Abstract

The device has sprung boot holder elements, and a piston and cylinder unit as hydraulic shock absorber. The absorber (5) contains a hydraulic medium, which is paste-like when at rest. Flexible seals increase the chamber volume, to compensate for temperature-related volume variations of hydraulic medium or hydraulic chambers. The spring device for the boot holder has a setting screw. This is formed by a threaded cylinder part (5') of the shock absorber, with outer thread for a fixed spring abutment (7). The piston rod (5") is coupled to the movable spring abutment (8).

Description

Die Erfindung betrifft ein Schuhhalteraggregat einer Ski- oder Snowboardbindung mit durch Federung nachgiebig gehaltertem Schuhhalterelement sowie parallel zur Federung angeordnetem hydraulischen Stoßdämpfer in Form eines Kolben-Zylinder-Aggregates.The invention relates to a shoe holder assembly of a ski or snowboard binding with a shoe holder element which is flexibly held by suspension and a hydraulic shock absorber arranged parallel to the suspension in the form of a piston-cylinder unit.

Ein derartiges Schuhhalteraggregat einer Skibindung ist Gegenstand der DE 37 43 966 C2. Nach dieser Druckschrift ist ein mit auslösbaren Schuhhalterelementen gekoppeltes Federwiderlager zusätzlich mit einem Ende eines parallel zur Schraubendruckfeder angeordneten hydraulischen Stoßdämpfers verbunden. Das andere Widerlager der Feder wird durch einen normalerweise an einem stationären Gehäuseteil abgestützten Arm eines um eine gehäusefeste Achse schwenkbaren Hebels gebildet, dessen anderer Arm mit dem anderen Ende des Stoßdämpfers verbunden ist. Wenn stoßartige Kräfte auf die Schuhhalterelemente einwirken, wird das erstgenannte Federwiderlager stoßartig bewegt. Dies hat zur Folge, daß der Stoßdämpfer einen Stoß auf den doppelarmigen Hebel ausübt, wodurch dieser zunächst entgegen der Kraft der Schraubendruckfeder geschwenkt wird und die Spannung der Schraubendruckfeder vorübergehend deutlich erhöht. Erst mit einer gewissen Verzögerung wird die Nachgiebigkeit des Stoßdämpfers wirksam, so daß der doppelarmige Hebel zurückschwenken und sich mit seinem die Schraubendruckfeder abstützenden Arm wieder an das stationäre Gehäuseelement anlegen kann.Such a shoe holder assembly of a ski binding is the subject of DE 37 43 966 C2. According to this document, a spring abutment coupled to triggerable shoe holder elements is additionally connected to one end of a hydraulic shock absorber arranged parallel to the helical compression spring. The other abutment of the spring is formed by an arm, which is normally supported on a stationary housing part, of a lever which can be pivoted about an axis fixed to the housing, the other arm of which is connected to the other end of the shock absorber. When sudden forces on the Acting shoe holder elements, the first-mentioned spring abutment is moved suddenly. This has the consequence that the shock absorber exerts a shock on the double-armed lever, whereby this is initially pivoted against the force of the helical compression spring and temporarily significantly increases the tension of the helical compression spring. Only after a certain delay does the resilience of the shock absorber take effect, so that the double-armed lever can pivot back and rest on the stationary housing element with its arm supporting the helical compression spring.

Aus der DE 39 35 551 A1 ist eine funktional ähnliche Bindung bekannt, bei der der Stoßdämpfer gleichachsig zur Schraubendruckfeder innerhalb der Federwindungen angeordnet ist.DE 39 35 551 A1 discloses a functionally similar binding in which the shock absorber is arranged coaxially with the helical compression spring within the spring windings.

Bislang haben sich Skibindungen, bei denen Schuhhalterelemente mit hydraulischen Stoßdämpfern gekoppelt sind, nicht durchsetzen können.So far, ski bindings in which shoe holder elements are coupled with hydraulic shock absorbers have not been able to establish themselves.

