element 10, 30 is unchanged.
