Increase what kinetic servo device was formed on the basis of brake fluid system, when driver takes brake operating, on brake pedal
Apply brake force, brake force is transferred on the piston of master cylinder by leverage, while servomechanism installation also works, and supply
Most braking energy, it is possible to reduce the manipulation strength of driver.If servo fails, then original hydraulic braking can still be made
With driver needs larger brake force that could meet the needs that vehicle is braked.The servo-type brake apparatus master used on car
There are two kinds of servo vacuum formula and Pneumatic servo type.
Vacuum servo formula servo brake between brake pedal push rod and master cylinder by installing vacuum booster additional
To provide power-assisted., it is necessary to vacuum source when vacuum booster provides power-assisted effect.Vacuum source on general car is by running
Engine provides, more convenient.For the car of non-internal combustion engine power plant vacuum pump is then needed to provide vacuum source.It utilizes
Engine, which provides vacuum source, two big defects, first, after engine misses, vacuum source disappears, and vacuum servo effect also disappears；Two
It is that the vacuum source that engine provides is related with its operating mode, vacuum servo effect may weaken.And when vacuum source is by dedicated true
When sky pump provides, number of parts on car can be increased, reduce the reliability of automobile and increase the difficult arrangement of enging cabin
And work noise.
Air pressure assisted formula servo brake provides power-assisted by installing air-assisted device additional, generally passes through band by engine
Transmission driving air compressor machine generates the air pressure that air-assisted device needs, correspondingly need to increase gas receiver, control valve, pressure regulator valve,
The attachmentes such as air cleaner, defroster, low pressure warning switch and air pipe line.Air pressure assisted formula servo brake system not only disappears
The power of engine is consumed, and since part is more, volume is larger, and the arrangement of enging cabin is relatively difficult.
Above braking feel is non-adjustable, and regenerative braking power is made of multiple, this causes driver to have different systems
Dynamic feel is, it is necessary to which development of new feel simulation mechanism device just adapts to require.