Dies dürfte in erster Linie darauf beruhen, daß als Kolben-Zylinder-Aggregate ausgebildete Stoßdämpfer bei überlangen Nichtgebrauchsphasen verhältnismäßig leicht undicht und damit weitestgehend unbrauchbar werden. Ski werden in Regel nur während einer kurzen Zeitspanne des Jahres benutzt. Überwiegend stehen Ski in irgendwelchen Abstellräumen, wobei sie oftmals extremen Temperaturen ausgesetzt sind. Entsprechendes gilt für die auf dem Ski montierten Bindungen.This should primarily be based on the fact that shock absorbers designed as piston-cylinder units leak relatively easily during prolonged periods of non-use and are therefore largely unusable. Skis are usually only used for a short period of the year. Most of the skis are in any storage room, although they are often exposed to extreme temperatures. The same applies to the bindings mounted on the ski.

Aufgabe der Erfindung ist es deshalb, ein neues Konzept für Skibindungen u.dgl. mit den Schuhhalterelemtenten zugeordneten hydraulischen Stoßdämpfern aufzuzeigen.The object of the invention is therefore to develop a new concept for ski bindings and the like. with hydraulic shock absorbers assigned to the shoe holder elements.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Stoßdämpfer ein im Ruhezustand pastöses Hydraulikmedium enthält.This object is achieved in that the shock absorber contains a pasty hydraulic medium in the idle state.

Die Erfindung beruht auf dem allgemeinen Gedanken, Hydraulikmedien einzusetzen, die keinerlei bzw. praktisch keine Kriechneigung aufweisen und damit an den Dichtungen des Stoßdämpfers auch bei langen Ruhephasen nicht austreten können. Dabei nutzt die Erfindung die Tatsache, daß Stoßdämpfer auch mit im Ruhezustand pastösen Hydraulikmedien zufriedenstellend arbeiten können, wenn die bei Hüben des Stoßdämpfers vom Hydraulikmedium zu durchsetzenden Drosselwege entsprechend bemessen sind. Pastöse Hydraulikmedien sind an sich für den Einsatz bei extrem hohen Umgebungstemperaturen vorgesehen. Aufgrund ihrer pastösen Konsistenz haben diese Hydraulikmedien eine geringe Verdampfungsneigung und dementsprechend bleiben auch bei hoher Umgebungstemperatur eventuelle Verdampfungsverluste wünschenswert gering. Bei der Erfindung wird nun die Erkenntnis genutzt, daß diese Medien bei fehlender äußerer Krafteinwirkung ohne Fließ- und Kriechneigung sind. Außerdem hat sich gezeigt, daß diese Medien überraschenderweise auch bei tiefen Temperaturen bei Belastung hinreichend fließfähig sind.The invention is based on the general idea of using hydraulic media which have no or practically no tendency to creep and thus cannot escape from the seals of the shock absorber even during long periods of rest. The invention makes use of the fact that shock absorbers can also work satisfactorily with hydraulic media which are pasty in the idle state if the throttle paths to be penetrated by the hydraulic medium during strokes of the shock absorber are dimensioned accordingly. Pasty hydraulic media are intended for use in extremely high ambient temperatures. Because of their pasty consistency, these hydraulic media have a low tendency to evaporation and accordingly, even at high ambient temperatures, any evaporation losses remain desirably low. In the invention, the knowledge is now used that these media are without tendency to flow and creep in the absence of external force. It has also been shown that this media Surprisingly, are sufficiently flowable even at low temperatures under load.

Gemäß einer bevorzugten Ausgestaltung der Erfindung ist vorgesehen, den Stoßdämpfer als Gleichlaufaggregat auszubilden, d.h. die vom Hydraulikmedium ausgefüllten Kammern des Stoßdämpfers, zwischen denen das Hydraulikmedium bei Stoßdämpferhüben über Drosselwege ausgetauscht wird, haben unabhängig von der Hubstellung des Stoßdämpfers gleichbleibendes Volumen. Damit wird gewährleistet, daß auch in langen Ruhephasen auf das Hydraulikmedium keine nennenswerte Druckkräfte einwirken können, welche das Hydraulikmedium durch die Dichtungen hindurchzutreiben suchen.According to a preferred embodiment of the invention, the shock absorber is designed as a synchronous unit, i.e. The chambers of the shock absorber filled by the hydraulic medium, between which the hydraulic medium is exchanged during shock absorber strokes via throttle paths, have a constant volume regardless of the stroke position of the shock absorber. This ensures that, even in long periods of rest, no significant compressive forces can act on the hydraulic medium, which seek to drive the hydraulic medium through the seals.

