    摘要: An den Stellgliedern (6) zum Lenken der Hinterräder eines Kraftfahrzeuges ist jeweils eine elektromagnetisch betätigbare Sperre (8) vorgesehen. Diese ist so ausgebildet, daß sie im nicht bestromten Zustand die maximal mögliche Verschiebebewegung einer Stellstange (12) des Stellgliedes (6) auf das Maß begrenzt, welches zum Lenken bei höheren Fahrgeschwindigkeiten erforderlich ist. Bei geringen Fahrgeschwindigkeiten ist die Sperre (8) gelöst, so daß dann zum Parkieren größere Radeinschläge möglich sind.

    摘要: A control device allows the hydraulically assisted steering force to be varied in function of the vehicle speed. At low speed, the hydraulic power assistance is strongly boosted, and is increasingly reduced with increasing speed. The control device comprises an electronic switchgear (10) which controls the flow through an adjustable choke (7), for example a magnetic value, in function of a speedometer signal. The adjustable choke (7) is lodged in a supply line (3) of a power-assisted steering (4, 5, 6). A manometric switch (14) arranged in the supply line (3) downstream of the adjustable choke (7) can supply a control signal to the switchgear (10). If the driver swerves suddenly at high speed in an emergency, the pressure drop causes the manometric switch (14) to actuate the switchgear (10), which in turn opens the adjustable choke (7). This boosts the power-assist function and ensures that the sudden steering movement can be executed safely.

    摘要: A power steering apparatus wherein, when action of a hydraulic actuator of a source for steering assisting power is converted into steering motion, the steering momentum obtained in response to a specified magnitude of operation of the hydraulic actuator is larger at the central side of a rotation range of a steering wheel than at the end side thereof. The steering assisting power becomes larger as the steering angle becomes larger. As a result, when the steering wheel is largely operated, a burden of labor for steering is largely reduced without expecting an increase in capacity of the hydraulic actuator.

    摘要: A power steering mechanism for vehicles comprising:
    a control valve (1) having first and second valve members (2, 3) which are relatively movable to direct fluid under pressure to one side or the other of a double-acting power steering motor (14);
    resisting means for resisting relative movement between said first and second valve members (2, 3) with a force which varies as a function of vehicle speed to decrease said force with decreasing vehicle speed and increase said force with increasing vehicle speed, said resisting means comprising:
    a force-transmitting member (22) connected with said first valve member (2) and movable toward and away from said second valve member (3),
    means for increasing resistance to relative movement between said first and second valve members as said force­transmitting member (22) moves toward said second valve member (3),
    and means for urging said force-transmitting member (22) towards said second valve member (3) with a force which decreases with decreasing vehicle speed and increases with increasing vehicle speed and including a first fluid pressure chamber (30) between said force transmitting member (22) and said second valve member, wherein
    a second fluid pressure chamber (31) is provided on the opposite side of said force-transmitting member (22) to said first fluid pressure chamber (30), and
    speed-responsive valve means (39) is provided for controlling the fluid pressures in said first and second fluid pressure chambers (30, 31) as a function of vehicle speed.

    摘要: The hydraulic power steering apparatus of the present invention has plungers being installed movably at part of a casing of a hydraulic control valve and a reaction chamber being formed at one side of said plungers, and varies hy­draulic pressure to be supplied to a hydraulic pressure reacting portion for generating restriction force cor­responding to supplied hydraulic pressure according to vehicle speed and quantity of relative movement between a valve body and a casing of hydraulic control valve, thereby the supplied hydraulic pressure being increased as the vehi­cle speed becomes higher and steering angle becomes larger.
