Abstract: An elastic support mount for use between an outer member having an inner surface formed generally as a surface of revolution and an inner member in the outer member and having an outer surface formed generally as a surface of revolution comprises a solid (circumferentially continuous) elastomeric body of revolution having an outer surface directly engageable against the inner surface of the outer member and an inner surface directly engageable against the outer surface of the inner member. This body has at least one axially open end and is provided at this end with an inner metal sleeve and a coaxial outer metal sleeve which are imbedded in the elastomeric body at the open end and have axial lengths equal to a fraction of the overall length of the elastomeric body. In use this mount is axially compressed by snap rings or the like engaging only against the inner and outer rings so that it is forced into very tight frictional contact with the surfaces of the members between which it is mounted.

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.