Soweit aufgrund von Temperaturschwankungen der Umgebung mit ungleichen Änderungen der Volumina der Hydraulikkammern einerseits und des Hydraulikmediums andererseits gerechnet werden muß, kann in zweckmäßiger Ausgestaltung der Erfindung vorgesehen sein, durch unter Vergrößerung des Kammervolumens nachgiebige Dichtungen für einen entsprechenden Ausgleich zu sorgen.As far as unequal changes in the volumes of the hydraulic chambers on the one hand and the hydraulic medium on the other hand must be expected due to temperature fluctuations in the environment, it can be provided in an expedient embodiment of the invention to provide a corresponding compensation by enlarging the chamber volume through seals.

Des weiteren betrifft die Erfindung ein Federaggregat, welches inbesondere als Teil eines Schuhhalteraggregates der eingangs angegebenen Art angeordnet ist und zur Erzeugung einer Rückstell- bzw. Auslösekraft einer Skibindung dienen kann, mit einer Schraubendruckfeder, einem an deren einem Ende angeordneten beweglichen Federwiderlager und einem am anderen Ende der Feder angeordneten, mittels einer zur Schraubenfederachse gleichachsigen Einstellschraube axial verstellbaren festen Widerlager, welches an einem die Einstellschraube lagernden und axial gegen die Druckkraft der Schraubendruckfeder abstützenden Gehäuse undrehbar und axial beweglich abgestützt bzw. gehaltert ist.Furthermore, the invention relates to a spring assembly, which is arranged in particular as part of a shoe holder assembly of the type specified at the outset and can be used to generate a restoring or release force of a ski binding, with a helical compression spring, one at the other Movable spring abutment arranged at the end and a fixed abutment arranged at the other end of the spring, axially adjustable by means of an adjusting screw coaxial with the helical spring axis, which is non-rotatably and axially movably supported and supported on a housing supporting the adjusting screw and axially supporting against the compressive force of the helical compression spring.

Zur Integration eines hydraulischen Stoßdämpfers in ein derartiges Federaggregat ist erfindungsgemäß vorgesehen, die Einstellschraube als mit Außengewinde für das feste Federwiderlager versehenes Zylinderteil des als Kolben-Zylinder-Aggregat ausgebildeten hydraulischen Stoßdämpfers mit einer an das bewegliche Federwiderlager gekuppelten Kolbenstange auszubilden.In order to integrate a hydraulic shock absorber into such a spring unit, the invention provides for the adjusting screw to be designed as a cylinder part, provided with an external thread for the fixed spring abutment, of the hydraulic shock absorber designed as a piston-cylinder unit with a piston rod coupled to the movable spring abutment.

Hier wird der allgemeine Gedanke verwirklicht, die bisher übliche Einstellschraube durch den Zylinder des Stoßdämpfers zu ersetzen und dazu den Zylinder mit einem Außengewinde zu versehen. Bei dieser Bauweise ergibt sich eine Parallelanordnung von Schraubendruckfeder und Stoßdämpfer ohne Rückwirkung des Stoßdämpfers auf die Federspannung bei stoßartiger Krafteinwirkung auf das bewegliche Federwiderlager. Dementsprechend wirken Feder und Stoßdämpfer in gut reproduzierbarer Weise zusammen, wobei der Stoßdämpfer dynamische Kraftspitzen aufnimmt und die Feder ausschließlich entsprechend dem Widerstand bemessen sein kann, welcher einer langsamen Bewegung des beweglichen Federwiderlagers - im Falle einer Skibindung also der bei einem

langsamen" Sturz des Skifahrers wünschenswerte Auslösewiderstand - entgegenwirken soll.Here the general idea is realized to replace the previously common adjusting screw with the cylinder of the shock absorber and to provide the cylinder with an external thread. This design results in a parallel arrangement of the helical compression spring and the shock absorber without the shock absorber reacting to the spring tension with the impact of a force acting on the movable spring abutment. Accordingly, the spring and the shock absorber work together in a reproducible manner, the shock absorber absorbing dynamic force peaks and the spring can only be dimensioned according to the resistance, which is a slow one Movement of the movable spring abutment - in the case of a ski binding, that of one
Figure imgb0001
slow "fall of the skier desirable trigger resistance - to counteract.

