Description
The present invention relates to a kind of vehicle electric compressed air system of the preamble according to claim 1.
A kind of as can be known pneumatic type motor vehicle braking system from WO 98/47751 A1, this system is provided with: a compressor; At least one consumption of air loop, such as all foot brakes loop, brake circuit, a low pressure subsidiary loop and a high tension loop on the other hand, wherein all loops are provided with pressurized air storage container and all instruction valves.Be equipped with all first electrically operated valves between compressor and at least one consumption loop, these valves are closed under the normality of outage; And be equipped with one second electrically operated valve between compressor and subsidiary loop, this valve is opened under the normality of outage.All valves are driven by an electronic control unit.The exit end of all first valves in all consumption of airs loop is communicated with through the exit end of all boiler check valve with second valve, and this valve is opened under the normality of outage.As when consuming one of loop when needing pressurized air, for example during the storage container hypotony,, come the compensating air demand by compressor immediately just corresponding valve is started by control unit, meanwhile, second valve closing of subsidiary loop.The fault of compressor can cause pressure decay, and this can be examined by control unit, and this control unit is with valve closing or make it keep closed condition, to keep the pressure in the loop.One pressure regulating valve has determined stress level.When the pressure regulating valve et out of order, discharge too high pressure by an overpressure valve.The pressure sensor monitoring loop.Second valve that open during by normality in all loops and the boiler check valve that is connected in the upstream, loop obtain air and supply with.When electric system is malfunctioning, under all valves promptly are in the normal state.At this moment, compressor continues operation and supplies air by second valve of opening under the normal state in the subsidiary loop to the loop, and the pressure of system is determined by the low-pressure safety valve in the subsidiary loop.If any a defective valve, can supply air with boiler check valve to relevant loop by the valve in the subsidiary loop.Because each consumes the loop and all is equipped with a pressurized air storage container, existing systems is very complicated.
By Deutsche Reichspatent 100004091 a C2 compressed air supply system that is used for compressed air system as can be known, the control pilot valve and that this system configuration has a multiloop protective valve, a pressure regulator, to be used to supply to have the supply pipe and in compressed-air actuated multiloop protective valve loop can be used for control presssure regulating control and set shifter by the compressor, of a pneumatic shifter control is installed in the flow regulating valve between control cock and the shifter.Each loop all is equipped with a pressurized air storage container.Pilot valve is controlled and/or is regulated by an electronic control unit and/or pressure regulation unit.Pressure in pressure sensor monitoring loop and the supply pipe.
In the vehicle that disposes the compressed air brake system, well-known, the pressurized air storage container meets European drg standard (EU BrakeDirective) for front axle and rear axle brake circuit are provided with mutually independently.In addition, the pressurized air storage container also is used for other pressure air consumer, an AIRMATIC Dual Control for example, thereby the adverse effect the when function that guarantees brake system can not be subjected to this type of additional compressed air consumer operation.Being provided with independently in the compressed air system in existing a plurality of pressurized air consumption loop, the cost of pressurized air storage container spends very high.
The objective of the invention is to design a kind of compressed air system of the above-mentioned type, except brake circuit, many pressurized air storage containers that is used for consuming as the additional compressed air in Pneumatic Suspension loop and so on the loop can fully phase out, and needn't worry again has negative effect to brake circuit.
This target can be realized by the present invention according to claim 1.
Advantage of the present invention and favourable improvement have illustrated in the appended claims.
The present invention consumes the loop configuration electrically operated valve at each, preferably selects electromagnetic valve for use.Compressed air system designed according to this invention, cost-saved, because additional compressed air consumer, especially Pneumatic Suspension loop no longer need to dispose the pressurized air storage container, comprise relevant assembly.Obviously, the storage container in foot brake loop can not save.According to design of the present invention, the cost of total system reduces.The complexity of installing reduces.Needing under the situation of pressure, as long as the brake-pressure of brake circuit meets rules, additional compressed air consumes loop, especially Pneumatic Suspension loop basically can be by foot brake loop air feed, for this reason, must open the electromagnetic valve in the Pneumatic Suspension loop of closing under the normality, this is because the electromagnetic valve in foot brake loop is opened under normal conditions, perhaps in other words, opens under the normality of outage.Like this, hang in the loop, have only when electronically controlled Pneumatic Suspension loop (ECAS) transfer valves just when needing pressurized air, the switching frequency of electromagnetic valve closed minimizing under the normality in the pressurized air that does not have the pressurized air storage container.System safety and reliability are improved.Because it is electromagnetic valve is closed in normal running, imperceptible by the caused reaction in Pneumatic Suspension loop in brake circuit.
