Description
The present invention relates to a kind of fluid pump that is used for internal-combustion engine, it has a motor, this motor has a rotor and a stator that is arranged in the motor housing, wherein, described rotor is arranged on the live axle at least antitorquely, one is fixed on the active wheel on the live axle, at least one guide vane wheel, this guide vane wheel is arranged on the back of described active wheel on the flow direction of the fluid that will carry, and one around motor housing, the pump casing of active wheel and guide vane wheel, and two axial end portions on this pump casing are provided with a pressure tap respectively opposed to each other and a suction is taken over, between the first motor housing part of the pump casing of radially outer part and, ribs is set one in inner radial, described motor housing part is radially surrounded motor, wherein, the described pump casing part that is positioned at radially outer designs integratedly with motor housing part and ribs.
The fluid pump that is used for internal-combustion engine especially is used as the coolant pump of coolant circuit.Though directly related with the rotating speed of motor existence in the past, and described pump passes through the band transmission or chain-driven drives, and uses electric coolant pump rotating speed adjustable, that have the slit pipe more and more in the motor of renewal, so that realize the heat management in modern times.Therefore can avoid the surplus of transmission power, thereby can, such as after cold start-up, heat internal-combustion engine quickly.Quantity delivered can cooling power according to actual needs be regulated.
For example MTZ Nr.11 2005 (872-877 page or leaf) discloses a kind of pump of this type.This electric coolant pump comprises an EC-motor as drive unit, and has a head that has axial entrance and tangentially export.Yet, parts as used herein, and especially housing parts is too big concerning the power consumpiton of pump, therefore must use bigger drive motor.
Therefore, US2002/0106290 A1 discloses a kind of semiaxis streaming electrofluid pump, when the power consumpiton of motor was identical, using this semiaxis structure to make this motor was that the rotating speed that reaches bigger can be designed to be littler, thereby is issued to identical quantity delivered in littler structure.This electrofluid pump has the motor of sealing fully, in the design of the outside of described motor one guide vane wheel is arranged.Yet, on flow direction, see, be formed with in the guide vane wheel back and prevent to set up the obstacle electrically contact with electronic unit.
In the active wheel side, whole motor is by the relative environmental sealing of Sealing.Which kind of degree is this class on the parts that rotate be sealed to is just calculated enough at least also disputable.
The housing designs of pump is two-part, and has different ladders and the through hole that is used to electrically contact.Develop different motors and shell according to the highest desirable quantity delivered.Because guide vane is shorter, can't realize there be not flowing of vortex fully probably.In addition, the pressure loss that causes because of the through hole that is used to electrically contact is also quite high, and therefore, the gain of the power consumpiton of motor is partly weakened owing to the pressure loss that occurs relatively.
FR2.222.885 discloses a kind of semiaxis streaming pump, and it has the shell of a multi-section section, and its intermediate section centers on motor, and is used as the motor and the pump casing of one, and wherein, described pump casing is connected by ribs with motor housing.Electric contact piece outwards guides by extra pipeline in these housing parts back on flow direction.
DE20201183U1 discloses a kind of axial-flow pump, and it has the motor and the pump casing part of this one equally.But outside electric contact piece is not disclosed.
In these two kinds of pumps, ribs all is designed to straight, therefore not as the guide vane wheel that reduces vortex, but produces the high pressure loss on the contrary, because the energy of the tangential component that flows almost completely is converted into frictional loss.
Therefore, technical problem to be solved by this invention is also also to reduce the size of motor thereby reduce pump when transmission power is identical, and avoid the pressure loss, that is improve the efficient of pump.Should reduce the weight and the number of components of pump in addition.
This technical problem solves thus, that is, described ribs is designed in this wise, that is, make it be used as the guide vane wheel of fluid pump and have such width, makes electric contacts to guide to staor winding by a hole one or more ribs from electronic unit.Therefore, ribs is born the additional functionality that tangential components of flow is not had more to be converted into to high pressure loss axial flow component.Efficient is enhanced, and part count reduces.The electric contact piece that passes rib has reduced flow resistance, and has improved the efficient of pump, because cancelled the structure of mobile inboard.Compare with known form of implementation, can make the wall thickness of pump casing less, because obtained enough intensity by ribs.Therefore, the number of parts and weight are reduced.
