Title:
TRANSMISSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/201539
Kind Code:
A1
Abstract:
In this transmission device, a differential case of a differential accommodated inside a transmission case has a trunk part that can store oil, an oil inlet that opens to one axial side of the differential case, and an oil outlet that opens to the other axial side of the differential case. The differential case (20) is provided with at least part of a contaminant pocket (70) that has an inlet (70i) facing the interior of the trunk part (20a) of the differential case (20) and that can trap contaminants in the oil inside the trunk part (20a). The inlet (70i) is disposed, among the inner surface of the differential case (20), in a maximum inner diameter part (20d) where the centrifugal force during rotation of the differential case (20) most strongly acts, or more toward the oil outlet (20o) in the axial direction than the maximum inner diameter part (20d). Thus, the diffusion of contaminants inside the trunk part is suppressed and reduced differential performance caused by the diffusion of contaminants is also suppressed.
