Abstract

A decoupled mono tube damper assembly includes an outer tube attached to a vehicle's unsprung mass. The outer tube has a base and a sleeve end. An outer tube sleeve engaging end of an inner tube is slidingly engaged with the sleeve end. The inner tube has an end distal to the sleeve engaging end, and is attached to the vehicle's sprung mass at the distal end. A damper rod has one opposed end extending axially into a base aperture, and an opposed end connecting to the inner tube. The rod moves axially relative to the outer tube. A low amplitude energy-managing member is operatively disposed within the outer tube, and has a throughbore receiving the rod. A travel-limiting member attaches to the rod and is engageable with the energy-managing member to constrain axial movement of the rod through the outer tube base to a predetermined limit.
