A friction clutch includes a housing arrangement connectable to a drive element for rotation in common about an axis of rotation, a plurality of first friction disks connected to the housing arrangement such that the first friction disks are fixed with respect to rotation and axially movable relative to the housing arrangement, a hub rotatable about the axis of rotation relative to the housing arrangement and having a plurality of radially outward-projecting connection arms, a plurality of second friction disks defining engagement opening therein being closed on radial inner sides thereof, wherein the connection arms of the hub engage the engagement openings of the second friction disks such that the second friction disks are fixed with respect to rotation and axially movable relative to the hub, and a force-exerting arrangement exerting a force for urging the first friction elements and the second friction elements into contact with each other.

Friction clutch

A multi-disk clutch having a housing with a toothed ring and a cover connected to the toothed ring. The toothed ring, on an inner circumferential surface, has a plurality of disk carrier teeth distributed in the circumferential direction. At least one outer disk engages, of an external toothing, with the disk carrier teeth on the toothed ring. At least one inner disk is connected in rotation-proof fashion to a coupling hub. The clutch further has a pressure plate, and an energy storage device. The energy store device, in an outer circumferential area, has a recess associated with at least one disk carrier tooth that opens substantially radially outward and the disk carrier tooth engages in the recess.

Multi-disk clutch

A friction coupling for use in particular in the drive train of a motor vehicle includes a clutch casing, a pressure plate which is guided in a rotationally fixed manner with respect to the clutch casing, at least one clutch disk and a spring device containing about 40-60% nickel. A method for coating a nickel-base material, in particular the above mentioned spring element for friction clutches, wherein at least part of the surface of the spring device contains boride, and also a method for producing such a spring device which includes a heat treatment are also disclosed.

Friction clutch with nickel-chromium alloy spring elements

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.

Housing for a multiple-disc clutch

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.

Housing for a multiplate clutch

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.

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. The fastening bolt element can be or is brought into a fastening engagement at a fastening portion of the same with a counter-fastening component. In this respect, it is further provided that the counter-fastening component has a counter-fastening portion which is arranged or can be arranged in the recess and by which the fastening portion of the fastening bolt element can be brought into a fastening engagement.

Housing for a plate clutch

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.

Plate clutch

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.

Plate clutch for a motor vehicle

A friction clutch, preferably a multi-plate clutch, in which the pressure plate is made of carbon material and has a wear-resistant surface coating and/or an inserted wire ring in the contact area for the diaphragm spring.
