ABSTRACT:
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.
