Description

Die Erfindung betrifft eine Führungsvorrichtung für eine Laufrolle gemäß dem Oberbegriff des Patentanspruches 1.The The invention relates to a guide device for one Roller according to the preamble of claim 1.

In der gattungsbildenden DE 44 27 191 C2 ist eine Führungsvorrichtung für eine Laufrolle geoffenbart, die sich um eine Achse dreht und eine Laufbahn entlang einer zu dieser Rollenachse parallelen Berührungslinien kontaktiert, wobei die Laufrolle um eine Schwenkachse, die auf der Ebene, die von der Berührungslinie der Laufrolle mit der Laufbahn und der Rollenachse definiert wird, lotrecht steht, verschwenkbar ist.In the generic DE 44 27 191 C2 there is disclosed a guide device for a caster which rotates about an axis and contacts a raceway along lines of contact parallel to that roller axis, the caster being about a pivot axis, that on the plane, that of the contact line of the caster with the raceway and the roller axis is defined, is perpendicular, is pivotable.

Mit der hierin geoffenbarten Führungsvorrichtung wird das Problem der Flächenpressung zwischen Rad und Führung optimal gelöst. Die Einsatzmöglichkeit dieser Entwicklung ist aber durch die Führungsbahn dieser Drehbewegung oberhalb des Rades stark eingeschränkt.With the guide device disclosed herein becomes the problem of surface pressure between the bike and the guide optimally solved. The application possibility But this development is due to the guideway of this rotary motion severely limited above the wheel.

Vor allem bei Fahrzeugen, wie Automobil oder Eisenbahn, ist die Anforderung eines sich der Laufbahn anpassenden Radsystems gegeben, aber durch die störende Führungsbahn der Drehbewegung nicht umsetzbar.In front especially in vehicles, such as automobiles or railways, is the requirement given a career adaptive wheel system, but by the disturbing guideway the rotational movement can not be implemented.

Gemäß dem Stand der Technik werden die Radsysteme um ihre Hochachse starr geführt. Um das Problem der Kontaktfläche Rad/Fahrbahn (Schiene) zu lösen, werden verschiedene technische Kompromisse akzeptiert, die beispielsweise beim Automobil im Radsturz und bei der Eisenbahn darin bestehen, daß die Schienenkontur als Kurve ausgeführt ist.According to the state Technically, the wheel systems are rigidly guided around their vertical axis. To that Problem of contact surface Wheel / road (rail) to solve, Various technical compromises are accepted, for example in the car in the camber and in the railway consist in that the Rail contour executed as a curve is.

Die DE 295 19 108 U1 zeigt eine Radaufhängung mit Schiebefüh rungen an einem gekrümmten Führungsstab. Ein Radträger bewegt sich so, daß die Schwenkachse in Höhe der Radachse liegt.The DE 295 19 108 U1 shows a suspension with Schiebefüh ments on a curved guide rod. A wheel carrier moves so that the pivot axis is equal to the wheel axle.

Aufgabe der Erfindung ist es, ein Radschwenksystem zu erhalten, das ohne technische Einschränkung Linienkontakt einer zylindrischen Radlauffläche und einer ebenen Laufbahn garantiert, aber eine einseitige Aufhängung besitzt, um die Einsatzmöglichkeit auf andere Systeme als die Fördertechnik auszudehnen.task The invention is to obtain a Radschwenksystem that without technical restriction Line contact of a cylindrical wheel tread and a flat track guaranteed, but owns a one-sided suspension to the possible application on systems other than conveyor technology expand.

Diese Aufgabe wird durch die im einzigen Patentanspruch angegebenen Merkmale gelöst.These The object is achieved by the features specified in the single claim solved.

Die Erfindung wird im folgenden anhand der Zeichnung näher erläutert. Dabei zeigen dieThe The invention will be explained in more detail below with reference to the drawing. there show the

1 bis 3 eine erfindungsgemäße Vorrichtung. 1 to 3 a device according to the invention.

Die 1, 2, 3 zeigen eine verstellbare Rolle 1 mit einer Drehachse 12 und einseitiger Anlenkung, wobei der Schwenkmittelpunkt (Schwenkachse 7) normal auf die durch die Drehachse 12 und die Berührlinie 13 definierte Ebene zumindest nahe der Lauffläche 2 liegt. Die Kraftübertragung der Radlast erfolgt über mindestens zwei nicht zusammenfallende Anlenkpunkte 3, 4, die frei gewählt in der Ebene liegen, wobei jedoch ihre Laufbahn jeweils als konzentrischer Kreis 5 bzw. 6 um die Schwenkachse 7 definiert ist.The 1 . 2 . 3 show an adjustable role 1 with a rotation axis 12 and one-sided articulation, wherein the pivot center (pivot axis 7 ) normal to the through the axis of rotation 12 and the touch line 13 defined plane at least near the tread 2 lies. The power transmission of the wheel load via at least two non-coincident articulation points 3 . 4 , which are freely selected in the plane, but their career each as a concentric circle 5 respectively. 6 around the pivot axis 7 is defined.
