PURPOSE: A hydraulic steering device of a vehicle is provided to enable a driver to feel pleasant steering comfort by damping noise and vibration due to the vibration of the engine, the pulsation pressure of an oil pump, and shock from the road. CONSTITUTION: A hydraulic steering device of a vehicle comprises a pinion valve assembly(120), a gear box(140), an actuating cylinder(145), and feed tubes(310a,310b). The pinion valve assembly is coupled to a steering shaft. The gear box is coupled to the pinion valve assembly and comprises a rack and a pinion. The actuating cylinder is connected to the gear box so that a rack bar, which is coupled to a piston, makes linear movement by the fluid pressure of working fluid. The feed tube supplies the working fluid from the pinion valve assembly to the actuating cylinder. The feed tube comprises a first tube, a second tube, a damping tube, and a connector. The first tube is coupled to the pinion valve assembly. The second tube is coupled to the actuating cylinder. |
