  • Vehicle suspension bushing
    Patent number: 4316643
    Abstract: A vehicle suspension bushing that is constructed of an inner metal member, an outer metal member, and an elastomeric member inserted between the metal members has an improved construction that increases the bushing's axial rate, or resistance to axial deflection, and decreases its radial rate, or resistance to radial deflection. The main features of the improvement are circumferentially extending slots in the outer surface of the elastomeric member, located adjacent each end of the member, and inwardly extending flanges on the ends of the outer member that fit into the slots in the elastomeric member.
