Abstract

End mount assemblies include a mounting bracket dimensioned for securement to an end member of a gas spring and damper assembly. The end mount assembly can include an inner mounting element dimensioned for securement to an elongated damping rod of the gas spring and damper assembly. A first plurality of bushing elements can be operatively disposed between the inner mounting element and the mounting bracket. A second plurality of bushing elements can be operatively disposed between the inner mounting element and the end member. Gas spring and a damper assemblies including such an end mount assembly as well as suspension systems and methods of assembly are also included.

Claims24

Dependent claims

A gas spring and damper assembly comprising:

a gas spring including:
a flexible spring member having a longitudinal axis and including a flexible wall extending longitudinally between first and second ends and peripherally about said axis to at least partially define a spring chamber;
a first end member operatively secured to said first end of said flexible spring member such that a substantially fluid-tight seal is formed therebetween;
and,
a second end member disposed in spaced relation to said first end member and operatively secured to said second end of said flexible spring member such that a substantially fluid-tight seal is formed therebetween;
a damper assembly operative to dissipate kinetic energy acting on said gas spring, said damper assembly including a damper housing operatively connected to said second end member and a damper rod assembly operatively engaged with said damper housing for reciprocal motion relative thereto, said damper rod assembly including an elongated damper rod;
and,
an end mount assembly operatively connecting said elongated damper rod and said first end member and permitting said first and second end members to move at least one of laterally and angularly with respect to one another during extension and compression of said gas spring and damper assembly.
