  Schraubenfederaufhängung, insbesondere für federnde Räder. 



   Bei Schraubenfedern, die abwechselnd auf Zug und Druck beansprucht werden, wie dies z. B. bei federnden Rädern der Fall ist, ergibt sich der Nachteil einerseits, dass die Feder einer übermässigen Ausdehnung unterworfen wird, so dass sich bleibende Deformationen ergeben und andererseits, dass bei übermässigem   Zusammendrücken   der Feder die einzelnen Windungen ineinandergeschoben werden, was ein unregelmässiges Arbeiten und BrUche der Feder nach sich zieht. 



   Die vorliegende Erfindung hat den Zweck, die erwähnten Nachteile zu beseitigen 
 EMI1.1 
 ein ineinanderschieben der Federwindungen verhindert. Dies wird dadurch erreicht, dass die beiden Enden der Schraubenfeder um schwach konische Bolzen derart gewunden werden, dass der letzte Gang jedes Federendes in   cne hohikegelartige   Ausdrehung des dazu gehörigen Bolzens lose eingelegt wird. Wird nun die Feder auf Zug beansprucht, so legen sich die verringerten Federwindungen fest um die   konischen   Teile der Bolzen und verhindern dadurch eine weitere Ausdehnung der Feder über die   Elastizitätsgrenze.   



  Wird die Feder dagegen   zusammengedriickt,   so verhindern die flanschartig vorstehenden Teile der Bolzen, welch letztere in diesem Falle als   Führungsbolzen fungieren,   ein Ineinanderschieben der durch den Druck erweiterten Federwindungen. 



   In der   Zeichnung   ist eine beispielsweise Ausführungsform des   Erfindnngsgegenstandes,   wie sie in einem federnden Rade zur Verwendung kommen kann, veranschaulicht ;   tus   sind die schwach konischen   Bolier)   die mit einer hohlkehlenartigen Ausdrehung b versehen sind. In diese Ausdrehungen werden die Endwindungen c der Feder   d lose eingelegt, 80   dass die ganze Feder leicht von Hand achsial verdrehbar ist. Ein Abgleiten der Windungen c ist einerseits durch den vorstehenden Rand des Kegels a, andererseits durch

  Coil spring suspension, especially for spring wheels.



   For coil springs that are alternately subjected to tension and compression, as z. B. is the case with resilient wheels, the disadvantage arises on the one hand that the spring is subjected to excessive expansion, so that permanent deformations result and, on the other hand, that when the spring is excessively compressed, the individual windings are pushed into one another, which causes irregular working and Breaks the spring.



   The present invention aims to overcome the drawbacks mentioned
 EMI1.1
 prevents the spring coils from sliding into one another. This is achieved in that the two ends of the helical spring are wound around slightly conical bolts in such a way that the last gear of each spring end is loosely inserted into a hollow-cone-like recess in the associated bolt. If the spring is now subjected to tensile stress, the reduced spring turns are firmly attached to the conical parts of the bolts and thereby prevent the spring from expanding further beyond the elastic limit.



  If, on the other hand, the spring is compressed, the flange-like protruding parts of the bolts, which in this case act as guide bolts, prevent the spring coils from sliding into one another due to the pressure.



   In the drawing, an example embodiment of the subject of the invention, as it can be used in a resilient wheel, is illustrated; tus are the slightly conical Bolier) which are provided with a fillet-like recess b. The end turns c of the spring d are loosely inserted into these recesses, 80 so that the entire spring can easily be axially rotated by hand. A sliding of the turns c is on the one hand by the protruding edge of the cone a, on the other hand by
 EMI1.2
 
The bolts are also with eyes f or the like.

   Provide fastening parts by means of which they are connected to the relevant wheel parts or other attachment points.

EMI1.4 dass die beiden Federenden um schwach konische Bolzen gewunden sind und mit jeder l'.') dwindung in je eine hohlkehlenartige Ausdrehung eingelegt sind, die einerseits durch den bei Dehnung der Feder von einer Anzahl ihrer Windungen fest umschlossenen Bolzen, andererseits durch einen flanschen artigen, als Auflager für die gepressten Federwindungen dienenden Teller begrenzt wird. **WARNUNG** Ende CLMS Feld Kannt Anfang DESC uberlappen**. EMI1.4 that the two ends of the spring are wound around slightly conical bolts and, with each l '.') d turn, are each inserted into a hollow groove-like recess, which is secured on the one hand by the bolt, which is tightly enclosed by a number of its turns when the spring is stretched, and on the other by a flange as a support for the pressed spring coils serving plate is limited. ** WARNING ** End of CLMS field may overlap beginning of DESC **.
