The equipment method in other words of compressed air is supplied to commercial car.
Background technology
Different devices, especially brake are generally run by compressed air in commercial car.Compressor is set for this, should
Compressor is driven by the motor of vehicle, and is always operated together under normal circumstances.In order to ensure that continuous supply compression is empty
Gas, sets accumulator in addition, and the accumulator is filled with unnecessary compressed air.When accumulator is filled and with predetermined volume
During constant-pressure, by compressor compresses, just unwanted compressed air be discharged into environment so that compressor is not anti-
Actually in idle middle work in the case of pressure.The initiation of this process generally passes through the control of correspondingly load pressure
Outlet is carried out.
Brakes is in modern Commercial car because security reason is divided at least two loops.Whole compressed air system
Even manipulate four loops：Two loops are used for braking equipment, and a loop is used for EPB and a loop is used for
Other devices, such as spring.Each of these compressed air loops includes its respective accumulator.Pass through four-loop protection valve
Realize that compressed air is divided on four loops, the four-loop protection valve ensures that one in the loop has the pressure loss
When, other loops can continue to operation.
Because being configured with corrosion material in compressed air demand device, the compressed air used must be drying
's.Also it must prevent brakes from freezing in the winter time.In order to not damage sealing device and guider, compressed air also must quilt
Filtering.For such purpose, filtration drying box is usually provided with, it is output on different circuit and accumulator in compressed air
Before, guide the compressed air being compressed by the compressor to pass through the filtration drying box.Here, compressed air percolation filter diaphragm and
Dry particle.
It must regenerate the filtration drying box, to extend its use time.Therefore, guiding dry and clean sky
Air-flow passes through the filtration drying box against the filtering direction of script.Here, the particle is dried and filter film again
Piece is cleaned.Bear the compressed air of moisture and dirty grain and then be discharged into by exhaust openings actually no pressure in environment.
The palingenesis of filtration drying box is often implemented by single regenerative storage.
Electronic-controlled installation is generally responsible for the control of compressed-air supply system, and the electronic-controlled installation passes through different biographies
Sensor is obtained for the required information of control.Then, it is used for regulating system using the magnetic valve manipulated by electronic-controlled installation.
In addition, pressure-control valve is generally also required, so as to control institute functional.
However, the magnetic valve of the different controllable states with required quantity is very expensive or can not even purchased
.Therefore, the function is divided on multiple magnetic valves.But the use of multiple magnetic valves is also costly herein.
The content of the invention
The present invention is based on following tasks：So it is configured to supply the apparatus and method of compressed air to commercial car so that
Can be cost-effective in the case where not ignoring safety.
Task according to the present invention by the feature with claim 1 in other words claim 10 it is feature,
For equipment that compressed air is supplied to commercial car, method is solved in other words.Second can be saved by installing pressure-control valve
Magnetic valve, second magnetic valve must also be manipulated by electronic-controlled installation.The switching state of pressure-control valve herein directly or
The switching state of person and magnetic valve is in association dependent on the pressure in the outlet of at least one accumulator is led to.The pressure control
Valve processed can occupy following switching states, in the switching state, and the outlet for leading at least one accumulator passes through the electromagnetism
Valve is connected with filtration drying box on side, and the side is opposite with compressed air inlet.By this way, it is only necessary to Wei Yi electricity
Magnet valve, and electronic-controlled installation also only have to manipulate unique magnetic valve.
The other details of the present invention and advantage are drawn by dependent claims.
In order to avoid high cost, pressure-control valve as simple as possible is used.2/2-way valve is especially considered herein,
There are two interfaces (switching interface except being applied with switching pressure thereon) and the valve of two switching states.Most simple
Form in, the connection that described two interfaces are either connected with each other between (open position) or described two interfaces is separated
(closed position).A switching state in the two switching states is resting position, when the pressure being at switching interface is small
When pressure is switched, pressure-control valve occupies the resting position.If the pressure being at switching interface is increased to exceed switching
The value of pressure and the pressure-control valve is thus manipulated, the Vavle switching is into other switching states.
In the first embodiment of the equipment according to the present invention, using such Stress control 2/2-way valve, in the pressure
In power control 2/2-way valve, being connected in the inactive state not manipulated of pressure-control valve between two interfaces is closed.Cut
About 1bar below the maximum pressure of the equipment should be in by changing pressure.The valve is so integrated into the equipment：Leading to
The pressure that the exit of at least one accumulator is present is at the switching interface of pressure-control valve, and the pressure-control valve because
This is transformed into another switching state dependent on the pressure from a switching state.
