PURPOSE: A braking device for an electric automobile is provided to improve the braking ability of an automobile through controlling pressure control time according to the load change and property of an automobile. CONSTITUTION: A braking device for an electric automobile comprises a master cylinder(110), a first rear brake oil line(120), a rod sensing control valve(130), a second rear brake oil line(140), an oil pressure control valve(150), a front brake oil line(160), an oil control valve(170). The first rear brake oil line is installed in the master cylinder and transfers the oil supplied by the master cylinder. The rod sensing control valve is installed in the first rear brake oil line and controls the pressure of the transferred oil from a rear brake(10). The second rear brake oil line is connected to the rod sensing control valve and transfers the oil transferred by the rod sensing control valve to the rear brake. The oil pressure control valve is installed to control the delay time of the oil transferred to the rear brake according to the load of an automobile. The front brake oil line transfers the oil to the oil pressure control valve. The oil pressure control valve is installed in the front brake oil line and connected to a bypass line(131). The bypass line transfers bypassed oil from the sensing control valve. |
