  • Motion Control System
    Publication number: 20230278386
    Abstract: A motion control system includes a top mount, a bottom mount, a rigid housing, an air spring, and a linear actuator. The air spring transfers force of a first load path between the top mount and the bottom mount. The air spring includes a pressurized cavity containing pressurized gas that transfers the force of the first load path. The linear actuator transfers force of a second load path between the top mount and the bottom mount in parallel to the first load path. The rigid housing defines at least part of the pressurized cavity and transfers the force of the second load path.
