Patent ID: 7931282

Claim:
In a motor vehicle suspension system comprising a pair of front wheel corners and a pair of rear wheel corners, wherein at least one of the pairs of front and rear wheel corners comprises a suspension attachment member and a semi-elliptical spring having a distal end thereof attached to the suspension attachment member; wherein an improvement thereto comprises an automatically variable ride height adjustment apparatus, comprising: at least one electric motor; an actuation control for said at least one electric motor; a plurality of drive links connected to said at least one electric motor; and a plurality of drive members, one drive member being respectively disposed at each wheel corner of the at least one pair of front and rear wheel corners that comprise a suspension attachment member and a semi-elliptical spring having a distal end thereof attached to the suspension attachment member, each drive member comprising: a rotatively driven component connected drivingly to a respective said drive link; and at least one stationary component threadingly interfaced with said driven component; wherein said driven component and said at least one stationary component are connected with the distal end of the semi-elliptical spring and the suspension attachment member such that when said at least one electric motor is actuated responsive to said actuation control, said plurality of drive links cause rotation of each said driven component relative to its respective said at least one stationary component, thereby resulting in a distance between the distal end of the respective semi-elliptical spring and the respective suspension attachment member to change responsive to the rotation.
