English

Subject field(s)
  • Braking Systems (Motor Vehicles and Bicycles)
CONT

Designed to reduce the amount of pedal pressure needed for braking, electric brake boosters, which use a sensor in the brake pedal to read a driver's actions, are progressively replacing mechanical vacuum brake booster systems. Increasingly used by carmakers to enhance driver comfort and passenger safety, these electric brake boosters use a dedicated electronic system to process the signals from the brake pedal and operate the master cylinder by means of a brushless DC [direct current] motor.

Record 3 2016-11-07

English

Subject field(s)
  • Braking Devices (Mechanical Components)
  • Braking Systems (Motor Vehicles and Bicycles)
DEF

A hydraulic brake actuator mounted inside the brake drum and containing one piston, or two opposing pistons, cup seals, and a spring to hold the cup seals against the piston face.

CONT

As the pedal is depressed, it moves a piston within the master cylinder, forcing hydraulic fluid throughout the system and into cylinders at each wheel. Here, it causes the wheel cylinder pistons to move which, in turn, forces the brake shoes against the brake drums to retard their movement.

OBS

Record 5 2008-03-27

English

Subject field(s)
  • Aircraft Systems
OBS

Application of the brake pedal, which is linked to the master cylinder piston rod, causes the piston rod to push the piston forward inside the master cylinder casting. A slight forward movement blocks the compensating port, and the buildup of pressure begins. This pressure is transmitted to the brake assembly. When the brake pedal is released and returns to the "off" position, the piston return spring pushes the front piston seal and the piston back to full "off" position against the piston return stop. This again clears the compensating port. Fluid that was moved into the brake assembly and brake connecting line is then pushed back to the master cylinder by the brake piston which is returned to the "off" position by the pressure of the brake piston return springs. Any pressure or excess volume of fluid is relieved through the compensating port and passes back to the fluid reservoir. This prevents the master cylinder from locking or causing the brakes to drag.

French

Domaine(s)
  • Circuits des aéronefs

Record 6 2008-02-19

English

Subject field(s)
  • Aircraft Systems
DEF

The main component of a braking system consisting of the cylinder, piston and reservoir.

CONT

Some aircraft require wheel brake systems that operate with more fluid flow and higher fluid pressure than is within the capability of a simple master cylinder. In some types of aircraft, a compound master cylinder is used for this purpose. This type of master cylinder can deliver a large quantity of fluid at low pressure by means of relatively short pedal travel. It can also develop high operating pressure by means of moderate pedal pressure. This dual capability is achieved by means of two pistons : a large one for producing a large fluid flow with short travel; and a small one for developing high pressure from a lightly applied force.

OBS

The fluid is forced into the brake cylinder when braking is needed. Otherwise, it is stored when the brakes are not applied.

French

Domaine(s)
  • Circuits des aéronefs
