The pressure prevailing in the strut being correlated to the weight of the car body, and at least one emergency spring ( ) supports the car body ( ) against the substructure ( ) in case of a failure of the main suspension ( ). The at least one emergency spring ( ) is biased and maintained in normal operation position (FIGS. ) by a force (F) generated by the pressure (p) prevailing in the strut ( ). The emergency spring ( ) expands from the normal operation position into an emergency operation position (FIG. ) in which it resiliently supports the car body ( ) in case of a failure of the main suspension system ( ).
