Title: Noise reduction device of anti-lock brake system
Inventor: JUNG BYEONG HU
IPC: B60T8/00
Filed: 2000-03-27
Abstract: PURPOSE: A noise damper of an ABS(Anti-lock Brake System) is provided to reduce the working noise of an ABS and to improve reliability by damping pressure pulsation from a driving pump efficiently. CONSTITUTION: A noise damper(80) of an ABS includes: a cylindrical housing(81) having an end combined to an in-port(71) and the other end opened; a coupler(82) connected to close the opening of the housing and communicated with the end of a hydraulic line coupled with a master cylinder; and a damping member piled up inside the housing to damp the pressure pulsation of oil. When a driver steps on a brake pedal, a considerably high pressure of braking force is generated from the master cylinder. The braking force is delivered to a hydraulic brake through the noise dampers, the in-ports and NO type solenoid valves(30). The velocity of a running vehicle is reduced. The oil pressure in the hydraulic brake is returned to the master cylinder through the NO type solenoid valves, the in-ports and the noise dampers when the driver puts the foot off the brake pedal. Thereby, the braking force is reduced or removed completely. An ECU(Electronic Control Unit) closes the NO type solenoid valves and opens NC type solenoid valves(31) to reduce the brake force. The oil is kept in a low-pressure accumulator temporarily through out-ports(72) and the NC type solenoid valves from the hydraulic brake. Therefore, the braking force of the hydraulic brake is reduced and the vehicle is prevented from skidding on road surface.
