Abstract
A steering axle with hydrostatic two-circuit steering system for agricultural, forestry and construction vehicles. The steering axle includes a first double-acting pressure medium cylinder (1) which in the area of its center is connected with an axle bridge housing (2) and at its two ends with joint housings (4, 5) via tie bars (3) and an additional second double-acting pressure medium cylinder (6) which is mounted on one side of the axle. The second cylinder acts simultaneously together with the first pressure medium cylinder (1). In this manner a two-circuit steering system is obtained. At the same time said second double-acting pressure medium cylinder (6) is connected at one end via a ball joint (7) with a joint housing (5) and at the other end is fastened on the axle bridge housing (2).
