The hydraulic brake system includes a master cylinder generating braking hydraulic pressure by operation of a brake pedal, a wheel brake provided to each of front right and left wheels and rear right and left wheels of a vehicle to receive the braking hydraulic pressure from the master cylinder to generate braking force, a solenoid valve provided to each of an inlet and an outlet of each of the wheel brakes to control flow of the braking hydraulic pressure, a low pressure accumulator temporarily storing oil, which is ejected from the wheel brakes during operation of the solenoid valves, a pump compressing the oil stored in the low pressure accumulator such that the oil is ejected towards the wheel brakes or the master cylinder as needed, and an orifice disposed near an outlet port of the pump. Further, a damper unit is disposed between the outlet port of the pump and the orifice to reduce pressure pulsation caused by operation of the piston, thereby improving product reliability through noise reduction during brake control.

摘要： A hydraulic brake system includes a master cylinder forming a braking hydraulic pressure and wheel brakes receiving the braking hydraulic pressure and exerting a braking force. A first hydraulic circuit controls an oil pressure transmission by connecting a first port of the master cylinder and two wheel brakes, and a second hydraulic circuit controls the oil pressure transmission by connecting a second port of the master cylinder and remaining wheel brakes. A hydraulic block communicates main passages of the first and second hydraulic circuits with each other by a communication passage having one side opened. Pumps are mounted on the main passages to discharge oil toward the wheel brake or the master cylinder, and an orifice is mounted on each of the other side of the main passages. A damper assembly is coupled to the communication passage provided between an output port side of the pump and the orifice.
