Abstract
Bushings and methods of manufacturing bushings to be used in a chassis of a vehicle or the like for damping and absorbing vibrations, oscillations, and noise are provided. In one implementation, a method of manufacturing a bushing includes the steps of positioning a flexible member around a cylindrical outer surface of a rigid inner member having a cylindrical inner surface or solid core and positioning an outer member having a cylindrical inner surface around the flexible member. The method also includes the step of clamping a cylindrical outer surface of the outer member to form an indentation in the cylindrical outer surface of the outer member, thereby deforming the flexible member. This method may be executed to create a bushing having certain axial, radial, and torsional stiffness.
