摘要： A brake control apparatus includes a master cylinder, wheel cylinders provided for each vehicle wheel, first and second hydraulic actuators provided separately from the master cylinder and adjusting a hydraulic pressure of the wheel cylinder. The first and second hydraulic actuators respectively have first and second hydraulic pressure sources and each have a wheel cylinder system. The first hydraulic actuator adjusts the hydraulic pressure of the wheel cylinder belonging to the one wheel cylinder system between the wheel cylinders by the first hydraulic pressure source. The second hydraulic actuator adjusts the hydraulic pressure of the wheel cylinder belonging to the other wheel cylinder system than the above wheel cylinder system by the second hydraulic pressure source.

摘要： A gear pump includes a drive shaft, a rotatable pump element mounted on the drive shaft, a side wall member disposed on one side of the pump element, and formed with a shaft hole through which the drive shaft extends, and a side plate disposed on the other side of the pump element. The gear pump further includes a connecting section connecting the drive shaft with the pump element in a manner to prevent relative rotation and to allow relative axial movement between the drive shaft and the pump element. The connecting section includes a drive recess formed in the pump element, and a drive projection projecting radially outwards from the drive shaft, and engaging in the drive recess to prevent the relative rotation. The drive projection is arranged to limit the axial movement of the drive shaft relative to the pump element with one of the side wall member and the side plate.
摘要翻译：齿轮泵包括驱动轴，安装在驱动轴上的可旋转的泵元件，设置在泵元件一侧的侧壁件，并且形成有驱动轴延伸穿过的轴孔和设置在其上的侧板泵元件的另一侧。齿轮泵还包括连接部分，该连接部分以防止相对旋转并允许驱动轴和泵元件之间的相对轴向运动的方式连接驱动轴与泵元件。连接部分包括形成在泵元件中的驱动凹部和从驱动轴径向向外突出的驱动突起，并且与驱动凹部接合以防止相对旋转。驱动突起被布置成通过侧壁构件和侧板中的一个来限制驱动轴相对于泵元件的轴向运动。
