As shown in Figure 1, a kind of embodiment according to the present invention, discloses the combination system of a kind of vehicle braking and steering
System mainly includes air compressor machine 10, motor 20, steering pump 30 and controller 40, wherein the motor 20 has both ends output
Motor shaft, one end of the motor shaft are connected to the steering pump 30, and the other end is connected to the sky by electromagnetic clutch 50
Press 10, the controller 40 is for controlling the engagement of electromagnetic clutch 50 or separation.
Specifically, one end of motor shaft is connected to steering pump 30, for driving the steering pump 30 to work, with to vehicle
Steering system fuel feeding, provide power-assisted for the steering operation of vehicle；The other end is connected to air compressor machine 10 by electromagnetic clutch 50,
The electromagnetic clutch 50 engagement or separation are controlled by controller 40, drives to the property of can choose air compressor machine 10 to work, and root
Air pressure is provided to the braking system of vehicle according to needs.More specifically, steering pump 30 is used to provide hydraulic oil to diverter 70, it is empty
Press 10 is used to provide air pressure to air accumulator 60.
Motor 20 can generally also be controlled by controller 40.Certainly, the operation of motor 20 can also be controlled by other
Mode processed or guard's valve control.
By this embodiment, air compressor machine 10, electromagnetic clutch 50, motor 20 and steering pump 30 can close cloth
It sets, thus entire combined system is compact-sized, noise is small, and transmission efficiency and reliability are higher.In addition, the motor of motor 20
The oil pump of shell 22 and steering pump 30 installation shell 32 can be removably joined together to constitute one by fastener
Monolithic case can guarantee that the structure of the two is more compact in this way, save the arrangement space on chassis, and easy to assembly.
Controller 40 can be the dedicated controller of combined system of the invention, can also use entire car controller.
The control program of combined system
As shown in Figure 1, combined system of the invention includes air accumulator 60, pressure sensor is provided on the air accumulator 60
61, air compressor machine 10 to air accumulator 60, is provided with check valve 12 in gas circuit, controller 40 is according to pressure sensor by air circuit connection
The atmospheric pressure value of 61 detections is engaged or is separated to control electromagnetic clutch 50.
In this scheme, pressure sensor 61 can be used to the atmospheric pressure value in real-time detection air accumulator 60, and by the air pressure
The signal of value is sent to controller 40, and controller 40 can be according to the atmospheric pressure value to determine whether needing to engage electromagnetic clutch 50
Air compressor machine 10 is set to work.
In general, air accumulator 60 has the first setting atmospheric pressure value and the second setting atmospheric pressure value, the first setting atmospheric pressure value is greater than institute
State the second setting atmospheric pressure value.
When the atmospheric pressure value that pressure sensor 61 acquires is less than the second setting atmospheric pressure value, controller 40 controls electromagnetic clutch
50 are switched to engagement state from discrete state, and motor 20 drives air compressor machine 10 to work, by the check valve 12 in gas circuit to gas storage
Air pressure is provided in tank 60, to guarantee that the braking system of vehicle can work normally.
When pressure sensor 61 acquire atmospheric pressure value reach it is described first setting atmospheric pressure value when, controller 40 control electromagnetism from
Clutch 50 is switched to discrete state from engagement state, and air compressor machine 10 does not rerun, and stops continuing to provide air pressure to air accumulator 60.
In the present invention, also other in the gas circuit between air compressor machine 10 and check valve 12 to be connected to exhaust valve 13, controller 40
It opens or is closed for controlling exhaust valve 13.By the exhaust valve 13, can unexpected engagement to electromagnetic clutch 50 or
Separation buffered, not only can reduce the abrasion of electromagnetic clutch 50, additionally it is possible to buffering due to air compressor machine 10 suddenly work or
Person stops and impacts caused by the steering operation of diverter 70.
Specifically, as a preferred embodiment, when the atmospheric pressure value that pressure sensor 61 acquires is set less than second
When atmospheric pressure value, controller 40 controls the electromagnetic clutch 50 first and is switched to engagement state from discrete state, then controls again
Exhaust valve 13 is switched to closed state from opening state.Before the engagement of electromagnetic clutch 50, exhaust valve 13 is in the open state,
Therefore unloaded engagement may be implemented in electromagnetic clutch 50, so as to reduce the abrasion to electromagnetic clutch 50.Meanwhile in electromagnetism
After clutch 50 engages, although air compressor machine 10 starts running, the gas that air compressor machine 10 generates can be connect by other in gas circuit
Exhaust valve 13 be discharged, thus it is substantially and non-loaded, so will not cause significantly to rush to the steering operation of diverter 70
It hits.
It is further preferred that the controller 40 controls the exhaust valve 13 from beating after the engagement of electromagnetic clutch 50
Open state is slowly gradually switched to closed state, that is, realizes the Slow loading of air compressor machine 10, rather than load suddenly, so as to
Preferably to buffer the impact caused by the steering operation of diverter 70, it is reduced as far as to during Driver Steering Attention
The adverse effect of feel.
The time that exhaust valve 13 is slowly switched from opening state to closed state can be debugged as the case may be, example
Such as, when air compressor machine power is larger, the time can be appropriate longer, conversely, the time can be appropriate short by one when air compressor machine power is smaller
A bit.As long as the handoff procedure of exhaust valve 13 is appropriate slowly, air compressor machine 10 can be loaded gradually, the fortune of steering pump 30
Turning situation will not change suddenly, turn to in-line 31 in oil pressure also will not suddenly change, thus will not be to diverter 70
Steering operation cause obviously impact and influence steering operation feel.
The control process loaded above to air compressor machine 10 is described.It similarly, can also be with when air compressor machine 10 unloads
Reduce the impact of the steering operation to diverter 70 by the reasonable control to exhaust valve 13 and clutch.
