Folded Snubber Bushing for Axial and Radial Vibration Isolation

The rubber element is segmented into multiple functional regions including an inner snubber with first ridges, an outer snubber with second ridges, and connecting web portions. This segmentation allows each region to independently handle different vibration modes - the inner snubber for axial vibrations and the outer snubber for radial vibrations, thereby improving vibration isolation effectiveness while maintaining a manageable structural complexity through modular design

The bushing design transitions from traditional single-direction vibration isolation to multi-directional isolation by adding the outer snubber that extends radially outward. The web portions connect the inner and outer snubbers, creating a three-dimensional structure that simultaneously addresses axial and radial vibrations, effectively adding dimensional capability without excessive complexity

The web portion is pre-formed with the folded configuration during the rubber element manufacturing process itself, rather than requiring post-manufacturing assembly steps. The molding process directly creates the folded web structure that connects the inner and outer snubbers, thereby achieving enhanced vibration damping through the folded geometry while avoiding additional manufacturing complexity from separate assembly operations

The folded web portion serves multiple functions simultaneously: it structurally connects the inner and outer snubbers, provides additional vibration damping through its folded geometry, and acts as a reinforcement element. By merging these multiple functions into a single integrated feature, the design achieves superior vibration damping without proportionally increasing manufacturing complexity
