Bush assembly

摘要

A bush assembly is seated in a housing, having an outer sleeve ( 10 ), an inner tube ( 12 ) and a resilient body ( 14 ) connecting the inner tube ( 12 ) and the outer sleeve ( 10 ). The outer sleeve ( 10 ) has projections ( 20 ) from its outer surface that abut the inner surface of the housing ( 40 ) and cause local deformations on the sleeve around the projections ( 20 ). The local deformations around the projections ( 20 ) cause the radial gap ( 16 ) between the inner tube ( 12 ) and the outer sleeve ( 10 ) to change circumferentially and thus bush has different radial stiffness in different directions.
