Abstract

The strut (1) has a damping piston provided with a piston rod (3), and a radial supporting flange (4) fastened at end of the piston rod. Two springs (5, 6) are formed as spiral springs, where opposite ends of the spiral springs are connected with a damping cylinder (2). One of the spiral springs is wound linearly, and the other spiral spring wound progressively. The latter spiral spring is supported with an end that is assigned to the damping cylinder at a spring actuating element (11). The actuating element is adjustable in a direction of a longitudinal axis (9) of the strut.

Description

Die Erfindung bezieht sich auf ein Federbein für ein Fahrzeugrad, insbesondere ein Rad eines Motorrades, wie es im Oberbegriff des Anspruchs 1 beschrieben ist.The The invention relates to a spring strut for a vehicle wheel, in particular a wheel of a motorcycle, as it is in the preamble of Claim 1 is described.

Bei derartigen Federbeinen ist häufig eine Einstellmöglichkeit der Federrate gewünscht. Eine entsprechende Lösung ist hierfür in der NL 1029266 dargestellt. Neben anderen Ausführungen zeigen unter anderem die 10 bis 12 der Vorveröffentlichung ein Federbein mit einer Schraubenfeder und einem dazu in Reihe geschaltetem Elastomerblock. Der Elastomerblock lässt wenigstens auf einem Teil seiner Länge einen Hohlraum zur äußeren Zylinderwand frei, in den er beim Zusammendrücken – durch Einfederungsbewegungen des Federbeins – ausweichen kann. In diesen Hohlraum kann eine konische Stellhülse durch einen geeigneten Verstellmechanismus eingeschoben werden. Dem Elastomerblock wird je nach Eindringtiefe der Stellhülse zunehmend die erwähnte Ausweichmöglichkeit genommen mit der Folge, dass sich seine Federhärte und damit die Gesamtfederrate des Systems erhöht.In such struts is often desired adjustment of the spring rate. A suitable solution for this is in the NL 1029266 shown. Among other remarks, among others, the 10 to 12 the Vorveröffentlichung a strut with a coil spring and a series-connected elastomeric block. The elastomer block leaves free at least on a part of its length a cavity to the outer cylinder wall, in which he can dodge during compression - by compression movements of the shock absorber. In this cavity, a conical adjusting sleeve can be inserted by a suitable adjusting mechanism. Depending on the depth of penetration of the adjusting sleeve, the elastomeric block is increasingly being given the aforementioned possibility of avoidance, with the result that its spring stiffness and thus the overall spring rate of the system are increased.

In einer deutschen Patentanmeldung DE 10 2008 050 682.6 der Anmelderin sieht ein Federbein wenigstens zwei parallel angeordnete Schraubenfedern vor. Eine von diesen Schraubenfedern lässt sich in ihrer Höhenlage kontinuierlich verstellen von einer unteren, abgeschalteten Position bis einer oberen Position, in der sie von Anfang an die Verstellbewegungen des Federbeins mit abfedert. Je nach Höhenlage dieser Schraubenfeder ergeben sich damit unterschiedliche Federratenkennlinien.In a German patent application DE 10 2008 050 682.6 the Applicant provides a strut at least two parallel coil springs before. One of these coil springs can be continuously adjusted in its altitude from a lower, switched-off position to an upper position in which it absorbs from the outset the adjustment movements of the strut with. Depending on the altitude of this coil spring, this results in different spring rate characteristics.

Aufgabe der Erfindung ist es, ein gattungsgemäßes Federbein zu vereinfachen.task The invention is a generic shock absorber to simplify.

Die Aufgabe wird erfindungsgemäß mit den kennzeichnenden Merkmalen des Hauptanspruchs gelöst. Vorteilhafte Ausgestaltungen ergeben sich aus den Unteransprüchen.The Object is according to the invention with the characterizing Characteristics of the main claim solved. Advantageous embodiments emerge from the dependent claims.

Nach der Erfindung wirken die zwei parallel zu einander angeordneten Federelemente bei jeder Einstellung von Anfang gemeinsam. Die unterschiedlichen Federraten stellen sich automatisch ein, da sich bei der progressiv gewickelten Feder mit zunehmendem Einfederungsweg immer mehr Windungen aneinanderlegen, also auf Block gehen.To According to the invention, the two act parallel to one another Spring elements in common with each setting from the beginning. The different ones Spring rates are set automatically, as is progressive wound spring with increasing Einfederungsweg more and more turns together, So go to block.

