LUBRICATING STRUCTURE OF DIFFERENTIAL GEAR UNIT |
摘要 |
A lubricating structure of a differential gear unit includes a differential case that rotatably supports side gears and pinions; a differential housing that rotatably supports the differential case via a bearing; and a lubrication hole that leads lubricating oil from a first chamber space formed between the differential case and the differential housing to a second chamber space formed around one drive shaft. A third chamber space is formed inside the differential case. A smallest passage sectional area of a lubricating oil flow path that leads from the second chamber space to the first chamber space via the bearing is smaller than a smallest passage sectional area of the lubrication hole, and a smallest passage sectional area between the second chamber space and the third chamber space and a smallest passage sectional area in the third chamber space are larger than the smallest passage sectional area of the lubrication hole. |