Im übrigen kann der Stoßdämpfer zusätzlich die Funktion der Halterung des beweglichen Federwiderlagers übernehmen, wobei der maximale Hub dieses Federwiderlagers zwangsläufig dem maximalen Hub des Kolbens des Stoßdämpfers angepaßt ist.In addition, the shock absorber can also take over the function of holding the movable spring abutment, the maximum stroke of this spring abutment being inevitably adapted to the maximum stroke of the piston of the shock absorber.

Vorteilhaft ist, daß eine Verstellung des festen Federwiderlagers zu keinerlei Veränderung des möglichen Hubweges des Stoßdämpfers führt.It is advantageous that an adjustment of the fixed spring abutment does not lead to any change in the possible stroke of the shock absorber.

Hinsichtlich weiterer bevorzugter Merkmale der Erfindung wird auf die Ansprüche sowie die nachfolgende Erläuterung der Zeichnung verwiesen, anhand der eine besonders vorteilhafte Ausführungsform beschrieben wird.With regard to further preferred features of the invention, reference is made to the claims and the following explanation of the drawing, on the basis of which a particularly advantageous embodiment is described.

Wie insbesondere die Fig. 1 zeigt, besitzt das dargestellte Federaggregat ein Gehäuse 1 mit zwei über eine Stirnwand U-förmig verbundenen Längsseitenwänden, die an ihren von der Stirnwand abgewandten Endbereichen nach schräg außen abgewinkelt und mit nach einwärts gerichteten Flanschen 2 versehen sind, welche sich in einer zu den Längsseitenwänden senkrechten Ebene erstrecken und jeweils eine im dargestellten Beispiel ovale Öffnung 3 zur Aufnahme von nur in Fig. 7 dargestellten Stiften 4 aufweisen.As shown in FIG. 1 in particular, the spring unit shown has a housing 1 with two longitudinal side walls connected in a U-shaped manner via an end wall, which are angled outward at their end regions facing away from the end wall and are provided with inwardly directed flanges 2, which are extend in a plane perpendicular to the longitudinal side walls and each have an oval opening 3 in the example shown for receiving pins 4 only shown in FIG. 7.

Die Stirnwand des Gehäuses besitzt eine zentrale Öffnung, durch die ein mit stirnseitigen Kreuzschlitzen versehenes Ende eines Zylinders 5' eines als Kolben-Zylinder-Aggregat ausgebildeten hydraulischen Stoßdämpfers 5 hindurchragt. Am Zylinder des Stoßdämpfers 5 ist ein Flansch 6 angeformt, mit dem sich der Zylinder 5' des Stoßdämpfers 5 auf der Innenseite der Gehäusestirnwand axial abstützt. An den Flansch 6 schließt sich auf dem Zylinder 5' des Stoßdämpfers 5 ein Außengewinde an, auf dem ein nach Art einer Mutter axial schraubverstellbares Federwiderlager 7 angeordnet ist. Dieses Federwiderlager wird im dargestellten Beispiel durch ein plattenähnliches Teil gebildet, welches mit Schultern 7' (vgl. Fig. 1) an Längsseitenränder der Längswände des Gehäuses 1 axial geführt und damit relativ zum Gehäuse 1 undrehbar gehalten wird. Die Kolbenstange 5'' des Stoßdämpfers 5 haltert ein weiteres Federwiderlager 8, dessen Form einem Stempel ähnelt. Zwischen den Federwiderlagern 7 und 8 ist eine zum Stoßdämpfer 5 konzentrische Schraubendruckfeder 9 eingespannt.The end wall of the housing has a central opening through which an end of a cylinder 5 ′, provided with end cross-slits, of a hydraulic shock absorber 5 designed as a piston-cylinder unit projects. A flange 6 is formed on the cylinder of the shock absorber 5, with which the cylinder 5 'of the shock absorber 5 is axially supported on the inside of the housing end wall. On the flange 6 an external thread follows on the cylinder 5 'of the shock absorber 5, on which a spring abutment 7 which is axially screw-adjustable in the manner of a nut is arranged. This spring abutment is formed in the example shown by a plate-like part which is axially guided with shoulders 7 '(see FIG. 1) on the longitudinal side edges of the longitudinal walls of the housing 1 and is thus held non-rotatably relative to the housing 1. The piston rod 5 ″ of the shock absorber 5 holds a further spring abutment 8, the shape of which resembles a stamp. A helical compression spring 9, which is concentric with the shock absorber 5, is clamped between the spring abutments 7 and 8.

