Bush assembly
First Claim
Patent Images
1. A bush assembly comprising:
- a sleeve having at least one projection on its outer surface;
a tube within the sleeve, there being a gap between the sleeve and the tube;
a resilient body interconnecting the tube and the sleeve; and
a housing having a bore into which the sleeve is received, the at least one projection abutting the wall of the bore thereby locally deforming the sleeve adjacent said at least one projection such that the radial width of said gap between the sleeve and the tube radially inward of said at least one projection is less than that at at least one other circumferential point of the tube.

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.

7. A method of manufacturing a bush assembly, comprising inserting a bush into a bore in a housing, the bush comprising:
- —
a sleeve having at least one projection on its outer surface;
a tube within the sleeve, there being a gap between the sleeve and the tube;
a resilient body interconnecting the tube and the sleeve; and
a housing having a bore into which the sleeve is received, said at least one projection abutting the wall of the bore thereby locally deforming the sleeve adjacent said at least one projection such that the radial width of said gap between the sleeve and the tube radially inward of said at least one projection is less than said radial width at at least one other circumferential point of the tube. - View Dependent Claims (8)

9. A bush comprising:
-
a sleeve having at least one projection on its outer surface;
a tube within the sleeve, there being a gap between the sleeve and the tube;
a resilient body interconnecting the tube and the sleeve;
whereinradial depression of the at least one projection relative to the rest of the sleeve causes local deformation of the sleeve such that the radial width of the gap between the sleeve and the tube radially inward of said at least one projection is less than the radial width at at least one other circumferential point of the tube. - View Dependent Claims (10, 11, 12, 13, 14)
