Abstract
A suspension for a ground vehicle which connects a rigid axle to the vehicle chassis and stabilizes the rigid axle in fore, aft, and rotational directions. The suspension comprises four links and a swivel. The four links extend within a predetermined number of degrees of parallel to a longitudinal axis of the vehicle, and connect the rigid axle to the vehicle chassis. Two of the links are normally attached above, and two of the links are normally attached below the rigid axle centerline. Therewith, the swivel comprises an arm having two opposite ends and a centrally positioned pivot shaft. Each end of the arm being interposed between an end each of two of the four links thus the pivot shaft is held steadfast to the surface residing between the locations where the pair of link ends would otherwise attach. Said surface being either of the vehicle framework or of the rigid axle, whichever location is preferred. Furthermore, the improvement to the above described swivel four-link suspension comprises a method for an adjustable means which makes it relatively easy to vary the inclination of the swivel pivot shaft axis upon the surface to which the pivot shaft is held firm. Therefore, the swivel arm pivot motion angle can be realigned with the swivel attaching link pair's push-pull direction, for optimal swivel functioning, whenever a change is made to the setup angle of the swivel attaching link pair.