Following Stress control 2/2-way valves are used in another embodiment, in the Stress control 2/2-way valve,
Being connected in the inactive state not manipulated of pressure-control valve between two interfaces is opened.In this embodiment just with
Showed on the contrary in the case of first embodiment.Herein, when at the pressure in exit for leading at least one accumulator
Switch below pressure, when being also less than maximum pressure about 1bar herein, during the valve is in an open position.In switching pressure
The valve is closed during the above.
Right rather than absolutely essential use Stress control 2/2-way valve.Be also using two-position three-way valve it is feasible, also
It is the valve that there are three interfaces but also there was only two switching states.This valve with three interfaces and two switching states
Constructed similar to the magnetic valve, but be not directed through electronic-controlled installation electric control, but by being at switching interface
Pressure control.Because the pressure is again by electronic-controlled installation by pressure sensor control, between electronic-controlled installation
Connecing influences the switching state of the pressure-control valve.
In the Stress control two-position three-way valve, there is also the resting position not manipulated, when the pressure being at switching interface
When power is in below switching pressure, the valve occupies the resting position, and the pressure at switching interface is critical more than this
When being worth (switching pressure), the valve occupies manipulation position.In this embodiment, between the two interfaces be connected to Stress control
In the inactive state not manipulated of valve open, wherein, one in two interfaces is connected with exhaust outlet, and another interface and
The side connection of filtration drying box, the side is opposite with compressed air inlet.
In the other embodiment with Stress control two-position three-way valve, between the two interfaces be connected to pressure control
Opened in the inactive state not manipulated of valve processed, wherein, one in two interfaces is connected with Stress control outlet.Described quiet
Another side herein also with filtration drying box of two interfaces is connected during stop bit is put, the side and compressed air inlet phase
It is opposed.
In the state (inactive state not manipulated) of no pressure, the switching state of pressure-control valve is by spring force come steady
It is fixed.For such purpose, the spring worked against switching pressure is set.The power of spring is so designed：Make on switching interface
, more than the pressure of switching pressure overcome spring force, and the Vavle switching is manipulated to it in position.The intensity of spring in
Be for switch pressure adjustment be conclusive.
In order to regenerate filtration drying box, it is necessary to guide dry and cleaning compressed air against proper flow direction
Through filtration drying box.For such purpose, it is necessary to make filtration drying box, in face of compressed air inlet side be vented.Cause
This, sets the other pressure-control valve with two interfaces and two switching states, the other pressure-control valve is in loading
Compressed air inlet is set to be connected with exhaust outlet in the manipulation state of pressure.This other pressure-control valve passes through first pressure
Control valve (being combined with magnetic valve) is manipulated.
Run for supplying the equipment of compressed air to commercial car with the rated pressure determined, the rated pressure is not dependent on
Same condition.But the rated pressure is not understood to fixed value, and is understood to a scope, pressure in the apparatus can
Change between the upper and lower bound of the scope.The palingenesis of filtration drying box is introduced in the method according to the invention,
In this method, magnetic valve is switched in following states more than the upper limit of rated pressure or below the lower limit of rated pressure,
The compressed air produced in a state by compressor is discharged into environment, and pressure-control valve switches simultaneously in a state
Into following states, the outlet that at least one accumulator is led in a state is connected with the side of filtration drying box, the side with
Compressed air inlet is opposite.The magnetic valve controlled by electronic-controlled installation is only needed by this way.Make to introduce regeneration
With then must only being briefly less than or beyond rated pressure.Using the deviation of rated pressure, to draw pressure-control valve
To following switching states, the switching position of the switching state combination magnetic valve can realize the palingenesis of filtration drying box.
Compressed air that is clean and drying is needed to be used for the palingenesis of filtration drying box.The compressed air is from least
Taken in one accumulator.Palingenesis is implemented by the compressed air from accumulator by pressure-control valve, wherein, pressure
Force control valve at pressure below maximum pressure 0.5 between 2bar when switch.The scope ensures, the method according to the invention
It can be implemented with two kinds of flexible programs.Or the switching pressure of pressure-control valve is in below rated pressure, then also specified
The following switching solenoid valve of pressure, for starting palingenesis；Or the switching pressure of pressure-control valve is located at more than rated pressure
And also in rated pressure above switching solenoid valve, for starting palingenesis.Especially in the latter case, regeneration is being introduced
Also the distance sufficiently large relative to maximum pressure is retained during effect so that never threaten the security of system.
