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.

Abstract: A housing for a multiplate clutch includes a toothed ring having a plurality of multiplate driver teeth arranged on an inner peripheral surface thereof distributed in the peripheral direction, and extending in a ring longitudinal direction. A flywheel disk is connected to the toothed ring at a first end of the same for common rotation. A cover is connected to the toothed ring at a second end of the same for common rotation. In this case, the toothed ring is connected to the flywheel disk by welding.

Abstract: The invention relates to a friction clutch in which an axial play is provided between an inner disk and a hub of a clutch disk. The axial play can be influenced by a device during assembly of the friction clutch in an engine and transmission of a motor vehicle drivetrain such that the hub is displaced, within the axial play, into the position in the axial play which lies closest to a flywheel of the friction clutch.

Abstract: A housing for a plate clutch having a toothed ring with a plurality of plate driving teeth which are arranged at an inner circumferential surface of the same so as to be distributed in the circumferential direction and which extend in a longitudinal direction of the ring. A flywheel is connected with the toothed ring at a first end of the same so as to rotate jointly therewith. A cover is connected with the toothed ring at a second end for joint rotation, wherein at least one of the flywheel and cover is connected with the toothed ring by a fastening arrangement. The fastening arrangement includes, in at least one of the plate driving teeth, a recess extending in the longitudinal direction of the ring and opening toward the one of either the flywheel and cover, and a fastening bolt element which is associated with this recess and which penetrates a fastening opening of either the flywheel or cover and projects into the associated recess.

Abstract: The invention is directed to a plate clutch with a housing having a front cover and axially projecting feet. The feet are provided with longitudinal bores through which fastening screws are guided. The fastening screws are constructed as expansion screws with a middle region which is reduced in diameter. The feet are provided with radial ventilation openings in the reduced diameter region of the fastening screws.

Abstract: The invention is directed to a plate clutch with improved heat removal characteristics. For this purpose, additional axial and radial aerating openings are arranged in the torque-transmitting teeth of the clutch housing.

Abstract: A friction clutch with a diaphragm spring which is fixed by a plurality of screws or rivets introduced at the housing. Each of these screws or rivets is surrounded by a spacer sleeve which is clamped between the housing and a circumferentially extending ring. Centering shoulders are provided in the ring for fixing the spacer sleeves, especially during operation.
