Abstract
The invention relates to a hydraulic steering device for the chassis of a vehicle, in particular of a crane or transport vehicle, with chassis axles steerable between longitudinal and transverse drive positions and in each case fixed to a shaft on the vehicle that is pivoted about a vertical swiveling axle, on which shaft a steering cylinder acts by way of at least one laterally projecting control arm for swiveling of the shaft. The steering cylinder acting on the projecting control arm and a further steering cylinder acting on a vehicle frame beam are articulated to a lever arm, coaxially pivoted on the shaft, in such a way that the torsional movement of the shaft resulting from the retracting and extending movement of the two steering cylinders adds up to at least .+-.90.degree..