In a kind of form of implementation that further develops, the pump casing partial design that is positioned at radially outer is cylindric, can set up the pump casing part of suction side and pump casing on the pressure side being connected partly thus simply, and little loss occur.
In a special form of implementation, the pump casing of the suction side of expanding on flow direction part is constructed integratedly with a housing parts that is connected on the valve of upstream.Therefore, can realize that one has the bypass valve that is connected on the upstream or the modular organization of thermostat valve, reduce parts thus once more, and saved cost.
First motor housing part is preferably decided motor at the suction lateral confinement.Make, for example still can carry out at an easy rate by aluminium pressure pouring, wherein, this makes part count reduce again, and the receptance that is corroded is little and avoided loading error.
Therefore created a kind of motor, it has few part count, and little weight is easy to assembling, has reduced flow losses, and therefore known relatively pump has improved efficient.
A kind of form of implementation of the present invention is shown in the drawings, and is illustrated hereinafter.
Show a side view by fluid pump of the present invention with sectional view among the figure.
Fluid pump shown in the figure especially is suitable as the coolant pump in the internal-combustion engine, and it is driven by an electronically controlled motor 1, and described motor is made up of the rotor 4 that a stator 2 and is arranged on the live axle 3.Axial end portion at live axle 3 is provided with an active wheel 5, and this active wheel is designed to the semiaxis streaming, and substantially axially is delivered to pressure tap 7 by fluid pump by fluid, the especially cooling liquid that its rotation will be carried from suction adapter 6.
End on the pressure side at slit pipe 24 is provided with a blocking element 27, wherein is provided with second bearing 15 that is used for supporting driving shaft 3.This blocking element 27 axially fixing by motor housing part 9 on the pressure side, described motor housing part are arranged under there is the situation of a Sealing 28 centre in the receiving bore 29 of motor housing part 8 of suction side.
The motor housing part 9 that the contact of staor winding 18 is radially passed on the pressure side via a hole 30 is carried out.For the flow losses as is known in the art that prevent to be caused by this extra interior dress member, this hole is guided through ribs 31, and this ribs is for the enough intensity of pump casing and fixedly be necessary.For this reason, ribs 31 has enough width, and is configured to similar wing shape, therefore the contraction that can not produce cross section.Now, an electric contacts that does not illustrate can pass described hole 30 and be directed to an electronic unit that does not illustrate equally, and this electronic unit is used to control motor 1.
Shown in form of implementation in, ribs 31 moulding in this wise, that is, therefore this ribs does not directly need extra guide vane wheel in active wheel 5 back simultaneously as guide vane wheel.This makes the motor housing 8 of suction side and ribs and the cylindric pump casing part 32 that is positioned at radially outer to make integratedly simply.This pump casing part 32 is surrounded motor housing part 8 and the whole motor 1 that is positioned at inner radial.
Have in the centre respectively under the situation of a Sealing 50 at the downstream side of housing parts 8,31,32 and upstream side and to be fixed with two identical pump casing parts 33,34 by means of being threaded.The pump casing part 33 of the suction side of expanding on flow direction comprises that the suction adapter 6 and that is designed to cylindrical portion section 35 connects portion's section 36, expansion thereon.Be provided with the semiaxis streaming active wheel 5 of fluid pump in the transition region 37 between first section 35 and second section 36.In this form of implementation, on portion's section 36 of expansion, be connected with design shortlyer, cylindrical portion section 38 that diameter is bigger so that realize seamlessly transitting to cylindric pump casing part 32.
Correspondingly, from flow direction, pump casing part 34 on the pressure side also has the portion's section and the cylindrical portion section of contraction, wherein, and owing to the conformity of each several part is used identical reference character.
