The pressure connector is connected to at least one wheel brake without a valve being connected in between.

An electro-hydraulic brake system includes a master cylinder (MC) configured to supply fluid into a first MC fluid passageway in response to pressing force on a brake pedal; a pressure supply unit (PSU) assembly having a PSU motor coupled to a ball screw actuator, a PSU housing defining a piston bore having a terminal end opposite the PSU motor, and a PSU piston dividing the piston bore into a first chamber and a second chamber and movable by the ball screw actuator, with each of the first chamber and the second chamber containing a hydraulic fluid; and a backup pump assembly including a pump for supplying the brake fluid to at least one of the wheel brakes. The ball screw actuator includes an actuator nut assembly having a plurality of ball bearings each disposed within the piston bore and submerged in the hydraulic fluid.

A motor pump includes a base body, a pump, and a motor. The motor includes a tubular yoke having a bottom and an opening on a base body side, a bearing, a rotation shaft, a rotor, a commutator, a brush and a brush shaft. The bearing is fitted to an inside of a bearing hole of the base body. The brush holder is fitted to an inside of the yoke and engages with an outer peripheral surface of the bearing. The brush holder and the bearing are disposed so as to be spaced from the base body in an axial direction of the rotation shaft. The motor-side seal member is provided between the yoke and the base body. The base body constitutes a stopper that prevents the brush holder from being extracted from the yoke.

The present invention obtains a brake hydraulic pressure control apparatus for a vehicle capable of suppressing an increase in manufacturing cost thereof when being configured to detect a rotation angle of a rotor.

The brake hydraulic pressure control apparatus according to the present invention is a brake hydraulic pressure control apparatus for a vehicle that includes: abase body that is formed with a channel of a brake fluid; a motor assembly that includes a rotor and a stator and drives a pump device provided in the channel; a control board of a controller that controls the motor assembly; and a housing that accommodates the control board, and that further includes: a permanent magnet that is attached to the motor assembly and rotates with the rotor; and a detection sensor that detects a magnetic field generated by the permanent magnet. The motor assembly is arranged in a space that is surrounded by the base body and the housing, the control board is arranged in a rotation axis direction of the rotor in a manner to oppose the permanent magnet, and the detection sensor is mounted on the control board.

A pump housing arrangement of a hydraulic assembly for a vehicle brake system includes a pump housing. At least one pump is arranged in the pump housing, and is configured to pump brake fluid for the vehicle brake system. A master brake cylinder for the vehicle brake system is also arranged in the pump housing.
