Specific embodiment
Referring to attached drawing, simple integrated type electrical brake fluid system, including integrated package 1, the integrated package 1 use aluminium alloy
Material, 1 top of integrated package are equipped with the connector A 20 for connecting with brake fluid oil pot 2, and the brake fluid oil pot 2 is by connecing
Head A is connect with master cylinder 3, and 1 side of integrated package is equipped with the lumen pore 18 for accommodating brake master cylinder piston and compressed spring,
The piston of the master cylinder 3 is connect with brake pedal 4, and the piston 31 and compressed spring 32 of the master cylinder 3 are in integrated package
Lumen pore 18 in be able to carry out axial movement, the master cylinder 3 is by 302 groups of the first brake chamber 301 and the second brake chamber
At wherein including corresponding return spring and piston in each chamber, predominantly driver generates hydraulic needed for braking.
The master cylinder 3 forms brake fluid circuit by the piping connection in integrated package with hydraulic braking module 5, hydraulic
Brake module 5 flows in the pipeline of master cylinder 3 and is successively arranged accumulator 6, check valve 7 and plunger pump 8, depressurizes in wheel wheel cylinder
When, extra brake fluid can flow into accumulator, and the effect of the check valve is to guarantee that brake fluid can only flow to plunger from accumulator
Pump.
1 front end of integrated package is equipped with the connector B 19 for connecting with motor 9, and the plunger pump 8 is connect with motor 9,
In the present embodiment, the plunger of the plunger pump is connected to motor by eccentric wheel, and motor band movable eccentric wheel rotates, bias rotation
It is dynamic that plunger is driven to move back and forth, the brake fluid in accumulator can be sucked out and be discharged into master cylinder.
1 rear end of integrated package is connected with ECU module 10.
In the present embodiment, the integrated package bottom end is equipped with the connector C for connecting with wheel braking wheel cylinder, the braking
First brake chamber 301 of master cylinder is connected to wheel braking wheel cylinder A 11 and wheel braking wheel cylinder B 12 respectively, the braking master
Second brake chamber 302 of cylinder is connected to wheel braking wheel cylinder C 13 and wheel braking wheel cylinder D 14 respectively, therefore, described hydraulic
Brake module 5 includes 4 normally open solenoid valve 51 and 4 normally closed solenoid valves 52,4 normally open solenoid valves and 4 normally closed electricity
Magnet valve is by the way that in interference fit indentation integrated package, 1 pair of normally open solenoid valve and normally closed solenoid valve cooperate and control 1 wheel braking
Wheel cylinder by the conducting to solenoid valve and disconnects the hydraulic size of control wheel braking, to realize anti-lock function.
Correspondingly, there are two the accumulator 6, check valve 7 and plunger pump 8 are all provided with, it is respectively arranged on the first brake chamber
In 301 pipelines 21 being connected to wheel braking wheel cylinder A 11 and wheel braking wheel cylinder B 12, the second brake chamber 302 and wheel system

Enter in integrated package, hydrostatic sensor is able to detect the variation of hydraulic pressure of pipe line, if there is situations such as leakage, hydraulic variation is fed back
To ECU.
Conventional brake:
When needing to increase brake force, driver applies pressure to brake pedal, and master cylinder generates brake fluid pressure, at this time
Solenoid valve is failure to actuate (normally open solenoid valve conducting, normally closed solenoid valve close) in braking system, brake fluid by normally open solenoid valve into
Enter in wheel braking wheel cylinder, generates brake fluid pressure.
ABS anti-lock function:
(1) be pressurized: when driver applies pressure to brake pedal, which vehicle ECU judges by the information that sensor acquires
Wheel needs to be pressurized or remain unchanged, and the corresponding normally open solenoid valve of wheel braking wheel cylinder for needing to be pressurized is failure to actuate, and master cylinder produces
Raw brake fluid flows into wheel braking wheel cylinder, increases the brake force of wheel.
(2) pressure maintaining: on the basis of step (1), when ECU judges that one of wheel becomes by the signal that sensor acquires
When locking, ECU makes its corresponding normally open solenoid valve energization movement, and normally closed solenoid valve is failure to actuate, oil circuit cutting where the wheel.
It there will be neither brake fluid in the corresponding wheel cylinder of the wheel to flow into and do not have brake fluid outflow, so the wheel braking wheel cylinder
Middle brake fluid pressure remains unchanged.
(3) depressurize: on the basis of step (2), the signal judgement that ECU is acquired by sensor is thought, wheel braking wheel cylinder
In it is hydraulic excessively high, when need to depressurize, corresponding normally open solenoid valve is remained off, normally closed solenoid valve energization movement be on shape
State, corresponding wheel cylinder brake fluid flow through normally closed solenoid valve, flow into accumulator, and the brake fluid pressure of wheel reduces.
Repeatedly by step (1), step (2), step (3) movement, ABS anti-lock function can be realized.
(4) oil extraction: when ECU judgement needs for brake fluid in accumulator to be discharged, direct current generator movement.Direct current generator drives
By plunger pump reciprocating action finally accumulator is discharged in brake fluid by eccentric wheel, is back to master cylinder.Due to there is check valve
Presence, brake fluid can only one-way flow.
Failure mode:
In the case where the complete power loss of hydraulic actuator, direct current generator can not be acted, and solenoid valve keeps original state, normally opened electricity
Magnet valve tends to remain on, and normally closed solenoid valve keeps off state, and driver, which can increase wheel by master cylinder, to brake
It is hydraulic, driving is braked, but ABS anti-lock function cannot achieve at this time.
