STRUCTURE FOR LUBRICATING TRANSMISSION

摘要

An oil-feeding member (100) catches oil picked up by a gear, and is provided with a gutter (132) guiding the oil from one side to the other of a transmission in an axial direction. The gutter (132) has a bottom which is divided into a first bottom portion (141) and a second bottom portion (142). The second bottom portion (142) is provided with an oil-dripping hole (142a, 142b). The first and second bottom portions (141, 142) are configured so that (i) the oil flows over only the first bottom portion (141) toward the other side if an amount of the oil caught by the oil-feeding member (100) is smaller than or equal to a predetermined amount, and that (ii) the oil flows over both of these bottom portions (141, 142) toward the other side if the amount of the oil is greater than the predetermined amount.

主权项

1. A structure for lubricating a transmission to be provided for a vehicle, the structure comprising
an oil-feeding member arranged in a transmission case and configured to catch oil picked up by a gear, wherein the oil-feeding member includes a gutter with an oil-dripping hole that is cut through a bottom of the gutter, the gutter guiding the oil that has been caught from one side to the other of the transmission in an axial direction to feed the oil to a part-to-be-lubricated which is provided in the transmission case and positioned on the other side, the oil-dripping hole allowing the oil to drip to an intermediately placed part-to-be-lubricated which is also provided in the transmission case and positioned at an intermediate position in the axial direction, the bottom of the gutter is divided into a first bottom portion and a second bottom portion, the second bottom portion being provided with the oil-dripping hole being cut through the second bottom portion, and the first and second bottom portions are configured so that (i) the oil flows over only the first bottom portion toward the other side if an amount of the oil caught by the oil-feeding member is smaller than or equal to a predetermined amount, and that (ii) the oil flows over both of the first and second bottom portions toward the other side if the amount of the oil caught by the oil-feeding member is greater than the predetermined amount.
