Abstract
A hydraulic unit of an electronic control brake system capable of achieving compactness of a modulator block by optimizing connection between components and valves, which are mounted in the modulator block, is disclosed. The hydraulic unit of an electronic control brake system includes a modulator block mounted with components to control braking hydraulic pressure applied to wheels of an automobile, including a plurality of inflow and outflow valves, a traction control valve, a shuttle valve, an accumulator, a pump and a motor. The modulator block is formed with oil lines thereinside to connect the components. The modulator block has a hexahedral shape. A wheel cylinder connecting part is disposed at a first surface of the modulator block, and a master cylinder connecting part is disposed at a second surface of the modulator block. Accordingly, a width of the surface, at which the wheel cylinder connecting part is disposed, can be decreased. Since the traction control valve is positioned above the shuttle valve at a rear surface of the modulator block, and the motor is positioned at a center portion of the modulator block, an overall size of the modulator block becomes compact.
