ABSTRACT:
An elastomeric isolator has an elastomeric body which incorporates an inner structural member and an outer structural member. The elastomeric body includes a shear hub extending between radial flanges or end plates of the inner and outer structural members that undergoes shearing stresses during deflection of the elastomeric isolator. The elastomeric body is bonded to the radial flanges or end plates. The inner structural member includes a radial flange which is axially offset from an axial flange of the outer structural member. The outer structural member includes a radial flange which is axially offset from an axial flange of the inner structural member. With this configuration, excessive stresses on the elastomeric body are avoided during high load movements of the elastomeric isolator.
