13。
A kind of master cylinder with output pressure preconditioning function as shown in Figure 1, according to the stroke of push rod 14, determine from
The pressure being output in fluid reservoir in pipeline, 14 stroke of push rod is longer, and opening is bigger, and output pressure is higher.
The displacement that piston assembly in the past 7 relatively moves is come the pressure that determines uninterrupted to determine from A to B in chamber, also
It is the pressure that cup 20 arrives preceding liquid storage cylinder；The pressure in c chambers is determined with the latus rectum between push rod 14 and back cavity channel 15, that is, after
The pressure of liquid storage cylinder；
The differential piston group 21 of inertia proportion valve is located at the front of inertia ball 4, inertia ball 4 and valve function.Poor diameter is lived
The both ends of plug group 21 be two with one heart but the cylinder of diameter not etc..
The starting stage that output pressure p 2 in input pressure p 1 and preceding brake chamber in preceding liquid storage cylinder grows simultaneously,
Inertia ball 4 is maintained at that rear extreme position is motionless, and the oil inlet A of cup is communicated with preceding liquid storage cylinder, preceding brake chamber, thus p2=p1,
The hydraulic action at the both ends of differential piston group 21 differs at this time.
Certain certain value ps is arrived in input pressure p 1 in current liquid storage cylinder, the simultaneous growths of output pressure p 2 in preceding brake chamber
When, when the oblique bearing surface that inertia ball 4 is θ along inclination angle is rolled into pressing differential piston group 21 upwards, preceding liquid storage cylinder and preceding braking
Chamber is just mutually isolated, and the stopping of differential piston group moves to right.Hereafter, it is small that the input pressure p1 for continuing to increase is applied to differential piston group 21
On end, differential piston group 21 initially moves off inertia ball 4, to there is a small amount of brake fluid to enter preceding brake chamber, the pressure of brake chamber before making
Power p2 is also increased.After inertia proportion valve works, the increment of the output pressure p2 of preceding brake chamber is less than preceding liquid storage cylinder
Input pressure p 1 increment, however, inertia ball 4 be again switched off before access between brake chamber and preceding liquid storage cylinder, differential piston
Group 21 according to area or diameter square ratio come reduce lead to before brake chamber outlet brake-pipe pressure.
According to the size of severity of braking, after adjustment in brake chamber output pressure P2 size so that back cavity loine pressure root
It is adjusted according to deceleration, deceleration is big, and the transfer of rear axle axle load is big, and required back cavity loine pressure is small, so defeated in brake chamber after adjustment
It is small to go out pressure P2, conversely, output pressure P2 is big in brake chamber after then, closer to ideal braking distribution when vehicle braking.
There is one-way flow regulating valve assembly in piston assembly 12 afterwards, under the action of one-way valve spring 17, one-way flow tune
It saves valve assembly to close, rear piston assembly 12 generates under the action of the thrust of push rod 14 in additional pressure output to pipeline.
Preceding brake-line leak, rear cavity pressure drop under stress because one-way flow regulating valve assembly closes pressure effect
It is closed after 4MPa, cavity pressure is not less than 6MPa after guarantee, ensure that the emergency braking ability of braking system.
Rear brake duct road leaks, preceding cavity pressure because inertia proportion valve assembly one-way movement characteristic, pressure substantially without reduction,
To ensure the emergency brake ability of vehicle.
When kinetic pump is input to pressure is relatively low in fluid reservoir when, pedal force is input to by push rod 14 in piston, before promotion
Piston assembly 7 and rear piston assembly 12, generate certain pressure, compensate lower loine pressure.
Particular embodiments described above, pair present invention solves the technical problem that, technical solution and advantageous effect carry out
It is further described, it should be understood that the above is only a specific embodiment of the present invention, is not limited to this
Invention, all within the spirits and principles of the present invention, any modification, equivalent substitution, improvement and etc. done should be included in this hair
Within bright protection domain.
