Abstract
The present invention provides a dry, dual clutch module having reduced axial length. The clutch module includes a larger diameter, single plate outer clutch which drives a first transmission input shaft or drive quill and a smaller diameter, double plate inner clutch which drives a second transmission input shaft or drive quill. The smaller diameter clutch is nested within the larger diameter clutch and thus they essentially reside within the same axial space.
Claims20
A dual clutch assembly for a motor vehicle transmission comprising, in combination,
- a first clutch having a first input member, a first clutch plate coupled to a first output member and a first clutch operator, and
- a second clutch having a second input member, a pair of clutch plates coupled to a second output member and a second clutch operator,
- said first clutch plate having an inside diameter larger than an outside diameter of said pair of clutch plates, whereby said second clutch is nested in said first clutch.
A dual clutch module for motor vehicle power trains comprising, in combination,
- a first, outer clutch assembly including a first pair of spaced-apart drive plates, a first driven plate disposed between said first pair of drive plates, a first clutch operator and a first apply plate operably disposed between said first operator and one of said pair of spaced-apart drive plates, and
- a second, inner clutch assembly including a plurality of spaced-apart drive plates, at least a pair of driven plates interleaved with said plurality of drive plates, a second clutch operator and a second apply plate operably disposed between said second operator and one of said plurality of drive plates,
- whereby said second, inner clutch is nested within said first, outer clutch.
A dual clutch module for a motor vehicle transmission comprising, in combination,
- an outer clutch assembly including a pair of spaced-apart outer drive plates, an outer driven plate disposed between said pair of outer drive plates, an outer clutch operator and an outer apply plate operably disposed between said outer operator and one of said pair of spaced-apart outer drive plates, and
- an inner clutch assembly including a plurality of spaced-apart inner drive plates, at least a pair of inner driven plates interleaved with said plurality of outer drive plates, an inner clutch operator and an inner apply plate operably disposed between said inner operator and one of said plurality of inner drive plates,
- whereby said inner clutch is nested within said outer clutch.
