For AT, to realize more efficient energy-conservation, more gears are relatively effective measures.Meanwhile AT gearboxes collocation motor, realize mixed
It is also a main flow direction to close power.Motor vehicle driven by mixed power compares traditional power vehicle, natural for the performance requirement of speed changer
Difference, traditional AT oil pumps must be innovated, and could meet the performance requirement of mixed dynamic speed changer.
For automatic gearbox, want to realize self shifter, it is necessary to each executive component is worked in coordination, and it is oily
The meaning of pump is exactly to provide power to executive component.Mixed dynamic speed changer is eliminated fluid torque-converter, increased due to the presence of motor
Clutch, cause traditional oil pump can not meet the needs of mixed dynamic speed changer.
The content of the invention：
The invention provides a kind of oil pump for automatic transmission of automobile, and it is suitable for increasing the mixed dynamic speed changer of clutch
Demand.
The present invention oil pump for automatic transmission of automobile, to achieve the above object used technical scheme be：Including
Pump body, transmission input shaft, oil pump outer rotor, Oil pump internal rotor and clutch, the oil pump outer rotor and oil pump are interior to be turned
In pump body, oil pump outer rotor and Oil pump internal rotor eccentric setting, Oil pump internal rotor input son with speed changer is located in
On axle, the clutch is located on transmission input shaft and the front in pump body, back end outer surface and the oil of clutch
The front end rotation connection of the pump pump housing.
As a further improvement on the present invention, the rearward end of the pump body is provided with pump cover.
As a further improvement on the present invention, the Oil pump internal rotor is connected with transmission input shaft spline.It is arranged such,
It is easy to implement Oil pump internal rotor and the close of transmission input shaft is stably connected with.
As a further improvement on the present invention, the clutch is connected with transmission input shaft spline.It is arranged such, is easy to
Realize that clutch and the close of transmission input shaft are stably connected with.
As a further improvement on the present invention, the inner surface of the outer surface of the Oil pump internal rotor and oil pump outer rotor is provided with
Intermeshing engaging tooth, the region formed between two groups of engaging tooths is oil duct.It is arranged such, realizes Oil pump internal rotor and oil
The engaged transmission connection of pump outer rotor, while make to form oil circuit between Oil pump internal rotor and oil pump outer rotor.
As a further improvement on the present invention, the tooth form of the engaging tooth is cycloidal tooth profile.
The beneficial effects of the invention are as follows：
1st, transmission oil pump of the invention forms internally meshed rotor pump by Oil pump internal rotor and oil pump outer rotor, makes this hair
Bright have that engagement registration is big, stable drive, the advantages of oil suction condition is good；
2nd, the volume of the pressurization working lumen formed by Oil pump internal rotor, oil pump outer rotor with pump body, pump cover changes,
Realize oil suction, the function of force feed；
3rd, the present invention directly drives Oil pump internal rotor rotation by transmission input shaft, compared to traditional type of drive, makes biography
It is dynamic more steady, more efficient；
4th, the rear end of pump body is designed like tube-in-tube structure and is set in outside the front end of clutch by the present invention, oil pump pump
The front end of body and the rear end of clutch are connected by bearing, so as to play support, fixed effect to clutch；
In general, the present invention makes the structure more simple and compact of transmission oil pump, under less volume, meets speed change
Clutch, brake etc. be to pressure, lubrication and the demand of cooling in device, possess transmission oil pump for clutch provide support and
The ability of positioning, the type of drive of transmission oil pump is changed to transmission input shaft driving by fluid torque-converter driving, reduce because
Mechanical loss of the moment of torsion caused by fluid torque-converter in transmittance process, makes whole gearbox designs become simple, and space is arranged more
Rationally.
Brief description of the drawings：
