Abstract

An anti-vibration device including first and second rigid strength members interconnected by an elastomer body, the first strength member includes a base and at least three branches extending from the base along a first direction toward the second strength member, the three branches including two external branches and one central branch. The second strength member includes a transversal portion and at least two branches extending along the first direction from the transversal portion, respectively between the external branches and the central branch of the first strength member. The elastomer body extends transversally to the first direction between the external branches of the first strength member and has four legs extending respectively between the branches of the first strength member and the branches of the second strength member.

Abstract

The invention provides for a radially flexible bushing, comprising an outer annular element, an inner rigid element surrounded by the outer element, an elastomer body, which adherently attaches the inner rigid element and the outer element. The elastomer body comprises spaced-apart arms extending radially from the inner rigid element to the outer element. It further comprises at least one radial stop for limiting the radial displacement of the inner rigid element. The radial stop, which is positioned on the outer element between the arms, comprises an arch having extremities joined to the outer element and a top oriented towards the rigid element. The arch defines together with the outer element a tubular cavity.
