Title:
TANK RUBBER CUSHION
Document Type and Number:
Japanese Patent JP2012097770
Kind Code:
A
Abstract:

To provide a tank rubber cushion which has a novel structure to achieve sufficiently high support spring rigidity in the vertical direction and a low spring property in the horizontal direction without complicating the structure or increasing parts counts.

Two divided pieces of cylindrical rubber 14 are fitted over an inner axial member 12 which is inserted into an insertion hole 20 of a support portion 18. Each divided piece of cylindrical rubber 14 is provided with an axial vibration damping rubber portion 40 which is interposed between the axially opposed surfaces of a flange portion 38, 28 and the support portion 18, and a tubular axially perpendicular vibration damping rubber portion 42 which is interposed between the axially perpendicular opposed surfaces of the inner axial member 12 and the support portion 18. The axially perpendicular vibration damping rubber portion 42 of each divided piece of cylindrical rubber 14 is provided with circumferentially recessed and projected portions 48, 50 which have partially different diameters along the circumference, so that the outer circumferential surface of the inner axial member 12 and the inner circumferential surface of the support portion 18 are assembled together with gaps 52, 54 present therebetween at the recessed and projected portions 48, 50.