To on the basis of accompanying drawing, be described in more details below, the figure shows an example of the compressed air system of being invented the present invention.
In the accompanying drawings, the effective solid line of pressure fluid represents that the electric appliance circuits with dashed lines is represented.
There is shown one and have the compressed air system 2 that pressurized air supply section 4 and a pressurized air consume part 6.Pressurized air supply section 4 comprises a compressor 7, a compressor control device 8 and a dry air part 10.
But pressurized air consumes part 6 and is provided with pressurized air distribution pipe 14, a plurality of electric actuation electromagnetic valve 16,18,20,22,24 and a plurality of pressurized air consumption loop 26,28,30,32,34,36,38 with recovery spring, and these consume loops and supply pressurized air by electromagnetic valve.
One pressurized air supply pipe 40 leads to distribution pipe 14 from compressor 7 by a filter 42, an air dryer 44 and a boiler check valve 46, and distribution pipe 14 has all branched pipes 48,50,52,54,56 that lead to all electromagnetic valves.Compressed air tube 58,60,62,64,66 leads to the consumption loop through all electromagnetic valves.Pipe 62 is provided with branched pipe 62 ' and 62 ", they lead to loop 30 and 32, at pipe 62 " locate also to be placed with boiler check valve 68.Be equipped with a voltage limiter 70 at supply pipe 52 places.The pipe 54 that leads to electromagnetic valve 22 forms branch in the downstream of voltage limiter 70.Pipe 64 is provided with branched pipe 64 ' and 64 ", they lead to loop 34 and 36.
Pressure in pressure sensor 72,74,76,78,80,82 monitoring all consumption loops and the distribution pipe 14, and each pressure is passed to the electronic control unit 84 of all electromagnetic valves of direct control as pressure signal.
Consume loop 26,28 and can be the foot brake loop.Consume loop 30 and can be the trailer braking protection valve loop, in this case, two tubes is arranged usually: a supply pipe and a brake pipe that leads to trailer.Consume loop 32 and can be the hand braking loop that has spring accumulator.Consume loop 34 and 36 and can be secondary consumption loop, such as operator's compartment suspension, door controller etc., in other words, the assembly that all and brake circuit have nothing to do.Consumption loop 38 is designed to the high tension loop of an AIRMATIC Dual Control (representing with bellows).One AIRMATIC Dual Control needs high pressure usually, because the Pneumatic Suspension bellows have very big volume and relative higher pressure usually.
Foot brake loop 26,28 is provided with the pressurized air reservoir vessel 90,92 of conform European standard (EU Directive) 98/12.
Compressed air system of the present invention can be saved the pressurized air storage container in loop 30,32,34,36, especially the Pneumatic Suspension loop 38.For example, as long as the braking function or the braking maneuver of foot brake loop 26 and 28 are not weakened, can allow to consume the loop to other pressurized air and carry out air feed by foot brake loop (loop 26 and 28).
By a pipe 40 ', compressor 7 is controlled by compressor controller 8 machineries (pneumatic).Compressor controller 8 comprises the less electromagnetic valve of a Nominal Width 94, and this electromagnetic valve can be switched by electronic control unit 84.As shown in the figure, it is opened under the normal condition of outage, and at this moment, compressor 7 starts.If close compressor 7, for example when all being full of pressurized air in all consumption loops, control unit 84 is the position of switching solenoid valve 94 just, makes and can be closed by pipe 40 ' by pressure-actuated compressor.If electromagnetic valve 94 is switched to off-position, for example when a consumption loop needs pressurized air, once more electromagnetic valve 94 is switched to graphic normal condition, thus, pipe 40 ' is opened, and compressor 7 restarts.
Dry air part 10 comprises that one has the electromagnetic valve 100 of less Nominal Width, the import 102 of this electromagnetic valve is communicated with distribution pipe 14, and its outlet 104 by this electromagnetic valve links to each other with the shut off valve 106 of air operated control, this valve that dams is communicated with the supply pipe 40 of compressor 7, is used as the exhausr port of air dryer.
When electromagnetic valve 100 was switched to connected state, compressor 7 no longer supplied inflation in consuming the loop, but passes through valve 106 to atmospheric exhaust.At the same time, dry air then by distribution pipe 14 (being connected) with the storage container 90,92 in foot brake loop through electromagnetic valve 100, flow regulating valve 108 and boiler check valve 110 air dryer 44 of flowing through, make its desiccant regeneration, and then flow into atmosphere through filter 42 and valve 106.
Label 112 expressions one overpressure valve.
