  • the design with the outer second spring means 304.2 has the particular advantage that they are easy for already existing Can be retrofitted secondary spring stages, without any intervention in the first spring means 304.1 is required.
  • the variation of the second height H2 of the second spring device 304.2 can be accomplished particularly easily, since no intervention in the design of the first spring device 304.1 is required for this.
  • the second spring means 304.2 halfway up again a release layer in the form of a vulcanized metal plate 304.15, whose diameter is selected so that at the inner periphery of the second spring means 304.2 halfway up an annular first stop surface 304.16 is formed.
  • this first stop surface 304.16 abuts against an associated second stop surface 304.17 which is formed on the connecting element 304.3. If this is the case, the lower section 304.18 of the second spring device 304.2 situated below the metal disk 304.15 can no longer follow the transverse deflection.
  • a further transverse deflection can then be made available only by the upper section 304.19 of the second spring device 304.2 located above the metal disk 304.15. This further transverse deflection ends at the latest when the inner surface of the contact element 304.12 abuts the connecting element 304.3.
  • the present invention has been described above by way of example only, in which the second spring means is disposed at the end of the spring assembly which faces the carbody. However, it is understood that in other variants of the invention can also be provided that such a second is additionally or alternatively also provided at the end of the spring assembly, which faces the landing gear. Likewise, it can of course also be provided that the second spring device is provided in the region between the two ends of the spring arrangement, wherein it is then preferably nested at both ends in the manner described with corresponding first spring means.
