A hydraulic rear axle steering for multi-axle vehicles, including a steering cylinder with a piston and two working chambers. The steering cylinder has a mechanical blocking device, which blocks the piston when it reaches a central position within the steering cylinder. The blocking device has a blocking member, which is retained in an engaged position by a locking element in the blocked state. The locking element is movable by a separate, hydraulically actuated actuator between a blocking position and a first unblocking position in which the locking element releases the blocking element. An admission-pressure-controlled load safety valve is provided for each working chamber, and control connections of the valves are connected to a pressure line leading to the respective other working chamber. The actuator is adjusted such that, when a lower, first pressure value is applied, the locking element moves into the unblocking position, and the valves are adjusted such that, when a higher, second pressure value is applied, the valves open towards the tank.