Bei einer vorteilhaften Ausgestaltung der Erfindung kann darüber hinaus die Federbasis der progressiv gewickelten Feder in ihrer Höhenlage verstellt werden. Damit lassen sich die Federraten noch besser auf die jeweiligen Verhältnisse abstimmen.at an advantageous embodiment of the invention can about In addition, the spring base of the progressively wound spring in their Altitude be adjusted. This allows the spring rates even better on the respective conditions vote.

Insgesamt zeichnet sich das erfindungsgemäße Federbein durch ein geringes Gewicht und einer kontinuierlichen Verstellmöglichkeit der Federrate aus. Im Falle der verstellbaren Federbasis werden die Verstellmöglichkeiten noch erweitert. Dabei sind nur geringe Betätigungskräfte bei der Verstellung der Federbasis erforderlich.All in all is distinguished by the strut of the invention a low weight and a continuous adjustment the spring rate off. In the case of the adjustable spring base, the Adjustments still extended. These are only small Actuating forces in the adjustment of the spring base required.

Weitere vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus der nachfolgenden Beschreibung und der dazu gehörenden Zeichnung. Darin ist in der einzigen Figur schematisch ein erfindungsgemäßes Federbein dargestellt.Further advantageous embodiments of the invention will become apparent from the following description and the accompanying drawing. In this is in the single figure schematically an inventive Strut shown.

Ein Federbein 1 ist Teil einer nicht weiter dargestellten Radaufhängung eines Fahrzeugrades, genauer eines Vorder- oder Hinterrads eines Motorrades.A strut 1 is part of a not further shown suspension of a vehicle wheel, more precisely a front or rear wheel of a motorcycle.

Derartige Federbeine sind allgemein bekannt, so dass sich die Darstellung in der Zeichnung lediglich auf die funktionellen Teile beschränkt.such Struts are well known, so that the appearance limited in the drawing only to the functional parts.

Das Federbein 1 besteht aus einem Dämpfungszylinder 2, in dem ein wegen der Darstellungsart nicht erkennbarer Dämpfungskolben geführt ist. Am Dämpfungskolben greift eine Kolbenstange 3 an, die nach oben aus dem Dämpfungszylinder 2 austritt und an ihrem freien Ende einen Stützflansch 4 trägt, der wiederum als Widerlager für die oberen Enden zweier Schraubenfedern 5 und 6 dient. An seiner von der Kolbenstange 3 abgewandten Oberseite ist am Stützflansch 4 ein Befestigungsauge 7 für eine nicht weiter dargestellte Radführung ausgeformt. Mit einem ähnlichen Befestigungsauge 8 ist gegenüberliegend der Dämpfungszylinder 2 am ebenfalls nicht gezeichneten Fahrzeugaufbau festgelegt.The strut 1 consists of a damping cylinder 2 , in which a due to the Darstellart not recognizable damping piston is performed. At the damping piston engages a piston rod 3 at the top of the damping cylinder 2 outlet and at its free end a support flange 4 carries, in turn, as an abutment for the upper ends of two coil springs 5 and 6 serves. At his from the piston rod 3 facing away from the top is on the support flange 4 a fastening eye 7 formed for a not shown wheel guide. With a similar fastening eye 8th is opposite the damping cylinder 2 set on also not drawn vehicle body.

Die Schraubenfedern 5 und 6 sind als Stahldruckfedern ausgelegt und bilden im Sinne der beanspruchten Erfindung ein erstes und zweites Federelement. Sie sind koaxial um den Dämpfungszylinder 2 angeordnet und mit Abstand ineinander geschachtelt. Ihre gemeinsame Längsachse fällt mit einer Längsachse 9 des Federbeins 1 zusammen. Die äußere Schraubenfeder 5 ist linear, die innere Schraubenfeder 6 progressiv gewickelt. Durch diese progressive Wicklungsart, verringert sich die Steigung pro Windung nach oben – in Richtung des Abstützflansches 4 – zunehmend, so dass sich die letzten Windungen schließlich aneinander.The coil springs 5 and 6 are designed as steel compression springs and form in the sense of the claimed invention, a first and second spring element. They are coaxial with the damping cylinder 2 arranged and nested at a distance. Their common longitudinal axis coincides with a longitudinal axis 9 of the strut 1 together. The outer coil spring 5 is linear, the inner coil spring 6 progressively wrapped. This progressive type of winding reduces the pitch per turn upwards - in the direction of the support flange 4 - increasingly, so that the last turns finally together.