In addition, design has groove 39 on identical pump casing part 33,34, and the longitudinal end 40 of returning guide vane 41 embeds in the described groove.This time guide vane 41 usefulness are flow guide device 42 for export, can realize not having fully flowing of eddy current in pressure tap 7 back by means of this device.This outlet flow guide device 42 is configured on the surface 43 of motor housing part 9 on the pressure side, and be necessary thus, because the ribs 31 as guide vane wheel designs quite shortly, and in these zones of fluid pump, can not realize there be not flowing of vortex fully usually.In addition, motor housing part 9 on the pressure side can be made of plastic, and the motor housing part of suction side then is formed from aluminium as far as possible, thereby more expensive.The enforcement of the guide vane wheel in this zone needs a kind of relatively costly manufacture method, and the manufacturing of the outlet flow guide device on the plastic casing part 9 is simple and cheap.
Determined the position of the motor housing part 9 of pump casing part 34 relative pressure sides on the pressure side simultaneously by groove 39.When pump is assembled, when being used for the bolt that on the pressure side pump casing part 34 is fixed on cylindric pump casing part 32 is tightened, motor housing part 34 on the pressure side compresses motor housing part 9 relative motor housing parts 8 or be pressed in the receiving bore 29 of motor housing part 8 by returning guide vane 40.In addition, motor housing part 9 whereby relatively blocking element 27 or slit manage 24 compactedly, therefore do not need two motor housing parts 8,9 are done extra fixing.
When pump operation, the fluid of carrying, especially cooling liquid is transferred by pump casing 32 by the rotation of the active wheel of being made up of several runner vanes 44 5,33, space between 34 and motor housing 8 and 9, the ribs 31 of flowing through, at this, part vortex is owing to the function of ribs as guide vane is eliminated, and further by outlet flow guide device 42, the vortex that exists when flowing in this outlet flow guide device is eliminated fully, therefore, thereby the energy that expends can as far as possible fully be converted into pressure and can and be converted into axial flow, and can not cause big frictional loss.
In active wheel 5 back, a part of fluid flow through orifice 45, this hole design is on the motor housing part 8 of suction side.Another part fluid also flow to live axle 3 in active wheel 5 back, and flows through between clutch shaft bearing 11 and the live axle 3 at this, thereby it is sufficiently lubricated to make that the sliding bearing that exists obtains.Therefore, the cold fluid in rotor chamber is carried between the live axle 3 and second bearing 15 again and is transported to a space 46 that is positioned at thereafter by the sightless hole in the blocking element 27.This space 46 is by another hole 47 and the spatial communication that is positioned at thereafter, and described hole 47 axially extends through motor housing part 9 on the pressure side.Therefore, both form the lubricated of bearing 11,15 and also may cool off and discharge the air quantity that may exist in the rotor chamber.
This semiaxis streaming pump is characterised in that it can construct very for a short time, because this pump can obtain identical transmission power by the rotating speed of comparing littler motor size and Geng Gao with known pump when power consumpiton is identical.This especially realizes by the extreme pressure loss that reduces in this design, but also can realize by semiaxis streaming structure.
In addition, the manufacturing of this type of pump can be very cheap, because the parts of different designs become still less.The mistake that this may occur when having reduced assembling simultaneously.Save extra guide vane wheel and on ribs integrated electric contact piece can avoid using extra part and reduce the pressure loss.Thereby reach higher efficient on the whole.
Based on the simplicity of pump casing part 33,34, also can be equipped with the flange that is arranged in pressure tap or the suction adapter naturally for them.Both can directly on motor housing, connect thus, also can be the fluid volume flow of improve carrying a plurality of pumps of connecting.This realizes promptly, not having flowing of vortex by 42 generations of outlet flow guide device especially thus, and the pump runner 5 that therefore is connected on the downstream can directly be met stream, and does not have energy loss.Therefore when requiring double power, also needn't construct a pump that has bigger motor, but because parts are identical, the pump with the respective number of needs connects successively simply.
Owing to especially aspirate the simplicity of the pump casing part 33 of side, can consider also that with this pump casing part and valve shell part structure integratedly therefore, pump casing part 33 for example has a female part that is used for a bypass or an integrated thermostat valve.The part shell of one ring-type guiding valve also can be made integratedly with the pump casing part 33 of suction side.
It is to be noted, only relate to a kind of form of implementation of the present invention in the embodiment shown in the figures, under the situation of the protection domain that does not depart from claim, can change its structure in all fields.
