Abstract | A multistage jounce bumper, including a jounce bumper cushion integrated with a hydraulic jounce bumper, wherein provided are the damping characteristic of the hydraulic jounce bumper and the damping/spring characteristics of a jounce bumper cushion. The hydraulic jounce bumper hydraulic response is tunable via adjustment of hydraulic flow with respect to a communicating hydraulic fluid reservoir. When maximum jounce is approached, jounce force and energy are exchanged, at a first stage, with the jounce bumper cushion, then at a predetermined compression, jounce force and energy are exchanged, at a second stage, with the hydraulic jounce bumper. Thereafter, a mechanical abutment is provided as a third stage of jounce management. |
