Abstract
A vehicle includes a vehicle structure, a wheel assembly, a control arm that is connected to the wheel assembly and the vehicle structure by pivot joints, and an active suspension actuator that is connected to the control arm and to the vehicle structure. The vehicle also includes an air reservoir that includes a first port and an air spring that supports the vehicle structure with respect to the control arm and is able to compress and expand. The air spring includes an internal working volume, the air spring includes a second port that is in fluid communication with the internal working volume, and the second port is connected to the first port to allow exchange of air between the internal working volume of the air spring and the air reservoir in response to compression and expansion of the air spring.