Specifically, when the atmospheric pressure value that pressure sensor 61 acquires reaches the first setting atmospheric pressure value, controller 40 is controlled first
Exhaust valve 13 processed is switched to opening state from closed state, then controls electromagnetic clutch 50 again from engagement state and is switched to separation
State.
Since before the separation of electromagnetic clutch 50, exhaust valve 13 is had already turned on, so the load of air compressor machine 10 will pass through
Exhaust valve 13 and be released, so as to buffer the impact of the steering operation to diverter 70.Later, electromagnetic clutch 50 exists
It is separated in the case where 10 zero load of air compressor machine.
It is also preferable that controller 40 is also the preferred exhaust valve 13 that controls from closure before the separation of electromagnetic clutch 50
State is slowly gradually switched to opening state, that is, realizes the slow unloading of air compressor machine 10, rather than Condition of Sudden Unloading, so as to
The impact to the steering operation of diverter 70 is preferably buffered, is reduced as far as to feel during Driver Steering Attention
Adverse effect.
Because exhaust valve 13 is gradually to be switched to opening state from closed state, so that air compressor machine 10 can be unloaded gradually,
The working order of steering pump 30 will not change suddenly, turn to in-line 31 in oil pressure also will not suddenly change, thus
The steering operation of diverter 70 will not be caused obviously to impact and influence steering operation feel.
In the present invention, the forms such as reversal valve, proportioning valve, switch valve, damping hole can be used in exhaust valve 13, as long as can be real
Existing above-mentioned function, the invention is not limited in this regard.In addition, the exhaust outlet of exhaust valve 13 can generally be directly communicated to atmosphere.
Alternatively, the exhaust outlet of exhaust valve 13 can also lead to other air accumulator or other desired place.
As shown in Figure 1, the steering pump 30 is connected to diverter 70 by turning to in-line 31, it is turning for diverter 70
Power-assisted is provided to operation.Rotary angle transmitter 72 is provided on diverter 70, for detecting the angular signal of diverter 70, with judgement
Whether diverter 70 is in steering state.
As a preferred implementation manner, when the atmospheric pressure value that pressure sensor 61 acquires reaches the first setting atmospheric pressure value,
Whether air compressor machine 10 needs to stop to continue to provide air pressure to air accumulator 60, before this, first determine whether diverter 70 in steering
State.
Specifically, when detecting that diverter 70 is in non-steering state by rotary angle transmitter 72, controller 40 can be with
It controls exhaust valve 13 and from closed state is switched to opening state, then control electromagnetic clutch 50 again and be switched to point from engagement state
From state.This process can be identical as procedures described above, repeats no more.
When detecting that diverter 70 is in steering state by rotary angle transmitter 72, controller 40 can control exhaust valve
13 are switched to opening state from closed state, then wait diverter 70 be returned to non-steering state and then control electromagnetism from
Clutch 50 is switched to discrete state from engagement state.Pass through this control mode, when diverter 70 is in steering state, electromagnetism
Clutch 50 does not separate temporarily, and air compressor machine 10 is avoided to stop working and influence steering operation feel.
It is further to note that in this embodiment, the opening and closing mode of exhaust valve 13 can with above
The case where description, is identical, i.e., slowly gradually switches, to reduce the impact to in-line 31 is turned to as much as possible.
In another preferred embodiment of the invention, air accumulator 60 has the highest atmospheric pressure value of setting, secondary high gas
Pressure value and barometric minimum value, secondary hyperbar value are less than highest atmospheric pressure value and are greater than barometric minimum value.According to different situations, above
In first setting atmospheric pressure value can choose highest atmospheric pressure value or secondary hyperbar value.Preferably, secondary hyperbar value can choose
For the 75%-85% of highest atmospheric pressure value.
Specifically, when detecting that diverter 70 is in non-steering state by rotary angle transmitter 72, the first setting air pressure
Value is highest atmospheric pressure value, and second sets atmospheric pressure value as barometric minimum value；It is detected at diverter 70 when by rotary angle transmitter 72
When steering state, first sets atmospheric pressure value as time hyperbar value, and second sets atmospheric pressure value as barometric minimum value.
In other words, when diverter 70 is in non-steering state, sky is judged using highest atmospheric pressure value and barometric minimum value
Whether press 10 needs work.And when diverter 70 is in steering state, then using time hyperbar value and barometric minimum value come
Judge whether air compressor machine 10 needs work.
Air pressure in air accumulator 60 is higher, and air compressor machine 10 works, and required power is also higher, i.e., load is bigger；In addition,
Turning velocity is faster when diverter 70 works, corner is bigger, and the required oil pressure turned in in-line 31 is also higher, that is, turns to
Power needed for oil pump 30 is also higher.Through the above scheme, diverter 70 and air compressor machine 10 can be made to offset one from another peak work
Rate works, so as to select the relatively small motor 20 of design power, so as to reduce cost.In addition, turning to
When device 70 is in steering state, air compressor machine 10 is the secondary hyperbar value that the condition that air accumulator 60 provides air pressure is in air accumulator 60,
Rather than highest atmospheric pressure value, therefore air compressor machine 10 load variation also can be smaller, thus the start-stop of air compressor machine to turn into
The impact of oil pressure also can be smaller in oil circuit 31, can maximally reduce the unfavorable shadow even being eliminated to steering operation feel
It rings.
Above the control program of combined system is described in detail.In addition, for motor 20, equally
Can controller 40 through the invention controlled, that is, in a preferred embodiment, according to the atmospheric pressure value in air accumulator 60
With the working condition of diverter 70, controller 40 can not only be controlled exhaust valve 13 and electromagnetic clutch 50, can be with
