The molding together of the shell of axle, thus reduce the quantity of parts and shorten the manufacturing time of assembling.Fig. 3 shows
Go out the signal schematic diagram of this lubricating oil pump module in internal combustion engine.Additionally, Fig. 4 show cutting by
The drawing in side sectional elevation of the lubricating oil pump of prior art, the rotor of lubricating oil pump is torsionally fixed on two angular momentum balances
On in axle one.
Fig. 3 shows the key diagram of known lubricating oil pump module 2, and wherein, four cylinder engine is with gas
Cylinder 31,32,33 and 34, can only see the connecting rod of cylinder in key diagram, and it passes through sliding bearing
16 act on jointly with bent axle 6, and the electromotor marked with the dotted line of three points here as square frame
Jointly act in cabin 17.
Outside enging cabin 17, bent axle 6 has the gear ring 28 of chain-drive mechanism 13, chain-drive mechanism
13 by driving-chain gear 12 drive bent axle 6 following with the first of two balance weights 23 and 24
Angular momentum balance axle 29.This first angular momentum balance axle 29 is disposed with the commutating tooth that gear ratio is 1: 1
Wheel speed change gear 11, it drives the second angular momentum balance axle 35, is disposed with thereon in oil sump 4
The rotor 9 of lubricating oil pump 7, wherein, the pump orifice 14 of lubricating oil pump 7 immerses in oil sump.
Because angular momentum balance axle 29 rotates with the rotating speed identical with bent axle 6 with 35, and rotor 9 resists
It is fixed on angular momentum balance axle 35, so lubricating oil pump 7 is with the rotation speed operation identical with bent axle 6 with turning round.
Additionally, Fig. 4 shows the cutting drawing in side sectional elevation by a part for the lubricating oil pump module 2 of prior art,
Lubricating oil pump 7 and its rotor 9 it is disposed with in this lubricating oil pump module.Here, rotor 9 is fixed thereon
Also it is disposed with on the second angular momentum balance axle 35 of balance weight 23 and 24.Angular momentum balance axle 35 supports
On sliding bearing 36 and 37, wherein, sliding bearing 36 is arranged in the rotor 9 and just of lubricating oil pump 7
Between the spur gear 38 of speed change gear 11, and the second sliding bearing 37 arranges fore
Between one balance weight 23 and second balance weight 24 at rear portion.
This known lubricating oil pump module 2 and its lubricating oil pump module housing 3 are arranged so as to angle [alpha]
Under bent axle so that the pump orifice 14 of lubricating oil pump 7 is positioned at oil sump 15 and balance weight 23 and 24 exists
Rotate on highly 39.Although lubricating oil pump shell 40 Flange joint is at the second angular momentum balance in the diagram
On the shell 41 of axle 35, the prior art in beginning file is open, and shell 40 and 41 can be shaped to
Lubricating oil pump module housing 3.However the shortcoming still suffered from is, the rotating speed of lubricating oil pump 7 rotor 9 is unfavorable
Ground is affected by the rotating speed of angular momentum balance axle 35.
Summary of the invention
The technical problem to be solved is, overcomes shortcoming of the prior art and creates one
Lubricating oil pump module, wherein the rotating speed of rotor of engine oil pump is not in contact with the rotating speed of angular momentum balance axle.
This technical problem is solved by a kind of lubricating oil pump module with lubricating oil pump module housing, wherein this machine
Fuel pump module is arranged in below bent axle in the oil sump of internal combustion engine.In described lubricating oil pump module housing
It is disposed with the parts of all motions of lubricating oil pump and angular momentum balance axle.The rotor of lubricating oil pump is arranged in described
In lubricating oil pump module housing with on the described separate armature spindle of angular momentum balance axle.Armature spindle is by described
It is connected spur gear speed change gear in lubricating oil pump module housing and described angular momentum balance shaft mechanical.
Owing to armature spindle is unrelated with angular momentum balance axle or separates, the rotor of lubricating oil pump can be made to have optimization
Rotating speed.This rotating speed can be higher or lower than the rotating speed of bent axle.The vane pump of regulation volume flow can be used
Make lubricating oil pump, wherein it is possible to regulated by corresponding hydraulic feedback according to the oil pressure in electromotor main oil gallery
Eccentricity between blade enclosure and armature spindle.Can be in lubricating oil pump module housing by electromechanical control fuel tap
Another conditioning chamber of interior connection, thus can reduce volume flow and reduce oil pressure.Institute is promising needed for this
Movable parts be integrated in the lubricating oil pump module housing of lubricating oil pump module.
The another kind of form of implementation of the present invention specifies, cloth on the external armature spindle of lubricating oil pump module housing
Putting a driving-chain gear, it is mechanically connected with bent axle by chain-drive mechanism.Therefore, with favourable
Mode directly provides one to turn needed for angular momentum balance axle by the speed change of chain-drive mechanism for armature spindle
The rotor speed of the optimization that speed is unrelated.In addition specifying, the pump orifice of the lubricating oil pump of lubricating oil pump module immerses oil
In the oil sump of drain pan.
As mentioned above, in lubricating oil pump module housing, one is arranged with main regulation room and additive regulating
The two-stage lubricating oil pump of room.Except sliding bearing and other parts of electromotor, in lubricating oil pump module housing
Sliding bearing and/or rolling bearing are also supplied by this two-stage lubricating oil pump.Lubricating oil pump module has drive shaft, passes
Dynamic sprocket is torsionally arranged in this drive shaft outside lubricating oil pump module housing.Drive shaft is at lubricating oil pump mould
There is between two bearings in block shell a spur gear speed change gear being transferred to angular momentum balance axle
Driving gear.So design spur gear speed change gear driving gear so that its be arranged in angular momentum
Driven gear on balance axle ensure that gear ratio or speed reducing ratio together, and this gear ratio or speed reducing ratio are at triplex
Angular momentum balance axle is made to rotate with the rotating speed identical with bent axle in the case of electromotor, or at four cylinder engine
In the case of make angular momentum balance axle with double speed of crankshaft rotating speed rotate.
Here, two balance weights being arranged on angular momentum balance axle between two bearings for compensate with
The torque momentum of the internal combustion engine of piston unbalanced.To this end, angular momentum balance axle is as with driven gear
Driven shaft relatively with drive gear armature spindle be arranged in lubricating oil pump module housing.So angular momentum
The driven gear of balance axle is nibbled in described lubricating oil pump module housing with the driving gear of rotor of engine oil pump axle
Close rather than be contrary as prior art.
Additionally, the gear ratio of such design arrangement spur gear speed change gear in lubricating oil pump module housing,
Make the situation at the gear ratio in view of the chain-drive mechanism being arranged in outside described lubricating oil pump module housing
Under, the rotating speed of the angular momentum balance axle rotating speed equal to bent axle or the twice equal to speed of crankshaft.
Thus, a kind of probability is created by this lubricating oil pump module, i.e. turning rotor of engine oil pump
Speed becomes different from the Design of Rotation of the bent axle of joint angle momentum balance axle so that the gear ratio of chain-drive mechanism
Or speed reducing ratio defines the rotor speed of described rotor of engine oil pump.
In the another kind of form of implementation of the present invention, for three-cylinder engine, turning of rotor of engine oil pump
Speed is less than the rotating speed of the bent axle of described three-cylinder engine.Therefore, this lubricating oil pump module is preferably used in tool
Have in the vehicle of the internal combustion engine with three cylinders.
