摘要： A flow control valve includes a cylinder (55) in which an inflow port (52), an outflow port (53) and a return port (54) are formed. A spiral choke (60) is formed between the inflow and outflow ports. A working oil introduced from the inflow port into the cylinder flows out from the outflow port through the spiral choke. An actuating valve (56) in the cylinder so as to open and close the return port in accordance with a difference in pressure between the inflow and outflow port sides of the spiral choke. When the pressure difference exceeds a predetermined value, the actuating valve opens the return port so that a part of the working oil introduced into the cylinder is returned to the inflow side of the flow control valve.

摘要： A vehicle steering control system for steering both front and rear wheels is so arranged that a transfer function between a driver's steering input and a front wheel steering angle, and a transfer function between the steering input and a rear wheel steering angle are differentiated from each other so as to obtain an optimum cornering characteristic of the vehicle. The system has a steering input sensor (6), a vehicle speed sensor (10), means (8) for determining the transfer function for the front wheels from a steering frequency and a vehicle speed, means (9) for determining the transfer function of the rear wheels, a front wheel actuator (13) for steering the front wheels, and a rear wheel actuator (14) for steering the rear wheels. The means for determining the transfer function of the rear wheels may be an electronic circuit (9), or a hydraulic fluid flow restrictor (54) such as an orifice, or a mechanical gearing (4).

摘要： PURPOSE:To secure a steering ratio corresponding to a running state, by controlling both operations of a first connecting member connecting front side link members themselves of symmetrical rear wheels and a second connecting member connecting rear side link members themselves, while making the steering ratio of front wheels to rear wheels variable. CONSTITUTION:In time of left turning operation of a wheel 3, symmetrical front wheels 2L and 2R are steered to the left. Simultaneously, pressure in a right chamber 7d of a front cylinder 7 goes up and transmitted to a right chamber 14d of a front side rear cylinder 14. Therefore, a piston 14b moves to the left and thereby rear wheels 9L and 9R are steered to the left. Thus, a steering ratio of front wheels to rear wheels comes to be constant. When a steering angle of these front wheels becomes more than the specified value, a flow dividing valve 22 is selected by pressure in the right chamber 7d whereby the pressure is led into a right chamber 15d of a rear wheel rear cylinder 15, and these rear wheels are therefore steered to the right. Afterward, the flow dividing valve 22 is restored, and these rear wheels are steered to the left again. Since the valve 22 repeats these operations, these rear wheels are steered at a steering ratio different from the preceding one. Making spring load of both valves 21 and 22 is made variable so that such a steering ratio as being commensurate to a driving state is securable.
摘要翻译：目的：为了确保与行驶状态相对应的转向比，通过控制连接对称后轮的前侧连杆构件本身的第一连接构件和连接后侧连杆构件本身的第二连接构件的操作，同时使转向比前轮到后轮可变。构成：在车轮3的左转操作时，对称的前轮2L和2R向左转向。同时，前缸7的右室7d中的压力上升并传递到前侧后缸14的右室14d。因此，活塞14b向左移动，从而后轮9L和9R转向剩下。因此，前轮与后轮的转向比变得恒定。当这些前轮的转向角度大于指定值时，在右室7d中通过压力选择分流阀22，由此压力被引导到后轮后缸15的右室15d中，并且这些后因此，轮子转向右边。此后，分流阀22被恢复，并且这些后轮再次向左转向。由于阀22重复这些操作，所以这些后轮以与前一个不同的转向比转向。使两个阀21和22的弹簧负载可变，使得与驱动状态相当的转向比可以保证。

摘要： A power steering system of a vehicle and a control method are provided. The integrated power steering system reduces the number of components, manufacturing costs, and power loss of a vehicle using components together, such as a hydraulic pump, a controller, and a control valve, used in an emergency steering system and a rear wheel steering system. The system includes a main hydraulic motor that receives engine power and generates a hydraulic pressure and an auxiliary hydraulic motor that generates a hydraulic pressure. A front wheel steering cylinder receives hydraulic pressure and generates power for steering front wheels and auxiliary steering of a driver and a rear wheel steering cylinder receives hydraulic pressure and generates power for steering rear wheels. An integrated control valve is connected to the hydraulic motors and the steering cylinders through hydraulic pressure pipelines, and adjusts the hydraulic pressure generated by a main hydraulic motor to supply the pressure to the front wheel steering cylinder and adjusts the hydraulic pressure generated by the auxiliary hydraulic motor to supply the pressure to the front wheel steering cylinder or the rear wheel steering cylinder. A controller operates the auxiliary hydraulic motor and the integrated control valve to supply the hydraulic pressure generated by the main hydraulic motor to the front wheel steering cylinder and the hydraulic pressure generated by the auxiliary hydraulic motor to the front wheel steering cylinder or the rear wheel steering cylinder when the steering wheel is manipulated.
