    摘要: The compact hydraulic steering system with a monitor and compensation device, abbreviated CHS-Z, directs a hydraulic actuator within the inner wheel by means of a hydraulic actuator at the handlebars or steer. The compact steering house (2) is situated centrally in the wheel hub (1) around which the wheel spins or on which the wheel is attached. A hydraulic actuator, being a rotary or piston actuator, within the steering house (2) ensures the rotation of the steering axle (3) and the wheel hub (1) to which it is connected. The steering angle of the wheel and the handlebars or steer are kept synchronous by a monitor and compensation device. This steering system distinguishes itself from the traditional steering devices through it extremely compact build inside the wheel hub (1) and the absence of a mechanical connection between the wheel(s) that need to be directed and the handlebars or steer. It offers the constructor a safe and reliable steering system on top of a significant freedom in the design of the wheel suspension.

    摘要: Disclosed is a hydraulic steering system (100) for a vehicle, especially a mobile working machine, comprising at least two steering cylinders (1, 2) within which two cylinder pistons (3, 4) can be displaced, and a first hydraulic pump (14) that can be adjusted regarding the swept volume. The position or the direction of displacement of the cylinder pistons (3, 4) in the steering cylinders (3, 4) defines the steering angle or the steering direction of the steerable vehicle wheels relative to a body (5) of the vehicle. The displaceable cylinder pistons (3, 4) divide the associated steering cylinder (1, 2) into two respective pressure chambers (6 and 7, 8 and 9). The first connection (46) of the adjustable hydraulic pump (14) is joined to one of the pressure chambers (6 or 7, 8 or 9) of the two steering cylinders (1, 2) according to the steering direction while the second connection (15) thereof is joined to the other respective pressure chamber (6 or 7, 8 or 9) of the two steering cylinders (1, 2) in a closed circuit.

    摘要: La roue (1) comporte, de manière connue, un support de roue (4) monté pivotant autour d'un axe (5) sensiblement vertical et proche du plan médian de la roue, grâce à des moyens d'articulation dont l'un au moins est porté par un bras ou triangle oscillant (6, 7) relié au châssis du véhicule par l'intermédiaire d'un axe d'oscillation sensiblement horizontal (9, 12). Le dispositif comporte un actionneur rotatif (14) ayant pour axe de rotation l'axe de pivotement (5) de la roue et constituant le moyen d'articulation du sup­port de roue (4) porté par le bras oscillant (7). Le rotor de l'actionneur (14) est solidaire en rotation du support de roue (4). Le stator est relié au bras oscillant (7) par l'intermédiaire de moyens d'articu­lation (15, 16). Un boîtier (37) permet de commander l'actionneur (14) en fonction de paramètres de condui­te du véhicule. Le dispositif de pivotement est à com­mande indépendante et ne comporte pas d'élément de transmission mécanique.
