  • the response indicator 35 is formed as a sheet-metal strip at the transition point between the deformation tube 23 and the buffer sleeve 21. As soon as the deformation tube 23 has also pushed on the buffer sleeve 21 only slightly, this is indicated on the basis of the response indicator 35, since it deforms or flakes off accordingly.
  • a difference is to be seen in the fact that in Fig. 24 illustrated clamping sleeve 22, which is used in the exemplary embodiment of the shock absorber 1 according to the invention, the pin openings 5 'in comparison to the illustration in Fig. 11 are arranged rotated.

  • the response indicator 35 is formed as a sheet-metal strip at the transition point between the deformation tube 23 and the buffer sleeve 21. As soon as the deformation tube 23 only partially on the buffer sleeve 21 has pushed, this is indicated by the response indicator 35, since this deforms accordingly or flakes off.
  • the individual components of the shock absorber 1 are formed from materials which are optimized in terms of weight.
  • the buffer sleeve 21, the deformation tube 23, the clamping sleeve 22 and / or the plunger sleeve 11 are formed from a lightweight material / is.
  • a lightweight material is in particular aluminum, an aluminum alloy or a fiber composite material in question. It is of course conceivable that the aforementioned components of the shock absorber 1 from different materials (in particular lightweight materials) are formed.