Diese Schraubendruckfeder 9 spannt das Federwiderlager 8 gegen ein in der Ansicht der Fig. 3 T-förmige Ende eines Kipphebels 10, der mit zwei hakenförmigen seitlichen Fortsätzen 10' (vgl. Fig. 3) versehen ist, die die Stifte 4 auf deren dem Federwiderlager 8 zugewandter Seite umgreifen, wenn der Kipphebel 10 seine Normallage gemäß den Fig. 1 bis 5 einnimmt.This helical compression spring 9 tensions the spring abutment 8 against a T-shaped end of a rocker arm 10 in the view in FIG. 3, which is provided with two hook-shaped lateral extensions 10 '(see FIG. 3) which hold the pins 4 on their spring abutment 8 engage around the side when the rocker arm 10 assumes its normal position according to FIGS. 1 to 5.

Der Kipphebel 10 wird in einem stirnseitigen Schlitz 11 des stempelartigen Federwiderslagers 8 aufgenommen, d.h. das Federwiderlager 8 überlappt den Kipphebel 10 auf seiner in Fig. 1 sichtbaren Oberseite mit einem Fortsatz 8' und auf der in Fig. 5 sichtbaren Unterseite mit einem Fortsatz 8''. Diese Fortsätze 8' und 8'' sind ihrerseits mit miteinander fluchtenden Längsschlitzen 12 versehen, die nur auf ihren einander zugewandten bzw. dem Kipphebel 10 zugewandten Seiten sowie an ihren in Richtung des freien Endes des Kipphebels 10 weisenden Enden offen sind. Die Längsschlitze 12 nehmen einen Bolzen 13 auf, der eine entsprechende Öffnung im Kipphebel 10 zwischen dessen Fortsätzen 10' durchsetzt. Durch diese Bolzen 13 wird eine scharnierartige Gelenkverbindung zwischen dem Federwiderlager 8 und dem Kipphebel 10 mit zu den Stiften 4 paralleler Gelenkachse gebildet.The rocker arm 10 is received in an end slot 11 of the stamp-like spring abutment 8, ie the spring abutment 8 overlaps the rocker arm 10 with an extension 8 'on its upper side which is visible in FIG. 1 and with an extension 8' on the underside which is visible in FIG. 5. '. These extensions 8 'and 8''are in turn together aligned longitudinal slots 12 are provided, which are only open on their mutually facing or the rocker arm 10 facing sides and at their ends pointing in the direction of the free end of the rocker arm 10. The longitudinal slots 12 receive a bolt 13 which passes through a corresponding opening in the rocker arm 10 between its extensions 10 '. These bolts 13 form a hinge-like articulated connection between the spring abutment 8 and the rocker arm 10 with an articulated axis parallel to the pins 4.

Die in den Fig. 1 bis 6 dargestellte Anordnung funktioniert wie folgt:The arrangement shown in Figures 1 to 6 works as follows:

