Title:
DIFFERENTIAL APPARATUS
Document Type and Number:
WIPO Patent Application WO/2016/158059
Kind Code:
A1
Abstract:
In the present invention, a differential case (54): has formed therein two oil holes (59) in addition to a pinion shaft hole (57) and a pair of drive shaft holes (58a, 58b); and has attached thereto an annular receiver (70) that has an inner radius smaller than the outer radius of a side gear washer (56) with respect to the rotation center of a rotation axis of a drive shaft 28, and has an outer radius greater than the distance between the rotation center of the rotation axis of the drive shaft (28) and the outermost edge of the oil hole (59). This enables regulation of discharge of a lubricating oil at the outer radius side rather than the inner radius side of the receiver (70), and allows the lubricating oil to be supplied to the side gear washer (56) both when the differential case (54) is rotating and when the differential case (54) is not rotating.
