Abstract
A suspension module includes a spindle pivotably connected to an axle with a pivot element defining a vertical axis. The spindle has an attachment member and an attachment cap, with outer ends are rigidly interconnected by a pair of lift cylinders. The spindle includes a plate extending between the lift cylinders intermediate the attachment member and cap with the pivot element received between the attachment member and plate. Each lift cylinder has a ram movable within a housing of the lift cylinder. A wheelbox mounts to the wheel and couples with the spindle. First and second strut rods connect the wheelbox with the ram of one of the lift cylinders, and third and fourth strut rods connect the wheelbox with the ram of a second lift cylinder. The strut rods allow the spindle to move relative to the wheelbox while also transferring pivot torque between the wheelbox and the spindle.
