Abstract
Systems and apparatuses include a chassis mount configured to couple to a vehicle chassis, an axle assembly including wheels, a four-bar linkage coupling the axle assembly to the chassis mount, and a hydraulic cylinder coupled between the chassis mount and the axle assembly. The hydraulic cylinder actuates the axle assembly between a raised position and a lowered position and acts as a spring damper suspension component.
