Abstract
A suspension actuator includes a first housing part, a second housing part, a ball screw actuator that is connected to the first housing part and to the second housing part, and an air spring membrane that is connected to the first housing part and to the second housing part. The air spring membrane includes a flexible material and a reinforcing structure that is disposed within the flexible material to resist torsion loads that are applied to the second housing part by the ball screw actuator.
