ABSTRACT:
A spring element comprises an insert formed of a rigid metallic core having four outwardly directed faces each bonded to a respective side of a respective elastomeric body whose other side is bonded to a respective metallic plate. The insert so formed is compressed and fits in a throughgoing central passage in a rigid metallic casing with each of the metal plates pressing against a respective inwardly directed face of the casing. The insert is symmetrical about a vertical plane and the angle between the upper two bodies can be larger than the angle between the lower two bodies. In addition the metal plates of the upper two bodies may be integrally formed of a single metal strip also constituting a part of the casing and the lower bodies carry metal plates which lie within a seat which can be formed in a motor-vehicle frame element for a very compact assembly.