In order to implement the regeneration of filtration drying box, it is necessary to guide dry and clean compression against common direction
Air passes through the filtration drying box.Therefore, the pressure in filtration drying box, opposite with compressed air inlet side must
The pressure in compressed air inlet side must be higher than.Hence it is advantageous to make compressed air inlet pass through other pressure-control valve
Exhaust, the other pressure-control valve is by first pressure control valve or passes through electromagnetism Vavle switching.

According to the present invention compressed air feedway basic structure figure 1 illustrates.The control of feedway is by electricity
Sub- control device 1 is responsible for.The electronic-controlled installation obtains the measured value of pressure sensor 2, and the pressure sensor is asked for
The pressure for leading to accumulator 7 in mouthful.
In addition, the two-position three-way valve 3 of electromagnetism is manipulated by electronic-controlled installation 1.By the valve, Stress control outlet 16 or
Person is connected with exhaust outlet 6 or with the outlet 7 for leading to accumulator.
First pressure control 2/2-way valve 8 is by being steered leading to pressure present in the outlet 7 of accumulator.Switching
Pressure should be in about 1bar below the rated pressure of the equipment, and the valve becomes from the first switching state under the switching pressure
Into the second switching state.
Compressed air inlet 4 is supplied by the compressor being not shown herein.The compressed air of inflow was guided through
Filter drying box 5.By the second check valve 12, then compressed air cleaned and dried reaches the outlet for leading to accumulator

Control 2/2-way valve 9 to be vented compressed air inlet 4 by second pressure, two are controlled in the second pressure
In the two-way valve of position, the compressed air inlet is connected with exhaust outlet 6.The manipulation of second pressure control valve 9 passes through first pressure
Control valve 8 is carried out in combination with magnetic valve 3.
All three valves have two switching states：Resting position, these valves are expressed in the resting position by spring；With
Manipulate position, these valves or by electromagnetic force (solenoid) or by aerodynamic force (compressed air) be extruded to the manipulation position
In putting.If not only magnetic valve 3, and pressure-control valve 8 and 9 can then implement filtration drying box 5 in its manipulation position
Palingenesis.In this case, compressed air from unshowned accumulator herein by lead to accumulator outlet 7,
Magnetic valve 3, first pressure control valve 8, the first check valve 10 and throttling arrangement 11 flow to filtration drying box 5.Compressed air along
Usual direction penetrates filtration drying box 5 and is discharged into by second pressure control valve 9 and exhaust outlet 6 in environment.Against
When usual direction passes through filtration drying box 5, the dirty grain adhered in filtering material is carried, and receive in dry granular material
The moisture of absorption.
To be explained in detail below figure 1 illustrates embodiments of the invention function.If necessary to be produced by compressor
Raw compressed air, then magnetic valve 3 is in the position shown in figure ia.First pressure control valve 8 is also at the position shown
In.It is coupled to by magnetic valve 3 on exhaust outlet 6 and therefore without on-load pressure Stress control outlet 16.
If should not implement the palingenesis of filtration drying box 5, magnetic valve 3 is maintained in the position shown until reaching volume
The upper limit of constant-pressure.In first pressure control valve 8 at about 1bar predetermined switching pressure below the upper limit of rated pressure
At switching interface, the predetermined switching pressure makes first pressure control valve 8 move in manipulation position.Reaching the upper of rated pressure
In limited time, first pressure control valve 8 is shut off.
Rated pressure is controlled by electronic-controlled installation 1 by pressure sensor 2.If reaching the upper limit of rated pressure, electricity
Magnet valve 3 is electronically controlled device 1 and is switched to manipulation position.This state is shown in fig. ib.Now by magnetic valve 3, logical
Pressure present in outlet 7 to accumulator is in Stress control outlet 16.This control pressure causes, and is provided by compressor
Compressed air be not transported to by compressed air inlet 4 in supply arrangement further, but be discharged into environment.
