Abstract: An annular friction-clutch facing (30) for a multi-disk clutch (10) includes an inner edge (32) and an outer edge (34) defining a width (w) of the facing (30). The facing (30) further includes a first group of grooves (136, 236) formed on the facing (30) and having first cross-sectional area. Each groove of the first group (136, 236) has a first opening (38) at the outer edge (34) and a second opening (40) at the inner edge (32) remote from the first opening (38) and is adapted to direct lubricating agents across the width (w) over a substantial area of the facing (30). The facing (30) further includes a second group of grooves (42) formed on the facing (30) and having a second cross-sectional area smaller than the first cross-sectional area. The second group of grooves (42) includes first and second sets of grooves (44, 46, respectively). The grooves of the first set (44) are disposed in intersecting relationship with the grooves of the second set (46).

Abstract: A multiple-clutch assembly includes a housing and a first clutch having a first drive member rotatably supported within the housing on a drive hub and a first driven member rotatably supported within the housing on a first driven shaft. A first clutch pack is interposed between the first drive and driven members and operable to selectively connect and disconnect the first drive and driven members for transferring and interrupting torque between the first drive and driven members. A second clutch is supported within the housing coaxial with respect to the first clutch and includes a second drive member rotatably supported within the housing on the drive hub and a second driven member rotatably supported within the housing on a second driven shaft. The first and second driven shafts are disposed concentrically relative to one another.

Abstract: A multi-disk friction device includes a drive member having a plurality of drive disks supported for rotation with the drive member and a driven member having a plurality of driven disks supported for rotation with the driven member. The drive and driven disks are interleaved relative to each other such that each drive disk is adjacent to a driven disk and moveable toward and away from one another for providing selective frictional engagement therebetween and to transmit torque between the drive and driven members. Each of the drive and driven disks include a working face which is disposed for frictional engagement with the working face of an adjacent one of the disks. At least one of the working faces on an adjacent one of the disks includes a plurality of micro-pockets formed thereon. The micro-pockets act to store lubricating agents on the working faces.

Abstract: A disk assembly having a circular friction lining mounted on one or both sides of a support member. An oil channel extends from the outer edge of the friction lining to the inner edge. The oil channel includes an enlarged middle oil reservoir section extending completely through the friction lining. An inlet section and an outlet section of the oil channel are in communication with the reservoir section and are narrow grooves which are embossed in the friction lining during bonding of the friction lining.

Abstract: The free-wheel has an inner ring (30, 138) and an outer ring (32, 140). Generally bone-shaped clamping elements (18, 116) are located between the rings (30, 32; 138, 140) which are provided with an outer radial thickening (24), a central waist (22, 152) and an inner radial thickening (20, 150). A cage ring (10, 142) that guides the clamping elements (18, 116) in a synchronous manner is arranged at the height at the inner radial thickening (20, 150). The cage ring (10, 142) consists of two cage ring segments (34, 144) that have an axial distance to each other and axial webs (38, 146) that connect the same and between which pockets (14, 148) for the clamping elements (18, 116) are formed. The cage ring (10, 142) consists of a viscoelastic plastic material, in particular an elastomer.

Abstract: A freewheel assembly is disclosed. The freewheel includes an internal cage ring made of a rigid material such as a metal. An external cage ring which is made of a flexible material such as a plastic surrounds the internal cage ring. Projections extend from the frontal surfaces of the external cage ring. The projections define cams for engaging a surrounding member.

Abstract: A friction assembly is disclosed. A support plate which functions as a friction lining support, is connected with hub plates which are placed against both its frontal sides by using slitted spring collets.

Abstract: By complete removal of the friction lining material, grooves or slots are formed in a friction lining made of organic material, the grooves being openings or gaps that are initially closed at the ends. The friction lining is applied as a continuous member onto a support and the ends of the grooves are opened by removal of the friction lining material closing them.

Abstract: A double cage structure for a freewheel sprag clutch in which the inner cage ring is formed of metal and the outer cage ring is formed of a plastic material.
