Abstract:
1. A jounce control damping system comprising: an elongated housing containing a damping medium; a moveable outer piston assembly disposed within the housing; a movable inner piston assembly disposed at least partially within the outer piston assembly; said inner piston assembly being configured to engage a primary piston assembly as said primary piston assembly is moved beyond a first compression movement distance through the damping medium causing the inner piston assembly to move in the compressive direction through the damping medium; and said outer piston assembly being configured to move in the compressive direction through the damping medium in response to the inner piston assembly moving in the compressive direction through the damping medium beyond a second compressive movement distance, wherein the primary piston assembly provides a first compression damping force during the first compression movement distance of the primary piston; wherein the inner piston assembly provides a second compression damping force during the second compression movement distance of the inner piston assembly and the outer piston assembly provides a third compression damping force greater than the second compression damping force during the third compression movement distance; wherein the outer piston assembly forms a housing for the inner piston assembly; wherein the outer piston assembly is disposed and moveable within a second housing; wherein the damping medium flows through the primary piston assembly, the inner piston assembly and the outer piston assembly.