Die über das Federwiderlager 8 sowie den Zylinder 5' des Stoßdämpfers 5 und den Flansch 6 an der Stirnwand des Gehäuses 1 abgestützte Schraubendruckfeder 9 spannt das Federwiderlager 8 gegen den Bolzen 13 und drängt damit den Kipphebel 10 mit seinen hakenartigen Fortsätzen 10' in Eingriff mit den Stiften 4. Die Federspannung der Schraubendruckfeder 9 kann durch Schraubverstellung des Federwiderlagers 7 auf dem Zylinder 5' des Stoßdämpfers 5 verändert werden. Dazu wird der Zylinder 5' des Stoßdämpfers 5 durch Eingriff mit einem Werkzeug in die Kreuzschlitze an dem aus der Stirnwand des Gehäuses 1 herausragenden Ende des Zylinders 5' entsprechend gedreht. Wirkt auf den Kipphebel 10 eine Seitenkraft bzw. ein Drehmoment, welches zu einer Schwenkung des Kipphebels 10 um einen der Stifte 4 führt, so wird das Federwiderlager 8 gegen die Kraft der Schraubendruckfeder 9 sowie gegen den Widerstand des dazu parallel wirkenden Stoßdämpfers 5 in Richtung des Federwiderlagers 7 verschoben. Dabei wird der Widerstand des Stoßdämpfers 5 um so wirksamer, je stoßartiger, d.h. je schneller die Schwenkbewegung des Kipphebels 10 erfolgt. Dies bedeutet, daß starke dynamische Kraftspitzen in erster Linie vom Stoßdämpfer aufgenommen werden, während die Schraubendruckfeder 9 einen von der Schwenkgeschwindigkeit des Kipphebels 10 unabhängigen Widerstand sowie eine Rückstellkraft bewirkt.The helical compression spring 9 supported on the spring abutment 8 and the cylinder 5 'of the shock absorber 5 and the flange 6 on the end wall of the housing 1 tensions the spring abutment 8 against the bolt 13 and thus urges the rocker arm 10 with its hook-like extensions 10' into engagement with the Pins 4. The spring tension of the helical compression spring 9 can be changed by screw adjustment of the spring abutment 7 on the cylinder 5 'of the shock absorber 5. For this purpose, the cylinder 5 'of the shock absorber 5 is correspondingly rotated by engagement with a tool in the cross slots on the end of the cylinder 5' protruding from the end wall of the housing 1. If a lateral force or a torque acts on the rocker arm 10, which leads to a pivoting of the rocker arm 10 around one of the pins 4, the spring abutment becomes 8 moved against the force of the helical compression spring 9 and against the resistance of the shock absorber 5 acting in parallel in the direction of the spring abutment 7. The resistance of the shock absorber 5 becomes more effective the more shock-like, ie the faster the pivoting movement of the rocker arm 10 takes place. This means that strong dynamic force peaks are primarily absorbed by the shock absorber, while the helical compression spring 9 causes a resistance independent of the pivoting speed of the rocker arm 10 and a restoring force.

Gemäß Fig. 7 kann das Gehäuse 1 auf einem Ski 14 fest angeordnet sein, beispielsweise mittels der Stifte 4, derart, daß der Stoßdämpfer 5 und die Schraubendruckfeder 9 etwa paparallel zur Skilängsrichtung ausgerichtet sind. Der Kipphebel 10 kann einen Schuhhalter 15 tragen, welcher ein Ende einer Sohle eines Skischuhes in Mittellage von oben und seitwärts umfaßt und den Schuh freigibt, wenn auf den Schuh eine Störkraft einwirkt, die den Schuh unter Verschwenkung des Kipphebels 10 sowie des Schuhhalters 15 hinreichend weit zur Seite drängt.7, the housing 1 can be fixed on a ski 14, for example by means of the pins 4, in such a way that the shock absorber 5 and the helical compression spring 9 are oriented approximately parallel to the longitudinal direction of the ski. The rocker arm 10 can carry a shoe holder 15, which encompasses one end of a sole of a ski shoe in the middle position from above and sideways and releases the shoe when a disturbing force acts on the shoe, which swings the rocker arm 10 and the shoe holder 15 sufficiently far pushes aside.

