PURPOSE: A contactless hydraulic brake system is provided to control the rotational speed of the wheel by controlling the rotation of the crank shaft connecting the piston and the wheel through opening/closing of hydraulic path. CONSTITUTION: A contactless hydraulic brake system comprises a crank shaft(10), a cylinder(50), oil, a piston(20), a damper(70) and a knob(40). The crank shaft rotates with a wheel(1). The cylinder in which a flow path is formed is connected to a tank(60). The oil is as incompressible fluid is filled in a flow path of the cylinder. The piston is inserted into the flow path of the cylinder while being connected to the crank shaft and pushes out the oil from the cylinder by converting the rotational motion of the crank shaft to a linear motion. The damper controls the opening and closing of the flow path of the oil moved by the piston and lowers the flow rate of oil to restrain the linear motion of the piston. The knob operates the damper by means of a damper actuator. |
