Easy to assembly.
Controller 40 can be the special controller of combined system of the present invention, it would however also be possible to employ car load control
Device processed.
The control program of combined system
As shown in figure 1, the combined system of the present invention includes air accumulator 60, this air accumulator 60 is provided with
Pressure sensor 61, air compressor machine 10 is connected to air accumulator 60 by gas circuit, and gas circuit is provided with check valve
12, controller 40 controls electromagnetic clutch 50 to engage according to the atmospheric pressure value that pressure sensor 61 detects
Or separate.
In this scheme, pressure sensor 61 can be used to the atmospheric pressure value in real-time detection air accumulator 60,
And the signal of this atmospheric pressure value is sent to controller 40, controller 40 can judge according to this atmospheric pressure value
Air compressor machine 10 is made to work the need of engaging electromagnetic clutch 50.
Generally, air accumulator 60 has the first setting atmospheric pressure value and the second setting atmospheric pressure value, the first setting gas
Pressure value is more than described second setting atmospheric pressure value.
When the atmospheric pressure value of pressure sensor 61 collection is less than second and sets atmospheric pressure value, controller 40 controls
Electromagnetic clutch 50 is switched to engagement state from released state, and motor 20 drives air compressor machine 10 to work,
There is provided air pressure by the check valve 12 in gas circuit in air accumulator 60, to ensure the brakes energy of vehicle
Enough normal works.
When the atmospheric pressure value of pressure sensor 61 collection reaches described first and sets atmospheric pressure value, controller 40
Control electromagnetic clutch 50 to be switched to released state from engagement state, air compressor machine 10 does not rerun, stop
Continue to provide air pressure to air accumulator 60.
In the present invention, in the gas circuit between air compressor machine 10 and check valve 12, also side is connected to air bleeding valve 13,
Controller 40 is used for controlling air bleeding valve 13 to open or close.By this air bleeding valve 13, can be to electromagnetism
Row buffering is entered in the unexpected joint of clutch 50 or separation, not only can reduce the mill of electromagnetic clutch 50
Damage additionally it is possible to buffering is because air compressor machine 10 works suddenly or stops and the steering operation to steering gear 70
The impact causing.
Specifically, as one kind preferred embodiment, when the atmospheric pressure value of pressure sensor 61 collection is little
When second sets atmospheric pressure value, controller 40 controls described electromagnetic clutch 50 to cut from released state first
Change to engagement state, then control air bleeding valve 13 to be switched to closure state from open mode again.In electromagnetism
Before clutch 50 engages, air bleeding valve 13 is in open mode, and therefore electromagnetic clutch 50 can be real
Existing unloaded joint, such that it is able to reduce the abrasion to electromagnetic clutch 50.Meanwhile, in electromagnetic clutch
Although air compressor machine 10 starts running after 50 joints, but the gas that air compressor machine 10 produces can pass through gas
On road, the other air bleeding valve 13 connecing is discharged, thus substantially and non-loaded, so also will not be to steering gear 70
Steering operation cause significantly to impact.
It is further preferred that after electromagnetic clutch 50 engages, described controller 40 controls described row
Air valve 13 is lentamente gradually switched to closure state from open mode, that is, realize the slow of air compressor machine 10 and add
Carry, rather than load suddenly, the steering operation such that it is able to preferably buffer to steering gear 70 causes
Impact, is reduced as far as the adverse effect to feel during Driver Steering Attention.
Making the time from open mode slowly switching to closure state for the air bleeding valve 13 can be as the case may be
Debugged, for example, when pneumatics acc power is larger, the time can be suitably longer, conversely, air compressor machine
When power is less, the time can be suitably shorter.As long as suitable slow of the handoff procedure of air bleeding valve 13
Some, air compressor machine 10 just can gradually load, and the working order of steering pump 30 will not become suddenly
Change, turn to oil pressure in in-line 31 also will not suddenly change, thus not the steering to steering gear 70
Operation causes substantially to impact and affects steering operation feel.
The control process above air compressor machine 10 being loaded is described.Similarly, unload in air compressor machine 10
It is also possible to by the reasonable control of air bleeding valve 13 and clutch is reduced with turning to steering gear 70 during load
Impact to operation.
Specifically, when the atmospheric pressure value of pressure sensor 61 collection reaches the first setting atmospheric pressure value, control
Device 40 controls air bleeding valve 13 to be switched to open mode from closure state first, then controls electromagnetic clutch again
Device 50 is switched to released state from engagement state.
Before separating in electromagnetic clutch 50, air bleeding valve 13 has already turned on, so air compressor machine 10
Load will be released by air bleeding valve 13, such that it is able to buffer the steering operation to steering gear 70
Impact.Afterwards, electromagnetic clutch 50 separates in the case of air compressor machine 10 zero load.
