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 defined by the inner and outer structural members that undergo shearing stresses during deflection of the elastomeric isolator. The inner and outer structural members are designed to provide a travel stop for the elastomeric isolator in order to avoid compression of the shear hub during high loads. The elastomeric bushing can also include an optional integral elastomeric heat shield which protects the shear hub.
Claims10
An isolator comprising:
- a single piece elastomeric body defining a heat shield;
- an outer structural member attached to said elastomeric body;
- an inner structural member attached to said elastomeric body;
- a shear hub extending between said outer structural member and said inner structural member;
- a mounting bore defined by said elastomeric member, said inner structural member surrounding said mounting bore;
- wherein
- said heat shield surrounds said shear hub.
