Abstract: A suspension system for a vehicle includes a damper and a jack assembly. The damper includes a first tube defining a first cavity and having a longitudinal axis, a second tube disposed within the first cavity and defining a second cavity, wherein the second tube is spaced apart from the first tube to define a reservoir chamber, and a piston translatable within the second cavity along the axis, wherein the piston abuts the second tube to define a rebound chamber and a compression chamber. The system includes a jack assembly attached to the damper and configured for raising and lowering the body with respect to the wheel. The assembly includes a jack piston abutting the first tube, and a jack cylinder also abutting the first tube and translatable with respect to the jack piston to thereby raise and lower the body. A vehicle including the suspension system is also disclosed.

Abstract: A suspension system for a vehicle includes a damper having a central longitudinal axis, and a jack assembly attached to the damper. The jack assembly includes a seat abutting and rotatable about the damper, a resilient member coiled about the damper and coupled to the seat so that the resilient member is not rotatable with respect to the seat, a ball screw abutting and fixedly attached to the damper, wherein the ball screw is not rotatable about the damper, a ball nut abutting and rotatable about the ball screw and the damper, a first clutch coiled about the ball nut and coupled to the seat, and a second clutch coiled about the damper and coupled to the ball nut. The seat is translatable along the damper to thereby raise and lower the body of the vehicle. A vehicle including the suspension system is also disclosed.
