Description
Die Erfindung betrifft einen hydraulischen Teleskop-Stoßdämpfer, insbesondere für Fahrzeuge, bei dem die Federungseigenschaften verändert werden können. Innerhalb des Teleskop-Stoßdämpfers ist in bekannter Weise eine den Arbeitszylinder umfassende Haupttragfeder angeordnet, der eine Hilfstragfeder zugeordnet ist.The invention relates to a hydraulic telescopic shock absorber, in particular for vehicles in which the suspension properties can be changed. Within the telescopic shock absorber is in a known manner a comprehensive working cylinder Arranged main suspension spring, which is assigned an auxiliary suspension spring.
Bei den insbesondere bei Fahrzeugen -auftretenden unterschiedlichen Belastungen und den vielfach, durch die Unebenheit der Fahrbahn entstehenden unterschiedlichen Beanspruchungen kommen häufig Federbrüche der Federungen vor, wenn diese unveränderbare Federungseigenschaften besitzen..In the case of the different ones that occur especially in vehicles Loads and the many different caused by the unevenness of the road Stresses often occur when the spring breaks in the suspension when it is unchangeable Have suspension properties.
Man hat daher auf verschiedenen Wegen versucht, die Federung den wechselnden Belastungen anzupassen und sich im allgemeinen einer zusätzlichen Hilfstragfeder bedient.Attempts have therefore been made in various ways to change the suspension Adjust loads and generally use an additional auxiliary suspension spring served.
Nach der Erfindung wird in bekannter Weise ebenfalls eine zusätzliche Hilfstragfeder verwendet, die nur dann zur Wirkung gebracht wird, wenn die Fahrzeugbelastung sich vergrößert.According to the invention is also an additional in a known manner Auxiliary suspension spring is used, which is only brought into effect when the vehicle is loaded enlarges.
Während man bislang die Ein- oder Ausschaltung der zusätzlichen Hilfstragfeder durch gegenseitiges Verdrehen der Schutzrohre .des Dämpfers oder durch Einschaltung besonderer mit Mitnehmern versehener Verstellmittel vornahm, wird erfindungsgemäß eine die Hilfstragfeder aufnehmende zwischen dem inneren und dem äußeren Schutzrohr eingeschaltete, aus zwei konzentrischen an einer Stirnseite miteinander verbundenen Rohren bestehende Halterung vorgesehen, deren innere Rohrwand ein schraubengangförmig ausgebildetes in die Haupttragfeder cinschrau!bbares Wandteil aufweist.While so far one has to switch the additional auxiliary suspension spring on or off by mutually twisting the protective tubes of the damper or by switching on made special adjustment means provided with drivers, is according to the invention an auxiliary spring between the inner and outer protective tubes switched on, consisting of two concentric ones connected to one another at one end Pipes existing bracket provided, the inner pipe wall is a helical has formed into the main suspension spring screwable wall part.
Diese Ausbildung hat den. Vorteil, daß besondere bauliche Veränderungen; abgesehen von der Vergrößerung des Kopfstückes des Dämpfers, nicht erforderlich sind und die Ein- oder Ausschaltung der Hilfstragfeder sehr einfach ist, wobei eine genaue -und vorher festlegbare stufenförmige, Änderung der Federungseigenschaften des Dämpfers erfolgen kann.This training has the. Advantage that special structural changes; apart from the enlargement of the head piece of the damper, not necessary are and the activation or deactivation of the auxiliary spring is very easy, with a precise and previously definable, step-like change in the suspension properties the damper can be done.
Da die Halterung für die Hilfstragfeder entsprechend der Aufnahme der entspannten Feder eine verhältnismäßig große Baulänge erhält, kann dem Verschraubungsbereich der Halterung für die Hilfsdämpferfeder entsprechend das innere Schutzrohr erfindungsgemäß verkürzt ausgebildet werden.As the holder for the auxiliary spring according to the recording the relaxed spring is given a relatively large overall length, the screw connection area the holder for the auxiliary damper spring according to the inner protective tube according to the invention be shortened.
Die Zeichnung zeigt ein Ausführungsbeispiel der Erfindung teils im Schnitt, teils in Ansicht. Zwischen dem äußeren Schutzrohr I und dem inneren Schutzrohr 2 befindet ,sich die Hilfstragfeder 3, die in entspanntem Zustand in dem Bodenstück Ia des äußeren Schutzrohres und in der Halterung 4 gelagert ist. Die Halterung 4 besteht aus einem Doppelwandrohr, dessen innere Rohrwandung 4a einen schraubengangförmigen Wandteil 4b aufweist, mit dem die Halterung in die Haupttragfeder 5 eingeschraubt ist.The drawing shows an embodiment of the invention in part Section, partly in view. Between the outer protective tube I and the inner protective tube 2 is the auxiliary suspension spring 3, which is in the relaxed state in the bottom piece Ia of the outer protective tube and is stored in the holder 4. The bracket 4 consists of a double-walled pipe, the inner pipe wall 4a of which is helical Has wall part 4b with which the holder is screwed into the main suspension spring 5 is.
je nachdem wie weit die Einschraubung erfolgt, wird die Hilfstragfeder 3 mehr oder weniger stark vorgespannt.depending on how far the screwing takes place, the auxiliary spring is 3 pretensioned to a greater or lesser extent.
Durch die lange Ausbildung .der Halterung 4 kann das innere Schutzrohr 2 eine erhebliche bauliche Verkürzung erfahren.Due to the long design .the bracket 4, the inner protective tube 2 experienced a considerable structural shortening.
