Title:
DIFFERENTIAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/184428
Kind Code:
A1
Abstract:
Regarding a differential device in which a pinion shaft in a regular mounting position overlaps with a ring gear fixed to a differential case when viewed in a projection plane orthogonal to the pinion shaft, a differential case (8) is provided with a shaft insertion hole (81) constituting one pinion shaft support portion (H1), and the shaft insertion hole has an insertion allowance hole portion (81a) into which a pinion shaft (21) is inserted from the outside of the differential case without interfering with a ring gear (9), and a rotation allowance hole portion (81b) that allows the pinion shaft to rotate toward a regular mounting position. An inner surface (8i) of the differential case is formed in a shape that does not hinder the rotation of a side gear (23) and a pinion gear (22) within the differential case when the pinion shaft rotates to the regular mounting position. This allows the pinion shaft to be easily assembled in the regular mounting position without interfering with the ring gear, and the pinion gear and the side gear can be set in a pre-geared state in the differential case before the pinion shaft is assembled to enhance the assembly workability.