Electromagnetic valve 16,18,20,22,24 is by control unit 84 control, and the electromagnetic valve 16 to 22 that consumes loop 26 to 34 is in opening under the normal condition of outage, and the electromagnetic valve 24 in Pneumatic Suspension loop 38 is in closing under the normal condition of outage.Also can use all guiding controlled electromagnetic valves.Pressure in the loop is directly monitored at the electromagnetic valve place by pressure sensor 72,74,76,78,80.Pneumatic Suspension loop 38 is by control setup 120 (being also referred to as an ECAS) electrical control, and this control setup is connected with electronic control unit 84 by a data line 122.
During as the pressure decay that consumes in loop, for example loop 30 (the trailer braking protection valve loop) when one, pressurized air can be supplied by opening electromagnetic valve in foot brake loop 26 and 28, the pressure that voltage limiter 70 can consume secondary in the loop 30 to 36 is adjusted to than the pressure in foot brake loop 26 and 28 (for example 10.5bar) lower level, for example 8.5bar.Pneumatic Suspension loop 38 is closed by electromagnetic valve 24, and not with other circuit communication.It has higher pressure usually, for example is 12.5bar.
If the storage container in the Pneumatic Suspension loop 38 is saved, as mentioned above, and as because the layout and the structure of the special electromagnetic valve of describing become possibility, have only the capacity and the less ultimate capacity existence of consumer of the storage container in foot brake loop.If an a spot of leakage takes place in not having the AIRMATIC Dual Control of storage container, need carry out frequent adjustment by electromagnetic valve 24 usually.Because the Nominal Width of electromagnetic valve 24 is bigger usually, it is just very complicated to regulate algorithm accordingly, therefore wishes to have only when the Pneumatic Suspension loop needs pressurized air really just electromagnetic valve to be opened.Like this, just might omit above-described pressure control.
Under the compressed-air actuated situation of needs, for example, because the stress level regulatory function, control setup 120 sends a pressurized air request signal by data line to electronic control unit 84, and this control setup is connected with electronic control unit 84 by data line 122.Whether meet given value in order to the pressure in check stop loop 26 and 28 (or flow, air quality or energy).Like this as situation, just control unit 84 switches to open position with electromagnetic valve 24 from the normal position of closing so, thereby by the electromagnetic valve often opened 16,18 set up with storage container 90,92 between be communicated with.Then, Pneumatic Suspension loop 38 is put on the air to Pneumatic Suspension loop 38 by the pressurized air storage container 90,92 of brake circuit 26,28 electromagnetic valve 16,18 through opening.If the pressure decay in the brake circuit that is recorded by pressure sensor 72,74 is below specific value, then electronic control unit 84 can detect this situation, this control unit is closed the electromagnetic valve 24 in Pneumatic Suspension loop 38 in view of the above and by compressor control device 8 conversion electromagnetic valves 94, is started compressor 7.Compressor is to the brake circuit air feed.When storing the pressure that reaches given in the brake circuit, electronic control unit 84 switches to open position once more with the electromagnetic valve 24 in Pneumatic Suspension loop, thereby the Pneumatic Suspension loop is constantly inflated by brake circuit or its pressurized air storage container 90,92.The pressure that this circulation inflation of being undertaken by brake circuit proceeds to Pneumatic Suspension loop 38 always ends when reaching given value.The pressure request signal disappears, and electromagnetic valve 24 is closed once more, and brake circuit obtains inflation once more.After this, electromagnetic valve 94 is switched to the normal condition of exhaust once more, with close compressor 7, and opening conduits 40 '.
Compressor is usually only to brake circuit 26,28 air feed.If needed, also can in the case,, can close the electromagnetic valve 16,18 in the brake circuit to Pneumatic Suspension loop air feed according to the air pressure in the brake circuit.Since the pressure in the relevant consumption loop 30 to 36 is limited by voltage limiter 70, the electromagnetic valve 20 and 22 of secondary circuit stays open state so.
Already mentioned as previously mentioned such, Pneumatic Suspension loop 38 has the pressure rating that is higher than other loop usually; Yet comparatively speaking, it is not frequent to the demand of pressure, and therefore, according to the present invention, it is closed under the state of outage.Even need, it can (megasecond or part second) not need pressurized air yet in a very of short duration time, and this has just provided permission and electronic control unit 84 is set up a certain limit time of getting in touch; Therefore the Pneumatic Suspension loop is closed under normal condition.Loop 30 to 36 is by the storage container 90 and 92 air feed of foot brake loop 26 and 28, and opens under the off-position of valve 16,18,20 and 22 when normal operation.
Except pressure, also might monitor other state variable, for example consume air rate, air quality and energy in loop and the distribution pipe.
