ABSTRACT:
A suspension strut includes a cylinder; a chamber surrounding the cylinder, the chamber being at least partially filled with hardenable material; and a spring collar having a sleeve section which is received in the hardenable material so that said material, in a solid state, transmits a supporting force from the cylinder to the spring collar. The sleeve section has a radial clearance with respect to said cylinder, so that sleeve section can be installed in said chamber at a predetermined angle to said cylinder.