Der Aufbau des Stoßdämpfers 5 wird nachfolgend anhand der Fig. 7 erläutert. Der Zylinder 5' wird von einer gestuften Axialbohrung 16 durchsetzt, deren in Fig. 7 linkes Ende einen geringen Durchmesser aufweist und deren an einen Mittelbereich mit größerem Durchmesser anschließender rechter Endbereich mit einem Innengewinde versehen ist. Der linke Bereich der Axialbohrung 16 mit dem geringeren Durchmesser nimmt das eine Ende der Kolbenstange 5'' verschiebbar auf, deren anderes Ende eine Zentralbohrung eines in den Gewindeabschnitt der Axialbohrung 16 eingedrehten Bodenteiles 17 durchsetzt. Im mittleren Abschnitt der Axialbohrung 16 werden vom Kolben 18 der Kolbenstange 5'' zwei Kammern 16' und 16'' abgetrennt, die über einen zwischen dem Außenumfang des Kolbens 18 und dem Innenumfang des mittleren Abschnittes der Bohrung 16 freibleibenden Drosselspalt miteinander kommunizieren. Nach außen sind diese beiden Kammern 16' und 16'' abgedichtet, indem der Spalt zwischen dem linken Ende der Kolbenstange 5'' und dem dieses Ende der Kolbenstange 5'' führenden Teil der Axialbohrung 16 durch zwei Dichtringe 19 abgedichtet ist, die in einer Ringnut des vorgenannten Teiles der Kolbenstange 5'' mit gewisser axialer Verschiebbarkeit angeordnet sind. Der Ringspalt zwischen der Zentralbohrung des Bodenteiles 17 und dem diese Bohrung durchsetzenden Teil der Kolbenstange 5'' wird durch einen Dichtring 20 abgesperrt, zu deren Aufnahme das Bodenteil auf seiner dem Kolben 18 zugewandten Seite eine ringstufenartige Erweiterung der Zentralbohrung aufweist. In dieser Erweiterung wird der Dichtring 20 axial durch eine Ringscheibe 21 festgehalten, die axial zwischen dem Bodenteil 17 und der Ringstufe zwischen dem Gewindeabschnitt und dem mittleren Abschnitt der Axialbohrung 16 des Zylinders 5' eingespannt ist. Im übrigen kann der Spalt zwischen dem Bodenteil 17 und der Axialbohrung 16 durch einen Dichtring 22 abgesperrt sein, der in einer ringstufenartigen Vertiefung am Außenrand der äußeren Stirnseite des Bodenteiles 17 aufgenommen ist, und an einem an den Gewindeabschnitt der Axialbohrung 16 axial anschließenden glatten Abschnitt des Innenumfanges dieser Axialbohrung 16 anliegt. Zur axialen Sicherung des Dichtringes 22 können auf der äußeren Stirnseite des Bodenteiles 17 den Dichtring 22 hakenartig umgreifende Vorsprünge vorgesehen sein.The structure of the shock absorber 5 is explained below with reference to FIG. 7. A stepped axial bore 16 passes through the cylinder 5 ', the left end of which in FIG. 7 has a small diameter and the right end region adjoining a central region with a larger diameter is provided with an internal thread. The left region of the axial bore 16 with the smaller diameter slidably receives one end of the piston rod 5 ″, the other end of which passes through a central bore of a bottom part 17 screwed into the threaded section of the axial bore 16. In the middle section of the axial bore 16, two chambers 16 ′ and 16 ″ are separated from the piston 18 of the piston rod 5 ″, which communicate with one another via a throttle gap remaining between the outer circumference of the piston 18 and the inner circumference of the middle section of the bore 16. These two chambers 16 'and 16''are sealed to the outside by the gap between the left end of the piston rod 5''and the part of the axial bore 16 leading this end of the piston rod 5' being sealed by two sealing rings 19 which are in one Annular groove of the aforementioned part of the piston rod 5 '' are arranged with a certain axial displacement. The annular gap between the central bore of the base part 17 and the part of the piston rod 5 ″ passing through this bore is blocked off by a sealing ring 20, for the reception of which the base part has an annular step-like expansion of the central bore on its side facing the piston 18. In this extension, the sealing ring 20 is held axially by an annular disk 21 which is clamped axially between the base part 17 and the annular step between the threaded section and the central section of the axial bore 16 of the cylinder 5 '. Otherwise, the gap between the bottom part 17 and the axial bore 16 be blocked off by a sealing ring 22, which is received in an annular step-like recess on the outer edge of the outer end face of the base part 17, and bears against a smooth section of the inner circumference of this axial bore 16 which axially adjoins the threaded portion of the axial bore 16. To axially secure the sealing ring 22, the sealing ring 22 can be provided with hook-like projections on the outer end face of the base part 17.

