Summary:A vehicle wheel suspension system is provided, having a first spring element clamped between the vehicle body and a wheel and a second spring element clamped between the body and the wheel in parallel to the first spring element by application of a tensile force by a tensioning element. The second spring element is not active without application of the tensile force. A pressure addition spring element is also provided which, in the case of large spring excursions, acts as an end stop. The pressure addition spring element is not activated by of the tensile force for activating the second spring element. The spring rate of the second spring element is preferably lower than that of the first spring element. Additional spring elements of different wheels or axles can be activated by a common mechanical tensioning element which can shorten or lengthen several tension devices connected with the spring elements.
