Disclosed is a braking device in which all multiple ports (for example, input ports (15c, 15d) and output ports (15a, 15b)) provided on a front surface portion (30) of a base (10) of a master cylinder (1), connector connection ports (23a, 24a) of connectors (23, 24) that electrically conducts an electrical part accommodated in a housing (20), and a pipe connection port (3c) to which a hose is connected of a reservoir (3) are arranged toward front of a vehicle when a starting device (A1) is assembled in the vehicle.

An integrated brake device for a vehicle according to an embodiment of the present invention includes a master cylinder that generates a hydraulic pressure based on the operation of a pedal, a pedal simulator that provides a pedal stepping force to the pedal based on the hydraulic pressure, a motor that is driven based on displacement of the pedal, a pump that applies a braking pressure to wheels of the vehicle based on the driving of the motor, and a gear unit that converts rotational power of the motor into a linear motion of a piston included in the pump, wherein a rotating shaft of the motor is parallel to a direction of the linear motion of the piston.

One embodiment provides a vehicle brake hydraulic pressure control apparatus. The apparatus includes an inlet valve; an outlet valve; a pump; a motor and a control unit. The control unit executes an antilock brake control and a control to return a brake fluid accumulated in a reservoir due to a pressure decreasing control in the antilock brake control to a hydraulic pressure source by driving the motor. The control unit includes: a target delivery amount calculator configured to calculate a target delivery amount which corresponds to an amount of brake fluid discharged from the reservoir per a predetermined time; a temperature information fetcher configured to acquire a temperature of the brake fluid; and a drive signal determinator configured to determine a drive signal of the motor based on the target delivery amount and the temperature of the brake fluid.

Hydraulic valves for dampening pressure spikes and associated methods are disclosed herein. In one embodiment, a hydraulic valve for dampening pressure spikes includes: a spool configured to move axially inside the hydraulic valve; and a sleeve configured to at least partially house the spool. A location of the spool with respect to the sleeve may determine a flow of a working fluid through the hydraulic valve. A viscous damper is at least partially housed inside an opening in the spool, and a viscous friction between the viscous damper and the opening in the spool slows a motion of the spool.

Electrohydraulic assembly for a brake system, having a hydraulic unit comprising a housing body which houses electrically actuable valves and a hydraulic pump having an electric drive apparatus for the pump, having an electronic unit arranged on the housing body for controlling the valves and/or the drive apparatus, and having a pressure medium reservoir which comprises a first space for pressure medium, a vented second space and a media-separating element that separates the first space from the second space, wherein the pressure medium reservoir is connected to a suction side of the pump, and wherein the pressure medium reservoir is embodied as a pressure medium supply reservoir to keep pressure medium ready for the pump for increasing brake pressure or while the pump increases brake pressure, and brake system having such an assembly.

In one embodiment, a solenoid valve for a vehicle braking system includes a magnet assembly having a winding support, a coil winding, a housing, and a cover disc. The solenoid value further includes a valve cartridge having a capsule, a valve insert, a valve seat, and an armature. The valve insert can be connected to the capsule, the armature can be guided within the capsule in an axially movable manner and has a closing element. The closing element and the valve seat can form a valve that can control a fluid flow through the valve cartridge. The coil winding can be wound on the winding support to form an electrical coil, which can be controlled using control signals applied to electrical connectors. The electric coil generates a magnetic force that can move the armature against a force of a return spring.
