Abstract
Description
Die Erfindung betrifft variabel verlegbare Kraftübertragungs mittel, welches durch einen Mantel (B) aus aneinandergereihten, mit axialen Durchbrüchen (4, 5) versehenen Formstücken (Fig. 1-10) (1-1a; 10; 10.1-11; 11.1; 11.2) besteht und von einen Zugseil (A) durchgriffen werden.The invention relates to power transmission means that can be installed in a variable manner, which by means of a casing (B) is made of strings which are provided with axial openings ( 4, 5 ) ( FIGS. 1-10) ( 1 - 1 a; 10 ; 10.1 - 11 ; 11.1 ; 11.2 ) exists and can be penetrated by a pull rope (A).
Der sogenannte Bowdenzug welcher im wesentlichen aus einen gewendelt geformten Stahldrahtmantel besteht und von einen Zugseil durchführt wird, welches Zugkräfte flexibel ohne Umlenkrollen, Gegenhalter und Stützen übertragen kann, wird bevorzugt am Zweirad für die Bremsbetätigung oder Schaltung verwendet.The so-called Bowden cable which essentially consists of one there is a helically shaped steel wire jacket and one Pull rope is carried out, which tensile forces without flexible Deflection pulleys, counter supports and supports can be transferred preferably on the two-wheeler for braking or switching used.
Der Nachteil dieses Bowdenzuges liegt in seiner gewendelten Stahldrahtbauart. Bei Kurvenverlegung entstehen zwei verschieden gestreckte Längen, welche mittels der federnd gewendelten Stahldrahtbauart durch Spaltbildung am Außenradius ausgeglichen wird. Wird das Zugseil betätigt, kann sich die Gegenkraft nur am Innenradius abstützen was den Bowdenzug in eine gestreckte Position ziehen möchte. Dieses wird verhindert, weil das Zugseil diese Zwangslage gebietet. Die Folge ist ein hoher Reibwider stand. Je stärker am Zugseil gezogen wird, je größer der Reib widerstand, je uneffektiver die Kraftübertragung, was bei Bremsvorgängen sehr nachteilig ist.The disadvantage of this Bowden cable is that it is coiled Steel wire construction. When laying curves, two arise differently stretched lengths, which by means of the spring coiled Steel wire type balanced by gap formation on the outer radius becomes. If the pull rope is operated, the counterforce can only support on the inner radius which leads the Bowden cable into a straight line Position. This is prevented because the pull rope commanded this predicament. The result is a high frictional resistance was standing. The harder the cable is pulled, the greater the friction resisted, the more ineffective the power transmission, which at Braking is very disadvantageous.
Die beim Biegen des Seilzuges einhergehende Längenveränderung, ist so nachteilig, daß sich dieser Bowdenzug kaum für präzise Schaltvorgänge einer Ketten- oder Nabenschaltung eignet. Eine enge Kurvenlegung ist nicht möglich, was eine unnötige Längenzugabe des Bowdenzuges erfordert und damit höhere Kosten verursacht, optisch unvorteilhaft aussieht, lange Wege verursacht und somit kaum eine geordnete Verlegungen zuläßt.The length change associated with the bending of the cable, is so disadvantageous that this Bowden cable is hardly precise Switching processes of a chain or hub gear is suitable. Tight cornering is not possible, which is unnecessary Length addition of the Bowden cable requires and thus higher costs causes, looks optically disadvantageous, causes long distances and thus hardly permits an orderly laying.
Der Erfindung liegt die Aufgabe zugrunde, den Reibwiderstand zu minimieren und den Einsatz dieser flexiblen Kraftübertragungs mittel zu optimieren. Weitere Vorzüge sind die bessere Richtungs stabilität, viel engere und spannungsfreie Kurvenlegung, die Berührungsflächen des Zugseiles um 75% zu reduzieren und Gleithemmnisse zu beseitigen, sowie eine bessere Panzerung und Abdichtung gegen äußere Einflüsse zu erreichen.The invention has for its object the frictional resistance to minimize and use this flexible power transmission to optimize medium. Other advantages are the better direction stability, much tighter and stress-free cornering that Reduce contact areas of the pull rope by 75% and Eliminate sliding obstacles, as well as better armor and To achieve sealing against external influences.
