Description
Tachometer Es ist bereits eine Hülle für Seilzüge und biegsame Wellen bekannt, die zur Übertragung von Kräften und Bewegungen z. B. bei Fahrzeugbremsen und auch bei Geschwindigkeitsmesserantrieben Anwendung finden und bei denen die Hülle aus einem Faserstoff oder Drahtgewebe oder aus einem Metallschlauch besteht, der innen mit einer weichen Kunststoffmasse ausgekleidet ist. Die Herstellung einer derartigen Hülle bereitet Schwierigkeiten, da es nicht ohne weiteres möglich ist, die Innenwand des Metallschlauches mit dem Kunststoffüberzug zu versehen.Speedometer It is already a cover for cables and flexible shafts known to be used for the transmission of forces and movements z. B. in vehicle brakes and are also used in speedometer drives and where the The cover consists of a fiber material or wire mesh or a metal tube, which is lined inside with a soft plastic compound. Making a such a shell causes difficulties because it is not easily possible to provide the inner wall of the metal hose with the plastic coating.
Es ist weiterhin bekannt, den Metallschlauch biegsamer Wellen zum Antrieb von Tachometern von Fahrzeugen mit einem Gummischlauch oder einem Kunststoffschlauchüberzug zu versehen. Dieser Überzugsschlauch liegt auf der Außenseite des Metallschlauches und dient dazu, das Eindringen von Wasser oder Schmutz in das Schlauchinnere zu verhindern. Zur Herstellung eines Kunststoffschlauchüberzuges ist es auch bekannt, diesen aus zwei Kunststoffschläuchen zu bilden, von denen der erste kürzer als die zu überziehende Welle ist, während der zweite einen größeren Durchmesser hat und so lang ist, daß er auch die frei gebliebene Länge des Metallschlauches bedeckt. Dabei wird der zweite Schlauch durch Aufschrumpfen, vorzugsweise unter Wärmeeinwirkung, festgelegt.It is also known to use flexible shafts for flexible metal tubing Driving speedometers in vehicles with a rubber hose or a plastic hose cover to provide. This cover hose lies on the outside of the metal hose and serves to prevent water or dirt from penetrating the interior of the hose impede. To produce a plastic hose cover, it is also known to form this from two plastic tubes, the first of which is shorter than the is to be coated shaft, while the second has a larger diameter and is so long that it also covers the remaining length of the metal tube. The second hose is shrunk on, preferably under the action of heat, set.
Es ist weiterhin eine biegsame Welle aus einem durch Schraubendraht und Umhüllungsschlauch gestützten Seil bekannt, bei dem dieses aus Tierdarm besteht. Dabei bildet das Seil aus Tierdarm die umlaufende Welle, während die Hülle aus Schraubendraht und der diese umgebende Umhüllungsschlauch ortsfest sind. Der Umhüllungsschlauch kann aus Faserstoff, Gummi od. dgl. bestehen. Diese Welle hat den Nachteil, daß sie einem längeren Betrieb nicht standhält.It is still a flexible shaft made from a screw wire and sheath-supported rope are known, in which this consists of animal intestines. The rope made from animal intestines forms the circumferential shaft, while the sheath is made from screw wire and the surrounding hose are stationary. The wrapping tube Can be made of fiber, rubber or the like. This wave has the disadvantage that it cannot withstand prolonged operation.
Die Erfindung betrifft eine Tachometerwelle mit einem aus Metall gebildeten Wellenschlauch. Die Erfindung besteht darin, daß die aus Metall bestehende Welle mit einem Kunststoffüberzug, vorzugsweise in Form eines Schlauches, versehen ist. Der Kunststoff ist dabei zweckmäßig öl- und benzinfest sowie temperaturbeständig und abriebfest. Er hat den Vorteil, daß die Welle nicht verschleißt und daß sie auch bei längerem Gebrauch nicht bricht. Überraschenderweise hat sich gezeigt, daß bei dem Lauf der mit einem Kunststoffüberzug versehenen Welle der Kunststoffüberzug genügend hält und daß die auftretende Reibung zwischen der Welle und dem Wellenschlauch so gering ist, daß sie vernachlässigt werden kann und daß sich kein Abrieb bildet. Die Enden der Metallwelle werden zweckmäßig mit aus Kunststoff oder Metall bestehenden Bundbuchsen versehen. Die Enden des Wellenschlauches können ebenfalls zweckmäßig mit aus Metall oder Kunststoff bestehenden Bundhülsen versehen sein.The invention relates to a speedometer shaft with one formed from metal Corrugated hose. The invention consists in that the shaft made of metal is provided with a plastic coating, preferably in the form of a hose. The plastic is expediently resistant to oil and petrol and is temperature-resistant and abrasion resistant. It has the advantage that the shaft does not wear out and that they does not break even with prolonged use. Surprisingly, it has been shown that the plastic coating during the course of the shaft provided with a plastic coating holds enough and that the friction that occurs between the shaft and the corrugated hose is so small that it can be neglected and that no abrasion forms. The ends of the metal shaft are expediently made of plastic or metal Provided flange bushings. The ends of the corrugated hose can also be useful be provided with collar sleeves made of metal or plastic.
In der Zeichnung ist eine Ausführungsform der Erfindung schematisch im Schnitt dargestellt.An embodiment of the invention is shown schematically in the drawing shown in section.
Die Tachometerwelle 3 ist ähnlich einer Spiralfeder ausgebildet. Sie endet an beiden Enden in den Vierkanten 3 a und 3 b. Die Welle 3 ist mit einem Kunststoffüberzug 12 versehen und liegt innerhalb des aus Metall gebildeten Wellenschlauches 13. Die Welle trägt an ihren beiden Enden aus Metall oder Kunststoff bestehende Bundbuchsen 14. Diesen entsprechen die Bundhülsen 15, die mit dem Metallschlauch verbunden sind und die ebenfalls aus Metall oder aus Kunststoff bestehen können.The speedometer shaft 3 is designed similar to a spiral spring. she ends at both ends in the squares 3 a and 3 b. The shaft 3 has a plastic coating 12 provided and is located within the corrugated tube 13 formed of metal Shaft carries flange bushings made of metal or plastic at both ends 14. These correspond to the collar sleeves 15, which are connected to the metal hose and which can also be made of metal or plastic.
