Pressure increases, and promotes T-shaped piston movement, so that the first cavity pressure increases, further promotes first piston and second piston, will make
Hydrodynamic is pressed into ABS or ESP by outlet one and outlet two and (not identified in figure), so as to realize skidding.
Because first piston net sectional area is larger, T-shaped piston net sectional area is smaller, therefore in active boost process
In, the larger pressure oscillation in booster cavity can be reduced, and reduced the axial fluctuation of first piston, finally made brake Reeb
It is dynamic to reduce, the ride comfort of brake weight is improved, the riding experience of user is improved.
First piston net sectional area is bigger than the net sectional area in push rod, it is assumed that the net sectional area of first piston is to push away
N times of bar net sectional area, then the axial force of push rod only has the 1/N of first piston axial force, is passing through brake pedal lever
Further power is reduced than (T), therefore the final power fed back on pedal only has the 1/N/T of first piston axial thrust.
Alternate brake
There is one section of S space between push rod and T-shaped piston.When brakes active brake fails, driver steps on system
Dynamic pedal, push rod is axially moved, after S distances have been moved, and push rod and T-shaped piston rigid contact continue to step on brake pedal, then pushed away
Bar promotes T-shaped piston movement, finally produces brake force.
