Abstract:
A hydraulic brake system for slowing or stopping a rotational driving shaft of a power system with a physical force which is produced by disturbing or stopping the flow of hydraulic oil, comprising:a hydraulic oil reservoir having a hydraulic oil chamber filled with hydraulic oil; a piston device disposed in the hydraulic oil reservoir for being reciprocally and linearly moved; a link device disposed between the piston device and an eccentric cam formed on the rotational driving shaft of the power system, the link device moving in accordance with the rotation of the rotational driving shaft in a manner of tracing a circular arc path upward and downward and forward and backward; a connecting device for connecting the link device and the piston device in a manner that the link device and the piston device are moved in relation to each other; flow rate controlling means disposed in the hydraulic oil passage of the hydraulic oil reservoir for selectively stopping the piston device by controlling the flow rate of hydraulic oil; a protective casing for holding, thus supporting the above-mentioned respective components, the protective casing filled with hydraulic oil; and lubricating means for pumping hydraulic oil of the protective casing to friction sliding sections of the rotational driving shaft, the link device, and the connecting device, respectively.
