The invention relates to a system (1) for steering steerable wheels (2) of a trailer (3), comprising a hydraulic control circuit (11), a hydraulic element (4) for absorbing a movement of a vehicle pulling the trailer (3), which hydraulic absorbing element (4) is connected for signal generation to the hydraulic control circuit (11), a hydraulic operating element (12) connected to the hydraulic control circuit (11) and acting on a steerable wheel (2), and means (20) connected to the hydraulic control circuit (11) for actively steering the steerable wheels (2), which active control means (20) comprise a pump (21). The hydraulic control circuit (11) may comprise a pressure-relief valve (28) arranged between the absorbing element (4) and the operating element (12) and a non-return valve (30) arranged between the pump (21) of the active control means (20) and the operating element (12), while the pressure-relief valve (28) and the non-return valve (30) may be integrated in a single valve unit (27). The system (1) may be provided with two absorbing elements (4) and two operating elements (12), wherein the hydraulic control circuit (11) comprises a single pressure sensor (39) which is connected for signal generation to the pump (21) of the active control means (20).
