Abstract

PURPOSE:To aim at improvements in a rate of fuel consumption, by installing a through hole, leading drain oil of a valve body into the side of a one-way clutch, in a transmission case, while making pump capacity smaller so as to cause the drain oil to lubricate the clutch. CONSTITUTION:A through hole 13, reaching to the side of an outer race 6, is installed in a part 12 of a transmission case 2 which positions the outer race 6 of a one-way clutch 5 in the axial direction and houses it unturnably. A part of the drain oil discharged out of various valves inside a valve body 3 flows down to the transmission case part 12 and is led into the side of the outer race 6 by way of the through hole 13. This drain oil penetrates into space between the outer race 6 and an inner race 10 and positively lubricates one-way clutch elements inside these races.

(2) The prior art automatic transmission uses a one-way clutch as an essential groove component as a reaction force brake that makes the elements of the planetary gear arrangement non-reversible when the gear stage (usually first gear) is selected. . By the way, in order to lubricate this one-way clutch, conventionally, as shown in Japanese Unexamined Patent Publication No. 68-5567, a part of the pumped fluid discharged from the oil pump of the transmission control hydraulic system is guided to the one-way clutch for lubrication. It was common.

However, with this one-way clutch lubrication system, the oil pump must pump the amount of oil S required for the shift control hydraulic system plus the amount of one-way clutch lubricating oil, which increases the customer use of the oil pump. In addition, the one-way clutch lubricating oil passage becomes extremely complicated and requires separate oil passage machining and parts, which is disadvantageous in terms of cost.

(8) Purpose of the Invention The present invention provides that, in the case of an automatic transmission such as an automatic transmission used for a front wheel drive vehicle, in which the valve body for speed change control is placed above the transmission case due to installation space, the valve body is ejected. From the viewpoint that the drain t1 ■ is simply returned to the oil pan at the bottom of the transmission case, this drain curve is used to lubricate the one-way clutch and then returned to the oil pan.
The purpose is to solve the five problems mentioned above.

The one-way clutch 5 is provided in the transmission case 2 with its outer race 6 positioned in the axial direction by a snap ring 7 as shown in FIG.
As shown in FIG. 49 to prevent rotation. The inner race 10 of the one-way clutch 5 is rotatable relative to the outer race 6 and therefore the transmission case 2 only in the direction of arrow α in FIG. 2, and cannot be rotated in the opposite direction. As a result, the one-way clutch 5 performs a predetermined one-way rotational clutch function, and is put into practical use by connecting the inner race 0 to the corresponding planetary gear carrier 11.

In the present invention, a through hole 18 extending from the outer circumferential surface to the side surface of the outer race 6 is provided in the portion [2] of the transmission case 2 in which the outer race 6 of the one-way clutch 6 is axially positioned as described above and housed in a non-rotatable manner. This constitutes a lubricating device for the one-way clutch 5. Note that, as shown in FIG. 2, the through hole L8 is preferably placed slightly (about 70 degrees) on the advancing side of the inner race rotation direction (α) from the medical plane that intersects the rotation axis of the inner race 10.

(6) Effects of the Invention Thus, the device of the present invention, for example as described above, guides the drain oil discharged from the valve body 8 to the side surface of the one-way clutch 5 through the through hole [8] of the transmission case 2, and Since internal lubrication is performed, the oil pump does not need to discharge the oil for lubrication, and the pump capacity can be reduced accordingly, reducing the pump driving load on the engine and improving fuel efficiency. In addition, a one-way clutch lubricating oil passage is made from the same egg white through the through hole L provided in the transmission case 2.
8, making the oil passage extremely easy to process.
