Further, the outer surface of the case of transmission is integrally formed with oil separator case.
Further, in addition to gs-oil separator lid, the oil separator case closing lid face and gs-oil separator lid
Oil-gas separation chamber is formed between closing lid face, the oil-gas separation chamber is used for supplied gas stream provided with what is connected with crankcase body inner chamber
The air admission hole entered and the venthole for being used for supplied gas outflow being in communication with the outside, are provided between the air admission hole and venthole and are used for
Make the labyrinth channel of Oil-gas Separation.
Further, the air admission hole is located on oil separator case, and the venthole is located on gs-oil separator lid.
The beneficial effects of the utility model：
Automobile engine crankcase assembly of the present utility model, crankcase body and case of transmission integrated setting, are carried
The high structural strength of case of transmission, is easy to process and assemble, reduces product cost；The structure of integral type is advantageous to improve hair
The globality of motivation, engine volume is effectively reduced, is adapted in use on compact-type automobile, and because power input shaft is installed
The axis in hole and the axis of power output shaft mounting hole are parallel with the axis in crankshaft installed hole, stability during transmission compared with
It is high.
Brief description of the drawings
The utility model is further described with reference to the accompanying drawings and examples：
Fig. 1 is the connection diagram of crankcase body and case of transmission；
Fig. 2 is the connection diagram of oil separator case and case of transmission；
