Embodiment Construction

[0027] The following description is merely exemplary in nature and not intended to limit the disclosure and its application or uses. It should be understood that throughout the drawings, corresponding reference numerals indicate like or corresponding parts and features.

[0028] Figures 1 to 6 and 9 illustrate a one-way overrunning clutch 10 sealed for life. The one-way overrunning clutch 10 is configured to selectively transfer torque between rotatable components within a vehicle (not shown). Clutch 10 may be disposed within, adjacent to, or within any number of powertrain components such as the engine, transmission, transfer case, propshaft, primary axle, rear axle, differential, electric motor, etc. Spaced out.

[0029] The clutch 10 includes an outer race 46 adapted to be fixed for rotation with a first rotatable member (not shown), an inner race 48 adapted to be fixed for rotation with a second rotatable member (not shown), multiple a roller 50, a cage 52, a pluralit...

Abstract

A one-way clutch assembly includes an inner race adapted to be fixed for rotation with a first rotatable member, an outer race having circumferentially spaced apart cam surfaces and being adapted to be fixed for rotation with a second rotatable member as well as a plurality of roller elements positioned therebetween. A plurality of circumferentially extending springs cooperate with the cage to align each roller element with the cam surfaces. The springs and cage urge the roller elements away from the inner race. A retaining mechanism captures lubricant in contact with the roller elements.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Provisional Application No. 61 / 096,935, filed September 15, 2008. The entire disclosure content of the aforementioned application is incorporated herein by reference. technical field [0003] The present disclosure generally relates to an overrunning roller clutch for selectively transferring torque between two rotatable members. More specifically, a sealed-for-life dry one-way clutch is disclosed. Background technique [0004] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art. [0005] At least one known clutch associated with automobiles is arranged in close proximity or partly within the engine block of an internal combustion engine. This positioning is required because the lubricant in the engine block is also supplied to the clutch. While this configuration may prove advantageous, the...
