Abstract: A control device for an oscillating axle suspension, in particular a front axle suspension, includes at least of one hydraulic accumulator device (10), a suspension device (12) and a proportional valve (14) having a valve piston (26). The proportional valve (14) is connected to the accumulator and suspension devices (10, 12) via fluid ports (16, 18, 20, 22). The valve piston (26) is actuatable by an electric motor (28), is longitudinally guided in a valve housing (24) of the proportional valve (14) and controls the fluid ports (16, 18, 20, 22) such that, in at least one functional position of the valve piston (26), the axle oscillation is provided while the suspension is blocked and, in at least one further second functional position of the valve piston (26), the suspension is provided while the axle oscillation is blocked.
