Abstract
In order to obtain a particularly soft spring characteristic the rubber spring element consisting of relatively hard material having good mechanical strength is traversed by cavities and hollow channels, which intersect said cavities, in such a manner that the area of the inside cross-section of the hollow channels amounts to at least 25% of the area of the largest inside cross-section of the nearest cavity traversed by this hollow channel, while the hollow channels may directly intersect in the rubber matrix.