By magnetic valve 3 and the control pressure being in Stress control outlet 16, exist in the outlet 7 for leading to accumulator
Pressure be always held at by control device 1 in the range of rated pressure.If it means that in the outlet 7 for leading to accumulator
In pressure the lower limit of rated pressure is gone straight down to by consumption of compressed air, then it is static that magnetic valve 3 again switches to its
In position so that Stress control outlet 16 couples with exhaust outlet 6 and is therefore no pressure again.In such state,
Compressor provides compressed air by compressed air inlet 4 into supply arrangement again.But, the lower limit of rated pressure is still located
More than the switching pressure for pressure-control valve 8 so that in pressure during normal operation in the outlet 7 of accumulator is led to
It is always held in following levels, prevents first pressure control valve 8 from returning in its resting position in the level so that first
Pressure-control valve 8 is constantly in manipulation position, i.e., in closed position.
Electronic-controlled installation 1 continuously asks for the air capacity for passing through filtration drying box 5 to compress from compressor during running.
Thus set out herein：The moisture content and pollution level of air do not change.But the two parameters also can be by passing accordingly
Sensor is measured.Under any circumstance, the load of filtration drying box 5 is asked for or estimated by electronic-controlled installation 1.If reached
Certain load, it is necessary to regenerate filtration drying box 5.For such purpose, it should guide clean and drying in the opposite direction
Compressed air passes through filtration drying box 5.
If electronic-controlled installation 1 is so determined：Corresponding big air capacity has been directed through filtration drying box 5, and
It must regenerate the filtration drying box, then magnetic valve 3 is electronically controlled the manipulation position that device 1 keeps showing in fig. ib
In, drop to even in leading to the following degree of the pressure in the outlet 7 of accumulator below the lower limit of rated pressure, first pressure
Control valve 8 returns to its resting position.First pressure control valve 8 is switched in its open position by this way.Leading to storage
Pressure present in the outlet 7 of depressor is in Stress control outlet 16 in such state so that compressor is by the pressure of generation
Contracting air is discharged into environment.But, leading to pressure present in the outlet 7 of accumulator now by first pressure control valve
8th, the first check valve 10 and throttling arrangement 11 are also on the pipeline between the check valve 12 of filtration drying box 5 and second.
But by first pressure control valve 8, the pressure is now simultaneously also in the switching entrance of second pressure control valve 9
Locate, and the second pressure control valve is switched to it and manipulated in position, i.e., in open position.Thus, compressed air inlet 4 with
Exhaust outlet 6 is coupled and is therefore vented.This state of supply arrangement is shown in fig. 1 c.
By be in filtration drying box 5, with the pressure of the opposite side in compressed air inlet 4, from leading to accumulator
The compressed air that is clean and drying for exporting 7 and coming is extruded through filtration drying box 5.Here, filtration drying box 5 is dried
And cleaned.Environment is discharged to from the next air that is moist and bearing dirty grain of filtration drying box 5 by exhaust outlet 6
In.
If the pressure in the outlet 7 of accumulator is led to drops to minimum, magnetic valve 3 by control device again
Switch back in its resting position.Pipe section between present first check valve 10 and first pressure control valve 8 passes through magnetic valve 3
It is connected and is vented with exhaust outlet 6 so that second pressure control valve 9 is also again switched in its resting position, i.e., it is closed
In closed position.Because present Stress control outlet 16 is also no pressure, compressor provides compressed air to compressed air again
On entrance 4.
If when the pressure in leading to the outlet 7 of accumulator reaches minimum pressure, the palingenesis of filtration drying box is also
It is not over, then the palingenesis is implemented with multiple stages.At predetermined pressure at first pressure control valve 8 before,
Switching solenoid valve 3 is used for the next stage of palingenesis.Because so in the first pressure control valve also in opening
During resting position, magnetic valve 3 makes the pressure led in the outlet 7 of accumulator be connected to first pressure control valve 8, filtration drying box
5 palingenesis can soon continue to implement.At the end of the palingenesis of filtration drying box 5, lead to the outlet 7 of accumulator
In pressure be just electronically controlled device 1 and heightened again to the upper limit of rated pressure by magnetic valve 3.
Figure 2 illustrates the embodiment of the change of the equipment according to the present invention.Fig. 1 first pressure control 2/2-way valve
8 control 2/2-way valve 13 to substitute by the first pressure of the change with opposite switching state herein.Fig. 1 pressure-control valve
8 be to open in its inactive state not manipulated, and the static shape that the first pressure control valve 13 of Fig. 2 change is not manipulated at it
State is to close.
