Abstract
A housing for a multiple-disc clutch includes a toothed ring having a plurality of disc-driving teeth arranged on an inner circumferential surface of the same so as to be distributed in the circumferential direction and extending in a ring longitudinal direction. A flywheel is connected to a first end of the toothed ring for common rotation and a cover is connected to a second end the toothed ring for common rotation. At least one component of the cover and flywheel is connected to the toothed ring by a fastening arrangement that does not include fastening bolts.
Claims15
A housing for a multiple-disc clutch of a motor vehicle comprising:
- a tooth ring (16;
- 16a) having a first end, a second end, an inner circumferential surface (22) and a plurality of disc-driving teeth (24;
- 24a, 24b) arranged on said inner circumferential surface (22) so as to be distributed in a circumferential direction and extending in a ring longitudinal direction;
- a flywheel (14) connected to said toothed ring (16, 16a) at said first end for common rotation therewith;
- a cover (18:
- 18a) connected to said toothed ring (16, 16a) at said second end (44;
- 44a) for common rotation therewith;
- and
- fastening means for connecting at least one component of said cover (18;
- 18a) and said flywheel (14) to said toothed ring, said fastening means comprising:
- a circumferential coupling region (48, 50, 24a, 50a) for producing a rotationally fixed coupling between the toothed ring (16;
- 16a) and said at least one component of said cover and said flywheel, said circumferential coupling region (48, 50, 24a, 50a) comprises circumferential retaining sections (48, 50, 24a, 50a), said circumferential retaining sections comprising an extension of at least one of said plural disc-driving teeth provided on said toothed ring (16;
- 16a) and an aperture arranged in said at least one component of said cover and said flywheel, said circumferential retaining sections for bearing against one another in the circumferential direction so that said extension of said at least one of said plural disc-diving teeth is inserted through said aperture;
- and
- an axial coupling region (54;
- 54a) for producing an axially fixed coupling between the toothed ring and said at least one component of said cover and said flywheel, said axial coupling region (54;
- 54a) comprising a retaining ring (54, 54a) adapted to engage said extension of said at least one of said plural disc-driving teeth of said tooth ring (16;
- 16a) inserted through said aperture and thereby prevent axial movement of said at least one component of said cover and said flywheel relative to said toothed ring.
