Description
Technical field
The present invention relates to a kind of automobile brake equipment with valve, this valve is arranged between first and second chamber, can make fluid direct into second chamber the inside selectively and this valve is furnished with prime and main for direct fluid by this valve from first chamber.
Background technology
In the automobile brake equipment in modern times, use self-priming pump, its sucking-off fluid and for example can continue to carry from for example be placed in the reservoir vessel on the main brake cylinder in order to set up brake-pressure at wheel braking.Have high pressure change-over valve (HSV) between the aspiration end of reservoir vessel and pump, it can close the pipeline from reservoir vessel to the pump aspiration end selectively.When the high pressure change-over valve of such setting was closed, self-priming pump can vacuumize the position between high pressure change-over valve and the pump intake under certain running state.When then opening the high pressure change-over valve, the hole of pipeline is full of by the fluid from main brake cylinder (part is effectively moved) or reservoir vessel (complete effectively operation) for this power section that vacuumizes.Therefore be full of such impact type ground and realize that it causes noise and is attached to the pedal reaction of the brake pedal of main brake cylinder.Except this reaction of not expecting is reacted to produce the object sound wave on the motor of external pump automatically, because the same impact type of the load torque of pump ground changes.
Strong relatively pedal reaction does not correspond to the normal characteristic of automobile brake equipment and therefore may stimulate the driver owing to the equilibrium of pressure process that enters into pump suction tube the inside from the high pressure change-over valve with relative loud pulsed noise.Therefore to avoid this specific character of automobile brake equipment.
Summary of the invention
The objective of the invention is, provide have valve, the automobile brake equipment of for example high pressure change-over valve, this valve for example can direct into fluid to constitute the pump suction tube of second chamber selectively from the reservoir vessel that constitutes first chamber.In the problem that can avoid the above-mentioned impact type equilibrium of pressure process under all running statees on this valve and especially avoid danger at some running state limitation function.
According to this purpose of the present invention by being achieved according to automobile brake equipment of the present invention, it has the valve that is arranged between first chamber and second chamber, can make fluid be directed to second chamber the inside selectively and this valve is furnished with prime and main for direct fluid by this valve from first chamber, it is characterized in that, main constitutes when opening prime automatically with opening but described prime external control constitutes with opening, and described main is opened motion automatically and constituted according to the difference of pressure between two chambers when opening prime.
Be furnished with prime and main this like this according to valve described in the automobile brake equipment of the present invention, make the prime external control constitute and main constitutes when opening prime automatically with opening with opening.This according to valve of the present invention in main after its prime is handled, open, this be need not special control indication.Therefore can make valve completely through-flow in order to handle valve from beginning.But open by through-flow with at first only making the prime external control.Then according to environmental aspect and especially when prime is opened main just open.
Especially for the problems referred to above situation of automobile brake equipment the motion of opening automatically according to the main of valve of the present invention is constituted when opening prime according to the difference of pressure between two chambers with high pressure change-over valve.When the pressure in first chamber is less than or equal to pressure in second chamber, then preferably makes according to the main of opening automatically of the present invention and open.Also maximum allowable difference of pressure of preliminary election is on purpose avoided the above-mentioned impact type equilibrium of pressure process that is occurred at present thus reliably.
Also can select or additionally make the motion of opening automatically of main when opening prime, to constitute according to the absolute pressure in first chamber and/or second chamber.Therefore for example can more than adjustable main brake cylinder pressure, prime be opened, and main be opened automatically after reaching corresponding stress level in the space between second chamber or high pressure change-over valve and pump.Opening pressure and can pass through the preliminary election of main spring in this main.Then main is opened at once when main brake cylinder pressure is opened pressure less than corresponding main.Therefore can realize the very short period and avoid ineffective time to a great extent.
This external according in the automobile brake equipment of the present invention advantageously, main open automatically when motion influence time at interval, begin to open motion according to this time gap main.Guarantee in this way, at first open prime in all cases.
Preferably when opening motion automatically according to main of the present invention, influence speed in addition, carry out with this speed main and open motion.In this way can be when connecting prime the opening of damping main, make thus main open lentamente and make thus second chamber slowly but be full of reliably.
This function preferably realizes by the main with closure body, and this closure body at least can be hydraulically in some running state or the motion of viscous damping ground.The purpose that has that can realize the space between second chamber or high pressure change-over valve and the pump by damping hydraulic pressure or viscous is full of, and avoids the noise do not expected or the unaccommodated characteristic of automobile brake equipment brake pedal thus under all running statees.
Hydraulic damping at this main closure body preferably constitutes by chamber, in prime fluid is discharged from this chamber rapidly.The fluid of realizing is discharged according to the appearance of the pressure in second chamber and when this pressure is very low thus, and is correspondingly quick.The fluid of discharging correspondingly causes the effect that damping increases and causes the second desired chamber especially slowly to be full of thus rapidly.
The hydraulic damping of main closure body preferably constitutes by a chamber in addition, and fluid can only flow into this chamber the inside lentamente in prime motion back.Fluid begins according to the pressure in second chamber to entering still of this chamber, can realize the damping relevant with difference of pressure equally thus.
According to this chamber emptying of the pressure in second chamber and/or be full of in simple especially mode and can constitute by non-direct acting auxiliary valve basically.This auxiliary valve can be for example seal ring or boiler check valve, and it guarantees rapid emptying chamber when connecting prime, but makes chamber at opposite through-flow direction back seal.
In this way can be in that for example spring controlled opening more than the pressure do not produce impact type equilibrium of pressure process reliably on according to valve of the present invention by main according to the present invention, but its prime is opened.And open the following main of pressure always at once along with prime is opened in main.Open according to the main of viscous damping of the present invention and to allow the pressure of opening of main to connect relatively lowly because reach main open pressure the time impact type ground by this main.But main is because the damping of its viscous strengthens the through flow cross section area relatively lentamente.Avoid pulsed noise and impact type pedal travel in this way reliably.Can simplify valve control according to the present invention in addition, because this valve only needs to obtain the unique and common constant stream of opening in order to handle.