Die Kammern 16' und 16'' sind mit einem Hydraulikmedium gefüllt, welche im Ruhezustand pastöse Konsistenz hat, gleichwohl bei Krafteinwirkung gut fließfähig ist. Derartige Medien haben keinerlei Tendenz, im Ruhezustand an Dichtungen hindurchzukriechen. Dies ist deshalb wichtig, weil der Anpreßdruck der Dichtringe 19,20 und 22 bei stillstehendem Stoßdämpfer 5 vergleichsweise gering bleibt und beispielsweise Ski nur während einer sehr kurzen Zeitspanne im Jahr benutzt werden und Bewegungen des Stoßdämpfers 5 dementsprechend selten sind.The chambers 16 'and 16' 'are filled with a hydraulic medium which has a paste-like consistency in the idle state, but is nevertheless flowable when subjected to force. Such media have no tendency to crawl through seals at rest. This is important because the contact pressure of the sealing rings 19, 20 and 22 remains comparatively low when the shock absorber 5 is at a standstill and, for example, skis are only used for a very short period of the year and movements of the shock absorber 5 are accordingly rare.

Da der Stoßdämpfer 5 als Gleichlaufaggregat ausgebildet ist, d.h. daß die Kolbenstange 5'' beidseitig des Kolbens 18 gleichen Querschnitt hat, bleibt das Gesamtvolumen der Kammern 16' und 16'' bei Verschiebungen des Kolbens 18 konstant. Dementsprechend erübrigt sich die Anordnung einer gesonderten Kammer zur Aufnahme von verdrängtem Hydraulikmedium.Since the shock absorber 5 is designed as a synchronous unit, ie that the piston rod 5 ″ has the same cross section on both sides of the piston 18, the total volume of the chambers 16 ′ and 16 ″ remains constant when the piston 18 is displaced. Accordingly, the arrangement of a separate chamber for receiving displaced hydraulic medium is unnecessary.

Soweit durch starke Temperaturänderungen eine ungleiche Veränderung des Volumens des Hydraulikmediums und des Volumens der Kammern 16' und 16'' auftritt, wird durch die Nachgiebigkeit der Dichtringe 19,20 und 22, insbesondere der Dichtringe 19, ein hinreichender Ausgleich geschaffen.Insofar as an uneven change in the volume of the hydraulic medium and the volume of the chambers 16 'and 16' 'occurs due to strong temperature changes, the resilience of the sealing rings 19, 20 and 22, in particular the sealing rings 19, provides sufficient compensation.

Die Kupplung zwischen Kolbenstange 5'' und dem Federwiderlager 8 kann in der aus den Fig. 3 und 4 ersichtlichen Weise lösbar ausgebildet sein. Das dem Federwiderlager 7 zugewandte Ende der Kolbenstange 5'' besitzt eine Ringnut, in die sich ein Federring 23 einklemmen läßt. Im Federwiderlager 8 ist eine stirnseitige Ausnehmung 24 mit U-förmigem Querschnitt und seitlicher sowie stirnseitiger Öffnung angeordnet. In der Wandung der Ausnehmung 24 ist ein Schlitz 25 angeordnet, in den sich der Federring 23 in Querrichtung zur Längsachse der Kolbenstange 5'' einschieben läßt, wenn die Kolbenstange 5'' unter Seitwärtsverschiebung in die Ausnehmung 24 eingeschoben wird.The coupling between the piston rod 5 ″ and the spring abutment 8 can be designed to be detachable in the manner shown in FIGS. 3 and 4. The end of the piston rod 5 ″ facing the spring abutment 7 has an annular groove into which a spring ring 23 can be clamped. In the spring abutment 8 there is an end recess 24 with a U-shaped cross section and a lateral and end opening. A slot 25 is arranged in the wall of the recess 24, into which the spring ring 23 can be inserted in the transverse direction to the longitudinal axis of the piston rod 5 ″ when the piston rod 5 ″ is pushed into the recess 24 with lateral displacement.
