The driver is also made from a sheet metal part. A radial outer area of the driver has a shape corresponding to the ring element. The hub has a low weight and is produced economically.

Abstract: A hub assembly for a carbon/carbon clutch comprising a hub, a first clutch plate, and retaining means or locator releasably attachable to the first clutch plate thereby axially to define the position of the first clutch plate with respect to the hub.

Abstract: In a clutch for a motor vehicle, an axially displaceable contact-pressure disk has a number of driver elements guided by a guide and further driver elements which are supported with spring elements in another guide. In the disengaged state of the clutch, the spring elements preload the contact-pressure disk into a central position, in which the guided driver element is remote from a stop. This prevents the driver element from digging into the stop and hence prevents sticking of the contact-pressure disk in the engaged state of the clutch.

Abstract: A clutch assembly of an automatic transmission includes a clutch drum having a slanted inner surface at a corner formed by circumferentially bending an circumferential edge of the clutch drum, a plurality of friction members alternately arranged in the clutch drum, a piston for actuating the friction members, the piston contacting the friction members, and a cushion ring having a circumferentially slanted outer surface corresponding to the slanted inner surface of the clutch drum, the cushion ring being installed into the clutch drum so as to contact the slanted outer surface of the cushion ring with the slanted inner surface of the clutch drum.

Abstract: A multi-disk clutch 6 is provided with a reduced thickness so that the size of devices, such as a transmission employing the multi-disk clutch 6 can also be reduced. The multi-disk clutch 6 is configured to transmit and interrupt a torque between a radially outer wall 52 and a second cylindrical portion 69 of a spline hub. The multi-disk clutch 6 includes a plurality of first friction plates 50 and a plurality of second friction plates 51. Radially outer portions of the first friction plates 50 are coupled in a circumferential direction to the radially outer wall 52. Each second friction plate 51 has a core plate 90 and a friction facing 51a. The core plate 90 has a friction mounting portion opposed to the first friction plate 50, and tooth portions. The tooth portions are in mesh with the second cylindrical portion 69 of the spline hub. The friction facing 51a is joined to the friction mounting portion. The friction mounting portion has a smaller thickness than the tooth portion.

Abstract: A disc clutch wherein at least one first clutch disc, having internal teeth mating with the external splines of a first rotary hub, frictionally engages at least one second clutch disc, having external teeth mating with the internal splines of a second rotary hub coaxial with the first hub, when the clutch is engaged. Engagement of the clutch takes place in response to actuation of a cylinder-piston unit having a reciprocable piton which can directly or indirectly bear upon one of the two outer discs of the package including the first and second discs. The splines of the hubs and/or the teeth of the clutch discs are capable of undergoing deformation, particularly elastic deformation, to thus facilitate a more accurate selection of the magnitude of torque to be transmitted between the hubs by way of the frictionally engaged clutch discs.

Abstract: A clutch drum 15 is configured to reduce the weight of a clutch drum while keeping the mechanical losses of the clutch drum 15 in check. The clutch drum 15 houses several clutch plates 17 and has a cylindrical part 23 and a plurality of the teeth 25 that are arranged circumferentially around the inside of the cylindrical part 23 and extend in the axial direction. The teeth 25 have tooth cusps 29 and tooth flanks 31 on both rotational-direction sides. Bottom lands 35 are formed on the inside surface of the cylindrical part 23 between the teeth 25 in the axial direction. The outside recesses 37 are formed on the portions of the outside surface of the cylindrical part 23 that correspond to the teeth 25 and the inside recesses 27 are formed on the inside surfaces of the teeth 25.

Abstract: A transmission input shaft (116) is provided with spline teeth (144) of an involute cross-section and a relatively small circular thickness (146).

Abstract: The present invention comprises a textured separator plate having specific desirable surface characteristics and method of manufacture of said plate. The separator plate in one embodiment is fashioned from steel which is textured by cold working, for example, by a laser-matte rolling process. Preferably, the surface texture is a repeatable bi-dimensional pattern exhibiting a surface profile which is plateau-like in appearance, the texture comprising a regular pattern of curvilinear recesses defining island-like features.

Abstract: A power transmission has axially aligned torque transmitting mechanisms. Each torque transmitting mechanism has a backing plate slidably disposed on a spline formed in the housing of the power transmission. Each backing plate has a locating ring to limit the axial movement of the backing plate and therefore the members of the torque transmitting mechanism during engagement. The locating rings are disposed in an L-shaped groove such that the outer locating ring is narrower that the inner locating ring. The backing plate of one of the torque transmitting mechanisms has an outer segmented annular extension that is aligned with the narrower locating ring to prevent interference between the backing plates when the one torque transmitting mechanism is engaging.

Abstract: In a wet type multiplate clutch wherein outer tooth plates and inner tooth plates rotatable relative to each other are coaxially alternately disposed and are frictionally engaged with each other, of a plurality of oil grooves having opening portions opening to the inner peripheral edges of frictional materials secured to the inner tooth plates, at least 50 percent of the opening portions are opposed to a lubricant supply hole formed in a hub.

Abstract: A repair kit for a motor vehicle friction clutch, for example a motorcycle friction clutch, that is economical, simple to install, and which can extend the life of the original outer clutch hub, and a method for repairing the friction clutch. The kit can include an insert for insertion into the clutch. Additionally the kit can provide for the hardening of gear teeth in the clutch without the use of an insert. Additionally, a method for repairing a motorcycle friction clutch using a motorcycle clutch repair kit.

Abstract: A hub for a friction clutch with at least one clutch plate. The hub includes at least one axial guide device for the clutch plates and at least one stop device, which at least in part merge into one another without interfaces. The stop device is arranged in the radially outer area of the axially continuous guide device.

Abstract: A hydrodynamic torque converter wherein the housing is connected to the output element of an engine in the power train of a motor vehicle and receives a coaxial hub which is rotatable by the turbine wheel in the housing or by a clutch disk forming part of a lockup clutch and being axially movably but non-rotatably mounted on the hub. The lockup clutch further comprises a piston which is rotatably and axially movably mounted on the hub, and a laimina which is non-rotatably but axially movably mounted in the housing and extends radially inwardly between the piston and the clutch disk. The clutch is engaged when the piston is moved axially of the housing to thus urge the lamina against the clutch disk and to thus bias the clutch disk against an adjacent wall of the housing so that the clutch disc then transmits torque between the housing and the hub to thus bypass the torque transmitting connection between the housing and the hub by way of a satator wheel in the housing and the turbine wheel.