It is also preferable that before electromagnetic clutch 50 separates, controller 40 is also preferably to control exhaust
Valve 13 is lentamente gradually switched to open mode from closure state, that is, realize the slow unloading of air compressor machine 10,
Rather than Condition of Sudden Unloading, such that it is able to preferably buffer the impact of the steering operation to steering gear 70, to the greatest extent
Possibly reduce the adverse effect to feel during Driver Steering Attention.
Because air bleeding valve 13 is gradually to be switched to open mode from closure state, thus air compressor machine 10 is permissible
Gradually unload, the working order of steering pump 30 will not change suddenly, turn in in-line 31
Oil pressure also will not suddenly change, thus not causing substantially to impact and shadow to the steering operation of steering gear 70
Ring steering operation feel.
In the present invention, air bleeding valve 13 can use reversal valve, proportioning valve, switch valve, damping hole etc.
Form, as long as enabling above-mentioned functions, the invention is not limited in this regard.In addition, air bleeding valve 13

To lead to other air accumulator or other desired place.
As shown in figure 1, described steering pump 30 passes through steering in-line 31 is connected to steering gear 70, it is
The steering operation of steering gear 70 provides power-assisted.Rotary angle transmitter 72 is provided with steering gear 70, for examining
Survey the angular signal of steering gear 70, to judge whether steering gear 70 is in steering state.
As a kind of preferred embodiment, when the atmospheric pressure value of pressure sensor 61 collection reaches the first setting
During atmospheric pressure value, air compressor machine 10 needs to stop air accumulator 60 to be continued to provide air pressure, before this, first
Judge whether steering gear 70 is in steering state.
Specifically, when steering gear 70 being detected by rotary angle transmitter 72 being in non-steering state, control
Device 40 processed can control air bleeding valve 13 to be switched to open mode from closure state, then control again electromagnetism from
Clutch 50 is switched to released state from engagement state.This process can be identical with procedures described above,
Repeat no more.
When steering gear 70 is detected by rotary angle transmitter 72 and being in steering state, controller 40 can
To control air bleeding valve 13 to be switched to open mode from closure state, then steering gear 70 is waited to be returned to non-
After steering state, then electromagnetic clutch 50 is controlled to be switched to released state from engagement state.By this
Plant control mode, when steering gear 70 is in steering state, electromagnetic clutch 50 does not temporarily separate,
Air compressor machine 10 is avoided to quit work and affect steering operation feel.
It is further to note that in this embodiment, opening of air bleeding valve 13 can with closed manners
With identical with situation about being outlined above, lentamente gradually switch, with reduce as much as possible to turn to into
The impact of oil circuit 31.
In another preferred embodiment of the present invention, air accumulator 60 has the highest air pressure of setting
Value, second highest atmospheric pressure value and barometric minimum value, second highest atmospheric pressure value is less than highest atmospheric pressure value and is more than barometric minimum
Value.According to different situations, the first setting atmospheric pressure value above can select highest atmospheric pressure value or secondary
Hyperbar value.Preferably, second highest atmospheric pressure value can be chosen as the 75%-85% of highest atmospheric pressure value.
Specifically, when steering gear 70 being detected by rotary angle transmitter 72 being in non-steering state,
One sets atmospheric pressure value as highest atmospheric pressure value, and second sets atmospheric pressure value as barometric minimum value；When being passed by corner
When sensor 72 detects steering gear 70 and is in steering state, first sets atmospheric pressure value as second highest atmospheric pressure value,
Second sets atmospheric pressure value as barometric minimum value.
In other words, when steering gear 70 is in non-steering state, using highest atmospheric pressure value and barometric minimum
Value is judging air compressor machine 10 the need of work.And when steering gear 70 is in steering state, then utilize
Second highest atmospheric pressure value and barometric minimum value are judging air compressor machine 10 the need of work.
Air pressure in air accumulator 60 is higher, and the power needed for air compressor machine 10 works is also higher, i.e. load
Bigger；In addition, the steering oil-feed that during steering gear 70 work, turning velocity is faster, corner is bigger, required
Oil pressure in road 31 is also higher, and that is, the power needed for steering pump 30 is also higher.By above-mentioned side
Case, can make steering gear 70 and air compressor machine 10 peak power that offsets one from another is operated, such that it is able to select
Select the relatively small motor of design power 20, such that it is able to reduces cost.In addition, at steering gear 70
When steering state, the condition that air compressor machine 10 provides air pressure for air accumulator 60 is secondary in air accumulator 60
The load change of hyperbar value, rather than highest atmospheric pressure value, therefore air compressor machine 10 also can be smaller,
Thus the start-stop of air compressor machine also can be less to the impact turning to oil pressure in in-line 31, can be to greatest extent
Reduce the adverse effect even eliminating to steering operation feel.
Above the control program of combined system is described in detail.In addition, for motor 20
Speech, it equally can also be controlled by the controller 40 of the present invention, i.e. in preferred embodiment party
In formula, according to the working condition of the atmospheric pressure value in air accumulator 60 and steering gear 70, controller 40 is not only
