摘要： A four-wheel steering system of a vehicle includes a power steering device for steering the front wheels, an oil pressure pump for generating an oil pressure in accordance with a travel speed of the vehicle, and a hydraulic actuator for steering the rear wheels. A first control valve is provided between the pump and the actuator so as to operate upon reception of the oil pressure from the power steering device. This valve introduces the oil pressure from the pump to the actuator in accordance with the oil pressure from the power steering device so that the actuator steers the rear wheels in the same direction as the front wheels. A second control valve is provided between the power steering device and the actuator so as to operate in accordance with the oil pressure from the power steering device. When the oil pressure from the power steering device exceeds a predetermined value, the second control valve operates to introduce the oil pressure from the power steering device to the actuator so that the actuator steers the rear wheels in the opposite direction to the front wheels.

摘要： A rear wheel steering system of the trailing arm type suspension for rear wheels having a trailing arm for supporting at the rear portion thereof a rear wheel and extending essentially in the longitudinal direction of a vehicle body by pivotally securing the front end thereof to the body side. Lateral arms are rotatably coupled at the outer ends thereof to the rear portion of the trailing arm and extending essentially in the lateral direction of the vehicle by pivotally securing the inner ends thereof to the vehicle body. The trailing arm allows the front portion thereof to displace essentially in the lateral direction of the vehicle. The rear wheel suspension arrangement allows the trailing arm to displace substantially in the lateral direction of the front end thereof and which comprises an actuator for steering a rear wheel by operating the trailing arm to displace the front portion of the trailing arm essentially in the lateral direction of the vehicle.

摘要： A rear wheel suspension arrangement of trailing arm type for motor vehicles includes a trailing arm for supporting a rear wheel, and a pair of upper and lower lateral arms. The trailing arm is split into a vehicle body side arm and a wheel side arm, which are coupled to have a degree of displacing freedoms within a horizontal plane of the vehicle body. The vehicle body side arm is formed shorter than the lateral arms, whose pivotally securing portion to the vehicle body is disposed at the front side from the coupling portion to the wheel side arm, and disposed in the inside in the lateral direction from the wheel side arm. The lower lateral arm is pivotally secured at least to the wheel side arm via a ball joint.

摘要： A flow control valve includes a cylinder in which an inflow port, an outflow port and a return port are formed. A spiral choke 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 is arranged 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.
