ABSTRACT:
A clamp assembly includes an annular clamping member for clamping an open end of an elastomeric sleeve of an air spring of a suspension system in a fluid tight relationship with a sealing surface of an end member of the air spring. An annular concave recess is formed in either the end member or clamping member and is in radial alignment with a convex projection formed on the other of the end member or clamping member. The concave recess has an axial length at least equal to or greater than the axial length of the convex projection but not as deep as the height of the convex projection. This provides a pair of pinch areas on opposite sides of the radially aligned centers of concavity of said recess and apex of the projection to sealingly secure the sleeve therebetween without excess squeezing of the sleeve at the radially aligned centers of the recess and projection. The radius of curvature of the convex projection is greater than the radius of curvature of the concave recess by an amount less than the thickness of the elastomeric sleeve.