Diese Aufgabe wird erfindungsgemäß durch die kennzeichnenden Merkmale der Ansprüche 1; 6; 16; 23 gelöst, indem die wendelgeformte Stahldrahthülle durch aneinandergereihte Gleithülsen (1) ersetzt wird. Eine axial stirnseitig vorhandene Stützfläche (2) weist eine konvex kugelförmige Krümmung auf, während die gegenüberliegende Fläche eine konkave kugelpfannen förmige Ausnehmung (3) aufweist, welche Formkongruent zur Stützfläche (2) ist. Die Gleithülsen (1) aneinandergereiht, lagern formschlüssig Fläche (2) in Fläche (3), was eine enge reibungsarme Kurvenlegung gestattet, weil die unterschiedlichen Längen durch die Kugelform kompensiert werden. Wenn das Zugseil (A) gezogen wird, preßt sich der Gegenhaltemantel (B) welcher aus den aneinander aufgefädelten Gleithülsen (1) gebildet wird, nicht gegen das Seil (A), was eine Leichtgängigkeit der Kraft übertragung zur Folge hat. Die Hülsen (1) können aus Metall, insbesondere eloxierten Aluminium, aber auch aus Kunststoff sein, weicher vorteilhafterweise im Spritzgießverfahren zu Hülsen (1) geformt wurde, hergestellt sein.This object is achieved by the characterizing features of claims 1; 6; 16; 23 solved by replacing the helically shaped steel wire sleeve by sliding sleeves ( 1 ) lined up in a row. An axially end-side support surface ( 2 ) has a convex spherical curvature, while the opposite surface has a concave ball socket-shaped recess ( 3 ), which is congruent to the support surface ( 2 ). The sliding sleeves ( 1 ) lined up, form-fittingly support surface ( 2 ) in surface ( 3 ), which allows tight, low-friction curves because the different lengths are compensated for by the spherical shape. When the pulling rope (A) is pulled, the counter-holding jacket (B), which is formed from the sliding sleeves ( 1 ) threaded onto each other, does not press against the rope (A), which results in the power transmission being easy to move. The sleeves ( 1 ) can be made of metal, in particular anodized aluminum, but also of plastic, which has advantageously been molded into sleeves ( 1 ) in an injection molding process.
Um die Handhabung der einzelnen Hülsen zu verbessern sollten diese auf einen Schlauch aus gleitfähigen Kunststoff aufgefädelt werden. Dadurch wird ein zusammenhängender Strang gebildet, was handlingsfreundlich und vermarktungstechnisch vorteilhafter ist.In order to improve the handling of the individual sleeves these are threaded onto a tube made of slidable plastic will. This creates a coherent strand which is easy to handle and more technically advantageous is.
Eine weitere Variante der reibungsarmen Kraftumlenkung ist die teilweise Freiverlegung des Zugseiles zwischen Abstützungen, welche an Rahmenteilen befestigt sind. Bei Kraftumlenkungen (Kurvenlegung) wird das Zugseil (A) über anbringbare Kugel- oder Rollenführungen der Kurvensegmente (20; 25) geleitet. Zwei Bauarten können eingesetzt werden. Einmal die Rollenführung (23) oder die Kugelführung (24). Beide Systeme garantieren nur geringen Kraftverlust durch die minimierte Reibung.Another variant of the low-friction power redirection is the partial relocation of the traction cable between supports that are attached to frame parts. In the case of force redirection (cornering), the traction cable (A) is guided over attachable ball or roller guides of the curve segments ( 20 ; 25 ). Two types can be used. First the roller guide ( 23 ) or the ball guide ( 24 ). Both systems guarantee only minimal loss of power due to the minimized friction.
Eine weitere Zugseilverlegung mit minimierten Reibwerten bietet sich durch die diagonal zum Rahmenrohr (25) verlegten Zugseile (A). Dieses kann auch durch Nachrüstung erreicht werden, indem vom Einlaufstück (25.1) bis zum Auslaufstücke (25.2) ein oder mehrere Schlauch/Schläuche (Kunststoff) gegen und am jeweiligen Ende durch Verkleben an den Ausläufen fixiert wird, damit das/die um diagonal das Rohr (25) zu durchqueren, um reib- und kontakt frei das Rohrende mittels Auslaufstückes (25.2) wieder zu verlassen. Dabei werden keine Anlagerflächen mit dem Rohr entstehen. Diese Methode hat den Vorteil, daß weder ein Geräusch-verursachendes Anschlagen des/der Seile(s) (A) am Rahmenrohr (25) erfolgt, noch erhöhte Reibwerte auftreten.The traction cables (A), which are laid diagonally to the frame tube ( 25 ), offer further traction cable laying with minimized friction values. This can also be achieved by retrofitting, from the inlet piece ( 25.1 ) to the outlet pieces ( 25.2 ) one or more hoses / hoses (plastic) are fixed against and at the respective end by gluing to the spouts so that the pipe diagonally Traverse ( 25 ) in order to leave the pipe end again free of friction and contact using the outlet piece ( 25.2 ). There will be no contact surfaces with the pipe. This method has the advantage that the rope (s) (A) does not strike the frame tube ( 25 ), which causes noise, and there are no increased coefficients of friction.
