It is rotatablely connected with the front end of pump body.
As further improvement of the utility model, the rear end portion of the pump body is equipped with pump cover.
As further improvement of the utility model, the Oil pump internal rotor is connected with transmission input shaft spline.So
It sets, is easy to implement Oil pump internal rotor and the close of transmission input shaft is stably connected with.
As further improvement of the utility model, the clutch is connected with transmission input shaft spline.So set,
It is easy to implement clutch and the close of transmission input shaft is stably connected with.
As further improvement of the utility model, the outer surface of the Oil pump internal rotor and the inner surface of oil pump outer rotor
Equipped with intermeshing engaging tooth, the region formed between two groups of engaging tooths is oil duct.So set, realize Oil pump internal rotor
Couple with the engaged transmission of oil pump outer rotor, while make to form oil circuit between Oil pump internal rotor and oil pump outer rotor.
As further improvement of the utility model, the tooth form of the engaging tooth is cycloidal tooth profile.
The beneficial effects of the utility model are：
1st, the transmission oil pump of the utility model forms internally meshed rotor by Oil pump internal rotor and oil pump outer rotor and pumps, and makes
The utility model has the advantages of engagement registration is big, stable drive, 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 pressure oil；
3rd, the utility model directly drives Oil pump internal rotor rotation by transmission input shaft, compared to traditional type of drive,
Make transmission 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 utility model, oil
The front end and the rear end of clutch for pumping the pump housing are connected by bearing, so as to play the role of support, fixed to clutch；
In general, the utility model makes the structure more simple and compact of transmission oil pump, under smaller volume, meets
Clutch, brake etc. possess transmission oil pump and provide branch for clutch to pressure, lubrication and the demand of cooling in speed changer
Support and the ability of positioning make the type of drive of transmission oil pump be changed to transmission input shaft driving by fluid torque-converter driving, subtract
Few mechanical loss of the torque in transmittance process caused by fluid torque-converter, makes entire gearbox designs become simple, space cloth
It puts more rationally.
Description of the drawings：
Fig. 1 is the structure diagram of the utility model；
Fig. 2 is the schematic diagram that Oil pump internal rotor and oil pump outer rotor are meshed；
Fig. 3 is the three-dimensional effect diagram of the utility model.
Specific embodiment：
With reference to Fig. 1 and Fig. 3, the oil pump for automatic transmission of automobile of the utility model is defeated including pump body 9, speed changer
Enter axis 7, oil pump outer rotor 11, Oil pump internal rotor 12 and clutch 8, the oil pump outer rotor 11 and Oil pump internal rotor 12 are in oil
It pumps in the pump housing 9, oil pump outer rotor 11 and 12 eccentric setting of Oil pump internal rotor, Oil pump internal rotor 12 is same to be located in transmission input shaft
On 7, the clutch 8 be arranged on transmission input shaft 7 on and in pump body 9 front, the back end outer surface of clutch 8 with
