  • 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: 20150000266
    Abstract: A braking device for a vehicle is provided which is equipped with a hydraulic booster. The hydraulic booster includes a master cylinder, a braking simulator, and an input piston. The input piston is disposed in the master cylinder in connection with a brake actuating member such as a brake pedal and is moved in response to a braking effort applied to the brake actuating member to drive a spool valve which switches among a pressure-reducing mode, a pressure-increasing mode, and a pressure-holding mode. The braking simulator works to urge the input piston rearward and is disposed inside a cylindrical cavity of the master cylinder of the hydraulic booster. This layout improves the mountability of the braking device in vehicles.

  • Publication number: 20150001917
    Abstract: A braking device for a vehicle is provided which includes a servo unit working to develop a hydraulic pressure which generates a braking force. The servo unit is actuated following movement of a movable member to develop the hydraulic pressure. The movable member moves in response to a braking effort. The braking device has an elastic member working to create resistance to the movement of the movable member relative, so that the resistance is different between when the movable member moves in a frontward direction and when the movable member moves in a backward direction. This produces a hysteresis in relation of the brake effort to the amount of movement of the movable member.

  • Publication number: 20150001916
    Abstract: A braking device for a vehicle is provided which includes a power fail-safe mechanism which works to create frictional braking force at a wheel of the vehicle in the event of loss of electric power. The braking device is equipped with an electromagnetic valve which is of a normally closed type. In the event of loss of electric power in the braking system, the electromagnetic valve is closed to block fluid communication between a hydraulic booster and a brake fluid reservoir, so that a stroke chamber in the hydraulic booster is hermetically closed. This enables the pressure in a master cylinder to rise in response to depression of a brake pedal to develop the frictional braking force.

  • Publication number: 20140116244
    Abstract: A pressure control reservoir for a vehicle brake system is disposed in a hydraulic line extending from a master cylinder to a wheel cylinder through a pump. The pressure control reservoir includes a check valve which consists of a valve seat and a valve. The check valve is closed when an excessive pressure of brake fluid produced by the master cylinder. The valve is stationary. The valve seat is moved in response to an elevated level of the pressure of brake fluid into engagement with the valve, so that the check valve is closed. With these arrangements, the check valve is closed before a piston starts to move to change the volume of a reservoir chamber, thus permitting the volume of the brake fluid required to close the check valve to be decreased, which minimizes the uncomfortable feeling given to a driver of the vehicle when actuating the brakes.
