ASSEMBLY OF KNUCKLE AND BUSHING

摘要

PROBLEM TO BE SOLVED: To provide a knuckle-bushing assembly having a low-twist and conical rigidity while having a high rigidity in a radial direction and in an axial direction without a complex and/or expensive structure.SOLUTION: A suspension coupling 5 used in a vehicle suspension system has a knuckle-bushing assembly 10. The knuckle member is a cast aluminum piece comprising a passageway which bears a two-piece bushing member 15 including a formed metal inner member 17 and a molded elastomer outer member 16 having an extension member 19 at each end part. The bushing member 15 is press-fitted into the knuckle member 12 and shows a high rigidity in a radial direction (R) and in an axial direction (A) and a low rigidity in a twist direction (T) and in a conical direction (C).
