Abstract
A vibration damper for a motor vehicle includes an inner tube concentrically aligned within an outer housing. A piston shaft having a piston attached at an end thereof is slidably inserted into the inner housing. A support ring encloses the inner housing defining a pumping chamber inside the inner housing. The piston shaft is inserted through the support ring. The support ring includes a seal cover having an inner surface with a rim. A rod guide is inserted into the seal cover and abuts the rim. The rod guide guides the shaft through the support ring and provides lateral support to the shaft. A retainer sleeve is secured to the rod guide having the rim disposed between the rod guide and the retainer sleeve securing the rod guide to the retainer sleeve.
Claims28
A vibration damper assembly comprising:
- an inner housing concentrically aligned within an outer housing;
- a piston shaft having a piston attached at an end thereof and being inserted into said inner housing;
- a support ring enclosing said inner housing thereby defining a pumping chamber within said inner housing, and having said piston shaft inserted therethrough;
- said support ring including:
- a seal cover having an inner surface with a rim;
- a rod guide inserted into said seal cover abutting said rim,
- wherein said rod guide guides said shaft through said support ring;
- a washer secured to said rod guide, wherein said rim is disposed between said rod guide and said washer thereby securing said rod guide to said retainer sleeve.
A vibration damper assembly comprising:
- an inner tube disposed within an outer housing;
- a piston having a shaft slidably aligned within said inner tube with a support ring affixed to said inner tube;
- said support ring including:
- a seal cover having an inner surface defining and inner volume;
- a rod guide inserted into said seal cover, said rod guide having an aperture with said shaft inserted therethrough;
- and
- wherein said rod guide floats inside said seal cover in a lateral direction.
A vibration damper assembly comprising:
- a tube defining a pumping chamber;
- a piston having a shaft slidably aligned within said pumping chamber with a support ring being affixed to said tube;
- said support ring including:
- a seal cover having an inner surface defining and inner volume;
- a rod guide having said shaft inserted therethrough and being inserted into said seal cover;
- a retainer sleeve secured to said rod guide thereby affixing said rod guide to said seal cover;
- and
- wherein said rod guide and said retainer sleeve substantially fill the inner volume of said seal cover.
