Abstract
A suspension system with an oscillating, rigid axle, particularly for tractors, is described; the axle is supported on a sub-frame with oscillating arms which in turn can be mounted for oscillating on a load-bearing structure of the tractor by suspension means interposed between the axle and the load-bearing structure, the sub-frame comprising at least two pairs of arms arranged so as to form a so-called pantograph-like kinematic linkage.
