  • Publication number: 20150001915
    Abstract: A braking device for a vehicle is provided which includes a hydraulic booster to make wheels of the vehicle produce frictional braking force. The hydraulic booster includes a fluid chamber and a throttle. When a brake pedal is depressed suddenly, the throttle works to obstruct or restrict an outflow of brake fluid from the fluid chamber, thereby increasing the pressure in the fluid chamber. This causes the pressure in a master chamber of the hydraulic booster to rise, thereby producing the frictional braking force almost no later than start of the depression of the brake pedal.

  • Publication number: 20140265542
    Abstract: A braking system for a vehicle is operative to apply a friction brake force to at least one wheel of the vehicle. The braking system includes a master cylinder is in fluid communication with a reservoir of brake fluid and in fluid communication with the hydraulic brake device. According to one aspect, the braking system includes an electric brake force generator which moves the brake fluid within the master cylinder to deliver brake fluid to the friction brake device in response to a first predetermined displacement of a brake pedal. The electric brake force generator includes a housing defining a boost chamber filled with brake fluid and in fluid communication with the reservoir of brake fluid and further includes a drive arrangement for creating pressure in the boost chamber.

  • Publication number: 20110227405
    Abstract: In a reservoir tank (5) of the present invention, a hydraulic fluid movement deterring wall (26) is disposed integrally with an upper half body (9) and extending toward a radial direction center of a cylindrical upper half body neck section (24) on a curved portion at a boundary between an inner peripheral surface (24a) of the cylindrical upper half body neck section (24) and an inner surface (25a1) of a ceiling portion (25a) of an upper half body trunk section (25) or on the inner peripheral surface (24a) of the upper half body neck section (24). The movement of the hydraulic fluid frontward (toward a hydraulic fluid inlet (10)) in a hydraulic fluid storage chamber 13 at a time when the reservoir tank (5) is tilted frontward is controlled by this hydraulic fluid movement deterring wall (26).

  • Publication number: 20110066345
    Abstract: Fluctuations in a braking force and a deceleration during regenerative cooperative control are suppressed. A brake system includes a master pressure generating device 200, a wheel pressure generating device 300, and a regenerative braking device 18 that operate brake calipers 21a to 21d of respective brakes, and a brake control device 100 that control the actuators 200, 300, and 18. The brake control device 100 includes a braking force calculating unit 111 that determines a frictional braking force outputted at the brake calipers 21a to 21d and a regenerative braking force outputted by the regenerative braking device 18, and a communication control unit 112 that outputs braking force signals corresponding to the respective braking forces to the respective actuators 200, 300, and 18. The brake control device 100 controls the braking forces based on a pedal reaction force and a displacement amount of a piston that pressurizes a master cylinder.

  • Patent number: 7584042
    Abstract: There is provided a new and novel vehicle running control device for correcting a yaw angle of a vehicle toward the yaw direction intended by a driver, together with vehicle stability control, through generating yaw moments. In order to accomplish the yaw angle correction, the inventive device operates a yaw moment generating apparatus e.g. a steering apparatus, so as to generate a direction correcting yaw moment based upon an integration value of the deviations between an actual yaw rate and its target value. The direction correcting yaw moment may be generated for correcting the yaw angle deviation remaining after the stability control is ended.

  • Publication number: 20090033145
    Abstract: A braking system for a high speed, high load rotor operating in a vacuum and suspended by a magnetic field such as in a flywheel energy storage device includes a pair of calipers disposed on opposed sides of the rotor for actuating a pair of annular friction discs into engagement with opposed sides of the rotor. Each caliper includes a mounting ring on its outer edge and an inner shallow annular groove in which it disposed one of the friction discs. A circulating fluid under pressure is directed into each annular groove for urging each friction disc into engagement with one of the opposed surfaces of the rotor for safely bringing the rotor to a stop such as in an emergency. The circulating fluid removes the heat generated by the braking action, while the controlled pressure applied by the discs also controls the position of the rotor when static such as during initialization.

  • Patent number: 4015720
    Abstract: Apparatus for automatically coupling pneumatic brake lines on railway wagons and other articulated vehicles. The apparatus comprises an axially and resiliently compressible tubular projection which is fitted to the end of the vehicle to extend outwardly beyond the coupling plane of the vehicle. The head at the free end of the projection is formed to align and connect airtightly with a similarly formed head at the free end of a like formation on an adjacent vehicle when the draw-gear of the vehicles is coupled. This action compresses each projection thereby opening a valve between the bore of the projection and the brake line of its associated vehicle. The valve is releasably locked in the open position so that if the vehicles are uncoupled deliberately or accidentally, air in the brake line will be dissipated thus applying the brakes of the vehicle.
