<P>PROBLEM TO BE SOLVED: To provide an electric vehicle deceleration differential device consisting of a planetary gear deceleration machine and a differential device, which is reduced in size and weight by adoption of an oil bathing lubrication as a lubricating means and thereby extends a mileage per charge, and, at the same time, to solve the problem wherein scraping of lubricating oil becomes insufficient because the lubricating oil is moved in a rotating direction. <P>SOLUTION: The electric vehicle deceleration differential device is composed of assemblage of the planetary gear deceleration machine 12, the differential device 13, and the lubricating means 14. The device adopts an oil bathing lubricating means as the lubricating means 14, and is equipped with a lubricating oil controlling means consisting of a plurality of protrusions 109, on both sides of the lowermost end point of a deceleration differential casing. The movement of the lubricating oil is controlled thereby. <P>COPYRIGHT: (C)2012,JPO&INPIT |
