The separation type brake master cylinder assembly that possesses active and passive hydraulic booster has initially, normally works and the three kinds of states that lost efficacy, and below the each several part effect of separation type brake master cylinder assembly and mode of operation is further described.
One, initial condition
When brake system does not power on, separation type brake master cylinder assembly, in initial condition, now, is not stepped on brake pedal 201, and motor-drive pump 104 is not worked, and normal-open electromagnetic valve 107 is opened, and high pressure accumulator 106 is not set up high pressure; Boosting piston 302, master cylinder first piston 303 and master cylinder the second piston 305 respectively under the second pull back spring 306 effects of master cylinder the first pull back spring 304 and master cylinder in integrated form master cylinder body 301 rightmost of movement travel, i.e. initial position separately; Pedal sense simulator push rod 203 is the rightmost in pedal sense simulator cylinder body 204 under 205 effects of pedal sense simulation spring; Pedal sense simulation normally closed solenoid valve 206 is closed, and pedal sense simulation normally open solenoid valve 207 is opened, and whole hydraulic braking subsystem everywhere pressure is zero.
After brake system powers on, separation type brake master cylinder assembly enters initial condition, and this stage time length is shorter, and pedal sense simulation normally closed solenoid valve 206 is opened, and pedal sense simulator cylinder body 204 is communicated with oil cabinet 101; Pedal simulated feel normally open solenoid valve 207 cuts out; Normal-open electromagnetic valve 107 is closed, motor-drive pump 104 extracts braking liquid and pump into high pressure accumulator 106 after the second check valve 105 from oil cabinet 101 after the first check valve 103, and braking liquid (high pressure oil) acts on master cylinder first piston 303 and boosting piston 302 by the second through hole C2; Master cylinder first piston 303 and master cylinder the second piston 305 move to left under high pressure oil effect, seal respectively third through-hole C3 and fourth hole C4, and master cylinder back cavity and master cylinder ante-chamber and oil cabinet 101 disconnect, and set up high pressure; Because pedal sense simulation normally open solenoid valve 207 cuts out, boosting piston 302 under integrated master cylinder body 301 restrictions in static; Brak control unit gathers hydraulic pressure transducer 108 signals, maintains high pressure accumulator 106 pressure stabilitys by controlling motor-drive pump 104, for braking maneuver afterwards provides initiatively power-assisted.
Two, normal working
When brake system is normally worked, in the time that chaufeur is stepped on brake pedal 201, pedal sense simulation normally closed solenoid valve 206 is in open mode, pedal sense simulator push rod 203 moves to left under brake pedal 201 effects, braking liquid enters oil cabinet 101 by the first through hole C1 pedal sense simulation normally closed solenoid valve 206 of flowing through, meanwhile, pedal sense simulation spring 205 applies antagonistic force to pedal sense simulator push rod 203, and good brake pedal feel is provided.Master cylinder ante-chamber is connected with hydraulic control unit with the 7th through hole C7 by the 6th through hole C6 respectively with master cylinder back cavity; Brake system is normally worked in engineering, and motor-drive pump 104 and high pressure accumulator 106 provide high hydraulic brake fluid for the pressure of four brake wheel cylinders regulates constantly.
By gathering pedal displacement sensor 202 information, can obtain driver's brake operating intention and braking requirement, and pressure of wheel cylinder regulates by hydraulic control unit, i.e. brake pedal operation has realized decoupling zero with brake-pipe pressure.Taking Electro-hydraulic brake system as example, according to vehicle running state and information of road surface, reasonably distribute regenerative brake power and hydraulic braking force, no matter vehicle electrical liquid composite braking system, in states such as pure regenerative brake, Electro-hydraulic brake or pure hydraulic brakings, can both provide good brake pedal feel.The design of change brake pedal feel simulation spring 205, can be different target vehicle different brake pedal feels is provided.
In the time that braking procedure finishes, remove the treadle effort that acts on brake pedal 201, brake pedal feel simulation spring 205 makes pedal sense simulator push rod 203 get back to initial position, and braking liquid flows back to pedal sense simulator cylinder body 204 from oil cabinet 101 through pedal sense simulation normally closed solenoid valve 206 and the first through hole C1.
Three, failure state
If when electric system lost efficacy (as unexpected power down) or high-voltage power supply can not set up high pressure (as high pressure accumulator is revealed), brake system enters failure state.Motor-drive pump 104 quits work, and normal-open electromagnetic valve 107 is opened, and the frequent open form electromagnetic valve 107 of the high hydraulic brake fluid of high pressure accumulator 106 flows back to oil cabinet 101; Pedal sense simulation normally closed solenoid valve 206 is closed, and pedal simulated feel normally open solenoid valve 207 is opened, and connects pedal sense simulator cylinder body 204 be respectively connected integrated form master cylinder body 301 with fifth hole C5 by the first through hole C1; Master cylinder first piston 303 and master cylinder the second piston 305 are got back to initial position respectively under master cylinder the first pull back spring 304 and master cylinder the second pull back spring 306 effects, and master cylinder ante-chamber and master cylinder back cavity communicate by the 6th through hole C6 and the 7th through hole C7 hydraulic control unit respectively.
In the time that chaufeur has braking requirement, by stepping on brake pedal 201, pedal sense simulator push rod 203 compression pedal sensation simulation springs 205, braking liquid is acted on to boosting piston 302 by flow through pedal simulated feel normally open solenoid valve 207 and fifth hole C5 of the first through hole C1, the pressure producing acts on master cylinder first piston 303 and master cylinder the second piston 305 successively, set up high pressure at master cylinder ante-chamber and master cylinder back cavity, and braking liquid stream is pressed into four brake wheel cylinders, ensure the brake-pressure of four brake wheel cylinders, realized the emergency braking under failure state.After boosting piston 302 moves to left, because boosting piston 302 is different with pedal sense simulator push rod 203 sectional areas, brake pedal force is amplified, under failure state, can realize the passive power-assisted of brake pedal.
