Abstract
An elastomeric tie rod end isolator or an elastomeric cartridge isolator that includes an outer metal sleeve defining a generally cylindrical socket, a generally cylindrical inner metal sleeve disposed coaxially within the socket in radially spaced relationship with the outer metal sleeve, and an elastomeric isolator disposed therebetween. The elastomeric isolator is a unitary annular body formed of an elastomer material and having a radially inboard surface in contact with the inner metal sleeve and a radially outboard surface in contact with the outer metal sleeve. The unitary elastomer body has a generally conical primary load-carrying section and a generally cylindrical secondary load-limiting section, each disposed coaxially about the axis of the socket. The load-limiting section includes a snubber gap formed by an axially extending groove. The annular unitary elastomeric body may be formed of an elastomer material having a relatively low damping characteristic and a relatively soft stiffness characteristic.
