The adjustment barrel (not shown) of the amount of the coolant of wheel.For example, the feature of the closing cylinder is in the document for representing applicant
It is illustrated in WO2015/004548.
According to above-described embodiment, based on the appearance of conditions certain during vehicle use, to electric drive 4 and/or possible
Electromagnetism pulley implements electronic control.
In normal configuration, electromagnetism pulley is not powered on and electric drive 4 is closed, and therefore, impeller 2 only passes through electromagnetism pulley
It is mobile, i.e., it is moved by the rotation of mechanical axis 300.
For example, when starting the vehicle, if engine is still cold (so-called " preheating " configuration), electromagnetism pulley is swashed
It is living, to release the movement on mechanical axis 300 when electric drive 4 stops.Therefore, impeller 2 is remain stationary motionless, and liquid does not exist
It is recycled in circuit, and motor quickly preheats.
According to another example, under fully loaded transportation condition (such as when vehicle breakdown trailer or climbing, usually under the low speed
(therefore, engine speed is lower)), electric drive 4 is activated so that the rotation speed of electronic axle 400 is greater than by thermo-mechanical drive
3 and mechanical axis 300 caused by speed so that impeller 2 rotates under the speed as caused by electronic axle 400.
Advantageously, in this configuration, the first one-way clutch 51 is detached from the impeller 2 in rotation from mechanical axis 300, thus
Reduce the quality that electric drive 4 drags in rotation.
, if coolant is still very warm, electric drive 4 is activated after using vehicle according to another example, so as to
So that impeller 2 is kept rotation (this stage is known as " rear operation ").In this way, impeller 2 rotates under desired speed, and thermo-mechanical drive 3
It does not work completely, this is because vehicle motor has been switched off.Specifically, for example, electromagnetism pulley no power, it is for rotation
It is not required for the movement of axis.Also in this case, the first one-way clutch 51 makes the impeller 2 in rotation from machinery
Axis 300 is detached from, to reduce the quality that electric drive 4 drags in rotation.
Therefore in general, (regardless of thermo-mechanical drive 3 whenever needing to enhance cooling capacity related with engine speed
How), electric drive 4 is just activated.
For example, in one embodiment (pump group 1 includes the thermo-mechanical drive 3 with " the classical pulley " of mechanical type, because
This cannot be controlled electronically, and it is still cold above-mentioned " preheating " stage that above-mentioned throttle valve, which is in wherein engine, and is needed
Heated as quickly as possible), the amount of the coolant in circulation is adjusted by the positioning of control throttle valve.
Pump group according to the present invention innovatively meets the cooling of engine and requires and overcome disadvantages mentioned above.
Firstly, advantageously, the flexibility of pump group according to the present invention is very high, this is because it according to actual needs without
It is the electricity availability of engine speed or system to respond the cooling requirement of vehicle.That is, advantageously, pump group demonstrates
It is particularly suitable for comprehensively managing the amount of coolant in cooling system (for example, other vehicles by management in addition to the engine
The cooling of component (such as turbine set)), to avoid the need for having specific electrodynamic pump to make predetermined amount in these components
Coolant is mobile, has thus striven for additional space in enging cabin.
Advantageously, moreover, pump group is extremely compact, and size is small, makes it uniquely suited for being contained in starting for motor vehicles
In cabin.
Such as advantageously, impeller (and blade wheel chamber with spiral case) more compact and size is unlikely to excessive, and with
(wherein the size of impeller is usually excessive, to make up the limited function of the poor flexibility and electrodynamic pump of mechanical pump for known pump group
Rate) it compares, always operated under the conditions of optimum performance.
Another is advantageous in that, electric drive and thermo-mechanical drive are directly bonded on impeller (such as without centre
Axis), this simplifies the structure of pump group, the pump group is dimensionally more compact compared with the solution of the prior art.
Another advantageous aspect includes that pump group needs a small amount of dynamic sealing: specifically, it is only necessary to which a dynamic is close
Sealing is by impeller housing and thermo-mechanical drive housing apart.Advantageously, the motor of pump group of the invention can be set
Wet type rotor, there is no need to special dynamic sealings, but need for it to be sealed off against out with coolant liquid.
Advantageously, the design of thermo-mechanical drive and electric drive is quite simplified and can be optimized by designer；
Advantageously, electromagnetism pulley (if what is be arranged has) does not need special design update；Advantageously, the rotor of motor is direct
It is mounted in impeller shaft, without special shielded bearing, therefore limits the axial occupied area of rotor.
Advantageously, moreover, the transition from electric drive to thermo-mechanical drive and reversed transition be by these unidirectionally from
Clutch mechanically operates.Therefore, advantageously, the e-management of pump group is very simple.
Advantageously, even if engine is in the state that gear connects, pump group also can be avoided cooling action, for example,
Under the conditions of " preheating ", heat engines are suitable.
At another advantageous aspect, pump group has " emergency protection " feature；In fact, the feelings to break down in electric drive
Under condition, since there are thermo-mechanical drive and the second one-way clutch, pump group continues the movement for ensuring impeller.
According to another advantageous aspect, pump group (i.e. tail-off) under " after operation " state is operating.Have
Sharp ground can power, to save electric power under the conditions of " rear operation " to avoid to electromagnetism pulley.
Another is advantageous in that compared with standard mechanical pump, which has more limited power absorption.
Advantageously, impeller may be produced that have included one-way clutch (in fact, one-way clutch is in its moulding process
In be plugged into).
In addition, the kinematic chain between thermo-mechanical drive, electric drive and impeller is quite simplified.
Advantageously, moreover, the second one-way clutch allows rotor matching impeller by what thermo-mechanical drive rotated
It is not rotated by axis in setting；Therefore, magnetic friction will not be generated (rotor-stator group also works not as generator).
Advantageously, moreover, the first one-way clutch and the second one-way clutch can be according to electric drives and thermo-mechanical drive
Required different movements are to select different characteristics.
Advantageously, electric drive absolutely not dynamic sealing and the bearing of support drive shaft, thus provide higher
Electrical efficiency and wider range electric operation.
Another advantageous aspect also resides in the versatility of pump stack design, the especially versatility of respective housings design, this
A little shells can be designed as needed, to accommodate and/or support electric drive and thermo-mechanical drive, so that corresponding axis
It is operably connected to impeller.
Another advantageous aspect is, wherein the water chamber for accommodating the rotor of motor is effectively filled by coolant,
This is because its be installed on electronic axle allow coolant effective recycling, and then by central tube sucking cooling
Agent.
Obviously, those skilled in the art can modify to above-mentioned pump group to meet possible requirement, all these to repair
Change and is included in the protection scope being determined by the claims that follow.
In addition, each modification for being described as belonging to possible embodiment can come independently of described other embodiments
It realizes.
