Abstract
Description
Es ist bekannt, daß es mehrere homokinetische und quasi- homokinetische, zentrierte Doppelkardangelenke gibt (Dudita, F., Cuplaje mobile homocinetice - Homokinetische bewegliche Kupplungen -, Editura Tehnica, Bucuresti, 1974).It is known that there are several homokinetic and quasi- homokinetic, centered double cardan joints (Dudita, F., Cuplaje mobile homocinetice - homokinetic flexible couplings -, Editura Tehnica, Bucuresti, 1974).
Die älteste bekannte homokinetische Kupplung ist in Deutschland im Jahre 1901 unter 1 36 605 patentiert worden. Sehr bekannt sind die Retel-Kupplung und G.W.B.- Kupplung, die unter anderen konstruktiven Varianten patentiert wurden, zum Beispiel FR-PS 14 08 856, US-PS 33 01 008.The oldest known homokinetic coupling is in Germany patented under 1 36 605 in 1901 been. The Retel coupling and G.W.B.- Coupling, among other design variants were patented, for example FR-PS 14 08 856, US-PS 33 01 008.
Die homokinetische Kupplung Borg-Wagner, patentiert zuerst in USA und dann auch in anderen Ländern (FR-PS 12 27 934) hat eine spezifische Zentriervorrichtung.The homokinetic coupling Borg-Wagner, patented first in the USA and then also in other countries (FR-PS 12 27 934) has a specific centering device.
Eine ähnliche Zentriervorrichtung hat auch die Kupplung, die unter US-PS 34 28 144 patentiert wurde. Sehr interessant ist die Zentriervorrichtung des homokinetischen Weitwinkel-Doppelkardangelenkes, das in verschiedenen konstruktiven Varianten patentiert wurde (z. B. US- PS 34 70 712) und in Serie, für Kardangelenkgetriebe zwischen Traktor und Landmaschine, von der deutschen Firma Walterscheid hergestellt wird.The clutch has a similar centering device, which was patented under US-PS 34 28 144. Very the centering device of the homokinetic is interesting Wide-angle double universal joint, which in different design variants has been patented (e.g. US PS 34 70 712) and in series, for universal joints between tractor and agricultural machine, from the German Walterscheid company is manufactured.
Alle diese homokinetisch oder quasi-homokinetisch zentrierten Doppelkardangelenke erlangen einen nicht so großen Ablenkungswinkel zwischen An- und Abtriebswellen.All of these homokinetic or quasi-homokinetic centered Double cardan joints do not reach you that way large deflection angle between the input and output shafts.
Im Gebiet der Kardangelenkgetriebe zwischen Traktor und Landmaschine soll der Ablenkungswinkel sehr groß sein, etwa 90° oder mehr. Das Doppelkardangelenk muß bis gegen 35° den Drehmoment übertragen und zeitweilig, wenn das Drehmoment nicht übertragen wird, müssen mehr als 90° zwischen An- und Abtriebswelle möglich sein. Eine Variante der Walterscheid-Kupplung erlaubt 80°, aber auch das ist nicht immer genug. Außerdem hat dieses Weitwinkelgelenk eine große diametrale Abmessung.In the area of the universal joint transmission between the tractor and Agricultural machine the deflection angle is said to be very large about 90 ° or more. The double cardan joint must up to 35 ° transmit the torque and temporarily if that Torque is not transmitted, must be more than 90 ° between the input and output shaft. A Variant of the Walterscheid coupling allows 80 °, but also that's not always enough. It also has a wide-angle joint a large diametrical dimension.
Das Problem ist, daß das homokinetische Doppelkardangelenk kleinere Abmessungen haben soll, konstruktiv einfach sein und einen größeren Ablenkungswinkel erlauben soll.The problem is that the homokinetic Double cardan joint should have smaller dimensions, be structurally simple and a larger one Should allow deflection angle.
Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß man mit einer kleinen Abmessung und einer einfachen Technologie größere Ablenkungswinkel (über 135°C, wenn das nötig ist) erlangt.The advantages achieved with the invention exist especially in that with a small dimension and a simple technology larger deflection angle (above 135 ° C if necessary).
