Abstract

The inner housing (2) of the two part housing containing the spiral spring (3) is fixed on the sterring shaft of the vehicle. The outer housing section (5) is so arranged that is not effected by rotation of the inner housing. (2). The inner housing (2) has a core (6) on which the spiral spring (3) is ro#nd, this core (6) being eccentric to the steering shaft (1), and providing a fixing and contact region (7) for the end of the spiral spring (3). The other end (8) of the spiral spring is fixed to the outer housing section (5). The spiral (3) is made of an electrically conducting material, and forms the electrical connection between components which rotate with respect to one another, this connection method being more reliable than slip rings.

Description

"Stromleitungsverbinder für gegen-"Power line connector for opposing

einander drehbare Bauteile11 a Die Erfindung betrifft einen Stromleitungsverbinder für gegeneinander drehbare Bauteile insbesondere von Kraftwagenlenkungen, mit einer in einem Gehäuse angeordneten, aus elektrisch leitfähigem Material bestehenden Spiralfeder, wobei das Gehäuse zweiteilig ausgebildet ist und ein inneres, mit einer Welle drehfest verbundenes Teil aufweist, das mit einem dem Aufwickeln der Spiralfeder dienenden Kern mit krs£örmigem Querschnitt ausgestattet ist, sowie weiter ein äußeres Gehäuseteil, das gegenüber dem drehbaren inneren Gehäuseteil feststehend angeordnet ist, und wobei ein Ende der Spiralfeder am Kern des inneren Gehäuseteils und das andere Ende der Spiralfeder am äußeren Gehäuseteil festgelegt ist. rotatable components11 a The invention relates to a power line connector for mutually rotatable components, in particular of vehicle steering systems, with a spiral spring made of electrically conductive material, arranged in a housing, wherein the housing is designed in two parts and an inner one, non-rotatably with a shaft having connected part, which is used with a winding of the spiral spring The core is equipped with a circular cross-section, as well as an outer housing part, which is fixedly arranged opposite the rotatable inner housing part, and one end of the coil spring at the core of the inner housing part and the other end the spiral spring is fixed on the outer housing part.

Der Einsatz derartiger Stromleitungsverbinder ist besonders dann vorteilhaft, wenn eine Betriebssicherheit gewährleistet sein muß, die z. B. durch übliche Schleifringkonstruktionen nicht sichergestellt werden kann. Diese Fälle liegen z. B. dann vor, wenn über eine Lenkhandradanordnung eines Kraftwagens Zündstron für eine Airbag-Einheit übertragen werden muß.The use of such power line connectors is particularly advantageous if operational safety must be guaranteed, the z. B. by conventional slip ring constructions not can be ensured. These cases are e.g. B. before when using a steering wheel assembly of a motor vehicle Zündstron must be transmitted for an airbag unit.

Anzustreben bei solchen Stromleitungsverbindern ist aus Gewichts- und Kostengründen eine möglichst geringe Länge der Spiralfeder.The aim for such power line connectors is due to weight and for reasons of cost, the shortest possible length of the spiral spring.

Diese wird einmal bestimmt durch die erforderliche Anzahl von Umdrehungen und zum anderen vom Durchmesser des Wikkelkernes. Da die erforderliche Anzahl von Umdrehungen festliegt, können etwaige Maßnahmen zur Verringerung der Federlänge nur beim Wickelkern ansetzen.This is determined once by the number of revolutions required and on the other hand from the diameter of the winding core. Since the required number of Revolutions is fixed, possible measures to reduce the spring length only start at the winding core.

Dessen Durchmesser wiederum wird bestimmt vom Durchmesser der Welle, an der er befestigt ist, und durch die Tatsache, daß er für eine sichere Befestigung und Kontaktierung der Spiralfeder Platz bieten muß.Its diameter in turn is determined by the diameter of the shaft, to which it is attached, and by the fact that it is securely attached and contacting the spiral spring must provide space.

Der Wellendurchmesser ist dabei nicht beliebig beeinflußbar. Der vorliegenden Erfindung lag daher die Aufgabe zugrunde, einen Wickelkern für einen Stromleitungsverbinder der vorstehend beschriebenen Gattung so auszubilden bzw.The shaft diameter cannot be influenced in any way. The present The invention was therefore based on the object of a winding core for a power line connector of the genus described above.

anzuordnen, daß er bei vorgegebener Wellenstärke bei möglichst geringem Eigendurchmesser ausreichende Befestigungsmöglichkeit für die Spiralfeder bietet.to arrange that he at a given wave strength at the lowest possible Own diameter offers sufficient fastening options for the spiral spring.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Kern gegenüber der Welle exzentrisch angeordnet ist.This object is achieved according to the invention in that the core opposite the shaft is arranged eccentrically.

Ein Ausführungsbeispiel der Erfindung soll im folgenden anhand der Zeichnung näher erläutert werden.An embodiment of the invention will be described below with reference to the Drawing will be explained in more detail.

In der Zeichnung zeigen: Fig. 1 einen Querschnitt durch einen erfindungsgemäßen Stromleitungsverbinder, und Fig. 2 einen Schnitt nach der Linie II-II in Fig. 1, wobei die Spiralfeder nicht dargestellt ist.In the drawing: FIG. 1 shows a cross section through a device according to the invention Power line connector, and FIG. 2 shows a section along the line II-II in FIG. 1, the spiral spring is not shown.

Auf einer Welle 1, die vorzugsweise die Lenkwelle eines Kraftwagens sein kann, ist unverschiebbar und undrehbar ein inneres Gehäuseteil 2 eines eine Spiralfeder 3 aufnehmenden zweiteiligen Gehäuses 4 befestigt. Das äußere Gehäuseteil 5 ist dabei in nicht dargestellter Weise so angeordnet1 daß es Drehbewegungen des inneren Gehäuseteils 2 nicht mitmacht; im Falle der Verwendung bei einer Eraftwagenlenkung wäre es also fahrzeugfest angeordnet. Das innere Gehäuseteil 2 weist dabei einen dem Aufwickeln der Spiralfeder 3 dienenden Kern 6 auf, der exzentrisch zur Welle 1 angeordnet ist. Im dargestellten Ausführungsbeispiel sind die Mittellängsachse der Welle 1 und die Mittellängsachse des Kernes 6 um den Betrag "d" gegeneinander versetzt. Durch diese versetzte Anordnung des Kernes 6 bietet dieser bei geringstmöglichem Durchmesser in seinem die Welle 1 am weitesten überragenden Bereich einen einwandfreien Befestigungs- und Kontaktierungsbereich 7 für ein Ende der Spiralfeder 3, deren anderes Ende bei 8 am äußeren Gehäuseteil 5 befestigt ist.On a shaft 1, which is preferably the steering shaft of a motor vehicle can be, an inner housing part 2 of a one is immovable and non-rotatable Spiral spring 3 receiving two-part housing 4 attached. The outer housing part 5 is arranged in a manner not shown so that there is rotational movements of the inner housing part 2 does not participate; in the case of use in vehicle steering it would be fixed to the vehicle. The inner housing part 2 has a the winding of the spiral spring 3 serving core 6, which is eccentric to the shaft 1 is arranged. In the illustrated embodiment, the central longitudinal axis of the shaft 1 and the central longitudinal axis of the core 6 by the amount "d" against each other offset. Due to this offset arrangement of the core 6, it offers the least possible Diameter in its the shaft 1 projecting farthest area a flawless Fastening and contacting area 7 for one end of the spiral spring 3, the the other end is attached to the outer housing part 5 at 8.