Therefore, the palingenesis of filtration drying box is carried out somewhat differently in this embodiment.In first pressure control
In valve 13, predetermined switching pressure is in more than the upper limit of rated pressure, but below the maximum pressure of permission.Normal
During operation, therefore first pressure control valve 13 is constantly in the resting position not manipulated.Electronic-controlled installation 1 is by manipulating electricity
Magnet valve 3 remains open to pressure at the outlet 7 of at least one accumulator approximately constant in the range of rated pressure, without herein
Manipulate first pressure control valve 13 and guide in its open position.
If being now to regenerate filtration drying box, electronic-controlled installation 1, which is improved, is leading to going out at least one accumulator
Pressure at mouth 7 exceedes rated pressure until the switching pressure more than pressure-control valve 13.Thus, first pressure control valve 13 is cut
In the open position for changing to its manipulation.
More than the switching pressure of pressure-control valve 13, magnetic valve 3 is electronically controlled device 1 and is incorporated into its manipulation until now
In position.In such state, the pressure existed at the outlet 7 for leading at least one accumulator is in Stress control outlet again
On 16 so that the compressed air of generation is discharged into environment by compressor.Leading to simultaneously at the outlet 7 of at least one accumulator
Pressure pass through on the always on switching interface to second pressure control valve 9 of first pressure control valve 13.The second pressure
Control valve is moved in manipulation position so that is started entrance 4 and is vented by exhaust outlet 6.Come from and lead at least by this way
The compressed air of the outlet 7 of one accumulator can pass through magnetic valve 3, first pressure control valve 13, the first check valve 10 and section
Stream device 11 is directed until on filtration drying box 5, and is guided through the filtration drying box to exhaust outlet 6.
If leading to the pressure at the outlet 7 of accumulator again less than the switching pressure of first pressure control valve 13, institute
State the resting position that valve returns to its closing.Therefore palingenesis is interrupted.In order to which compressed air inlet 4 connects with compressor again
Connect, magnetic valve 3 is electronically controlled device and is switched in its resting position and Stress control is exported 16 exhausts.
Fig. 3 shows substitution first pressure control 2/2-way valve 8 or 13 and uses first pressure to control two-position three-way valve 14
Feasibility.This valve equally has three interfaces and two switching states such as magnetic valve 3.In the inactive state not manipulated
In, the interface being connected with the first check valve is vented by exhaust outlet 6.According to this state of the equipment of the present invention and in Fig. 2
In equipment state it is substantially equivalent.Function also corresponds to the equipment being illustrated in Figure 2.Therefore, the function is in this position
It should not explain again.
In the equipment according to Fig. 4, Fig. 3 first pressure controls two-position three-way valve 14 by changing with opposite switching state
The first pressure control two-position three-way valve 15 of change is replaced.Fig. 3 first pressure control valve 14 is in its inactive state not manipulated
Make the section exhaust between the valve and the first check valve 10, and the first pressure control valve 15 of Fig. 4 change is not manipulated at it
Inactive state in realize connection between the check valve 10 of magnetic valve 3 and first.Therefore, the arrangement states shown are same as
Arrangement states in Figure 1A.Because in this case, function can be compared with the function of Fig. 1 equipment, so herein
The palingenesis of filtration drying box 5 should not also illustrate again.
Figure 5 illustrates embodiment in, second pressure control valve 9 not by first pressure control valve 8, but directly lead to
Magnetic valve 3 is crossed to manipulate.Once switching solenoid valve 3, cuts leading to pressure present in the outlet 7 of accumulator and be also at herein
At alias.This manipulation type of second pressure control valve is existed in the embodiment shown in Fig. 2 to 4 naturally.
Figure 6 illustrates manipulation first pressure control valve embodiment can also be converted to it is all before explanation implementations
In example.In this embodiment, outlet 7 of the switching interface of first pressure control valve not directly with leading to accumulator is connected, and
It is 16 be connected with Stress control outlet, and can be by this way always when magnetic valve 3 is also switched, first pressure is controlled
The switching interface of valve is just introduced in in the switching state required for the palingenesis of filtration drying box 5.Figure 6 illustrates
The manipulation of the second pressure control valve set in Figure 5, but the manipulation shown herein in Fig. 1 to 4 is also feasible.