Die elastische Zentriervorrichtung sichert eine ähnliche Veränderung der Winkel zwischen der Doppelgabel und der An- und Abtriebswelle bei einer Veränderung der Ablenkungswinkel, so daß dieses Doppelkardangelenk ein homokinetisches Weitwinkel-Doppelkardangelenk ist.The elastic centering device ensures a similar one Change the angle between the double fork and the Input and output shaft when the Deflection angle so that this double universal joint is a wide-angle constant velocity universal joint.
Das homokinetische Doppelkardangelenk elastisch zentriert wird insbesondere im Gebiet der Kardangelenkgetriebe zwischen Traktor und Landmaschine verwendet, aber auch in anderen Gebieten, z. B. als Transversalgetriebe von Pkw's oder Walzstraßen etc.The homokinetic double cardan joint is elastically centered is used particularly in the field of universal joints used between tractor and agricultural machine, but also in other areas, e.g. B. as a transverse transmission of cars or rolling mills etc.
Wie in Bild 1 gesehen wird, hat die Erfindung ein klassisches Doppelkardangelenk: Antriebswelle 1, Abtriebswelle 9, die ringförmigen Kardankreuze 2 und 8, die Doppelgabel 5 und das Nadellager 3 und 7 und die Sicherungsringe 4 und 6. Die Zentriervorrichtung ist von der Blattfeder 16 als Hauptelement gebildet. Die Blattfeder 16 ist in die Buchse 15 festgestellt bzw. beweglich in die Buchsen 10 und 21. Die gedichteten Wälzlager 14, 17 und die Wälzlager 11, 20 erlauben eine unabhängige Rotation zwischen Blattfeder 16 und Doppelgabel 5 bzw. An- und Abtriebswellen 1, 9. Die Wälzlager 11 und 20 können mit Dichtungen 12 und 19 gedichtet sein oder mit anderen Dichtungssystemen. Die Wälzlager 14, 17 sind mit den Sicherungsringen 13 und 18 axial festgestellt.As can be seen in Figure 1, the invention has a classic double cardan joint: drive shaft 1 , output shaft 9 , the ring-shaped cardan crosses 2 and 8 , the double fork 5 and the needle bearing 3 and 7 and the locking rings 4 and 6 . The centering device is formed by the leaf spring 16 as the main element. The leaf spring 16 is fixed in the bush 15 or movable in the bushes 10 and 21 . The sealed roller bearings 14, 17 and the roller bearings 11, 20 allow independent rotation between the leaf spring 16 and the double fork 5 or the input and output shafts 1, 9 . The roller bearings 11 and 20 can be sealed with seals 12 and 19 or with other sealing systems. The roller bearings 14, 17 are axially fixed with the retaining rings 13 and 18 .
In der Bewegung bilden die Achsen A₁ der Antriebswelle, A₉ der Abtriebswelle und A₅ der Doppelgabel eine Ebene. Die An- und Abtriebswelle und die Doppelgabel drehen sich um die Achsen A₁, A₉ und A₅, aber die Blattfeder bleibt immer in der Ebene und rotiert nicht. Die Blattfeder orientiert die Doppelgabel, so daß die Winkel α₁ und α₂ der Kardangelenke 01 und 02 immer gleich sind und dadurch der Homokinetismus gesichert ist.In motion, the axes A₁ of the drive shaft, A₉ of the output shaft and A₅ of the double fork form a plane. The input and output shaft and the double fork rotate about the axes A₁, A₉ and A₅, but the leaf spring always remains in the plane and does not rotate. The leaf spring orients the double fork, so that the angles α₁ and α₂ of the universal joints 01 and 02 are always the same, thereby ensuring homokinetism.
Wie in Bild 2 gesehen wird, kann die Zentriervorrichtung eine Schraubenfeder (16) haben. In diesem Fall ist die Konstruktion sehr einfach, die Feder kann sich mit dem ganzen Doppelkardangelenk drehen. In der Zeit der Übertragung der Drehbewegung orientiert die Feder die Doppelgabel, so daß die Winkel α₁ und α₂ immer gleich sind und das elastisch zentrierte Doppelkardangelenk homokinetisch ist.As can be seen in Figure 2, the centering device can have a helical spring ( 16 ). In this case, the construction is very simple, the spring can rotate with the whole double universal joint. In the time of transmission of the rotary movement, the spring orients the double fork, so that the angles α₁ and α₂ are always the same and the elastically centered double universal joint is homokinetic.
Der Ablenkungswinkel kann während der Übertragung der Drehbewegung variiert werden.The deflection angle can change during the transmission of the rotary motion can be varied.
