Title:
DRIVE TRANSMISSION DEVICE FOR VEHICLE
Document Type and Number:
WIPO Patent Application WO/2023/190129
Kind Code:
A1
Abstract:
A drive transmission device (10) comprises: a speed-reduction planetary gear mechanism (20) for reducing the speed of rotation of an input shaft (15) and transmitting the speed-reduced rotation to an output shaft (16); and a case (50) that stores the planetary gear mechanism (20). A scraping-up part (35) for scraping-up oil in the case (50) is provided to the outer peripheral part of a carrier (30) of the planetary gear mechanism (20). The scraping-up part (35) is disposed on one side in an axial direction (X) with respect to a ring gear (25). The lower end (Tf) of the scraping-up part (35) in a rotation trajectory is disposed on a lower side (Z2) lower than the lower end (Tp) of a pinion (22) in the rotation trajectory. An oil supply path (Rt) through which the oil scraped-up by the scraping-up part (35) flows to a lubrication necessary part (70) is formed in the case (50).
