Title:
DIFFERENTIAL GEAR
Document Type and Number:
WIPO Patent Application WO/2020/184707
Kind Code:
A1
Abstract:
In this differential gear in which at least a portion of a pinion shaft overlaps a ring gear when viewed in a projection surface perpendicular to the pinion shaft at a regular attachment position, a differential case (8) has a shaft insertion hole (8bh) which is spaced apart from pinion shaft support parts (81, 82) and through which the pinion shaft (21) can pass, the shaft insertion hole is present at a position where the pinion shaft is allowed to be inserted into a pinion gear (22) inside the differential case without interfering with the ring gear (9) up to a predetermined insertion end position (21E) from the outside of the differential case, and the inner surface of the differential case has a shaft movement groove (41) that can receive both end sections of the pinion shaft inserted up to the insertion end position (21E), and allows both the end sections to move from the receiving position to the pinion shaft support part. Accordingly, the limitation in the shape of the ring gear and the like can be reduced without a need to expand the hole of the differential case serving as the pinion shaft support part to avoid interference with the ring gear when assembling the pinion shaft.
