US Patent 10161471 Suspension systems and methods of operating same

Suspension systems include a gas spring and gas damper assembly that is adapted for operation in first and second conditions. In the first condition, the assembly provides spring and damping functionality across a first range of travel. In the second condition, the assembly provides actuator functionality with a second range of travel that is substantially less than the first range of travel. A pressurized gas system is in fluid communication with the assembly. A control system is in communication with the assembly and the pressurized gas system. The control system is operative to actuate one or more control devices to transfer pressurized gas and thereby transition the assembly from between the first and second conditions. Methods of operating such as suspension system are also included.
