Lubricating device for components within casing structure of vehicular power transmitting system
A lubricating device for lubricating components includes first and second lubricant guide plates which have respective inclination angles with respect to a horizontal line such that the angle of inclination of the first lubricant guide plate is smaller than that of the second lubricant guide plate. The inclination angle of the first lubricant guide plate is determined to permit the lubricant oil guided by the first lubricant guide plate to be directed into the catcher reservoir, and to inhibit the lubricant oil from being supplied to component or components disposed above the gear, and the inclination angle of the second lubricant guide plate is determined to permit the lubricant oil guided by the second lubricant guide plate to be supplied to the component or components disposed above the gear.
1. A lubricating device for lubricating components within a casing structure of a vehicular power transmitting system, the lubricating device comprising:
a gear immersed in a lubricant oil within the casing structure;
a catcher reservoir formed within the casing structure, for storing the lubricant oil splashed up by said gear; and
a first lubricant guide plate and a second lubricant guide plate which are disposed above said gear, for guiding the lubricant oil splashed up by said gear, to the catcher reservoir, wherein
the first and second lubricant guide plates are formed such that the first and second lubricant guide plates do not overlap each other in an axial direction of said gear,
the first and second lubricant guide plates having respective inclination angles with respect to a horizontal line such that an inclination angle of the first lubricant guide plate is smaller than that of the second lubricant guide plate,
the inclination angle of the first lubricant guide plate being determined to permit the lubricant oil guided by the first lubricant guide plate to be directed into the catcher reservoir, and to inhibit the lubricant oil from being supplied to at least one of the components which is disposed above said gear, and
the inclination angle of the second lubricant guide plate being determined to permit the lubricant oil guided by the second lubricant guide plate to be supplied to the at least one of the components which is disposed above said gear.
2. The lubricating device according to claim 1 , wherein the casing structure includes a first casing member and a second casing member which are fixed together, and the first lubricant guide plate is formed within the first casing member while the second lubricant guide plate is formed within the second casing member.
3. The lubricating device according to claim 2 , wherein the first lubricant guide plate is an integral part of the first casing member which is a cast body, and the second lubricant guide plate is an integral part of the second casing member which is a cast body.
4. The lubricating device according to claim 3 , wherein said gear is a helical gear having a helix angle determined such that the lubricant oil splashed up by the helical gear is scattered in a direction toward the first lubricant guide plate.
5. The lubricating device according to claim 2 , wherein said gear is a helical gear having a helix angle determined such that the lubricant oil splashed up by the helical gear is scattered in a direction toward the first lubricant guide plate.
6. The lubricating device according to claim 1 , wherein said gear is a helical gear having a helix angle determined such that the lubricant oil splashed up by the helical gear is scattered in a direction toward the first lubricant guide plate.