Wie bereits erwähnt, stützen sich die beiden Schraubenfedern 5, 6 mit ihren oberen Enden am Stützflansch 4 ab. Das untere Ende der äußeren Schraubenfeder 5 liegt auf einem radialen Fortsatz 10a auf, der Teil eines topfförmigen runden Aufnahmegehäuses 10 ist. Dieses Aufnahmegehäuse 10 weist neben seinem Fortsatz 10a einen Topfrand 10b und einen Topfboden 10c auf. Des Weiteren ist das Aufnahmegehäuse 10 fest mit dem Boden des Dämpfungszylinders 2 bzw. dem Befestigungsauge 8 verbunden und sein Topfrand 10b umgibt mit radialem Abstand den unteren Abschnitt des äußeren Zylindermantels.As already mentioned, the two coil springs are based 5 . 6 with their upper ends on the support flange 4 from. The lower end of the outer coil spring 5 lies on a radial extension 10a on, the part of a cup-shaped round receiving housing 10 is. This housing 10 points next to his extension 10a a pot edge 10b and a pot bottom 10c on. Furthermore, the receiving housing 10 stuck to the bottom of the damping cylinder 2 or the fastening eye 8th connected and his pot edge 10b surrounds with radial distance the lower portion of the outer cylinder shell.

In dem Ringraum, gebildet durch die Innenseite des Topfrands 10b und der Zylinderaußenseite des Dämpfungszylinders 2, ist höhenverstellbar ein ringförmiges Federstellelement 11 geführt, das heißt, das Federstellelement 11 kann in Richtung der Längsachse 9 des Federbeins 1 verschoben werden. Auf dem Federstellelement 11 liegt das untere Federende der innenliegenden progressiven Schraubenfeder 6. Zwischen der Unterseite des Federverstellelements 11 und der Innenseite des Topfbodens 10c bildet sich eine Hydraulikkammer 12 aus, die über eine Versorgungsleitung 13 im Topfboden 10c mit Hydraulikflüssigkeit gespeist wird.In the annulus, formed by the inside of the pot rim 10b and the cylinder outside of the damping cylinder 2 , Height adjustable is an annular spring actuator 11 guided, that is, the spring actuator 11 can be in the direction of the longitudinal axis 9 of the strut 1 be moved. On the spring actuator 11 is the lower spring end of the internal progressive coil spring 6 , Between the bottom of Federverstellelements 11 and the inside of the pot bottom 10c a hydraulic chamber forms 12 out, over a supply line 13 in the bottom of the pot 10c is supplied with hydraulic fluid.

Je nach Füllmenge hebt oder senkt sich das Federstellelement 11 und drückt die progressive Schraubenfeder 6 zusammen oder entlastet sie. Bei einem Anheben legen sich immer mehr Windungen der Schraubenfedern in Bereichen des oberen Endes an und stehen damit für die Federwirkung nicht mehr zur Verfügung stehen. Die Federrate der Schraubenfeder 6 steigt. Beim Absenken des Federstellelements 11 drehen sich die Verhältnisse um und die Schraubenfeder 6 wird weicher. Die Gesamtfederrate des Systems Federbein, gebildet durch die Addition der einzelnen Federraten der beiden Schraubenfedern 5 und 6, kann auf diese Weise gezielt eingestellt werden.Depending on the capacity, the spring actuator rises or falls 11 and pushes the progressive coil spring 6 together or relieve them. When lifting an increasing number of turns of the coil springs put in areas of the upper end and stand so that the spring effect is no longer available. The spring rate of the coil spring 6 increases. When lowering the spring actuator 11 the conditions turn around and the coil spring 6 gets softer. The total spring rate of the system strut, formed by the addition of the individual spring rates of the two coil springs 5 and 6 , can be targeted in this way.
