Abstract

The utility model relates a lubricating structure for a transaxle differential. The lubricating structure comprises oil grooves, an oil collecting cavity, an oil inlet, an oil holding plate and an oil collecting chamber. The oil grooves are respectively reserved on the inner surface of a differential housing and the inner surface of the differential bearing cup in a main reducer shell, the oil collecting cavity and the oil inlet are arranged on an adjusting nut assembly, the oil holding plate and the oil collecting chamber are arranged in a back cover of the transaxle, and lubricating oil penetrates through an oil path composed by the oil holding plate, the oil collecting chamber, the oil grooves ,the oil inlet and the oil collecting cavity in sequence and enters the inside of the differential housing. By means of the lubricating structure with no holes on the differential housing, the phenomenon of lubricating oil hurling out from the differential through holes is avoided, and accordingly inadequate lubrication of the parts of the differential in the high speed is avoided. Conversely, in the case of avoiding oil leaking, the lubricating structure is capable of transporting the lubricating oil driven by the rotation of a passive bevel gear into the differential, so that different structures inside the differential can be well lubricated.
