Abstract

The spring unit comprises a hollow cylindrical damping element (i) based on polyisocyanate polyaddition products, with one of its ends constituted as a circumferential lip. The detailed geometry of this damping element is specified by its axial and diametral dimensions, angles and rounding radii. An independent claim is also included for an automobile with spring units.
