Abstract: A hydraulic brake device is provided with a master cylinder for supplying pressurized fluid to plural brakes which respectively restrict the rotations of road wheels, a solenoid block mounted on the master cylinder and containing plural solenoid valves, and an ECU provided with a control board for controlling the solenoid valves to distribute pressurized fluid to the plural brakes and also provided with a case for containing the control board therein. The solenoid block and the ECU are constructed to be an integrated structure, and the integrated structure composed of the solenoid block and the ECU is removably mounted on the master cylinder. Further, the ECU is secured to the solenoid block by means of screw bolts which are arranged within an area insider the external form of the control board. Thus, it becomes unnecessary to provide bolt seats for the screw bolt outside the case, so that the case and hence, the ECU can be miniaturized. Further, for replacement of the control board, the integrated structure is removed from the master cylinder and is replaced with a new one as a part, instead of disjoining the control board per se from the ECU to replace the control board with a new control board as a part. Thus, it can be avoided that the reliability of the ECU is deteriorated due to disjoining the control board and rejoining the new control board.
Abstract translation: 液压制动装置设有主缸,用于将加压流体供给到分别限制车轮转动的多个制动器,安装在主缸上的电磁铁块并且容纳多个电磁阀,以及设置有用于控制的控制板的ECU 电磁阀将加压流体分配到多个制动器,并且还设置有用于在其中容纳控制板的壳体。 螺线管块和ECU构成为一体结构,由螺线管块和ECU组成的一体结构可拆卸地安装在主缸上。 此外,ECU通过设置在控制板的外部形式的区域内的螺栓固定在螺线管块上。 因此,不需要在壳体外部设置用于螺栓的螺栓座,因此能够使ECU小型化。 此外,为了更换控制板,将整体结构从主缸移除并作为一部分被替换为新的,而不是将控制板本身与ECU分离,以用新的控制板来替换控制板 作为一部分。 因此,可以避免由于分离控制板并重新接合新控制板而导致ECU的可靠性恶化。
