Abstract
The utility model provides a coaxial output coupling box with oil deflector rings for pure-electrical drive and combination drive, which is installed in pure-electrical drive and combination drive automobiles. The interior of the coupling box also comprises two oil deflector rings and one hollow shaft, wherein the two oil deflector rings are respectively sheathed on the outer sides of both ends of the cambered surface of the hollow shaft in an enclosing manner and axially connected through a bearing in a press manner. The structure of the coaxial output coupling box with the oil deflector rings for pure-electrical drive and combination drive can effectively prevent a great amount of lubricating oil of the bearing and a gear wheel from flowing into a chamber of a drive motor, thereby achieving the function and effectively avoiding the assembly of a high-speed oil seal herein. Due to the non-contact of the coaxial output coupling box with the oil deflector rings for pure-electrical drive and combination drive, the coaxial output coupling box does not need to be maintained and replaced in the entire service life thereof, thereby being convenient for use and reducing the cost.
